A new paper in the Journal of the European Economic Association, published by Oxford University Press, indicates that we tend to listen to people who tell us things we'd like to believe and ignore people who tell us things we'd prefer not to be true. As a result, like-minded people tend to make one another more biased when they exchange beliefs with one another.
The Met Gala is a barometer of fashion. Not in the boring "What is the hemline of the moment?" sense, but on a grander scale. This benefit dinner is pure spectacle, an event that exists only to be photographed, a sequined media mirage. Look at the pictures from the after-parties and you'll see that many guests change out of their red-carpet looks as soon as humanly possible. These are clothes for
In the UK, the majority of those now in hospital with Covid-19 are unvaccinated. Many face their last days with enormous regret, and their relatives are telling their stories to try to convince others like them Matt Wynter, a 42-year-old music agent from Leek, Staffordshire, was working out in his local gym in mid-August when he saw, to his great surprise, that his best friend, Marcus Birks, was
Marine Cloud Brightening From carbon capture machines to covering glaciers with giant blankets , there's no shortage of ideas on how to combat the effects of anthropogenic climate change. Now, a team of atmospheric scientists want to create whiter clouds that reflect more sunlight to cool down the Earth. The project, first spotted by Interesting Engineering , focuses on a theoretical method of ge
It is the elephant in the genomics room: can extinct species be resurrected? One bioscience firm insists they can, announcing Monday its intent to use emerging technology to restore the woolly mammoth to the Arctic tundra.
A new study suggests that all living snakes evolved from a handful of species that survived the giant asteroid impact that wiped out the dinosaurs and most other living things at the end of the Cretaceous. The authors say that this devastating extinction event was a form of 'creative destruction' that allowed snakes to diversify into new niches, previously filled by their competitors.
New Curtin research has found the moon may have been subjected to much greater impacts from asteroids and other bodies than previously thought, building on our understanding of the moon's earliest geologic evolution.

Chris Whitty says disruption 'extraordinarily difficult for children' and informed decision to recommend vaccinating 12- to 15-year olds UK children aged 12 to 15 to be offered Covid jab Fully vaccinated people account for 1.2% of England's Covid-19 deaths Vaccine booster programmes not appropriate now, say global experts Starmer insists Labour does have alternative approach to social care Summar
Three weeks before the release of Marvel's latest superhero movie, Shang-Chi and the Legend of the Ten Rings , the lead actor and the distributor seemed poised for their own showdown. Bob Chapek, Disney's CEO, had described the film as an "interesting experiment," given that it would be the company's first franchise title since the beginning of the coronavirus pandemic to hit theaters without sim
Scientists at the University of Manchester have come up with a macabre new way to turn Martian soil into a stronger material for the construction of future colonies on the Red Planet. Specifically, they suggest mixing human blood, urine, sweat or even tears with Moon or Mars dust to form a glue that can be used to build — or 3D print — entire buildings. In other words, they say we could use the t
New research provides insights into how the position and intensity of the North Atlantic jet stream has changed during the past 1,250 years. The findings suggest that the position of the jet stream could migrate outside of the range of natural variability by as early as the year 2060 under unabated greenhouse gas emissions, with potentially drastic weather-related consequences for societies on bot
Researchers studying weight gain believe global obesity trends might be driven more by the types of food we eat rather than how much we eat. Their findings, published The American Journal of Clinical Nutrition , argue that the energy-balance model (EBM), the dominant medical framework which holds that weight gain is caused by consuming more calories than you burn, is no longer widely applicable d

P erhaps you've noticed that ebooks are awful. I hate them, but I don't know why I hate them. Maybe it's snobbery. Perhaps, despite my long career in technology and media, I'm a secret Luddite. Maybe I can't stand the idea of looking at books as computers after a long day of looking at computers as computers. I don't know, except for knowing that ebooks are awful . If you hate ebooks like I do, t
American colleges and universities now enroll roughly six women for every four men. This is the largest female-male gender gap in the history of higher education, and it's getting wider. Last year, U.S. colleges enrolled 1.5 million fewer students than five years ago, The Wall Street Journal recently reported . Men accounted for more than 70 percent of the decline. The statistics are stunning. Bu
People with macular degeneration, cataracts and diabetes-related eye disease at greater risk Millions of people with eye conditions including age-related macular degeneration, cataracts and diabetes-related eye disease have an increased risk of developing dementia, new research shows. Vision impairment can be one of the first signs of the disease, which is predicted to affect more than 130 millio
In June, San Francisco-based startup Orbit Fab launched a prototype refueling station into Earth's orbit — but rather than allowing astronauts to venture into deep space, this system is meant to give old satellites a new lease on life. That's a compelling idea, and now the company has locked down $10 million in funding to further it. Our planet's orbit is getting cluttered with old and new satell
Members of Congress have put forward a bill that would give electric vehicle companies with unionized workers a tax incentive . That means many automakers in the US, including Ford, would benefit — but not Tesla, since its workers aren't unionized. And that has Tesla CEO Elon Musk incensed. "This is written by Ford/[United Auto Workers] lobbyists, as they make their electric car in Mexico," Musk
Imagine you're a general in ancient times and you want to keep your troop counts secret from your enemies. But you also need to know this information yourself. So you turn to a math trick that allows you to achieve both aims. In a morning drill you ask your soldiers to line up in rows of five. You note that you end up with three soldiers in the last row. Then you have them re-form in rows of eigh
Garbage Removal Apple co-founder Steve Wozniak gave almost nothing away this morning with his cryptic announcement of Privateer, a space company he promised to be "unlike the others." A video accompanying the announcement also wasn't exactly enlightening, teasing only that the venture would make space more "accessible" and "safe." But, according to the hawk-eyed reporters over at Gizmodo , we may
A decade before United Nations climate scientists issued a "code red for humanity," the 20-year-old college junior Evan Weber joined several thousand protesters descending on Wall Street to declare a code red for democracy. At the height of the Great Recession, Weber and his generation saw the climate crisis staring them in the face, along with exploding wealth and income inequality, student debt
Reducing naturally occurring errors in protein synthesis (production) improves both health and lifespan, finds a new study in simple model organisms led by researchers at UCL and MRC London Institute of Medical Sciences.
Calithera Biosciences is a small, Northern California immunotherapy company with a pipeline of drugs in various stages of premarket development for cancer and cystic fibrosis. Like any manufacturer creating complex new products, Calithera keeps track of lots of data. But unlike advanced technology companies in other fields, drug discovery companies have the US Food and Drug Administration constan
The day I was diagnosed with cancer—serious cancer, out-of-the-blue cancer—I reeled out of the doctor's office and onto the familiar street. My children's dentist was on that block, and the Rite Aid where we got cheap toys after their checkups. Just an hour and a half earlier, I'd walked down that street and my world had been safe and whole—my two little boys, my good husband, my career as a writ
A team of researchers affiliated with a large number of institutions in India and the U.S. has found a rare genotype in an isolated tiger population that explains its dark wide stripes. In their paper published in Proceedings of the National Academy of Sciences, the group describes their genetic study of pseudomelanistic tigers at India's Nandankanan Biological Park.
A team of astronomers from Switzerland and Germany has conducted a long-term multi-band photometric monitoring of a nearby blazar known as Markarian 501. The observational campaign delivered essential information regarding the blazar's variability and detected numerous flares from this source.

The Four Americas Competing visions of the country's purpose and meaning are tearing it apart, George Packer wrote in the July/August issue. Is reconciliation possible? George Packer's article had me nodding and shaking my head in alternation, and in the end caused me heartache that only a beer and a ball game could alleviate. I doubt America was ever as unified before World War II as Packer sugg
The long-running series in which readers answer other readers' questions on subjects ranging from trivial flights of fancy to profound scientific and philosophical concepts I understand that tears flush away foreign objects from the eye. But what advantage does crying have when one is feeling sad (or happy)? Perhaps it is to signal an extreme of emotion, but then why would a solitary sad person c
According to the Union of Concerned Scientists (UCS), over 4,000 operational satellites are currently in orbit around Earth. According to some estimates, this number is expected to reach as high as 100,000 by the end of this decade, including telecommunication, internet, research, navigation, and Earth Observation satellites. As part of the commercialization of low Earth orbit (LEO) anticipated in
Late one recent afternoon, Chesa Boudin logged on to Zoom to have a conversation with me while his wife was in labor. His critics see the 41-year-old San Francisco district attorney as a symbol of the progressive legal-reform movement's excesses . But Boudin has also attracted national attention because his personal story is so extraordinary: When he was barely a toddler, his parents, David Gilbe

Sometimes, when you feed an AI content from the Internet, it learns natural language. Sometimes, it reads the entire contents of GitHub and learns to produce simple snippets of code. This is the story of what happens when the AI does both. Neural networks are all the rage these days. From Siri to self-driving, to protein folding and medical diagnostics, the powerful duo of machine learning and bi
New research led by the University of Oxford, published in Conservation Letters, has examined the conflict between small-scale fisheries and marine mammals, using the experience of fisheries on the west coast of South America to highlight a worldwide issue.
An international collaboration has identified what may be the oldest work of art, a sequence of hand and footprints discovered on the Tibetan Plateau. The prints date back to the middle of the Pleistocene era, between 169,000 and 226,000 years ago – three to four times older than the famed cave paintings in Indonesia, France and Spain.
Since the spread of virus causing COVID-19 continues, experts recommended wearing homemade facemasks when surgical or N95 masks are not available to prevent the spread of the pandemic. While such makeshift masks are more economical and accessible in low-capita countries, the effectiveness of cloth masks has not been studied in depth.

Imagine you've just sat down to watch your favorite TV show. You decide to snuggle in with your legs crisscrossed because you find it more comfortable that way. When the episode ends, you try to stand up and suddenly your right foot isn't working. At first you just can't move it, then it feels like it has pins and needles all over it. For a minute or two it feels uncomfortable and weird, but soon
The government of the Faroe Islands, an autonomous Danish territory, faced an outcry on Tuesday over the culling of more than 1,400 white-sided dolphins in a day in what was said to be the single biggest hunt in the northern archipelago.
For some 1,000 years, many Ashkenazi Jews have observed the same ritual every Yom Kippur Eve—waving a chicken over their head. The practice is called kapparot (atonements) in Hebrew and "shluggen kappores" in Yiddish. Shluggen means beating or hitting, which is not what the ceremony entails, but probably what it feels like to the chicken. "Whenever you move and get your body involved in the act o
The health and diversity of Australian ecosystems are in decline. The environment is under mounting pressure from land clearing, altered fire regimes and invasive species. Australian ecosystems are also extremely vulnerable to climate impacts with extreme temperatures and fires expected to become more frequent and more severe.
The natural world served as the inspiration for the Ohio State University scientists whose microscope images were announced Monday (Sept. 13) among the top 20 winners in the 2021 Nikon Small World Photomicrography Competition.
Chronic infected wounds are often highly problematic for diabetic patients. However, a team of Chinese researchers has now developed a targeted approach to wound healing that makes use of nanomedicine, and their research has been published in the journal Angewandte Chemie. The researchers were able to deactivate wound-infecting bacteria using a solution of nanocapsules that alter the wound environ
Magnets formed from a single molecule are of particular interest in data storage, since the ability to store a bit on every molecule could vastly increase the storage capacity of computers. Researchers have now developed a new molecular system with a particular magnetic hardness.

New research documents major differences in potential family caregiver availability by the gender, race, ethnicity, education level, and family structure of the person with dementia. The study offers stark statistics about a reality that 6 million Americans with dementia and their families live every day: one where people with dementia receive hundreds of hours a month in unpaid care from spouses
Hospitalized COVID-19 patients are substantially more likely to harbor autoantibodies –antibodies directed at their own tissues or at substances their immune cells secrete into the blood — than people without COVID-19, according to a new study.
Does hanging out with Alexa or Siri affect the way kids communicate with people? Probably not, researchers report. A new study finds kids are sensitive to context when it comes to conversation. Chatting with a robot is now part of many families' daily lives, thanks to conversational agents such as Apple's Siri or Amazon's Alexa. Recent research shows that children are often delighted to find that
Early stages of colorectal cancer (CRC) development are characterized by a complex rewiring of transcriptional networks resulting in changes in the expression of multiple genes. Here, we demonstrate that the deletion of a poorly studied tetraspanin protein Tspan6 in Apcmin/+ mice, a well-established model for premalignant CRC, resulted in increased…
Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by skin dryness, inflammation, and itch. A major hallmark of AD is an elevation of the immune cytokines IL-4 and IL-13. These cytokines lead to skin barrier disruption and lipid abnormalities in AD, yet the underlying mechanisms are unclear. Sebaceous…
Northern peatlands store large amounts of carbon. Observations indicate that forests and peatlands in northern biomes can be alternative stable states for a range of landscape settings. Climatic and hydrological changes may reduce the resilience of peatlands and forests, induce persistent shifts between these states, and release the carbon stored…
CtIP is a DNA end resection factor widely implicated in alternative end-joining (A-EJ)–mediated translocations in cell-based reporter systems. To address the physiological role of CtIP, an essential gene, in translocation-mediated lymphomagenesis, we introduced the T855A mutation at murine CtIP to nonhomologous end-joining and Tp53 double-deficient mice that routinely succumbed to…
Directed trophoblast migration toward the maternal mesometrial pole is critical for placentation and pregnancy success. Trophoblasts replace maternal arterial endothelial cells to increase blood supply to the placenta. Inferior trophoblast invasion results in pregnancy complications including preeclampsia, intrauterine growth restriction, miscarriage, and preterm delivery. The maternal chemotactic
Eukaryote–eukaryote endosymbiosis was responsible for the spread of chloroplast (plastid) organelles. Stability is required for the metabolic and genetic integration that drives the establishment of new organelles, yet the mechanisms that act to stabilize emergent endosymbioses—between two fundamentally selfish biological organisms—are unclear. Theory suggests that enforcement mechanisms, which pu
Rechargeable magnesium batteries represent a viable alternative to lithium-ion technology that can potentially overcome its safety, cost, and energy density limitations. Nevertheless, the development of a competitive room temperature magnesium battery has been hindered by the sluggish dissociation of electrolyte complexes and the low mobility of Mg2+ ions in solids,…
Viscoelastic flows through porous media become unstable and chaotic beyond critical flow conditions, impacting widespread industrial and biological processes such as enhanced oil recovery and drug delivery. Understanding the influence of the pore structure or geometry on the onset of flow instability can lead to fundamental insights into these processes…
Mayflies (order Ephemeroptera), insects favored as food by freshwater fish and as models for the artificial lures of fly fishers, live double lives. During their immature (nymphal) stages, they pursue an underwater career for 1 y or 2 y, molting their cuticular exoskeleton on numerous occasions as they grow. As…
In the 19th century, Ilya Metchnikoff defined and broadened our initial understanding of phagocytosis and, in 1908, went on to show that a cellular component (i.e., DNA) stimulates immune responses (1). About a century later, Janeway conceptualized pattern recognition receptors (PRRs) and pathogen-associated molecular patterns (PAMPs) (2). Since then, we…
This is an excerpt from The Atlantic 's climate newsletter, The Weekly Planet. Subscribe today . The climate scientist Ken Caldeira recently tweeted a joke meant to charm carbon-tax advocates. "If we don't want people to drink so much alcohol, rather than taxing alcohol, we can subsidize everything that is not alcohol," he wrote . His point, if I may ruin the punch line, is that the United States
Predicting where anthropogenic debris accumulates in aquatic ecosystems is necessary for its control and environmental remediation, but plastic and fiber pollution in lakes is not well studied. A study published in PLOS Biology by Andrew Tanentzap at University of Cambridge, United Kingdom and colleagues suggests that microparticle concentrations in lakes are higher than previously reported, and t
At a time when many municipalities are seeking to control urban stormwater by investing heavily in green infrastructure—such as water-quality ponds, infiltration basins, porous pavement and riparian plantings—a new study suggests that these expensive efforts may not have much of an impact.
A new report on the value and vulnerability of juvenile salmon habitat in northern BC's Skeena River reveals how climate change and development are critically impacting the region—and provides a historical assessment to help inform the region's future planning. Collaborators from the Lax Kw'alaams Fisheries Program, the Skeena Fisheries Commission and Simon Fraser University say proactive stewards
While social distancing and wearing masks kept last year's flu season at an all-time low, experts expect flu cases will soar this year as students return to school and employees go back to the office. They're urging people to get their flu vaccine to prevent the nation's health care system from being overwhelmed by influenza and COVID-19 . Here, David Cennimo, an infectious disease expert at Rutg
När Parisavtalet klubbades år 2015 var det många unga som kände hopp. Världens beslutsfattare skulle gå samman för att bromsa den globala uppvärmningen – men nu visar ny forskning att världens unga i stället känner sig svikna. En internationell forskargrupp med psykologer, psykiatriker och psykoterapeuter från sex olika universitet har undersökt ungas inställning till klimatet. Undersökningen omfa
To prevent the present from erasing the past, non-profit organizations are creating detailed 3D scans of famous monuments. Stored online and shared with researchers around the world, these digital copies will endure long after their real counterparts are gone. Occasionally, this work is incredibly dangerous. On the night of May 14, 1940, the German Luftwaffe bombed the Dutch city of Rotterdam. Wh
In order to navigate a complex web of relationships, an individual must learn and represent the connections between people in a social network. However, the sheer size and complexity of the social world makes it impossible to acquire firsthand knowledge of all relations within a network, suggesting that people must…
Dendritic cells (DC), macrophages, and monocytes, collectively known as mononuclear phagocytes (MPs), critically control tissue homeostasis and immune defense. However, there is a paucity of models allowing to selectively manipulate subsets of these cells in specific tissues. The steady-state adult kidney contains four MP subsets with Clec9a-expression history that include…
Most endangered species exist today in small populations, many of which are isolated. Evolution in such populations is largely governed by genetic drift. Empirical evidence for drift affecting striking phenotypes based on substantial genetic data are rare. Approximately 37% of tigers (Panthera tigris) in the Similipal Tiger Reserve (in eastern…
Reopening schools is an urgent priority as the COVID-19 pandemic drags on. To explore the risks associated with returning to in-person learning and the value of mitigation measures, we developed stochastic, network-based models of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission in primary and secondary schools. We find that…
NACHT, LRR, and PYD domains–containing protein 3 (NLRP3) inflammasome activation is beneficial during infection and vaccination but, when uncontrolled, is detrimental and contributes to inflammation-driven pathologies. Hence, discovering endogenous mechanisms that regulate NLRP3 activation is important for disease interventions. Activation of NLRP3 is regulated at the transcriptional level and by.
Hybrids between species can harbor a combination of beneficial traits from each parent and may exhibit hybrid vigor, more readily adapting to new harsher environments. Interspecies hybrids are also sterile and therefore an evolutionary dead end unless fertility is restored, usually via auto-polyploidisation events. In the Saccharomyces genus, hybrids are…
Triple-negative breast cancer (TNBC) is a breast cancer subtype that lacks targeted treatment options. The activation of the Notch developmental signaling pathway, which is a feature of TNBC, results in the secretion of proinflammatory cytokines and the recruitment of protumoral macrophages to the tumor microenvironment. While the Notch pathway is…
Bladder cancer (BC) has a 70% telomerase reverse transcriptase (TERT or hTERT in humans) promoter mutation prevalence, commonly at −124 base pairs, and this is associated with increased hTERT expression and poor patient prognosis. We inserted a green fluorescent protein (GFP) tag in the mutant hTERT promoter allele to create…
Understanding the role of nonequilibrium driving in self-organization is crucial for developing a predictive description of biological systems, yet it is impeded by their complexity. The actin cytoskeleton serves as a paradigm for how equilibrium and nonequilibrium forces combine to give rise to self-organization. Motivated by recent experiments that show…
Reconstruction of the North Atlantic jet stream (NAJ) presents a critical, albeit largely unconstrained, paleoclimatic target. Models suggest northward migration and changing variance of the NAJ under 21st-century warming scenarios, but assessing the significance of such projections is hindered by a lack of long-term observations. Here, we incorporate insights from…
The narrow genetics of most crops is a fundamental vulnerability to food security. This makes wild crop relatives a strategic resource of genetic diversity that can be used for crop improvement and adaptation to new agricultural challenges. Here, we uncover the contribution of one wild species accession, Arachis cardenasii GKP…
Research has shown that Black parents are more likely than White parents to have conversations about race with their children, but few studies have directly compared the frequency and content of these conversations and how they change in response to national events. Here we examine such conversations in the United…
Food security has been a significant issue for the livelihood of smallholder family farms in highly populated regions and countries. Industrialized farming in more developed countries has increased global food supply to meet the demand, but the excessive use of synthetic fertilizers and pesticides has negative environmental impacts. Finding sustainable…
Extracellular vesicles (EVs) are constantly secreted from both eukaryotic and prokaryotic cells. EVs, including those referred to as exosomes, may have an impact on cell signaling and an incidence in diseased cells. In this manuscript, a platform to capture, quantify, and phenotypically classify the EVs secreted from single cells is…
The angle of repose—i.e., the angle θr between the sloping side of a heap of particles and the horizontal—provides one of the most important observables characterizing the packing and flowability of a granular material. However, this angle is determined by still poorly understood particle-scale processes, as the interactions between particles…
Molecular chaperones are key components of the cellular proteostasis network whose role includes the suppression of the formation and proliferation of pathogenic aggregates associated with neurodegenerative diseases. The molecular principles that allow chaperones to recognize misfolded and aggregated proteins remain, however, incompletely understood. To address this challenge, here we probe…
Americans remain unaware of the magnitude of economic inequality in the nation and the degree to which it is patterned by race. We exposed a community sample of respondents to one of three interventions designed to promote a more realistic understanding of the Black–White wealth gap. The interventions conformed to…
Genome remethylation is essential for mammalian development but specific reasons are unclear. Here we examined embryonic stem (ES) cell fate in the absence of de novo DNA methyltransferases. We observed that ES cells deficient for both Dnmt3a and Dnmt3b are rapidly eliminated from chimeras. On further investigation we found that…
Embryonic development leads to the reproducible and ordered appearance of complexity from egg to adult. The successive differentiation of different cell types that elaborate this complexity results from the activity of gene networks and was likened by Waddington to a flow through a landscape in which valleys represent alternative fates….
Simulation techniques based on accurate and efficient representations of potential energy surfaces are urgently needed for the understanding of complex systems such as solid–liquid interfaces. Here we present a machine learning framework that enables the efficient development and validation of models for complex aqueous systems. Instead of trying to deliver…
MacDonald and Tonegawa (1) show that inhibiting projections from dorsal CA2 to CA1 impairs performance on a delayed spatial alternation task and destabilizes sequences of neural activity in CA1 (Fig. 1). Notably, the effect on behavior is only observed if CA2 inputs are inhibited during the delay, and the effect…
Amyloid fibrillization is an exceedingly complex process in which incoming peptide chains bind to the fibril while concertedly folding. The coupling between folding and binding is not fully understood. We explore the molecular pathways of association of Aβ40 monomers to fibril tips by combining time-resolved in situ scanning probe microscopy…
Aire controls immunological tolerance by driving promiscuous expression of a large swath of the genome in medullary thymic epithelial cells (mTECs). Its molecular mechanism remains enigmatic. High-resolution chromosome-conformation capture (Hi-C) experiments on ex vivo mTECs revealed Aire to have a widespread impact on higher-order chromatin structure, disfavoring architectural loops while…
Bluefin tuna (BFT), highly prized among consumers, accumulate high levels of mercury (Hg) as neurotoxic methylmercury (MeHg). However, how Hg bioaccumulation varies among globally distributed BFT populations is not understood. Here, we show mercury accumulation rates (MARs) in BFT are highest in the Mediterranean Sea and decrease as North Pacific…
The most ubiquitous cyanobacteria, Synechococcus, have colonized different marine thermal niches through the evolutionary specialization of lineages adapted to different ranges of temperature seawater. We used the strains of Synechococcus temperature ecotypes to study how light utilization has evolved in the function of temperature. The tropical Synechococcus (clade II) was…
Robust polymeric nanofilms can be used to construct gas-permeable soft electronics that can directly adhere to soft biological tissue for continuous, long-term biosignal monitoring. However, it is challenging to fabricate gas-permeable dry electrodes that can self-adhere to the human skin and retain their functionality for long-term (>1 d) health monitoring….
In a recent letter (1), Lehr and Stöber argue against our interpretation of neural activity during the mnemonic delay period of a spatial working memory task as temporal coding (2). Because external cues (environmental and body derived) are kept constant during this period, they suggest activity reflects internally driven maintenance…

In times of exacerbating biodiversity loss, reliable data on species occurrence are essential. Environmental DNA (eDNA) – DNA released from organisms into the water – is increasingly used to detect fishes in biodiversity monitoring campaigns. However, eDNA turns out to be capable of providing much more than fish occurrence data, including information on other vertebrates. A study demonstrates how
Scientists report a vampire fish attached to the body of an Amazonian thorny catfish. Very unusually, the candirus were attached close to the lateral bone plates, rather than the gills, where they are normally found. Since the hosts were not badly harmed, and the candirus apparently derived no food benefit, scientists believe this association is commensalistic rather than parasitic.
The green crab, Carcinus maenas, is considered a globally distributed invasive species, an organism introduced by humans that eventually becomes overpopulated, with increased potential to negatively alter its new environment. Traditionally, it's been assumed that successful populations contain high genetic diversity, or a variety of characteristics allowing them to adapt and thrive. On the contrar
All cells need ribosomes to make the proteins necessary for life. These multi-component molecular machines build complex proteins by stitching building blocks together according to instructions encoded in the cell's messenger RNAs. But ribosomes are themselves composed of small and large subunits, each of which is made up of ribosomal proteins and RNA. Before they can manufacture proteins, these s

The retraction wasn't unexpected. Ariely and his colleagues said last month that they … Continue reading
Global obesity rates are on the rise, but body shaming campaigns are doing more harm than good, says medical anthropologist Nancy N. Chen. Reflecting on how the cultural histories of body ideals have changed over time, she offers a new way to view ourselves and our health by enhancing body diversity to close the gap between what's ideal and what's real.
There are a lot of products out there that promise to improve your sex life . Unfortunately, most of them don't improve diddly squat. They are just shameless attempts to cash in on male insecurities. That being said, not all sexual wellness products are useless. Some of them—usually the ones designed by actual experts using science and data—really do work. And one of them is the MYHIXEL MED , a r
Scientists from Brown University have created tiny microchips, designed to be scattered over the brain's surface — or even within its tissue — in order to collect an unprecedented wealth of neural data. The researchers call the chips "neurograins," according to Wired . Each is roughly the size of a grain of salt, and are intended to be spread throughout brain tissue where it can record brain acti
Researchers have imaged the atoms at the surface of the light-absorbing layer in a new type of next-generation solar cells, made from a crystal material called metal-halide perovskite. Their findings have solved a long-standing mystery in the field of solar power technology, showing how power-boosting and stability-enhancing chlorine is incorporated into the perovskite material.

Would you feel depressed if it has rained for several days? Sunshine affects our mood. The medical sector generally believes that seasonal affective disorder (SAD) is related to shorter sunshine duration in autumn and winter, as sunlight affects the activity of the brain. A study participated by an accounting scholar from City University of Hong Kong (CityU) found that if the weather is sunny imme
It is a fundamental truth of human behavior that people sometimes cheat. And yet, we tend to have strong moral judgements against cheating, which leads to anti-cheating social pressure. How does this all play out in the human brain? Psychologists have tried to understand this within the standard neuroscience paradigm – that people have basic motivations mostly designed to meet fundamental needs,
Inside the New Zealand Ice Core Research Facility, scientists like Dr. Holly Winton from the Te Puna Pātiotio—Antarctic Research Centre at Te Herenga Waka—Victoria University of Wellington analyze ice core samples to understand how and why the climate changed in the past, to better predict our future.
