A new study examines whether pregnancy changes mothers' neural sensitivity to infants' facial cues, and whether such changes affect mother-infant bonding. The study finds that increases in cortical responses to infants' faces from the prenatal to the postnatal period in individual mothers are associated with more positive relationships with the baby (as reported by the mothers) after birth.
Until now, research exploring how and why cute aggression occurs has been the domain of behavioral psychology. But recently, a licensed clinical psychologist with a background in neuroscience has taken formal study of the phenomenon a few steps further. To her knowledge, the results of her latest study are the first to confirm a neural basis for cute aggression.
Researchers have demonstrated a new level of control over photons encoded with quantum information. The team's experimental system allows them to manipulate the frequency of photons to bring about superposition, a state that enables quantum operations and computing.

A new study published in the Journal of Developmental Origins of Health and Disease finds that mothers' stress levels at the moment they conceive their children are linked to the way children respond to life challenges at age 11. SFU health sciences professor Pablo Nepomnaschy led an interdisciplinary research team on this first cohort study.
When the tiny and invasive spiny water flea began appearing in UW-Madison researchers' nets in 2009, scientists began to wonder how Lake Mendota, one of the most-studied lakes in the world, went from flea-free to infested seemingly overnight, undetected by trained technicians. A new report published in the journal Ecosphere says Lake Mendota's story may be the rule, rather than an exception.
A contentious debate among diabetes researchers has surrounded the regeneration of pancreatic insulin-producing cells: not if these cells regenerate, but rather how. Diabetes Research Institute scientists now draw categorical conclusions that pancreatic progenitors do exist. The prevailing theory, they say, is based upon an unreliable tool in an inadequate model.
The Flint, Michigan lead crisis should have buried the city in waste. A Purdue University case study investigates why not and proposes solutions for future water disasters.

With news coverage being a constant cycle and information being amplified across social media channels, it can be difficult to discern between sound news and 'fake news.' As a result people's trust in scientific information has begun to break down. This is especially harmful to society when the mass dissemination of misinformation, especially as it relates to issues such as climate change, is prob
Many of the substances that humans consume on a regular basis as parts of their basic diet actually contain harmful toxins. Rice, barbecued meat and drinking water all pose threats to human health as hosts to potent toxins, carcinogens and opportunistic pathogens. In many cases, the rise in concentrations of these harmful substances is a direct result of human activity, such as the use of harmful
In the US, more than 100 food recalls were issued in 2017 because of contamination from harmful bacteria such as Listeria, Salmonella or E. coli. A new sensor design could one day make it easier to detect pathogens in food before products hit the supermarket shelves, thus preventing sometimes-deadly illnesses from contaminated food.
In the hours and days after a traumatic injury, the gears of circadian clocks fall profoundly out of sync, disrupting body temperature, hormonal rhythms, and immune response, new research shows.
New study shows low use of telehealth services for substance use disorder. More than 20 million Americans have substance use disorders related to alcohol, opioids and other drugs.Less than one in five receive treatment for substance use disorder, in part because of lack of providers, especially in rural areas.

Conditions encountered in the womb can have life-long impact on health. Scientists previously assumed this is because embryos respond to adverse conditions by programming their gene expression. Now scientists report a radically different alternative. Rather than being programmed by the environment, random differences in gene expression may provide some embryos with a survival advantage. The resear
An important new study provides the first direct evidence that intact zinc oxide nanoparticles neither penetrate the human skin barrier nor cause cellular toxicity after repeated application to human volunteers under in-use conditions. This confirms that the known benefits of using ZnO nanoparticles in sunscreens clearly outweigh the perceived risks, researchers say.
Tropical Cyclone Owen appeared disorganized on satellite imagery as it moved through the Coral Sea in the Southern Pacific Ocean. Imagery from the Suomi NPP satellite showed that Owen was being stretched out and had weakened from wind shear.
African resistance strongly shaped Spanish Hispaniola of the 1500s— now the island home to Haiti and the Dominican Republic—but historians have often considered that resistance to be a byproduct of Spanish colonialism and its reliance on slavery, according to a University of Kansas historian who studies the development of race in Latin America.
With a new crew arriving at the International Space Station, astronauts will be relieved to know that they won't have to worry about a major aspect of their immune system being compromised. While researchers know a lot about astronauts' skeletal and muscular health during spaceflight and when they return to Earth, much less is known about how spaceflight affects immunity. It has been generally tho

Flavor, the conjunction of taste and smell, is not a sensation that yields easily to analysis. Unlike sights and sounds, which can be captured by cameras and microphones, there is no widespread way to measure flavor. What people experience when they eat has heretofore been largely ineffable and uncomputable. "If I go to a farmers' market, I can take a picture of a really lovely mushroom, but I ca
American girls have been hitting puberty at earlier ages compared to past decades. Chemicals found in common cosmetic products could be responsible for the changes, according to the results of a nearly 20-year study, which found that boys didn't seem to be affected by the same chemicals. It's still unclear whether these chemicals cause early puberty, but it might be worth avoiding products contai
A new synthetic material will make solar energy a more cost-effective, efficient, and reliable source of power Clean energy is at a crossroads.

Karplus et al. (1) raise the concern of potential data manipulation by coal-fired power plants in China by comparing Continuous Emissions Monitoring Systems (CEMS) data with NASA satellite data. Since the two sources of data are not directly comparable, the comparison in the paper is empowered by a policy shock…
The central concern in ref. 1 that the "timing of the policy shock is incorrect for key regions" is false. We received confirmation from the Ministry of Environmental Protection's representative who authored the policy document issued on February 27, 2013. We confirmed that by July 1, 2014, in the key…
Klein et al. (1) suggest that defined daily doses (DDDs) are not a perfect outcome measure of antibiotic prescribing, particularly for penicillins (39% of total DDDs in 2015 for broad-spectrum penicillins). We identified the same limitations as illustrated by the results of our study (2), which measured the bias of…
The concept of defined daily doses (DDDs) is rooted in the understanding that to assess drug utilization and to develop rational interventions at the patient level, a common framework for comparing varied sources and forms of drug utilization data are necessary (1–3).

Although among…
Photorespiration recycles ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) oxygenation product, 2-phosphoglycolate, back into the Calvin Cycle. Natural photorespiration, however, limits agricultural productivity by dissipating energy and releasing CO2. Several photorespiration bypasses have been previously suggested but were limited to existing enzymes and pathways that release CO2. Here,
A-kinase anchoring proteins (AKAPs) shape second-messenger signaling responses by constraining protein kinase A (PKA) at precise intracellular locations. A defining feature of AKAPs is a helical region that binds to regulatory subunits (RII) of PKA. Mining patient-derived databases has identified 42 nonsynonymous SNPs in the PKA-anchoring helices of five AKAPs….
The cyanobacterial clock proteins KaiA, KaiB, and KaiC form a powerful system to study the biophysical basis of circadian rhythms, because an in vitro mixture of the three proteins is sufficient to generate a robust ∼24-h rhythm in the phosphorylation of KaiC. The nucleotide-bound states of KaiC critically affect both…
The ubiquitin-like protein ubiquilin 2 (UBQLN2) has been genetically and pathologically linked to the neurodegenerative diseases amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), but its normal cellular functions are not well understood. In a search for UBQLN2-interacting proteins, we found an enrichment of stress granule (SG) components, including ALS/FTD-linked…
Urbanization represents an extreme transformation of more natural systems. Populations of most species decline or disappear with urbanization, and yet some species persist and even thrive in cities. What determines which species persist or thrive in urban habitats? Direct competitive interactions among species can influence their distributions and resource use,…
Intracellular organisms, such as obligate parasites and endosymbionts, typically possess small genomes due to continuous genome decay caused by an environment with alleviated natural selection. Previously, a few species with highly reduced genomes, including the intracellular pathogens Mycoplasma and Microsporidia, have been shown to carry degenerated editing domains in aminoacyl-tRNA…
Mucosa-associated invariant T (MAIT) cells are unconventional innate-like T cells that recognize microbial riboflavin metabolites presented by the MHC class I-like protein MR1. Human MAIT cells predominantly express the CD8α coreceptor (CD8+), with a smaller subset lacking both CD4 and CD8 (double-negative, DN). However, it is unclear if these two…
The SMCR8-WDR41-C9ORF72 complex is a regulator of autophagy and lysosomal function. Autoimmunity and inflammatory disease have been ascribed to loss-of-function mutations of Smcr8 or C9orf72 in mice. In humans, autoimmunity has been reported to precede amyotrophic lateral sclerosis caused by mutations of C9ORF72. However, the cellular and molecular mechanisms underlying…
A subset of midbrain dopamine (DA) neurons express vesicular glutamate transporter 2 (VgluT2), which facilitates synaptic vesicle loading of glutamate. Recent studies indicate that such expression can modulate DA-dependent reward behaviors, but little is known about functional consequences of DA neuron VgluT2 expression in neurodegenerative diseases like Parkinson's disease (PD)….
Fruit growth and ripening are controlled by multiple phytohormones. How these hormones coordinate and interact with each other to control these processes at the molecular level is unclear. We found in the early stages of Fragaria vesca (woodland strawberry) fruit development, auxin increases both widths and lengths of fruits, while…
Resistance (R) genes encode intracellular nucleotide-binding/leucine-rich repeat-containing (NLR) family proteins that serve as critical plant immune receptors to induce effector-triggered immunity (ETI). NLR proteins possess a tripartite domain architecture consisting of an N-terminal variable region, a central nucleotide-binding domain, and a C-terminal leucine-rich repeat. N-terminal coiled-coi
Organic matter is responsible for the generation of hydrocarbons during the thermal maturation of source rock formation. This geochemical process engenders a network of organic hosted pores that governs the flow of hydrocarbons from the organic matter to fractures created during the stimulation of production wells. Therefore, it can be…
Many differential equations involved in natural sciences show singular behaviors; i.e., quantities in the model diverge as the solution goes to zero. Nonetheless, the evolution of the singularity can be captured with self-similar solutions, several of which may exist for a given system. How to characterize the transition from one…
Heterochromatin is a silenced chromatin region essential for maintaining genomic stability and driving developmental processes. The complicated structure and dynamics of heterochromatin have rendered it difficult to characterize.

In a nationally representative survey experiment, diverse segments of the US public underestimated the environmental concerns of nonwhite and low-income Americans and misperceived them as lower than those of white and more affluent Americans. Moreover, both whites and nonwhites and higher- and lower-income respondents associated the term "environmentalist" with whites…
Phylogenetic evidence suggests that the invasion and proliferation of retroelements, selfish mobile genetic elements that copy and paste themselves within a host genome, was one of the early evolutionary events in the emergence of eukaryotes. Here we test the effects of this event by determining the pressures retroelements exert on…
Species richness is greatest in the tropics, and much of this diversity is concentrated in mountains. Janzen proposed that reduced seasonal temperature variation selects for narrower thermal tolerances and limited dispersal along tropical elevation gradients [Janzen DH (1967) Am Nat 101:233–249]. These locally adapted traits should, in turn, promote reproductive…
Biological sex affects adaptive immune responses, which could impact influenza infection and vaccine efficacy.

In 1826, Americans loved to drink, and the young cadets at West Point Academy were no exception. After being forbidden from imbibing everyone's favorite egg-based holiday beverage, West Point cadets would go on to start a riot that lasted into the early hours of Christmas morning. The story behind the Eggnog Riot both offers a glimpse into life in 1826 and the history behind how West Point became
One of a cell's most important responsibilities is to break down and recycle proteins that are no longer needed or endanger the cell. This task is carried out by a cellular nanomachine called the proteasome. Scientists from Scripps Research deciphered how the proteasome converts energy into mechanical motion that untangles and unfolds proteins for destruction. The findings, published in Science, c
research led by York University's Faculty of Health shows that inhibiting a protein within blood vessels stimulates new blood vessel growth, resulting in healthier fat tissue (adipose) and lower blood sugar levels. The findings provide key insight into how improving blood vessel growth could help to mitigate serious health problems that arise with obesity, such as diabetes.
Heavy precipitation recently fell in areas of California that were recently devastated by deadly wildfires such as the Camp Fire and the Woolsey fire.

Thread-like bacteria make cells that no longer have a cell wall under the influence of osmotic stress. A remarkable discovery, since the cell wall serves as a protection barrier for bacteria. It could also help to explain how pathogenic bacteria can hide in our body from our immune system. A team of Leiden researchers led by Dennis Claessen has published this on 4 December in Nature Communications
As the film industry moves more and more toward prioritizing worldwide box office over domestic ticket sales, genres such as dramas and romantic comedies have begun to die out. Major studios, focused on billion-dollar grosses that can move stock needles, mostly make big franchises instead. One of the best examples of that shift is Disney reportedly declining to make a sequel to its 2009 smash hit
Gadgets No present is better than beautiful hair. I have a lot of hair. Seriously, check my credentials. And when you are truly blessed with a rich abundance of follicles, it kind of consumes your life.
In the westernmost reaches of Nunavut, on the Northwest Passage, Inuit hunters have told me some pithy things about climate change. "The land is changing. It isn't climate change. This is part of cycles. Our elders saw this coming."

Knowing which way is up or down is important for all living things. For plants, which grow roots into the soil and flowers above ground, getting this polarization wrong would cause a whole host of problems. In plants, polarization of the entire organism depends on every single cell being polarized. Cell division, however, disrupts polarization. How polarity is reestablished was previously unknown.
Shell middens are archaeological features consisting mainly of the remains of marine animals thrown away near settlements over hundreds or thousands of years. They are the debris of human activity. In Brazil, they are known by the Tupi word sambaqui.
As with most crime, the highest rates of burglary occur in urban communities since large metropolitan areas generally boast more concentrated wealth. Big cities also allow burglars to maintain anonymity and evade authority while offering ample opportunities for discreet disposal of stolen property. Burglars observe their target cities with the careful attention of urban planners, taking note of pu
With rapid efficiency, a mysterious parasite is seeking out and killing a giant species of clam found only in the Mediterranean Sea. Unless scientists can find a way of stopping it soon, they say the mollusk could go extinct.
Researchers from the Singapore University of Design and Technology (SUTD) have engineered a new, inexpensive nanomaterial that has applications ranging from biomolecule detectors to solar energy conversion.

A team of researchers from the University of Exeter and Fera Science Ltd, both in the U.K. has found evidence that implicates the insecticide fipronil as the culprit behind a massive die-off of honeybees in France in the 1990s. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of two insecticides that were thought to be behind the die-offs
While almost 80% of countries say they count agriculture as a possible way of mitigating climate change, the whole of sub-Saharan Africa—2 billion people to be fed by 2050—recognizes the need to adapt agriculture to climate change.
As the number of millionaires and billionaires in the world climbs ever higher , there are a growing number of people who possess more money than they could ever reasonably spend on even the lushest goods. But at a certain level of wealth, the next million isn't going to suddenly revolutionize their lifestyle. What drives people, once they've reached that point, to keep pursuing more? There are s
Over the last decade, an industry has developed that values different aspects of nature in different ways. Its growth has been underpinned by the argument that, in a neoliberal world where the market is the dominant mechanism for distributing scarce resources, those assets that cannot be priced and traded are either undervalued or overlooked. Putting a price on nature allows it to be included in t
This week, educators, students and the public around the world are participating in Computer Science Education Week by organizing and leading one-hour coding tutorials.
Embryonic stem cells (ESCs) are the very definition of being full of potential, given that they can become any type of cell in the body. Once they start down any particular path toward a type of tissue, they lose their unlimited potential. Scientists have been trying to understand why and how this happens in order to create regenerative therapies that can, for example, coax a person's own cells to
From food and biofuels to cosmetics and detergents, palm oil is found in countless products these days. Demand for the oil has surged in the last decade—global usage went from 37 million metric tons in 2006 to 64.2 million in 2016—in part because it is cheap and, for a time, enjoyed a good-for-you reputation.
SpaceX has postponed its cargo launch to the International Space Station until Wednesday after mold was found on food bars for a mouse experiment bound for the orbiting outpost, NASA said.
Medication administration errors leading to death are common with anticoagulants and antibiotics in particular, according to a new study that analyzed incidents reported in England and Wales. The most common error category was omitted medicine, followed by a wrong dose or a wrong strength. In half of the reported incidents, the patient was aged over 75.
New research led by the Hip Implant Prosthesis Study (HIPS) team at the University of Bristol Medical School has shown that small-head (less than 36 mm in diameter) cemented metal-on-plastic hip replacements are the most cost-effective in men and women older than 65 years. For adults younger than 65, small-head cemented ceramic-on-plastic hip replacements are more likely to be cost-effective.

Chudler , Ph.D., is back
Real-world learning experiences, like summer camps, can significantly improve children's knowledge in a matter of just days, a new study suggests. Researchers found that 4- to 9-year-old kids knew more about how animals are classified after a four-day camp at a zoo.It wasn't that children who attended just knew more facts about animals, the researchers noted. The camp actually improved how they or
Is it in our nature to go to war? Should we just accept the fact that humans have this innate tendency and are hardwired to kill members of other groups?
Venice, Italy, has been flooding for centuries. Once just a symptom of the city's location on a series of islands, and its maze of canals, frequent inundation has turned Venice into a cautionary tale of environmental degradation and inevitable submersion. Climate change will assuredly bring similar risk to U.S. coastal communities. Venice offers an early warning: Some fear that the city will inev

Big data from archaeological sites located in the extreme south of Patagonia have been used for this study.
Learning how to read may have some disadvantages for learning grammar. Children who cannot read yet often treat multiword phrases as wholes ("how-are-you"). After learning to read, children notice individual words more, as these are separated by spaces in written language ("how are you").
Why do people go to war when the consequences of warfare are so dramatic? Scholars have suggested that the motivations for participating in war either lie in the individual rewards warriors receive (to the victor goes the spoils) or because group members coerce them to participate for fear of punishment. Understanding the factors that motivate warriors to join war parties sheds light on some of th
The pattern of arrangement of atoms in a crystal, called the crystal lattice, can have a huge effect on the properties of solid materials. Controlling and harnessing these properties is a challenge that promises rewards in applications such as novel sensors and new solid-state devices.

In Wisconsin and Michigan, Republicans are responding to their loss of top statewide offices in last month's elections by rapidly trying to undercut the Democrats about to take office. The gambit seems straight out of North Carolina, where Republicans used the lame-duck session after the 2016 elections to limit the power of the incoming Democratic governor in what one top Democrat called a "legis
Four new detections of gravitational waves have been announced at the Gravitational Waves Physics and Astronomy Workshop, at the University of Maryland in the United States.
For several years now, commentators have wondered if Democrats—who have shifted left on domestic issues—would shift left on foreign policy, too. We now know the answer; the shift is under way. The clearest evidence yet is the Senate's vote last Wednesday to move forward a bill that would end America's role in the war in Yemen. It signals the birth of a post-Obama Democratic foreign policy. Rememb
It was the only time I had cried in front of one of my bosses at CBS News. As we sat in my office, door closed, I was struggling to explain why I was uncertain whether to sign a new three-year contract with the network. Yes, I could stay on as a general-assignment correspondent, but that would mean being ready and willing to leave town at a moment's notice to cover whatever breaking news was unfo
Freedom is speech is being eradicated on college campuses in favor of identity politics and "snowflake" culture. Rather than be open to new ideas, differing opinions that might make students "feel bad" are shut out. This creates a cycle of negativity between not only the colleges and the students but also the very idea of college being a place of higher learning. The Coddling of the American Mind

This fall, U.S.-led coalition forces escalated attacks in Syria once more, launching more than 1,000 air and artillery strikes , nearly all of them close to the border with Iraq, as Washington seeks to crush the Islamic State's presence in the country before the end of the year. "They're either here to fight to death or they're just going to get killed because they have nowhere to go," the coalit
In my six decades in public service, I've seen many changes in our nation and its institutions. Yet the most profound change I've witnessed is also the saddest. It is the complete collapse in respect for virtually every institution of government and an unprecedented cynicism about the nobility of public service itself. These are not just the grumblings of an angry old man lamenting the loss of "t
It could have been worse. Responding to the death of George H. W. Bush, with whom he had a slow-simmering feud , President Donald Trump avoided taking a swipe, and instead paid his respects to his Republican predecessor. Still, the president's remarks to reporters in Argentina, where he was traveling for the G20 summit, were peculiar. "He was a very fine man. I met him on a number of occasions,"

Archaeologists say man who died 500 years ago may have been a mudlark or fisherman He was found lying on his front, head twisted to the side. One arm was bent above his head, suggesting he had fallen – or perhaps had been pushed – to his death in the river more than five centuries ago. But aside from his puzzling position, the skeleton discovered this year near the shore of the Thames in London w
