Fish sticks may be a tasty option for dinner, but are they good for the planet? A new study of the climate impacts of seafood products reveals that the processing of Alaskan pollock into fish sticks, imitation crab, and fish fillets generates significant greenhouse gas emissions.
Less active babies may accumulate more fat, which in turn may put them at risk for obesity later in life, a new study shows. Researchers tracked the physical activity levels of 506 infants using small ankle-worn accelerometers for four days per tracking period at ages 3, 6, 9, and 12 months. For each tracking period after 3 months, average physical activity increased by about 4%, in line with inf
The cause of the end-Cretaceous mass extinction is vigorously debated, owing to the occurrence of a very large bolide impact and flood basalt volcanism near the boundary. Disentangling their relative importance is complicated by uncertainty regarding kill mechanisms and the relative timing of volcanogenic outgassing, impact, and extinction. We used carbon cycle modeling and paleotemperature recor

Infections are a dreaded threat that can have fatal consequences after an operation, in the treatment of wounds, and during tissue engineering. Biomimetic hydrogels with 'built-in' antimicrobial properties can significantly decrease this danger. In the journal Angewandte Chemie, scientists have now introduced a gel that is activated by red light to produce reactive oxygen compounds that effectivel
for derivation of an added benefitThe small studies on the histology-independent use of the inhibitor have no controls. The amount of other data is also still too small to assess an added benefit.
A novel micromotors with obvious structural color was proposed by Professor Yuanjin Zhao, et al. By using functional hydrogel to replicate the structure of photonic colloid clusters which was fabricated through rapid solvent extracting of the droplet templets, structural color barcode micromotors were obtained. And it's indicated that the novel micromotors could not only realize multiplex biosensi
A new study shows that there is a huge disproportion in the level of funding for social science research into the greatest challenge in combating global warming — how to get individuals and societies to overcome ingrained human habits to make the changes necessary to mitigate climate change.
According to received wisdom, local activism against the establishment of industrial plants follows a cycle, with its highest intensity a short time after mobilization. If a firm stands, activism fades. New research by Fabrizio Perretti and Alessandro Piazza in Strategic Management Journal analyzes the American anti-nuclear movement and finds that the strategic decisions made by a firm affect both
Smart Vision A startup called Mojo Vision unveiled a working prototype today of what it claims to be "the world's first true smart contact lens." The smart lens is essentially a miniaturized display that you can wear in your eye. The company says it could provide directions, sports scores, or even let them see in the dark . "People can't tell you are wearing it, so we want the interaction to be s
Quick: What's the most common word in the English language that does not appear anywhere in the U.S. Constitution? The answer is a revealing one: she . Presidents, senators, and representatives are always designated as "he." Even the Nineteenth Amendment, which gave women the right to vote, simply bans abridgment of that right "on account of sex." That resolutely masculine language will not chang
Have you ever been to the theater, looked around, and thought about how predominantly white the audience is? Does the same impression come to mind when visiting museums? If it does and the answer is a resounding yes, then you're not alone. There is a major problem in Britain's cultural industry and it's time we all took a hard look at why.
Researchers have harnessed the power of a type of artificial intelligence known as deep learning to create a new laser-based system that can image around corners in real time. With further development, the system might let self-driving cars 'look' around parked cars or busy intersections to see hazards or pedestrians.
Violence against women and girls in South Africa is now recognized as a national crisis. Far too many women and girls experience violence, primarily from their intimate partners.
Hollywood makes bad movies all the time. Sometimes they're highly enjoyable pieces of schlock that divert your attention for 90 minutes before vanishing from memory. Sometimes they're unwatchable slogs, similarly not worth remembering. Then there are the debacles of the release calendar: genuine catastrophes such as Dolittle , the likes of which are rarer than a talking dragonfly. The newest adap
Extinction, or the disappearance of an entire species, is commonplace. Species have been forming, persisting and then shuffling off their mortal coil since life began on Earth. However, evidence suggests the number of species going extinct, and the rate at which they disappear, is increasing dramatically.
A team of researchers affiliated with a large number of institutions in Japan has found a possible link between primitive archaea and the development of eukaryotes. In their paper published in the journal Nature, the group describes culturing Prometheoarchaeum syntrophicum samples and what they learned by studying them.
Intel's NUC9 Extreme Kit shoves a full-fledged gaming PC into a console-like box. (Intel /) Building a gaming PC can be part of the fun—if you know what you're doing.

Every day, roughly 60 percent of all market trades are made by computer. When the market turns volatile, this can climb to as high as 90 percent. Robo-advisors are increasingly making this process available to the consumer, saving them time and money as a result. With humans no longer in the transaction chain, fees are slashed. Undercutting the typical 2 percent cut of profits (not to mention 20
A new study sheds fresh light on how melanoma cells interact with other cells via extracellular vesicles they secrete. The researchers found that extracellular vesicles secreted by melanoma cells use the so-called hedgehog signalling pathway to intensify the malignant properties of the cells they are targeting. The discovery can help in the development of better treatment and diagnostics for melan
The blue monkeys painted on the walls of Akrotiri on the Greek island of Santorini are among many animals found in the frescoes of this 3,600-year-old city. Historians have studied the murals for decades since they were unearthed in the 1960s and 1970s on the island, which was once known as Thera. But when we and a team of other primatologists recently examined the paintings, we realized the monke

Diagnosing EVALI–the e-cigarette, or vaping, product use associated lung injury illness that's recently garnered national attention–can be challenging. Initial symptoms may resemble pneumonia or go unrecognized, according to case analysis in the Journal of the American College of Emergency Physicians (JACEP) Open, a new open access journal.
The giant squid is an elusive giant, but its secrets are about to be revealed. A new study led by the University of Copenhagen has sequenced the creature's entire genome, offering an opportunity to throw some light on its life in the depths of the sea.
A study led by NTU Singapore suggests that Asian parents with terminally ill children found tend to defer discussing their psychological pain with their spouses to protect them from emotional distress. Instead, they prefer to revealed the parents' preference to support each other in pragmatic and solution-oriented ways such as discussing treatment options, arranging care plans and sharing caregivi
Solar-to-fuel conversion offers a promising technology to solve energy problems, yet device performance could be limited by undesired sunlight absorption. Researchers show copper thiocyanate can assist hole transport in oxide photoelectrodes and enable a 4.55% solar-to-hydrogen efficiency in tandem devices.
A host of disease-causing viruses called arenaviruses lurk in animal populations in various parts of the world, sometimes crossing over into humans. When they do cross over, they can be lethal, and only very few treatments exist. Researchers led by scientists at the Weizmann Institute of Science have now devised a clever decoy for these viruses that may keep them from spreading in the body.

The Rosalind Franklin rover of the joint ESA-Roscosmos ExoMars mission completed a series of environmental tests at the end of 2019 at Airbus, Toulouse, France. This included final thermal and vacuum tests where the Rover is heated and cooled to simulate the temperatures of its journey through space and on the surface of Mars. For example, Rosalind Franklin can expect temperatures dropping to –120
In terms of space organization, DNA has powers rivaling Marie Kondo. A strand of DNA that is two meters long intricately folds itself into a cell nucleus only 10 microns across. (One of the hairs on your head has a diameter of 100 microns, and you can't see anything smaller than that without a microscope.) Everything that needs to happen biochemically for the DNA to function hinges upon the precis
Scientists working in medical research, biology, cellular studies, and in understanding bacteria and other pathogens often need to know about temperature rises and falls in the systems on which they focus. Many processes involve heat production and tracking those changes can get to the core of understanding a process, diagnosing a disease or perhaps investigating whether a pharmaceutical, such as
Approximately 7% of patients seeking abortion at Texas clinics had tried to end their current pregnancy on their own before coming to the clinic, research finds. This is higher than the national rate of 2.2%. Patients in the study mentioned four primary reasons for attempting to self-manage their abortion: they could not afford to get to a clinic or pay for the procedure; their local clinic had c

Once upon a time, there was a company named Wyze that made cheap security cameras and other various IoT products. As of today, Wyze cameras won't detect people anymore. People detection, to be clear, is a major feature of Wyze cameras. The Wyze Cam is advertised as offering "custom zone detection and sensitivity settings," and you automatically get a clip of what the camera captures while the ful
Wildfire smoke regularly threatens air quality over vast regions of places like California. But a new study finds a network of low-cost sensors placed in private homes could paint a more detailed picture of localized pollution, especially in areas where data on air quality is limited.
The recent bushfires in Australia have been terrifying. As we talk of firenadoes and megablazes, we're understanding just how dangerous and unpredictable fire behavior can be.
The most diehard NFL fans have already seen their seasons come to an end. This has nothing to do with whether their hometown team made the playoffs and everything to do with the annual exercise in humility known as fantasy football.
Early morning blue light exposure therapy can aid the healing process of people with mild traumatic brain injury, according to new research. "Daily exposure to blue wavelength light each morning helps to re-entrain the circadian rhythm so that people get better, more regular sleep. This is likely true for everybody, but we recently demonstrated it in people recovering from mild traumatic brain in
For the first time, scientists have sequenced and annotated the genome of a giant squid, which shed light on its life in the depths of the sea. Sailors' yarns about the Kraken, a giant sea-monster lurking in the abyss, may have an element of truth. In 1857, the Danish naturalist Japetus Steenstrup linked the tall tales of ships being dragged to the ocean floor to the existence of the giant squid
What researchers have learned about how a sea star accomplishes movement synchronization, given that it has no brain and a completely decentralized nervous system, might help us design more efficient robotics systems.
Concussion can have lifelong consequences and children are particularly at risk The death in 2002 of the former England and West Bromwich Albion striker Jeff Astle from degenerative brain disease placed the spotlight firmly on the possibility of a link between heading footballs and the risk of dementia. The coroner at the inquest ruled that Astle, 59, died from an "industrial disease" brought on
Figuring out an unusual natural product's activity can be a difficult but rewarding exercise. Deep evolutionary time has provided us with a bizarre range of chemical structures that are presumably not being synthesized by organisms for the sheer fun of it – these things are acting as signaling molecules, antifeedants, poisons for the competition, pheromones and who knows what else. Many biochemic

Recently, the research teams from Tongji University and The Hong Kong Polytechnic University demonstrate that a compact broadband acoustic absorber can be achieved with coherently coupled 'weak resonances' (resonant sound absorbing systems with low absorption peaks).
The common guillemot (known as the common murre in North America) breeds in both the Pacific and the Atlantic and is among the most abundant seabirds in the northern hemisphere. But like many other seabirds, its numbers have declined over the last few decades. Part of that decline is due to the marine environment—a seabird's home and hunting ground—becoming increasingly unpredictable and difficult

A 1966 speech by Dr. Martin Luther King, Jr in North Carolina—and the KKK's response—have largely faded from record. Jason Miller, an English professor at North Carolina State University, is the curator of an on-campus photography exhibit about the historical event. (Credit: NC State) We tend to gloss over 1966 and 1967 in our considerations of Dr. King, Miller says, skipping from the March on Wa
Like a G Researchers from the University of California, Los Angeles, have identified a new type of astronomical object in our galaxy — and they appear to shape shift. They're called G objects, and so far, astronomers have identified six of them orbiting the supermassive black hole at the center of the Milky Way. When the G objects are farthest away from the black hole, they are compact. But when
A newly developed method can detect even low-dose human exposure to microcystins and nodularin in human urine. During harmful algal blooms (HABs), species of cyanobacteria release toxic peptides, including microcystins and nodularin into waterways, impacting wildlife and humans living in these marine environments. These findings are the first to report microcystin concentrations directly from expo
An international research collaboration between the United States and Australia has revealed a promising new drug which could treat high-risk leukemia.
Whooping cough bacteria are becoming smarter at colonising and feeding off unwitting hosts — whether they have been vaccinated or not — strengthening calls for a new vaccine, according to UNSW researchers.
När våra celler bygger proteiner kan mycket gå fel.

Att veta vilken bakterie som orsakar en infektion och vilka antibiotika som fungerar eller inte är mycket vikti
A woman's supply of eggs is finite, so it is crucial that the quality of their genetic material is ensured. New work elucidates a mechanism by which, even before birth, the body tries to eliminate egg cells of the poorest quality.
In a new study conducted in mice, researchers found that tobacco smoke from a hookah caused blood to function abnormally and be more likely to clot and quickly form blood clots. The findings provide new evidence that hookah smoking may not be a safe alternative to cigarettes.
Many medical experts have long believed that women simply 'catch up' to men in terms of their cardiovascular risk, but new research shows for the first time that women's blood vessels age at a faster rate than men's. The findings could help to explain why women tend to develop different types of cardiovascular disease and with different timing than men.
Even if they have no way of identifying them, male chimpanzees form intimate bonds with their fathers, according to a new study of wild chimpanzees in Uganda. In adulthood, male chimpanzees form strong relationships with one another. These bonds can be mutually beneficial—to relieve stress, protect one another, and share food . In the new study, which examines when and with whom these bonds devel
Scientists at Sanford Burnham Prebys Medical Discovery Institute have shown that cells from children with NGLY1 deficiency–a rare disorder first described in 2012–lack sufficient water channel proteins called aquaporins. The discovery was published in Cell Reports and may help explain the disorder's wide-ranging symptoms–including the inability to produce tears, seizures and developmental delay
On a blustery day in October, Andrew Langley and 13 other graduate students headed to the woods to learn to boil water. They were allowed no obvious cooking vessels: no pots, no pans, no bowls, no cups, no containers at all. But they did bring deer hides, which Langley had carefully procured from deer farms. They were to boil water the Paleolithic way. Langley is a doctoral student in archaeology
Global climate change is going to drastically alter the environmental conditions for humans and nature.

On an island famed as Australia's "Galapagos" for its unique and abundant wildlife, rescuers are racing to save rare animals in a bushfire-ravaged landscape.
This is going to be a long struggle, perhaps endless. Antivaxxers have been around since there have been vaccines, for over two hundred years, so there is no reason to expect they are going anywhere. Rather, we need an equally permanent anti-antivaxxer movement (otherwise known as the skeptical movement). After the Disneyland measles outbreak, there has been political pressure to push back agains

In Manhattan, the homeless shelters are full, and the luxury skyscrapers are vacant. Such is the tale of two cities within America's largest metro. Even as 80,000 people sleep in New York City's shelters or on its streets, Manhattan residents have watched skinny condominium skyscrapers rise across the island. These colossal stalagmites initially transformed not only the city's skyline but also th
Amerikanerne vil ikke dele efterretninger med allierede, der bruger Huawei-udstyr i deres 5G-netværk. Sådan lyder truslen mod Storbritannien, der skal træffe en endelig beslutning om, hvorvidt man vil bruge udstyr fra den kinesiske producent. Britiske embedsmænd har allerede sagt, at der ikke vil…
While some scientists search for extraterrestrial life by landing rovers on Mars, launching telescopes into space, and scanning the skies with giant radio dishes, geobiologist Joseph Kirschvink thinks that the first telltale signs of alien life may be sitting on a shelf at NASA's Johnson Space Center, bundled in a Martian rock that conveniently fell to Earth. On the wall of Kirschvink's office at
The primary difficulty of interstellar communication is finding common ground between ourselves and other intelligent entities about which we can know nothing with absolute certainty. This common ground would be the basis for a universal language that could be understood by any intelligence, whether in the Milky Way, Andromeda, or beyond the cosmic horizon. To the best of our knowledge, the laws
The only intelligent life forms we know of reside here on Earth. But that hasn't stopped us from trying to answer the question: "Are we alone?" The search for extraterrestrial intelligence now has an accepted acronym, SETI, and a growing number of interested participants. The odds of galactic company can only be estimated, and a primary tool to predict the number of other civilizations out there
A spacefaring species could easily settle the entire Milky Way given billions of years. Yet the fact is that there is no obvious one in our solar system right now. The supposed inconsistency between these statements is the Fermi Paradox, named for the Nobel Prize-winning physicist who supposedly first formulated it. In a trenchant formulation of the Fermi Paradox, American astrophysicist Michael
Humans are probably not the greatest intelligences in the universe. Earth is a relatively young planet and the oldest civilizations could be billions of years older than us. But even on Earth, Homo sapiens may not be the most intelligent species for that much longer. The world Go, chess, and Jeopardy champions are now all AIs. AI is projected to outmode many human professions within the next few
The most important part of being a writer is feeling that you're not important and that the work you're doing is not about you. "A journalist is someone who is willing to disappoint themselves with the truth." Every piece of journalism has a narrative arc, and that arc is integral to any human storytelling.

A group of researchers in France has lost a 2019 paper in Cell Calcium because one of the authors too, um, a bit too much inspiration for the work from a manuscript he'd reviewed for another publication. The article, "TRPV6 calcium channel regulation, downstream pathways, and therapeutic targeting in cancer," was written by a team … Continue reading
SAN JUAN—Weeks into an ominous pattern of earthquakes, Puerto Rico is still shaking violently. On December 28, what might have been an ordinary holiday week was suddenly interrupted by a mild tremor whose intensity registered at 3.8 on the Richter scale. Mild in itself, it began what geologists call an "earthquake swarm" of more than 1,000 tremors to date. The worst was a 6.4 temblor on January 7
As blazes rage in southern Australia, Indigenous fire-prevention techniques that have sharply cut destructive bushfires in the north are drawing new attention.
Podcasten Stetoskopet undersøger, hvordan en robotassisteret operation foregår, og hvordan fremtiden for robotkirurgi ser ud i det danske sundhedsvæsen.
Nature Communications, Published online: 16 January 2020; doi:10.1038/s41467-019-14098-x Endocrine therapy resistance occurs often in estrogen receptor positive (ER+) breast cancer. Here, the authors find that 3D epigenome remodelling at ER-bound enhancer-promoter interactions is a key mechanism underlying endocrine resistance.
Nature Communications, Published online: 16 January 2020; doi:10.1038/s41467-019-13996-4 Letters are more easily identified when embedded in a word. Here, the authors show that word contexts can enhance letter information in early visual cortex, suggesting that the advantage offered by words occurs already during early perceptual processing.
Nature Communications, Published online: 16 January 2020; doi:10.1038/s41467-019-14220-z Fukutin-related protein (FKRP) catalyses the addition of ribitol-phosphate (RboP) to the O-mannosyl glycan of α-dystroglycan and mutations in FKRP cause dystroglycanopathy. Here the authors provide insights into its oligomerization and recognition of the substrates, CDP-Rbo and the RboP-(phospho-)core M3 glyc
Nature Communications, Published online: 16 January 2020; doi:10.1038/s41467-019-14100-6 In breast cancer the contribution of different genetic variants to disease heritability is complex and not fully understood. Here, the authors present a network-based analysis in 84,567 patients studying ~7.3 million variants, identifying gene modules associated with breast cancer survival.
Nature Communications, Published online: 16 January 2020; doi:10.1038/s41467-019-13987-5 While solar-to-fuel conversion offers a promising technology to produce energy, device components can limit light absorption and reduce performances. Here, authors show copper thiocyanate to assist hole transport in photoelectrodes and enable a 4.55% solar-to-hydrogen efficiency in tandem devices.
Nature Communications, Published online: 16 January 2020; doi:10.1038/s41467-019-14129-7 While metallic glasses are expected to have tunable structures, these have rarely been demonstrated. Here, the authors combine temperature and pressure to show a two-way structural tuning in rare earth-based metallic glasses beyond the nearest-neighbor atomic shells.
Nature Communications, Published online: 16 January 2020; doi:10.1038/s41467-019-14044-x Trapped ion mobility (TIMS)-mass spectrometry with parallel accumulation-serial fragmentation (PASEF) facilitates high-sensitivity proteomics experiments. Here, the authors expand TIMS and PASEF to small molecules and demonstrate fast and comprehensive lipidomics of low biological sample amounts.
– I många fall finns det alternativa resor med lägre klimatpåverkan, som människor upplever som mer eller mindre lika bra som de resor de har gjort med flyg. Detta innebär att det finns en realistisk potential för att minska utsläppen från svenskarnas flygresor med cirka en fjärdedel, säger Erik Lundberg, forskare vid Göteborgs universitet.
A woman's supply of eggs is finite, so it is crucial that the quality of their genetic material is ensured. New work from Carnegie's Marla Tharp, Safia Malki, and Alex Bortvin elucidates a mechanism by which, even before birth, the body tries to eliminate egg cells of the poorest quality.
In a new study conducted in mice, researchers found that tobacco smoke from a hookah caused blood to function abnormally and be more likely to clot and quickly form blood clots. The findings provide new evidence that hookah smoking may not be a safe alternative to cigarettes.

Yesterday's government shake-up in Moscow and the institutional changes Vladimir Putin proposed with it are plainly a response to what Russian observers call "Problem-24." As in 2024—when Putin's current, fourth presidential term expires. In 2024, Putin will turn 72. He will have been in power for 24 years. Because of the toxic investment climate, rife with bureaucratic racketeering and corruptio
I magine: A veteran Democrat with a reputation for bipartisan dealmaking defeats a Republican who complains about voter fraud and crusades against illegal immigration. A GOP legislative leader, recognizing the political ground shifting under him, comes reluctantly to the negotiating table. After months of talks, the two strike a compromise on health care that dramatically expands publicly funded

The Galápagos Islands are home to some of the most unique natural habitats in the world, teaming with species found nowhere else on Earth. But ever since humans set foot there nearly 500 years ago, efforts to study and preserve the islands have been met with attempts to exploit and profit from them too.
Usikkerheden om fremtiden for de europæiske forskere vokser. Hvis briterne forlader EU med et no-deal Brexit, vil det få store konsekvenser for forskningen.
I would imagine someone creates an open source kind of manager-bot or something along those lines like Linux but for administrative duties. I mean proprietary software is potentially possibly as well but who is going to make it? IBM? Oracle? A weird offshoot of Byrd Scooter Technology? My point is, companies could save a lot of money but having an AI run things. And they would never need to worry
A massive experiment that deployed regular police patrols on platforms in the London Underground has shown that four 15-minute patrols a day in some of the capital's most crime-ridden stations reduced reported crime and disorder by 21%.
Ukendte gerningsmænd har forsøgt at udnytte en sårbarhed hos Region Sjælland. Konsekvenserne er endnu ukendte, men flere af regionens hjemmesider er fortsat nede.
Are you Team Kate or Team Meghan? If you're anything like me, you don't want to pick a side—and you don't think there should be "sides" at all. Yet ever since Meghan Markle married Prince Harry, parts of the media have pitted the former actor against her sister-in-law. Where Kate Middleton was once depicted as a dull social climber, she is now presented as the epitome of female virtue : a respect
Scooping waste from a Malaysian river to stop it reaching the sea, a solar-powered barge named the "Interceptor" is the latest weapon in a global battle to rid the world's waters of plastic.
Specialist firefighters have saved the world's last remaining wild stand of a prehistoric tree from wildfires that razed forests west of Sydney, officials said Thursday.
A major experiment introducing proactive policing to Underground platforms finds that short bursts of patrolling create a "phantom effect": 97% of the resulting crime reduction was during periods when police weren't actually present.
