Before you head out for ice fishing, trapping, or any other activity on frozen bodies of water, make sure you plan ahead for this kind of winter crisis and make sure you know exactly what to do if it happens to yo
The new health care practice of 'hotspotting' — in which providers identify very high-cost patients and attempt to reduce their medical spending while improving care — has virtually no impact on patient outcomes, according to a new study led by MIT economists.
A study examined a popular approach that coordinated care for the most expensive patients, and found that the project did not reduce hospital admissions.
Using a genomics strain-tracking bioinformatics tool, researchers investigated whether shared bacterial strains remain stable and resilient to changes in diet or environment after adult twins — who had lived together for decades — began to live apart. The study analyzed two metagenomic sequencing databases from pairs of twins — one for children who were still living together and the other from
By reviewing the psychology behind climate change rejection, a researcher suggests four approaches that can sway climate deniers and help overcome obstacles to implementing solutions.
Researchers have found that although a significant percentage of the American public believed the winner of the November 2016 presidential election would be a woman, people rarely used the pronoun 'she' when referring to the next president before the election.
New digital tools will enable land managers to better adapt to the new reality of large wildfires through analytics that guide planning and suppression across jurisdictional boundaries that fires typically don't adhere to.
The malleability of the brain decreases with age, but scientists have identified certain life experiences that allow the adult brain to rewire. In female mice, hearing the distress cries of mouse pups presents a rewiring opportunity. Whether the mouse learns to respond to the cries depends on agene, Mecp2, that influences neurons in the auditory cortex called parvalbumin.
Scientists have identified synergistic cellular pathways for longevity that amplify lifespan fivefold in C. elegans, a nematode worm used as a model in aging research. The increase in lifespan would be the equivalent of a human living for 400 or 500 years, according to one of the scientists.
Corals depend on their symbiotic relationships with the algae that they host. But how do they keep algal population growth in check? The answer to this fundamental question could help reefs survive in a changing climate. New work indicates how sea anemones, which are closely related to coral, control the size of the algal populations that reside within their tissue.
A study of seven wastewater treatment plants in the Eastern United States points to two treatment methods — granular activated carbon and ozonation — as particularly promising. Each technique reduced the concentration of a number of pharmaceuticals, including certain antidepressants and antibiotics, in water by more than 95%, the scientists' analysis found.
Under Attack Hackers have defaced two more United States websites with pro-Iranian propaganda, according to Motherboard . While the hacks affect little more than the sites' appearances, tensions are running high between Iran and the U.S. due to the American assassination of Iran's top military general Qassim Soleimani and Iran's subsequent attack on military bases in Iraq — and the cyberattacks s

A new Penn Medicine study puts researchers within closer reach of vaccines that can protect infants against infections by overcoming a mother's antibodies, which are known to shut down immune defenses initiated by conventional vaccines. That hurdle largely explains why vaccinations for infectious diseases like influenza and measles not given until six to 12 months of age. Findings from the preclin
Scientists at the MDI Biological Laboratory, in collaboration with scientists from the Buck Institute for Research on Aging in Novato, Calif., and Nanjing University in China, have identified synergistic cellular pathways for longevity that amplify lifespan fivefold in C. elegans, a nematode worm used as a model in aging research. The increase in lifespan would be the equivalent of a human living
The frequently cited claim that e-cigarettes are '95% less risky' or '95% less harmful' than combustible cigarettes is outdated, misleading and invalid — and should no longer be made in discussions on the dangers of vaping, according to an editorial published today in the American Journal of Public Health by six leading experts on e-cigarettes and public health.
A preliminary study by researchers at Uppsala University has found that when young, healthy men were deprived of just one night of sleep, they had higher levels of tau — a biomarker for Alzheimer's disease — in their blood than when they had a full, uninterrupted night of rest. The study is published in the medical journal Neurology.
A clear bedtime that parents consistently stick with can get teens to sleep more, according to a new study. "Greater enforcement of parent-set bedtimes for teenagers aged 14-to-17 are associated with longer sleep duration," says lead author Jack Peltz, an assistant professor of psychology at Daemen College who conducted the study as part of a research appointment in the psychiatry department at t
Was Facebook responsible for the election of Donald Trump in 2016? Trump's campaign says yes. Most of his opposition says yes. And now a ranking executive at Facebook, Andrew Bosworth, says yes.

An isoelectric point is a common way to characterize viruses. However, it's not easy. To improve manufacturing for vaccines and gene therapy, a team uses surface charge to determine the isoelectric point of different viruses. Specifically, they use a single-particle method with atomic force microscopy (AFM).
Most people associate the idea of creatures trapped in amber with insects or spiders, which are preserved lifelike in fossil tree resin. An international research team of paleontologists and biologists has now discovered the oldest slime mold identified to date. The fossil is about 100 million years old and is exquisitely preserved in amber from Myanmar.
Hundreds of deceased donor kidneys, discarded each year after being deemed not suitable under current medical criteria, can be transplanted safely and effectively, according to new research. Based on their findings, the researchers strongly recommend that harvested kidneys with acute kidney injury (AKI) no longer be rejected outright. Accepting those kidneys could bolster efforts to reduce the dr

People who pay more attention to media coverage about President Donald Trump's diet are more likely to view fast food as a socially acceptable meal option, according to a new study. They also are more likely to eat fast food in the near future, according to the study's author Jessica Myrick, associate professor of media studies at Penn State's Donald P. Bellisario College of Communications. While
Heat energy can leap across a few hundred nanometers of a vacuum, thanks to a quantum mechanical phenomenon called the Casimir interaction, researchers report. If you use a vacuum-insulated thermos to help keep your coffee hot, you may know it's a good insulator because heat energy has a hard time moving through empty space. Vibrations of atoms or molecules, which carry thermal energy, simply can
Media coverage is more likely to influence jurors to vote for acquittal than for conviction. This new finding challenges arguments that pretrial publicity is of greater concern to defendants due to their Sixth Amendment right to a fair trial.

Researchers report that a type of biodegradable, lab-engineered nanoparticle they fashioned can successfully deliver a "suicide gene" to pediatric brain tumor cells implanted in the brains of mice. The poly(beta-amino ester) nanoparticles, known as PBAEs, were part of a treatment that also used a drug to kill the cells and prolong the test animals' survival.
Corals depend on their symbiotic relationships with the algae that they host. But how do they keep algal population growth in check? The answer to this fundamental question could help reefs survive in a changing climate.
Extreme climate events are severely affecting communities in the U.S. and around the world. The examples are plenty. Australia is currently burning on a scale never seen before—14.5 million acres scorched, half a billion animals killed and hundreds of thousands of people displaced. Hundreds of fires are still burning out of control.
Live chat tools allow for communication between sellers and buyers. They are popular instruments for e-commerce sites that don't have the advantage of face-to-face communication that brick-and-mortar stores do. New research in the INFORMS journal Information Systems Research says these live chats can actually increase sales and boost profits.

The researchers found that students who smoked had rates of clinical depression that were twice to three times higher than did their non-smoking peers.
Cuttlefish viewing a movie of shrimp through 3D glasses properly positioned themselves to strike the 'prey,' suggesting these cephalopods hunt using a process called 'stereopsis' to calculate depth based on the distance between overlapping images perceived by their left and right eyes. While cuttlefish have been known to possess binocular vision, this is the first
Researchers use 3D glasses, films and food to test whether cuttlefish use stereopsis to find prey There are some questions in science that can only be answered by strapping a pair of 3D glasses to an unsuspecting cuttlefish and setting it loose in an underwater movie theatre. That, at least, was the thinking of a team of researchers who set themselves the task of working out how the marine mollus
A doctor diagnosing a 50-year-old patient based on a blood test taken during the patient's infancy would be unthinkable. Anecdotally speaking, however, that's what scientists have done with corn. Using plant RNA data from 2-week-old corn seedlings, plant biologists and computational mathematicians have shown that farmers and scientists can improve adult crop trait predictions with accuracy that ri
Self-esteem is a valuable resource for undergraduate international students trying to socialize with their domestic counterparts at American universities, but new research suggests that while self-esteem predicts better socialization with domestic students, it is curiously unrelated to how international students socialize with other internationals.
New research provides evidence from Siberian caves suggesting that summer sea ice in the Arctic Ocean plays an essential role in stabilizing permafrost and its large store of carbon.

Exploration is essential for skill acquisition and strongly facilitates cognitive performance. In humans, it is widely known that exploration and later cognitive performance are highly dependent on early social inputs. Here, we aim to shed light on the evolutionary roots of this process by studying the effects of variation in opportunities for social learning on the exploratory tendency of immatu
Creating complex multicellular kidney organoids from pluripotent stem cells shows great promise. Further improvements in differentiation outcomes, patterning, and maturation of specific cell types are, however, intrinsically limited by standard tissue culture approaches. We describe a novel full factorial microbioreactor array–based methodology to achieve rapid interrogation and optimization of t
Impaired mitochondrial dynamics and function are hallmarks of many neurological and psychiatric disorders, but direct screens for mitotherapeutics using neurons have not been reported. We developed a multiplexed and high-content screening assay using primary neurons and identified 67 small-molecule modulators of neuronal mitostasis (MnMs). Most MnMs that increased mitochondrial content, length, a
The global temperature targets of limiting surface warming to below 2.0°C or even to 1.5°C have been widely accepted through the Paris Agreement. However, limiting surface warming has previously been proven insufficient to control sea level rise (SLR). Here, we explore a sea level target that is closer to coastal planning and associated adaptation measures than a temperature target. We find that
The evolution of modular colonial animals such as reef corals and bryozoans is enigmatic because of the ability for modules to proliferate asexually as whole colonies reproduce sexually. This reproductive duality creates an evolutionary tension between modules and colonies because selection operates at both levels. To understand how this evolutionary conflict is resolved, we compared the evolutio
Carbon release through boreal fires could considerably accelerate Arctic warming; however, boreal fire occurrence mechanisms and dynamics remain largely unknown. Here, we analyze fire activity and relevant large-scale atmospheric conditions over southeastern Siberia, which has the largest burned area fraction in the circumboreal and high-level carbon emissions due to high-density peatlands. It is
During El Niño events, increased precipitation occurs over the equatorial central eastern Pacific, corresponding to enhanced convective heating that modulates global climate by exciting atmospheric teleconnections. These precipitation anomalies are projected to shift and extend eastward in response to global warming. We show that this predicted change is caused by narrowing of the meridional span
Through their diet, animals can obtain substances essential for imparting special characteristics, such as toxins in monarch butterflies and luminescent substances in jellyfishes. These substances are typically small molecules because they are less likely to be digested and may be hard for the consumer to biosynthesize. Here, we report that Parapriacanthus ransonneti , a bioluminescent fish, obta
Psoriasis is a common chronic skin disorder characterized by keratinocyte hyperproliferation with altered differentiation accompanied by inflammation and increased angiogenesis. It remains unclear whether the first events that initiate psoriasis development occur in keratinocytes or inflammatory cells. Here, using different psoriasis mouse models, we showed that conditional deletion of Flt1 or Nr
Glutamate dysregulation occurs in multiple sclerosis (MS), but whether excitotoxic mechanisms in mature oligodendrocytes contribute to demyelination and axonal injury is unexplored. Although current treatments modulate the immune system, long-term disability ensues, highlighting the need for neuroprotection. Glutamate is elevated before T2-visible white matter lesions appear in MS. We previously
Three-dimensional supranucleosomal chromatin packing plays a profound role in modulating gene expression by regulating transcription reactions through mechanisms such as gene accessibility, binding affinities, and molecular diffusion. Here, we use a computational model that integrates disordered chromatin packing (CP) with local macromolecular crowding (MC) to study how physical factors, includin
Overnutrition results in adiposity and chronic inflammation with expansion of white adipose tissue (WAT). However, genetic factors controlling fat mass and adiposity remain largely undetermined.

Specific ablation of β-catenin in matu
The repair of DNA double-strand breaks occurs through nonhomologous end joining or homologous recombination in vertebrate cells—a choice that is thought to be decided by a competition between DNA-dependent protein kinase (DNA-PK) and the Mre11/Rad50/Nbs1 (MRN) complex but is not well understood. Using ensemble biochemistry and single-molecule approaches, here, we show that the MRN complex is depe
The camera-type eyes of vertebrates and cephalopods exhibit remarkable convergence, but it is currently unknown whether the mechanisms for visual information processing in these brains, which exhibit wildly disparate architecture, are also shared. To investigate stereopsis in a cephalopod species, we affixed "anaglyph" glasses to cuttlefish and used a three-dimensional perception paradigm. We sho
Normative theories of judgment either focus on rationality (decontextualized preference maximization) or reasonableness (pragmatic balance of preferences and socially conscious norms). Despite centuries of work on these concepts, a critical question appears overlooked: How do people's intuitions and behavior align with the concepts of rationality from game theory and reasonableness from legal sch
While cuttlefish wearing glasses is an unexpected sight, a University of Minnesota-led research team built an underwater theater and equipped the cephalopods with specialized 3-D glasses to investigate how cuttlefish determine the best distance to strike moving prey. Their research revealed cuttlefish use stereopsis to perceive depth when hunting a moving target.

El Niño-Southern Oscillation (ENSO) is the strongest signal in interannual climate variation. El Niño increases the precipitation over the equatorial central-eastern Pacific, which releases more latent heat into the tropical atmosphere and thus drives variations of the global climate system like a heat engine. It has been reported that ENSO-induced precipitation anomalies will shift and extend eas
Some cuttlefish absolutely refuse to wear 3-D glasses. These relatives of squid and octopuses have blimplike bodies that end in a ring of eight arms topped by two prominent eyes. It's not hard to mount a pair of specs in front of those eyes, but a cuttlefish's arms are so dexterous that, if it's displeased with its new accoutrements, it can just yank them off. "And indeed, that happened a lot ,"

Researchers are using tree-ring dating to determine not only when trees were cut down to build historic log buildings in the region but also what the forests were like before European immigrants arrived. This could help researchers shed light on when Native Americans abandoned the area and how their absence altered the landscape.
As a healthy heart ages, it becomes more susceptible to cardiovascular diseases. Though researchers have discovered that relaxin, an insulin-like hormone, suppresses atrial fibrillation (AF), inflammation, and fibrosis in aged rats, the underlying mechanisms of these benefits are still unknown. Researchers discuss how relaxin interacts with the body's signaling processes to produce a fundamental m
It's now possible to predict the traits of adult crops with two-week-old seedlings, report researchers, who say the method's accuracy rivals that of genetic approaches. "Traditional breeding methods take months to years, which can be saved if we can predict the desirable traits just from DNA and RNA without growing them, without having to measure the actual traits directly," says Shinhan Shiu, pr

President Donald Trump's first formal remarks since the targeted killing of Iranian General Qassem Soleimani underscored the strange reality of the moment's crisis: After a chaotic and often terrifying week, it's not clear that anything has changed. "As long as I'm president of the United States, Iran will never be allowed to have a nuclear weapon," Trump said today before he'd even offered a "go
Sitting inside the cavernous Brooklyn auditorium where Senator Elizabeth Warren rallied before 3,000 cheering fans last night, you'd never have known that an Iranian retaliatory strike had brought the United States one step closer to another war in the Middle East. Nor would you have guessed that the candidate that these people had waited, in some cases, more than four hours to see, had recently

Permafrost is ground that remains frozen throughout the year; it covers nearly a quarter of Northern Hemisphere land. The frozen state of permafrost enables it to store large amounts of carbon; about twice as much as in the atmosphere. The rate and extent of future thawing of permafrost, and consequent release of its carbon, is hard to predict from modern observations alone.
The new experiments use standardized methods and video recordings, but some researchers stand by earlier evidence that ocean pH influences coral reef fish's response to predator cues.

With the 2020 elections looming and amid continuing concerns over social media's role in US politics, four top universities have published a comprehensive new report recommending how candidates, tech platforms and regulators can ensure that digital political campaigns promote and protect fair elections.
Flu season is underway in the Northern Hemisphere, sickening millions of people and in rare cases, causing hospitalization or death. The best prevention is a flu shot, but it's not unusual for these vaccines to be less effective than intended. Some researchers suspect that the common practice of producing vaccines in chicken eggs could be partially to blame, according to an article in Chemical & E
Scientific literature abounds with examples of ways in which member diversity can benefit a group — whether spider colonies' ability to forage or an industrial company's financial performance. Now, a newly published mathematical framework substantiates the seemingly counterintuitive observations made by prior scholars: interaction among dissimilar individuals can speed consensus.
A new Johns Hopkins Medicine-led study provides the strongest evidence to date that hundreds of deceased donor kidneys, discarded each year after being deemed not suitable under current medical criteria, can be transplanted safely and effectively.
Patients with kidney failure who actively used an online patient portal to track the status of their health care improved their chances of getting a kidney transplant and shortened their wait times for an operation.
A new study shows that implementing hospital-based palliative care services in New York State reduces treatment intensity at the end of life for hospitalized patients.

An international study led by the University of Granada has found that 9.8% of pregnant women in Andalusia fail to have sufficient check-ups during pregnancy — that is, the number of hospital antenatal appointments they attend is lower than recommended.
A doctor diagnosing a 50-year-old patient based on a blood test taken during the patient's infancy would be unthinkable. Anecdotally speaking, however, that's what Michigan State University scientists have done with corn. Using plant RNA data from 2-week-old corn seedlings, Shinhan Shiu, professor of plant biology and computational mathematics, science and engineering, has shown that farmers and s
A key immune signal has a previously unknown role in turning off the immune system's attack on pancreatic cancer cells, a new study finds. The researchers found that pancreatic tumor cells make and release an immune signaling protein, interleukin-1β (IL-1β). This was shown to reduce anticancer immune responses, which promoted the growth of pancreatic ductal adenocarcinoma or PDA, a form of cancer
During storms in the southwestern US, some rattlesnakes drink rain droplets from scales on their backs. This unusual behavior could help them survive in a desert environment with infrequent rain. Now, researchers have figured out how the nanotexture of scales from these snakes helps them use their bodies to harvest rain. They report their results in in ACS Omega.
To establish a molecular signature of this resistance in ovarian cancer, the authors developed preclinical tumor models of adaptive resistance to chronic anti-VEGF treatment.
Most people associate the idea of creatures trapped in amber with insects or spiders, which are preserved lifelike in fossil tree resin. An international research team of palaeontologists and biologists from the Universities of Göttingen and Helsinki, and the American Museum of Natural History in New York has now discovered the oldest slime mould identified to date. The fossil is about 100 million
Metals (iron, zinc, nickel, cobalt, etc.) participate in numerous enzymatic reactions and are essential nutrients for bacteria. Inside our organism, but these metals are scarcely available, because they are bound to proteins which preserve and transport them to the cells and tissues where they will be used.
Experts from the University of Seville have published a recent study in which they determine that the start of the increase in the verdure of vegetation (equivalent to the start of spring) in Africa is directly connected to the amount of hours of sunshine a day—that is to say, it would be the "photoperiod" which controls this process and not the arrival of the first rains, as was believed until no
Increased freshwater from melting Antarctic ice sheets plus increased wind have reduced the amount of oxygen in the Southern Ocean and made it warmer and more acidic, geoscientists report. Researchers found Southern Ocean waters had changed when they compared shipboard measurements taken from 1990 to 2004 with measurements taken using a fleet of microsensor-equipped robot floats from 2012 to 2019

The US assassination of Iranian general Qassem Soleimani has raised fears of nuclear conflict, but Iran has been on the road to building nuclear weapons for some time
So that was not exactly the Cuban missile crisis. In apparent retaliation for the killing of Iran's top terror commander, Iran fired short-range ballistic missiles in the direction of military bases inside Iraq. The missiles inflicted no casualties on U.S. or allied forces. The truly horrible news seems instead to be an accident: the crash of a Ukrainian Airlines flight to Tehran, which killed al
The scientists pinpointed a small mRNA molecule used by TB bacteria to shut down key engines that drive our immune response. However, they also found a protein signal that removes this mRNA molecule and kick-starts the engines back into gear, providing hope for improved therapies in the future.
A new survey of 1000 meat eaters finds support for the principles of veganism, but suggests most think it is inconvenient, expensive and a sacrifice in terms of taste.

How does your food shop affect the planet? Well, think of it like this—consuming just one egg emits between 260 and 330g of CO₂ to the atmosphere. That's because before that egg can reach your plate, animal feed has to be produced and delivered to the hen that laid it. That hen then needs heating pumped into the shed it shares with the other hens on the farm, and their eggs have to be transported,
Like a long-distance food delivery app with no apparent highway, fungi that associate with shallow-rooted shrubs in the tundra are accessing deep stores of nitrogen being released by thawing permafrost.

Ukraine International Airlines' Boeing 737-800 nåede kun at være i luften få minutter, inden det styrtede ned nær en forstad til Teheran. Flyselskabet melder endnu intet om årsagen til ulykken, der har kostet 176 menneskeliv. Myndighederne i Iran peger derimod på en teknisk fejl på motoren.
Decline comes for us all. Rome fell. The British empire receded. The Romanovs, the Hapsburgs—gone. And on a fog-enshrouded night last weekend in Foxborough, Massachusetts, the most impressive and enduring sports dynasty of the 21st century sputtered to its inevitable end, as the Patriots lost to the Tennessee Titans, 20–13 in a first-round playoff game. If this was Tom Brady's last game as a Patr
Is college worth it? As the cost of American higher education soars, inequality widens, and wages stagnate, millions of Millennials and Gen Zers have asked themselves that question. The answer, at least from economists, has remained a resounding yes . One study found that college graduates earn nearly twice as much as their peers without a college degree. But what if those earnings are no longer
Myths about the bushfires grow online before finding their way into the rightwing press and the mouths of politicians The impacts of the climate crisis are now clearly manifesting in ways beyond rising temperatures. In Australia, the conditions for severe bushfires are occurring far more regularly (hot days, dry land and high winds). And the country is now suffering its most intense bushfire seaso
