Study provides insight into how we sense threats in our environment

Researchers at the University of Toronto have shown that our ability to quickly assess threats in our environment comes from our perception of discrete linear features in a scene rather than details or objects within it.

National security officials warn that worsening heat waves, droughts and other climate-fueled hazards are likely to drive a surge in global migration in the coming decades, increasing political instability among the United States' allies and strengthening its adversaries.

Novel advanced light design and fabrication process could revolutionize sensing technologies

Vanderbilt and Penn State engineers have developed a novel approach to design and fabricate thin-film infrared light sources with near-arbitrary spectral output driven by heat, along with a machine learning methodology called inverse design that reduced the optimization time for these devices from weeks or months on a multi-core computer to a few minutes on a consumer-grade desktop.

New material could pave way for better, safer batteries

Now, a research team from Brown University and the University of Maryland has developed a new material for use in solid-state batteries that's derived from an unlikely source: Trees.

Biodiversity of islands worldwide is in peril, scientists warn

Scientists are sounding the alarm. The biodiversity of islands around the world is becoming increasingly threatened, due in large part to habitat loss, overexploitation, invasive species and climate change. If healthy island environments are to be conserved and restored, immediate action is needed by everyone, from policymakers to the general population. These findings and recommendations are in "Scientists' warning—The outstanding biodiversity of islands is in peril," published in Global Ecology and Conservation in September 2021 and co-authored by a University of Hawaiʻi at Mānoa professor.

Climate tipping might be predicted using algebraic topology

The Earth's climate system seems to have shifted abruptly between colder and warmer modes in the past. Do we risk the same today from anthropogenic climate change? Frankly, climate models cannot answer that question yet. But a result in the journal Chaos by Gisela D. Charó, Mickaël D. Chekroun, Denisse Sciamarella and Michael Ghil suggests a way to resolve the matter. Analyzing a model that combines the two leading theories for climate change with algebraic topology tools, the authors show that the climate system indeed progresses through abrupt transitions, also known as tipping points. These tools are applicable to reduced climate models and they well might help assess whether the Earth's climate system on a whole is about to tip due to global warming. The work is part of the TiPES project, a European science collaboration on tipping points in the Earth system.

Artificial intelligence spots anomalies in medical images

Scientists from Skoltech, Philips Research, and Goethe University Frankfurt have trained a neural network to detect anomalies in medical images to assist physicians in sifting through countless scans in search of pathologies. Reported in IEEE Access, the new method is adapted to the nature of medical imaging and is more successful in spotting abnormalities than general-purpose solutions.

Researchers map neurons in the brain involved with social interactions with others in groups

Meaningful social interactions are critical to an individual's well-being, and such interactions rely on people's behaviors towards one another. In research published in Science, investigators at Massachusetts General Hospital (MGH) have mapped the neurons in the brain that allow a monkey to process and remember the interactions and behaviors of another monkey to influence the animal's own actions. The findings might be used to develop treatment strategies for people with neuropsychiatric conditions.

How a deadly land fungus began killing marine mammals in the Salish Sea

In the early 2000s, a fungus infected hundreds of animals and people in British Columbia and Washington State. Scientists found that the disease also killed porpoises and dolphins in the Salish Sea—perhaps affecting cetaceans even earlier than people.

Study shows COVID vaccine booster increases antibody responses, is protective in rhesus macaques

A booster dose of the mRNA-1273 COVID-19 vaccine given to rhesus macaques about six months after their primary vaccine series significantly increased levels of neutralizing antibodies against all known SARS-CoV-2 variants of concern, according to a new study from National Institutes of Health scientists and colleagues. The study, published in Science, also showed that the increased neutralizing antibody responses were sustained for at least eight weeks after the boost, were significantly higher than after the primary vaccine series, and generated high-level protection—meaning the ability to significantly limit virus from replicating in the lungs and nose. These data suggest that boosting triggers a strong immune memory response and potentially longer lasting immunity.

Fighting viruses with interchangeable defense genes

Bacterial viruses, so-called phages, destroy bacteria. Bacteria are constantly exposed to viral attacks. A research team led by Martin Polz, a microbiologist at the University of Vienna, has now studied how bacteria defend themselves against viral predators. The study shows that bacteria have exchangeable genetic elements that are specifically designed for defense against viruses, allowing a bacterial population to switch its innate immunity surprisingly quickly. The question of how and how quickly bacteria develop resistance to viruses is of central importance for the development of phage-based therapies against bacterial infections. The study now appears in the journal Science.

Hubble Space Telescope gives unprecedented, early view of a doomed star's destruction

Like a witness to a violent death, NASA's Hubble Space Telescope recently gave astronomers an unprecedented, comprehensive view of the first moments of a star's cataclysmic demise. Hubble's data, combined with other observations of the doomed star from space- and ground-based telescopes, may give astronomers an early warning system for other stars on the verge of blowing up.

What drove the invention of military technologies?

Peter Turchin from the Complexity Science Hub Vienna (CSH) and an interdisciplinary team of colleagues set out to test competing theories about what drove the evolution of war machines throughout world history. Their study, published today in the journal PLOS ONE, sees the strongest influence on the evolution of military technology coming from world population size, the connectivity between geographical areas, and advances in critical technologies such as iron metallurgy or horse riding. Conversely, and somewhat surprisingly, state-level factors such as the size of the population, the territory, or the complexity of governance seem not to have played a major role.

Zapping untreated water gets rid of more waterborne viruses

Using sophisticated microscopy and computational analysis, Texas A&M University researchers have now validated the merit of a water purification technology that uses electricity to remove and inactivate an assortment of waterborne viruses. They said the yet-to-be-implemented water purification strategy could add another level of safety against pathogens that cause gastrointestinal ailments and other infections in humans.

'Like a magic trick,' certain proteins pass through cell walls

For decades, scientists have wondered how large molecules such as proteins pass through cell walls, also known as plasma membranes, without leaving a trace. That ability is part of what makes certain drugs—including some cancer treatments and the COVID-19 vaccine—work. And it is also how bacterial toxins enter human cells and wreak havoc.
