How polar bears maintained highly specialized diets during periods of Arctic warming—until now
Polar bears are often considered the poster-child species for climate change impacts. With global warming and sea-ice declines, it becomes harder for polar bears to hunt their preferred prey—seals. Increased global temperatures are having the great.....»»
Direct measurement of a subtle current phase relation shows potential for more stable superconducting qubits
In recent years, quantum physicists and engineers have made significant strides toward the development of highly performing quantum computing systems. Realizing a quantum advantage over classical computing systems and enabling the stable operation of.....»»
Electricity-driven catalyst offers climate-neutral methane production
Researchers at the University of Bonn and University of Montreal have developed a new type of catalyst and used it in their study to produce methane out of carbon dioxide and water in a highly efficient way using electricity. Methane can be used, for.....»»
How future heat waves at sea could devastate UK marine ecosystems and fisheries
The oceans are warming at an alarming rate. 2023 shattered records across the world's oceans, and was the first time that ocean temperatures exceeded 1°C over pre-industrial levels. This led to the emergence of a series of marine heat wave events ac.....»»
Study suggests statistical "noise" affects perceived evolutionary rates
For decades, researchers have observed that rates of evolution seem to accelerate over short time periods—say five million years versus fifty million years. This broad pattern has suggested that "younger" groups of organisms, in evolutionary terms,.....»»
Investigating "purist" organizations motivations—can they survive in a world of compromise?
For centuries, the Roncal Valley, in the Navarrese Pyrenees, has pleased the world's palates through the unique cheese that bears its name. The first Spanish cheese to receive Protected Designation of Origin (PDO) status, Roncal owes its signature pi.....»»
Scientists design silver nanoparticle–based self-hygienic resin for use in dental applications
The oral cavity is home to a rich ecosystem of microorganisms that are found in both healthy and diseased states. In the area of dental restoration, highly specialized materials are used to fulfill specific functions so that the patient recovers thei.....»»
Mathematicians and climate researchers build new models for understanding polar sea ice
Polar sea ice is ever-changing. It shrinks, expands, moves, breaks apart, reforms in response to changing seasons, and rapid climate change. It is far from a homogenous layer of frozen water on the ocean's surface, but rather a dynamic mix of water a.....»»
Study: Wildfires will make the land absorb much less carbon, even if warming is kept below 1.5°C
One of the aims of the Paris Agreement was to "pursue efforts" to keep global warming below 1.5°C, but even this ambitious target would not stop the land's ability to absorb carbon weakening as wildfires become fiercer and more frequent, according t.....»»
Climate change is causing algal blooms in Lake Superior for the first time in history
Lake Superior is known for its pristine waters, but a combination of nutrient additions from increasing human activity (including farming and development), warming temperatures and stormy conditions have resulted in more frequent blooms of potentiall.....»»
Supercharged storms: how climate change amplifies cyclones
From Hurricane Helene to Typhoon Yagi, powerful storms are battering the globe, and scientists warn that a warming planet is amplifying their destructive force to unprecedented levels......»»
Decades-long research reveals new understanding of how climate change may impact caches of Arctic soil carbon
Utilizing one of the longest-running ecosystem experiments in the Arctic, a Colorado State University-led team of researchers has developed a better understanding of the interplay among plants, microbes and soil nutrients—findings that offer new in.....»»
15% of office workers use unsanctioned GenAI tools
Rigid security protocols — such as complex authentication processes and highly restrictive access controls — can frustrate employees, slow productivity and lead to unsafe workarounds, according to Ivanti. Understanding workplace behavior key to s.....»»
As temperatures rise, researchers identify mechanisms behind plant response to warming
Microscopic pores on the surface of leaves called stomata help plants "breathe" by controlling how much water they lose due to evaporation. These stomatal pores also enable and control carbon dioxide intake for photosynthesis and growth......»»
Arctic plant study suggests the rate of climate change threatens to exceed the adaptive capacity of species
A research group at the Finnish Museum of Natural History is investigating the adaptive potential of plant species amid a warming climate. Their recent study investigates the Siberian primrose, a plant species that occurs on the coasts of the Bothnia.....»»
Scientists highlight overlooked threats to Arctic coasts amid climate change
As climate change rapidly transforms Arctic marine systems, the dramatic image of a polar bear struggling on a melting ice floe has become symbolic of the region's environmental crisis. But scientists argue that coastal Arctic ecosystems are undergoi.....»»

Study tracks traveling population wave in Canada lynx
A new study by researchers at the University of Alaska Fairbanks's Institute of Arctic Biology provides compelling evidence that Canada lynx populations in Interior Alaska experience a "traveling population wave" affecting their reproduction, movemen.....»»
California governor vetoes controversial AI safety bill
Newsom says SB-1047 ignored "smaller, specialized models" and curtailed innovation. Enlarge / California Governor Gavin Newsom, seen speaking to reporters after September's presidential debate. (credit: Getty Images) Cal.....»»
Cities unprepared for impact of climate change, says report
Half of the world's population lives in cities, and that proportion is expected to increase to 70% by 2050. With their large populations, lack of green spaces that can cool a warming environment, and aging infrastructure that is vulnerable to floods.....»»
Retracing walrus ivory trade of Viking Age reveals early interactions between Europeans and Indigenous North Americans
By examining ancient walrus DNA, an international research team led by Lund University in Sweden have retraced the walrus ivory trade routes of the Viking Age. They found that Norse Vikings and Arctic Indigenous peoples were probably meeting and trad.....»»
