Are forest fires a threat to the imperiled Spotted Owl? For years, different groups of scientists assumed so, but a new study turns this assumption on its head. Researchers from the John Muir Project, Pennsylvania State University, and Wild Nature Institute found that these previous studies consistently had a serious methodological flaw: they failed to take into account the impact of post-fire logging on Spotted Owls.

The social science literature has long viewed homophily and network-based job recruitment as crucial drivers of segregation. Researchers at Linköping University and ESADE, Ramon Llull University, now show that this view must be revised. In their Science Advances article, they call attention to a previously unidentified factor, the Trojan horse mechanism, which shows that network-based recruitment can reduce rather than increase segregation levels.

The destructive effects of ocean-bottom trawling are easy enough to imagine from any basic description of the practice. Heavy nets 100 yards wide, equipped with weighted rollers and steel doors, are dragged across the seafloor to scoop up cod, halibut, flounder, rockfish, shrimp and other deep-dwelling prey.

The frequency of natural disasters has soared in recent decades. Total damage topped $210 billion worldwide in 2020. With climate change, the costs attributed to coastal storms will increase dramatically.

Tule elk are treasured creatures in California, and for years, animal rights groups have butted heads with the Point Reyes National Seashore over its practice of keeping elk fenced away from nearby cattle ranches.

Insurer American International Group Inc., railroad company CSX Inc. and electric companies Duke Energy Corp., FirstEnergy Corp. and Entergy Corp. have pledged to report publicly about their influence on climate policy and alignment with the Paris Agreement, according to investors.

Gas power plants overtook lignite coal plants in 2020 to become the European Union's largest single source of emissions from electricity, an analysis of the bloc's Emissions Trading Scheme showed Friday.

A team of researchers from the Austrian Academy of Science's, Austrian Archaeological Institute, and the Hebrew University of Jerusalem's Institute of Archeology, has identified a piece of writing on a shard of pottery unearthed in 2018 at the Lachish archaeological site as the oldest piece of writing ever found in Israel. In their paper published in Cambridge University Press's, Antiquity, the group describes studying the writing and what they learned about it.

In a new report now published on Science, Robby Divine and an interdisciplinary research team at the department of biochemistry, regenerative medicine, and vaccines and infectious disease at the University of Washington U.S. and the School of Medicine, at the Tehran University of Medical Sciences, Iran, conducted computational designs of nanocages to assemble antibodies into precise architectures. During the construction, one structural component formed an antibody or Fc-ligand fusion and the second... Читать дальше...

Since fast radio bursts (FRBs) were first discovered over a decade ago, scientists have puzzled over what could be generating these intense flashes of radio waves from outside of our galaxy. In a gradual process of elimination, the field of possible explanations has narrowed as new pieces of information are gathered about FRBs—how long they last, the frequencies of the radio waves detected, and so on.

For over a year, Americans have been struggling with the challenges imposed on them by the global coronavirus pandemic. While all Americans have struggled, the pandemic has imposed three distinctive sets of burdens on the 64 million Americans living with children under the age of 18.

A team of researchers from Spain, Argentina and France has identified 87 Neanderthal footprints found on an ancient shoreline on the Iberian Peninsula. In their paper published in the journal Scientific Reports, the group describes their study of the footprints and what they learned about them.

A group of Schulich Medicine & Dentistry alumni have authored a thorough roadmap for institutions, government and policy-makers to follow in order to implement a systems-thinking approach to address anti-Black racism in Ontario.

Snow cover in the Alps has been melting almost three days earlier per decade since the 1960s. This trend is temperature-related and cannot be compensated by heavier snowfall. By the end of the century, snow cover at 2,500 meters could disappear a month earlier than today, as simulations by environmental scientists at the University of Basel demonstrate.

Farmers need to be prepared to take action now in order to achieve Net Zero in the agriculture sector by 2050, according to UCL researchers.

A single footprint left by a cat-sized dinosaur around 100 million years ago has been discovered in China by an international team of paleontologists.

Researchers conducting a planned University of Florida-led study on plankton in two lagoons of the Florida Keys stumbled upon an unexpected presence in the course of their routine sampling: microplastics.

The mass shootings in Atlanta and Colorado in March again put a spotlight on gun violence in America and sparked renewed discussion about prevention policy. Despite a global pandemic, 2020 recorded the highest-ever number of civilian lives lost to firearms: Guns were used to kill almost 20,000 Americans by homicide, and 24,000 died in suicides by gun.

Effective assistant principals have the potential to greatly impact a school's success, though they are often underutilized, a new Vanderbilt-led study finds. The report—developed by Peabody College of education and human development faculty Ellen Goldring and Mollie Rubin, and Mariesa Herrmann of Mathematica—also sheds light on the varied functions of assistant principals across the country and suggests ways to better prepare and support them to increase impact on students.

Roughly half the kids in shared households may be living as "guests" in a less stable and secure environment, according to new research from the University of Michigan's Ford School of Public Policy.

A pair of earth scientists at the Indian Institute of Technology–Kanpu are calling for flood prevention and warning systems in areas around the Himalayan mountains to protect people from floods or to warn them of impending disasters. In their Perspectives piece published in the journal Science, Tanuj Shukla and Indra Sen point out that rising temperatures due to global warming are leading to an increase in flood danger for people who live in the area.
