Flies that cannot take to the air respond by sleeping more as they learn to adapt to their flightlessness, according to a study from Washington University School of Medicine in St. Louis. The findings, published May 8 in Science Advances, suggest that sleep may be an evolutionary tool that helps animals adapt to challenging new situations.
Most everyone knows that humid heat is harder to handle than the "dry" kind. And recently, some scientists have projected that later in the century, in parts of the tropics and subtropics, warming climate could cause combined heat and humidity to reach levels rarely if ever experienced before by humans. Such conditions would ravage economies, and possibly even surpass the physiological limits of...
Epithelial cells are held together and connected by several different types of structures that form cell-cell contacts. One of these structures, found near the top surface of the cell, is the adherens junction. This junction is critical for organ development, tissue architecture and cell function; disruption of adherens junctions can lead to inflammatory bowel disease, disorders of the skin and...
A new study has found that stroke evaluations fell by nearly 40 percent during a period of the COVID-19 pandemic, suggesting that many stroke patients are not seeking potentially life-saving medical treatment.
A new global simulation model offers the first long-term look at how urbanization -- the growth of cities and towns -- will unfold in the coming decades. The research team projects the total amount of urban areas on Earth can grow anywhere from 1.8 to 5.9-fold by 2100, building approximately 618,000 square miles.

Deforestation in the Brazilian Amazon hit a new high in the first four months of the year, according to data released Friday, a worrying trend after the devastation caused by record fires last year.
The chance to put biodiversity and the environment at the heart of recovery from the pandemic should not be squanderedOne night in April, birdwatchers from around Britain stepped outside their doors and listened intently to something most of them had never experienced before: the fluting, mysterious, melancholy cry of the common scoter on the wing.Flocks of these dusky sea ducks were beating their...
New research has demonstrated that the key to implementing successful reform in low-performing schools is hiring and retaining effective principals and teachers. These findings, reported in Educational Evaluation and Policy Analysis (EEPA), also note that teacher turnover as well as student mobility and chronic absenteeism undermine potentially positive effects from these reforms.
A new paper identifies the critical need for research on the ability of the COVID-19 virus to infect certain animal species, the transmissibility of infection between humans and those animals, and the impact infection could have on food security and the economy. The article, which focuses on companion animals, livestock and poultry, working animals such as military service dogs, and zoo species,...
In many fish species body size plays an important role in sexual selection. Large individuals are preferred mating partners because they can enhance offspring survival by providing better quality resources than small individuals. While large females and males are often favored by sexual selection, fishing targets and removes these reproductively superior individuals. Academy Research Fellow Silva...
Evidence continues to mount that the Neandertals, who lived in Europe and Asia until about 40,000 years ago, were more sophisticated people than once thought. A new study from UC Davis shows that Neandertals chose to use bones from specific animals to make a tool for specific purpose: working hides into leather.
The Monte Conca cave system on the island of Sicily is a vast system of springs and pools, sitting below a nature preserve. It might be presumed to be one of the few places untouched by human-driven pollution.
Researchers at ARCNL and Vrije Universiteit Amsterdam have developed a compact setup for fast, super-resolution microscopy through an ultrathin fiber.
