A new report assesses the values emphasized by television programs popular with tweens over each decade from 1967 to 2017, charting how 16 values have waxed and waned during those 50 years. How important is fame? Self-acceptance? Among the findings: Fame, after nearly 40 years of ranking near the bottom (it was 15th in 1967, 1987 and 1997), rose to the No. 1 value in 2007, then dropped to sixth in...

Researchers published findings that blight leads to an increased abundance of disease-carrying mosquitoes. The researchers investigated the presence of several mosquito species in two adjacent but socio-economically contrasting neighborhoods in Baton Rouge: the historic Garden District, a high-income neighborhood, and the Old South neighborhood, a low-income area.

An important Maya man buried nearly 1,300 years ago led a privileged yet difficult life. The man, a diplomat named Ajpach' Waal, suffered malnutrition or illness as a child, but as an adult he helped negotiate an alliance between two powerful dynasties that ultimately failed. The ensuing political instability left him in reduced economic circumstances, and he probably died in relative obscurity,...

Scientists found frozen plant fossils, preserved under a mile of ice on Greenland. The discovery helps confirm a new and troubling understanding that the Greenland Ice Sheet has melted entirely during recent warm periods in Earth's history -- like the one we are now creating with human-caused climate change. The new study provides strong evidence that Greenland is more sensitive to climate change...

Researchers have pinpointed what causes normal proteins to convert to a diseased form, causing conditions like CJD and Kuru.

The ocean, a longtime reservoir for CFC-11, will become a source of the ozone-depleting chemical by middle of next century.

Some invasive species targeted for total eradication bounce back with a vengeance, especially in aquatic systems, finds a new study. The study chronicles the effort -- and failure -- to eradicate invasive European green crabs from a California estuary.

Scientists have harnessed microfluidic organs-on-chip technology to model the different anatomical sections of the mouse intestine and their symbiosis with a complex living microbiome in vitro. In a comparative analysis of mouse and human microbiomes, the researchers were able to confirm the commensal bacterium Enterococcus faecium contributes to host tolerance to Salmonella typhimurium infection....

Increased internet-access spending by Texas public schools improved academic performance but also led to more disciplinary problems among students, a study of 9,000 schools shows.

Scientists were ready to jump at the opportunity to get an unprecedented look at the workings of Steamboat Geyser. Their findings provide a picture of the depth of the geyser as well as a redefinition of a long-assumed relationship between the geyser and a nearby spring.

One day soon, a woman's first trip to the doctor after conceiving may include a prescription for an exercise program.

An international research team has for the first time linked glacier-fed mountain rivers with higher rates of plant material decomposition, a major process in the global carbon cycle.

An AI tool offers new opportunities for analyzing images taken with microscopes. A study shows that the tool, which has already received international recognition, can fundamentally change microscopy and pave the way for new discoveries and areas of use within both research and industry.

Researchers have developed DeepBAR, a machine learning technique that quickly calculates drug molecules' binding affinity with target proteins. The advance could accelerate drug discovery and protein engineering.

If you count yourself among those who lose themselves in the lives of fictional characters, scientists now have a better idea of how that happens. Researchers found that the more immersed people tend to get into 'becoming' a fictional character, the more they use the same part of the brain to think about the character as they do to think about themselves.

Recent summer droughts in Europe are far more severe than anything in the past 2,100 years, according to a new study.

Engineers have developed self-cooling fabrics from polyethylene, commonly used in plastic bags. They estimate that the new fabric may be more sustainable than cotton and other common textiles.

Using NASA satellite images and machine learning, researchers have mapped changes in the landscape of northwestern Belize over a span of four decades, finding significant losses of forest and wetlands, but also successful regrowth of forest in established conservation zones that protect surviving structures of the ancient Maya.

A home-based parenting program to prevent childhood behavior problems, which very unusually focuses on children when they are still toddlers and, in some cases, just 12 months old, has proven highly successful during its first public health trial.

Researchers have now presented results that may change our basic view of how type 2 diabetes occurs. Their study indicates that free fatty acids (FFAs) in the blood trigger insulin release even at a normal blood-sugar level, without an overt uncompensated insulin resistance in fat cells.

Researchers have discovered that heparanase, HPSE, a poorly understood protein, is a key regulator of cells' innate defense mechanisms.

Psychologists have been studying emotional health and well-being for decades, often having people engage in contrived laboratory experiments and respond to self-report questionnaires to understand their emotional experiences and the strategies they use to manage stress. But those hundreds of studies may have missed a pretty big complicating factor - baseline anxiety levels of the subjects --...

Researchers recently captured the first signs of very low-frequency gravitational waves. They analyzed the data and considered the possibility of whether this may point towards new physics beyond the Standard Model. They report that the signal is consistent with both a phase transition in the early universe and the presence of a field of extremely light axion-like particles (ALPs).

A new study suggests that hot, rocky exoplanets could not only develop atmospheres full of water vapor, but keep them for long stretches.
