For The Better

Archaeologists examining the Herculaneum skeletal remains of the victims of Vesuvius say they have helped shed new light on the eating habits of ancient Romans — with food differentiated along gender lines and revealing women ate more animal products …

Carbon dioxide from the atmosphere dissolves in waterways, forming bicarbonate ions and other compounds that change water chemistry, with possible harmful effects on aquatic organisms. In addition, bicarbonate can reenter the atmosphere as carbon dioxi…

A new study analyzes the association between more than 100 environmental exposures and the ‘epigenetic clock’ of over 1,000 children in six European countries.

Researchers have developed a method to engineer new functionalities into cells.

New research suggests that men and women worry about the impact of COVID-19 in far different ways. For example, men are more likely to be concerned about financial consequences from COVID-19 while women report greater fear and more negative expectation…

A beam of light can only be seen when it hits matter particles and is scattered or reflected by them. In a vacuum, however, it is invisible. Physicists have now developed a method that allows laser beams to be visualized even under these conditions. Th…

The Codex Telleriano Remensis, created in the 16th century in Mexico, depicts earthquakes in pictograms that are the first written evidence of earthquakes in the Americas in pre-Hispanic times, according to a pair of researchers who have systematically…

Scientists have found a way to use sunflower pollen to develop a 3D printing ink material that could be used to fabricate parts useful for tissue engineering, toxicity testing and drug delivery.

A new commentary reinforces the need to engage the public in understanding the importance of menstrual health. This includes sufficient funding and more research to educate young people, their parents and communities about the process of menstruation, …

Randomized clinical trial shows that engaging in virtual reality can significantly reduce pain and anxiety in children undergoing intravenous catheter placement.

Tyrannosaurus rex, the fearsome predator that once roamed what is now western North America, appears to have had an East Coast cousin. A new study describes two dinosaurs that inhabited Appalachia — a once isolated land mass that today composes much o…

Knowing where cold water is likely to stay cold is critical for conservation. But “cold” is more than just a number on a thermometer. Dams do not adequately support cold-water ecosystems, finds a new study.

A new analysis suggests that U.S. workers in industries that expose them to weather conditions work fewer hours per day when temperatures surpass 90 degrees Fahrenheit — but only during periods of economic growth.

Recent archaeogenetic studies have shown that human movements like migrations and expansions played a major role in driving the spread of cultures and genes in ancient Europe. However, it is only now with detailed regional studies and dense sampling th…

For home gardeners and farmers, herbivorous insects present a major threat. The predator insects that feed on these bugs emit odors that pests can sense, which changes the pests’ behavior and physiology to avoid being eaten. With bugs becoming more res…
