A new study demonstrates how quickly COVID-19 can spread through a household, and provides insight into how and why communities of color have suffered disproportionately from the pandemic.
Robot mimics the powerful punch of the mantis shrimp
- ScienceDaily
- 21/8/25 21:37
Mantis shrimp pack the strongest punch of any creature in the animal kingdom. How mantis shrimp produce these deadly, ultra-fast movements has long fascinated biologists. Now, an interdisciplinary team of roboticists, engineers and biologists have modeled the mechanics of the mantis shrimp's punch and built a robot that mimics the movement. The research sheds light on the biology of these...
Biomarker may help predict benefits of immunotherapy
- ScienceDaily
- 21/8/25 21:37
A group of researchers reported that a specific pattern, or 'signature,' of markers on immune cells in the blood is a likely biomarker of response to checkpoint immunotherapy. Within this immune signature, a molecule LAG-3 provided key information identifying patients with poorer outcomes.

Researchers identify genetic cause of endometriosis and reveal potential drug target
- ScienceDaily
- 21/8/25 20:31
New research offers insight into how to treat endometriosis. The researchers performed genetic analyses of humans and rhesus macaques to identify a specific gene, NPSR1, that increases risk of suffering from endometriosis. The results reveal a potential new nonhormonal drug target that may lead to improved therapy.
Widespread tumor suppression mechanism stops cancer progression by interfering with cancer cell metabolism
- ScienceDaily
- 21/8/25 20:31
A Wistar study shows the tumor suppressor Parkin, whose levels are reduced in different cancer types, causes acute metabolic and oxidative stress, suppresses mitochondrial trafficking, and blocks tumor cell movement, reducing primary and metastatic tumor growth.
Men and women of Roman Herculaneum had different diets, new research shows
- ScienceDaily
- 21/8/25 20:31
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 and locally grown fruit and vegetables while the men dined on more expensive fish.
‘Nanojars’ capture dissolved carbon dioxide, toxic ions from water
- ScienceDaily
- 21/8/25 20:31
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 dioxide later. Now, researchers have developed tiny 'nanojars' that split bicarbonate into carbonate and capture it, as well as certain toxic anions, so...
Exposure to tobacco smoke in early life is associated with accelerated biological aging, study finds
- ScienceDaily
- 21/8/25 20:31
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 finds gender differences in fear and risk perception during COVID-19
- ScienceDaily
- 21/8/25 20:30
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 expectations about health-related outcomes.
Physicists make laser beams visible in vacuum
- ScienceDaily
- 21/8/25 20:30
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. The method makes it easier to perform the ultra-precise laser alignment required to manipulate individual atoms.
Pictograms are first written accounts of earthquakes in pre-Hispanic Mexico
- ScienceDaily
- 21/8/25 20:30
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 studied the country's historical earthquakes.
Scientists turn pollen into 3D printing ink for biomedical applications
- ScienceDaily
- 21/8/25 20:30
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.
Call for healthcare leaders to ensure women and girls have access to safe and affordable menstrual products and health
- ScienceDaily
- 21/8/25 20:30
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, along with the clinicians who serve them.
A game changer: Virtual reality reduces pain and anxiety in children

Randomized clinical trial shows that engaging in virtual reality can significantly reduce pain and anxiety in children undergoing intravenous catheter placement.
Fossils illuminate dinosaur evolution in eastern North America
- ScienceDaily
- 21/8/25 20:30
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 of the eastern United States -- about 85 million years ago: an herbivorous duck-billed hadrosaur and a carnivorous tyrannosaur.
Dams ineffective for cold-water conservation
- ScienceDaily
- 21/8/25 20:30
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.
In hot weather, outdoor laborers work less -- when economy is growing

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.
Central European prehistory was highly dynamic
- ScienceDaily
- 21/8/25 20:30
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 that researchers start to better understand the magnitude, rate and social implications of these changes.
Protecting gardens and crops from insects using the ‘smell of fear’
- ScienceDaily
- 21/8/25 20:29
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 resistant to traditional pesticides, researchers now report they have bottled the 'smell of fear' produced by predators to repel and disrupt insects...
Tropical forests in Africa’s mountains store more carbon than previously thought – but are disappearing fast
- ScienceDaily
- 21/8/25 17:37
An international study found that intact tropical mountain (or montane) forests in Africa store around 150 tons of carbon per hectare. This means that keeping a hectare of forest standing saves CO2 emissions equivalent to powering 100 homes with electricity for one year.
