Introducing additives to concrete manufacturing processes could reduce the sizeable carbon footprint of the material without altering its bulk mechanical properties, a study shows.

Is the eye a window into aging? New research has shown how imaging of the fundus, the blood vessel-rich tissue in the retina, can be used to track human aging, in a way that is noninvasive, less expensive and more accurate than other aging clocks that are currently available. Researchers also did a genome-wide association study (GWAS) to establish the genetic basis for such a clock, which they...

Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.

Colorful particles of plastic drift along under the surface of most waterways. These barely visible microplastics -- less than 5 mm wide -- are potentially harmful to aquatic animals and plants, as well as humans. Now, a team reports a two-stage device made with steel tubes and pulsing sound waves that removes most of the plastic particles from real water samples.

The ancient art of origami is well known for transforming sheets of paper and other foldable materials into complex 3D shapes. But now, chemical engineers have extended the centuries-old practice to produce intricate shapes made of glass or other hard materials. Their thoroughly modern method, which can be combined with 3D printing, could have applications ranging from sculpture to catalysis and...

Researchers discover that actin acts in the cell nucleus and is partly responsible for the expression of male sexual characteristics.

New research in mice suggests that 'dormant' cone photoreceptors in the degenerating retina are not dormant at all, but continue to function, producing responses to light and driving retinal activity for vision.

Solving the climate crisis and biodiversity crisis are not separate issues. Animals remove billions of tons of carbon dioxide each year. Restoring species will help limit global warming, new science reveals.

For the first time, researchers have developed a form of the omega-3 fatty acid docosahexaenoic acid (DHA) that is capable of crossing into the eye's retina to ward off visual declines related to Alzheimer's disease, diabetes and other disorders.

Engaging communities in developing a real-time early warning system could help to reduce the often-devastating impact of flooding on people and property -- particularly in mountainous regions where extreme water events are a 'wicked' problem, a new study reveals.

Growing concerns over the potential health effects of exposure to phthalates have led to a search for safer alternatives. Researchers found that the chemical acetyl tributyl citrate (ATBC) might not be the best replacement.

Sleep scientists' analyses show associations between early classes, less sleep, poor attendance and reduced grade point average. Studies in secondary and junior college students have shown that later start times can have positive impacts on grades.

Cancer-associated fibroblasts (CAFs) are key factors in the tumor microenvironment, which have been implicated in cancer cell progression. It has also been reported that vesicles called exosomes produced by these CAFs play an important role in cancer progression. A research group investigated the effect of CAF-derived exosomes on the growth of malignant melanoma cells. They found that CAF-derived...

In North America's hottest, driest desert, climate change is causing the decline of plants once thought nearly immortal and replacing them with shorter shrubs that can take advantage of sporadic rainfall and warmer temperatures.

Weight loss was associated with decreased risk factors for cardiovascular disease and Type 2 diabetes for at least five years -- even if some weight was regained, according to a review of research on behavioral weight loss programs. People who lost weight through an intensive behavioral weight loss program had lower systolic blood pressure levels, total cholesterol-to-good cholesterol ratio and...

New study demonstrates that the most endangered turtles and crocodile species are those that have evolved unique life strategies. Many of the most threatened species carry out important ecosystem functions that other species depend on. Habitat loss was identified as the key overall threat to turtles and crocodiles, followed by climate change and global trade. Unique species faced additional...

In interventions designed to encourage more sustainable and climate-smart behavior, examples of what other people are doing and financial 'carrots' are more important than providing knowledge and facts. This has been shown in an international second-order meta-analysis of more than four hundred primary studies. However, all types of climate mitigation interventions have a relatively small effect...

An international research team develops a rubric for governments and policymaking bodies to evaluate preparedness for ocean acidification.

Scientists develop process to remove toxic heavy metals from coal fly ash, making for greener, stronger concrete.

Researchers have developed a practical way to produce green hydrogen using sustainable catalysts and say their work is a major step towards production simpler, more affordable and more scalable.

Shooting ions is very different from shooting a gun: By firing highly charged ions onto tiny gold structures, these structures can be modified in technologically interesting ways. Surprisingly, the key is not the force of impact, but the electric charge of the projectiles.

A fuel cell under the skin that converts blood sugar from the body into electrical energy sounds like science fiction. Yet it apparently works perfectly.

Even supposedly adaptable mammal species face increased risk of extinction.

Data from 124 societies shows that dogs' functions predict their treatment, with closer bonds forming in societies where dogs have multiple roles.
