Scientists demonstrate a novel approach for creating high-performance ultrafast lasers on nanophotonic chips. The new advance will enable pocket-sized devices that can perform detailed GPS-free precision navigation, medical imaging, food safety inspect…

Researchers have developed deep-learning algorithms that let users pick which sounds filter through their headphones in real time. Either through voice commands or a smartphone app, headphone wearers can select which sounds they want to include from 20…

An international group of scientists has called for the United Nations Treaty on Plastic Pollution to focus more on measures to reduce the production and consumption of plastics and the prevention of future plastic waste, rather than on the unselective…

A bioengineer has developed synthetic enzymes that can control the behavior of the signaling protein Vg1, which plays a key role in the development of muscle, bone and blood in vertebrate embryos. The team of researchers is using a new approach, called…

Researchers have developed a new method to image polymerization catalysis reactions one monomer at a time. 

Research and treatment of psychiatric disorders are stymied by a lack of biomarkers — objective biological or physiological markers that can help diagnose, track, predict, and treat diseases. In a new study, researchers use a very large dataset to ide…

Scientists took thousands of measurements of firefighters in training to learn more about how the body responds to vigorous exercise.

From Wi-Fi-connected home security systems to smart toilets, the so-called Internet of Things brings personalization and convenience to devices that help run homes. But with that comes tangled electrical cords or batteries that need to be replaced. Now…

Researchers have developed a new way of counting microorganisms that works as much as 36 times faster than conventional methods, cuts plastic use more than 15-fold and substantially decreases the cost and carbon footprint of biomedical research. The te…

Scientists used their expertise in quantum biology, artificial intelligence and bioengineering to improve how CRISPR Cas9 genome editing tools work on organisms like microbes that can be modified to produce renewable fuels and chemicals.

New experimental evidence suggests that substances known as narrow-spectrum Wnt signaling inhibitors — which could have fewer side effects than other related substances — are capable of suppressing the growth of breast cancer tumors in mice.

Rather than a slow, gradual process as Darwin envisioned, biologists can now see how evolutionary changes unfold on much more accelerated timescales. Using an accelerated arms race between bacteria and viruses, researchers are documenting rapid evoluti…

UCLA researchers have described a previously unknown step in the complex process by which dietary cholesterol is processed in the intestines before being released into the bloodstream — potentially revealing a new pathway to target in cholesterol trea…

Desert birds lay larger eggs when they have more helpers to feed their chicks, new research shows.

The boom in phones, laptops and other personal devices over the last few decades has been made possible by the lithium-ion (Li-ion) battery, but as climate change demands more powerful batteries for electric vehicles and grid-scale renewable storage, l…

Scientists have observed, for the first time in the visible range, a glow on the night side of the planet Mars. These new observations provide a better understanding of the dynamics of the upper atmosphere of the Red Planet and its variations throughou…

A drug currently in clinical trials as a cancer therapy can also stimulate pancreatic beta cells to secrete insulin, revealing a previously unknown mechanism for insulin regulation in type 2 diabetes, according to a new study. The preclinical discovery…

Engineers developed a technique to quickly identify a range of potential failures in a system before they are deployed in the real world.
