Oil droplets can be made to act like predators, chasing down other droplets that flee like prey. The behavior, which is controlled by chemical signaling produced by the droplets, mimics behavior seen among living organis...

Scientists have identified an old piece of the Pacific Ocean - the ancient remains of its long-ago seabed - extending hundreds of miles underneath China, as it is pulled downward into Earth's mantle transition zone.

Autoclaves, which are used to sterilize medical tools, require a steady supply of hot, pressurized steam. Researchers have come up with a way to generate that steam passively, using just the power of sunlight, to help ma...

Researchers have discovered that a protein thought to only be involved in the development of neurons in the brain also plays a major role in the development and growth of pancreatic cancer. Their findings demonstrate for...

The femur of Sahelanthropus tchadensis, generally regarded as the oldest known hominin, has finally been scientifically examined. The results suggest it walked on four legs, so may not actually be a close human relative ...

A recent research study conducted by City, University of London's Professor Christoph Bruecker and his team has revealed how micro-structured finlets on owl feathers enable silent flight and may show the way forward in r...

Older women who live in locations with higher levels of air pollution may have more brain shrinkage, the kind seen in Alzheimer's disease, than women who live in locations with lower levels, according to a new study.

In a study on human ovarian cancer cells in mice, researchers discovered a transient, cooperative interaction between cell subpopulations that allows otherwise nonmetastatic tumor cells to become aggressive and spread.

Researchers have demonstrated that the CRISPR/Cas9 system is very effective in treating metastatic cancers, a significant step on the way to finding a cure for cancer. The researchers developed a novel lipid nanoparticle...

Aging is a process that affects not only living beings. Many materials, like plastics and glasses, also age--i.e. they change slowly over time as their particles try to pack better--and there are already computer models ...

Stress and depression may increase the risk of dementia and cognitive decline in older members of the LGBTQ community, a new study reports.

An easy way to make millirobots by coating objects with a glue-like magnetic spray has been developed. Driven by the magnetic field, the coated objects can crawl, walk, or roll on different surfaces. As the magnetic coat...

Scientists have discovered how a common virus in the human gut infects and takes over bacterial cells - a finding that could be used to control the composition of the gut microbiome, which is important for human health. ...

Researchers have identified a molecule that protects mice from brain infections caused by Venezuelan equine encephalitis virus (VEEV), a mosquito-borne virus notorious for causing fast-spreading, deadly outbreaks in Mexi...

Researchers find a key mutation causing abnormal transport of BACE1, the enzyme responsible for processing the Alzheimer's disease-linked amyloid protein. Identification of this mutation, which is more common among Afric...

Last year, researchers identified the early origins of neural crest cells -- embryonic cells in vertebrates that travel throughout the body and generate many cell types -- in chick embryos. Now the researchers have used ...

Infections with two pathogens pose a serious threat in the clinics. Researchers have developed a technique that provides new insights into this process and can be used as an early warning system.

Researchers have discovered how the MSL complex responsible for dosage compensation can distinguish the X chromosome from autosomes in flies. A lab used a unique research approach to determine the minimal molecular compo...

Current chemotherapy regimens slow cancer progression and save lives, but these powerful drugs affect both healthy and cancerous cells. Now, researchers have designed DNA-based nanogels that only break down and release t...

A study found a significant increase in the number of online search queries for 'insomnia' between April and May 2020, when governments across the U.S. and around the world implemented stay-at-home orders in response to ...

Researchers want to make it easier to catch diseases earlier in the process, improving patient outlooks and taking some of the load off the medical system.

Two recently published studies include important findings related to SARS-CoV-2 transmission and the COVID-19 pandemic: Domestic cats can be asymptomatic carriers of SARS-CoV-2, but pigs are unlikely to be significant ca...
