The understanding of the clustering and movement of microswimmers has a range of applications from human health to tackling ecological problems.

Researchers have succeeded in understanding the biosynthetic mechanisms for the production of the natural product cyanobacterin, which is produced in small quantities by the cyanobacteria Scytonema hofmanni. In the process, they also discovered a new class of…

T cells, biology textbooks teach us, are the soldiers of the immune system, constantly on the ready to respond to a variety of threats, from viruses to tumors. However, without rest and maintenance T cells can die and leave their hosts more susceptible to…

We often think of biological arms races occurring between the immune system and pathogens, or predator and prey, but biologists have now discovered an example that plays out within a single genome. Their work in fruit flies may have implications for key…

Many types of animals, including humans, successfully coexist with retroviruses, and we know that ancient retrovirus viral elements can even be found within our genome. We also know that these endogenous retroviruses can be utilized for development and…

Due to global warming, temperatures in the Arctic are climbing rapidly. As a result, the treeline for Siberian larch forests is steadily advancing to the north, gradually supplanting the broad expanses of tundra which are home to a unique mix of flora and…

Artificial Intelligence (AI) can track the health of coral reefs by learning the 'song of the reef', new research shows.

An iconic coral species found in UK waters could expand its range due to climate change, new research shows.

For tens of thousands of years, Aboriginal Australians have created some of the world's most striking artworks. Today their work continues long lines of ancestral traditions, stories of the past and connections to current cultural landscapes, which is why…

New research has big implications for genomic medicine. Scientists have defined with atomic precision a new genome editing tool that is less than half the size of CRISPR-Cas9 -- currently the most reliable genome editing system. This new tool would allow…

Tie-dyeing is a fun activity that can spice up clothes with colorful patterns. Although kits are available in stores, nature provides dyes that can be extracted from items found in one's yard -- for example, acorns and rust. Researchers now present a 'green'…

Recently conducted tests used new algorithms to outperform state-of-the-art programming for autonomous underwater sonar imaging, significantly improving the speed and accuracy for identifying objects such as explosive mines, sunken ships, airplane black boxes,…

An entirely new class of super-reactive chemical compounds has been discovered under atmospheric conditions. Researchers have documented the formation of so-called trioxides -- an extremely oxidizing chemical compound that likely affects both human health and…

The raw material for evolution is much more abundant in wild animals than we previously believed, according to new research.

A synthesized antibiotic derived from computer models of bacterial gene products appears to neutralize even drug-resistant bacteria. The compound, named cilagicin, works well in mice and employs a novel mechanism to attack MRSA, C. diff, and several other…

Scientists have finally put to bed a long-standing question over the role of Earth's orbit in driving global ice age cycles.

A recently developed catalyst for breaking down plastics continues to advance plastic upcycling processes. In 2020, scientists developed the first processive inorganic catalyst to deconstruct polyolefin plastics into molecules that can be used to create more…

Plastic packaging waste is everywhere. Our plastic bottles, food wrappings, and grocery bags litter the landscape and pollute the global environment. A new study explores the global patterns of plastic packaging waste. The study finds three countries -- the…

The percentage of water in arc volcanoes, which form above subduction zones, may be far more than many previous studies have calculated. This increased amount of water has broad implications for understanding how Earth's lower crust forms, how magma erupts…

Researchers are using light in novel ways to better image biological samples.

Even the smallest marine invertebrates -- some barely larger than single-celled protists -- are home to distinct and diverse microbial communities, or microbiomes, according to biologists. The study underscores that a vast diversity of animals have…

Chondroitin sulfate proteoglycans (CSPGs), commonly obtained from salmon nasal cartilage, are a key ingredient of various health foods. As the popularity of health foods increases, scientists are searching for alternative sources of CSPGs. Now, researchers…

DNA molecules called plasmids -- some of which protect bacteria from antibiotics -- can spread rapidly through bacterial 'communities' that are treated with antibiotics, new research shows.

Chemists have processed waste plastic from end-of-life trucks into graphene for composite materials in new vehicles.

Children who were prescribed antibiotics inappropriately were more likely to develop complications such as diarrhea and skin rashes than children who were treated according to medical guidelines, according to a new study. This misuse of antibiotics resulted in…

Hypertension, or high blood pressure, is a major risk factor for heart disease and stroke, two of the leading causes of death in America. It's also one of the most common chronic conditions in the United States, with nearly half of U.S. adults considered…

USC researchers have found a correlation between tsunami severity and the width of the outer wedge -- the area between the continental shelf and deep trenches where large tsunamis emerge -- that helps explain how underwater seismic events generate large…

Wide-ranging use of smart technologies is raising global agricultural production but international researchers warn this digital-age phenomenon could reap a crop of another kind -- cybersecurity attacks. Complex IT and math modelling has highlighted the risks.

Researchers have demonstrated the benefits of a new non-radioactive, neutral negative staining reagent by imaging viruses at nanometer-scale. The salt-presenting reagent is a structurally stable and neutral molecule with a longer shelf life and less…

For the first time since its discovery 130 years ago one of the most mysterious fossil vertebrates has finally been classified, increasing our possible understanding of the first animals to crawl on Earth.
