Synthetic microparticles more intricate than some of the most complicated ones found in nature have now been produced. Researchers also investigated how that intricacy arises and devised a way to measure it.

While researchers have suggested that individuals who base their self-worth on their financial success often feel lonely in everyday life, a new study has taken initial steps to better understand why this link exists.
A new neuroimaging study points to an answer of what may have driven the evolutionary development of creativity.
Canada lynx are losing ground in Washington state, even as federal officials are taking steps to remove the species' threatened status under the Endangered Species Act. A massive monitoring study has found the big cat on only about 20% of its potential habitat in the state.
Engineers have created a laser treatment method that could potentially turn any metal surface into a rapid bacteria killer -- just by giving the metal's surface a different texture.
A new article calls attention to the risk posed by overreliance on COVID-19 testing to make clinical and public health decisions. The sensitivity of reverse transcriptase-polymerase chain reaction (RT-PCR) testing and overall test performance characteristics have not been reported clearly or consistently in medical literature, the article says.
Much remains unknown about COVID-19, but many studies already have indicated that people with cardiovascular disease are at greater risk of COVID-19. There also have been reports of ST-segment elevation (STE), a signal of obstructive coronary artery disease, in patients with COVID-19 who after invasive coronary angiography show no sign of the disease.
Researchers have pinpointed a genetic variation responsible for driving the development of inflammatory bowel disease (IBD). The genetic pathway associated with this variation is involved in other immune disorders, suggesting the mechanism they identified could serve as an important therapeutic target.
Not quite planets and not quite stars, brown dwarfs are cosmic in-betweeners. Learning about their atmospheres could help us understand giant planets around other stars.
A multidisciplinary team of researchers at the University of Illinois at Urbana-Champaign has developed tiny sensors that measure oxygen transport in bovine lung tissue. The study -- which establishes a new framework for observing the elusive connection between lung membranes, oxygen flow and related disease -- is published in the journal Nature Communications.
Using existing data from controlled experiments and computer simulations, researchers have found that host contact rates and habitat structure affect transmission rates of Bsal among eastern newts, a common salamander species found throughout eastern North America.
New research suggests that large-scale environmental factors influence the size of one of the ocean's most abundant forage species. Recently, scientists found that anthropogenic influences affected menhaden in the Atlantic more than in the Gulf, where environmental factors were the more dominant predictors of growth.
There is plenty of scientific evidence that the health of a mother can impact the health of her child. Now a new study flips that relationship around: Researchers have discovered the health of the fertilized embryo determines the functional health of the mother, which has implications for healthy aging, stress resilience and suppression of protein damage. Essentially, a bad egg does good by...
A group of trees that grow fast, live long lives and reproduce slowly account for the bulk of the biomass -- and carbon storage -- in some tropical rainforests, a team of scientists says. The finding that these trees, called long-lived pioneers, play a much larger role in carbon storage than previously thought may have implications in efforts to preserve forests as a strategy to fight climate...
Every moment of the day we are surrounded by smells. Odors can bring back memories, or quickly warn us that food has gone bad. But how does our brain identify so many different odors? And how easily can we untangle the ingredients of a mixture of odors? Scientists have taken an important step toward answering these questions, and the secret lies inside the nose.
Liquid metals and alloys have exceptional properties that make them suitable for electrical energy storage and generation applications.
Four fossilized monkey teeth discovered deep in the Peruvian Amazon provide new evidence that more than one group of ancient primates journeyed across the Atlantic Ocean from Africa. The teeth are from a newly discovered species belonging to an extinct family of African primates known as parapithecids. Fossils discovered at the same site in Peru had earlier offered the first proof that South...
Researchers have discovered six new coronaviruses in bats in Myanmar -- the first time these viruses have been detected anywhere in the world. Future studies will evaluate the potential for transmission across species to better understand the risks to human health.
What does it actually look like deep inside our ears? This has been very difficult to study as the inner ear is protected by the hardest bone in the body. But with the help of synchrotron X-rays, it is now possible to depict details inside the ear three-dimensionally. Researchers have now used the method to map the blood vessels of the inner ear.
The antimicrobial properties of silver have been known for centuries. Now scientists are seeking to better understand how the noble metal kills bacteria to help combat antiobiotic-resistant 'superbugs.'
Some types of gut bacteria are better than others at stimulating certain immune cells, specifically CD8+ T cells. And while these CD8+ T cells normally help protect the body against cancer, overstimulating them may promote inflammation and exhaust the T cells -- which can actually increase susceptibility to cancer, according to new mouse model.
A novel 'learning while doing' clinical trial approach called REMAP helps doctors find the optimal trade-off between quickly adopting new therapies during a pandemic, such as the anti-malarial drug hydroxychloroquine, and waiting until they are tested in longer clinical trials. The trial learns from similar trials enrolling around the world and uses artificial intelligence to quickly arrive at...
New research indicates mantis shrimp use path integration to find their way back to their burrows after leaving to seek food or mates. That means they can track their distance and direction from their starting point. A series of creative experiments revealed that to do that, they rely on a hierarchy of cues from the sun, polarized light patterns, and their internal senses.
Oxidation of the sulfur atom in methionine is an important biomolecular reaction that can have a wide range of biological consequences depending on the context and the protein involved. Chemists have reported a new method for separation of methionine sulfoxide diastereomers that opens up new opportunities for studying their roles in biological processes.
Researchers created technology that uses optical imaging to better help surgeons map out tumors in the body and help them understand how certain diseases affect activity in the brain.
