Science Daily - 09/02/2024
In a win for chemistry, inventors have designed a closed-loop path for synthesizing an exceptionally tough carbon-fiber-reinforced polymer and later recovering all of its starting materials.

Researchers unveil method to detect 'forever chemicals' in under 3 minutes

Science Daily - 09/02/2024
PFAS have earned the name 'forever chemicals' with good reason -- the human-made compounds, which can take thousands of years to degrade and are found in everything from grease-resistant food packaging to water-repellent clothing, have made their way into nearly half the U.S. tap water supply.

Technique could improve the sensitivity of quantum sensing devices

Science Daily - 09/02/2024
A new technique can control a larger number of microscopic defects in a diamond. These defects can be used as qubits for quantum sensing applications, and being able to control a greater number of qubits would improve the sensitivity of such devices.

How one type of lung cancer can transform into another

Science Daily - 09/02/2024
Lung tumors called adenocarcinomas sometimes respond to initially effective treatments by transforming into a much more aggressive small cell lung cancer (SCLC) that spreads rapidly and has few options for treatment. Researchers have developed a mouse model that illuminates this problematic process, known as histological transformation. The findings advance the understanding of how mutated genes can trigger cancer evolution and suggest targets for more effective treatments.

This common medication could save half a million children's lives each year. So why is it underprescribed?

Science Daily - 09/02/2024
Health care providers in developing countries know that oral rehydration salts (ORS) are a lifesaving and inexpensive treatment for diarrheal disease, a leading cause of death for children worldwide -- yet few prescribe it. A new study suggests that closing the knowledge gap between what treatments health care providers think patients want and what treatments patients really want could help save half a million lives a year and reduce unnecessary use of antibiotics.

Foul fumes pose pollinator problems

Science Daily - 09/02/2024
Scientists have discovered that nighttime air pollution -- coming primarily form car exhaust and power plant emissions -- is responsible for a major drop in nighttime pollinator activity. Nitrate radicals (NO3) in the air degrade the scent chemicals released by a common wildflower, drastically reducing the scent-based cues that its chief pollinators rely on to locate the flower. The findings show how nighttime pollution creates a chain of chemical reactions that degrades scent cues, leaving flowers undetectable by smell. The researchers also determined that pollution likely has worldwide impacts on pollination.

Scientists debunk role of 'junk cells' in fight against malaria

Science Daily - 09/02/2024
Researchers have discovered a previously unknown ability of a group of immune system cells, known as Atypical B cells (ABCs), to fight infectious diseases such as malaria. The scientists say ABCs could also be key to developing new treatments for chronic autoimmune conditions such as lupus.

Physicists capture the first sounds of heat 'sloshing' in a superfluid

Science Daily - 09/02/2024
For the first time, physicists have captured direct images of 'second sound,' the movement of heat sloshing back and forth within a superfluid. The results will expand scientists' understanding of heat flow in superconductors and neutron stars.

How emotions affect word retrieval in people with aphasia

Science Daily - 09/02/2024
People with aphasia have more trouble coming up with words they want to use when they're prompted by images and words that carry negative emotional meaning, new research suggests.

Analysis of biological networks helps explain the complexity of multiple sclerosis

Science Daily - 09/02/2024
An international study has used a computational biology tool that, by analyzing a multitude of biological data from multiple sclerosis patients ranging from genetic information to the whole organism, reveals the relationship between elements of different biological scales and improves our knowledge and the diagnosis of the disease.

Researchers uncover genetic factors for severe Lassa fever

Science Daily - 09/02/2024
Researchers report the results of the first ever genome-wide association study (GWAS) of a biosafety level 4 (BSL-4) virus. The team found two key human genetic factors that could help explain why some people develop severe Lassa fever, and a set of LARGE1 variants linked to a reduced chance of getting Lassa fever. The work could lay the foundation for better treatments for Lassa fever and other similar diseases. The scientists are already working on a similar genetics study of Ebola susceptibility.

Nanofiber bandages fight infection, speed healing

Science Daily - 09/02/2024
Researchers have identified a new way to harness the antioxidant and antibacterial properties of a botanical compound to make nanofiber-coated cotton bandages that fight infection and help wounds heal more quickly.

Newly discovered genetic malfunction causes rare lung disease

Science Daily - 09/02/2024
The absence of a single immune cell receptor has been linked to both fewer defenses against mycobacterial infections, such as TB, and damaging buildup of sticky residue in the lungs.

Why politics bring out the worst in us

Science Daily - 09/02/2024
In a survey involving a total of 2,472 respondents, researchers asked participants about nonpolitical and political moral behavior and nonpolitical and political moral tolerance. They found people more willing to behave badly in political contexts -- and more willing to tolerate bad behavior among potliticians they support.

Low voice pitch increases standing among strangers

Science Daily - 09/02/2024
If you're looking for a long-term relationship or to boost your social status, lower your pitch, according to researchers studying the effects of voice pitch on social perceptions. They found that lower voice pitch makes women and men sound more attractive to potential long-term partners, and lower voice pitch in males makes the individual sound more formidable and prestigious among other men.

Ancient pollen trapped in Greenland ice uncovers changes in Canadian forests over 800 years

Science Daily - 09/02/2024
The Greenland ice sheet lies thousands of miles from North America yet holds clues to the distant continent's environmental history. Nearly two miles thick in places, the ice sheet grows as snow drifts from the sky and builds up over time. But snow isn't the only thing carried in by air currents that swirl around the atmosphere, with microscopic pollen grains and pieces of ash mixing with snowfall and preserving records of the past in the ice. A new study examined these pollen grains and identified how eastern Canada's forests grew, retreated, and changed through time.

New PET tracer detects inflammatory arthritis before symptoms appear

Science Daily - 09/02/2024
A novel PET imaging technique can noninvasively detect active inflammation in the body before clinical symptoms arise, according to new research. Using a PET tracer that binds to proteins present on activated immune cells, the technique produces images of ongoing inflammation throughout the body, such as rheumatoid arthritis. This makes it easier for physicians to correctly diagnose and treat patients.

Combining materials may support unique superconductivity for quantum computing

Science Daily - 09/02/2024
A new fusion of materials, each with special electrical properties, has all the components required for a unique type of superconductivity that could provide the basis for more robust quantum computing.
