A new method of scanning lungs is able to show in real time how air moves in and out of the lungs as people take a breath in patients with asthma, chronic obstructive pulmonary disease (COPD), and patients who have received a lung transplant. It enables experts to see the functioning of transplanted lungs and could enable medics to identify sooner any decline in lung function.
In a discovery that could redefine how we understand cellular resilience and adaptability, scientists have unlocked the secret interactions between a primordial inorganic polymer of phosphate known as polyphosphate (polyP), and two basic building blocks of life: DNA and the element magnesium. These components formed clusters of tiny liquid droplets -- also known as condensates -- with flexible and adaptable structures.
Many flies are plagued by parasitic wasps, which lay their eggs in fly larvae, turning them into surrogate wombs for wasp larvae. One common fly has successfully fought off its wasp predator by stealing a gene from bacteria that originated in bacteriophage. Biologists inserted that gene into other flies, making these flies resistance to wasps. This discovery shows that horizontal gene transfer may be more common in animals that people thought.
Climate change impacts not only life on land but also the largely unexplored deep-sea ecosystem, home to unique and largely unexplored fauna. Deep-sea animals, which have adapted to stable and extreme environments, are particularly vulnerable to changes in temperature and food availability. This raises a crucial question: What environmental factors are most important for deep-sea ecosystems, and how might they be disrupted?

A new gene editing tool that helps cellular machinery skip parts of genes responsible for diseases has been applied to reduce the formation of amyloid-beta plaque precursors in a mouse model of Alzheimer's disease, researchers report.
At the Berlin synchrotron radiation source BESSY II, the largest magnetic anisotropy of a single molecule ever measured experimentally has been determined. The larger this anisotropy is, the better a molecule is suited as a molecular nanomagnet. Such nanomagnets have a wide range of potential applications, for example, in energy-efficient data storage.
The standard medication levodopa does not always work against tremors in Parkinson's disease, especially in stressful situations. Propranolol, however, does work during stress, providing insight into the role of the stress system in tremors. MRI scans reveal that propranolol directly inhibits activity in the brain circuit that controls tremors. Doctors may consider this medication when levodopa is ineffective.
A year after becoming available, vaccines to protect against RSV in newborns and older adults are being more widely accepted by the American public, according to a new health survey.
A research team has developed a groundbreaking technology that can treat colon cancer by converting cancer cells into a state resembling normal colon cells without killing them, thus avoiding side effects.
In the first large-scale paired camera trap and autonomous recording survey for large African carnivores, researchers were able to identify individual leopards by their vocalizations with 93% accuracy.
Putting extra holiday cookies and leftovers in the freezer will not only extend their shelf life -- it could also put a dent in the U.S. household tendency to throw away edible food, a new study suggests.
Researchers have created a platform, called SIMPL2, that revolutionizes the study of protein-protein interactions by simplifying detection while improving measurement accuracy. While protein-protein interactions have previously been considered 'undruggable' using small molecules, the platform addresses this challenge by facilitating the measurement of these interactions -- improving our understanding of the types of molecules needed to control them.
Researchers have unveiled a critical mechanism that links cellular stress in the brain to the progression of Alzheimer's disease (AD). The study highlights microglia, the brain's primary immune cells, as central players in both the protective and harmful responses associated with the disease.
Hospitals that have adopted the Center for Medicare and Medicaid (CMS) 'hospital-at-home' program, which serves as an alternative to admission to brick-and-mortar facilities, are concentrated in large, urban, not-for-profit, and academic hospitals, highlighting need for targeted incentives to expand program to smaller, rural, and non-teaching hospitals.
Bright, twisted light can be produced with technology similar to an Edison light bulb, researchers have shown. The finding adds nuance to fundamental physics while offering a new avenue for robotic vision systems and other applications for light that traces out a helix in space.
