A CU Boulder astrophysicist is searching the light coming from a distant, and extremely powerful celestial object, for what may be the most elusive substance in the universe: dark matter.
Stopping the cannibalistic behavior of a well-studied enzyme could be the key to new drugs to fight age-related diseases, according to a new study published online in Nature Cell Biology. For the first time, researchers in the Perelman School of Medicine at the University of Pennsylvania show how the self-eating cellular process known as autophagy is causing the SIRT1 enzyme, long known to play a...
Complex brain circuits in rodents can organise themselves with genetics playing only a secondary role, according to a new computer modelling study published today in eLife.
New research led by Flinders University has found a link between beta-blockers and survival outcomes in some breast cancer patients. Beta-blockers, commonly used to manage cardiovascular disease, were negatively associated with survival outcomes in patients with HER2 (Human Epidermal Growth Factor Receptor 2) positive advanced breast cancer, according to a new paper in the Frontiers In Oncology.
Amie Ashcraft has studied the availability and accessibility of emergency contraception in West Virginia pharmacies. She and her research team found that chain pharmacies--like CVS and Walmart--were more likely than independent ones to keep emergency contraception in stock.
Serious traumatic injuries are a health event that can begin a trajectory toward chronic health and social challenges. Research on patient outcomes following traumatic injuries establishes the pervasive nature of injuries' long-term consequences in physical, psychological, social and economic well-being, which may persist months and even years after an injury hospitalization. In light of this...
A new study in mBio provides the first evidence that the seasonal colds you've had in the past could protect you from COVID-19. The study, authored by infectious disease experts at the University of Rochester Medical Center, also suggests that immunity to COVID-19 is likely to last a long time - maybe even a lifetime.
Everyone's heard of THC and CBD. But many other active compounds in cannabis interact to influence its effects. A new study confirms that those compounds are seldom tested for, and strain name is not indicative of potency or chemical makeup. Machine learning techniques could help fill the knowledge gap.
Life-threatening cardiac arrhythmias can be linked to the functional and structural consequences of gene mutations.
Individual-level changes in alcohol use and the consequences associated with alcohol use by US adults from before to during the COVID-19 pandemic are examined in this study.
China's success in improving air quality by cutting polluting emissions may have a negative knock-on effect on climate change overall, a new study has found.
A repeated testing protocol for COVID-19 among patients with cancer was examined in this quality improvement study.
We know that DNA molecules express heredity through genetic information. However, in the past few years, scientists have discovered that DNA can conduct electrical currents. This makes it an interesting candidate for roles that nature did not intend for this molecule, such as smaller, faster and cheaper electric circuits in electronic devices, and to detect the early stages of diseases like...
Catalase, a naturally occurring enzyme, holds potential as a low-cost therapeutic drug to treat COVID-19 symptoms and suppress the replication of coronavirus inside the body.
Scientists have built a computer 'brain circuit', or artificial neural network, that mirrors human decision-making processes and sheds light on how circuits might be altered in psychiatric diseases.
New study addresses a mystery first raised in March: Why do some people with COVID-19 develop severe inflammation? The research shows how the molecular structure and sequence of the SARS-CoV-2 spike protein could be behind life-threatening inflammatory conditions MIS-C and cytokine storm.
With implications for the transmission of diseases like COVID-19, researchers have found that ordinary conversation creates a conical 'jet-like' airflow that quickly carries a spray of tiny droplets from a speaker's mouth across meters of an interior space.
Tobacco companies use covert marketing tactics and exploit loopholes in Australian tobacco control laws to promote their products despite current tobacco advertising bans, finds new research from University of Sydney and Cancer Council NSW.
Sitagliptin, a drug to lower blood sugar in type 2 diabetes, also improves survival in diabetic patients hospitalized with COVID-19, suggests a multicenter observational study in Italy. Patients given sitagliptin in addition to insulin had a mortality rate of 18 percent as compared with 37 percent in matched patients receiving only insulin. Led by Paolo Fiorina, MD, PhD, of Boston Children's...
A newly identified genetic factor allows adult skin to repair itself like the skin of a newborn. The discovery has implications for wound treatment and preventing some of the aging process in skin. Researchers identified a factor in the skin of baby mice controlling hair follicle formation. When it was activated in adult mice, their skin was able to heal wounds without scarring. The reformed skin...
Researchers at Cima and the Clinica Universidad de Navarra (Spain) have led an international study identifying the cardiac cells responsible for repairing the damage to this organ after infarction. These "restorative" cells are a subpopulation of cardiac fibroblasts that play a fundamental role in the creation of the collagen scar needed to avoid the rupture of the ventricular wall. The research...
Researchers from TU Delft have now developed a new model that describes driving behaviour on the basis of one underlying 'human' principle: managing the risk below a threshold level. This model can accurately predict human behaviour during a wide range of driving tasks. In time, the model could be used in intelligent cars, to make them feel less 'robotic'. The research will be published in Nature...
A team of researchers led by biomedical scientist Declan McCole at the University of California, Riverside, has found that the drug tofacitinib, also called Xeljanz and approved by the FDA to treat rheumatoid arthritis and ulcerative colitis, can repair permeability defects in the intestine. "Our work could help improve identification of patients who will be better responders to this drug," says...
A new software tool developed at Cincinnati Children's can employ early MRI scan data to predict which preterm infants are most at risk of brain developmental disorders.
If you have been surrounded by the sight and smell of pine trees, you may have taken a closer look at the needles and then wondered how their properties are influenced by rainfall. In Physics of Fluids, researchers are currently probing how well pine needles allay the impact of rain beneath the tree. They explored the impact of raindrops onto fixed, noncircular fibers of the longleaf pine by using...
