This discovery offers hope for developing drugs to protect against the virus's lethal complication of pneumonia.
Researchers at TUM discovered that brain cells, specifically astrocytes, regulate sugar intake and adjust metabolism in response to hormones like insulin and leptin. This paradigm shift could lead to new treatments for diabetes and obesity by targeting multiple cell types involved in metabolic processes.
Researchers found that watching food commercials increased children's emphasis on taste over healthiness, leading to faster and more impulsive food decisions. The study also showed that the ventromedial prefrontal cortex was significantly more active after watching food commercials.
Researchers construct a biophysical model to study global crosstalk in gene regulation, finding that it exists due to molecular recognition limits. The 'crosstalk floor' implies that there is a fundamental limit to this phenomenon, even with optimal adjustments to transcription factor concentrations.
A study suggests that humans' disproportionately large brain size resulted from sizing each other up in large social groups. The research proposes that helping others who are at least as successful as themselves favored by evolution. This idea has implications for engineering intelligent machines to decide cooperation and generosity.
Researchers have created low-cost and sensitive assays to analyze Fragile X-related disorders, enabling preclinical and clinical research on this genetic mutation. The new tests can detect even small changes in DNA methylation and may be suitable for initial patient screening.
The VesiVax system uses virus-like particles to induce strong immune responses against various diseases. Dr. Qizhi Cathy Yao is developing better adjuvants for pancreatic cancer and Chagas disease using the system.
A survey of 77 atmospheric scientists found no evidence to support the 'chemtrails' conspiracy theory, which claims a secret government program is releasing toxic chemicals into the air. The researchers cited methods for collecting samples as a possible cause of faulty results.
A study by Carnegie Institution for Science and University of California Irvine surveyed top atmospheric scientists, finding that 76 out of 77 rejected the existence of a secret spraying program. Experts attribute alleged 'chemtrails' to airplane contrail formation and poor data sampling.
A new study found that Finland's national tobacco policies are responsible for a significant decrease in the incidence of subarachnoid haemorrhage, the most fatal form of stroke. The prevalence of SAH declined by 45% among women and 38% among men under 50 over a 15-year period.
Research from University of Manchester found that aerobic exercise training can significantly improve patients' brain functioning and reduce cognitive deficits associated with schizophrenia. The study showed that exercise programs combined with medication led to better outcomes in areas such as social understanding, attention spans, an...
Researchers at EPFL have developed a new method for synthesizing aryl-containing amines, a crucial class of compounds in pharmaceuticals. The new method uses nitroarenes as a starting material and eliminates the need for expensive intermediate steps, reducing costs and increasing efficiency.
The Fermi mission has excluded a small range of axion-like particles that could have comprised about 4 percent of dark matter, while also providing the strongest constraints to date for certain masses. Additionally, researchers found no statistically significant signal from dark matter annihilation in the Small Magellanic Cloud.
Researchers found that 64% of treatment-resistant depression patients had a deficiency in neurotransmitter metabolism, which improved symptoms with underlying deficiency treatment. The study suggests a new avenue for patients who have failed conventional treatments.
The PPPL will optimize lithium delivery systems for long-pulse plasmas on the Experimental Advanced Superconducting Tokamak (EAST) in China. The goal is to protect plasma-facing components and prevent impurities from halting fusion reactions.
Researchers from NIST discovered a 'sweet spot' for mass-producing polymer solar cells, exceeding 9.5% power conversion efficiency, without sacrificing performance. The findings suggest that high-volume production methods can yield efficient photovoltaic devices with greater structural variability.
Researchers studied magnesium chloride's high-pressure structural behavior and found it remained stable beyond 40 GPa, contradicting established structural systematics. The findings could improve confidence in predicting products and performance of detonated chemical formulations.
Scientists have established the first public collection of bacteria from the intestine of mice, providing comprehensive information on the mouse gut microbiota. The collection includes 76 cultured bacterial species, including 15 previously unknown taxa, and sheds light on the interactions between gut bacteria and their host.
Changes in intestinal flora caused by antibacterial drugs can reduce enzyme activity in the liver and kidneys, affecting drug metabolism and transport. This study suggests that altered intestinal flora may lead to reduced drug efficacy and increased side effects.
A nationwide study found that Black and Hispanic children and youth are less likely to receive mental health care than their white counterparts, despite similar rates of mental health problems. The study also revealed significant racial and ethnic disparities in substance abuse treatment and outpatient mental health services.
Researchers at Brookhaven National Laboratory have created a new imaging technique that allows scientists to probe the internal makeup of a battery during charging and discharging using different x-ray energies while rotating the battery cell. The technique produces a three-dimensional chemical map, enabling scientists to track chemica...
A recent University of Kansas study found that environmental regulations can increase firms' profits when implemented in the right balance. When wastewater discharge limits were stringent and inspections were frequent, profits declined as expected, but under conditions where one was stronger than the other, profits improved. This sugge...
The Global Precipitation Measurement mission gathered extensive rainfall data on Louisiana storms, finding intense rainfall rates of over 3.9 inches per hour and storm tops reaching 9.9 miles high.
Researchers at Cornell University have discovered a method to produce vortex ring-derived particles, which can be used for cell delivery and cell-free protein production. This technique, developed by Duo An and his team, has the potential to greatly improve treatments for Type 1 diabetes patients.
The study found a small number of species associated with periodontitis, but not gingivitis, including Prevotella, Treponema, and Selemonas. This research may lead to an inexpensive and rapid point-of-care test based on distinguishing the two conditions' microbiomes.
A team of marine biologists from the University of Copenhagen has used carbon-14 dating to estimate the lifespan of Greenland sharks, finding that they live for at least 272 years. This method was previously only used in archaeological contexts, but is now being applied to fish biology due to the species' extraordinary longevity.
Researchers analyzed responses from over 600 URM undergraduates to identify sources of research self-efficacy and confidence in their abilities.
