Materials that can slow the cooling of highly energetic hot carriers could capture extra energy from the Sun.
Researchers at the Biozentrum of the University have demonstrated how bacteria coordinate cell division with the replication of their genetic material. In an interdisciplinary study they explain why the current concept of the bacterial cell cycle has to be rewritten. The results were published in eLife.
One of the wonders of cell biology is its symmetry. Mammalian cells have one nucleus and one cell membrane, and most humans have 23 pairs of chromosomes.
As the world warms, a new study is helping scientists understand how coniferous forests may respond to drought. The research addresses a classic question in the field: When conditions are dry for long periods of time, do trees survive by growing new roots to tap water sources, or by relying on established roots that already go deep?
Research on fossilized fish details the evolution of fins as they began to transition into limbs fit for walking on land.
For decades, therapy to strengthen pelvic muscles has been the standard treatment for men dealing with urinary incontinence after prostate surgery. But a new study suggests that may not be the best approach.
Grizzly bears spend many months in hibernation, but their muscles do not suffer from the lack of movement. In the journal 'Scientific Reports', a team led by MDC researcher Michael Gotthardt reports on how they manage to do this. The grizzly bears' strategy could help prevent muscle atrophy in humans as well.
Life as we know it requires phosphorus, and lots of it. But phosphorus is scarce. A University of Washington study, published Dec. 30 in the Proceedings of the National Academy of Sciences, reports that certain types of carbonate-rich lakes, which could have formed on early Earth, have the right chemistry to keep phosphorous levels high and available to organisms.
Until recently, Stemphylium leaf blight has been considered a minor foliar disease as it has not done much damage in New York since the early 1990s. However, onion growers in New York have recently seen an increase in the dieback of their crops, and scientists at Cornell University were surprised to discover that SLB was the cause.
MIV-711, a novel selective cathepsin K inhibitor, was not more effective than placebo for reducing pain related to knee osteoarthritis. However, MIV-711 significantly reduced bone and cartilage progression. Findings from a randomized, placebo-controlled study are published in Annals of Internal Medicine.
A growing number of Chinese scientists working in the United States and other parts of the world are returning to their homeland, enhancing China's research productivity.In a new study, researchers found that more than 16,000 researchers have returned to China from other countries since that nation has opened up to international engagement. More than 4,500 left the United States for China in 2017...
Tropical Cyclone Calvinia formed on Dec. 29 and by the next day, its clouds from a band of thunderstorms on its western side had blanketed the island of Mauritius in the Southern Indian Ocean.
NASA's Terra satellite passed over the Southern Pacific Ocean on Dec. 30, 2019 and found that Tropical Storm Sarai continued to move further away from Fiji and toward Tonga.
The North Atlantic Current transports warm water from the Gulf of Mexico towards Europe, providing much of north-western Europe with a relatively mild climate. However, scientists suspect that meltwater from Greenland and excessive rainfall could interfere with this ocean current. Simulations by scientists from the University of Groningen and Utrecht University showed that there is a 15 percent...
The simultaneous use of antibodies based on two differing mechanisms of action leads to a more effective destruction of tumors. This has been demonstrated by a study in animal models by medical oncologists and scientists at the University of Basel that has been published in the scientific journal PNAS. Patients who do not respond to current immunotherapy options could benefit most from this new...
Pregnant women exposed to persistent organic pollutants, or POPs, had slightly smaller fetuses than women who haven't been exposed to these chemicals, according to an analysis of ultrasound scans by researchers at the National Institutes of Health and other institutions.
A telephone survey conducted by researchers at UC San Francisco found that fewer than half of California pharmacies provided disposal instructions meeting US Food and Drug Administration guidelines, and just 10% followed the FDA's preferred recommendation to take back unused medications from their customers.
Scientists from Skoltech and Heriot-Watt University proposed extracting methane by injecting flue gas into permafrost hydrate reservoirs. Since the flue gas contains carbon dioxide, the new technology will also contributes to reduction of this greenhouse gas in the Arctic atmosphere. The results of their study were published in the journal Scientific reports.
Scientists at the Samara Polytech are developing a new area of mathematical modeling of locally nonequilibrium transfer processes and methods for their study.
A study in Botswana by Columbia University Mailman School of Public Health scientists finds that spikes in cases of life-threatening diarrhea in young children are associated with La Niña climate conditions. The findings published in the journal Nature Communications could provide the basis for an early-warning system that would allow public health officials to prepare for periods of increased...
Scientists have discovered that people who regularly sleep for more than 11 hours or less than 4 hours are 2-3 times more likely to have the incurable disease, pulmonary fibrosis, compared to those that sleep for 7 hours in a day. They attribute this association to the body clock.
Metal-organic frameworks (MOFs) are porous crystalline materials assembled from organic ligands and metal nodes. Construction of hierarchically porous MOFs is vital to achieve the augmentation of pore size to mesopores or macropores, which can enhance the diffusion kinetics of guests and improve the capacity. Recently, researchers from Texas A&M University summarized the latest advances in MOFs...
Research led by St. Michael's Hospital of Unity Health Toronto and published in The American Journal of Clinical Nutrition analyzed 28 studies from seven countries that explored the relationship between children drinking cow's milk and the risk of being overweight or obese.
The growing Tibetan Plateau since the Cenozoic has shifted the life's history by changing the regional geography and global climate; however, little is known about the details of the process. Based on fossils discovered from the plateau, a recent paper reviewed the role of the rising Tibetan Plateau played in shaping the modern biodiversity. Three evolutionary patterns have been recognized: Local...
The American coot is a somewhat drab water bird with gray and black feathers and a white beak, common in wetlands throughout North America. Coot chicks, however, sport outrageously bright orange and red feathers, skin, and beaks. A new study explains how the bright coloring of coot chicks fits in with the reproductive strategy of their less colorful parents.
