New research found that driving skills measured at the time of licensure on a virtual driving assessment (VDA), which exposes drivers to common serious crash scenarios, helps predict crash risk in newly licensed young drivers. This study brings the research community one step closer to identifying which skill deficits put young new drivers at higher risk for crashes. With this cutting-edge information, more personalized interventions can be developed to improve... Read more ›

A study describes the productive forces of the Chalcolithic communities of the southern half of the Iberian Peninsula as being very diverse, both in the type of tasks performed and in intensity, with a high degree of cooperation and no apparent signs of dependence between the different types of settlements or of political centralization. The work, based on the analysis of macrolithic tool data and the additional support of bioarchaeological... Read more ›

The heat shock response of cells is a classic model of biological adaptation, part of the fundamental processes of life -- conserved in creatures from single-celled yeast to humans -- that allow our cells to adjust to changing conditions in their environment. For years, scientists have focused on how different genes respond to heat stress to understand this survival technique. Now, thanks to the innovative use of advanced imaging techniques,...

Despite steps toward decreasing deforestation, uncontrolled wildfires are threatening environmental gains in Brazilian Amazonia, one of the world's most critical carbon sinks and a region of high biological and cultural diversity.  Read more ›

A multiyear analysis tested whether management zone maps based on soil conditions, topography or other landscape features can reliably predict which parts of a cornfield will respond best to higher rates of seeding or nitrogen application. The study found that -- contrary to common assumptions -- crop-plot responses to the same inputs vary significantly from year to year. The most unpredictable factor -- the weather -- seemed to have the... Read more ›

Researchers have developed a visualization tool that combines high-speed cameras and fluorescent injection to distinguish tumor tissue from normal tissue across cancer types. The team evaluated the new imaging technology, known as fluorescence lifetime (FLT) imaging, using specimens from more than 60 patients that underwent surgery of various cancers. The team reported that the technique was over 97 percent accurate across tumor types, with the potential to improve the accuracy... Read more ›

One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops. Read more ›

A new study of sleep in women shows that delaying bedtime by just 90 minutes each night damages cells that line the blood vessels, supporting the hypothesis that poor sleep is linked to heart health. Read more ›

Reducing overall calorie intake may rejuvenate your muscles and activate biological pathways important for good health, according to researchers. Decreasing calories without depriving the body of essential vitamins and minerals, known as calorie restriction, has long been known to delay the progression of age-related diseases in animal models. This new study suggests the same biological mechanisms may also apply to humans. Read more ›

Researchers conducted a statewide survey of all patients on breathing machines in hospitals and long-term care facilities and found that a significant percentage of them harbored two pathogens known to be life-threatening in those with compromised immune systems. One pathogen, Acinetobacter baumannii, was identified in nearly 31 percent of all patients on ventilators to assist with their breathing; Candida auris was identified in nearly 7 percent of patients on ventilators,...

Phytoplankton, tiny photosynthetic organisms in the ocean, play a crucial role in the global carbon cycle and influence Earth's climate. A new study reveals how variations in the physiology of phytoplankton, particularly regarding nutrient uptake, can impact the chemical composition of the ocean and even the atmosphere. This suggests that changes in marine phytoplankton physiology can affect global climate. Read more ›

A novel therapeutic approach that combines human epidermal growth receptor factor 2 (HER2)-targeted therapies with the cholesterol-lowering drug lovastatin can reduce the number of cancer treatments required to prevent tumor growth. Monitored by immuno-PET scans, this combination therapy has the potential to personalize treatment for cancer patients and spare them from harmful side effects. Read more ›

Scientists recently presented a report on the status of global water resources. According to this report, large parts of the world experienced drier conditions in 2022 than those recorded on average for the equivalent periods over the last 30 years. Read more ›

Newly published research on indoor air quality shows wildfire smoke may linger in homes long after the initial blaze has been put out or winds have shifted. The findings show that wildfire smoke can attach to home surfaces like carpet, drapes or counters -- extending the exposure for those inside and potentially causing health problems even after an initial cleaning activity by air purifiers.

Fecal microbe transplants from healthy donors can treat patients with recurrent Clostridium difficile infections. However, after tens of thousands transplants, little was known about which donor strains provide long-term engraftment, and which engraft early after the transplant. Most failures of fecal microbe transplantation occur in the first four weeks. Researchers have now found 19 Bacteroides vulgatus genes that were unique to three strains that show early engraftment in patients after...

Relief could be on the way for people with painful hand osteoarthritis after a new study found an affordable existing drug can help. Until now there has been no effective treatment. The paper investigated methotrexate, a low-cost, effective treatment for inflammatory joint conditions such as rheumatoid arthritis and psoriatic arthritis. It has been widely used in Australia and globally since the early 1980s.  Read more ›
