Physicists and chemists from Max Planck Institute and Heidelberg University develop method to directly image molecular structure of chiral molecules, revealing their absolute configuration and handedness. This breakthrough enables investigation of individual chiral molecules in the gaseous state.
Biologists at Ruhr-University Bochum have developed a DNA barcode for Podocarpaceae, the second-largest conifer family, to facilitate species identification. The project helps protect endangered populations by assigning unknown individuals to their respective species, promoting conservation efforts.
A legless, leaping fish that lives on land avoids predators by using camouflage to match its rocky environment, reducing attacks from birds, lizards, and crabs. The researchers found that the fish's unique colouration helped it survive in its new habitat, suggesting an evolutionary advantage.
Researchers have identified Sca1 stem cells as the key players in the regeneration of heart muscle cells in mammals. These stem cells increase their activity in response to heart damage, leading to the formation of new heart muscle cells.
The project utilizes GPS-equipped cars with varying wiper systems to measure rainfall intensity, offering a promising alternative to traditional rain gauges. By analyzing sensor readings, researchers can create a more extensive network of measurement points, leading to improved flood prediction and prevention.
Researchers have developed a new sea coral-based material that considerably improves the outcome of bone grafts in 16 patients. The material, called coralline hydroxyapatite/calcium carbonate (CHACC), has been shown to biodegrade after two years and promote natural bone healing.
Researchers at UC San Diego used quantitative models and microfluidic devices to study bacterial growth and evolution of drug resistance. They found that the expression of resistance genes depends on the bacterial colony's growth status and the effectiveness of the resistance mechanism. The interaction between drug and resistance is co...
Neuroscientists found that brain cells encode spatial information and form 'geotags' for memories, activated before recall. Spatial memory systems are linked to episodic memories, allowing researchers to predict recalled items with accuracy.
Researchers at Washington University in St. Louis have developed a new technique to isolate and examine a photosynthetic megacomplex in its complete functioning state. This breakthrough provides a deeper understanding of the organization of these complex membranes, which are essential for plant growth and movement.
A study led by the University of Leeds has identified a resistance protein in bacteria that allows them to survive chlorhexidine, an antiseptic commonly used in hospitals. The discovery is critical for developing new chemicals to combat superbugs, which pose a catastrophic threat to the medical system.
Researchers at the University of Toronto have developed a series of techniques to create efficient iron-based catalysts for producing alcohols and amines used in the drug and perfume industry. The new process replaces rare elements with abundant iron, making it safer, more economical, and environmentally friendly.
Researchers have determined the high-resolution atomic structure of E2 envelope glycoprotein, a crucial part of the hepatitis C virus. The new data reveal unexpected structural features and should greatly speed efforts to make an effective hepatitis C vaccine.
A new study found that newlyweds' gut-level negative evaluations of their partners predict future marital happiness. The study, led by Florida State University researcher James K. McNulty, involved 135 heterosexual couples and found that conscious attitudes did not always reflect automatic feelings about the marriage.
A study led by Boston University School of Medicine researchers reveals that methylation signaling regulates VEGFR-2, leading to angiogenesis and tumor growth. This finding provides a promising new approach to blocking cancer growth by targeting this biochemical process.
Researchers found that males secrete signaling molecules that shorten the lifespan of hermaphroditic females by more than 20%. The effect persists even when genders are separated or females are sterile, indicating it's not due to physical stress or energy demands. Pheromone production is also linked to male-induced demise.
Scientists have successfully replicated nonenzymatic RNA copying inside fatty acid vesicles, overcoming a critical problem in creating primitive synthetic cells. The team used citrate as a chelator to protect the membrane from degradation by magnesium ions, allowing RNA chemistry to proceed.
Researchers discovered epigenetic differences in colon cancer cells that render them resistant to chemotherapy drugs. The findings suggest that the inactivation of a specific gene may be responsible for this phenomenon.
A study by University of Nottingham researchers found that Malaysian drivers are less likely to identify situations as dangerous and react to them later than British drivers. The study suggests that hazard perception tests may need to be adapted for developing countries where road safety is a primary concern.
Researchers found that high cholesterol's metabolite, 27HC, mimics estrogen to drive breast cancer growth. Statins appear to reduce this effect, suggesting a link between dietary changes and breast cancer prevention. Human breast tumors express the enzyme making 27HC, which can promote tumor growth.
Male fruit flies that expect sex but don't receive it experience rapid decreases in fat stores, resistance to starvation, and more stress. Mating partially reverses the negative effects on health and aging. The study provides new insights into how sensory perception and physiological state are integrated in the brain.
A recent study highlights the association between poor oral health and increased risk of cardiovascular disease, particularly among those consuming high amounts of sugar in junk foods. Experts recommend reducing fizzy drink intake and improving oral hygiene to prevent heart problems later in life.
Researchers at CNIO have created a massive database of interactions between drugs and proteins, known as FireDB. The database includes over 16,600 compounds and 500,000 interactions, providing valuable information for the study of cancer and therapeutic agents.
A new study published in PLOS ONE suggests that a Mediterranean diet without breakfast, but with a large meal at lunch, may be the most beneficial for patients with diabetes. The study found that this diet approach reduced blood glucose levels and triglycerides compared to low-fat and low-carbohydrate diets.
