Phys.org / Fluorescent nanosensors help distinguish between healthy and diseased immune cells in blood samples
Researchers at Karolinska Institutet and SciLifeLab have developed a new method to analyze the condition of immune cells in the blood. The method has been tested on patients with atherosclerosis and can distinguish their ...
Medical Xpress / Why the same antibiotic can cure one infection but fail in another
A group of researchers has uncovered why one common antibiotic works for urinary tract infections but often fails elsewhere, offering greater insight into how the body's own chemistry can determine whether antibiotics succeed ...
Phys.org / Sizing errors can hide true nanoparticle behavior
Nanoscience, which studies small objects, has a big problem. According to a team of scientists at the National Institute of Standards and Technology (NIST), the field confronts a pervasive data analysis error that can give ...
Medical Xpress / Bacterial supplements may boost female fertility
As women get older, their uterine environment changes. This includes a decrease in a beneficial bacterium called Lactobacillus gasseri, which may make conception—whether natural or via in vitro fertilization—difficult. In ...
Medical Xpress / Map of tonsil's genetic 'spaghetti' yields insights into immunity
About 2 meters (6.6 feet) of genetic material must fit into the nucleus of each of most of our trillions of cells, coiling and winding to form what looks like a tangled mess. But when genes are used, how they are used and ...
Phys.org / Pumas make roads safer for drivers by changing prey behavior patterns
Living among large predatory carnivores could actually make you safer. A study published in the journal Current Biology found that pumas—wild cats also known as mountain lions, cougars or panthers—change deer behavior, leading ...
Phys.org / Seven new diamond frog species reveal Madagascar's hidden amphibian diversity
An international team of scientists has described seven new species of Madagascar's elusive diamond frogs (Rhombophryne), revealing that one of the island's most mysterious groups of amphibians is even more diverse than previously ...
Medical Xpress / Study uses living human brain tissue to map how electric stimulation affects neurons and genetic activity
Neurons that once encoded a person's memories are now helping researchers identify genetic targets that may one day help preserve memory and slow cognitive decline in others.
Phys.org / Little-known protein helps the body restrain scar-forming signals
U.K. and U.S. scientists have uncovered an important piece of the puzzle in the signaling pathway that causes damaging scar tissue to build up in the body, raising hopes for future treatments. A team from the University of ...
Phys.org / High-coverage ancient genomes reveal prehistoric population histories of Japan
A research team led by Koji Ishiya of Kanazawa University reconstructed exceptionally high-coverage genomes from two ancient individuals in Japan: IY1, a woman from the Initial Jomon period who lived about 8,300 years ago, ...
Phys.org / Life speaks one universal language to activate genes: It speaks many more to silence them
The signals that cells use to switch genes on have remained almost unchanged across 2 billion years of evolution, but the ones used to switch genes off vary dramatically from one branch of life to another, according to a ...
Phys.org / Seaweed-derived coating keeps strawberries fresher than a fridge
University of British Columbia researchers have developed an edible, seaweed-derived coating that can keep strawberries fresh for at least four days at room temperature, outperforming uncoated berries stored in the refrigerator.
