Medical Xpress / Prototype breath tests spot bacterial infections in minutes
Infectious diseases are a major cause of death worldwide, and diagnosing bacterial infections remains a challenge in medicine. And doing so reliably is more important than ever, given the increasing frequency of antibiotic ...
Medical Xpress / Cellular stress signal found to drive immune exhaustion and weaken cancer therapy
Cancer-fighting T cells do not simply "run out of energy." They are molecularly reprogrammed. For years, mitochondrial dysfunction has been recognized as a hallmark of exhausted T cells in tumors. Yet how metabolic stress ...
Phys.org / Frog-cell 'neurobots' grow self-organized nervous systems and alter gene activity
Biobots, whose growing line of variants started with xenobots, are fascinating tiny self-powered living robots built exclusively using frog embryonic cells. Originally developed in the laboratories of Wyss Institute Associate ...
Medical Xpress / Cholecystokinin, not insulin, may be key hormone in obesity-driven pancreatic cancer
Obesity increases the body's need for insulin, forcing cells in the pancreas known as beta cells to ramp up insulin production to maintain blood sugar levels. Scientists have thought that this excessive insulin secretion ...
Medical Xpress / Early adult drinking linked to middle-age cognitive decline—even after extended abstinence
It's well known that alcohol consumption is an age-old method for coping with stress. But recent research led by the University of Massachusetts Amherst has found that when such self-medication begins in early adulthood, ...
Phys.org / Abalone shells could help trace seafood origins
The rocks beneath our feet are leaving a hidden signature in the shells of marine snails along Australia's ancient coastline, according to new research led by Adelaide University scientists. A study published in Proceedings ...
Medical Xpress / Hope for preventing stomach cancer: Drug candidate proves extremely effective against H. pylori
Researchers at the Technical University of Munich (TUM) have increased the effectiveness of a standard antibiotic by a factor of 60 through targeted chemical modifications. In laboratory and animal studies, the new drug candidate ...
Phys.org / Newly identified disease of corn and sorghum may be mistaken for iron deficiency
A newly identified disease affecting corn and sorghum can closely resemble iron deficiency, potentially leading farmers to apply costly nutrient treatments that do not address the underlying problem. New research published ...
Phys.org / Ultrathin BiFeO₃ breaks the 30 nm limit, delivering fourfold stronger piezoelectricity
Piezoelectric materials, which convert mechanical stress into electricity and vice versa, are essential components in sensors, actuators, and energy-harvesting devices. However, the best piezoelectric materials, such as lead ...
Tech Xplore / Compostable robot endures over 1 million uses before becoming plant food
The rapid proliferation of robots and electronic devices is placing the world under a new and growing environmental burden. According to the United Nations Institute for Training and Research (UNITAR), global electronic waste ...
Medical Xpress / A neuron pair in fruit flies that makes life or death decisions
For the fruit fly, a sense of taste is critical to whether it thrives or dies. The little winged creature has taste organs in its mouthpiece as well as throughout its body, including its legs, abdomen and wing margins. When ...
Phys.org / Magnetic fields guide lab-grown blood vessels into precise patterns for drug testing
Animal studies often fail to predict human tissue responses to new drugs or newly developed therapies. Besides generating tremendous costs for clinical studies, it also raises significant ethical concerns. Therefore, novel ...
