Phys.org / Fungi neutralize spruce defense mechanisms with sugar
A research team at the Max Planck Institute for Chemical Ecology discovered a previously unknown strategy by which certain fungi neutralize spruce defense compounds. These fungi are introduced into trees by bark beetles, ...
Phys.org / Ultrathin membranes unlock nano-infrared views of biomolecules in water
Very small biological samples and even individual biomolecules can now be examined under near-physiological conditions with high confidence at the BESSY II infrared beamline using a newly validated and improved technique: ...
Phys.org / Tendon cells can rebound from stiffness when returned to softer tissue-like surroundings
Researchers at Queen Mary University of London are closer to understanding tendinopathy, a common condition that can cause persistent pain and impaired movement in people and many animals.
Phys.org / Bacterial invasion proteins could improve detection of live crop pathogens
Scientists, clinicians, seed companies and others may soon have a new tool in their toolkit for detecting bacterial pathogens, thanks to a new study by researchers in Penn State's College of Agricultural Sciences. The research—published ...
Medical Xpress / Metabolite buildup reveals how aggressive brain tumors activate nearby neurons
Virtually all high-grade, aggressive gliomas in adults accumulate massive amounts of a metabolite called guanidinoacetate (GAA) that overstimulates nearby neurons and promotes tumor growth, according to new research from ...
Phys.org / Light lets microswimmers switch between bacteria-like and algae-like propulsion
Physicists at Leipzig University and Charles University in Prague have developed a method for changing the swimming style of tiny artificial microswimmers in real time. They can make a single microscopic particle switch at ...
Medical Xpress / CAAR T-cell therapy offers a more targeted route for neurological autoimmune diseases
Researchers at DZNE and Charité—Universitätsmedizin Berlin are working on a targeted therapy for neurological autoimmune diseases. So far, they have successfully tested their approach in mouse studies involving two such conditions. ...
Medical Xpress / Binge eating may map onto widespread brain differences in bulimia nervosa
Researchers at the Icahn School of Medicine at Mount Sinai found that individuals with bulimia nervosa have structural differences in brain regions involved in reward and motivation, as well as social and sensory processing, ...
Phys.org / Snow, monsoons and oceans shift Earth's center of mass each year, satellite tracking shows
Seasonal changes redistribute enough water around Earth to shift the planet's center of mass back and forth by fractions of an inch relative to its geometric center. NASA scientists are on the case, tracking the oscillations ...
Phys.org / Iron, sulfur and purple light unlock greener carbon-carbon bond formation
Much of organic chemistry, including the type used to create and alter medicinal drugs, relies on modifying carbon bonds. Rice University's Julian West has been developing a less expensive, faster and more environmentally ...
Phys.org / Roll waves emerge as uniform water flow destabilizes on steep slopes, equations show
When it rains, traveling waves appear on steep asphalt pavement, slowly making their way down the slope. Because these so-called "roll waves" propagate without deforming and are typically characterized by abrupt discontinuities, ...
Medical Xpress / Earliest bladder cancer metastasis may seed later spread
A new study published in Nature has established the foundational landscape of tumor evolution in bladder cancer and differences among cancer subtypes, which could point toward better diagnosis and treatment of the disease.
