Phys.org / Seeing how atoms vibrate at the Ångström scale
Probing the vibration of atoms provides detailed information on local structure and bonding that define material properties. Tip-enhanced Raman spectroscopy (TERS) offers extremely high resolution to probe such vibrations. ...
Phys.org / Stiff gels slow germs: Mapping the hydrogel properties that control bacterial growth
Hydrogels are soft, jelly-like materials that can absorb large amounts of water. They are widely used in medical technologies such as contact lenses and wound dressings, and are also a staple of laboratory research, where ...
Phys.org / What honey bee brain chemistry tells us about human learning
A multi-institutional team of researchers led by Virginia Tech's Fralin Biomedical Research Institute at VTC has for the first time identified specific patterns of brain chemical activity that predict how quickly individual ...
Medical Xpress / Digital twin reveals how eye cells lose their organization in leading cause of vision loss
National Institutes of Health (NIH) researchers have developed a digital replica of crucial eye cells, providing a new tool for studying how the cells organize themselves when they are healthy and affected by diseases. The ...
Medical Xpress / A hidden neuron 'gatekeeper' may shape Alzheimer's buildup of amyloid-beta
Brain cells are constantly swallowing material from the fluid that surrounds them—signaling molecules, nutrients, even pieces of their own surfaces—in a process known as endocytosis that is essential for learning, memory ...
Phys.org / Widespread loss of marine sponges possible if heat waves intensify by just 1°C
New research shows the effects of marine heat waves on sponges could be much more severe as temperatures rise. More intense marine heat waves as a result of climate change could lead to the mass loss of a sponge species found ...
Medical Xpress / Minimally invasive surgery restores active dad's mobility
Stretching at the gym, AJ Starsiak felt an alarming pop in his back. Starsiak shrugged it off. An active 39-year-old father of two who plays softball and ice hockey, he was no stranger to minor injuries.
Phys.org / Mars' 'young' volcanoes prove more complex than scientists once thought
What appears to be a single volcanic eruption is often the result of complex processes operating deep beneath the surface, where magma moves, evolves, and changes over long periods of time. To fully understand how volcanoes ...
Medical Xpress / Doctors discover a simple method to predict the risk of brain tumor recurrence
Meningioma is the most common type of brain tumor. It does not develop in the brain tissue itself, but on the inside of the meninges, the membranes that surround the brain. In most cases, a meningioma is benign. However, ...
Phys.org / 7,000-year-old deer antler headdress from Eilsleben illustrates contact between hunter–gatherers and early farmers
Central Germany is among the regions where, as early as the mid-6th millennium BC, farmers displaced the Mesolithic hunter–gatherers from the fertile loess soils. Soon after this migration, however, exchange began between ...
Medical Xpress / HPV cancer vaccine slows tumor growth and extends survival in preclinical model
Throughout the past decade, Northwestern University scientists have uncovered a striking principle of vaccine design: Performance depends not only on vaccine components but also on vaccine structure. After proving this concept ...
Phys.org / Bird guano powered rise of Chincha Kingdom in Peruvian Andes, archaeologists find
New archaeological evidence reveals that seabird guano—nutrient-rich bird droppings—was not only essential to boosting corn yields and supercharging agriculture in ancient Peru, but it may have been a driving force behind ...
