Phys.org / Discovery of antimicrobial peptides in ant venom has far-reaching implications
In addition to serving as biochemical weapons for offense and defense, the venoms produced by ants in the subfamily Formicinae also fulfill additional roles. For example, the ants use it to protect their nests from pathogens. ...
Medical Xpress / The rules neurons follow to make sense of what we see
Even in the primary visual cortex, a brain region named for its specialized role in processing basic features of what the eyes see, not every neuron ends up answering the call to process properties of visual input. Maybe ...
Medical Xpress / Nearly half of U.S. women have financial concerns that could impact health care, report suggests
Nearly half of U.S. women are more concerned about affording health care than about developing serious diseases, according to a national report released by the Cleveland Clinic.
Phys.org / How ion channels inside cells manipulate the cytoskeleton
Microglia, the immune cells that protect the brain, are thought to maintain a healthy brain environment by removing unwanted substances through dynamic remodeling of the actin cytoskeleton, the cell's internal framework. ...
Phys.org / Mathematicians prove existence of Kaleidocycles then unlock their exact motion
Kaleidocycles are flexible polyhedral structures composed of rigid tetrahedra connected along their edges to form rotating rings. Each tetrahedron is a solid 3D polygon with four triangular faces (like a triangular pyramid), ...
Medical Xpress / Genes give neurons a 'GPS' to form the brain's neural circuits, scientists show
How complex neural circuits are genetically designed and wired is a fundamental question in neuroscience. Scientists have shown for the first time that genes encode a "wiring map" that guides neurons to connect with the correct ...
Medical Xpress / Dinner at the door: Convenient healthy meals may ease depression symptoms
Making healthy meals more convenient through meal delivery services could improve depressive symptoms by removing some of the daily burdens that often accompany depression, according to a new University of Michigan study.

Phys.org / Large-scale eDNA survey reveals hidden factors that affect regional fish communities
As climate change and human activities continually ramp up, fish are forced to find ways to adapt. As fish move around to find more suitable habitats as ocean conditions shift, regional fish distributions change—which can ...
Phys.org / Sex-related differences in hoverfly eyes give insight into their aerodynamic powers
Many male hoverflies have bigger eyes than females, giving them the advantage of better optics and faster photoreceptors in high-speed pursuits to find a preferred partner to breed.
Medical Xpress / The liver's immune cells might be the key to curing hepatitis B
Fifteen years ago, doctors in Europe noticed a remarkable thing happening in people with chronic hepatitis B infections. When patients went off their medications, the virus started to come back—and then some of the patients ...
Medical Xpress / Contact lenses treat depression in mice as effectively as anti-depressant medication
Materials scientists have designed brain-stimulating contact lenses that are as effective as Prozac at treating depression in mice. The soft, transparent contact lenses have in-built electrodes that deliver mild electrical ...
