Phys.org / Is feeding birds and other wildlife a good thing or a bad thing?
Is that bird feeder in your backyard really helping nature? How about feeding the chipmunks that come to your patio? Or handouts to wildlife in their natural environment, far from human habitation?
Phys.org / Video game experiment reveals people value feeding their neighbors—even at a cost to themselves
For many people, the allure of video games is that they offer players a chance to enter a world very different from their own: everything from fighting dragons in a mythical realm to racing cars on an obstacle-filled roadway. ...
Medical Xpress / How stress hormone receptors alter the brain and behavior: Zebrafish study provides insights
Stress, the body's natural response to different types of challenges and daily problems, is an inherently harmless state experienced by most people worldwide. While short-term stress is a common experience and can even be ...
Phys.org / Bulk inorganic crystals grown from water emit 'handed' light
Researchers at Kumamoto University have discovered that a purely inorganic crystal grown from water solution can emit circularly polarized light, a special form of light whose "handedness" distinguishes left from right.
Phys.org / A centuries-old debate on how reptiles keep evolving skin bones is finally settled
Our bones did not begin deep inside the body. They started in the skin, not long after the first complex animals took shape.
Medical Xpress / Reprogrammed skin cells shed light on HIV-related cognitive impairment
Using participant skin cells reprogrammed into neurons, Weill Cornell Medicine researchers have identified genetic signatures associated with HIV infection that may contribute to the cognitive impairment that often occurs ...
Medical Xpress / Can biology reveal parental manipulation?
Parental alienation is when one parent manipulates the child into distancing themselves from the other parent. But does this leave detectable biological evidence?
Phys.org / Is California really 100% drought-free for the first time in 25 years? Yes and no: Here's why
For the second time in the past two weeks, the U.S. Drought Monitor, a prominent national report, has classified 100% of California as being drought-free. That's a rating that hasn't occurred in 25 years.

Medical Xpress / Infant gut bacteria may be the key to preventing asthma and allergies
Allergies and asthma affect an increasing number of children worldwide, but now an international research group led by DTU has identified a previously unknown mechanism that can reduce the risk of allergies and asthma later ...
Phys.org / Scientists demonstrate low-cost, high-quality lenses for super-resolution microscopy
Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical components that enable super-resolution imaging, with each lens costing less than $1 to produce. The ...
Phys.org / A tiny mouse hints at why some mammal mothers may benefit from choosing more than one father
Many animals do something that still surprises researchers: females often mate with more than one male. This behavior—polyandry—has long raised a blunt question. Why divide offspring among multiple fathers, and does it ...
