Farmers around the world are struggling with the impact of climate change, financial pressures and depleted soil—and industry experts say bringing consumers closer to the people who produce their food could provide a solution.
Medical Xpress / The anti-aging effects of exercise, without exercise: Self-contracting muscle implants give mice a boost
Exercise does more than keep our minds and bodies healthy. It also protects us against the effects of aging. Scientists have developed self-contracting mini-muscle implants that grow their own blood supply and mimic the biological ...
Phys.org / Dolphin-feeding tourism contributes to predicted dolphin decline
A study published in the journal Oikos, titled "Forecasting the impact of food-provisioning and other stressors on a marine top-predator population," found that without protective management, the Indo-Pacific bottlenose dolphin ...
Phys.org / Why some earthquakes caused by fracking come with warning signs
Fracking, the injection of high-pressure fluid to fracture rock and release oil or gas, can trigger earthquakes. While some sites generate small tremors beforehand that may provide an early warning, others produce few or ...
Medical Xpress / One flash of red light could check health of bioprinted tissue and implants
Using 3D printers to create complex structures from biocompatible materials that can include living cells has the potential to revolutionize medicine. This process—3D bioprinting—has powered breakthroughs in tissue engineering, ...
Phys.org / Even ancient bacteria possessed intercellular communication structures like humans today, study finds
Communication between cells in plants, animals and humans takes place via specialized connecting structures. An international team led by biologists from Heinrich Heine University Düsseldorf (HHU) and involving the University ...
Phys.org / Bumblebees may self-medicate when exposed to fungal infections
There is an old saying that nature is the best medicine, and it turns out bumblebees might agree. A new study published in the journal Royal Society Open Science suggests that buff-tailed bumblebees (Bombus terrestris) may ...
Phys.org / Milky Way's own gravity can mimic dark matter clues, stellar stream simulations suggest
Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like planets in our solar ...
Phys.org / Screening tool amplifies tiny changes in protein levels within cells
Imagine a brain teaser where the challenge is to spot the difference between two nearly identical sandcastles. The only difference? The removal of three grains of sand. Scientists face a similarly exasperating challenge when ...
Medical Xpress / Stress and depression, not heart damage, may drive long-term breast cancer fatigue
For breast cancer survivors, new research shows that feelings of depression and perceptions of psychological stress make the biggest difference in whether they experience fatigue up to two years after chemotherapy started.
Phys.org / 9/11 responders passed effects of trauma to their children, study finds
Although it's been 25 years since the World Trade Center collapsed after terrorists flew commercial airplanes into each of the center's two towers, the trauma experienced by many first responders and recovery workers is still ...
Medical Xpress / How HIV affects the eyes of aging adults
Older adults with well-controlled HIV may have a higher prevalence of certain eye conditions, particularly dry eye, compared with similar adults without HIV, according to a new study led by a University of Colorado Anschutz ...
