Phys.org / Nanoparticles induce neuroregeneration in Alzheimer's disease models
The adult human brain has limited capacity to repair or regenerate neurons lost to Alzheimer's disease, the most common type of dementia. Existing treatments can slow disease progression but do not reverse cognitive decline. ...
Phys.org / Bat DNA adaptations may connect virus defense, longevity and cancer resistance
Bats are anomalies in the mammalian world—they fly, have long lifespans and rarely get cancer. Scientists now suspect the bat immune system enables them to live longer without disease, according to a new study published today ...
Medical Xpress / Study finds gaps in home rehab after joint replacement
Every year, hundreds of thousands of older Americans recover from hip and knee replacement surgery at home. For many, that recovery depends on timely access to physical or occupational therapy after leaving the hospital.
Phys.org / When fruits and veggies are scarce, monkeys hunt for meat
Capuchin monkeys hunt prey when fruits and vegetables become scarce, potentially mirroring the habits of human ancestors, according to a study published in PLOS One by Susana Carvalho (Gorongosa National Park, Mozambique), ...
Phys.org / Butterfly-inspired crystals could enable durable, potentially safer glitter
The next time you need to freshen up the paint on your house or apply a bit of cosmetic glitter before heading out for the night, you might want to give a quick nod to the butterflies fluttering in a nearby garden. Taking ...
Phys.org / Mapping thorium's preferred sites could pave the way for nuclear clocks
For decades, physicists have used a technique called Mössbauer spectroscopy to peer inside solid materials, revealing fine details of their surroundings by studying how their atomic nuclei absorb and re-emit gamma rays.
Phys.org / Bright people know more about wine: How higher intelligence is reflected in deep domain knowledge
Intelligent people tend to perform better at school and at work, as numerous studies have shown. But what happens in domains where incentives such as good grades or financial rewards don't apply and where socioeconomic status ...
Medical Xpress / Hidden hormone spikes may reveal high blood pressure condition
A common but often overlooked cause of high blood pressure may be hiding in plain sight—and data from a pioneering wearable device could hold the key to its earlier diagnosis, according to new research.
Medical Xpress / Gut tissue may retain inflammatory 'memory' for more than a year
Every three to five days, the layer of cells lining our intestines is completely renewed—the fastest turnover rate in the human body. Such rapid regeneration is an absolute necessity for tissue that endures constant mechanical ...
Phys.org / Heat makes emergency rooms busier. Study shows which illness and injuries rise during hot spells
When the temperature heats up, so do emergency rooms, according to a massive study of Chicago hospital and urgent care records, which found increased accidental gunshot wounds, kidney complaints, skin problems, varicose veins ...
Phys.org / For Legionella bacteria, taking over a cell means playing by its rules
When it comes to invading healthy cells, Legionella bacteria rely on blending in rather than breaking in. New research from Van Andel Institute scientists demonstrates how a protein produced by Legionella mimics the behavior ...
Phys.org / Fossil-fuel carbon fingerprint reaches the deep North Atlantic
The use of fossil fuels alters both the concentration and the carbon isotope composition of carbon dioxide in the atmosphere. Since surface water exchanges carbon dioxide with the atmosphere, this also alters the isotopic ...
