Tai chi: an ancient art may work best to prevent falls in old age

Posted by in category: health

(HealthDay)—The ancient practice of tai chi may beat strength training and aerobics for preventing falls among seniors, a new trial shows.

A modified senior-centered tai chi program reduced falls nearly a third better in a head-to-head comparison with an exercise regimen that combined aerobics, strength training and balance drills, the researchers reported.

“This tai chi program better addressed the deficits that were contributing to fall risk,” said senior researcher Kerri Winters-Stone, a professor with the Oregon Health & Science University School of Nursing.

Characteristic patterns of inter- and intra-hemispheric metabolic connectivity in patients with stable and progressive mild cognitive impairment and Alzheimer’s disease

Posted by in categories: biotech/medical, neuroscience

Alzheimer’s disease (AD) is a neurodegenerative disease with characterization of deficits in progressive memory loss, cognitive and behaviour functions. Mild cognitive impairment (MCI) is a predromal stage of AD, displaying cognitive deficit but neither marked functional impairment nor satisfying established clinical criteria for dementia or probable AD. However, not all MCI patients may eventually progress to AD (progressive MCI, pMCI)https://doi.org/10.1016/j.nicl.2013.10.

Therefore, differential diagnosis of MCI types and earlier diagnosis of AD and prediction of disease evolution are difficult

AI Finds More Space Chatter

Posted by in categories: alien life, robotics/AI

Scientists don’t know exactly what fast radio bursts (FRBs) are. What they do know is that they come from a long way away. In fact, one that occurs regularly comes from a galaxy 3 billion light years away. They could form from neutron stars or they could be extraterrestrials phoning home. The other thing is — thanks to machine learning — we now know about a lot more of them. You can see a video from Berkeley, below. and find more technical information, raw data, and [Danielle Futselaar’s] killer project graphic seen above from at their site.

The first FRB came to the attention of [Duncan Lorimer] and [David Narkevic] in 2007 while sifting through data from 2001. These broadband bursts are hard to identify since they last a matter of milliseconds. Researchers at Berkeley trained software using previously known FRBs. They then gave the software 5 hours of recordings of activity from one part of the sky and found 72 previously unknown FRBs.

Scientists: World’s warming; expect more intense hurricanes

Posted by in categories: climatology, computing, sustainability

WASHINGTON (AP) — A warmer world makes for nastier hurricanes. Scientists say they are wetter, possess more energy and intensify faster.

Their storm surges are more destructive because climate change has already made the seas rise. And lately, the storms seem to be stalling more often and thus dumping more rain.

Study after study shows that climate change in general makes hurricanes worse. But determining the role of global warming in a specific storm such as Hurricane Florence or Typhoon Mangkhut is not so simple — at least not without detailed statistical and computer analyses.

Study Suggests Probiotic Bacteria and Superbugs Can Produce Electricity

Posted by in category: futurism

Scientists have discovered that hundreds of bacterial species are capable of producing electricity and could very well be co-opted to create “living batteries.”

While researchers have known that bacteria found in exotic environments like the ocean floor are electrogenic, a new study published in the journal Nature marks the first time scientists have uncovered bacteria interacting with humans are also electrogenic.

These bacteria range from the sort that cause diarrhea to the ones that ferment yogurt. Many fill the human gut, and understanding how these bacteria develop electricity-producing capabilities may reveal how they infect humans — or why they keep us healthy.
