Study points to new approach to clearing toxic waste from brain

Posted by in categories: biotech/medical, genetics, neuroscience

Researchers at Washington University School of Medicine in St. Louis have found a new druggable pathway that potentially could be used to help prevent Alzheimer’s dementia.

Amyloid beta accumulation in the brain is the first step in the development of Alzheimer’s dementia. Scientists have poured countless hours and millions of dollars into finding ways to clear amyloid away before cognitive symptoms arise, with largely disappointing results.

In this study, published Aug. 24 in the journal Brain, researchers found a way to increase clearance of waste products from the brains of mice by ramping up a genetic quirk known as readthrough. This same strategy also may be effective for other characterized by the buildup of toxic proteins, such as Parkinson’s disease, the researchers said.

The radical new experiments that hint at plant consciousness

Posted by in category: neuroscience

It’s a wild idea, but recent experiments suggest plants may have the ability to learn and make decisions. Are the claims true and if so, what does it mean for our understanding of consciousness and the human mind?

Humans Vs Robots: Who Should Take Over Space Exploration?

Posted by in categories: robotics/AI, space travel

Since we began space exploration in the mid-20th century, space agencies have relied on sending humans and robots into space. But should we leave space exploration entirely to robots?

Or should we consider sending humans to explore a new space world instead of robots? You are about to find satisfying answers to these curious questions.

Unlike traveling from one destination to another on Earth, exploring space comes with greater responsibilities. Space agencies hoping to explore a new space world must make a lot of planning to guarantee their success.

Supercomputer Emulator—AI’s New Role in Science

Posted by in categories: robotics/AI, science, supercomputing

Bishop: They can still be computationally very expensive. Additionally, emulators learn from data, so they’re typically not more accurate than the data used to train them. Moreover, they may give insufficiently accurate results when presented with scenarios that are markedly different from those on which they’re trained.

“I believe in “use-inspired basic research”—[like] the work of Pasteur. He was a consultant for the brewing industry. Why did this beer keep going sour? He basically founded the whole field of microbiology.” —Chris Bishop, Microsoft Research.

Space Biology, Psychology Studies Help NASA Plan Future Missions

Posted by in categories: biotech/medical, futurism

Life science continued dominating the research schedule aboard the International Space Station on Wednesday to benefit humans living on and off the Earth. The seven Expedition 67 orbital residents explored how living in microgravity affects tissue regeneration, crew psychology, and the human digestion system.

Learning to heal wounds in space is critical as NASA and its international partners plan crewed missions to the Moon, Mars, and beyond. Four station astronauts have been partnering together this week for the skin healing study taking place inside the Kibo laboratory module. Flight Engineers Kjell Lindgren, Bob Hines, and Jessica Watkins, all from NASA, with Samantha Cristoforetti of ESA (European Space Agency), are studying surgical techniques such as biopsies, suture splints, and wound dressing, inside Kibo’s Life Science Glovebox.

Scientists on Earth seek to identify the molecular mechanisms that occur during tissue regeneration in weightlessness. Observations may offer advanced therapies and provide insights into how space-caused accelerated skin aging affects an astronaut’s healing properties. The biomedical experiment may also contribute to better wound healing techniques on Earth.

‘Photonic transistor’ switches light signals instead of electronic signals

Posted by in category: computing

Circa 2014 face_with_colon_three


Electronic transistors, which act as miniature switches for controlling the flow of electrical current, underpin modern-day microelectronics and computers. State-of-the-art microprocessor chips contain several billion transistors that switch signals flowing in electrical wires and interconnects. With increasing data-processing speeds and shrinking chip sizes, however, wires and interconnects waste considerable energy as heat.

One alternative is to replace electrical interconnects with energy-efficient that carry data using . However, a practical analogue of the transistor for optical interconnects does not yet exist. Hence, Vivek Krishnamurthy from the A*STAR Data Storage Institute and co-workers in Singapore and the United States are developing a practical ‘photonic transistor’ for optical interconnects that can control light signals in a similar manner to electronic .
