Neuroscientists at The University of Texas Health Science Center at Houston (UTHealth) have reversed memory loss in sea-snail nerve cells by by retraining them on optimized training schedules.
This may be a major step in helping people with memory loss tied to brain disorders such as Alzheimer’s disease, the researchers suggest.
“Although much works remains to be done, we have demonstrated the feasibility of… read more
A spray-on mixture of carbon nanotubes and ceramic that has unprecedented ability to resist damage while absorbing laser light has been demonstrated by researchers from the National Institute of Standards and Technology (NIST) and Kansas State University.
Coatings that absorb as much of the energy of high-powered lasers as possible without breaking down are essential for optical power detectors that measure the output… read more
A new keyboard called KALQ that enables faster thumb-typing on touchscreen devices has been created by a research team at the Max Planck Institute for Informatics, the University of St Andrews, and Montana Tech.
They used computational optimization techniques and a model of thumb movement to search among millions of potential layouts before identifying one that yields superior performance.
A user study found… read more
Computerized fabrics that change their color and shape in response to movement are being developed by Joanna Berzowska, professor and chair of the Department of Design and Computation Arts at Concordia University.
The interactive electronic fabrics harness power directly from the human body, store that energy, and then use it to change the garments’ visual properties.
“Our goal is to create garments that can transform in… read more
Today we have more info about Glass, after Google released the tech specs of its upcoming smartglasses, Gizmag reports.
The most important part of Glass is its display. Google vividly describes the tiny high-res screen as “the equivalent of a 25-inch high definition screen from eight feet away.”
Glass shoots 5-megapixel stills and 720p videos. Google had already revealed that Glass delivers audio via bone conduction.… read more
Purdue University researchers are developing a new type of semiconductor technology for future computers and electronics that could replace today’s CMOS (complementary metal oxide semiconductor) transistors.
It’s based on “two-dimensional nanocrystals” layered in sheets less than one nanometer thick.
The layered structure is made of a material called molybdenum disulfide, which belongs to a new class of semiconductors — metal di-chalogenides.
The nanocrystals are… read more
At a first-of-its-kind meeting, held on April 9–11 at the University of Cambridge, leading conservationists and synthetic biologists discussed how synthetic biology could be used to benefit the planet, Nature News reports.
Example might include producing heat-tolerant coral reefs, pollution-sensing soil microbes, ruminant gut microbes that don’t belch methane, and helping frogs to overcome chytridiomycosis, the fungal disease threatening amphibians worldwide that is thought to have contributed to… read more
Researchers at Brigham and Women’s Hospital (BWH) have invented a microneedle adhesive more than 3x stronger than surgical staples for skin graft fixation, inspired by Pomphorhynchus laevis, a spiny-headed worm that lives in the intestines of its hosts, in this case fish.
The worm securely attaches to the host’s intestinal wall by penetrating, and then plumping up its elongated, cactus-like head into the intestinal tissue.… read more
UC Berkeley researchers have uncovered exactly how acute stress — short-lived, not chronic — primes the brain for improved performance.
In studies on rats, Daniela Kaufer, associate professor of integrative biology at the University of California, Berkeley and post-doctoral fellow Elizabeth Kirby they found that significant but brief stressful events caused stem cells in rat brains to proliferate into new nerve cells that,… read more
A brain-training task that increases the number of items an individual can remember over a short period of time may boost performance in other problem-solving tasks by enhancing communication between different brain areas.
The new study is one of a growing number of experiments on how working-memory training can measurably improve a range of skills — from multiplying in your head to reading a complex paragraph.
“Working memory… read more
Princeton University researchers have found that making an erroneous decision is caused by errors, or “noise,” in the information coming into your brain, rather than errors in how your brain accumulates or processes that information.
The researchers separated sensory inputs from the internal mental process. ”To our great surprise, the internal mental process was perfectly noiseless. All of the imperfections came from noise in the sensory… read more
Researchers at the Stanford University School of Medicine have succeeded in transforming skin cells directly into oligodendrocyte precursor cells (OPCs), the cells that myelinate nerve cells (wrap them in the insulating myelin sheaths that help nerve signals propagate) and would work successfully when transplanted into the brains of mice with a myelin disorder.
The current research was done in mice and rats. If the approach also works… read more
Bioengineered rat kidneys developed by Massachusetts General Hospital (MGH) investigators successfully produced urine both in a laboratory apparatus and after being transplanted into living animals.
This is important, cutting-edge research by Mass General, which conducts the largest hospital-based research program in the U.S. On Monday, the hospital received 29 patients, eight in critical condition, victims of Monday’s twin explosions near the finish line… read more
A DNA sequencing system that combines a solid-state nanopore with a technique known as DNA origami for use in DNA sequencing, protein sensing and other applications, has been developed by Dr. Ulrich Keyser of Cambridge University’s Cavendish Laboratory, along with PhD student Nick Bell and other colleagues.
The technology has been licensed for development and commercialization to UK-based company Oxford Nanopore, which is… read more
A new chemical process can transform waste sulfur into a lightweight plastic that may improve batteries for electric cars, reports a University of Arizona-led team.
The new plastic also has other potential uses, including optical uses.
The team has successfully used the new plastic to make lithium-sulfur batteries.
Next-generation lithium-sulfur, or Li-S, batteries based on the plastic will be better for electric and… read more
