Engineers combine layers of flexible materials into pressure sensors to create a wearable heart monitor thinner than a dollar bill. The skin-like device could one day provide doctors with a safer way to check the condition of a patient’s heart.
Zhenan Bao, a professor of chemical engineering at Stanford, has developed a heart monitor thinner than a dollar bill and no wider than… read more
When the hippocampus, the brain’s primary learning and memory center, is damaged, complex new neural circuits — often far from the damaged site — arise to compensate for the lost function, say life scientists from UCLA and Australia who have pinpointed the regions of the brain involved in creating those alternate pathways.
The researchers found that parts of the prefrontal cortex take over when the hippocampus is… read more
By combining existing genetic “parts,” or engineered genes, in novel ways, MIT engineers have transformed bacterial cells into living calculators that can compute logarithms, divide, and take square roots, using three or fewer genetic parts.
The circuits perform those calculations in an analog fashion by exploiting natural biochemical functions that are already present in the cell rather than by reinventing them with digital logic.… read more
Google, in partnership with NASA and the Universities Space Research Association (USRA), has launched an initiative to investigate how quantum computing might lead to breakthroughs in machine learning, a branch of AI that focuses on construction and study of systems that learn from data..
The new lab will use the D-Wave Two quantum computer.A recent study (see “Which is faster:… read more
A computer science professor at Amherst College has conducted experiments to test the speed of a quantum computing system (from D-Wave) against conventional computing methods.
“Ours is the first paper to my knowledge that compares the quantum approach to conventional methods using the same set of problems,” says Catherine McGeoch, the Beitzel Professor in Technology and Society (Computer Science) at Amherst.
McGeoch,… read more
It was hailed some 15 years ago as the great hope for a biomedical revolution: production of patient-specific embryonic stem cells (ESCs) from cloning to create perfectly matched tissues that would someday cure ailments ranging from diabetes to Parkinson’s disease.
Since then, the approach has been enveloped in ethical debate. A paper published by Shoukhrat Mitalipov, a reproductive biology specialist at the Oregon Health and Science University in Beaverton,… read more
University of California, Berkeley researchers have developed a device that uses wireless signals to provide real-time, non-invasive diagnoses of brain swelling or bleeding.
The device analyzes data from low energy, electromagnetic waves, similar to the kind used to transmit radio and mobile signals. It could potentially become a cost-effective tool for medical diagnostics and to triage injuries in areas where access to medical care, especially medical imaging, is… read more
On Wednesday, Google unveiled a new Google Maps, by far the biggest redesign since it introduced Maps eight years ago, The New York Times reports.
When users who are logged into Google visit Maps, they will see the places they frequently visit highlighted, like restaurants, museums and their home. Google learns the places they go by drawing information from all of Google’s services — including search and… read more
Google revealed some new search tools on Wednesday at I/O, its annual developers conference, The New York Times reports. Taken together, they are another step toward Google’s trying to become the omnipotent, human-like “Star Trek” search engine that its executives say they want it to be.
When people ask Google certain questions, it will now try to predict the person’s follow-up questions and answer them, too. Ask… read more
University of Washington engineers have demonstrated in mice a way to prevent failure of implants and prostheses, using a synthetic hydrogel biomaterial that fully resists the body’s natural attack response to foreign objects.
Medical devices such as artificial heart valves, prostheses and breast implants could be coated with this polymer to prevent the body from rejecting an implanted object.
How… read more
A drug developed by scientists at the Salk Institute for Biological Studies, known as J147, reverses memory deficits and slows Alzheimer’s disease in aged mice following short-term treatment.
The findings may pave the way to a new treatment for Alzheimer’s disease in humans.
“J147 is an exciting new compound because it really has strong potential to be an Alzheimer’s disease therapeutic by slowing disease progression… read more
The frontal lobes in humans vs. other species are not — as previously thought — disproportionately enlarged relative to other areas of the brain, according to a study by Durham and Reading universities.
It concludes that the size of our frontal lobes — an area in the brain of mammals located at the front of each cerebral hemisphere — cannot solely account for humans’ superior cognitive… read more
A world-first completed clinical study by an Australian team has found Kava, a medicinal South Pacific plant, significantly reduced the symptoms of people suffering anxiety.
The study, led by the University of Melbourne, revealed Kava could be an alternative to pharmaceutical products for the hundreds of thousands of Australians who suffer from generalized anxiety disorders (GAD)
“In this study we’ve been able to show… read more
Researchers at BGI (formerly the Beijing Genomics Institute) in Shenzhen, China, the largest gene-sequencing facility in the world, are searching for the quirks of DNA that may contribute to genius in an ethically controversial study.
They are scouring the genomes of 1,600 U.S. adolescents who signed up for the Study of Mathematically Precocious Youth (SMPY) in the 1970s, Nature News reports.
Some geneticists say that the… read more
Tiny, intelligent things all around us, coordinating their activities. There are few more appropriate guides to this impending future than Alex Hawkinson, whose DC-based startup, SmartThings, has built what’s arguably the most advanced hub to tie connected objects together, Wired reports.
At his house, more than 200 objects, from the garage door to the coffeemaker to his daughter’s trampoline, are all connected to his SmartThings system.… read more
