Using machine learning to estimate risk of cardiovascular death
Humans are inherently risk-averse: We spend our days calculating routes and routines, taking precautionary measures to avoid disease, danger, and despair. Still, our measures for controlling the inner workings of our biology can be a little more unruly.
With that in mind, a team from MIT's Computer Science and Artifi
A chameleon-inspired smart skin changes color in the sun
Researchers have taken a page from the chameleon's playbook to develop a flexible smart skin that changes its color in response to heat and sunlight.
Fuel cells developed using nanomaterials are cost effective, efficient
A fuel cell can be built from cheaper, more widely available metals using an atomic-level design that also gives the material long-term stability.
The Swiss Army Knife of gene editing gets new control
When researchers want to edit, activate, or silence a gene in any living organism, from bacteria to humans, they often turn to CRISPR/Cas9, a complex of RNA and protein that can act like a genetic Swiss Army Knife.
Protein batteries for safer, environmentally friendly power storage
Proteins are good for building muscle, but their building blocks also might be helpful for building sustainable organic batteries that could someday be a viable substitute for conventional lithium-ion batteries, without their safety and environmental concerns.
New study reveals carbon nanotubes measurement possible for the first
Scientists have reported a new approach to measuring the conductivity between identical carbon nanotubes which could be used to help improve the efficiency of electrical power cables in the future.
Skin patch could painlessly deliver vaccines, cancer meds, in a minute
Researchers have developed a fast-acting skin patch that efficiently delivers medication to attack melanoma cells. The device, tested in mice and human skin samples, is an advance toward developing a vaccine to treat melanoma and has widespread applications for other vaccines.
'Sniff-cam' to detect disease
Having bad breath can mean someone ate a smelly lunch, but it could indicate that the person is sick. Various scent compounds have been linked to illnesses such as diabetes, lung cancer and Parkinson's disease, leading scientists to develop technology that measures these substances. However, the challenge is creating instrumentation that can detect low, diagnostic levels of these disease biomarkers.
Energy from seawater
Salt is power. It might sound like alchemy, but the energy in places where salty ocean water and freshwater mingle could provide a massive source of renewable power. Researchers have developed an affordable, durable technology that could harness this so-called blue energy.
Artificial throat could someday help mute people 'speak'
Researchers have developed a wearable artificial throat that, when attached to the neck like a temporary tattoo, can transform throat movements into sounds.
New technique could brighten screens, make smartphone batteries last
Our future TV and smartphone screens could have double the energy efficiency, thanks to a technique invented by scientists.
Organic solar cells will last 10 years in space
Over the past two decades, organic solar cells have garnered much attention thanks to their light weight, flexibility and unprecedented energy-to-weight ratios of 10 to 20 W/g, which make them a promising candidate for space applications, although their radiation stability is still poorly
Self-healing DNA nanostructures
DNA assembled into nanostructures such as tubes and origami-inspired shapes could someday find applications ranging from DNA computers to nanomedicine.
Flexible generators turn movement into energy
Wearable devices that harvest energy from movement are not a new idea, but a material created at Rice University may make them more practical.
Octopus-inspired wearable sensor
Wearable electronics that adhere to skin are an emerging trend in health sensor technology for their ability to monitor a variety of human activities, from heart rate to step count. But finding the best way to stick a device to the body has been a challenge.
3D-printed device detects biomarkers of preterm birth
Preterm birth is the leading complication of pregnancy. If doctors had a simple, accurate and inexpensive way to identify women at risk for the condition, they could develop better prevention strategies.
Safer electrochromic inks
Anyone who has a rear-view mirror that automatically dims blue in reaction to annoying high-beam headlights glaring from behind has seen an electrochromic film in action. Chemists have developed a new method to more safely and, by extension, easily produce these shear films, which change their color with the help of a tiny electric current. This could make them available to many industries that have not been able to feasibly use them before.
