A new 3D-printing technology developed by Silicon Valley startup Carbon3D Inc. enables fabricated objects to rise from a liquid media continuously rather than via a series of 2D layers.
Described in the journal Science on Monday March 16, the technology enables ready-to-use products to be made 25 to 100 times faster than other methods, and promises to advance the industry beyond basic prototyping to 3D manufacturing, according… read more
University of Queensland researchers have discovered that non-invasive scanning ultrasound (SUS) technology* can be used to treat Alzheimer’s disease in mice and restore memory by breaking apart the neurotoxic Amyloid-β (Aβ) peptide plaques that result in memory loss and cognitive decline.
The method can temporarily open the blood-brain barrier (BBB), activating microglial cells that digest and remove the amyloid plaques that destroy brain synapses.
Treated… read more

A research team led by Northwestern University nanomedicine expert Chad A. Mirkin and Sergei Gryaznov of AuraSense Therapeutics has shown that spherical nucleic acids (SNAs) can be used as potent drugs to effectively train the immune system to fight disease, by either boosting or dampening the immune response. The initial treatment triggers a cell-specific immune response all over the body.
By increasing the body’s immune response… read more
Carnegie Science researchers have found that the amount of energy that could be generated from solar equipment constructed on and around existing infrastructure in California would exceed the state’s demand by up to five times.
“Integrating solar facilities into the urban and suburban environment causes the least amount of land-cover change and the lowest environmental impact,” according to Carnegie’s Rebecca R. Hernandez (now at… read more
Northwestern University scientists and collaborators have discovered that if the graphene used in experimental fuel cells (used as electric power sources) naturally has a few tiny holes in it, is provides a proton-selective membrane that could lead to improved fuel cells.
A major challenge in fuel cell technology is efficiently separating protons from hydrogen. In a study of single-layer graphene and water, the Northwestern researchers found that… read more

Vanderbilt University researchers have found evidence that awareness or consciousness results from widespread communication across sensory and association areas of the cortex — challenging previous hypotheses that changes in restricted areas of the brain were responsible for producing awareness.
“Identifying the fingerprints of consciousness in humans would be a significant advancement for basic and medical research, let alone its philosophical implications on the underpinnings of the human… read more

Researchers at the Max Planck Florida Institute for Neuroscience and Kanazawa University (Japan) have imaged structural dynamics of living neurons with unprecedented spatial resolution and speed by using a modified atomic force microscope (AFM).
The AFM is a leading tool for imaging, measuring, and manipulating materials with atomic resolution — on the order of fractions of a nanometer — by scanning (“touching” and “feeling”) its surface with… read more
Researchers at the University of California, Berkeley have developed a novel silicon photonic switch — the largest-scale, lowest-energy-loss switch reported to date. It features a switching time of sub-micro seconds and a broad bandwidth of hundreds of nanometers in the electromagnetic spectrum.
Today’s explosion of video and Internet data is driving unprecedented traffic demand within datacenters. With data transfer rates exceeding 100 gigabits-per-second (Gb/s), communication between servers requires optical… read more

UK and Singapore researchers have simulated neural networks and synapses in the brain using optical pulses as information carriers over fibers made from light-sensitive chalcogenide glass.
The research, published in Advanced Optical Materials, has the potential to allow faster and smarter optical neuromorphic (brain-like) computers capable of learning, the researchers say.
Compared to biological systems, today’s computers are “up to a billion times less efficient — simulating 5… read more

Currently, brain stimulation uses pulses of electricity and requires a surgically implanted electrode wired to a power source outside the brain.
In their study, the team injected magnetic iron oxide particles 22 nanometers in diameter into the brain.… read more
Scientists reporting in the ACS journal Environmental Science & Technology have used smartphone and sensing technology to better pinpoint times and locations of the worst air pollution, which is associated with respiratory and cardiovascular problems.
Most such studies create a picture of exposure based on air pollution levels outside people’s homes. This approach ignores big differences in air quality in school and work environments. It also ignores spikes in pollution that… read more
A new ride called Neurosis, based on research from The University of Nottingham, adapts the experience to the rider’s own brain activity. Its world premiere will be at the FutureFest festival taking place in London this weekend.
It draws on research being conducted by performance artist/professor Brendan Walker, a principal research fellow in the University’s School of Computer Science, described as the “world’s only Thrill Engineer” by The… read more

Engineers from the University of California at Berkeley have created an incredibly thin, chameleon-like material that can be made to change color on demand by simply flexing it with a tiny amount of force.
This new material-of-many-colors offers intriguing possibilities for an entirely new class of display technologies, color-shifting camouflage, and sensors that can detect otherwise imperceptible defects in buildings, bridges, and aircraft.
The trick: precisely etching tiny… read more

NASA’s Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter’s largest moon. The subterranean ocean is thought to have more water than all the water on Earth’s surface.
Identifying liquid water is crucial in the search for habitable worlds beyond Earth and for the search of life as we know it.
“A deep ocean under the icy crust of… read more
