MIT researchers have come up with a new approach to transparent displays that could have significant advantages over existing systems for certain kinds of applications: wide viewing angle, simplicity of manufacture, and potentially low cost and scalability.

Transparent displays have a variety of potential applications — such as the ability to see navigation or dashboard information while looking through the windshield of a car or plane, or… read more

A carbon nanotube sponge capable of soaking up water contaminants such as fertilizers, pesticides and pharmaceuticals more than three times more efficiently than previous efforts has been presented in a new study published January 17 in IOP Publishing’s journal Nanotechnology.

The carbon nanotube (CNT) sponges, uniquely doped with sulphur, also demonstrated a high capacity to absorb oil, potentially opening up the possibility of using the material in… read more

Tiny swimming ‘biobots’ propelled by heart cells or magnetic fields

January 21, 2014

Sperm attack

University of Illinois engineers have developed tiny “bio-bot” hybrid machines that swim like sperm, the first synthetic structures that can traverse the viscous fluids of biological environments on their own, according to the engineers.

The devices are modeled after single-celled creatures with long tails called flagella — for example, sperm. The researchers begin by creating the body of the bio-bot from a flexible polymer. Then they culture heart cells… read more

Cosmic web imaged for the first time

Astronomers have discovered a distant quasar illuminating a vast nebula of diffuse gas, revealing, for the first time, part of the network of filaments thought to connect galaxies in a cosmic web.

Researchers at the University of California, Santa Cruz led the study, published January 19 in Nature.

Using the 10-meter Keck I Telescope at the W. M. Keck Observatory in Hawaii, the researchers detected a… read more

Have you ever Googled for an online diagnosis before visiting a doctor? If so, you may have helped provide early warning of an infectious disease epidemic.

In a new study published in Lancet Infectious Diseases, Internet-based surveillance has been found to detect infectious diseases such as Dengue Fever and Influenza up to two weeks earlier than traditional surveillance methods, according to Queensland University of Technology (QUT) research… read more

DOE Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have discovered that sodium bismuthide can exist as a form of matter called a “three-dimensional topological Dirac semi-metal” (3DTDS).

“A 3DTDS is a natural three-dimensional counterpart to graphene with similar or even better electron mobility and velocity,” says Yulin Chen, a physicist with Berkeley Lab’s Advanced Light Source (ALS) when he initiated the study that led to this discovery,… read more

BYU engineer Dah-Jye Lee has created an algorithm that can accurately identify objects in images or video sequences — without human calibration.

“In most cases, people are in charge of deciding what features to focus on and they then write the algorithm based off that,” said Lee, a professor of electrical and computer engineering. “With our algorithm, we give it a set of images and let the… read more

MIT neuroscientists have found that the human brain can process entire images that the eye sees for as little as 13 milliseconds — the first evidence of such rapid processing speed.

That speed is far faster than the 100 milliseconds suggested by previous studies. In the new study, which appears in the journal Attention, Perception, and Psychophysics, researchers asked subjects to look for a particular type of… read more

Google’s smart contact lens project could allow diabetics to track glucose levels automatically

January 17, 2014

To help people with diabetes as they try to keep their blood sugar levels under control, Google is testing a smart contact lens designed to measure glucose levels in tears.

It uses a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material, according to Google Official Blog.

People with diabetes must still prick their finger and test… read more

Evidence that photosynthesis efficiency is based on quantum mechanics

Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous theoretical evidence of quantum effects in photosynthesis, published in the journal Nature Communications (open access).

The majority of light-gathering macromolecules are composed of chromophores (responsible for the color of molecules) attached to proteins, which carry out the first step of photosynthesis, capturing… read more

Directly imaging and analyzing planets around other stars: first light

Early images are almost a factor of 10 better than the previous generation of instruments

After nearly a decade of development, construction and testing, the world’s most advanced instrument for directly imaging and analyzing planets orbiting around other stars is pointing skyward and collecting light from distant worlds.

“Even these early first-light images are almost a factor of 10 better than the previous generation of instruments. In one minute, we were seeing planets that used to take us an hour to detect,” says Bruce… read more

Discovery of quantum vibrations in microtubules inside brain neurons corroborates controversial 20-year-old theory of consciousness

A review and update of a controversial 20-year-old theory of consciousness published in  Elsevier’s Physics of Life Reviews (open access) claims that consciousness derives from deeper-level, finer-scale activities inside brain neurons.

The recent discovery of quantum vibrations in microtubules inside brain neurons corroborates this theory, according to review authors Stuart Hameroff and Sir Roger Penrose. They suggest that EEG rhythms (brain waves) also derive from deeper level… read more

Life on other planets could be far more widespread

Some of it could be underground

Earth-sized planets can support life at least ten times farther away from stars than previously thought, according to researchers at the University of Aberdeen and the University of St Andrews.

A new paper published in Planetary and Space Science claims cold rocky planets previously considered uninhabitable may actually be able to support life beneath the surface.

The team challenges the traditional “habitable zone” or “Goldilocks zone”… read more
