Astronomers have redefined one of the most commonly used stellar distances, the astronomical unit (AU). Based on the rough distance from Sol to Earth, AU has been transformed from a confusing equation to simple number. Astronomers had adopted this simplification at this summer’s past International Astronomical Union’s meeting in Beijing, China, making the astronomical unit […]

NASA Data Suggests “Dry Ice” Snowfall on Mars

Orbiter detected carbon-dioxide snow clouds on Mars

Using data from NASA’s Mars Reconnaissance Orbiter, scientists have detected carbon-dioxide snow clouds on Mars and evidence of carbon-dioxide snow falling to the surface. Pasadena, California — NASA’s Mars Reconnaissance Orbiter data have given scientists the clearest evidence yet of carbon-dioxide snowfalls on Mars. This reveals the only known example of carbon-dioxide snow falling anywhere […]

UCLA Study Shows How a Common Gene Mutation Affects Kids with ASD

how common gene mutation affects kids with autism

A new study from UCLA scientists reveals how a mutation in the MET receptor tyrosine kinase gene affects kids with autism spectrum disorders, showing for the first time that the “C” variant, which reduces MET protein expression, specifically impacts the network of connections among different areas of the brain involved in social behavior, including recognizing […]

Ultrasound Waves Improve Skin’s Permeability to Drugs

Using ultrasound waves to boost skin’s permeability to drugs

A team of engineers from MIT found a way to enhance the permeability of skin to drugs by applying two separate beams of ultrasound waves, one of low frequency and one of high frequency, possibly paving the way for noninvasive drug delivery methods. Using ultrasound waves, MIT engineers have found a way to enhance the […]

cat-harbors-ndm-1

The Indian superbug NDM-1, which has a gene that encodes an enzyme conferring resistance to almost all known antibiotics, has been found in the USA in a household cat. Pets with NDM-1 could be a dangerous vector of infection, since people have close contact with them. The finding was announced by Rajesh Nayak, a research […]

Human Embryonic Stem Cells Restore Partial Hearing in Gerbils

stem-cells-differentiated-auditory-neurons

There are more than 275 million people that have moderate to profound hearing loss, and many are caused by a breach in the connection between the inner ear and the brain. Researchers have discovered that a key component in repairing the auditory nerve is human embryonic stem cells. The scientists published their findings in the […]

Synchronization in a Decentralized Power Grid

How robust is the power grid

As large power plants are replaced by multiple photovoltaic panels on roofs, biogas systems on fields, and wind turbines on hills and offshore, scientists now believe that synchronization in a decentralized power grid may actually be easier than previously thought, as a grid with many generators finds its own shared rhythm of alternating current. Renewable […]

Remote Controlled Cockroach Biobots

cockroach-biobot-remote-control

Madagascar hissing cockroaches aren’t something pleasant to see, but if you’re trapped under a collapsed building, then cockroach biobots might help come to your rescue. The researchers state that the trick to cockroach biobots is to fire wireless signals at the roach’s antennae and other sensory organs to guide it towards a desired location. The […]
