Scientists Identify the Characteristic Brain Activities of Lucid Awareness

lucid dreaming

By comparing the brain activity during a lucid dream with the activity measured in a normal dream, scientists at the Max Planck Institute were able to identify the characteristic brain activities of lucid awareness. Which areas of the brain help us to perceive our world in a self-reflective manner is difficult to measure. During wakefulness, […]

A Connection between Volatiles in the Subsurface of Mars and the Impact Process

extremely-detailed-images-of-Mars

While examining detailed images of Martian impact craters from the HiRISE camera, Western University scientists discovered further evidence for the interaction between subsurface volatiles and the impact cratering process. Investigating extremely detailed images of Mars produced by the High Resolution Imaging Science Experiment (HiRISE) camera – the largest-ever carried on a deep space mission – […]

Screening-Engineered Field-Effect Photovoltaics Could Accelerate the Usage of Solar Energy

making high efficiency solar cells from virtually any semiconductor material

Utilizing the electric field effect, a new technology called “screening-engineered field-effect photovoltaics,” or SFPV, reduces the cost and complexity of fabricating solar cells and could provide a cost-effective and environmentally friendly alternative to accelerate the usage of solar energy. A technology that would enable low-cost, high efficiency solar cells to be made from virtually any […]

New Design Makes Previously Inaccessible Proteins Vulnerable to Drugs

undruggable proteins

A team of researchers at Yale University have identified a molecular signal that allows potentially therapeutic proteins to hitch a ride into cells using vesicles, possibly making previously inaccessible proteins vulnerable to drugs. One of the most daunting challenges facing pharmaceutical scientists today are “undruggable proteins” – the approximately 80% of proteins involved in human […]

New System Converts Laser Beam into Controlled Stream of Single Photons

ability to transmit single photons while blocking multiple photons is finally achieved

Using a technique based on electromagnetically induced transparency, MIT and Harvard scientists have achieved the ability to convert a laser beam into a stream of single photons, or particles of light, in a controlled way, possibly opening the door for new quantum devices such as quantum gates. In theory, quantum computers should be able to […]

VLT Reveals that O Stars, Which Drive the Evolution of Galaxies, Don’t Live Alone

Artist’s impression of a vampire star and its victim

Using ESO’s Very Large Telescope to study a sample of 71 O-type single stars and stars in pairs in six nearby young star clusters in the Milky Way, astronomers discovered that 75% of all O-type stars exist inside binary systems and found that the proportion of these pairs that are close enough to interact (through […]

Genetic Cause of Glioblastoma Pinpointed

New Research May Lead to New Treatment for Type of Brain Cancer

A new study from scientists at Columbia University Medical Center pinpoints the genetic cause of glioblastoma and found that drugs that target the protein produced by FGFR-TACC can dramatically slow the growth of glioblastomas in mice. New York, New York — Researchers at Columbia University Medical Center (CUMC) have discovered that some cases of glioblastoma, […]

SLAC Scientists Complete Terahertz Experiment

crystal is used to convert near-infrared laser light into terahertz frequencies

Using a pump-probe technique, scientists at SLAC’s Linac Coherent Light Source used terahertz frequencies of light to change the magnetic state of a sample and then measured those changes with ultrafast pulses from a powerful X-ray laser. Invisible to human eyes, terahertz describes a band of frequencies between microwave and infrared light. These frequencies are […]

Many Nature Reserves Struggling to Sustain Their Original Biodiversity

Averting biodiversity collapse

A new study from a team of international scientists found that deforestation is advancing rapidly in tropical nations and most reserves are losing some or all of their surrounding forest, leaving these nations struggling to sustain their biodiversity. Many of the protected areas in tropical nations are struggling to sustain their biodiversity, according to a […]

H.E.S.S. II Telescope Starts Operation and Detects its Very First Images

H.E.S.S. II telescope

With a 28-meter mirror and a mass of almost 600 tons, the H.E.S.S. II telescope is up and running, detecting its very first images of atmospheric particle cascades generated by cosmic gamma rays and by cosmic rays. On July 26, 2012 the H.E.S.S. II telescope started operation in Namibia. Dedicated to observing the most violent […]

Coniophis Precedens, The Most Primitive Known Snake

Coniophis precedens, most primitive snake

In a published study titled “A transitional snake from the Late Cretaceous of North America,” Yale researchers argue that snakes descend from terrestrial ancestors and emerged once lizards developed long, limbless bodies for burrowing. Researchers at Yale have identified an ancient slithering creature from the time of T. rex as the most primitive known snake, […]

Bacterial Lipids May be a Window into the Geologic Past

gene may help bacteria survive in extreme environments

A newly published study from scientists at MIT describes their discovery of a bacterial gene that may explain the sudden influx of methane-eating bacteria at Deepwater Horizon oil spill and the resulting bacterial lipids that may help identify dramatic changes in oxygen levels over the course of geologic history. In the days following the 2010 […]
