Marine Bacteria Are Not Homogenous Populations in the Ocean

Bipolar Distribution of Marine Bacteria

New research from scientists at the Marine Biological Laboratory shows that marine bacteria are not just homogenous populations in the ocean and that different bacteria prefer certain temperatures, levels of nutrients, light and salinity. Woods Hole, Massachusetts — In another blow to the “Everything is Everywhere” tenet of bacterial distribution in the ocean, scientists at […]

A Step Towards a Possible Alzheimer’s Vaccine, Researchers Eliminate up to 80% of Senile Plaques in Mice

A Major Step Toward an Alzheimers Vaccine

Researchers at the Université Laval have shown that the molecule MPL (monophosphoryl lipid A) can eliminate up to 80% of the senile plaques associated with Alzheimer’s disease when injected into mice. The researchers believe that it could be administered to Alzheimer’s patients to slow the progression of the disease and to stimulate their natural immunity. […]

Sulfur Cathodes Set a World Record for Energy Storage

World Record Battery Performance

Using a sulfur cathode made of nanoparticles where each tiny sulfur nugget is surrounded by a hard shell of porous titanium dioxide, researchers at Stanford University designed a cathode that can store five times more energy than today’s commercial technology and set a world record for energy storage along the way. SLAC and Stanford scientists […]

New ESO Image Shows Lupus 3

Lupus 3 A Dark Cloud Where New Stars Are Forming

A new image from the European Southern Observatory shows Lupus 3, a cloud that contains huge amounts of cool cosmic dust and a place where new stars are forming. An evocative new image from ESO shows a dark cloud where new stars are forming, along with a cluster of brilliant stars that have already emerged […]

DARPA Demonstrates the Most Complex 2D Optical Phased Array Ever

New 2D Optical Phased Array Technology

By developing new microfabrication techniques, scientists at DARPA have integrated all the components of an optical phased array into a miniature 2-D chip configuration, which may enable advanced LADAR and other defense applications. Most people are familiar with the concept of RADAR. Radio frequency (RF) waves travel through the atmosphere, reflect off of a target, […]

Curiosity Preparing to Drill into First Martian Rock

Flat Lying Rock Selected as the First Drilling Site for NASAs Curiosity Rover

If all goes as planned, NASA’s Curiosity rover may drill its first rock sample in the coming days, providing scientists with important details about the planets past history. Pasadena, California — NASA’s Mars rover Curiosity is driving toward a flat rock with pale veins that may hold clues to a wet history on the Red […]

UCLA Study Shows Childhood Obesity Linked to More Health Problems than Previously Thought

Dr.-Neal-Halfon

By analyzing data on over 43,000 children between the ages 10 and 17, new research from UCLA shows that obese children are at nearly twice the risk of having three or more reported medical, mental or developmental conditions as compared to kids who are not overweight. While a great deal of research on childhood obesity […]

Gene Flow Between Indian Populations and Australia Occurred 4,000 Years Ago

Gene-flow-from-India-to-Australia

A newly published study led by researchers of the Max Planck Institute for Evolutionary Anthropology found evidence that substantial gene flow between Indian populations and Australia occurred about 4,000 years ago. Australia is thought to have remained largely isolated between its initial colonization around 40,000 years ago and the arrival of Europeans in the late […]

Engineers at SEAS Develop a Microelectronic Device that Mimics Functions of Real Cells

Microelectronic-Device-that-Mimics-Functions-of-Real-Cells

Scientists at the Yale School of Engineering & Applied Science have developed a microelectronic device that controls the flow of ions through a nanometer channel that mimics the function of real cells. The construction of artificial cells is a long-sought goal. Researchers from Yale University has made one step toward that goal, by creating a […]

Astronomers Identify the First “Bone” of the Milky Way

Researchers-have-identified-the-first-bone-of-the-Milky-Way

Astronomers from the Harvard-Smithsonian Center for Astrophysics have identified a new structure in the Milky Way: a long tendril of dust and gas that they are calling a “bone.” “This is the first time we’ve seen such a delicate piece of the galactic skeleton,” says the lead author Alyssa Goodman of the Harvard-Smithsonian Center for […]

Astronomers Identify Gas Around Modern Galaxies

Astronomers-find-gas-around-modern-galaxies

Using Hubble’s two ultraviolet spectrographs, researchers from the University of Notre Dame have identified gaseous streams near galaxies through the absorption they imprint on the spectra of distant, bright background quasars. Galaxies have a voracious appetite for fuel — in this case, fresh gas — but astronomers have had difficulty finding the pristine gas that […]

Needle-Like Carbon Nanofibers May Aid in New Drug Delivery Systems

carbon-nanofibers-embedded-in-the-elastic-membrane

In an effort to find a new way to deliver precise doses of drugs to specific targets, scientists at North Carolina State University developed a technique that embeds carbon nanofibers in an elastic silicone membrane, ensuring that the nanofibers are both perpendicular to the membrane’s surface and sturdy enough to impale cells. Researchers at North […]
