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 […]

New Study Questions Link Between Heavy Cannabis Use and Declining IQ

cannabis-use-and-declining-IQ

A newly published study contradicts the findings from a previous study that suggested that heavy cannabis use as a teenager lowers the persons IQ by middle age. The new study is titled, “Correlations between cannabis use and IQ change in the Dunedin cohort are consistent with confounding from socioeconomic status” and is published in the […]

New Chandra Video Shows the Vela Pulsar in Action

The-Vela-pulsar,-a-neutron-star

A new video from NASA’s Chandra X-ray Observatory shows the Vela pulsar, a neutron star that is 12 miles in diameter, located about 1,000 light-years from Earth, and spins faster than a helicopter rotor. Unlike with some blockbuster films, the sequel to a movie from NASA’s Chandra X-ray Observatory is better than the first. This […]

Study Links Diet Soda with Depression in Older Adults

Diet-SodaTied-to-Depression-Risk-in-Older-Adults

In a new study, scientists found that older adults that drank at least four cups of diet soda a day were 31 percent more likely to report depression than nondrinkers and people who had four or more cups of coffee a day had a roughly 10 percent lower risk of depression versus a nondrinker. TUESDAY, […]

Brazilian Bikini Waxes Aid the Decline of Pubic Lice

Crab-Lice-on-the-decline

It appears that college students, and the general public, have one less sexually transmitted health issue to worry about. A Bloomberg news article is reporting that pubic lice, the crab-shaped insects that have dwell in the human groin area, is on the decline. Scientists have noted that the recent trend in pubic hair removal, such […]

Scientists Develop Glass Nanofibers that are 15 Times Stronger than Steel

strongest,-lightest-glass-nanofibres-in-the-world

Scientists at the Optoelectronics Research Center have developed strong, lightweight silica nanofibers that are 15 times stronger than steel and can be manufactured in lengths potentially of 1000’s of kilometers. The findings could have help transform the aviation, marine and safety industries. The University of Southampton’s Optoelectronics Research Center (ORC) is pioneering research into developing […]

Ingestible Pill-Sized Imaging System Provides 3D View of the Esophageal Wall

endomicroscopy-capsule

Scientists have developed an ingestible pill-sized device that will provide doctors with a 3D view of the esophagus. The capsule is attached to a string-like tether and contains optical frequency domain imaging (OFDI) technology, which uses a rapidly rotating laser tip emitting a beam of near-infrared light and sensors that record light reflected back from […]

Yale Physicists Observe Quantum Information While Preserving its Integrity

observing-quantum-information-while-preserving-its-integrity

Yale physicists have taken a step forward in quantum computing by developing a new, non-destructive measurement system for observing, tracking and documenting all changes in a qubit’s state, thus preserving the qubit’s informational value. Yale University scientists have found a way to observe quantum information while preserving its integrity, an achievement that offers researchers greater […]

US fisheries scientists are claiming that a supervisor threatened to eliminate their research division after the team had produced controversial model predictions of the survival and recovery of the threatened coho salmon (Oncorhynchus kisutch). The threatened O. kisutch reside in the Klamath River Basin in Oregon. The Public Employees for Environmental Responsibility (PEER) filed a complaint […]

Butterflies That Expend The Most Energy Live The Longest

Credit: Pave Väisänen

The more energy a creature uses, the more free radicals and other unstable, cell-damaging molecules its body produces. In many cases this can shorten the lifespan of the animal, but in the case of some butterflies, the opposite seems to be true. The scientists published their findings in The Journal of Experimental Biology¹.The Glanville fritillary […]

Australian Heat Wave Causes Gadgets to Fail

The Australian heat wave is getting so hot that Australia’s Bureau of Meteorology had to add new colors to its weather map. There are parts of Australia that have achieved temperatures above 122ºF (50ºC), temperatures which were off the scale until recently. These new temperature zones will be marked in deep purple and hot pink […]
