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, […]

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 […]

Hubble Views Dwarf Galaxy NGC 5477

NGC-5477

Created from a combination of exposures from Hubble’s Advanced Camera for Surveys, this new Hubble image shows dwarf galaxy NGC 5477 and the clouds of glowing hydrogen gas in which new stars are forming. The constellation of Ursa Major (The Great Bear) is home to Messier 101, the Pinwheel Galaxy. Messier 101 is one of […]
