Scientists Work on Developing Computer Chips Made from Nanotubes

carbon-nanotube-chip

Scientists have developed new methods that could result in the production of higher-performance computer chips made from tiny straws of carbon nanotubes. It’s been known for a long time that these nanotubes have electronic properties superior to current silicon-based devices. The scientists published their findings in the journal Nature Nanotechnology. In the past, difficulties of […]

Georgia Aquarium’s Beluga Plan Raises Concerns about Whale Culture

Georgia Aquarium’s controversial plan to move 18 wild beluga whales into captivity

The Georgia Aquarium’s controversial plan to move 18 wild beluga whales into captivity has met with fierce opposition. Opponents state that their capture was inhumane, and could be potentially destructive to a beluga clan. This idea, that whales should be seen in cultural terms, rather than grouped genetically, is new but supported by science. The […]

Largest Catalog Ever of Center of the Milky Way

mosaic of the central parts of the Milky Way

An international team of astronomers created a catalog of more than 84 million stars in the central parts of the Milky Way using a nine-gigapixel image from the VISTA infrared survey telescope at ESO’s Paranal Observatory. This gigantic dataset contains more than ten times more stars than previous studies and is a major step forward […]

Priapulid Worms Highlight Need to Rename A Group of Animals

priapulus-caudatus

A new study on the development of priapulids, known colloquially as penis worms, throws doubt on a feature that has been thought to define one of the largest groups of animals for more than a century. The researchers published their findings in the journal Current Biology. Protostomes have historically been defined by the order in […]

Atomic Level Splicing Further Establishes RNA’s Chemical and Structural Complexity

chemical processes by which RNA carries out the expression of our genes

A newly published paper from researchers at Yale University looks at the process of splicing RNA at the atomic level, establishing RNA’s chemical and structural complexity and showing that it is capable of recruiting diverse metals and orienting them to work with RNA. Scientists at Yale University have described in the greatest detail yet aspects […]

Sediments Suggest Lake Geneva was Devastated by an Ancient Tsunami

Swiss city of Geneva

Over a century after the Romans gave up control of what’s today Geneva, Switzerland, in 563 A.D., a deadly tsunami on Lake Geneva poured over the city’s walls. It originated from a rock fall, near the place where the River Rhône enters the opposite side of the lake. The ensuing tsunami destroyed villages, livestock and […]

New Analysis Method Discovers Millisecond Pulsar via its Pulsed Gamma Radiation

unusual PSR J1311-3430 pulsar system

Using a new a new data analysis method, a team of scientists discovered a millisecond pulsar solely via its pulsed gamma radiation. Pulsars are the compact remnants from explosions of massive stars. Some of them spin around their own axis hundreds of times per second, emitting beams of radiation into space. Until now, they could […]

Study Provides Picture of Human Expansion from Africa

analysis provides fuller picture of human expansion from Africa

A newly published study analyzes genetic and paleoanthropological evidence, showing that today’s human population is the result of a great demographic and geographic expansion that began approximately 45,000 to 60,000 years ago in Africa. A new, comprehensive review of humans’ anthropological and genetic records gives the most up-to-date story of the “Out of Africa” expansion […]
