A team of geneticists from Trinity College Dublin and archaeologists from Queen’s University Belfast has sequenced the first genomes from ancient Irish humans. The team sequenced the genome of an early farmer woman, who lived near Belfast some 5,200 years ago, and those of three men from a later period, around 4,000 years ago in the Bronze Age, after the introduction of metalworking. Genome analysis helped scientists to state that mass migration of Stone Age farmers from Fertile Crescent and Bronze Age settlers from Eastern Europe was foundation of Celtic population.
A whale got washed ashore on a beach in Wales on Christmas Day, and its carcass may pose a health risk. The Coastguard has warned people to stay away from it. The dead animal was thought to be a Minke whale. It was washed ashore at Dyfi Ynyslas National Nature Reserve.
The animal was discovered on the sands at Ynyslas, nearby Aberdyfi and 8 miles north of Aberystwyth, in Ceredigion.
Motherboard has reported that a 13-foot-long cephalopod has been observed and captured this week alongside a boat's moorings in Toyama Bay, present along west coast of Japan. Filmed on December 24, observers identified the squid as the uncommon Architeuthis a species generally only discovered washed up on beaches or dead on the sea surface.
Architeuthis are known to dwell in the ocean depths, and their life span is generally for up to 5 years. They grow rapidly and reproduce only once during its lifetime. The species can measure up to 43 feet long, at its biggest.
A disease caused by a fungus called Ceratocystis fimbriata has killed hundreds of thousands of Hawaii’s iconic and native Ohia trees. Experts at the Department of Land and Natural Resources, (DLNR) Hawaii, said that Rapid Ohia Death (ROD) disease is new to Hawaii and it presently impacts just Big Island forests.
But, the DLNR has cautioned that the disease has the potential of spreading throughout the state.
NASA scientists are continuously receiving photos and data on Pluto that the New Horizons spacecraft captured during a flyby in July this year. A new set of images beamed back by the probe are some of the sharpest images we have ever seen of the dwarf planet.
NASA said the images with a resolution of about 250-280 feet per pixel exposing to Pluto’s view diverse surface. Cratered, mountainous and glacial terrains of the dwarf planet are clearly visible in new pictures.
Tesla Motors Inc. will likely roll out a self-driving or fully autonomous car within a couple of years, the electric-carmaker’s founder and CEO Elon Musk said.
In an interview given to Fortune, Mr. Musk said the company should have a fully autonomous car within next two years. However, he added that there are still many issues to be fixed and many factors to be considered.
Mr. Musk further added that he was confident that the supposed science fiction of fully autonomous cars could become a sustainable reality in near future.
On Friday, we lost a great psychiatrist who played a leading role in establishing agreed-upon standards to describe mental disorders and eliminating homosexuality's designation as pathology. Dr. Robert Spitzer, 83-year-old psychiatrist, died of heart problems in Seattle. Emerita Janet Williams, Columbia University Professor and wife of Dr. Robert Spitzer, said that there was a major breakthrough in the profession.
An exceptionally strong light-weight metal with high specific strength and modulus has been discovered by researchers from the UCLA Henry Samueli School of Engineering and Applied Science. They have come up with a new metal on infusing magnesium with dense silicon carbide nanoparticles. According to sources, the newly discovered metal could have significant implications in manufacturing of airplanes, cars, mobiles, electronics and many more. Researchers believe the newly discovered metal could help improve fuel efficiency as well as in biomedical devices.
Crows, some of the smartest birds, have long been known for their apparent propensity for using tools. But a new research paper published in the Biology Letters outlined a new video showing crows making tools in the wild.
The video, captured by cameras attached to New Caledonian crows, recorded tool-making by crows for the first time in the wild; rather than in captivity. It showed a crow creating a hooked tool that the birds use to catch bugs from narrow passages.
With the help of the radioactive dating technique, geologists at the University of Washington have found that the massive Rowan Landslide happened around 500 years ago. They analyzed the samples of wood buried in the Rowan landslide, just downstream of the Oso site, and the Headache Creek landslide, just upriver of the 2014 slide. With the help of new method to date all the previous landslides at a particular location, researchers found that the slopes in the area around Oso have collapsed on average once every 500 years.
