Ancient genome analyses reveal mosaic pattern of goat domestication thousands of years ago
Ancient genome analyses reveal mosaic pattern of goat domestication thousands of years ago

An international team of scientists, led by geneticists from Trinity College Dublin, have sequenced the genomes from ancient goat bones from areas in the Fertile Crescent where goats were first domesticated around 8,500 BC. They reveal a 10,000-year history of local farmer practices featuring genetic exchange both with the wild and among domesticated herds, and ...

Oxygen loss in the coastal Baltic Sea is ‘unprecedentedly severe’
Oxygen loss in the coastal baltic sea is unprecedentedly severe

The Baltic Sea is home to some of the world’s largest dead zones, areas of oxygen-starved waters where most marine animals can’t survive. But while parts of this sea have long suffered from low oxygen levels, a new study by a team in Finland and Germany shows that oxygen loss in coastal areas over the ...

I am human, hear me roar: Judging formidability from human vocalizations
I am human hear me roar judging formidability from human vocalizations

Many animals — including sea lions, red deer, and dogs — use vocalizations to judge one another’s size and physical formidability when in competition for mates or other resources. Now, researchers reporting in the journal iScience on June 28 have found that humans can use nonverbal vocal cues, including aggressive roars, in a similar way. ...

Physicists set limits on size of neutron stars
Physicists set limits on size of neutron stars

How large is a neutron star? Previous estimates varied from eight to 16 kilometres. Astrophysicists at the Goethe University Frankfurt and the FIAS have now succeeded in determining the size of neutron stars to within 1.5 kilometres by using an elaborate statistical approach supported by data from the measurement of gravitational waves. The researchers’ report ...

Biologists show that female seals have consistent personalities
Biologists show that female seals have consistent personalities

Female seals don’t change their spots, according to a new study by University of Alberta biologists. In fact, individual differences in boldness remain consistent over time. The study is among the first to examine boldness in wild marine mammals in the burgeoning field of animal personality. Animal personality influences many ecological processes, like how individuals ...

Researchers capture best ever evidence of rare black hole
Researchers capture best ever evidence of rare black hole

ESA’s XMM-Newton observatory has discovered the best-ever candidate for a very rare and elusive type of cosmic phenomenon: a medium-weight black hole in the process of tearing apart and feasting on a nearby star. There are various types of black hole lurking throughout the Universe: massive stars create stellar-mass black holes when they die, while ...

‘Stealth sheet’ hides hot objects from prying infrared eyes
Stealth sheet hides hot objects from prying infrared eyes

Infrared cameras are the heat-sensing eyes that help drones find their targets, even in the dead of night or through heavy fog. Hiding from such detectors could become much easier, thanks to a new cloaking material that renders objects—and people—practically invisible. “What we have shown is an ultrathin stealth ‘sheet.’ Right now, what people have ...

New mechanism for the plant hormone auxin discovered
New mechanism for the plant hormone auxin discovered

Auxin is a hormone that is essential for the development of plants as it controls a wide range of processes from shaping the embryo in the seed to branching of the growing plant. Previously, it was believed that auxin’s main signaling mechanism operated in the cell nucleus and acted only by regulating gene transcription. Now, ...

Microbe breaks ‘universal’ DNA rule by using two different translations
Microbe breaks universal dna rule by using two different translations

DNA is often referred to as the blueprint for life, however scientists have for the first time discovered a microbe that uses two different translations of the DNA code at random. This unexpected finding breaks what was thought to be a universal rule, since the proteins from this microbe cannot be fully predicted from the ...

AI recreates chemistry’s periodic table of elements
Ai recreates chemistrys periodic table of elements

It took nearly a century of trial and error for human scientists to organize the periodic table of elements, arguably one of the greatest scientific achievements in chemistry, into its current form. A new artificial intelligence (AI) program developed by Stanford physicists accomplished the same feat in just a few hours. Called Atom2Vec, the program ...
