A new type of Homo unknown to science

Posted: 24 Jun 2021 11:15 AM PDT

The bones of an early human, unknown to science, who lived in the Levant at least until 130,000 years ago, were discovered in excavations at the Nesher Ramla site, near the city of Ramla. Recognizing similarity to other archaic Homo specimens from 400,000 years ago, found in Israel and Eurasia, the researchers reached the conclusion that the Nesher Ramla fossils represent a unique Middle Pleistocene population, now identified for the first time.

Comet strike may have sparked key shift in human civilization

A cluster of comet fragments believed to have hit Earth nearly 13,000 years ago may have shaped the origins of human civilization, research suggests.

Research team discovers Arctic dinosaur nursery

Posted: 24 Jun 2021 08:44 AM PDT

Images of dinosaurs as cold-blooded creatures needing tropical temperatures could be a relic of the past. Scientists have found that nearly all types of Arctic dinosaurs, from small bird-like animals to giant tyrannosaurs, reproduced in the region and likely remained there year-round.

Water vole genome will help boost conservation of one of UK's most endangered mammals

A new tool to help conserve one of the UK's most threatened mammals has been released today, with the publication of the first high-quality reference genome for the European water vole.

Antarctic Circumpolar Current flows more rapidly in warm phases

Posted: 24 Jun 2021 08:44 AM PDT

Our planet's strongest ocean current, which circulates around Antarctica, plays a major role in determining the transport of heat, salt and nutrients in the ocean. An international research team led by the Alfred Wegener Institute has now evaluated sediment samples from the Drake Passage.

New knowledge of Earth's mantle helps to explain Indonesia's explosive volcanoes

Posted: 24 Jun 2021 08:44 AM PDT

Indonesia's volcanoes are among the world's most dangerous. Why? Through chemical analyses of tiny minerals in lava from Bali and Java, researchers have found new clues. They now understand better how the Earth's mantle is composed in that particular region and how the magma changes before an eruption.

Newly sequenced genome of extinct giant lemur sheds light on animal's biology

Posted: 24 Jun 2021 08:43 AM PDT

Using an unusually well-preserved subfossil jawbone, a team of researchers has sequenced for the first time the nuclear genome of the koala lemur (Megaladapis edwardsi), one of the largest of the 17 or so giant lemur species that went extinct on the island of Madagascar between about 500 and 2,000 years ago.

Being Anglo-Saxon was a matter of language and culture, not genetics

Posted: 23 Jun 2021 11:49 AM PDT

Archaeologists have provided important new evidence to answer the question 'who exactly were the Anglo-Saxons?' New findings based on studying skeletal remains clearly indicates the Anglo-Saxons were a melting pot of people from both migrant and local cultural groups and not one homogenous group from Western Europe.

3,000-year-old shark attack victim

Researchers reveal their discovery of a 3,000-year-old victim - attacked by a shark in the Seto Inland Sea of the Japanese archipelago.

New research reveals remarkable resilience of sea life in the aftermath of mass extinctions

Posted: 23 Jun 2021 08:39 AM PDT

Pioneering research has shown marine ecosystems can start working again, providing important functions for humans, after being wiped out much sooner than their return to peak biodiversity.

Pleistocene sediment DNA from Denisova Cave

Posted: 23 Jun 2021 08:38 AM PDT

Researchers have analyzed DNA from 728 sediment samples from Denisova Cave. Their study provides unprecedented detail about the occupation of the site by both archaic and modern humans over 300,000 years. The researchers detected the DNA of Neandertals and Denisovans, the two forms of archaic hominins who inhabited the cave, and the DNA of modern humans who appeared around the time of the emergence of an archaeological culture called the Initial Upper Paleolithic around 45,000 years ago.

Earth-like biospheres on other planets may be rare

Posted: 23 Jun 2021 08:38 AM PDT

A new analysis of known exoplanets has revealed that Earth-like conditions on potentially habitable planets may be much rarer than previously thought. The work focuses on the conditions required for oxygen-based photosynthesis to develop on a planet, which would enable complex biospheres of the type found on Earth.

The origins of farming insects more than 100 million years ago

Posted: 23 Jun 2021 08:38 AM PDT

A beetle bores a tree trunk to build a gallery in the wood in order to protect its lay. As it digs the tunnel, it spreads ambrosia fungal spores that will feed the larvae. When these bore another tree, the adult beetles will be the transmission vectors of the fungal spores in another habitat. This mutualism among insects and ambrosia fungi could be more than 100 million years old, more than what was thought to date.

Tuckered out: Early Antarctic explorers underfed their dogs

New research analyzing a century-old dog biscuit suggests early British Antarctic expeditions underfed their dogs.
