Great apes like teasing each other - which may be the origin of humour

New Scientist - Tue, 02/13/2024 - 18:01
Chimpanzees, bonobos, orangutans and gorillas frequently toy with their peers by poking, tickling or stealing from them, perhaps showing behaviours that were prerequisites for human joking

Small dogs are more likely to have an extra row of teeth like sharks

New Scientist - Tue, 02/13/2024 - 08:00
Some pet dogs retain their baby teeth, creating two rows that resemble the mouth of a shark. A new analysis shows that the condition is more prevalent in smaller breeds and obese dogs

Researchers studying ocean transform faults, describe a previously unknown part of the geological carbon cycle

Science Daily - Paleontology - Mon, 02/12/2024 - 14:35
This study reports widespread mineral carbonation of mantle rocks in an oceanic transform fueled by magmatic degassing of CO2. The findings describe a previously unknown part of the geological carbon cycle in transform faults that represent one of the three principal plate boundaries on Earth. The confluence of tectonically exhumed mantle rocks and CO2-rich alkaline basalt formed through limited extents of melting characteristic of the St. Paul's transform faults may be a pervasive feature at oceanic transform faults in general. Because transform faults have not been accounted for in previous estimates of global geological CO2 fluxes, the mass transfer of magmatic CO2 to the altered oceanic mantle and seawater may be larger than previously thought.

The hidden rule for flight feathers -- and how it could reveal which dinosaurs could fly

Science Daily - Paleontology - Mon, 02/12/2024 - 14:33
Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.

Surprisingly vibrant color of 12-million-year-old snail shells

Science Daily - Paleontology - Fri, 02/09/2024 - 15:34
Snail shells are often colorful and strikingly patterned. This is due to pigments that are produced in special cells of the snail and stored in the shell in varying concentrations. Fossil shells, on the other hand, are usually pale and inconspicuous because the pigments are very sensitive and have already decomposed. Residues of ancient color patterns are therefore very rare. This makes a new discovery all the more astonishing: researchers found pigments in twelve-million-year-old fossilized snail shells.

New fossil site of worldwide importance uncovered in southern France

Science Daily - Paleontology - Fri, 02/09/2024 - 12:41
Nearly 400 exceptionally well-preserved fossils dating back 470 million years have been discovered in the south of France by two amateur paleontologists. The discovery provides unprecedented information on the polar ecosystems of the Ordovician period.

Ancient pollen trapped in Greenland ice uncovers changes in Canadian forests over 800 years

Science Daily - Paleontology - Thu, 02/08/2024 - 13:24
The Greenland ice sheet lies thousands of miles from North America yet holds clues to the distant continent's environmental history. Nearly two miles thick in places, the ice sheet grows as snow drifts from the sky and builds up over time. But snow isn't the only thing carried in by air currents that swirl around the atmosphere, with microscopic pollen grains and pieces of ash mixing with snowfall and preserving records of the past in the ice. A new study examined these pollen grains and identified how eastern Canada's forests grew, retreated, and changed through time.

What turned Earth into a giant snowball 700 million years ago? Scientists now have an answer

Science Daily - Paleontology - Wed, 02/07/2024 - 18:44
Inspired during field work in South Australia's Flinders Ranges, geoscientists have proposed that all-time low volcanic carbon dioxide emissions triggered a 57-million-year-long global 'Sturtian' ice age.
