The measurement is higher than previous estimates, suggesting a different ecological niche for these youngsters.

Climate change is exacerbating problems like habitat loss and temperatures swings that have already pushed many animal species to the brink. But can scientists predict which animals will be able to adapt and survive? Using genome sequencing, researchers show that some fish, like the threespine stickleback, can adapt very rapidly to extreme seasonal changes. Their findings could help scientists forecast the evolutionary future of these populations.
The Antarctic ice sheet was even more unstable in the past than previously thought, and at times possibly came close to collapse, new research suggests. The findings raise concerns that, in a warmer climate, exposing the land underneath the ice sheet as it retreats will increase rainfall on Antarctica, and this could trigger processes that accelerate further ice loss.

Unlike humans, who map the world in units of distance, bats map the world in units of time. What this means is that the bat perceives an insect as being at a distance of nine milliseconds, and not one and a half meters, as was previously thought.
Scientists have found that lightning bolts and, surprisingly, subvisible discharges that cannot be seen by cameras or the naked eye produce extreme amounts of the hydroxyl radical and hydroperoxyl radical. The hydroxyl radical is important in the atmosphere because it initiates chemical reactions and breaks down molecules like the greenhouse gas methane.
A new study documents the newly named Bering Transitory Archipelago and then points to how, when and where the first Americans may have crossed. The authors' stepping-stones hypothesis depends on scores of islands that emerged during the last ice age as sea level fell when ocean waters were locked in glaciers and later rose when ice sheets melted.

Contrary to dogma that defensive venoms are simple in composition, mottled cup moth caterpillars (Doratifera vulnerans) produce a very complex venom containing 151 toxins spanning 59 families, most of which are peptides. Doratifera vulnerans is a common culprit of caterpillar envenomations in Australia. The binomial name of this species etymologically means ‘bearer of painful gifts.’
The banks of the artificial water reservoirs in Tikal, a major city of the ancient Maya world in what is now northern Guatemala, were primarily fringed with trees and wild vegetation, according to an analysis of ancient environmental DNA. “Almost all of Tikal’s city center was paved. That would get pretty hot during the dry
Paleontologists have performed a complete re-analysis of Oxyuropoda ligioides, a land-based peracarid crustacean first reported in 1908 from the Late Devonian floodplains of Ireland and left with unresolved systematic affinities despite a century of attempts at identification. “Woodlice and their relatives form a group of crustaceans named peracarids that are as species-rich as the more
Buff-tailed bumblebees (Bombus terrestris) are able to use differences in floral humidity to distinguish between rewarding and non-rewarding flowers, according to new research led by biologists from the University of Bristol and the University of Exeter. Floral humidity, a region of elevated humidity in the headspace of the flower, occurs in many plant species and
In a paper published this month in the journal Fungal Biology, a duo of paleontologists from the United States and France described a new genus and species of ancient parasitic fungus found in a piece of 50-million-year-old amber from Europe’s Baltic region. The newly-described species, named Allocordyceps baltica, is the oldest known fossil fungus of
About 66 million years ago, a 10-km- (6.2-mile) wide asteroid crashed into Earth near the site of the small town of Chicxulub in what is now Mexico. While this impact is firmly linked to the end-Cretaceous extinction of non-avian dinosaurs and 75% of life on the planet, the temporal relationship of the lesser-known Boltysh impact
Using data collected by the synthetic aperture radar on NASA’s Magellan spacecraft, a team of planetary researchers has identified a pattern of tectonic deformation on Venus that suggests that many of the planet’s lowlands have fragmented into discrete crustal blocks, and that these blocks have moved relative to each other in the geologically recent past. Despite
In a study involving almost 500,000 adults from the United Kingdom, a team of scientists from the University of Southampton and the University of Edinburgh Centre for Inflammation Research found that drinking coffee that is caffeinated (ground or instant) or decaffeinate was associated with a reduced risk of developing and dying from chronic liver disease
The end-Permian mass extinction — the most severe extinction event in the past 540 million years — was caused by massive volcanic eruptions in what is now Siberia, according to new research. “The end-Permian mass extinction, which occurred about 252 million years ago, was the most severe biotic crisis in the Phanerozoic Eon, eliminating more
The 110-million-year-old footprints discovered in Kent, southern England, were left by three types of dinosaurs, including theropod, ornithopod, and ankylosaur dinosaurs. The 110-million-year-old (Early Cretaceous epoch) dinosaur footprints were discovered in the cliffs and on the foreshore in Folkestone, where stormy conditions affect the cliff and coastal waters, and are constantly revealing new fossils. “This
Astrophysical observations show that supermassive black holes exist when the Universe is just 800 million years old after the Big Bang (just 6% of its current age). The origin of these compact objects is still a mystery; in particular, it is extremely puzzling how they could become so massive in such a cosmologically short time
A team of researchers from the University of California, San Diego, the Universidad Nacional de La Plata and the Kavli Institute for Brain and Mind has demonstrated a vocal synthesizer for birdsong, realized by mapping brain activity recorded from electrode arrays implanted into bird brain tissue. The team was able to reproduce the complex vocalizations
Astronomers using the NASA/ESA Hubble Space Telescope have captured an amazing new photo of the interacting galaxy system IC 1623. IC 1623 is located some 274 million light-years away in the constellation of Cetus. Also known as Arp 236, ESO 541-23 and IRAS 01053-1746, the galaxy pair was discovered on November 19, 1897 by the
In a new study published in the journal Geoscience Frontiers, a team of U.S. researchers analyzed the ages of 89 well-dated geological events of the last 260 million years — such as marine and non-marine extinctions, major ocean-anoxic events, sea-level fluctuations — from the recent geologic literature. “Many geologists believe that geological events are random
A new species of the giant rhinoceros genus Paraceratherium has been identified from the fossilized remains found in Gansu Province, northwestern China. The newly-identified rhino species lived during the Oligocene epoch, around 26.5 million years ago. Named Paraceratherium linxiaense, it belongs to Paraceratherium, a small genus of extinct hornless rhinos. “The giant rhino has been
African coelacanths (Latimeria chalumnae) reach maturity around the age of 55 and gestate their offspring for 5 years, according to a study published in the journal Current Biology. Coelacanths are large lobe-finned fish (sarcopterygians) that were thought to be extinct for 65 million years, until a first living specimen was caught fortuitously in South Africa
In a new study, astronomers used data from the NASA/ESA Hubble Space Telescope to calculate a more accurate distance to an ultra-diffuse galaxy called NGC 1052-DF2 (DF2 for short). The new measurement solidifies previous claims that DF2 lacks dark matter, the invisible glue that makes up the bulk of the Universe’s contents. DF2 lies in
The sweat bee Megalopta genalis, a Neotropical nocturnal bee species that navigates under the forest canopy at light intensities 10 times dimmer than starlight, is able to learn dorsal landmarks to find its nest during homing, the first flying insect known with this capacity. Megalopta genalis is a species in the family Halictidae (commonly referred
Betelgeuse, which is located roughly 724 light-years away in the constellation of Orion, is the second-closest red supergiant to Earth. From November 2019 to March 2020, this star experienced a historic dimming of its visible brightness. Usually having an apparent magnitude between 0.1 and 1, its visual brightness decreased to 1.6 magnitudes around 7-13 February
