New models explain canyons on Pluto moon

Science Daily - 08/02/2023
In 2015, when NASA's New Horizons spacecraft encountered the Pluto-Charon system, scientists discovered interesting, geologically active objects instead of the inert icy orbs previously envisioned. Scientists have revisited the data to explore the source of cryovolcanic flows and an obvious belt of fractures on Pluto's large moon Charon. These new models suggest that when the moon's internal ocean froze, it may have formed the deep, elongated depressions along its girth but was less likely to lead to cryovolcanoes erupting with ice, water and other materials in its northern hemisphere.

Antarctica's ocean brightens clouds

Science Daily - 08/02/2023
The teeming life in the Southern Ocean, which encircles Antarctica, contributes to brightening the clouds that form there, according to a new study. The clouds are bright because of their high density of water droplets, due in turn to a chain of atmospheric processes that eventually connects back to the Southern Ocean's extraordinary phytoplankton productivity.

Model devised to understand global warming impact on weathering, Earth's thermostat: Study

Rocks, rain and carbon dioxide help control Earth's climate over thousands of years - like a thermostat - through a process called weathering.

Fertility treatment does not adversely affect cardiovascular health of offspring, international study suggests

A large study looking at the effects of fertility treatment has found no robust difference in blood pressure, heart rate, lipids, and glucose measurements between children conceived naturally and those conceived using assisted reproductive technologies (ART).

Copy-cat? Youth with few friends conform to stay in a friend's 'good graces'

Science Daily - 07/02/2023
What gives one friend influence over another? Considerable attention has focused on who influences whom; much less is known about why one partner is prone to be influenced by the other. A study tested the hypothesis that within a friend dyad, having fewer friends than one's partner increases susceptibility to influence, because it reduces dissimilarity and promotes compatibility. Results showed that partners with fewer friends were influenced by children with more friends. In each case, the partner with fewer friends became more similar to the partner with more friends. Academic engagement was the only domain where partners with fewer friends also influenced partners with more friends.

Plastic debris in the Arctic comes from all around the world

Science Daily - 07/02/2023
In the course of five years, citizens who went on sailing cruises to the Arctic surveyed and collected plastic debris that had washed up on the shores of Svalbard. This has now been analyzed. According to the findings, one third of the plastic debris which still bore imprints or labels allowing an analysis of their origin came from Europe, and much of that number from Germany.

Fungi and bacteria are binging on burned soil

Young blood may be an elixir for older bodies, rejuvenating aging hearts, muscles, and brains. But how can old blood become young again? Stem cell scientists may have found a way.

Long-term restoration of a biodiversity hotspot hinges on getting seeds to the right place at the right time

Science Daily - 07/02/2023
New research shows that degraded savanna ecosystems can reap lasting benefits from a single seeding of native understory plants. Once a diverse understory of savanna plants became established, its long-term persistence was relatively unaffected by environmental factors -- with one exception. Higher temperatures during the height of the growing season were associated with poorer long-term survival among some species, indicating one threat posed by a warming climate.

Loss of reptiles poses threat for small islands where humans may have caused extinctions

Science Daily - 07/02/2023
A new examination of ancient and current species of reptiles conducted by paleobiologists reveals the serious impact of the disappearance of even a few species of reptiles in some island areas. The study has startling conclusions about how, on smaller islands in the Caribbean where human impact was greatest, extinctions have led to the loss of up to two-thirds of the supports for the ecosystem that native reptile species once provided there.
