Scientists discover deepest known evidence of coral reef bleaching      (via sciencedaily.com)     Original source 

Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.

New mollusk and crustacean species in symbiosis with worms in dead coral rocks      (via sciencedaily.com)     Original source 

The symbiotic communities of invertebrates in dead coral gravel on the shallow, warm-temperate coast of the Kii Peninsula in western Japan. New bivalve species and sideswimmer have been found to live communally with the greenish Bonellia spoonworm. Live-in symbionts share the burrows of other organisms in sand and mud on the seabed. However, studies on burrow niches in rigid substrates, such as rocks on the seabed, have been scarce.

Source of largest ever Mars quake revealed      (via sciencedaily.com)     Original source 

Scientists have announced the results of an unprecedented collaboration to search for the source of the largest ever seismic event recorded on Mars. The study rules out a meteorite impact, suggesting instead that the quake was the result of enormous tectonic forces within Mars' crust.

Signatures of the Space Age: Spacecraft metals left in the wake of humanity's path to the stars      (via sciencedaily.com)     Original source 

Using tools hitched to the nose cone of their research planes and sampling more than 11 miles above the planet's surface, researchers have discovered significant amounts of metals in aerosols in the atmosphere, likely from increasingly frequent launches and returns of spacecraft and satellites. That mass of metal is changing atmospheric chemistry in ways that may impact Earth's atmosphere and ozone layer.

Climate change coping mechanism discovered in humble algae      (via sciencedaily.com)     Original source 

One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops.

Wildfires threaten environmental gains in climate-crucial Amazon      (via sciencedaily.com)     Original source 

Despite steps toward decreasing deforestation, uncontrolled wildfires are threatening environmental gains in Brazilian Amazonia, one of the world's most critical carbon sinks and a region of high biological and cultural diversity.

Researchers capture first-ever afterglow of huge planetary collision in outer space      (via sciencedaily.com)     Original source 

A chance social media post by an eagle-eyed amateur astronomer sparked the discovery of an explosive collision between two giant planets, which crashed into each other in a distant space system 1,800 light years away from planet Earth.

'Starquakes' could explain mystery signals      (via sciencedaily.com)     Original source 

Fast radio bursts, or FRBs, are an astronomical mystery, with their exact cause and origins still unconfirmed. These intense bursts of radio energy are invisible to the human eye, but show up brightly on radio telescopes. Previous studies have noted broad similarities between the energy distribution of repeat FRBs, and that of earthquakes and solar flares. However, new research has looked at the time and energy of FRBs and found distinct differences between FRBs and solar flares, but several notable similarities between FRBs and earthquakes. This supports the theory that FRBs are caused by 'starquakes' on the surface of neutron stars. This discovery could help us better understand earthquakes, the behavior of high-density matter and aspects of nuclear physics.

Source of electron acceleration and X-ray aurora of Mercury local chorus waves detected      (via sciencedaily.com)     Original source 

Observations during two flybys by the Mio spacecraft as part of the BepiColombo International Mercury Exploration Project have revealed that chorus waves occur quite locally in the dawn sector of Mercury. Mercury's magnetic field is about 1% of that of Earth, and it was unclear whether chorus waves would be generated like on Earth. The present study reveals that the chorus waves are the driving source of Mercury's X-ray auroras, whose mechanism was not understood.

Astronomers discover first step toward planet formation      (via sciencedaily.com)     Original source 

Astronomers have gotten very good at spotting the signs of planet formation around stars. But for a complete understanding of planet formation, we also need to study examples where planet formation has not yet started. Looking for something and not finding it can be even more difficult than finding it sometimes, but new detailed observations of the young star DG Taurus show that it has a smooth protoplanetary disk without signs of planet formation. This successful non-detection of planet formation may indicate that DG Taurus is on the eve of planet formation.

Scientists discover the highest energy gamma-rays ever from a pulsar      (via sciencedaily.com)     Original source 

Scientists have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy of visible light. This observation is hard to reconcile with the theory of the production of such pulsed gamma rays, as the international team reports.

Plot thickens in hunt for ninth planet      (via sciencedaily.com)     Original source 

A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity originally developed to understand the rotation of galaxies.

A prehistoric cosmic airburst preceded the advent of agriculture in the Levant      (via sciencedaily.com)     Original source 

Agriculture in Syria started with a bang 12,800 years ago as a fragmented comet slammed into the Earth’s atmosphere. The explosion and subsequent environmental changes forced hunter-gatherers in the prehistoric settlement of Abu Hureyra to adopt agricultural practices to boost their chances for survival.

Carbon-capture tree plantations threaten tropical biodiversity for little gain, ecologists say      (via sciencedaily.com)     Original source 

The increasingly urgent climate crisis has led to a boom in commercial tree plantations in an attempt to offset excess carbon emissions. However, authors argue that these carbon-offset plantations might come with costs for biodiversity and other ecosystem functions. Instead, the authors say we should prioritize conserving and restoring intact ecosystems.

Large mound structures on Kuiper belt object Arrokoth may have common origin      (via sciencedaily.com)     Original source 

A new study posits that the large, approximately 5-kilometer-long mounds that dominate the appearance of the larger lobe of the pristine Kuiper Belt object Arrokoth are similar enough to suggest a common origin. The study suggests that these “building blocks” could guide further work on planetesimal formational models.
