New research from the University of St Andrews has proposed that particles in solar flares are 6.5 times hotter than previously thought. The research provides an unexpected solution to a 50-year-old mystery about our nearest star.

Solar flares are sudden and huge releases of energy in the sun's outer atmosphere that heat parts of it to greater than 10 million degrees. These dramatic events greatly increase the solar X-rays and radiation reaching Earth and are hazardous to spacecraft and astronauts, as well as affecting our planet's upper atmosphere.

The research, published in The Astrophysical Journal Letters, looks at evidence of how flares heat solar plasma to greater than 10 million degrees. This solar plasma is made up of ions and electrons. The new research argues that solar flare ions, positively charged particles that make up half of the plasma, can reach over 60 million degrees.

In a groundbreaking achievement, researchers at the CRCHUM, the hospital research center affiliated with Université de Montréal, have identified a type of microRNA that can safeguard small blood vessels and help maintain kidney function following severe injury.

This discovery holds significant promise for the more than four million Canadians living with chronic renal failure, as well as millions of patients worldwide, by offering new possibilities for earlier detection and prevention of the disease.

Until now, there had been no dependable biomarker to assess the condition of these delicate capillaries or to guide targeted strategies aimed at protecting kidney function.

For decades, scientists have wrestled with a simple question: what happened to the Moon’s magnetism? Instruments on orbiting spacecraft once detected strong magnetic signatures in lunar surface rocks, indicating a powerful field in the past. Yet the moon itself has no inherent magnetism today.

Researchers at MIT now believe they may have uncovered the answer. Their hypothesis suggests that the Moon once possessed a faint magnetic field, and when a massive impact occurred, it produced a burst of plasma that temporarily strengthened this field, particularly on the far side of the Moon.

New research investigates the possibility that different spacecraft could visit Comet 3I/ATLAS, giving scientists a unique on-location view of the interstellar visitor, or even offering the chance to collect material that could be much older than the bodies of our solar system.

After up to 45 days in their father’s brood pouch, baby seahorses—each around the size of a jelly bean—float together in small groups, wrapping their tails around one another as they travel.

Just 500 million years after the Big Bang, a colossal black hole, 300 million times the mass of the Sun, was already blazing at the heart of a tiny, brilliant galaxy. Found with JWST, this discovery could explain the strange "Little Red Dots" seen in the early cosmos and rewrites what we thought was possible for black hole growth.

Scientists have developed a more efficient way to generate oxygen for astronauts that could help with future missions into deep space.

Current life-support systems such as those on the International Space Station (ISS) rely on bulky centrifuges to separate the oxygen and hydrogen bubbles created when water is split by electricity, a process known as electrolysis. On Earth, bubbles rise away from electrodes, but in microgravity, spinning is required to separate them. This method works, but the equipment is heavy, power-hungry and is ill-suited for long-duration missions to the moon or Mars.

A new study led by Alvaro Romero-Calvo of the Georgia Institute of Technology, in collaboration with colleagues at the University of Bremen’s Center of Applied Space Technology and Microgravity (ZARM) and the University of Warwick, has demonstrated a simpler, lighter and more sustainable solution in the form of magnets.

Plastics that support modern life are inexpensive, strong, and versatile, but are difficult to dispose of and have a serious impact when released into the environment. Polyethylene, in particular, is the most widely produced plastic in the world, with more than 100 million tons distributed annually. Since it can take decades to decompose—and along the way can harm wildlife and degrade into harmful microplastics—its disposal is an urgent issue for mankind.

In 2017, European researchers discovered a potential solution. The larvae of wax moths, commonly known as wax worms, have the ability to break down polyethylene in their bodies. Wax worms have been considered a pest since ancient times because they parasitize beehives, feeding on beeswax. However, we now know that they also spontaneously feed on polyethylene, which has a chemically similar structure.
