A power company that has received £6bn in UK green subsidies has kept burning wood from some of the world's most precious forests, the BBC has found.

Papers obtained by Panorama show Drax took timber from rare forests in Canada it had claimed were "no go areas".

It comes as the government decides whether to give the firm's Yorkshire site billions more in environmental subsidies funded by energy bill payers.

When a star like our sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it. Now, using the European Southern Observatory's Very Large Telescope (ESO's VLT) in Chile, researchers have found a unique signature of this process for the first time—a scar imprinted on the surface of a white dwarf star. The results are published in The Astrophysical Journal Letters.

"It is well known that some white dwarfs—slowly cooling embers of stars like our sun—are cannibalizing pieces of their planetary systems. Now we have discovered that the star's magnetic field plays a key role in this process, resulting in a scar on the white dwarf's surface," says Stefano Bagnulo, an astronomer at Armagh Observatory and Planetarium in Northern Ireland, UK, and lead author of the study.

Striped marlin are some of the fastest animals on the planet and one of the ocean's top predators. When hunting in groups, individual marlin will take turns attacking schools of prey fish one at a time. Now a new study reported in the journal Current Biology helps to explain how they might coordinate this turn-taking style of attack on their prey to avoid injuring each other. The key, according to the new work, is rapid color changes.

"We documented for the first time rapid color change in a group-hunting predator, the striped marlin, as groups of marlin hunted schools of sardines," says Alicia Burns of Humboldt University in Berlin, Germany. "We found that the attacking marlin 'lit up' and became much brighter than its groupmates as it made its attack before rapidly returning to its 'non-bright' coloration after its attack ended."

The 1963 Civil Rights victory in Birmingham, Alabama paved the way for the 1964 Civil Rights Act. In their latest article, published in Humanities and Social Sciences Communications, UMass Amherst Associate Professor of History Kevin Young and Yale University environmental social scientist Laura Thomas-Walters ask: What are the lessons from that monumental victory for today's climate movement?

"We wanted to think more deeply about the concept of disruption with an eye toward being useful to the climate movement," Young says. "Lessons from 1963 are often misunderstood."

A comet is set to pass by Earth this spring, and it may be missing its tail.

The comet poses no danger to Earth—it is about the same distance from our planet as we are from the sun—but scientists need images of C/2021 S3 Pannstars from amateur astronomers to improve forecasts of space weather. These forecasts are vital to prevent problems caused by solar winds, which are streams of particles containing solar storms that can damage technology in space and on Earth.

Sarah Watson, the University of Reading Ph.D. researcher leading the project, said, "What we are expecting to see may look rather unusual. When we talk about comets, people often think of a large, bright sphere followed by a long thin tail."

"The comet we are observing may look different as its tail could 'detach' as it is buffeted by solar winds."

"We need lots of timed photos of the comet to build up a picture of its journey through our solar system. This is a fantastic opportunity for amateur astronomers to get out their telescopes, capture a truly spectacular cosmic moment, and make a big contribution to some important science."

A few years ago, astronomers uncovered one of the Milky Way's greatest secrets: An enormous, wave-shaped chain of gaseous clouds in our sun's backyard, giving birth to clusters of stars along the spiral arm of the galaxy we call home.

Naming this astonishing new structure the Radcliffe Wave, in honor of the Harvard Radcliffe Institute, where the undulation was originally discovered, the team now reports in Nature that the Radcliffe Wave not only looks like a wave, but also moves like one—oscillating through space-time much like "the wave" moving through a stadium full of fans.

UK ministers are facing court for a second time over plans to meet legally binding climate targets, after environmental groups branded revised measures “a complete pipe dream”.

The government has already been forced to change its climate action plan after a legal challenge by environmentalists, but the same groups are taking it back to court over updated plans they say are “riddled with holes and relian[t] on risky techno-fixes”.

“We believe the government’s revised climate action plan is a complete pipe dream,” said Katie de Kauwe, a lawyer for Friends of the Earth. “It lacks critical information on the very real risks that its policies will fail to deliver the cuts needed to meet legally binding carbon reduction targets and relies too heavily on unproven technologies.
