A new study shows that suppressing a protein turns ordinary fat into a calorie burner and may explain why drug trials attempting the feat haven’t been successful.

Researchers at UC San Francisco have figured out how to turn ordinary white fat cells, which store calories, into beige fat cells that burn calories to maintain body temperature.

The discovery could open the door to developing a new class of weight-loss drugs and may explain why clinical trials of related therapies have not been successful.

A US Senate investigation is shedding light on just how often America’s big banks refuse to reimburse victims of fraud.

The Permanent Subcommittee on Investigations says JPMorgan Chase, Wells Fargo and Bank of America collectively refused to reimburse $880 million in Zelle transactions that customers reported as fraud between 2021 and 2023.

Specifically, the banks refused to reimburse $320 million to customers who were hit by unauthorized transactions – and rejected an additional $560 million in reimbursement to customers who were tricked into authorizing an illicit transaction.

Astronomers have uncovered the secrets behind an epic collision of two massive galaxy clusters, showing that dark matter and regular matter can actually separate during these huge events.

Located billions of light-years away, these clusters are home to thousands of galaxies and provide deep insights into the complexities of our universe.

When they collided, the dark matter — an invisible substance affected by gravity but not light — moved ahead of the normal matter, which includes gas and stars.

NASA’s Fermi Telescope has revealed new details about the brightest of all time gamma-ray burst which may help explain these extreme and mysterious cosmic events.

Gamma-ray bursts (GRBs) usually last less than a second. They originate from the dense remains of a dead giant star’s core, called a neutron star. But what causes neutron stars to release huge amounts of energy in the form of gamma radiation is still a mystery.

In October 2022, astronomers detected the largest gamma-ray burst ever seen – GRB 221009A. It came from a supernova about 2.4 billion light years away. The event had an intensity at least 10 times greater than any other GRB detected. It was dubbed the BOAT, for brightest of all time.

Grasping the precise energy landscapes of quantum particles can significantly enhance the accuracy of computer simulations for material sciences. These simulations are instrumental in developing advanced materials for applications in physics, chemistry, and sustainable technologies. The research tackles longstanding questions from the 1980s, paving the way for breakthroughs across various scientific disciplines.

An international group of physicists, led by researchers at Trinity College Dublin, has developed new theorems in quantum mechanics that explain the “energy landscapes” of quantum particle collections. Their work resolves decades-old questions, paving the way for more accurate computer simulations of materials. This advancement could significantly aid scientists in designing materials poised to revolutionize green technologies.

The new theorems have just been published in the prominent journal Physical Review Letters. The results describe how the energy of systems of particles (such as atoms, molecules, and more exotic matter) changes when their magnetism and particle count change. Solving an open problem important to the simulation of matter using computers, this extends a series of landmark works commencing from the early 1980s.
