The inner workings of black holes are more complex than previously thought.
New research suggests black holes are unstable, challenging Einstein’s theory of general relativity and the Kerr solution.
A US bank is warning customers of a security “intrusion” that may have compromised Mastercard account numbers and other financial data.
Maryland-based Eagle Bank says it has received a notice from Mastercard, stating an unnamed US merchant allowed unauthorized access to account information between August 15th, 2023, and May 25th, 2024.
The bank revealed the breach in a filing with the Massachusetts state government.
A study introduces AI2BMD, an artificial intelligence-based dynamics simulation program that uses protein fragmentation with a machine learning force field to accurately and efficiently model the folding and unfolding of large proteins.
Scientists claim that experimental studies of Higgs boson interactions face a fundamental challenge.
Scientists believe that interactions between Higgs bosons could unlock insights into new physics. Discovered at CERN’s Large Hadron Collider (LHC) in 2012, the elusive Higgs boson particle has been at the centre stage for exploring new possibilities in particle physics.
Scientists claimed that the production of Higgs boson pairs can occur within the Standard Model itself. It is such a rare process here that it has not been possible to observe it in the data collected so far.
A small asteroid burned up in Earth’s atmosphere off the coast of California just hours after being discovered and before impact monitoring systems had registered its trajectory.
Rapid advances in applying artificial intelligence to simulations in physics and chemistry have some people questioning whether we will even need quantum computers at all.

Researchers at Paul Scherrer Institute (PSI), using muon spin rotation at the Swiss Muon Source (SmS), have discovered that a quantum phenomenon called time-reversal symmetry breaking takes place at the surface of the Kagome superconductor RbV₃Sb₅, occurring at temperatures up to 175 K.
This sets a new record for the temperature at which time-reversal symmetry breaking is observed among Kagome systems.
Deep sleep could be key to forestalling slow declines in brain health that may one day lead to Alzheimer’s disease, the most common form of dementia.
In their 2023 study of 62 older, cognitively healthy adults, researchers from the University of California (UC) Berkeley, Stanford University, and UC Irvine in the US found individuals with brain changes associated with Alzheimer’s performed better on memory function tests as they got more deep sleep.
This was irrespective of education and physical activity, two factors along with social connection known to contribute to cognitive resilience in older age.
“The first involved integrating the hole-selective materials and the perovskite layers, to simplify the manufacturing process. The second involved replacing traditional organic materials, such as fullerene and bathocuproine, with tin oxide, an inorganic electron transport layer, in a process known as the atomic layer deposition method,” per PV’s description.
Labspeak aside, the big takeaway is that the changes resulted in a 25% efficiency, meaning the cells can turn a quarter of the sunlight hitting them into energy. What’s more, they maintained 95% of their efficiency after 2,000 hours of operation, per the report.
