Mass General Brigham researchers find too much sitting hurts the heart

A new study by Mass General Brigham researchers found that excessive sedentary behavior increases the risk of heart failure and cardiovascular death. Even among individuals who meet guideline levels of moderate-to-vigorous physical activity, sitting for extended periods can still pose significant health risks. The study's findings sugg...

The heaviest element ever chemically studied — Experiments at GSI/FAIR succeed in determining properties of moscovium and nihonium

Researchers have determined the chemical properties of moscovium and nihonium, which are more reactive than flerovium. The study uses a newly developed setup for chemical separation and detection to observe the very short-lived moscovium-288 and its daughter nihonium-284.

Like humans, artificial minds can learn by thinking

A recent review suggests that artificial intelligence can learn by thinking, similar to humans, through processes such as explanation, simulation, analogy, and reasoning. This finding has implications for understanding the similarities and differences between human and artificial cognition, and could lead to improvements in AI systems.

Generative AI model study shows no racial or sex differences in opioid recommendations for treating pain

A new study from Mass General Brigham researchers found that large language models demonstrated no racial or gender discrimination in opioid treatment recommendations. The results suggest that these AI models have the potential to reduce bias and improve health equity in pain management, which is a critical area where disparities exist.

Children living in deprived areas are three times more likely to need dental extractions in hospital

A study published in BMJ Public Health found that children living in deprived areas have a three times higher risk of needing dental extractions under general anaesthesia. This highlights the need for targeted interventions and improved access to preventive dental services to address socioeconomic and ethnic inequalities in oral health.

What happens when neutron stars collide?

New simulations show that neutrinos created during neutron star collisions can be trapped at the interface of merging stars and interact with matter for 2-3 milliseconds. This brief out-of-equilibrium phase is crucial in understanding the physics of these extreme events.

Assessment of knowledge of general and local anesthesia among patients undergoing elective surgery

A study of 370 patients undergoing elective surgery found that those with higher levels of awareness about anesthesia had better understanding of general and local anesthesia. Patients who underwent surgeries related to eyes, nose, and throat scored higher on the knowledge test due to limited sources of information.

What is "time" for quantum particles?

Physicists from TU Darmstadt propose a new approach to define and measure the time required for quantum tunneling. They suggest using Ramsey clocks, which utilize the oscillation of atoms to determine the elapsed time. The proposed method may correct previous experiments that observed particles moving faster than light during tunneling.

UTA scientists test for quantum nature of gravity

Researchers at UTA used ultra-high energy neutrino particles to search for signatures of quantum gravity, but found no evidence of expected quantum gravitational effects. This non-observation represents a powerful statement about the still-unknown physics operating at the interface of quantum physics and general relativity.

Technical Trials for Easing the (Cosmological) Tension

A new study has sorted through models attempting to solve the cosmological tension, a discrepancy between two ways of calculating the universe's expansion. Three models that were previously viable solutions were excluded by the new data, while others reduced the tension but not solved it.

Down goes antimatter! Gravity's effect on matter's elusive twin is revealed

Researchers confirmed that antimatter falls under the influence of gravity, ruling out gravitational repulsion as a cause for its absence in the universe. The study used an antihydrogen experiment to observe individual atoms taking a downward path, providing a definitive answer to long-standing questions about antimatter's behavior.
