A study in Physical Review Letters has introduced a detector-based way to define gravitational waves in an expanding universe, giving researchers a clearer route from cosmic theory to measurable signals. The work, led by Guillem Domènech with Shi Pi and Ao Wang, tackles a subtle problem at the heart of gravitational-wave cosmology. When the universe…

A study in Diamond and Related Materials found that discarded PET plastic can be converted into highly crystalline synthetic graphite using graphenic additives. The Penn State research points to a possible way to turn a familiar waste stream into carbon materials for future batteries. The result centers on a small but powerful change. When the…
A study in JAMA Neurology found that several healthy eating patterns were linked to better brain aging, with one familiar heart-health plan standing out. In a long-running analysis led by researchers affiliated with Harvard T.H. Chan School of Public Health, the DASH diet showed the strongest association with lower risk of later-life subjective cognitive decline.…
A study in Cell Reports Physical Science found that a commercial sodium-ion battery from China has reached manufacturing quality and power performance comparable to leading lithium-ion cells used in Tesla vehicles. The analysis gives researchers a rare look inside a battery chemistry that could reshape parts of the electric vehicle and grid-storage market. The cell,…
