A muscle graft mimics the effects of exercise: it increases strength, muscle mass, and bone density

Scientists have developed a small graft of muscle tissue capable of contracting continuously and managed to reproduce in rats some of the systemic effects associated with physical exercise: increased muscle mass, increased strength and increased bone density. The advance, published in the journal Nature Aging, opens a possible pathway to treat age-related muscle loss in people who cannot exercise.

Rocks can store enough energy to power cities

Portuguese researchers from the GeoBioTec center at Nova University of Lisbon and the Dom Luiz Institute concluded, through theoretical models, that energy storage in underground porous rocks can reach capacities sufficient to supply electricity to a small city. The technique involves storing energy at depth through pressurized fluids in porous rock formations, functioning as a sort of geological battery. This underground storage method represents a potential solution for the growing need for renewable energy storage systems at grid scale.

Dr. Andrea Melo explains study that associates daily bruxism to chronic migraine

Dentist Andréa Melo explains a groundbreaking Brazilian research conducted by the Headache Center Brasil, presented at the 22nd Congress of the International Headache Society, which identified a high prevalence of awake bruxism in patients with chronic migraine. The study, conducted using surface electromyography, showed that both conditions share the same neurological mechanism: hyperactivation of the trigeminal nerve, which runs through the facial muscles. Melo's clinical observation, which she has noted for years in patients referred by neurologists, now has scientific backing.

Eyes on the sky: last partial lunar eclipse of the year happens this early morning

Portugal may observe in the early morning of this Friday, August 28, the last partial lunar eclipse of the year. The phenomenon, which occurs when the Moon partially crosses the shadow projected by Earth, will begin at 2:23 AM with the entry into Earth's penumbra, and the most visible partial phase will begin at 4:12 AM. Earth's shadow will cover part of the lunar surface, altering the appearance of the lunar disk, with the peak of the eclipse occurring near sunrise.
