NASA’s Roman telescope just opened its planet-hunting eye

NASA’s Nancy Grace Roman Space Telescope has completed an important series of tests showing that it can keep its gaze extremely steady during observations. From Sept. 15 to 21, engineers tested Roman’s fine-guidance system, which helps the observatory remain precisely locked onto its targets. Then, on Sept. 22, the telescope’s…

Nearly 6 in 10 people with high blood pressure don’t know they have it

Researchers at Oxford Population Health have found that high blood pressure is going undetected or remains poorly controlled in a large share of adults in England. The team examined blood pressure readings taken in clinics as part of Our Future Health, the UK’s largest health research program. Participants joined the…

97-million-year-old fossils reveal the earliest known animal “GPS”

Researchers have identified what may be the earliest known evidence of an internal animal “GPS” system, offering a possible glimpse into how modern birds, fish, and other creatures evolved the ability to navigate using Earth’s magnetic field. The evidence comes from tiny magnetic fossils dating back 97 million years. They…

The early universe wasn’t nearly as pristine as scientists thought

Only about 500 million years after the Big Bang, when the universe was roughly 3% of its current age, some of the first stars and galaxies had already begun to shine. Astronomers have generally expected that much of the gas around these young galaxies would still have been nearly pristine,…

Scientists just pushed superconductors beyond their usual current limit

Superconductors are among the most remarkable materials in quantum physics. When certain materials are cooled below a specific transition temperature, their electrical resistance disappears. Electricity can then flow through them without losing energy as heat. This happens because electrons form correlated pairs called Cooper pairs. Instead of moving independently, these…

Cancer stem cells have an “energy addiction” scientists may be able to exploit

Researchers at the University of Colorado Anschutz Cancer Center have uncovered a previously unknown metabolic vulnerability in the stem cells responsible for high risk myelodysplastic syndromes (MDS). The finding could eventually help scientists develop treatments that more precisely target the cells driving this aggressive blood cancer. The study, published in…

Even one strength training session a week could make a difference

Healthy aging is about staying independent, maintaining mobility and continuing to enjoy everyday activities as you get older. For many people, what matters most is being able to get out of a chair without help, carry shopping home, climb the stairs and recover quickly after illness. One of the most…

Festa dei nonni, in Italia sono oltre 12 milioni – Notizie – Ansa.it

Si celebra oggi, 2 ottobre, la Festa dei nonni. La data della ricorrenza non è casuale perché coincide con la ricorrenza cattolica dei Santi Angeli Custodi. Alla Festa dei Nonni, istituita nel 2005, la legge riserva nonni un onore ed una considerazione particolare. Se infatti il papa’ e la mamma…

Estate 2026, la più calda di sempre in Europa Occidentale – Dossier – Ansa.it

L’Europa occidentale ha registrato l’estate più calda mai rilevata, con una temperatura media di 21,7 gradi centigradi, ovvero 2,5 gradi al di sopra della media del periodo 1991-2020, superando il precedente record stabilito nel 2003. Lo afferma Copernicus precisando che il caldo eccezionale si è esteso ben oltre i mesi…

Weak sunlight can still damage your DNA, scientists warn

A landmark study from QIMR Berghofer has found that even relatively brief periods outdoors during times of weaker sunlight can damage the skin and add to skin cancer risk. The results challenge the long standing assumption that spending time outside early or later in the day is largely harmless. Total…

Electrons slow to a crawl in a strange new quantum state

Over the past decade, scientists have made major progress in creating two-dimensional materials with unusual quantum properties that could eventually support a new generation of technologies. Some of these materials can become superconductors, allowing electricity to flow without energy loss, while others develop charge orders, in which electrons settle into…

Scientists may have found a “unifying theory” of chronic fatigue

Researchers at the University of East Anglia and Oxford BioDynamics have identified a possible biological connection that could help explain why profound exhaustion appears across conditions as different as long Covid and PTSD. The new study, published in the Journal of Translational Medicine, points to striking similarities in the biology…
