Phys.org / Rare pulsar unleashes 114 giant pulses in a single hour

Astronomers have detected extreme, never-before-seen behavior from a rare kind of pulsar and stumbled on a surprising link to one of astronomy's biggest current mysteries. Using 174 hours of radio observations, researchers ...

Medical Xpress / Different daily step count and stepping pace combos may all lower the risk of early death

Fewer daily steps at a faster pace or more steps at a slower pace may both substantially lower the risk of an early death, with a brisker pace for at least 30 minutes a day the potential sweet spot for those with sedentary ...

Phys.org / Cosmic radiation at flight altitudes rises when the sun is less active

Radiation from space is constantly entering Earth's atmosphere, but how much of it reaches the altitudes used by commercial aircraft depends not only on height and location, but also on the activity of the sun. A new study ...

Phys.org / Tiny molecular rings open new ways for designing better medicines

Cyclopropanes are organic chemistry's smallest rings. Three carbon atoms are joined in a triangle, creating a compact and unusually strained structure. Despite—or partly because of—this unusual geometry, cyclopropanes are ...

Phys.org / Giant impacts may strip small icy moons of subsurface oceans

Southwest Research Institute (SwRI) scientists used simulations to understand the role disruptive impacts play on icy moons with subsurface oceans in our solar system. A recent paper published in the journal Nature Astronomy ...

Phys.org / Waterlogged seeds reveal melons' ancient journey

Melons produce many seeds, making the melon shape a traditional symbol of fertility and prosperity in Chinese culture. But the historical debate about how melons made their way to modern tables is as long and twisted as ...

Medical Xpress / This is how dense breast tissue may lead to cancer

Breast cancer often grows in tissue that is unusually dense. That's why clinicians flag women with this kind of breast tissue for follow-up after a mammogram.

Phys.org / Fast radio bursts could help disentangle galactic feedback from dark matter effects

Intense, brief flashes of radio light called fast radio bursts (FRBs) travel across billions of light-years to reach Earth, passing through a fog of matter along the way. The bursts' origins are unclear but may originate ...

Phys.org / Sparse-data method estimates sea surface temperatures 40% more accurately than conventional approach

Researchers have developed a method for extrapolating sea surface temperatures from sparse data that is significantly more accurate than other commonly used computational methods and slightly more accurate than the best-performing ...
