A fresh look at past data reveals that exoplanets with masses similar to Jupiter formed much sooner than previously thought, according to new research. The Ohio State University study’s results provide new information about the timing of accretion—the process of accumulating a large amount of gas as well as solid particles that are rich in…
Researchers have found a link between the sun’s heat and Earth’s seismic activity. Learn more about how this discovery could improve earthquake predictions.

Some bacteria deploy tiny spearguns to retaliate against rival attacks. Researchers at the University of Basel have mimicked attacks by poking bacteria with an ultra-sharp tip. Using this approach, they have uncovered that bacteria assemble their nanoweapons in response to cell envelope damage and rapidly strike back with high precision. Some bacteria deploy tiny spearguns to…
Decades of data following the migratory patterns of endangered caribou show that migration areas have decreased significantly. Researchers are concerned that resource extraction is disturbing caribou habitats.

How can we produce clean hydrogen without burning fossil hydrocarbons or other non-renewable energy sources? We can do so through photoelectrochemistry, or artificial photosynthesis, a method that—just like photosynthesis—uses sunlight and water, as with electrolysis, to obtain hydrogen, without generating harmful emissions. A group of researchers from the Department of Physics of the University of…
Cement manufacturing and repair could be significantly improved by using biocement-producing bacteria, but growing the microbes at construction sites remains a challenge. Now, researchers report a freeze-drying approach in ACS Applied Materials & Interfaces that preserves the bacteria, potentially allowing construction workers to ultimately use powder out of a packet to quickly make tiles, repair…
Lava fountains from a Hawaii volcano reached heights of 600 feet (180 meters) during the latest episode of an eruption that has been pausing and resuming for several months.

Mission engineers at NASA’s Jet Propulsion Laboratory in Southern California turned off the cosmic ray subsystem experiment aboard Voyager 1 on Feb. 25 and will shut off Voyager 2’s low-energy charged particle instrument on March 24. Three science instruments will continue to operate on each spacecraft. The moves are part of an ongoing effort to…
Much like humans generate mountains of garbage, our cells are constantly discarding proteins that are damaged or no longer needed. The cellular waste disposal system called the proteasome is best known for its central role in protein degradation and recycling, but as far back as the 1990s it was shown that products of this process—short…
Motor sport’s governing body the FIA (International Automobile Federation) has not ruled out extending its recent swearing ban to Formula One (F1) team radio communication. Last month FIA president Mohammed Sulayem said the body could “shut down the radios of live communication” over the issue.
