Weighing in on the mystery of the gravitational constant

The time had come to open the envelope, but Stephan Schlamminger, a physicist at the National Institute of Standards and Technology (NIST), wasn't sure he wanted to know the secret number that lay inside. For the past 10 years, Schlamminger had spent most of his working hours

Can we trust the science shaping our lives?

Improved methods for social and behavioral sciences research could help enhance public trust in science, says a new study that investigated the robustness of data analysis to understand whether it reliably stood the test of time. It did.

Novel technique drills more detail into ice core records

Glaciers can reveal vast archives of information about Earth's environmental past, but deciphering the origins of the matter within them can be a challenge. Now, using a novel technique that enables researchers to directly analyze millions of individual particles at once, a new

Confirming altermagnetism in an abundant mineral

Also known as magnetoelectronics, spintronics rely on electron spin rather than electron charge, as found in traditional electronics. Although spintronics is still an emerging field, spintronic technologies are already found in hard disk drives and giant magnetoresistance

Sex pheromone of a sandgrain-sized insect deciphered

Parasitic wasps of the genus Trichogramma are among the smallest insects in the world—yet they play an important role in natural ecosystems and agricultural landscapes as natural antagonists of pest species. Research teams from the Universities of Regensburg, Wageningen and

Opioids and other drugs accumulating in freshwater fish

Fish living downstream of wastewater treatment plants are accumulating antidepressants, opioids and other drugs of abuse in their bodies, according to a new study. Using a new analytical method they developed, a team of researchers from the University of Waterloo discovered

Uranus's two outer rings show starkly different origins

Astronomers using the W. M. Keck Observatory on Maunakea, Hawaiʻi Island are revealing new insight into the composition and origins of Uranus's two outer rings. Using data from the Keck Observatory Archive (KOA), combined with observations taken by the Hubble Space Telescope

Navigating the past with ancient stone compass needles

Magnetic rocks with iron oxide concentrations act as natural chroniclers of Earth's past continental movements. Using small samples of rocks, scientists can isolate magnetic grains that were frozen in orientation as the rock solidified. The magnetization of these grains acts as

Massive Atlantic sargassum blooms traced to West Africa

Massive blooms of Sargassum seaweed that have inundated coastlines across the Atlantic since 2011 likely originate off the coast of West Africa—forming years before they are visible and overturning long-standing assumptions about where these events begin.
