Researchers at Kyushu University have found that an ultrathin layer of iridium manganese (IrMn) can improve two spin-related signals in a structure made of a magnetic insulator and a platinum film. By examining how spin currents are generated and absorbed, the team gained insight
Planning a successful trip can be challenging, especially when your destination is in outer space. Even before liftoff, space missions require extraordinary amounts of scientific preparation and data analysis to succeed, which can take years to complete. However, as space agencie
My grandmother was a Holocaust survivor from Kostopol, Ukraine. Years after she passed away, I was trying to learn more about her life before the war—something I knew very little about. When I found a book called "Sefer Kostopol"—Hebrew for "Book of Kostopol"—I hoped to find her
New research by a Florida State University professor in the Herbert Wertheim College of Business finds that America's increasingly polarized political system reaches far beyond the ballot box, creating greater uncertainty and higher costs for companies.
To limit further climate change, researchers are exploring technologies that can convert atmospheric carbon dioxide (CO₂) into useful products. In collaboration with BOKU University in Vienna (Austria), researchers at the Helmholtz Centre for Environmental Research (UFZ) have dem
The gender balance among the top scorers on Advanced Placement exams tends to track the gender balance among students taking those tests, according to a new study led by the University of Georgia.
In Australia, around 2,000 people are on the waiting list to receive an organ transplant, but thanks to new research being undertaken at the University of New England (UNE), this number could someday be significantly reduced.
High on the Qinghai-Xizang Plateau, the ground stays frozen, with only the top few meters melting each summer. Although the region is warming about twice as fast as the global average, a new study finds that more than a third of its permafrost, mainly in the central plateau, has
Dead tree branches are by no means static but move throughout the day. Geoinformatics researchers at Heidelberg University tracked these movements in a study conducted in cooperation with the Finnish Geospatial Research Institute (FGI).
Scientists discover the immune system’s hidden sense of touch and more — today's student signal.
Scientists at McGill University have discovered a surprising new ability of immune cells that could change how we understand long-term immunity. Researchers found that T cells can actually sense how stiff their surrounding tissues are, using these physical signals to help determi
Rainfall reductions of up to 80% and torrential precipitation leading to severe flooding and landslides are the expected consequences across different areas of Latin America and the Caribbean from the impact of the El Niño phenomenon in 2027, according to a report co-authored by
A new study has found that in U.S. counties that ended COVID-19 pandemic-era Supplemental Nutrition Assistance Program (SNAP) Emergency Allotments, child maltreatment rates went up. The findings from the study in the American Journal of Preventive Medicine suggest that changes to
Researchers have discovered a small group of brain cells that prevents dangerous blood pressure swings, even when average readings appear normal. The finding reveals a hidden source of cardiovascular risk and could open the door to new treatments that protect the heart and brain.
Scientists have defied a long-standing rule of laser physics by generating X-rays with much higher energies than conventional theory predicts. The surprising discovery reveals how two electrons working together can overcome a previously accepted limit, opening new possibilities f
Scientists have uncovered seven surprising stages that space rocks go through as they hurtle toward Earth, revealing that melting and violent fragmentation, rather than simple evaporation, determine their fate. The discovery could help explain why meteorites scatter across the gr
A new report co-authored by researchers from the University of York and WWF highlights how local communities across the U.K. imagine positive, sustainable, and resilient futures for the places where they live and work.
Scientists have discovered that magma deep inside Earth can store surprising amounts of extra oxygen, potentially revealing a hidden contributor to our planet's oxygen-rich atmosphere. The findings suggest that ancient volcanic eruptions may have helped transform Earth's atmosphe
When we think about Europe's winter weather, the Indian Ocean is probably not the first place we look. We might picture Atlantic storms, cold air arriving from the north or rain sweeping across the Mediterranean. In my research, however, I look at how these familiar weather syste
There are two lighthouses on Lady Elliot Island, at the southernmost tip of Australia's Great Barrier Reef. The first was built in 1873, but was decommissioned in 1995 when the second took over the job of warning ships off the reef. Visitors to the island, however, regularly repo
Researchers at Kyushu University have found that an ultrathin layer of iridium manganese (IrMn) can improve two spin-related signals in a structure made of a magnetic insulator and a platinum film. By examining how spin currents are generated and absorbed, the team gained insight
Two nearly identical materials have completely different chemical behavior. Research teams at the University of Vienna and TU Wien studied catalysts that use the energy of sunlight to produce ammonia. Surprisingly, when the three iron atoms that form tiny triangles in these catal
Macromolecular crowding can serve as a design tool for controlling the formation and organization of synthetic DNA droplets, a study from Science Tokyo reveals. Researchers investigated this strategy using DNA nanostars and polymeric crowding agents to mimic the crowded cellular
An international study investigating why wild tomatoes are more resistant to the tomato leafminer (Phthorimaea absoluta) than cultivated varieties revealed that the secret lies in the spatial structure of a plant defense molecule. The researchers mapped the biochemical origin of
