The world is going to need a lot of weird metals in the coming years, according to chemistry professor. But he isn't talking about lithium, cobalt or even beryllium. He's interested in dysprosium, which is so hidden in the periodic table that you'd be forgiven for thinking he made it up. Read more ›

Researchers have discovered new ways of preventing and treating respiratory viruses. In two new papers, the team reports the development and validation of NanoSTING, a nasal spray, as a broad-spectrum immune activator for controlling infection against multiple respiratory viruses; and the development of NanoSTING-SN, a pan-coronavirus nasal vaccine, that can protect against infection and disease by all members of the coronavirus family.

Can plasma be sufficiently heated inside a tokamak using only microwaves? New research suggests it can! Eliminating the central ohmic heating coil normally used in tokamaks will free up much-needed space for a more compact, efficient spherical tokamak. Read more ›

The first continent-wide mapping study of plant life across Antarctica reveals growth in previously uncharted areas and is set to inform conservation measures across the region. The satellite survey of mosses, lichens and algae across the continent will form a baseline for monitoring how Antarctica's vegetation responds to climate change. Read more ›

People with higher levels of metals found in their blood and urine may be more likely to be diagnosed with -- and die from -- amyotrophic lateral sclerosis, or ALS, a new study suggests. Investigators also discovered that participants working in occupations with a higher likelihood of metal exposure had increased levels of metal mixtures in their blood and urine. Researchers say by avoiding high risk activities associated with metal... Read more ›

A new study reports the discovery of extremely rare early human fossils from the Indonesian island of Flores, including an astonishingly small adult limb bone. Dated to about 700,000 years old, the new findings shed light on the evolution of Homo floresiensis, the so-called 'Hobbits' of Flores whose remains were uncovered in 2003 at Liang Bua cave in the island's west.

The Pyramid of Djoser, the oldest of Egypt's iconic pyramids, may have been built with the help of a unique hydraulic lift system, according to researchers. A new study suggests that water may have been able to flow into two shafts located inside the pyramid itself, where that water could have been used to help raise and lower a float used to carry the building stones.

Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk... Read more ›

Researchers are in the midst of conducting a first-of-its-kind study to better understand the drivers, demographics, and dynamics of development in the Wildland-Urban Interface, where close proximity to natural areas puts residents at higher-risk for climate-related disasters like fires, flooding, and landslides. A new article explains what trends the research team expects to find and why. Researchers say they hope to demonstrate interconnections between the housing crisis and the climate... Read more ›

A study of horses -- which share many important similarities with humans in their chromosomes and pregnancies -- revealed that 42% of miscarriages and spontaneous abortions in the first two months of pregnancy were due to complications from an extra set of chromosomes, a condition called triploidy.

Understanding neutrino interactions is crucial for obtaining a complete picture of particle physics and the universe. To date, neutrino interaction cross sections have not been measured at high energy above some hundred gigaelectronvolts at particle colliders. Now, researchers have obtained the first direct observation of electron and muon neutrino interactions in the Teraelectronvolt range at CERN's Large Hadron Collider, using the FASER detector. This study marks a significant step for... Read more ›

Melanocytes are responsible for producing melanin, a pigment that shields human skin from the harmful effects of ultraviolet radiation. However, issues arise when the mechanism for renewing dead cells, which helps regulate melanin accumulation, malfunctions. In a study, researchers discovered that the metabolite cyclo(L-Pro-L-Tyr) from Corynebacterium tuberculostearicum effectively inhibits tyrosinase, the enzyme crucial for melanin synthesis. These findings suggest promising applications for cyclo(L-Pro-L- Read more ›

In a study, a cohort of researchers evaluated the effects of state-level insulin out-of-pocket costs across states and payers and over time. The team found that state-level caps on insulin out-of-pocket costs do not significantly increase insulin claims for patients with Type 1 or patients using insulin to manage Type 2 diabetes. Study results could help inform policies aimed at better delivering cost-capped insulin to patients struggling with insulin affordability. Read more ›

Researchers have discovered a new species of sea star (also known as starfish). The discovery came about thanks to collaborative work among researchers, fishers, and aquarium and museum staff. The starfish, which has been named Paragonaster hoeimaruae, belongs to the family Pseudarchasteridae. It is a distinctive red and beige color, with five arms and spans just over 10 centimeters.
