Fossils suggest microbes were present 3.7 billion years ago, just a few hundred million years after the 4.5-billion-year-old planet had cooled enough to support biochemistry, and many researchers think the hereditary material for...

Visitors to a Swiss zoo caught a glimpse on Friday of a rare albino Galapagos giant tortoise born in May.

Rice University engineers who mimic atom-scale processes to make them big enough to see have modeled how shear influences grain boundaries in polycrystalline materials.

Nobody would have known if I had touched Neil Armstrong’s moon-walking suit back in 2018. I wasn’t supposed to touch it—indeed, I was forbidden to touch it—but boy, I could have. I was in the restoration lab at the National Air and Space Museum’s Udvar-Hazy extension outside of Washington, D.C., and the suit was being mounted on a new mannequin-like armature that...

Cold and wet weather has meant a very slow start to B.C.’s wildfire season, and while that’s expected to continue throughout June, late summer could bring more dangerous conditions, according to the latest fire...

Nearly 43% of patients with non-small cell lung cancer (NSCLC) whose lung cancers harbored a specific KRAS mutation responded to the experimental drug adagrasib, and the targeted agent also showed activity against lesions in the brain that metastasized from the lung tumors, according to results of a new study.

Engineers mimic atom-scale grain boundaries with magnetic particles to see how shear stress influences their movement.

Researchers have created a new type of fiber that can perform like a muscle actuator, in many ways better than other options that exist today. And, most importantly, these muscle-like fibers are simple to make and recycle.

Droplet systems such as DNA droplets, which are formed by liquid-liquid phase separation of macromolecules, play an essential role in cellular functions. Now, by combining the technologies of DNA droplets and DNA computing, computational DNA droplets have been developed, which can recognize specific patterns in tumor biomarker microRNA sequences.

In the fall of 2017, a team of geologists had just set up a new volcanic forecasting modeling program on the Blue Waters and iForge supercomputers. Simultaneously, another team was monitoring activity at the Sierra Negra volcano in the Galapagos Islands, Ecuador. The teams shared their insights and what happened next was the fortuitous forecast of the June 2018 Sierra Negra eruption five months...

The positive test was revealed the same day the CDC reported that there have been 21 confirmed cases across the USA fifth person has tested positive for monkeypox in New York City, local health authorities announced on Thursday, saying “we are monitoring the situation and will investigate any other suspected cases”.This positive test was revealed the same day the federal Centers for Disease...

Researchers in Japan have discovered that the local DNA motion inside of human cells remains steady throughout interphase, where the cell grows and replicates its DNA for cell division. The study suggests that this steady-state DNA motion allows cells to conduct housekeeping tasks under similar environments during interphase.

In the fall of 2017, geology professor Patricia Gregg and her team had just set up a new volcanic forecasting modeling program on the Blue Waters and iForge supercomputers. Simultaneously, another team was monitoring activity at the Sierra Negra volcano in the Galapagos Islands, Ecuador. One of the scientists on the Ecuador project, Dennis Geist of Colgate University, contacted Gregg, and what...

Aqueous droplet formation by liquid-liquid phase separation (or coacervation) in macromolecules is a hot topic in life sciences research. Of these various macromolecules that form droplets, DNA is quite interesting because it is predictable and programmable, which are qualities useful in nanotechnology. Recently, the programmability of DNA was used to construct and regulate DNA droplets formed by...

Carbon dioxide measured at NOAA's Mauna Loa Atmospheric Baseline Observatory peaked for 2022 at 421 parts per million in May, pushing the atmosphere further into territory not seen for millions of years, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today.

The amount of heat-trapping carbon dioxide in the atmosphere has shot past a key milestone—more than 50% higher than pre-industrial times—and is at levels not seen since millions of years ago when Earth was a hothouse ocean-inundated planet, federal scientists announced Friday. The National Oceanic and Atmospheric Administration said its long-time monitoring station at Mauna Loa,...

Nothing I've read about the Baudet du Poitou donkeys prepares me for my first sight of them. They are girthy, with massive round bellies and oversized ears that swoop forward and back, sometimes independently of one another. They are covered in thick hair that hangs in shaggy tufts, "like mammoth fur," says my companion on this adventure in equine medicine, Public Affairs senior photographer...
