When life emerged, it did so quickly. 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...

On 16 May, planetary scientist Laurie Leshin became director of NASA’s Jet Propulsion Laboratory (JPL), one of the world’s leading labs for robotic space science. Coming off the successful landing of the Perseverance rover on Mars, JPL is readying several more...
Rare albino Galapagos giant tortoise born in Swiss zoo
Visitors to a Swiss zoo caught a glimpse on Friday of a rare albino Galapagos giant tortoise born in May.
Engineers model nanoscale crystal dynamics in easy-to-view system
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.
New Lunar Spacesuits to Set NASA Back $3.5 Billion
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...
Wet weather means slow start to B.C. wildfire season, but forecast suggests shift in July
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...
Let doctors use MDMA to treat veterans with PTSD and depression, former ADF boss says
Chris Barrie says he hopes common sense will prevail and the TGA will allow drug to be more readily used to treat patientsGet our free news app; get our morning email briefingThe former chief of the Australian defence force, Chris Barrie, is campaigning to remove barriers stymying doctors from using MDMA to treat veterans suffering post-traumatic stress disorder and depression, saying he hopes...

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.
Grain boundaries go with the flow

- 22/6/3 21:33
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.
Novel method for early disease detection using DNA droplets
- ScienceDaily
- 22/6/3 21:33
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.
Great timing, supercomputer upgrade lead to successful forecast of volcanic eruption
- ScienceDaily
- 22/6/3 21:33
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...
