Freakishly Large Viruses With Arms And Tails Found in Massachusetts
These giant viruses have alien-looking appendages and internal structures that have never been seen before.Update:
Scientists resurrect 46,000 year old worms, which instantly started reproducing
New chemical process makes it easier to craft amino acids that don't exist in nature
Every protein in your body is made up of the same 20 building blocks called amino acids. But just because nature is stuck with a limited toolkit doesn't mean humans can't expand it.Scientists Control Human DNA with Electricity in ‘Leap Forward’, Study Reports
Wearable electronic devices are playing a rapidly expanding role in the acquisition of individuals’ health data for personalized medical interventions; however, wearables cannot yet directly program gene-based therapies because of the lack of a direct electrogenetic interface. Here we provide the missing link
Huang et al. develop an interface to allow electrode-mediated stimulation of gene expression in human cells, utilizing direct current-generated reactive oxygen species to stimulate transgene expression downstream of the KEAP1–NRF2 biosensor. In a type 1 diabetic mouse model, this interface is demonstrated to ameliorate hyperglycemia by stimulating insulin expression.
Sun 'umbrella' tethered to asteroid might help mitigate climate change
"In Hawaiʻi, many use an umbrella to block the sunlight as they walk about during the day. I was thinking, could we do the same for Earth and thereby mitigate the impending catastrophe of climate change?"
Earth is rapidly warming and scientists are developing a variety of approaches to reduce the effects of climate change. An astronomer has proposed a novel approach -- a solar shield to reduce the amount of sunlight hitting Earth, combined with a tethered, captured asteroid as a counterweight. Engineering studies using this approach could start now to create a workable design that could mitigate climate change within decades.
Why are people lining up for Worldcoin eyeball scans? “Easy $50”
The overwhelming focus on sign-up bonuses has raised long-standing concerns about whether Worldcoin’s users really understand what they’re signing up for. Last April, twin reports from BuzzFeed News and MIT Technology Review found that the company was using deceptive marketing to induce sign-ups. In simple terms, many users had been drawn in by the promise of free money with little awareness of the broader project.(Thanks to @BlakeL for the submission)
