NASA receives laser-beamed message from 10 million miles away
Posted by Quinn Sena in category: space
Basically on the pro side it could be something good to help earth but really if is on the bad side we probably want to cloak the earth with an invisibility cloak and force fields ideally so they don’t wipe us out.
An experiment aboard NASA’s Psyche mission achieved “first light” by sending and receiving its first deep-space laser communications from far beyond the moon.

The neuropeptidergic connectome of C. elegans
Posted by Logan Thrasher Collins in categories: biotech/medical, neuroscience
An amazing graph theoretic analysis of the C. elegans neuropeptide connectome!
Neuromodulation by peptides is essential for brain function. By comprehensively mapping neuropeptide signaling in the nematode C. elegans, Ripoll-Sánchez et al. define a dense wireless network whose organization differs in important ways from wired brain circuits. This network is a prototype for understanding neuropeptide signaling networks in larger brains.

The Exciting, Perilous Journey Toward AGI | Ilya Sutskever | TED
Posted by Cecile G. Tamura in categories: business, policy, robotics/AI
Just weeks before the management shakeup at OpenAI rocked Silicon Valley and made international news, the company’s cofounder and chief scientist Ilya Sutskever explored the transformative potential of artificial general intelligence (AGI), highlighting how it could surpass human intelligence and profoundly transform every aspect of life. Hear his take on the promises and perils of AGI — and his optimistic case for how unprecedented collaboration will ensure its safe and beneficial development. (Recorded October 17, 2023)

The brain can exhibit signs of consciousness long after the heart stops, study finds
Posted by Josh Seeherman in category: neuroscience
A study revealed that one-third of cardiac arrest survivors experienced consciousness, with EEG showing brain activity despite heart stoppage. This groundbreaking finding challenges current understandings of brain function during cardiac emergencies.

Scientists Say There May Be Life Under Mercury’s Salt Glaciers
Posted by Josh Seeherman in categories: biological, space
The planet Mercury seems like a place inhospitable to life, with surface temperatures reaching a blistering 800 degrees Fahrenheit due to its extremely close proximity to the Sun.
But new research suggests that there are regions on the Solar System’s smallest planet that may have the right conditions for biological life to survive.
Scientists at the Planetary Science Institute (PSI) in Arizona say they’ve found evidence of salt glaciers on the planet’s surface, regions that are similar to extremely harsh and salt-rich environments on Earth where life still finds a way to exist.

How a textile technology is supercharging stem cell growth
Posted by Arthur Brown in categories: biotech/medical, genetics
Weaving piezoelectric polymers into nanofibers reveals a surprising pathway to boost stem cell growth naturally, without external power.
Our bodies are a complex tapestry of cells, woven into tissues and organs, like bones, muscle, and skin. All these cells begin as blank slates called stem cells, which are directed to become all the unique cell types in the body by a myriad of genetic and environmental cues.
To harness the biomedical potential of stem cells, researchers have long sought ways to untangle these factors and find a recipe to efficiently grow any desired cell type. Now, expertise from textile research is helping create a new platform to achieve this goal.

New human gene cluster sequence discovered
Posted by Dan Breeden in categories: biotech/medical, chemistry, evolution, genetics
Investigators from the laboratory of Ali Shilatifard, Ph.D., the Robert Francis Furchgott Professor and chair of Biochemistry and Molecular Genetics, have discovered a new repeat gene cluster sequence that is exclusively expressed in humans and non-human primates.
The discovery, detailed in a study published in Science Advances, is a breakthrough for human genome biology and has wide-ranging implications for future research in transcriptional regulation, human evolution, and the study of repetitive DNA sequences, according to the authors.
