A map of the entire human brain could help us understand where diseases come from, to how we store memories. But mapping the brain with today’s technology would take billions of dollars and hundreds of years. Learn what GR has already revealed about the brain, and how it’s making it easier for scientists to—someday—reach this goal.

How can long-term space flight influence astronaut health, and specifically their organs? This is what a recent study published in Nature Communications hopes to address as a large team of international researchers conducted the most comprehensive study regarding astronaut kidney health and how it’s affected from both microgravity and galactic cosmic radiation (GCR) during long-term space missions. This study holds the potential to help astronauts, space agencies, medical professionals, and the public better understand the health risks associated with sending humans to other worlds, specifically to Mars.
“We know what has happened to astronauts on the relatively short space missions conducted so far, in terms of an increase in health issues such as kidney stones,” said Dr. Keith Siew, who is a Research Fellow in the Department of Renal Medicine at the University of College London (UCL) and lead author of the study. “What we don’t know is why these issues occur, nor what is going to happen to astronauts on longer flights such as the proposed mission to Mars.”
Aside from the 24 Apollo astronauts who traveled to the Moon, with 12 of them walking on the surface, nearly all human space travel has been limited to low-Earth orbit (LEO), totaling almost 700 people having traveled to space. During this time, they are protected by the Earth’s magnetic field, which shields them from harmful solar and cosmic radiation that could cause potentially irreparable harm to their health.
Diabetic wounds are slow-healing, potentially life-threatening complications with limited treatment options. But a two-step, nanomaterial-based strategy may open doors to better care.
Stanford researchers have developed a speech brain-computer interface (BCI) they say can translate thoughts into text at a record-breaking speed — putting us closer to a future in which people who can’t talk can still easily communicate.
The challenge: “Anarthria” is a devastating condition in which a person can’t speak, despite being able to understand speech and knowing what they want to say. It’s usually caused by a brain injury, such as a stroke, or a neurological disorder, such as Parkinson’s disease or ALS.
Some people with anarthria write or use eye-tracking tech to communicate, but this “speech” is far slower than the average talking speed. People with anarthria due to total paralysis or locked-in syndrome can’t even move their eyes, though, leaving them with no way to communicate.
Lasers have revolutionized the world since the 60s and are now indispensable in modern applications, from cutting-edge surgery and precise manufacturing to data transmission across optical fibers.
This interview with Yip Thy Diep Ta, CEO of J3d.ai, delves into AI-driven collective intelligence for decision-making, ethical considerations in AI development (fairness, bias mitigation, diversity), the implications of human-machine integration technologies (e.g., Neuralink), and the evolving role of humans in an AI-driven workforce.

#AI #AGI #Futureofwork.
SingularityNET was founded by Dr. Ben Goertzel with the mission of creating a decentralized, democratic, inclusive, and beneficial Artificial General Intelligence (AGI). An AGI is not dependent on any central entity, is open to anyone, and is not restricted to the narrow goals of a single corporation or even a single country.
Oncologists have grown increasingly excited about “antibody drug conjugates,” which allow for the use of more potent chemotherapy agents with fewer side effects.
A team from the Innovative Genomics Institute at the University of California, Berkeley (UCB) has produced an increase in gene expression in a food crop by changing its upstream regulatory DNA. While other studies have used CRISPR/Cas9 gene-editing to knock out or decrease the expression of genes, new research published in Science Advances is the first unbiased gene-editing approach to increase gene expression and downstream photosynthetic activity.
Many people associate aging with a decline in cognitive function, health issues, and reduced activity. Uncovering mental processes that can boost the well-being of the older adults could be highly beneficial, as it could help to devise more effective activities aimed at improving their quality of life.
Researchers at University of Brescia and the Catholic University of the Sacred Heart recently carried out a study investigating the contribution of creativity and humor to the well-being of the elderly. Their findings, published in Neuroscience Letters, show that these two distinct human experiences share common psychological and neurobiological processes that promote well-being in older adults.
“Our recent study belongs to a line of research aimed at investigating the cognitive resources which are still available to elderly people and at understanding how such resources can support well-being,” Alessandro Antonietti, co-author of the paper, told Medical Xpress.
Yale researchers are using chemical “chameleons” to sneak up on drug-resistant brain tumors.
A Yale Cancer Center team has synthesized a compound, KL-50, that they say selectively targets drug-resistant glioblastomas while leaving healthy tissue alone.
Yale scientists say KL-50, their lead “chameleon” compound, effectively targets tumors without harming healthy surrounding tissue.
