The ESA is investigating hibernation technology that could allow astronauts to remain healthy during long-duration missions to Mars and beyond.
A renewed era of space exploration is upon us, and many exciting missions will be headed to space in the coming years. These include crewed missions to the Moon and the creation of permanent bases there. Beyond the Earth-Moon system, there are multiple proposals for crewed missions to Mars and beyond. This presents significant challenges since a one-way transit to Mars can take six to nine months. Even with new propulsion technologies like nuclear rockets, it could still take more than three months to get to Mars.

Multiple changes in brain cells during the first month of embryonic development may contribute to schizophrenia later in life, according to a new study by Weill Cornell Medicine investigators.
The researchers, whose study was published in Molecular Psychiatry, used stem cells collected from patients with schizophrenia and people without the disease to grow 3-dimensional “mini-brains” or organoids in the laboratory. By comparing the development of both sets of organoids, they discovered that a reduced expression of two genes in the cells stymies early development and causes a shortage of brain cells in organoids grown from patient stem cells.
“This discovery fills an important gap in scientists’ understanding of schizophrenia,” said senior author Dr. Dilek Colak, assistant professor of neuroscience at the Feil Family Brain and Mind Institute and the Center for Neurogenetics at Weill Cornell Medicine. Symptoms of schizophrenia typically develop in adulthood, but postmortem studies of the brains of people with the disease found enlarged cavities called ventricles and differences in the cortical layers that likely occurred early in life.
All memory storage devices, from your brain to the RAM in your computer, store information by changing their physical qualities. Over 130 years ago, pioneering neuroscientist Santiago Ramón y Cajal first suggested that the brain stores information by rearranging the connections, or synapses, between neurons.
Since then, neuroscientists have attempted to understand the physical changes associated with memory formation. But visualizing and mapping synapses is challenging to do. For one, synapses are very small and tightly packed together. They’re roughly 10 billion times smaller than the smallest object a standard clinical MRI can visualize. Furthermore, there are approximately 1 billion synapses in the mouse brains researchers often use to study brain function, and they’re all the same opaque to translucent color as the tissue surrounding them.

I’ll have what Elon Musk is having.
The revolutionary device could be implanted in human subjects by the end of this year, and some experts believe it could completely revolutionise human sexuality dailystar.
Neuralink, the startup cofounded and run by Elon Musk that hopes to implant computer chips in people’s brains, may have misled federal securities regulators about the billionaire entrepreneur’s role at the company.
That’s according to government documents and Fortune interviews with securities lawyers and a half-dozen former employees of the company. The employees mostly spoke anonymously out of concern for violating nondisclosure agreements and possible retaliation from Musk.
The episode involves a 2018 letter in which an attorney representing Neuralink downplayed Musk’s leadership role at the company in a letter to the Securities and Exchange Commission. The attorney’s characterization contradicts former employees’ accounts, which depict Musk as very much in charge. Neuralink and the attorney involved in the filing did not respond to requests for comment. lawyer for Neuralink told the SEC that Musk had “no executive or management role” at the company. Former employees say that’s far from the truth.
