Spacewalks, Brain Mapping, and a T. Rex Named Gus Heads to Auction

Russian cosmonauts completed a six-hour spacewalk at the International Space Station, installing a solar radiation telescope, retrieving science experiments, and inspecting a stuck antenna on a cargo craft — a reminder that technical cooperation between Russian and American teams continues despite profound diplomatic tensions on Earth.

Researchers used physics-informed artificial intelligence to map cerebrospinal fluid flow through the brain's glymphatic system for the first time, identifying two distinct speeds of fluid movement. The glymphatic system clears metabolic waste from brain tissue during sleep, and disruptions have been linked to Alzheimer's disease, making the mapping a potentially significant step toward new therapies.

NASA's administrator described SpaceX as 'hands down' the leading space company, a notable endorsement from an agency that historically relied on traditional aerospace contractors. The Hubble Space Telescope, meanwhile, captured new imagery of a faint dwarf galaxy twenty-three million light-years away, continuing its scientific mission despite aging hardware.

In energy, Avangrid signed a one-hundred-forty-megawatt solar deal with Microsoft in Washington state, while a separate report found that more than half of the three hundred twenty-two energy projects announced across Africa in twenty twenty-five were solar initiatives, marking a decisive shift in the continent's energy development trajectory.

Sotheby's announced it will auction a T. rex skeleton named 'Gus' for an expected price of up to thirty million dollars, reigniting debate over whether high-value fossil sales remove scientifically significant specimens from public research access.
