“I wouldn’t want to be on the team figuring out how to build a Jupiter-sized spacecraft, but the odds aren’t zero.”

A team of scientists believes we may be able to detect alien spacecraft flying through distant solar systems using the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the US.

Though the scientists from Applied Physics, a research institute in New York, concede that gravitational wave (GW) detection is “in its infancy”, they also say it is “a sophisticated science” that could be used to “detect extra-terrestrial mega-technology,” in a paper available in pre-print server arXiv.

Achieving a long-sought goal of regenerative medicine.

Researchers from the University of California, San Francisco, (UCSF) engineered molecules that function as “cellular glue,” enabling them to precisely direct how cells bond with each other. This is a significant step toward regenerative medicine’s long-term goal of creating new tissues and organs, according to a press release.

Adhesive molecules are naturally present in the body and keep the tens of trillions of cells together in organized patterns. They build neural networks, develop structures, and direct immune cells to specific areas of the body. Adhesion also makes cell communication easier to maintain the body functioning as a self-regulating whole.

Could video streaming be as bad for the climate as driving a car? Calculating Internet’s hidden carbon footprint.

We are used to thinking that going digital means going green. While that is true for some activities — for example, making a video call to the other side of the ocean is better than flying there — the situation is subtler in many other cases. For example, driving a small car to the movie theatre with a friend may have lower carbon emissions than streaming the same movie alone at home.

How do we reach this conclusion? Surprisingly, making these estimates is fairly complicated.

The Japanese are reliable partners in this mission.

Even before NASA’s Artemis I mission successfully splashed down in the Pacific Ocean, NASA chief Bill Nelson was preparing for the next phase of the mission, of sending crewed missions to the Moon. In an interview with Nikkei.

While details on how the spacecraft performed during its 25.

FTX’s fallen CEO, Sam Bankman-Fried, is scheduled to testify tomorrow as a witness before the U.S. House of Representatives Committee on Financial Services.

The committee is investigating the events that led up to FTX’s implosion, which resulted in the crypto exchange filing for bankruptcy last month. Prior to Bankman-Fried testifying, John J. Ray III, the new CEO of FTX, will speak to the House during its first panel.

The hearing, “Investigating the Collapse of FTX, Part I,” sounds like a movie title — and some parts of it probably feel like one, given how crazy this whole situation has become. But questions surrounding what really happened at FTX may remain unanswered; even though Bankman-Fried is scheduled to testify, there are still concerns he may get cold feet.

Overnight, news broke that the National Ignition Facility, a U.S. government research lab, was the first to achieve net-positive nuclear fusion. When lasers hit the tiny fuel pellet, it created an explosion that released more energy than the lasers delivered.

For decades, fusion power has been just around the corner. Is this the moment we’ve all been waiting for?

Maybe.

World Food Day, celebrated every year on 16 October, marks the founding of the Food and Agriculture Organization (FAO) of the United Nations in 1945 as an organization that deals with global food and agricultural issues. The number of people going hungry has increased since 2014 and the prevalence of undernourishment has remained virtually unchanged in the past 3 years. This reversal in progress sends a clear warning that more must be done urgently if the Sustainable Development Goal of Zero Hunger is to be achieved by 2030.

A spinning top submerged in a liquid can make a striking fractal structure.

Fractals are patterns and structures that repeat themselves at smaller scales when zoomed in. Bavand Keshavarz and Michela Geri at the Massachusetts Institute of Technology were studying how one liquid breaks up into droplets when it is mixed into another and unexpectedly discovered a new kind of liquid fractal.

Summary: A new study aims to investigate the interaction between the digestive and nervous systems, or the gut-brain axis, to discover more about the links between digestive health and neurodegenerative diseases.

How do the gut and the brain interact, and can this even trigger disease?
