NASA is looking for ways to get rock samples back from Mars for less than the $11 billion the agency would need under its own plan, so last month, officials put out a call to industry to propose ideas.

Boeing is the first company to release details about how it would attempt a Mars Sample Return mission. Its study involves a single flight of the Space Launch System (SLS) rocket, the super heavy-lift launcher designed to send astronauts to the Moon on NASA's Artemis missions.

Jim Green, NASA's former chief scientist and longtime head of the agency's planetary science division, presented Boeing's concept Wednesday at the Humans to Mars summit, an annual event sponsored primarily by traditional space companies. Boeing is the lead contractor for the SLS core stage and upper stage and has pitched the SLS, primarily a crew launch vehicle, as a rocket for military satellites and deep space probes.

There are few things more heartwarming than videos of children with deafness gaining the ability to hear, showing them happily turning their heads at the sound of their parents' voices and joyfully bobbing to newly discovered music. Thanks to recent advances in gene therapy, more kids are getting those sweet and triumphant moments—with no hearing aids or cochlear implants needed.

At the annual conference of the American Society for Gene & Cell Therapy held in Baltimore this week, researchers showed many of those videos to their audiences of experts. On Wednesday, Larry Lustig, an otolaryngologist at Columbia University, presented clinical trial data of two children with profound deafness—the most severe type of deafness—who are now able to hear at normal levels after receiving an experimental gene therapy. One of the children was 11 months old at the time of the treatment, marking her as the youngest child in the world to date to receive gene therapy for genetic deafness.

On Thursday, Yilai Shu, an otolaryngologist at Fudan University in Shanghai, provided a one-year progress report on six children who were treated in the first in-human trial of gene therapy for genetic therapy. Five of the six had their hearing restored.

A US district judge William Alsup has dismissed Elon Musk's X Corp's lawsuit against Bright Data, a data-scraping company accused of improperly accessing X (formerly Twitter) systems and violating both X terms and state laws when scraping and selling data.

X sued Bright Data to stop the company from scraping and selling X data to academic institutes and businesses, including Fortune 500 companies.

According to Alsup, X failed to state a claim while arguing that companies like Bright Data should have to pay X to access public data posted by X users.

Diehard fans of cold-brew coffee put in a lot of time and effort for their preferred caffeinated beverage. But engineers at the University of New South Wales, Sydney, figured out a nifty hack. They rejiggered an existing espresso machine to accommodate an ultrasonic transducer to administer ultrasonic pulses, thereby reducing the brewing time from 12 to 24 hours to just under three minutes, according to a new paper published in the journal Ultrasonics Sonochemistry.

As previously reported, rather than pouring boiling or near-boiling water over coffee grounds and steeping for a few minutes, the cold-brew method involves mixing coffee grounds with room-temperature water and letting the mixture steep for anywhere from several hours to two days. Then it is strained through a sieve to filter out all the sludge-like solids, followed by filtering. This can be done at home in a Mason jar, or you can get fancy and use a French press or a more elaborate Toddy system. It's not necessarily served cold (although it can be)—just brewed cold.

The result is coffee that tastes less bitter than traditionally brewed coffee. “There’s nothing like it,” co-author Francisco Trujillo of UNSW Sydney told New Scientist. “The flavor is nice, the aroma is nice and the mouthfeel is more viscous and there’s less bitterness than a regular espresso shot. And it has a level of acidity that people seem to like. It’s now my favorite way to drink coffee.”
