Computer scientists at the University of California San Diego are showing how soil microbes can be harnessed to fuel low-power sensors. This opens new possibilities for microbial fuel cells (MFCs), which can power soil hydration sensors and other devices.

Led by Department of Computer Science and Engineering (CSE) Assistant Professor Pat Pannuto and Gabriel Marcano, a Ph.D. student working with Pannuto, this research was presented today at the first Association for Computer Machinery (ACM) Workshop on No Power and Low Power Internet of Things.

What happens when an old satellite is no longer in use but can still broadcast? Hacker shenanigans, that’s what.

WASHINGTON — Small launch vehicle company Virgin Orbit says it sees opportunities not just in satellite launch but also in hypersonics as it looks to increase its revenue.

In its first financial results since going public in December after a merger with a special purpose acquisition corporation (SPAC), Virgin Orbit announced March 29 a net loss of $157.3 million for 2021 on $7.4 million in revenue. That compared to a net loss of $121.6 million on $3.8 million in revenue in 2020.

Despite the significant loss, the company emphasized in an earnings call the increase in revenue, primarily from two LauncherOne missions conducted in 2021, as well as a slight improvement in adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA). Virgin Orbit reported an adjusted EBITDA of –$140.4 million in 2021 versus –$157.5 million in 2020.

Last September, the company launched its inaugural rocket but it was intentionally exploded minutes after lifting off.

In addition to its premium vacuums 0, hair styling products 0, and gale-force bathroom hand dryers, Dyson is also known for its air purifiers featuring a bladeless design that makes them quieter and safer, but also a glass HEPA filter inside that promises to remove 99.97% of unwanted air particles in a home like pollen, mold, bacteria, pollution, and odors. There’s even one that can eliminate formaldehyde. That’s great for when you’re at home or the office, but a four-foot tall purifier tethered to a power outlet offers no protection from pollution anywhere else.

The Dyson Zone is the company’s first personal air purification device, and it comes with headphones as a side dish. Trojan-horsed into the high-end bluetooth headset, the Zone offers a buffer of filtration between the wearer and the outside world. When worn out in public, users may feel a bit like Bane from Batman. There may be some awkward stares, but perhaps there will be fewer than expected, thanks to the presence of the headphones.

The company started working on the Zone six years ago. The initial protype was a “snorkel-like clean air mouthpiece paired with a backpack to hold the motor and inner workings,” according to a press release. The final product—over 500 iterations later—is a huge improvement when it comes to design and ergonomics. It still looks like it might take some time to get used to, though maybe less so in the era of Covid-19 than when Dyson’s engineers first started on it.

The two storage companies will jointly develop and promote zoned storage technologies.

Firefly Aerospace has a new majority owner as the Central Texas-based aerospace company prepares for its second rocket launch.

AE Industrial Partners, a private equity firm, has acquired a majority stake in Firefly Aerospace, the company announced.

The Cedar-Park-based company also raised $75 million in a funding round led by AE Industrial Partners. Firefly said it now estimates its valuation at more than $1 billion.

Apple Inc. and Meta Platforms Inc., the parent company of Facebook, provided customer data to hackers who masqueraded as law enforcement officials, according to three people with knowledge of the matter.

Mayo Clinic researchers have proposed a new model for mapping the symptoms of Alzheimer’s disease to brain anatomy. This model was developed by applying machine learning to patient brain imaging data. It uses the entire function of the brain rather than specific brain regions or networks to explain the relationship between brain anatomy and mental processing. The findings are reported in Nature Communications.

“This new model can advance our understanding of how the brain works and breaks down during aging and Alzheimer’s disease, providing new ways to monitor, prevent and treat disorders of the mind,” says David T. Jones, M.D., a Mayo Clinic neurologist and lead author of the study.

Alzheimer’s disease typically has been described as a protein-processing problem. The toxic proteins amyloid and tau deposit in areas of the brain, causing neuron failure that results in clinical symptoms such as memory loss, difficulty communicating and confusion.
