140-year-old Rusty Batteries Offer Huge Breakthrough For Energy Storage

Posted by in categories: energy, sustainability, transportation

While it may be too late for the breakthrough to allow mass adoption for consumer electronics and electric vehicles, Professor Chiang believe it could revolutionise energy storage for large-scale renewable operations.

He has founded a startup, Form Energy, to further develop and commercialise the technology, with the hope of rapidly pushing forward zero carbon energy solutions.

Ready, Set…Go! Brain Circuit That Triggers the Execution of Planned Movement Discovered

Posted by in category: neuroscience

Summary: Researchers have identified a neural circuit that helps suppress the execution of planned actions in response to specific cues.

Source: Max Planck Florida.

Planned movement is essential to our daily lives, and it often requires delayed execution. As children, we stood crouched and ready but waited for the shout of “GO!” before sprinting from the starting line. As adults, we wait until the traffic light turns green before making a turn. In both situations, the brain has planned our precise movements but suppresses their execution until a specific cue (e.g., the shout of “GO!” or the green light).

Can We Resurrect Extinct Species? Scientists Put Jurassic Park to the Test

Posted by in categories: biotech/medical, education, existential risks, genetics

De-extinction grabbed our imagination in the 90s with Jurassic Park. Scientists have since asked: how possible is it?

According to a new study, nearly impossible. But wait—it’s not all bad news. While bringing back a faithful copy of an extinct species may be impossible, we could bring back a hybrid species that’s a genetic mix between an extinct species and its modern descendant.

Published in Current Biology, the study eschews the grandiose mammoth, instead focusing on a tiny test case: the Christmas Island rat. Hefty in size and loudly vocal when invading docked ships and their cargo, the rodents were last seen in the 1900s. With a stroke of luck, the team recovered DNA from two well-preserved museum samples and compared them against a close relative: the Norway brown rat, a popular lab model for genetic studies today.

Is Dark Matter In The Room With Me Right Now? Scientists Say Yes

Posted by in category: cosmology

We don’t wanna freak you out, but there’s a serious likelihood that dark matter could be in the room with you right now, and could even be passing through your body as you read this.

“Yeah, absolutely. It’s here,” Yeshiva University researcher Ed Belbruno told Futurism. “Where you’re sitting, you’re feeling, on some level which is beyond our senses… that force.”

It makes sense. Dark matter, which scientists have yet to observe or measure directly, is estimated to make up 95 percent of the universe. With a substance that prevalent, the likelihood that it’s made its way to Earth and into our homes and bodies seems high, right?

NASA Rover Detects Organic Molecules on the Surface of Mars

Posted by in category: space

While it’s an exciting discovery, it falls short of demonstrating that carbon-based lifeforms once lived on the surface of the Red Planet. It is, however, a step in that direction.

“This experiment was definitely successful,” Maëva Millan, postdoctoral fellow at NASA’s Goddard Spaceflight Center and lead author of a new study published on Monday in the journal Nature Astronomy, told Inverse.

“While we haven’t found what we were looking for, biosignatures, we showed that this technique is really promising,” she added.

Materials scientists discover why perovskite solar cells degrade in sunlight

Posted by in categories: solar power, sustainability

Materials scientists at the UCLA Samueli School of Engineering and colleagues from five other universities around the world have discovered the major reason why perovskite solar cells—which show great promise for improved energy-conversion efficiency—degrade in sunlight, causing their performance to suffer over time. The team successfully demonstrated a simple manufacturing adjustment to fix the cause of the degradation, clearing the biggest hurdle toward the widespread adoption of the thin-film solar cell technology.

A detailing the findings was published today in Nature. The research is led by Yang Yang, a UCLA Samueli professor of materials science and engineering and holder of the Carol and Lawrence E. Tannas, Jr., Endowed Chair. The co-first authors are Shaun Tan and Tianyi Huang, both recent UCLA Samueli Ph.D. graduates whom Yang advised.

Perovskites are a group of materials that have the same atomic arrangement or crystal structure as the mineral calcium titanium oxide. A subgroup of perovskites, , are of great research interest because of their promising application for energy-efficient, .
