New research has revealed that the lag observed in organic electrochemical transistors (OECTs) when switched on is due to a two-step activation process, providing crucial insights for designing more effective and customizable OECTs for various technological and biological applications.

Researchers who want to bridge the divide between biology and technology spend a lot of time thinking about translating between the two different “languages” of those realms.

“Our digital technology operates through a series of electronic on-off switches that control the flow of current and voltage,” said Rajiv Giridharagopal, a research scientist at the University of Washington. “But our bodies operate on chemistry. In our brains, neurons propagate signals electrochemically, by moving ions — charged atoms or molecules — not electrons.”

A naturally occurring sugar called 2-deoxy-D-ribose (2dDR) may boost hair growth.

Did life ever exist on Mars, and if so, how did it get there? This is the goal of NASA’s Curiosity rover, which has traversed Gale Crater on Mars since 2012. But a recent finding by the car-sized robotic explorer could help bring scientists one step closer to answering these questions as Curiosity sent back images of yellow crystals revealed to be deposits of elemental sulfur, along with an entire field of them. This finding was accidentally “un-earthed” as Curiosity drove over them during its excursions. While scientists didn’t anticipate finding elemental sulfur in this region, this finding could hold the potential to help piece together the geologic history of Gale Crater and whether life once existed there.

“Finding a field of stones made of pure sulfur is like finding an oasis in the desert,” said Dr. Ashwin Vasavada, who is a project scientist on Curiosity at NASA’s Jet Propulsion Laboratory. “It shouldn’t be there, so now we have to explain it. Discovering strange and unexpected things is what makes planetary exploration so exciting.”

The fighter’s new engines can power laser weapons and enable a “pilot optional” mode.

How many Earth-like planets exist throughout the universe? This is what recent talk given at the National Astronomy Meeting 2024 hopes to address as Dr. David Brown, who is a scientist on the European Space Agency’s (ESA) PLATO (PLAnetary Transits and Oscillations of stars) mission, provided an update on the mission and the goals it hopes to achieve. This comes as PLATO is currently scheduled to launch in December 2026 with the goal of finding Earth-like planets throughout the universe, which could greatly expand our knowledge of exoplanets, as well.

“PLATO’s goal is to search for exoplanets around stars similar to the Sun and at orbital periods long enough for them to be in the habitable zone,” said Dr. Brown. “One of the main mission objectives is to find another Earth-Sun equivalent pair, but it is also designed to carefully and precisely characterize the exoplanets that it finds (i.e. work out their masses, radii, and bulk density).”

Nanotransfection is very useful and could be used as a way to heal oneself on a smartphone in one touch with cell reprogramming and much more like gene transfer.

Tissue nanotransfection (TNT), a cutting-edge technique of in vivo gene therapy, has gained substantial attention in various applications ranging from in vivo tissue reprogramming in regenerative medicine, and wound healing to cancer treatment. This technique harnesses the advancements in the semiconductor processes, facilitating the integration of conventional transdermal gene delivery methods—nanoelectroporation and microneedle technologies. TNT silicon chips have demonstrated considerable promise in reprogramming fibroblast cells of skin in vivo into vascular or neural cells in preclinical studies to assist in the recovery of injured limbs and damaged brain tissue. More recently, the application of TNT chips has been extended to the area of exosomes, which are vital for intracellular communication to track their functionality during the wound healing process.

Fusion vessels have a Goldilocks problem: The plasma within needs to be hot enough to generate net power, but if it’s too hot, it can damage the vessel’s interior. Researchers at the Princeton Plasma Physics Laboratory (PPPL) are exploring ways to draw away excess heat, including several methods that use liquid metal.

One possibility, say researchers at the U.S. Department of Energy Lab, involves flowing liquid lithium up and down a series of slats in tiles lining the bottom of the vessel. The liquid metal could also help to protect the components that face the plasma against a bombardment of particles known as neutrons.

“The prevailing option for an economical commercial fusion reactor is a compact design,” said PPPL’s Egemen Kolemen, co-author of a 2022 paper on the research and an associate professor of mechanical and aerospace engineering and the Andlinger Center for Energy and the Environment. However, compactness makes handling the heat flux and neutron bombardment a bigger challenge.
