Frontiers: The current waste management system within the Extravehicular Mobility Unit (EMU) consists of a disposable diaper—

The Maximum Absorbency Garment (MAG)—that collects urine and feces during extravehicular activities (EVAs) that last up to 8 h. Such exposure to waste for prolonged periods of time contributes to hygiene-related medical events, including urinary tract infections and gastrointestinal distress. Historically, prior to using the MAG, astronauts have limited their food intake or eaten a low-residue diet before embarking on physically demanding spacewalks, reducing their work performance index (WPI) and posing a health risk. Furthermore, the current 0.95 L In-suit Drink Bag (IDB) does not provide sufficient water for more frequent, longer-range spacewalks, which carry greater potential for contingency scenarios requiring extended time away from a vehicle.

Tracking Ozempic’s Nausea Side Effect to Specific Neurons May Lead to Better Drugs

The neurons that produce a sick feeling and food aversion are distinct from those that induce a feeling of fullness.

By Mariana Lenharo & Nature magazine

Next-generation anti-obesity drugs such as Wegovy can melt away weight — but they can also cause intolerable nausea. Now scientists have pinpointed a brain pathway that is involved in this common side effect, raising the prospect of effective weight-loss drugs that don’t make people sick1.

Robot-packed meals are coming to the frozen-food aisle

Advances in artificial intelligence are coming to your freezer, in the form of robot-assembled prepared meals.

Chef Robotics, a San Francisco–based startup, has launched a system of AI-powered robotic arms that can be quickly programmed with a recipe to dole out accurate portions of everything from tikka masala to pesto tortellini. After experiments with leading brands, including Amy’s Kitchen, the company says its robots have proved their worth and are being rolled out at scale to more production facilities. They are also being offered to new customers in the US and Canada.

Watch these hungry waxworms eat through plastic and digest it too

Wriggling critters armed with enzymes can break down plastics that would otherwise take decades, or even centuries to degrade.

At first glance there’s nothing particularly remarkable about waxworms. The larval form of wax moths, these pale wriggling grubs feed on the wax that bees use to make their honeycomb. For beekeepers, the pests are something to swiftly get rid of without a second thought.

But in 2017 molecular biologist Federica Bertocchini, who at the time was researching the embryonic development of vertebrates at the Spanish National Research Council, stumbled on a potentially game-changing discovery about these creatures.

Synthetic Biology is in Fashion

Spider spidroin revives the silken splendor.

In their quest to make silk powerful again, not by status but rather by thread strength, scientists turned to an arachnoid. Dragline silk, the thread by which the spider hangs itself from the web, is one of the strongest fibers; its tensile strength—a measure of how much a polymer deforms when strained—is almost thrice that of silkworm silk.2

Beyond durable fashion garments, tough silk fibers are coveted in parachutes, military protective gear, and automobile safety belts, among other applications, so scientists are keen to pull on these threads. While traditional silk production relies on sericulture, arachnophobes can relax: spider farms are not a thing.

Tiny TnpB: The next-generation genome editing tool for plants unveiled

Genome editing stands as one of the most transformative scientific breakthroughs of our time. It allows us to dive into the very code of life and make precise modifications. Imagine being able to rewrite the genetic instructions that determine almost everything about an organism—how it looks, behaves, interacts with its environment, and its unique characteristics. This is the power of genome editing.

We use genome editing tools to tweak the genetic sequences of microbes, animals, and plants. Our goal? To develop desired traits and eliminate unwanted ones. This technology’s impact has been felt across biotechnology, human therapeutics, and agriculture, bringing rapid advancements and solutions.

The most widely used proteins in genome editing are Cas9 and Cas12a. These proteins are like the scissors of the genetic world, allowing us to cut and edit DNA. However, they are quite bulky, consisting of 1,000–1,350 amino acids. Advanced editing technologies like base editing and prime editing require the fusion of additional proteins with Cas9 and Cas12a, making them even bulkier. This bulkiness poses a challenge to delivering these proteins efficiently into cells, where the resides.

Run screaming or slow retreat? New study sheds light on brain responses to emotionally-charged scenes

The ability to recognize and respond to emotionally-charged situations is essential to a species’ evolutionary success. A new study published in Nature Communications advances our understanding of how the brain responds to emotionally charged objects and scenes.

The research, led by Trinity College Dublin neuroscientist Prof. Sonia Bishop, and Google researcher Samy Abdel-Ghaffar while he was a Ph.D. student in Prof. Bishop’s lab at UC Berkeley, has identified how the represents different categories of emotional stimuli in a way that allows for more than a simple “approach/avoid” dichotomy when guiding behavioral responses.

Sonia Bishop, now Chair of Psychology in Trinity’s School of Psychology, and senior author of the paper, explains, It is hugely important for all species to be able to recognize and respond appropriately to emotionally salient stimuli, whether that means not eating rotten food, running from a bear, approaching an attractive person in a bar or comforting a tearful child.
