Scientists at Berkeley Lab are unraveling the mysteries of Bennu, a 4.5-billion-year-old asteroid, using cutting-edge technology.

The asteroid harbors traces of ancient briny water, salty minerals, and even organic molecules – potential clues to life’s origins. Researchers are using X-ray and electron microscopy to analyze these space rocks at the atomic level, revealing how early planetary systems formed. Even more exciting, they’ve found amino acids.

<div class=””> <div class=””><br />Amino acids are a set of organic compounds used to build proteins. There are about 500 naturally occurring known amino acids, though only 20 appear in the genetic code. Proteins consist of one or more chains of amino acids called polypeptides. The sequence of the amino acid chain causes the polypeptide to fold into a shape that is biologically active. The amino acid sequences of proteins are encoded in the genes. Nine proteinogenic amino acids are called “essential” for humans because they cannot be produced from other compounds by the human body and so must be taken in as food.<br /></div> </div>

Experts just discovered massive pools of water that quickly paralyze and kill anything that enters them.

A team of researchers from the University of Miami has discovered deadly deep-sea brine pools in the Red Sea, uncovering a mysterious underwater world where anything that swims in does not survive.

These extreme habitats, found 1.1 miles below the surface, are so salty and oxygen-deprived that they quickly paralyze or kill marine life.

Despite their lethal nature, the outskirts of these pools support unique microbial life, offering scientists new insights into Earth’s climatic history, the origins of life, and even potential extraterrestrial ecosystems. The discovery, published in Nature Communications Earth and Environment, marks the first time such pools have been found so close to shore, making them an invaluable natural archive of past tsunamis, floods, and earthquakes.

S history, these brine pools may also lead to groundbreaking medical advancements. Similar deep-sea microorganisms have previously yielded antibacterial and anticancer compounds, hinting at the potential for new treatments hidden in these depths. Additionally, studying life in such extreme conditions could help scientists understand how organisms might survive on other planets with water-rich environments. This discovery not only expands our understanding of Earth learn more.

Deep-sea brine pools represent hypersaline environments famed for their extremophile microbes. With anoxia entirely excluding bioturbating megafauna, brine pools are also conducive to the pristine preservation of sedimentary sequences. Here we use bathymetric and geophysical observations to locate a complex of brine pools in the Gulf of Aqaba consisting of one 10,000 m2 pool and three minor pools of less than 10 m2. We further conduct sediment coring and direct sampling of the brine to confirm the sedimentary and environmental characteristics of these pools. We find that the main pool preserves a stratigraphy which spans at least 1,200 years and contains a combination of turbidites, likely resulting from flashfloods and local seismicity, and tsunamigenic terrestrial sediment. The NEOM Brine Pools, as we name them, extend the known geographical range of Red Sea brine pools, and represent a unique preservational environment for the sedimentary signals of regional climatic and tectonic events.

How does the armored tiling on shark and ray cartilage maintain a continuous covering as the animals’ skeletons expand during growth?

This is a question that has perplexed Professor Mason Dean, a in the Department of Infectious Diseases and Public Health at City University of Hong Kong (CityUHK) since he was in graduate school.

An expert in , structure and function in vertebrate animals, but with a particular focus on (and affection for) sharks and rays, Professor Dean says he was curious about how nature keeps complex surfaces covered while organs and animals are growing, and their surfaces are changing.

Researchers have characterized the temperature-induced frequency shifts of a thorium-229 nuclear transition—an important step in establishing thorium clocks as next-generation frequency standards.

Atomic clocks are at the core of many scientific and technological applications, including spectroscopy, radioastronomy, and global navigation satellite systems. Today’s most precise devices—based on electronic transitions in atoms—would gain or lose less than 1 second over the age of the Universe. An even more accurate timekeeping approach has recently emerged, based on a clock ticking at the frequency of a nuclear transition of the isotope thorium-229 (229 Th) [1, 2]. Now a collaboration between the teams of Jun Ye of JILA, the National Institute of Standards and Technology, and the University of Colorado Boulder and of Thorsten Schumm of the Vienna Center for Quantum Science and Technology has characterized one of the main sources of the systematic uncertainties that might spoil a clock’s accuracy: temperature-induced shifts of the clock transition frequency [3].

New RNA-based active agents reliably protect plants against the Cucumber mosaic virus (CMV), the most common virus in agriculture and horticulture. They were developed by researchers at the Martin Luther University Halle-Wittenberg (MLU).

The active ingredients have a broad spectrum effect; a series of RNA support the plant’s immune system in combating the virus. In laboratory experiments, 80 to 100% of the treated plants survived an infection with a high viral load, as the team reports in Nucleic Acids Research.

Their paper has been selected as a “breakthrough article” by the journal. The researchers are now working on transferring the idea from the laboratory into practice.

Some notoriously difficult-to-treat infections may not be as resistant to antibiotics as has been thought, according to new research using a microfluidic device that more closely duplicates the fluid flow found in the body than standard cultures.

The University of Illinois Urbana-Champaign research team, led by biochemistry professor Joe Sanfilippo, tested against Pseudomonas aeruginosa, considered one of the most highly resistant pathogens. They introduced the drugs at varying rates of fluid flow and found that, while the bacteria thrived at no or low fluid flow, the antibiotics killed the bacteria at higher flow rates.

“Anytime you take an antibiotic orally or by IV, it’s not immediately in the place it is supposed to be. It will get there by flowing in the bloodstream. Other fluids move throughout the body as well: in the lungs, the , the digestive tract. Yet biologists don’t really study the impact of fluid flow when they study pathogens,” Sanfilippo said.

It’s difficult to build devices that replicate the fluid, precise motion of humans, but that might change if we could pull a few (literal) strings. At least, that’s the idea behind “cable-driven” mechanisms in which running a string through an object generates streamlined movement across an object’s different parts. Take a robotic finger, for example: You could embed a cable through the palm to the fingertip of this object and then pull it to create a curling motion.

While cable-driven mechanisms can create real-time motion to make an object bend, twist, or fold, they can be complicated and time-consuming to assemble by hand. To automate the process, researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed an all-in-one 3D printing approach called “Xstrings.” Part design tool, part fabrication method, Xstrings can embed all the pieces together and produce a cable-driven device, saving time when assembling bionic robots, creating art installations, or working on dynamic fashion designs.

In a paper to be presented at the 2025 Conference on Human Factors in Computing Systems (CHI2025), the researchers used Xstrings to print a range of colorful and unique objects that included a red walking lizard robot, a purple wall sculpture that can open and close like a peacock’s tail, a white tentacle that curls around items, and a white claw that can ball up into a fist to grab objects.

Researchers have mapped the long-range synaptic connections involved in vocal learning in zebra finches, uncovering new details about how the brain organizes learned vocalizations such as birdsong.

The study, published as a Reviewed Preprint in eLife, is described by the editors as having fundamental significance and compelling evidence clarifying how four distinct inputs to a specific region of the brain act on three distinct cell types to facilitate the learning and production of birdsong.

Understanding how the brain integrates sensory and motor information to guide learned vocalizations is crucial for studying both birdsong and human speech. The courtship song of male is a well-studied example of a naturally learned behavior, and is controlled by a set of interconnected forebrain regions in the dorsal ventricular ridge (DVR)—the avian equivalent of the mammalian neocortex.
