Watch this spider crawl like an ant to avoid being eaten

Unlike some other spiders that camouflage themselves with drab colors and sticklike appendages, the jumping spider Siler collingwoodi disguises itself by the way it moves. The bright blue and orange arachnid—a pea-size animal native to China and Japan—crawls like an ant, according to a new study.

In a side-by-side comparison, researchers found that S. collingwoodi spiders copied the movements of multiple spikey, aggressive species of ants. The spiders walked at a similar pace, bobbed their abdomens like the ants did, and elevated their first pair of legs when they walked, imitating antennae.

New lidar system maps location, speed and material properties in a single measurement

Researchers have developed a new kind of lidar system that simultaneously measures the location, speed and material properties of objects in a scene. This type of information could be useful for applications such as robotics, autonomous driving and remote sensing.

Lidar uses laser pulses to measure distances and create highly detailed 3D maps of objects and terrain. However, most commercial lidar systems, such as those used in autonomous cars, primarily measure distance.

“Although some emerging lidar technologies can also measure velocity, real-world perception often requires understanding an object’s surface as well,” said Dongyu Du from the University of Toronto in Canada. “Our new system uses a single measurement at each scanned point to capture millimeter-accurate distance, velocity and surface material while using eye-safe laser power.”

Linear-time prediction of proteome-scale microbial protein interactions

Protein–protein interactions (PPIs) underpin biological function, yet proteome-scale interaction prediction remains bottlenecked by the quadratic computational complexity of all-vs.-all pairwise comparisons. Here, we present FlashPPI, a contrastive learning framework, grounded in residue-level interactions, that enables linear-time prediction of physical protein interfaces across a microbial proteome. By leveraging a genomic language model that captures cross-protein coevolutionary signals from metagenomic sequences, FlashPPI aligns interacting partners in a shared latent space. We demonstrate a four-fold performance increase over existing sequence-based methods, while reducing proteome-wide screening time from days to minutes. Crucially, FlashPPI achieves comparable screening performance to state-of-the-art structure-folding models at a fraction of the computational cost. Finally, we integrate FlashPPI into an interactive web platform that combines predicted networks with functional annotations and genomic context, making proteome-wide network analysis rapid and accessible for microbial discovery.

Discovery of BIRC3 gene variants in Crohn’s disease yields a druggable pathway

Researchers from The Hospital for Sick Children (SickKids) in Toronto have found a previously unknown genetic cause of Crohn’s disease and uncovered how those changes trigger inflammation through a key immune pathway. The findings, published in Gastroenterology and involving teams from eight countries, will guide more precise treatments and improve the ability to match patients to therapies based on their unique biology.

“We’ve brought together genetics, RNA sequencing, proteomics and more to try for the first time to map the complete disease pathway, and it’s turned into a remarkable precision medicine story,” says lead author Dr. Aleixo Muise, senior scientist in the Cell & Systems Biology program, staff gastroenterologist and co-director of the Inflammatory Bowel Disease (IBD) Centre at SickKids.

“In our SickKids clinic, we want to find the right drug for each person based on their body’s unique signature. That’s why this paper is so exciting: We have pinpointed a druggable pathway.”

MXene-polymer composite enables printed, eco-friendly device for energy harvesting and motion-sensing

Researchers at Boise State University have developed a novel, environmentally friendly triboelectric nanogenerator (TENG) that is fully printed and capable of harvesting biomechanical and environmental energy while also functioning as a real-time motion sensor. The innovation leverages a composite of Poly (vinyl butyral-co-vinyl alcohol-co-vinyl acetate) (PVBVA) and MXene (Ti3C2Tx) nanosheets, offering a sustainable alternative to conventional TENGs that often rely on fluorinated polymers and complex fabrication.

TENGs are innovative energy-harvesting devices that convert mechanical energy into electricity using the triboelectric effect. They were invented by Prof. Zhong Lin Wang of the Georgia Institute of Technology and generate power through contact and motion between materials, making them ideal for applications like wearable electronics, IoT sensors, and self-powered devices.

This work, published in the journal Nano Energy and led by Ph.D. student Ajay Pratap under the supervision of Prof. David Estrada of the Micron School of Materials Science and Engineering at Boise State University, showcases how additive manufacturing can produce high-performance, skin-compatible, and flexible devices for real-world applications in energy harvesting, wearables electronics, and human-machine interaction.

3 Age-Reversal Therapies Being Tested Right Now

Most people still think Longevity Escape Velocity is a distant future. But what if some of the technologies that could make it possible are already being tested right now?

In this video, we look at three emerging longevity therapies: partial epigenetic reprogramming, senescent-cell removal, and stem-cell based repair. Some are already in human trials, while others are still early and experimental, but together they show how medicine may begin shifting from treating age-related disease to repairing parts of aging itself.

Scientists Visualize the Complex, Dynamic World Inside a Human Cell

The interactive image was created for Cell Signaling Technology, Inc., and was inspired by the work of David Goodsell, a professor of computational biology at Scripps Research Institute, who is widely recognized for his vibrant watercolor paintings of cells and viruses. Alongside some artistic interpretation, portions of the image were digitally rendered using datasets gathered through scientific methods.

“This 3D rendering of a eukaryotic cell is modeled using X-ray, nuclear magnetic resonance (NMR), and cryo-electron microscopy datasets for all of its molecular actors,” explains McGill. “It is an attempt to recapitulate the myriad pathways involved in signal transduction, protein synthesis, endocytosis, vesicular transport, cell-cell adhesion, apoptosis, and other processes.”

Although some online are calling it “the most detailed image of a human cell ever captured” Evan Ingersoll and Gael McGill emphasize that it’s really an educational tool. Elements of the cell have been simplified, and in some cases “squashed together,” to help viewers better understand what happens inside it.

Scientists Finally Figured Out Why 90% of Humans Are Right-Handed

Not to toot my own horn or anything, but I can extend my empathy beyond myself just enough to imagine someone else’s perspective, fully knowing I’ll never completely understand the texture of their experience. But as a right-handed person, I will never, ever be able to do that for left-handed people. There’s just something in my brain preventing me from understanding how someone can navigate the world primarily using the hand I mostly rely on to accidentally test the sharpness of kitchen knives.

So naturally, it always made sense to me that around 90 percent of humans are right-handed. What never made sense was why. According to new research published in PLOS Biology, we may have finally figured it out: humans became overwhelmingly right-handed because we started walking upright and developed massive brains.

Researchers from the University of Oxford analyzed more than 2,000 primates across 41 species, comparing handedness with factors like social behavior, diet, body size, and movement. Nothing fully explained humanity’s innate steadfast dedication to right-handedness until researchers started factoring in brain size and the ratio between leg and arm length.

AI Will Eat Social Media Alive

Social media is being consumed by AI from the inside out.

Over half of all new written content online is now AI-generated, and more than half of all internet traffic is bots.

Facebook’s most-viewed images are AI slop, YouTube recommends brainrot to new users, and global content farms churn out synthetic shock content for pennies.

The platforms aren’t fighting it because engagement is engagement, whether it comes from humans or machines.

Mark Zuckerberg is calling AI the \.
