Why multiple sclerosis slowly steals balance and movement13:42 Many people with multiple sclerosis struggle with balance and coordination, and this study uncovers a hidden reason why. Researchers found that inflammation in the brain disrupts the energy supply of vital movement-controlling neurons. As their mitochondria fail, these cells weaken and eventually die, worsening motor problems over time. Protecting brain energy systems could open the door to slowi… Tiny 3D-printed light cages could unlock the quantum internet13:42 A new chip-based quantum memory uses nanoprinted “light cages” to trap light inside atomic vapor, enabling fast, reliable storage of quantum information. The structures can be fabricated with extreme precision and filled with atoms in days instead of months. Multiple memories can operate side by side on a single chip, all performing nearly identically. The result is a powerful, scalable building … A simple drug pair may succeed where liver fibrosis treatments failed13:42 Scientists have found that combining silybin with carvedilol works far better against liver fibrosis than either drug alone. The duo targets the root drivers of liver scarring, sharply reducing collagen buildup and liver damage in experimental models. Importantly, both drugs are already approved and commonly prescribed. That makes this discovery especially promising for rapid clinical translation. Earth’s toughest microbes could help humans live on Mars13:42 Mars looks familiar from afar, but surviving there means creating a protective oasis in a hostile world. Instead of shipping construction materials from Earth, researchers are exploring how to use Martian soil as the raw ingredient. Two tough microbes could work together to bind dust into a concrete-like material and even help generate oxygen. The vision: 3D-print habitats using local resources, … Scientists find a safer way for opioids to relieve pain13:42 Researchers at USF Health have discovered a new way opioid receptors can work that may lead to safer pain medications. Their findings show that certain experimental compounds can amplify pain relief without intensifying dangerous side effects like suppressed breathing. This research offers a fresh blueprint for designing opioids that last longer, work better, and pose fewer risks. It also opens d… Scientists create robots smaller than a grain of salt that can think13:42 Researchers have created microscopic robots so small they’re barely visible, yet smart enough to sense, decide, and move completely on their own. Powered by light and equipped with tiny computers, the robots swim by manipulating electric fields rather than using moving parts. They can detect temperature changes, follow programmed paths, and even work together in groups. The breakthrough marks the… A NASA satellite caught a giant tsunami doing something scientists didn’t expect6:24 When a huge earthquake struck near Kamchatka, the SWOT satellite captured an unprecedented, high-resolution view of the resulting tsunami as it crossed the Pacific. The data revealed the waves were far more complex and scattered than scientists expected, overturning the idea that large tsunamis travel as a single, stable wave. Ocean sensors confirmed the quake’s rupture was longer than earlier mo… Scientists discover “migrions,” a viral shortcut that supercharges infection6:24 Scientists have uncovered a surprising viral shortcut that turns moving cells into delivery vehicles for infection. Instead of spreading one virus at a time, infected cells bundle viral material into large structures called Migrions and pass them directly to new cells. This collective delivery jump-starts viral replication and boosts disease severity. The finding reveals a migration-based route o… Flu drug once blamed for seizures in kids gets a surprising reversal6:24 A long-running debate over Tamiflu’s safety in children may finally be settled. Researchers found that influenza, not the antiviral medication, was linked to serious neuropsychiatric events like seizures and hallucinations. Even more striking, kids treated with Tamiflu had about half the risk of these events compared to untreated children with the flu. The results suggest the drug may be protecti… Nearly all women in STEM secretly feel like impostors6:24 Nearly all women in STEM graduate programs report feeling like impostors, despite strong evidence of success. This mindset leads many to dismiss their achievements as luck and fear being “found out.” Research links impostorism to worse mental health, higher burnout, and increased thoughts of dropping out. Supportive environments and shifting beliefs about intelligence may help break the cycle. Think you make 200 food choices a day? Think again6:24 The idea that we make over 200 unconscious food choices a day has been repeated for years, but new research shows the number is more illusion than insight. The famous figure comes from a counting method that unintentionally exaggerates how many decisions people really make. Researchers warn that framing eating as mostly “mindless” can undermine confidence and self-control. A more realistic view f… The secret to human intelligence? It might be in our gut0:49 New research shows gut bacteria can directly influence how the brain develops and functions. When scientists transferred microbes from different primates into mice, the animals’ brains began to resemble those of the original host species. Microbes from large-brained primates boosted brain energy and learning pathways, while others triggered very different patterns. The results suggest gut microbe… Scientists uncover a hidden switch that helps cancer cells thrive0:49 A protein once thought to simply help cancer cells avoid death turns out to do much more. MCL1 actively drives cancer metabolism by controlling the powerful mTOR growth pathway, tying survival and energy use together. This insight explains why MCL1-targeting drugs can be effective—but also why they sometimes damage the heart. Researchers have now identified a way to reduce that risk, potentially … A Greenland glacier is cracking open in real time23:06 A meltwater lake that formed in the mid-1990s on Greenland’s 79°N Glacier has been draining in sudden, dramatic bursts through cracks and vertical ice shafts. These events have accelerated in recent years, creating strange triangular fracture patterns and flooding the glacier’s base with water in just hours. Some drainages even pushed the ice upward from below, like a blister forming under the gl… Everyday chemicals are quietly damaging beneficial gut bacteria5.ledna A large study has revealed that dozens of widely used chemicals can damage beneficial gut bacteria. Many of these substances, found in pesticides and everyday industrial products, were never thought to affect living organisms at all. When gut bacteria are stressed by these chemicals, some may also become resistant to antibiotics. The research raises new questions about how chemical exposure could… |
