Researchers have launched the first coordinated plan to protect microbial biodiversity, calling attention to the “invisible 99% of life” that drives essential Earth systems. The IUCN has formally recognized this effort through the creation of the Microbial Conservation Specialist Group. By developing new metrics, policies, and restoration tools, scientists aim to make microbial life a core part of global conservation action. The roadmap also outlines upcoming goals such as microbial hotspot maps and new microbe-based conservation solutions.

Researchers have recreated a miniature human bone marrow system that mirrors the real structure found inside our bones. The model includes the full mix of cells and signals needed for blood production and even maintains this process for weeks. It could transform how scientists study blood cancers and test new drugs. In the future, it may support more personalized treatment strategies.

New research shows that light’s magnetic field is far more influential than scientists once believed. The team found that this magnetic component significantly affects how light rotates as it passes through certain materials. Their work challenges a 180-year-old understanding of the Faraday Effect and opens pathways to new optical and magnetic technologies.

Operating a new device named the Fusion Z-pinch Experiment 3, or FuZE-3, Zap Energy has now achieved plasmas with electron pressures as high as 830 megapascals (MPa), or 1.6 gigapascals (GPa) total, comparable to the pressures found deep below Earth’s crust.

MIT engineers have created an ultrasonic device that rapidly frees water from materials designed to absorb moisture from the air. Instead of waiting hours for heat to evaporate the trapped water, the system uses high-frequency vibrations to release droplets in just minutes. It can be powered by a small solar cell and programmed to cycle continuously throughout the day. The breakthrough could help communities with limited access to fresh water.

Researchers found that hot tubs raise core body temperature more effectively than traditional or infrared saunas, leading to stronger boosts in blood flow and immune activity. Only hot-water immersion produced measurable changes in inflammatory markers. These effects can persist beyond the session, suggesting a sustained health benefit. For anyone unable or unwilling to exercise, heat therapy may offer a surprisingly effective option.

Researchers uncovered a powerful weakness in lung cancer by shutting down a protein that helps tumors survive stress. When this protein, FSP1, was blocked, lung tumors in mice shrank dramatically, with many cancer cells essentially triggering their own self-destruct mode. The work points to a fresh strategy for targeting stubborn lung cancers.

Scientists confirmed that West Coast transient killer whales actually form two separate groups split between inner and outer coastal habitats. Inner-coast whales hunt smaller prey in shallow, maze-like waterways, while outer-coast orcas pursue large marine mammals in deep offshore canyons. The groups rarely interact, despite sharing a broad range along the Pacific Coast. Their contrasting lifestyles highlight the need for distinct conservation strategies.

Researchers created a dissolvable microneedle patch that delivers IL-4 directly to damaged heart tissue, jump-starting repair after a heart attack. The targeted approach shifts immune cells into a healing mode while improving communication between heart muscle and blood vessel cells. It avoids the systemic risks of IL-4 injections and shows promise for future minimally invasive treatment.

New climate modeling shows that heatwaves will keep getting hotter, longer, and more frequent for centuries—even after the world hits net-zero emissions. Delays of just a few years dramatically increase the likelihood of extreme, once-rare heat disasters, especially for countries near the equator. The research reveals that even reaching net zero by mid-century won't reverse the trend, and some regions will continue to see worsening heatwaves for a thousand years.

Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New modeling suggests that slow leakage of elements from Earth’s core into the mantle prevented the planet from developing strong chemical layers after its primordial magma-ocean era.

A nationwide analysis has uncovered how sprawling fossil fuel infrastructure sits surprisingly close to millions of American homes. The research shows that 46.6 million people live within about a mile of wells, refineries, pipelines, storage sites, or transport facilities. Many of these locations release pollutants that may affect nearby communities, yet mid-supply-chain sites have rarely been studied. The findings reveal major gaps in understanding how this hidden network affects health.

Experts say the ocean could help absorb carbon dioxide, but today’s technologies are too uncertain to be scaled up safely. New findings released during COP30 highlight the risks of rushing into marine carbon removal without proper monitoring and verification. With the 1.5°C threshold approaching, researchers stress that emissions cuts must remain the top priority. Ocean-based methods may play a role later, but they need careful oversight first.

Researchers discovered a way to keep T cells from wearing out during the fight against cancer, and the approach could make immune-based treatments far more powerful. They found that tumors use a particular molecular signal to weaken T cells, and that interrupting this signal helps the cells stay active.

Researchers created scalable quantum circuits capable of simulating fundamental nuclear physics on more than 100 qubits. These circuits efficiently prepare complex initial states that classical computers cannot handle. The achievement demonstrates a new path toward simulating particle collisions and extreme forms of matter. It may ultimately illuminate long-standing cosmic mysteries.

Researchers have found a way to make “dark excitons”—normally invisible quantum states of light—shine dramatically brighter by trapping them inside a tiny gold-nanotube optical cavity. This breakthrough boosts their emission 300,000-fold and allows scientists to switch and tune them with unprecedented precision. The work unlocks new possibilities for ultrafast photonics, on-chip quantum communication, and exploring previously unreachable quantum states in 2D materials.

Chameleons’ extraordinary ability to move their eyes independently stems from a previously overlooked anatomical marvel: long, tightly coiled optic nerves hidden behind their bulging eyes. Modern CT imaging finally revealed this structure, which centuries of dissections and even the scrutiny of figures like Aristotle and Newton failed to capture. The coils give the eyes extra slack, enabling nearly 360-degree scanning without neck mobility.

Massive Sargassum blooms sweeping across the Caribbean and Atlantic are fueled by a powerful nutrient partnership: phosphorus pulled to the surface by equatorial upwelling and nitrogen supplied by cyanobacteria living directly on the drifting algae. Coral cores reveal that this nutrient engine has intensified over the past decade, perfectly matching surges in Sargassum growth since 2011. By ruling out older theories involving Saharan dust and river runoff, researchers uncovered a climate-driven process that shapes when and where these colossal seaweed mats form.

Scientists have developed a new molecule that breaks down beta-amyloid plaques by binding to excess copper in the brain. The treatment restored memory and reduced inflammation in rats, while also proving non-toxic and able to cross the blood–brain barrier. Because it’s far simpler and potentially cheaper than existing drugs, researchers are now pursuing partnerships to begin human trials.

Researchers discovered that chronic inflammation fundamentally remodels the bone marrow, allowing mutated stem cell clones to quietly gain dominance with age. Reprogrammed stromal cells and interferon-responsive T cells create a self-sustaining inflammatory loop that weakens blood production. Surprisingly, the mutant cells themselves may not be the main instigators.
