A researcher from the University of Tokyo and a U.S.-based structural engineer developed a new computational form-finding method that could change how architects and engineers design lightweight and free-form structures covering large spaces. The technique specifically helps create gridshells, thin, curved surfaces whose members form a networked grid. The method makes use of NURBS surfaces, a widely used surface representation format in computer-aided design (CAD). It also drastically reduces computation cost — a task that previously took 90 hours on a high-end GPU completes in about 90 minutes on a standard CPU.

Cedars-Sinai scientists have created a new experimental drug called TY1 that helps the body repair damaged DNA and restore injured tissue. The discovery came from studying tiny molecular messages released by heart cells that naturally support healing after injury. By identifying and recreating the most powerful of these messages, the team developed a synthetic RNA molecule that boosts the body’s DNA-repair system, reduces scarring, and may improve recovery after heart attacks and other diseases.

A large study found that people with impaired kidneys tend to have higher Alzheimer’s biomarkers, yet they don’t face a higher overall risk of dementia. For those who already have elevated biomarkers, kidney problems may speed up when symptoms appear. The findings show that kidney health can change how Alzheimer’s blood tests are read. Doctors may need to consider both organs to get a clearer picture.

A low-dose mix of zinc, serine, and branched-chain amino acids boosted neural function and social behavior in autism mouse models.

Researchers found that people with anxiety disorders consistently show lower choline levels in key brain regions that regulate thinking and emotions. This biochemical difference may help explain why the brain reacts more intensely to stress in anxiety conditions. Scientists believe nutrition could play a role in restoring balance, though more research is needed. Many Americans already fall short of recommended choline intake, making diet a potential area of interest.

Researchers studying people with major psychiatric disorders found that drinking up to four cups of coffee a day is associated with longer telomeres. This suggests a potential slowing of biological aging by about five years. However, drinking five or more cups showed no benefit and may even contribute to cellular damage. Coffee’s antioxidant and anti-inflammatory properties may help explain the effect.

This year’s ozone hole over Antarctica ranked among the smallest since the early 1990s, reflecting steady progress from decades of global action under the Montreal Protocol. Declining chlorine levels and warmer stratospheric temperatures helped limit ozone destruction. Scientists say the layer remains on track to recover later this century.

Experiments reveal that pond frogs can eat highly venomous hornets without suffering noticeable damage, even after repeated stings. Most frogs successfully consumed hornets, including the notorious Asian giant hornet. This unusual resilience suggests that frogs may have evolved mechanisms to block the effects of venom. Their resistance could help scientists uncover new insights into pain and toxin tolerance.

Earth’s orbit is getting crowded with broken satellites and leftover rocket parts. Researchers say the solution is to build spacecraft that can be repaired, reused, or recycled instead of abandoned. They also want new tools to collect old debris and new data systems that help prevent collisions. The goal is to make space exploration cleaner and more sustainable.

Researchers recreated conditions from billions of years ago and found that Earth’s young atmosphere could make key molecules linked to life. These sulfur-rich compounds, including certain amino acids, may have formed naturally in the sky. The results suggest early Earth wasn’t starting from zero but may have already been stocked with essential ingredients.

Ant pupae that are fatally sick don’t hide their condition; instead, they release a special scent that warns the rest of the colony. This signal prompts worker ants to open the pupae’s cocoons and disinfect them with formic acid, stopping the infection before it can spread. Although the treatment kills the sick pupa, it protects the colony and helps ensure its long-term survival. Researchers found that only pupae too sick to recover send this scent, showing just how finely tuned the colony’s early-warning system is.

College life creates a perfect storm for overeating, as students consume more calories when surrounded by friends, eating in dining halls, or following unstructured schedules. A four-week study using a mobile app revealed that students often underestimate how much they eat, especially in social or formal dining settings. Emotional influences, gender differences, and environmental cues all contribute to this subtle but consistent rise in intake.

Researchers have discovered a new way to grow graphene that deliberately adds structural defects to enhance its usefulness in electronics, sensors, catalysts, and more.

A surprisingly mature spiral galaxy named Alaknanda has been spotted just 1.5 billion years after the Big Bang—far earlier than astronomers believed such well-structured galaxies could form. With sweeping spiral arms, rapid star formation, and an orderly disk resembling our Milky Way, it defies long-held theories about how slowly galaxies should assemble. Thanks to JWST and gravitational lensing, researchers could examine the galaxy in remarkable detail, revealing that the early Universe was far more capable and dynamic than expected.

Ancient anaconda fossils show that the snakes became giants soon after emerging in Miocene South America. Their size has stayed stable for over 12 million years, even though other huge reptiles went extinct. Surprisingly, warmer periods didn’t make anacondas bigger—just more widespread. Today they remain large thanks to surviving patches of ideal wetland habitat.

Stanford researchers found that gas stoves expose Americans to surprisingly high levels of nitrogen dioxide—often matching or exceeding outdoor pollution. For millions, cooking alone pushes NO2 over long-term safety thresholds. Smaller homes, renters, and rural households face the highest concentrations. Cleaner cooking technologies could substantially reduce the risks.

Researchers have solved the decades-old mystery behind how a common pregnancy drug lowers blood pressure. It turns out the medication blocks a fast-acting “oxygen alarm” inside cells. That same alarm helps brain tumors survive, meaning the drug unexpectedly weakens them, too. The discovery could inspire better treatments for both preeclampsia and brain cancer.

Scientists have discovered that a single gene, GRIN2A, can directly cause mental illness—something previously thought to stem only from many genes acting together. People with certain variants of this gene often develop psychiatric symptoms much earlier than expected, sometimes in childhood instead of adulthood. Even more surprising, some individuals show only mental health symptoms, without the seizures or learning problems usually linked to GRIN2A.

Some white dwarfs in rapid binary orbits are far hotter and larger than theory predicts. Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and change their orbital behavior. This leads the stars to interact much sooner than expected, potentially triggering dramatic cosmic events. The new model may offer clues about the origins of type Ia supernovae.

Scientists found that combining oxytocin with an Alk5 inhibitor revitalized extremely old male mice, boosting their lifespan and strength. Female mice showed only short-term improvements, highlighting a major sex difference in aging biology.

Because the components are already clinically accessible, this approach could move toward human testing.

Archaeologists excavating the ancient Roman city of Gabii have uncovered a massive stone-lined basin that may represent one of Rome’s earliest monumental civic structures. Its central placement hints that early Romans were already experimenting with dramatic public spaces centuries before the iconic Forum took shape. The site’s remarkable preservation—made possible because Gabii was abandoned early—offers an unprecedented look at how Romans adapted Greek architectural ideas into powerful symbols of politics, ritual, and identity.

Scientists discovered that the first 100 base pairs of human genes are unusually prone to mutations, especially during the earliest stages of embryonic development. These mosaic mutations often go undetected yet can still be passed on and cause disease. Large-scale genome analyses show that genes tied to cancer and brain function are particularly affected, with natural selection filtering out harmful variants. The study highlights the need to adjust genetic models and rethink how researchers identify disease-relevant mutations.

Researchers discovered that 168 common chemicals can disrupt the growth of beneficial gut bacteria, with some also promoting antibiotic resistance. Many of these substances—found in food, water, and household items—weren’t previously suspected of affecting living organisms. A new machine learning model now predicts which chemicals may harm the microbiome. The findings suggest safety testing must expand to consider gut health.

Nitrous oxide may offer quick, short-term relief for people with major depression, especially those who haven’t responded to standard medications. The meta-analysis found rapid improvements after a single dose and more sustained benefits after repeated treatments. Side effects were generally mild and brief, though researchers stress the need for larger, longer-term studies.

Scientists found that adult bristleworm eyes grow continuously thanks to a rim of neural stem cells similar to those in vertebrate eyes. This growth is surprisingly regulated by environmental light via a vertebrate-like c-opsin. The discovery reveals deep evolutionary parallels between distant species and raises questions about how light shapes nervous systems beyond vision. It hints at hidden complexity in creatures long assumed to be simple.

As the last Ice Age waned and the Holocene dawned, deep-ocean circulation around Antarctica underwent dramatic shifts that helped release long-stored carbon back into the atmosphere. Deep-sea sediments show that ancient Antarctic waters once trapped vast amounts of carbon, only to release it during two major warming pulses at the end of the Ice Age. Understanding these shifts helps scientists predict how modern Antarctic melt may accelerate future climate change.

Younger women are being diagnosed with breast cancer more often than screening guidelines anticipate. Many of these cancers are invasive and harder to treat, especially in those under 40. After analyzing 11 years of data, researchers found that this age group makes up a steady and significant share of diagnoses. The results support a stronger push for earlier risk evaluation.

A high-speed “zap-and-freeze” method is giving scientists their clearest view yet of how brain cells send messages.
