Einstein’s equations may explain the universe without dark energy
Mathematicians are raising a major challenge to one of modern cosmology’s most widely accepted explanations: the idea that dark energy is driving the accelerating expansion of the universe.
A study published in Proceedings of the Royal Society A presents mathematical findings that researchers at the University of California, Davis, say reveal a fundamental instability in the standard model of the expanding universe. Their calculations suggest that cosmic acceleration could emerge naturally from Einstein’s equations, potentially eliminating the need to invoke mysterious dark energy.
Light reshapes gelatin scaffolds to steer cell growth in three dimensions
Soft, flexible hydrogels have enabled significant advancements in engineering biological tissue by mimicking the natural scaffolding that provides structure and support to cells. Existing engineered hydrogels, however, fall short in a significant way. Unlike in nature, they do not have the dynamic ability to change their structure or support depending on what the biological tissue needs. The answer may rest in shining a light on the problem—literally, according to a team led by researchers at Yokohama National University.
The researchers found that precisely applying light to a gelatin-based hydrogel they developed allows them to accurately control the shape of the gel, which allowed them to direct the growth direction and shape of nearby cells. The team published their work, which they said could have implications for tissue growth in health and in disease, on Sept. 2 in ACS Biomaterials Science & Engineering.
“The ability to control the morphology of pre-encapsulated cells on demand is useful for mimicking tissues, such as blood vessels and nerves, which change their growth direction according to their environment,” said corresponding author Kazuhiro Iijima, an associate professor in the Faculty of Engineering at Yokohama National University.
How and when does AGI transform the economy?

“Smarter AI will increase productivity but real economic transformation hinges on agents learning to coordinate.”
Is AGI really going to transform the economy as fast as the benchmarks suggest? 🧠📈
A landmark essay from Google DeepMind (“The Economics of Intelligence”) offers a compelling reality check on why exponential AI benchmarks haven’t immediately translated into macroeconomic productivity gains.
Here are three key takeaways from the research:
An Overlooked Immune Cell Killed The Deadliest Form of Lung Cancer in Lab Tests
Small cell lung cancer (SCLC) is a particularly aggressive and deadly disease: fewer than 7 in 100 people survive it for five years.
One of the tricks SCLC uses to persist and to evade treatments is to hide itself from the immune system. Now, an international team of researchers has found a way of removing that disguise and making SCLC more vulnerable.
The crucial component of the new approach is a type of immune cell called gamma delta T cells.
Scientists discover that cranberry juice may help fight tooth decay
Cranberry juice may offer an unexpected benefit for your teeth. New research suggests that pure, unsweetened cranberry juice can slow the growth of dental plaque and reduce the production of acids that contribute to tooth decay.
Cranberries are a familiar part of holiday celebrations. They appear in sauces, salads, and cocktails, and even serve as colorful seasonal decorations. But beyond their tart flavor and festive appeal, these small red berries contain natural compounds that may support oral health.
IQM’s Cloud Users Now Access A Fully Entangled 54-qubit Chip
IQM achieves full-chip entanglement across all 54 qubits of its Emerald processor, delivering enhanced performance to cloud users.
Marine molecule may help combat ‘brain-eating’ amoeba
Primary amoebic meningoencephalitis (PAM), a parasitic disease that causes the rapid deterioration of brain tissue, is one of the most lethal infections known, with a fatality rate exceeding 97%. Caused by the free-living amoeba Naegleria fowleri (N. fowleri), the disease progresses with devastating speed, often leaving patients with only a few days to respond to treatment.
Now, researchers at the University of California San Diego have isolated a marine-derived compound that may provide a faster, more effective way to stop the parasite.
The study, published in Marine Drugs, was led by Debnath, Fenical and Hayley Fong, who completed this project as part of her doctoral research at UC San Diego.
Mathematical puzzle from 1904 takes physical form in gold-studded helium droplets
When identical charges repel each other but are confined to the surface of a sphere, they seek the arrangement with the lowest possible energy. The idea is simple, but the problem gets harder to solve with every charge added. The so-called Thomson problem dates back to the “plum-pudding” model of the atom, which Nobel laureate Joseph J. Thomson proposed in 1904. The atomic model has long been superseded, but the mathematical problem has endured.
In 1998, mathematician Stephen Smale listed it as Problem No. 7 among his 18 major mathematical challenges for the 21st century. Exact solutions still exist only for a few small systems. The question also matters well beyond mathematics—for example, for the structure of viruses, fullerenes and colloidal shells.
Prismatic batteries to supercharge US power grid with 17% more energy
The US power grid will get one gigawatt hour (GWh) of new batteries with higher energy density, better fire safety, and a 25-year life.
