Scientists at Rutgers and collaborators have traced the invisible dark matter scaffolding of the universe using over 100,000 Lyman-alpha emitting galaxies. By studying how these galaxies clustered across three eras shortly after the Big Bang, they mapped dark matter concentrations, uncovering cosmic “fingerprints” that reveal how galaxies grow and evolve.

Addiction often isn’t about chasing pleasure—it’s about escaping pain. Researchers at Scripps Research have discovered that a tiny brain region called the paraventricular nucleus of the thalamus (PVT) becomes hyperactive when animals learn that alcohol eases the agony of withdrawal. This circuit helps explain why people relapse: their brains learn that alcohol brings relief from stress and anxiety. Read more

Ohio State researchers have discovered that exhausted T cells collapse under the weight of misfolded proteins, activating a destructive stress response called TexPSR. Unlike normal stress systems, TexPSR accelerates protein production, flooding the cells with toxic buildup. Blocking it restored T-cell function and improved cancer immunotherapy. Read more

When cancer cells are physically squeezed, they mount an instant, high-energy defense by rushing mitochondria to the cell nucleus, unleashing a surge of ATP that fuels DNA repair and survival. This newly discovered mechanism, visualized in real time with advanced microscopy, shows mitochondria acting like emergency first responders rather than static power plants. The structures, called NAMs, were also identified in patient tumor biopsies, suggesting real-world relevance to cancer’s spread. Read more

Flu detection could soon be as simple as chewing gum. Scientists have created a molecular sensor that releases a thyme-like flavor when it encounters influenza, offering a low-tech, taste-based alternative to nasal swabs. Unlike current tests that are slow, costly, or miss early infections, this method could catch the flu before symptoms appear. Read more

An international team has confirmed that large quantum systems really do obey quantum mechanics. Using Bell’s test across 73 qubits, they proved the presence of genuine quantum correlations that can’t be explained classically. Their results show quantum computers are not just bigger, but more authentically quantum. This opens the door to more secure communication and stronger quantum algorithms. Read more

Kobe University researchers found that orchids rely on wood-decaying fungi to germinate, feeding on the carbon from rotting logs. Their seedlings only grow near deadwood, forming precise fungal partnerships that mirror those seen in adult orchids with coral-like roots. This discovery highlights a hidden carbon pathway in forest ecosystems and explains the evolution of fully fungus-dependent orchid species. Read more
