Brain scans reveal a possible cause of long COVID fatigue and brain fog

Summary

Brain scans suggest that long COVID may affect dopamine-releasing neurons, offering a possible explanation for persistent fatigue, low motivation, slowed movement, and memory problems. The finding points toward treatments that target the brain's dopamine system.

The important advance is a plausible biological pathway linking long COVID to its cognitive and

Why it matters

A validated dopamine pathway could enable more targeted diagnosis and treatment for patients whose long COVID symptoms remain difficult to explain.

What kills Schrödinger’s cat? Gravity may not be the answer

Summary

Researchers tested a theory that gravity-driven fluctuations in spacetime cause quantum superpositions to collapse and produce faint radiation. A 62-day search with a shielded detector beneath Italy’s Gran Sasso mountain found no predicted signal.

The null result weakens a prominent gravity-based explanation for why quantum behavior disappears at everyday

Why it matters

A leading explanation for the boundary between quantum and classical physics has lost experimental support.

Stem cells reverse stroke damage and restore movement in mice

Summary

Stem cell transplants helped mice regenerate brain tissue damaged by stroke, including new neurons, and restored lost motor function. The treatment also improved blood vessels, reduced inflammation, and repaired the blood-brain barrier.

The decisive limitation is that the result has only been shown in mice, so it

Why it matters

A successful human version could expand stroke treatment from rehabilitation and prevention to biological repair.

Scientists discover first new penguin species in more than 100 years

Summary

Genetic analysis identified a previously unrecognized gentoo penguin species on the Kerguelen Islands and showed that gentoos comprise four distinct species. The study also warns that warming oceans could leave several island populations with little suitable habitat by 2050.

The taxonomic finding changes how scientists measure gentoo penguin diversity and risk, because populations once

Why it matters

Recognizing distinct species can trigger more precise conservation plans, but climate pressure may outpace efforts to protect them.

The Steam Deck Is Being Used to Test Mars Rovers

Summary

Scientists at Airbus in the UK are using Valve's Steam Deck to test the ExoMars rover. The gaming handheld is serving as a practical tool in rover development despite being designed for consumer entertainment.

The key shift is that a low-cost, widely available gaming device has entered a professional

Why it matters

Off-the-shelf hardware could make planetary robotics testing cheaper and more flexible.

Black holes of every size follow the same surprising rule

Summary

Observations suggest that black holes ranging from stellar to supermassive launch jets when their feeding rate falls to roughly 2% of the Eddington limit. Supermassive black holes can reach this state after tearing apart a star and later restarting their jets.

The shared threshold links black holes across vastly different scales and supports a common mechanism

Why it matters

A universal jet trigger could unify black-hole physics that has usually been studied in separate size regimes.

A new process turns plastic waste into gasoline and diesel fuel

Summary

Oak Ridge National Laboratory researchers used inexpensive aluminum-based molten salts to break polyethylene into smaller hydrocarbons under relatively mild conditions. The process produced a mixture containing about 60% gasoline-range fuel, along with diesel-like products.

The advance makes chemical recycling of a common plastic more practical by replacing harsher conditions

Why it matters

The process could turn difficult-to-recycle polyethylene into usable products, but it is not a substitute for reducing plastic production.

Scientists create a needle-thin brain implant that can do three jobs at once

Summary

Researchers developed a flexible, needle-thin implant that can record neural activity, deliver drugs, and stimulate several brain regions through one fiber. Tests in mice suggest the device could support more precise brain research and eventually neurological treatments.

The device combines functions that typically require separate hardware, potentially reducing the damage and complexity

Why it matters

A single minimally invasive implant could improve both experimental neuroscience and future therapies for disorders such as epilepsy.

NASA just powered up Roman’s massive 300-megapixel camera

Summary

NASA has activated the Nancy Grace Roman Space Telescope's 300-megapixel infrared camera, which will survey large regions of the universe at Hubble-like sharpness. Its coronagraph, designed to study exoplanets, is also operating as expected, with science operations planned for 2027.

Roman has cleared a major hardware test, bringing its wide-field surveys and direct exoplanet imaging

Why it matters

Roman's camera will give astronomers a much larger and sharper map of the infrared universe.

Amazon study reveals the best strategies for protecting biodiversity and carbon

Summary

A large Amazon analysis found that protecting existing forests from fire and logging produced the strongest biodiversity gains and nearly matched deforestation prevention for carbon storage. Restoration helped in heavily cleared areas but cost more and was less effective when used alone.

The evidence favors preventing forest damage before attempting broad restoration, especially where conservation funds are

Why it matters

Conservation budgets can protect more species and carbon by defending intact Amazon forests before they are damaged.

Stanford scientists discover the human brain may actually be two separate organs

Summary

Researchers found that the human brain develops from two distinct cellular systems, suggesting that evolution combined ancient nervous systems with different functions. The work also enabled them to grow human hindbrain neurons in the laboratory for disease research.

The developmental finding revises how scientists may understand the brain's organization and provides a way

Why it matters

A new developmental model could reveal why brainstem disorders arise and improve disease-specific testing.

Why is trust in science important?

Summary

STAT's Alex Hogan speaks with trust-in-science reporter Nicholas Florko about why public confidence in scientific institutions matters.

Trust shapes whether people accept scientific findings, follow health guidance, and support research institutions. As

Why it matters

Scientific knowledge only changes behavior and policy when people believe the institutions producing it.
