Naturally occurring molecule can stop Alzheimer's-linked fibrils from forming Protein droplets serve important biological functions within cells, but in neurodegenerative diseases like Alzheimer's, these liquid-like droplets can form solid-like clumps known as fibrils.

L-arginine, a naturally occurring metabolite, has been shown to stabilize protein droplets in cells and inhibit their conversion into amyloid fibrils linked to Alzheimer's disease. doi.org/hbxsgm

RFK Jr accused of ‘dangerous conspiracy theories’ at heated budget hearing Trump ally grilled by lawmakers over ‘terrible decisions’ on vaccines, public health and funding cuts to key programs

RFK Jr. was exposed in last week’s hearing for exactly what he is: a conspiracy theorist with no medical expertise making dangerous decisions for our health. He must go. Tell your Rep to co-sponsor the articles of impeachment at this link: zurl.co/5ge8z

How a tiny circle of repeat offenders poisoned 100s of gold-standard medical trials for over a decade Randomized Controlled Trials (RCTs) are the gold standard of medical research as random assignment approach helps eliminate bias and yields the most reliable evidence on whether a treatment truly works.

A small group of highly cited authors accounts for a disproportionate share of retracted randomized clinical trials, allowing unreliable findings to persist and influence medical guidelines for years. doi.org/hbxj5b

RFK Jr.'s hearing today highlighted his countless conspiracy driven, scientifically unfounded, and even racist rhetoric that drives his decisions on American health. He must go. Visit zurl.co/Iy3bo to tell your Rep to co-sponsor the articles of impeachment against RFK Jr.

Navigating the past with ancient stone compass needles Magnetic rocks with iron oxide concentrations act as natural chroniclers of Earth's past continental movements. Using small samples of rocks, scientists can isolate magnetic grains that were frozen in orientation as the rock solidified.

Magnetic microscopy enables high-resolution mapping of ancient magnetic fields in rocks, improving the precision of Earth's magnetic history reconstructions while highlighting challenges in detecting stable, tiny grains. doi.org/hbxf64

The cold virus 'hides' and multiplies in the tonsils and adenoids, even in people without symptoms A study conducted at the University of São Paulo (USP) in Brazil reveals that tissues such as the tonsils and adenoids can serve as hiding places for the rhinovirus, which causes the common cold and is responsible for most respiratory infections worldwide.

Rhinovirus, which causes the common cold, can persist and replicate in tonsils and adenoids—even in asymptomatic individuals—potentially enabling silent transmission. doi.org/hbxf7c

Industrial chemical leaks could push ozone layer recovery back by 7 years The recovery of the ozone layer in Earth's stratosphere could be delayed by several years, according to an international study led by Swiss research institution Empa which included contributions from University of Bristol researchers.

Persistent leaks of industrial feedstock chemicals are delaying ozone layer recovery by up to seven years and contributing significantly to greenhouse gas emissions, highlighting a critical regulatory gap. doi.org/hbxf95

Inside a jubilant DC conference where ‘the climate deniers are in charge now’ Trump’s EPA chief Lee Zeldin’s presence shows how much influence climate deniers now have, experts say

We’re in danger. Climate deniers are no longer on the fringe. They are shaping U.S. policy, protecting polluters, and pushing us deeper into crisis. Stand Up for Science with us: zurl.co/NUlsN

What raises vaccination rates most? Access, community outreach and incentives lead the list Extending vaccination opportunities, involving community members alongside health care professionals in communicating about vaccines, and providing financial incentives are among the most effective ways to increase vaccine uptake, finds an analysis of international trial evidence published by The BMJ.

Extending vaccination access, engaging community members in outreach, and offering financial incentives are among the most effective strategies to increase vaccine uptake across populations.

This infographic, "MOFs: What are they good for?", defines Metal-Organic Frameworks as crystalline "molecular sponges" made of metal ions and organic linkers. It details four commercial applications: carbon capture using zinc-based CALF-20, safer gas storage for semiconductor manufacturing, harvesting atmospheric water in deserts using aluminum-based MOF-303, and the detoxification of chemical warfare agents. It notes that MOF research won the 2025 Nobel Prize in Chemistry.

The United States Can Still Reach the Stars. President Trump’s New Budget Can't. NASA is attempting to return humans to the moon at the same time that its budget is being slashed. The military, meanwhile, gets a huge increase.

"Watching the Artemis launch, I felt hope for US science for the first time in a while. The president’s budget request brought me back down to Earth."

The number zero as we use it today — as an actual integer with arithmetic rules — was first clearly defined in the 7ᵗʰ century CE by Indian mathematician Brahmagupta; before that, symbols for “nothing” existed, but not with full numeric rules.
