Abu Dhabi, UAE, June 30, 2025: A team of researchers at NYU Abu Dhabi has uncovered a key mechanism that helps shape how our brains are wired, and what can happen when that process is disrupted.
In a new study published in Cell Reports, the RNA-MIND Lab at NYU Abu Dhabi, led by Professor of Biology Dan Ohtan Wang, with Research Associate Belal Shohayeb, reveals how a small molecular mark on messenger RNA, called m6A methylation, regulates the production of essential proteins inside growing neurons. This process plays a critical role in the development of axons, the long extensions that neurons use to connect and communicate with each other.
The study shows that this molecular mark controls the production of a protein called Adenomatous Polyposis Coli (APC), which helps organize the internal structure of nerve cells and is needed to locally produce β-actin, a key building block of cytoskeleton to support axon growth. Importantly, the team also found that genetic mutations linked to autism and schizophrenia can interfere with this process, potentially affecting how the brain develops.
“This research connects a global process, how proteins are made across the cell, with highly local effects in neurons that guide brain development,” said Ohtan Wang. “We’re learning that when these finely tuned systems break down, the impact can be seen in conditions like autism and schizophrenia. Understanding these molecular details could open the door to new ways of thinking about treatment and early intervention.”
As the brain forms, neurons must grow, connect, and communicate in precise ways. This research sheds light on the inner workings of that process and deepens our understanding of how even the smallest molecular changes can have far-reaching effects.
The paper, "m6A RNA methylation-mediated control of global APC expression is required for local translation of β-actin and axon development," is now available online in Cell Reports.

June 30, 2025 -- Inflammation, long considered a hallmark of aging, may not be a universal human experience, according to a new study from Columbia University Mailman School of Public Health. The research suggests that "inflammaging"—chronic, low-grade inflammation associated with aging—appears to be a byproduct of industrialized lifestyles and varies significantly across global populations. The findings are published in Nature Aging.
Researchers analyzed data from four populations: two industrialized ...

With a new $11 million federal grant, the University of Oregon will create a national center for children’s mental health, putting the university at the forefront of national prevention efforts to improve the mental health and well-being of adolescents.
The center will be housed in the UO’s Prevention Science Institute. It will be funded over the next five years by the National Institute of Mental Health.
“This center will build on the strong work the UO’s Prevention Science Institute has done over decades in the area of school-based mental health prevention, bringing ...

Caroline King didn’t expect to get involved in research when she arrived at The University of Texas at Arlington. But after joining the Honors College and taking a job with the Center for Rural Health and Nursing, she found herself diving into a literature review on midwifery in rural Texas.
Two and a half years later, King is a published author in the Online Journal of Rural Nursing and Health Care. While publication is a milestone for any academic, it’s a rare achievement for an undergraduate.

TikTok is one of the fastest-growing and most popular social media platforms in the world – especially among college-age individuals. In the United States alone, there are over 136 million TikTok users aged 18 and older, with approximately 45 million falling within the college-age demographic. And college students aren’t just using the platform to watch viral videos. They’re also turning to it as a source of information, with around 40% of Americans using TikTok as a search engine.
While the ...

PITTSBURGH, June 30, 2025—For the first time, the extreme variability in dengue fever has been linked to a biological mechanism, potentially opening doors to new treatments and vaccines for the most common mosquito-borne disease worldwide. The study was published today in Proceedings of the National Academy of Sciences (PNAS) by researchers from the University of Pittsburgh, UPMC and Instituto Aggeu Magalhães in Brazil.
Cases of dengue fever, commonly known as “breakbone fever” for the excruciating joint pain that is the hallmark of the disease, have ...

Using whole genome sequencing and cutting-edge analyses researchers at Stockholm University have uncovered the surprising evolutionary history of the Norwegian lemming (Lemmus lemmus), revealing it to be one of the most recently evolved mammal species. The results published in Proceedings of the National Academy of Sciences (PNAS), reveal that the Norwegian lemming is a distinct species that split from its closest relative, the Western Siberian lemming, approximately 35,000 years ago — just before the peak of the last Ice Age.

Going to bed earlier than usual may help to optimise physical activity the following day, Monash University-led research has found.
Published in Proceedings of the National Academy of Sciences (PNAS), the study examined whether sleep duration and sleep timing were associated with the duration of moderate-to-vigorous and overall physical activity the following day.
In the primary study, almost 20,000 participants wore a validated biometric device (WHOOP) for one year, resulting in almost six million nights of data. Objective sleep and physical activity metrics were derived from the wrist-worn device.
The study examined how both typical ...

Southern Ocean saltier, hotter and losing ice fast as decades-long trend unexpectedly reverses
Researchers have discovered a dramatic and unexpected shift in the Southern Ocean, with surface water salinity rising and sea ice in steep decline.
Since 2015, Antarctica has lost sea ice equal to the size of Greenland — the largest environmental shift seen anywhere on Earth in the last decades. The Southern Ocean is also getting saltier, and this unexpected change is making the problem worse.
For decades, the ocean’s surface freshened (becoming less salty), helping sea ice grow. Now, scientists ...

When we think of fossils, giant prehistoric creatures like dinosaurs may come to mind. But the fossil record also holds the remains of smaller organisms, such as fish and corals, that tell us about our oceans’ past.
Scientists at the Smithsonian Tropical Research Institute (STRI) recently studied exposed fossilized coral reefs from Panama's Bocas del Toro Province and the Dominican Republic, comparing them with nearby modern reefs. These exceptionally well-preserved reefs date back 7,000 ...
