Scientists discover an unexpected food source for tumors

Researchers discovered an antioxidant, glutathione, that cancer cells appear to be “addicted to” as fuel, opening new pathways for investigation and a potential drug that can restrict the way tumors use this nutrient. The top-tier scientific journal Nature is publishing the study online on March 18. Isaac Harris, PhD, and a team from the Wilmot Cancer Institute at the University of Rochester conducted the research. Co-corresponding author and co-first author Fabio Hecht, PhD, and co-first author Marco Zocchi, PhD, led the study in the Harris lab in the Department of Biomedical ...

Cellular stress signal found to drive immune exhaustion and weaken cancer therapy

Cancer-fighting T cells do not simply “run out of energy.” They are molecularly reprogrammed. For years, mitochondrial dysfunction has been recognized as a hallmark of exhausted T cells in tumors. Yet how metabolic stress translates into stable transcriptional reprogramming remained unclear. The new study uncovers a decisive molecular bridge. When mitochondria become depolarized, CD8⁺ T cells increase proteasome activity. This heightened protein degradation selectively dismantles mitochondrial hemoproteins, releasing excess regulatory heme. Rather than remaining a byproduct, heme becomes a signal. It translocates to the nucleus, where it binds and destabilizes the transcription ...

Long dismissed in adult health, the thymus may be critical for longevity and cancer treatment

Two new studies from investigators at Mass General Brigham challenge a decades-old assumption that the thymus, an organ best known for its role in establishing immune function in childhood, becomes irrelevant in adulthood. Using artificial intelligence (AI) to analyze routine CT scans, researchers uncovered that adults with a healthy thymus had increased longevity and reduced risk for cardiovascular disease and cancer. In a separate study of patients with cancer, the researchers found that thymic health may influence response to immunotherapy—a treatment that depends on the strength of a patient’s immune system. These findings, published in two papers in the same ...

Stopping GLP-1 drugs can quickly erase cardiovascular benefits

Following a rapid increase in popularity of GLP-1 drugs for diabetes and weight loss, such as semaglutide and tirzepatide, approximately one in eight U.S. adults now take these medications, which also provide cardiovascular benefits. However, when patients stop taking these drugs, they not only regain weight, but, according to a new study, they also incur increased risk of heart attack, stroke and death compared to staying on the medication. In the study, researchers at Washington University School of Medicine ...

First world map shows impact of the tidal pulse in coastal rivers

Tides not only affect regions along the coast, their periodic fluctuations are carried upstream inland through coastal rivers. River sections particularly affected by these tidal pulses are exposed to an increased risk of flooding. It is therefore important to localize these regions, as well as the extent of the river tide. However, until now, a global and accurate overview has not yet been established. A research team led by TUM has conducted the first global evaluation, based on high-resolution satellite data, and presented it in an interactive map. Over 725 million people worldwide are influenced by river tides The map closes a ...

Study reveals “two-factor authentication” system that controls microRNA destruction

Cells rely on tiny molecules called microRNAs to tune which genes are active and when. Cells must carefully control the lifespan of microRNAs to prevent widespread disruption to gene regulation. A new study led by researchers at Whitehead Institute and Germany’s Max Planck Institute of Biochemistry reveals how cells selectively eliminate certain microRNAs through an unexpectedly intricate molecular recognition system. The work, published on March 18 in Nature, shows that the ...

New ice core studies expand histories of greenhouse gases and ocean temperature to 3 million years

CORVALLIS, Ore. — New analyses of ancient ice from Antarctica and the air contained inside it are extending the history of Earth’s climate records and expanding researchers’ understanding of how the planet has changed over the last 3 million years. The findings, published this week in two papers in the journal Nature, show the long-term cooling of Earth’s climate during this period has been accompanied by only a modest decline in heat-trapping greenhouse gases in the atmosphere. Scientists have known that Earth was much warmer and sea level much higher ...

Psychedelic therapy vs antidepressants for the treatment of depression under equal unblinding conditions

About The Study: In trials of depression, psychedelic-assisted therapy (PAT) was not more effective than open-label traditional antidepressants (TADs). Blinding made a difference for TADs, but not for PAT, confirming that PAT trials are effectively always open label. These results argue against highly optimistic narratives surrounding PAT and highlight the importance of blinding integrity.  Corresponding Author: To contact the corresponding author, Balázs Szigeti, PhD, email balazs.szigeti@ucsf.edu.

Are psychedelics better than antidepressants? New study says no

Psychedelic-assisted therapy may be no more effective than traditional antidepressants when patients know what drugs they are actually taking, according to a first-of-its kind analysis that compared how well each type of drug worked for major depression. Psychedelic-assisted therapy has resisted placebo-controlled testing methods — the gold standard in clinical trial design. Due to their powerful subjective effects, nearly everyone in the trial knows whether they received a psychedelic or the placebo even if they are not told. But in trials of antidepressants, participants may not figure out whether they have received the drug or a placebo, ...

Molecular docking of resveratrol with ovarian cancer-associated proteins and its therapeutic benefits

Ovarian cancer (OC) is a "silent killer" with an annual incidence of 11.2 per 100,000 and mortality of 7.6 per 100,000. Most cases are diagnosed at advanced stages due to the lack of effective screening. Standard treatments—surgery and chemoradiotherapy—are limited by drug resistance, particularly to platinum agents, leading to recurrence and poor prognosis. Natural products like resveratrol (RVT), a polyphenol found in grapes and peanuts, offer potential as safe, multi-targeted adjunctive therapies. This review examines RVT's molecular interactions with OC-related proteins, its therapeutic mechanisms, and novel delivery ...

Female song in Galápagos warblers challenges assumptions about birdsong

For decades, birdsong research focused almost exclusively on males. In many species, however, females also sing. Now a study by researchers from the University of Vienna and Anglia Ruskin University shows that female Galápagos yellow warblers sing frequently, though not for the reasons males do. In experiments simulating territorial intrusions, the researchers found that female song was neither linked to same sex competition nor to signalling aggression in territorial defence. The findings, published in the journal Animal Behaviour, raises new questions ...

Spin separates giant planets from ‘failed stars’

For decades, astronomers have struggled to differentiate giant planets from brown dwarfs, a class of objects more massive than planets but too small to ignite nuclear fusion like true stars.  Through a telescope, these cosmic lookalikes can have the overlapping brightness, temperatures and even atmospheric fingerprints. The striking similarity leaves astronomers unsure if they have observed an oversized planet or an undersized star. Now, a Northwestern University-led team has uncovered a crucial clue that separates the two: how fast they spin. In a new study, astrophysicists found the clearest evidence ...

Target behind cancer drug shown to help fight influenza in mice

A protein already targeted by FDA-approved cancer drugs may also help the body fight influenza, according to new research from The Jackson Laboratory (JAX). Published in Cell Reports, the study found that Programmed Death-Ligand 1 (PD-L1), a protein best known for helping tumors evade immune attack, instead helped immunocompromised mice clear flu-infected lung cells and survive infection. The findings challenge long-standing assumptions about PD-L1’s role in the immune system. While cancer therapies work by blocking PD-L1 to boost immune attack on tumors, the new research suggests that ...
