In Norway, Climate Goals Clash With Indigenous Herders’ Rights – State of the Planet

A recent climate initiative by the Norwegian government is facing opposition from the Saami Indigenous people, whose territories are directly affected. The proposed 54-kilometer power line would be built by the state-owned energy company Equinor in the northernmost portion of the country, well above the Arctic Circle. The Saami believe their rights to cultural preservation […]

From cursed tomb fungus to cancer cure: Aspergillus flavus yields potent new drug

Penn-led researchers have turned a deadly fungus into a potent cancer-fighting compound. After isolating a new class of molecules from Aspergillus flavus, a toxic crop fungus linked to deaths in the excavations of ancient tombs, the researchers modified the chemicals and tested them against leukemia cells. The result? A promising cancer-killing compound that rivals FDA-approved […]

UK antibiotic subscription model key to supporting antibiotic investment

For the world to meet the health challenge posed by increasing antimicrobial resistance (AMR), new ways must be found to overcome the market failure that holds back the development of new antibiotics.  Critical to this is greater understanding of the factors needed to persuade investors to support research and development (R&D) efforts. The latest report […]

Frozen in time: Transparent worms keep genes in sync for 20 million years

Two species of worms have retained remarkably similar patterns in the way they switch their genes on and off despite having split from a common ancestor 20 million years ago, a new study finds. The findings appear in the June 19 issue of the journal Science. “It was just remarkable, with this evolutionary distance, that […]

ALDH9A1 deficiency as a source of endogenous DNA damage that requires repair by the Fanconi anemia pathway

The Fanconi anemia (FA) DNA repair pathway is required for the repair of DNA interstrand cross-links (ICLs). ICLs are caused by genotoxins, such as chemotherapeutic agents or reactive aldehydes. Inappropriately repaired ICLs contribute to hematopoietic stem cell (HSC) failure and tumorigenesis. While endogenous acetaldehyde and formaldehyde are known to induce HSC failure and leukemia in […]

After the ‘Last Generation’

Soul-searching Second, the idea that repression of the movement would act as a ‘backfiring tool’, stirring public sympathy proved overly optimistic. “If they lock us up, there will be an outcry,” some activists claimed. Repression and court cases did not trigger mass support. Instead, the crackdowns dampened the movement’s momentum. Third, the rise of the […]

Monster salamander with powerful jaws unearthed in Tennessee fossil find

A giant, strong-jawed salamander once tunneled through ancient Tennessee soil. And thanks to a fossil unearthed near East Tennessee State University, scientists now better understand how it helped shape Appalachian amphibian diversity. The giant plethodontid salamander now joins the remarkable roster of fossils from the Gray Fossil Site & Museum. The findings appeared in the […]

AI Diagnoses Vocal Cord Paralysis Severity

In a groundbreaking advancement at the crossroads of artificial intelligence and clinical otolaryngology, researchers have unveiled an innovative platform that automatically assesses the severity of unilateral vocal cord paralysis (UVCP) using state-of-the-art deep learning techniques. This pioneering research leverages Mel-spectrograms—a sophisticated audio representation technique—paired with convolutional neural networks (CNN) to dissect subtle vocal characteristics, offering […]

Defying Darwin: Scientists discover worms rewrote their DNA to survive on land

In 1859, Darwin imagined evolution as a slow, gradual progress, with species accumulating small changes over time. But even he was surprised to find the fossil record offered no missing links: the intermediate forms which should have told this story step by step were simply not there. His explanation was as uncomfortable as it was […]
