Once-endangered Kirtland’s warblers show extensive signs of inbreeding in genome

The genome of a once-endangered songbird shows extensive signs of inbreeding, according to a new study by Penn State researchers. Because inbreeding can negatively impact survival and reproduction, the results could guide continuing conservation efforts for Kirtland’s warblers, whose populations still rely on extensive management. The new study, published Dec. 9 in the journalEvolutionary Applications, […]

Insect genome offers insights into rare biological conditions, agricultural biosecurity

Lice live their entire lives with a set of genes that in humans would indicate a late-stage degenerative disorder such as Parkinson’s or Alzheimer’s disease. How do lice tolerate this genome structure that in humans and many other animals would result in major neurodegenerative problems? “We’re a long way from connecting those dots,” said Stephen […]

Close encounters between distant DNA regions cause bursts of gene activity

Researchers at Kyushu University have revealed how spatial distance between specific regions of DNA is linked to bursts of gene activity. Using advanced cell imaging techniques and computer modeling, the researchers showed that the folding and movement of DNA, as well as the accumulation of certain proteins, changes depending on whether a gene is active […]

Single mutation in H5N1 influenza surface protein could enable easier human infection

A single modification in the protein found on the surface of the highly pathogenic avian influenza (HPAI) H5N1 influenza virus currently circulating in U.S. dairy cows could allow for easier transmission among humans, according to new research funded by the National Institutes of Health (NIH) and published today in the journal Science. The study results […]

Conservation paradox: Invasive species are often threatened in their native range

Non-native species introduced by humans are among the main causes of global species decline – they were partly responsible for 60 percent of the species that have become extinct worldwide in recent decades. In Central Europe, non-native mammals include species such as the Norway rat, the mouflon and the mink. Now a study led by […]

From one gene switch, many possible outcomes

The University of Pennsylvania’s Aman Husbands, of the School of Arts & Sciences, uncovered surprising ways transcription factors, the genetic switches for genes, regulate plant development. Their findings reveal how subtle changes in a lipid-binding region called the START domain can dramatically alter gene regulation, paving the way for advancements in crop engineering, synthetic biology, […]

Feeding grazing cattle seaweed cuts methane emissions by almost 40%

Seaweed is once again showing promise for making cattle farming more sustainable. A new study by researchers at the University of California, Davis, found that feeding grazing beef cattle a seaweed supplement in pellet form reduced their methane emissions by almost 40% without affecting their health or weight. The study was published today (Dec. 2) […]

A proteome-wide yeast degron collection for the dynamic study of protein function

Genome-wide collections of yeast strains, known as libraries, revolutionized the way systematic studies are carried out. Specifically, libraries that involve a cellular perturbation, such as the deletion collection, have facilitated key biological discoveries. However, short-term rewiring and long-term accumulation of suppressor mutations often obscure the functional consequences of such perturbations. We present the AID library […]

Conserving high-elevation grasslands in Peru is key to protect Andean bears

Andean bears carefully select the best foraging locations and plants to maximize nutrition and avoid livestock, according to a study publishing December 18, 2024, in the open-access journal PLOS ONE by Nicholas Pilfold at the San Diego Zoo Wildlife Alliance in California, U.S., and colleagues. Andean bears, also known as ‘spectacled bears’ because of the […]
