How New Penguin Species Emerged Across Remote Ocean Islands
Genetic sequencing reveals the first new penguin species in over a century on the Kerguelen Islands, splitting gentoos into four distinct species while parallel breakthroughs uncover cryptic wildcats in South America.
How Cat Scent Recognition Decodes a Hidden Chemical ID
Researchers have identified thirteen branched-chain fatty acids in cat urine that create a durable chemical calling card, solving a long-standing mystery about feline scent recognition and kidney lipid reservoirs.
Malaria Parasite Boosts Transmission Tactics Under Host Stress
When confronted with host stress such as fever, nutrient scarcity, or antimalarial exposure, Plasmodium falciparum activates the AP2-HS regulator and GDV1 loop to accelerate sexual conversion and boost transmission through mosquito vectors.
Smithsonian Links Sally Hemings DNA to Thomas Jefferson
A 15-year Smithsonian genomic investigation led by Richard Kurin connects a historic lock of Thomas Jefferson's hair to Sally Hemings descendants, presenting statistical evidence of paternity while facing academic debate over journal peer review.
Bolivia Yungas Forest Harbors New Cat Species After a Century
Scientists analyzing South American feline genomes have officially described Leopardus tilcayo, a distinct cloud forest tiger cat species native to Bolivia.
Scientists Link Rare Genetic Mutation to Severe Lung Cancer Risk
Scientists have discovered that the rare inherited EGFR T790M mutation elevates lung cancer risk up to 62-fold in nonsmokers, fundamentally altering our understanding of inherited oncological risks.
How Joan Brugge Reshaped Cancer Biology After Family Loss
Following the tragic loss of her sister to a malignant brain tumor in 1970, Joan Brugge turned from mathematics to cellular biology, isolating the SRC protein and pioneering 3D organoids to overcome therapy resistance.
How Daily Step Counts and Cadence Lower Mortality Risk
Researchers from the University of Sydney and Monash University found that mixing stepping intensity with daily step counts significantly reduces mortality risk. The device-based study reveals that brisk cadences compensate for lower overall step totals.
Two Double Helices Reveal How DNA Pairing Can Work
Sheffield and York researchers imaged two DNA double helices aligned side by side. Simulations suggest metal ions support the contact, with cellular relevance still unresolved.
ALS Development Linked to Disruption of Mitochondria-Associated Membranes
Scientists at Nagoya University in Japan have unveiled a connection between the advancement of amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig's disease, and the disturbance observed in mitochondria-associated membranes (MAM). These MAMs serve as the critical junctions where mitochondria and the endoplasmic reticulum (ER) of the cell come into contact.
