Beyond changing DNA itself, mutagens also cause errors in gene transcription
Exposure to mutagens, or mutation-causing agents, can not only bring about changes in DNA but also appear to induce errors when genes are transcribed to make proteins, which may be an important factor in age-related diseases......»»
Polar bears are sustaining ice-related paw injuries in a warming Arctic
Polar bears in some parts of the high Arctic are developing ice buildup and related injuries to their feet, apparently due to changing sea ice conditions in a warming Arctic. While surveying the health of two polar bear populations, researchers found.....»»
A blueprint for mapping melting ice sheets: Open-source tool can help make radar systems at a fraction of the cost
Researchers in the Stanford Radio Glaciology lab use radio waves to understand rapidly changing ice sheets and their contributions to global sea-level rise. This technique has revealed groundwater beneath Greenland, the long-term impacts of extreme m.....»»
New ice core data provide insight into climate "tipping points" during the last Ice Age
A changing climate triggers a sudden shift in ocean circulation, creating weather havoc and plunging Earth into an abrupt new Ice Age......»»
Scientists uncover how transcription drives motion within the genome
A team of scientists has discovered surprising connections among gene activity, genome packing, and genome-wide motions, revealing aspects of the genome's organization that directly affect gene regulation and expression......»»
Modeling experiments show weather-changing El Niño oscillation is at least 250 million years old
The El Niño event, a huge blob of warm ocean water in the tropical Pacific Ocean that can change rainfall patterns around the globe, isn't just a modern phenomenon......»»

Forest fires are shifting north and intensifying—here"s what that means for the planet
Fires have long been a natural part of forest ecosystems, but something is changing. Our new study shows that forest fires have become more widespread and severe amid global heating, particularly in the high northern latitudes such as Canada and Sibe.....»»
Single-molecule imaging reveals aberrant DNA-binding dynamics of cancer-linked chromatin remodelers
Biophysical chemists from the National University of Singapore (NUS) have uncovered a previously hidden landscape that governs the intracellular organization and dynamics of SWI/SNF chromatin remodelers, an important class of protein complexes that c.....»»
Resolving biology"s dark matter: DNA barcoding reveals hidden insect diversity
There are millions of species on Earth that we still know nothing about. Researchers call these species "biological dark matter," but new methods can provide us with a better overview more quickly......»»
DNA-binding C2H2 zinc finger proteins also regulate RNA processing, researchers discover
Researchers at the University of Toronto have shown that an important class of DNA-binding factors can also bind to RNA, regulating gene expression through various mechanisms. The study significantly expands our understanding of these proteins' funct.....»»
Environmental DNA and epidemics in wood frogs: Collaboration examines eDNA"s precision in population size estimation
Tracy Rittenhouse, associate professor of natural resources and the environment in UConn's College of Agriculture, Health and Natural Resources (CAHNR), was doing an experiment to study ranavirus epidemics in wood frogs. When Meghan Parsley, then a P.....»»
Pathogenic system found on Providencia rustigianii has virulence gene akin to Salmonella"s
Salmonella and E. coli are well-known bacteria that cause food poisoning, but less understood are species of Providencia, another causative agent of serious symptoms......»»
Donald Trump Wants to Make Eugenics Great Again. Let’s Not

DNA confirms these 19th-century lions ate humans
“Tsavo Man-Eaters” killed dozens of people in late 1890s, including Kenya-Uganda Railway workers. For several months in 1898, a pair of male lions turned the Tsavo region of K.....»»
Hybrid quantum error correction technique integrates continuous and discrete variables
A major challenge in realizing quantum computers is the development of quantum error correction technology. This technology offers a solution for addressing errors that occur in the qubit, the basic unit of quantum computation, and prevents them from.....»»
