When normal and gene-altered mice ate the high-fat diet -- along with varying levels of doxycycline to induce GLP1 release -- mice expressing GLP1 (left) gained less weight gain while normal mice (right) grew fat. Credit: Wu Laboratory, the University...
Imagine a future where a guided biomachine put into your body seeks out defective gene sequences in each cell and edits in the correct information with precision accuracy. It's called gene editing, and University of Alberta researchers have just published...
An international team of scientists have identified candidate resistance genes that could protect ash trees from the Emerald Ash Borer (EAB), a deadly pest that is expected to kill billions of trees worldwide. In the new study, published today in Nature...
The earliest multicellular organisms may have lacked heads, legs, or arms, but pieces of them remain inside of us today, new research shows. According to a UC Riverside study, 555-million-year-old oceanic creatures from the Ediacaran period share genes with today's...
Chimps working on the number sequencing task. Credit: Christopher F Martin A new study from Kyoto and Oxford universities and Indianapolis Zoo has shown chimpanzees spontaneously taking turns to complete a number sequencing task. Previous studies have shown chimps...
A team that includes the scientist who first harnessed the revolutionary CRISPR-Cas9 and other systems for genome editing of eukaryotic organisms, including animals and plants, has engineered another CRISPR system, called Cas12b. The new system offers improved capabilities and...
A team of researchers from several institutions in the U.K. has found evidence that suggests some seabirds may benefit from the existence of human-built offshore structures. In their paper published in the journal Communications Biology, the group describes their study...
Researchers have made a major breakthrough in developing gene-editing tools to improve our understanding of one of the most important ocean microbes on the planet. The international project, co-led by scientists at the University of East Anglia (UEA) in the...
These are water droplets on a lotus leaf. Credit: C. Falcón Garcia / Technical University of Munich Dental plaque and the viscous brown slime in drainpipes are two familiar examples of bacterial biofilms. Removing such bacterial depositions from surfaces is often...
Human chromosomes are stained blue (DAPI) with ribosomal DNA in green (FISH probe). Credit: Image courtesy of Tamara Potapova, Ph.D. Research from the Stowers Institute provides evidence suggesting that cancer cells might streamline their genomes in order to proliferate more easily....
Telomerase, an enzyme naturally found in the human organism, is the closest of all known substances to a "cellular elixir of youth." In a recent study, Brazilian and US researchers show that sex hormones can stimulate production of this...
