Like a burglar tripping an alarm, infectious threats within the body set off a chain reaction of signaling events that enable the immune system to mount a…
When water freezes or boils, its atomic structure undergoes a phase transition in response to temperature change. Phase transitions are common in nature, and…
Molecular imaging allows molecules in a living organism to be visualized, and provides a means of observing the distribution and behavior of molecules. One of…
Smaller and smarter: this is the aim of research in the quest for ever faster electronic devices smaller in size but capable of performing more complicated…
A team of McGill chemists have discovered that a technique known as photoacoustic infrared spectroscopy could be used to identify the composition of pigments…
The effects of climate change, overfishing, chronic oil pollution and predation by introduced mammals are among the major factors cited repeatedly by penguin…
The research sheds new light on the genetic components of academic performance during middle and high school, and on the interplay of specific genes and…
Walter Trahanovsky, an Iowa State professor of chemistry who likes to write out the chemical structures of compounds when he talks about his science, was…
The finding could have implications for studying X chromosome-linked diseases such as Rett syndrome, caused by mutations in a gene located on the X chromosome.The findings differ from those seen in mouse skin cells that are reprogrammed into iPS cells, in which the inactive X chromosome reactivates, said Kathrin Plath, senior author of the study and a scientist with the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA….
“During chemotherapy or radiation therapy that kills cancer cells by inducing significant DNA damage in their genomes, one of the main side effects for human…
One of the key drivers of human evolution and diversity, accounting for changes that occur between different generations of people, is explained by new…
Plants are good at doing what scientists and engineers have been struggling to do for decades: converting sunlight into stored energy, and doing so reliably…
“Bee numbers may have declined at our research site, but we suspect that a climate-driven mismatch between the times when flowers open and when bees emerge…
Professor Colin Hill who is presenting his work at the Society for General Microbiology's autumn meeting in Nottingham today describes how bacteria use…
The selfish behaviour of these uncooperative bacteria could be exploited to treat antibiotic-resistant infections, according to research being presented at the…
In a paper appearing in the current issue of The Biological Bulletin, scientists propose that a third type of catalyst could have jumpstarted metabolism and…
