Borrowing a page from modern manufacturing, scientists from the Florida campus of The Scripps Research Institute have built a microscopic assembly line that…
Revolutions in science come in waves. One of the epoch-making events in modern biology came in 1995 when J. Craig Venter, an American biologist, decoded the…
To find our way, we use maps. Cells use “chemical maps” to find the way: they orient themselves by following concentration gradients of attractants or…
The study, by UBC marine microbiologist Curtis Suttle and PhD student Matthias Fischer, is published online today in Science Express. It describes the marine…
A group of Vienna-based scientists headed by Thomas Marlovits employed recently developed methods of cryo-electron microscopy and have been able to clarify the…
“Leptin resistance is a significant factor, yet the mechanisms that underlie the problem remain unclear,” said Dr. Joel Elmquist, professor of internal…
“We can make cars go,” said Jamie Hestekin, assistant professor and leader of the project. “Our conversion process is efficient and inexpensive. Butanol has…
Craig Wilson, a senior research associate in the Center for Mathematics and Science Education and a long-time butterfly enthusiast, says the numbers of…
Work led by St. Jude Children’s Research Hospital investigators provides fresh insight into mechanisms controlling programmed cell death pathways and offers…
The technique offers a new research tool that can be used to study in detail the mechanism by which viruses attack cells, and might even become the basis for a…
Monitoring the amount of oxygen in living tissues accurately is a valuable tool in biomedical science, because it enables the elucidation of the course of…
Recent molecular phylogenetic analysis has shown that the marine animals known as peanut worms are not a separate phylum, but are definitely part of the family…
Studies of the outermost parts of the cell walls of bacteria yield new information about the chemical composition of structures that are important for the…
The gene for the protein p53 is the most frequently mutated in human cancer. It encodes a tumor suppressor, and traditionally researchers have assumed that it…
Male fruit flies of the Drosophila melanogaster species perform a complex courtship ritual to attract the attention of female flies and make them amenable to…
Physics professors Taekjip Ha and Yann Chemla and combined their expertise in single-molecule biophysics – fluorescence microscopy and optical traps,…
