A small protein called ubiquitin marks abnormal sperm cells, including cells that have two heads, two tails or are otherwise misshaped. This “recycling tag” on…
These findings by Julie Kerns, Ph.D., a postdoctoral researcher in the Hutchinson Center’s Basic Sciences Division, published Jan. 25 in the open-access…
“The majority of DNA in our bodies is packaged, or tightly structured,” said Gregory Crawford, Ph.D., a researcher in the IGSP and one of the senior…
Like fine china and crystal, which tend to be used sparingly, stem cells divide infrequently. It was thought they did so to protect themselves from unnecessary…
This new study shows that genes – which are parts of double-stranded DNA with a double-helix structure containing a pattern of chemical bases – can recognise…
The team, in collaboration with Charles University, Prague, found that field mice sacrifice some of their immunity protection in favour of a more rapid…
The shells of diatoms are so heavy that when they die in the oceans they typically sink to watery graves on the seafloor, taking carbon out of the surface…
As a synthetic chemist fascinated by natural products and their potential in medicine, Scheidt knew what he had to do: Make that molecule. After six months of intense effort, Scheidt, graduate student Daniel Custar and postdoctoral fellow Thomas Zabawa successfully built the molecular structure reported in the paper. That’s when they discovered something strange and unexpected when they compared the spectra, or unique molecular fingerprints, of their structure and that of the natural compound: The spectra did not match, which…
