Virtually all cases of cervical cancer are caused by persistent infections from several of the human papillomaviruses (HPV) — a family of viruses that also…
By silencing the gene, caspar, the researchers were able to block the development of the malaria-causing parasite in Anopheles gambiae, A. stephensi and A….
The tool is also commonly used for “stand-off” detection in such harsh or potentially dangerous environments as blast furnaces, nuclear reactors and biohazard…
Although scientists have known for more than a century that small populations of closely related plants or animals are likely to suffer from low reproductive…
Many bacteria are able to “swim” through liquids by means of a flagellum. When doing this, some bacteria follow attractants, some flee from harmful substances,…
The research is available online and featured on cover of the March issue of Molecular Ecology.Some large organisms like aspen trees and sea anemones are…
Their discovery, detailed in the March 13 issue of Science, solves a longstanding puzzle about the underlying biochemical mechanisms that control plant clocks…
Researchers at the University of Illinois have identified a novel pathway that controls the activity of a key protein involved in inflammation. Their findings…
The trick becomes how to deliver cancer-fighting drugs directly to the tumor cells. Brown University chemists think they have an answer: They have created a…
A family of genes known as the “FET” genes has been investigated in the work presented in the thesis. This family contains three genes that are found in…
Gray or white hair develops with advancing age in an entirely natural aging process which results in the generation of less and less color pigments. Researchers of the Johannes Gutenberg University Mainz in Germany und the University of Bradford in Great Britain have now unlocked the secret of hair turning white or gray in old age. According to them, free oxygen radicals are significantly involved in the loss of hair color. “The originator of the entire process is hydrogen peroxide, which we also know as a bleaching agent,” explains Professor Heinz Decker of the Institute of Biophysics at Mainz University….
The study, in the journal Structure, reveals that after eons of gradual evolution, proteins suddenly experienced a “big bang” of innovation. The active regions…
The alga — a simple one-celled algae called Cyanidioschyzon — thrives in extremely toxic conditions and chemically modifies arsenic that occurs naturally…
More than 150 years after a small Eurasian tree named tamarisk or saltcedar started taking over river banks throughout the U.S. Southwest, saltcedar leaf…
