Activating an executioner sounds like an unwise proposition, but the idea has produced a potent new small molecule for killing cancer cells, according to work presented at the ACS national meeting in San Francisco.
The science of paleontology has a long way to go. Maybe the intellegent design camp should wait to pass judgement on evolutionists until then.
Some call is streamlining. Others call it cutting corners. A judge has ruled on the EPA approval method of pesticides and said that the EPA is cutting corners, which results in rules that are "less protective" of endangered species.
The structure of an enzyme in avian influenza may give clues on how we can develop drugs to combat this disease. A classic example of structure-based drug design in progress.
The force of collions between two galaxy clusters has had the strange effect of separating dark matter and ordinary matter.
Having shown in recent years that three of the five basic taste modalities−bitter, sweet, and the savory taste of monosodium glutamate known as umami−work via dedicated subpopulations of taste cells and receptors, Charles S.
University of Arkansas scientists have published a journal article (Journal of Physical Chemistry B) about creating "paper" from nanowire material that you can fold, bend, cut, heat (up to 700 C with no effect), or use as a filter and is chemically inert.
Researchers report progress toward development of a drug to treat measles, which remains one of the world's most devastating infectious diseases despite availability of a vaccine to prevent it.
Instead of black holes, new evidence suggests that these phenomena are actually a body of definate size and gradually crams itself into a smaller object forever, but never achieves a black hole infinitely small.
A primate protein, called retrocyclin, was found to be highly effective in treating HIV infections. Humans have the genes to synthesize retrocyclin, but a stop codon prevents the natural production of this peptide.
This could be the breakthrough that really allows peptide therapeutics to thrive by increasing their effectiveness, their robustness, and expanding their possible functions.
Interesting list of need-to-know science facts. I do think that if you know them, you can probably convince most people that you're either a scientist or at least dabble in science as a hobby.
Is Pluto not a planet? Or are as many as 14 other objects planets? The International Astronomers Union may be forced to downgrade Pluto or they face the prospect of adding as many as 14 other objects.
An exciting discovery about the nature of Alzheimer's disease breathes new life into completely different type of treatment. Scientists have determined that the body employs molecular "janitors" that clear away the sticky plaque blamed for Alzheimer's.
Good news for those who like aligote more then pinot noir.
Chemists weigh in on how conceivable for liquid explosives to be made and to bring down a plane.
A new report in Nature [1] describes the nature of one protein that counters the conventional view on how proteins fold.

Scientists at Los Alamos National Laboratory have come up with a new primary explosive for ammunition that is more environmentally friendly and safer to produce and use.
What would you expect if you take tightly coiled shoelaces and pull the ends. Well, one would see that the coils would be stressed and would try to unwind. DNA, a double helix molecule, would be expected to do the same, but Prof. Bustamante has proof that it's not that simple.
By combining an engineered protein derived from jellyfish that fluoresces within heart cells with the activation of protein kinase A (PKA), scientists have been able to elucidate the interacting biochemical pathways in heart cells that involve PKA.
A tiny star with a giant planet is further muddling astronomers' notion of what a planet is. The planet is one of perhaps only two or three around other stars to be photographed directly, but it may be more like a star than a planet.
We're trying to say one step ahead of the ever-changing, evolving HIV virus.
Environment Canada (EC) and Health Canada have proposed to control, limit, or ban widely used stain repellents that keep fast-food grease off clothes and nasty stains off carpets.
Researchers have reported making progress in developing a vaccine that would induce the body to attack the hormone ghrelin, which was recently discovered to decrease energy expenditure and fat breakdown.
According to the Commission for Environmental Cooperation, the amount of industrial chemical releases in North America fell by 20%.
