...sue of the journal, Science. "The Y chromosome is nice because it does not recombine," says Shriver. "A lot more evolutionary information is available than is found in mitochondrial DNA." Mitochondrial DNA is non-nuclear genetic material passed from mothers to their children and has been used for some ...Smart polymers provide size-selective switches to turn proteins on, off
...s now, Stayton said. This indicates another, very nice way to do it. The diminutive size of the proteins and molecules involved could open avenues into advanced concepts like lab on a chip the ability to fit a full range of laboratory functions on a single computer chip.

"The nice thing about most biological therapies, including this adenovirus, in combination with standard therapy is they don't increase toxicity to the patient. Research also suggests that adenovirus and chemotherapy may have synergistic anti-tumor activity," ...Study of poisonous snakes boosts old Batesian principle of mimicry
...f it's really mimicry? he said. "Lots of other nice studies of mimicry have been done, but we believe ours is the first to really test this critical prediction, which is that where there's no dangerous model present, then the protection from mimicry should break down," Pfennig said. "If the model that...Gene-trapping method powers discovery of new brain-wiring signals

...e proteins they produce, and the zebrafish makes a nice model for that." Scientists study proteins and gene function by disabling a single gene, and then raising clones of that test subject to see how they develop without the missing gene. Such experiments are called knockout experiments, because the gene...Card tricks and mathematics: Applying the magician's trade to numerical dilemmas

Research suggests that many of these women also have a type of insulin resistance similar to that seen in type 2 diabetes. The body produces excess insulin to ensure that all c...Legumes found to contain starch carrying a fiber-like punch

You always think of legumes for their protein, as you should. With their protein, fiber and resistant starch...Oncogene spawns further mutation in breast cancer study

According to Chodosh, cancer is basically the progress of uncontrolled cell reproduction. The mechanisms that cells use to divide go o...DNA deletion offers new evidence of mammals' origins

One nice thing about naltrexone, even now, is that it needs to be taken only once a day, which is very important for medication compliance, especially in an alcoholic population who may be ambivalent about taking medications to begin with.
