Don't judge a substance by its smell: hydrogen sulfide, a gas more associated with flatulence than healthcare, is the key ingredient of a new compound designed to treat issues relating to heart attack, stroke, and dementia.
Researchers believe women who have their last child after 33 are more likely to live into their late nineties. The findings are a matter of genes, meaning the relationship between late motherhood and long life is correlative, not causative.
PETA ruffled feathers last month with a misleading ad campaign that suggested consumption of dairy products led to autism. The organization, already widely derided for its sensationalism, has an uphill road to climb if it ever wants to be taken seriously again.
Despite the ivory trade having been prohibited for 25 years, tens-of-thousands of elephants are illegally killed in Africa every year. The West African nation of Togo has turned to technology to help it combat ivory smuggling.
Some scientists believe that humanity's best shot at colonizing other planets lies in working within existing physics using organisms -- in this case, bacteria encoded with human DNA -- that can survive the trip.
To all the external things that bring people together, add genetics: A new study discovered that husbands and wives were more genetically similar to each other than they were to other randomly selected individuals.
Using data from one of the world's oldest continuing studies of aging men, researchers have discovered a possible connection -- in the form of a certain type of gene -- between body height and lifespan.
Until now, it was hard for geneticists to tell which parent or family line was the source of a particular genetic variant. The technique will enable improved risk assessment for diseases and refine organ matches for donors and recipients.
Junk DNA -- so called because it was thought to have no biological function -- may actually play a role in determining facial shape, say scientists.
A new study is only the latest to link higher-than-average facial width to certain unsavory behaviors, including -- in this case -- the propensity to cheat. However, the researchers warn not to judge a book by its cover.
New research suggests that people are largely biologically programmed to wake up and fall asleep at certain times. Those with "late" programming tend to struggle more with traditional work schedules, and can experience health problems as well.
More than 60 years after her death, Lacks' genetic material can no longer be used by researchers without family consent. Is the same true for the rest of us? Not exactly.
Despite data indicating that rhesus macaques exhibit many of the same traits that caused the recent reconsideration of chimpanzee use in research, it's unlikely that another scaling-back will take place any time soon.
Because it's not all our fault: Almost a quarter of US methane emissions come from livestock in the form of burps and farts. Now, a study is looking into ways to reduce that output via selective breeding.
By altering genes that influence mosquitoes' response to odors, researchers at the Howard Hughes Medical Institute have created an insect that won't necessarily choose a human to sting first.
