Peering at structures only atoms across, researchers have identified the clockwork that drives a powerful virus nanomotor. Because of the motor’s strength — to scale, twice that of an automobile — the new findings could inspire engineers designing sophisticated nanomachines. In addition, because a number of virus types may possess a similar motor, including the [...]
Long-term gene therapy resulted in improved cardiac function and reversed deterioration of the heart in rats with heart failure, according to a recent study.
The fabled laboratory mouse — from which we have learned so much about how the immune system works — can teach us only so much about how we humans get sick and what to do about it, says a leading researcher.
Researchers have identified a role for the protein IL-21R in a mouse model of atopic dermatitis, a common allergic inflammatory skin disease often known as eczema.
Here’s one more reason to say ’shade grown, please’ when you order your morning cup of coffee. Shade coffee farms, which grow coffee under a canopy of multiple tree species, not only harbor native birds, bats and other beneficial creatures, but also maintain genetic diversity of native tree species and can act as focal points [...]
A predictive link has been established between negative family reactions to their child’s sexual orientation and serious health problems. Negative parental behaviors toward LGB children dramatically compromises their health.
In an important breakthrough in deciphering dolphin language, researchers in Great Britain and the United States have imaged the first high definition imprints that dolphin sounds make in water.
By mixing and matching a contemporary flu virus with the “Spanish flu” — a virus that killed between 20 and 50 million people 90 years ago in history’s most devastating outbreak of infectious disease — researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus.
By leaving the remains of their old exoskeletons, called ‘exuviae’, in and around their colonies, aphids gain some measure of protection from parasites. Parasitoid wasps are likely to attack the empty shells, resulting in a lower attack rate on their previous occupants — much like in the popular ’shell game’ confidence trick.
Scientists have identified a molecular mechanism used by cancer cells to “defend” themselves against chemotherapeutics in an attempt to ensure their own survival. Both the messenger substance nitrogen monoxide (NO) and the protein survivin play a role in this.
