We summarize the week's scientific breakthroughs every Thursday.
- Plants
Fifty years ago, ethylene research ripened
In 1965, scientists realized ethylene was the molecule that ripens fruit.
- Animals
Wild dogs cause problems for people in Nepal
The endangered dhole has a reputation for killing livestock, but its taste for blue sheep could also be an issue, a new study finds.
- Genetics
White House hits pause on editing human germline cells
The White House has hit pause, for now, on clinical experiments that could alter the human germ line.
- Neuroscience
Diet and nutrition is more complex than a simple sugar
A new study shows that fructose may leave you wanting more when compared to the same dose of glucose. But in studies of single nutrients, it’s important to be cautious.
- Genetics
Genes and environment balance each other
Genes and environment have equal influence on human traits.
- Neuroscience
No-pain gene discovered
Scientists have identified a new genetic culprit for the inability to perceive pain.
- Genetics
A billion years of evolution doesn’t change some genes
Human genes can substitute for 47 percent of essential genes in baker’s yeast, new research shows.
- Animals
These birds provide their own drum beat
Male Java sparrows use bill clicks in their songs, which they learn from their dads.
- Climate
Tranquil ecosystems may explain wild swings in carbon dioxide stashing
Semiarid ecosystems, such as grasslands and shrublands, are behind the large variation in the amount of atmospheric carbon dioxide sucked in by land each year.
- Genetics
Mutations that drive cancer lurk in healthy skin
Healthy tissue carries mutations that drive cancer, samples of normal skin cells show.
- Neuroscience
Brain implants let paralyzed man move robotic arm
Implanting tiny silicon chips in the action-planning part of a paralyzed man’s brain let him smoothly control a robotic limb with his thoughts.
- Genetics
Ancient DNA pushes back timing of the origin of dogs
DNA extracted from the fossil of an ancient wolf indicates dogs and wolves diverged longer ago than previously thought.
