Using a mobile MRI scanner to image the brains of prison inmates, researchers have found that the brains of people who show signs of psychopathy are wired in a way that leads them to over-value immediate rewards and neglect the future consequences of potentially dangerous or immoral actions.
Researchers developed ways to temporarily eliminate the sense of smell in adult mice, and discovered that those mice that lost smell could eat a high-fat diet and stay a normal weight, while littermates that retained the sense of smell ballooned to twice normal weight. Supersmellers gained more weight than did normal mice on the same high-fat diet. Smell-deficient mice burned excess fat instead of storing it, suggesting a link between smell and metabolism.
A new method has been developed to image cancer at the single-cell level by using chemical techniques to make whole mouse bodies and organs highly transparent. Combining their preparation with existing imaging technology, they were able view cancer cells multiplying within organs, including the lungs, intestines, and liver, and traveling through the body to and from new tumors in distant locales.
Trihydrogen, or H3+, has been called the molecule that made the universe, where it plays a greater role in astrochemistry than any other molecule. While H3+ is astronomically abundant, no scientist understood the mechanisms that form it from organic molecules.
To help stem the tide of rhino poaching, some biotech companies are seeking to develop and manufacture synthetic horns that are identical to the real thing. New research shows that, for conservation purposes, it may be beneficial to produce synthetic horns that are engineered to be undesirable but difficult for buyers to distinguish from wild horns to create uncertainty in the market and drive out wild horn suppliers through adverse selection.
A new study has succeeded in observing the fertilization capacity of the sperm cell before its insemination in the oocyte. Researchers put male gametes in contact with the cytoplasm of female animal gametes to see if they perform their functions properly. The technology studies the incidence of sperm morphology, concentration, and motility in the embryo formation process.
A woman who ate her placenta after giving birth wound up spreading a potentially deadly infection to her baby, according to a new report of the case.
Summers around the world are already warmer than they used to be, and they’re going to get dramatically hotter by century’s end if carbon pollution continues to rise.
Just like humans, many fish like to surround themselves with active companions -- but frisky friends also make for fierce competition. New research reveals that minnows would rather swim with their most active friends, even if they pose more of a threat.
