A hybrid rice plant has been engineered to clone its own seeds, raising hopes of producing a higher volume of plants more economically, according to findings published online in Nature. Researchers got the plants to clone their seeds by turning off a trio of genes and subsequently using CRISPR-Cas9, enabling asexual reproduction.
The risk of stroke among black women in their late 60s and early 70s equals that of black men the same age, while white women have a lower risk of ischemic stroke than white men from ages 45 to 74, researchers reported in JAMA Neurology. They found that the lower risk of stroke among black women, compared with black men, only lasts until age 64.
The Detroit-based Gilbert Family Foundation will distribute $12 million in grants over the next three years to gene therapy research projects focusing on the genetic disorder neurofibromatosis type 1.

Anxious macaques become calmer when they observe other macaques grooming each other, according to findings published in Proceedings of the Royal Society B. Researchers say the effect resembles emotional contagion in humans, who tend to become more cheerful when in the company of cheerful people.
Infants who had initial cold symptoms lasting at least three weeks had less varied nasal microbiota that were more likely to be dominated by the Streptococcaceae or Moraxellaceae families, compared with those with a faster initial cold recovery, according to a Swiss study in the journal ERJ Open Research. Researchers said the findings may prompt better understanding of how respiratory tract bacteria function in infections and in asthma and other chronic conditions.
An Oregon school district is in its third year of a career and technical education program in which students are learning skills such as building fences, construction and gardening. Neely Kirwan, the district's curriculum director, says the program helps to expand students' horizons.
Students at a middle and high school in New Hampshire are learning from a new farming machine, FarmBot -- a programmable device that automatically plants and tends to crops. Career and technical education students, including metals and robotics students, built the machine.
The potential for advancement available in the food industry is one of the most exciting parts of the sector, said WFF CEO and President Hattie Hill. In this interview, Hill discusses the history of WFF as well as the evolving mission of the organization.
An approximately 8,000-year-old skull found almost 50 years ago near a burned human bone did not belong to a victim of cannibalism, as previously thought, but instead to a man killed by a blow to the head, according to a new analysis submitted to but not yet published by a peer-reviewed journal. Researchers in Poland took a closer look at the skull with a CT scanner and a scanning electron microscope and found that the wound showed evidence of healing, suggesting the man lived for about a week after he suffered the injury.
