Citrus is the world’s most economically significant fruit crop, but it faces various environmental adversities that restrict its distribution. Grafting is a crucial factor in enhancing citrus productivity. Current research focuses on selecting genetically uniform rootstocks, such as trifoliate orange for its disease resistance. However, issues such as sensitivity to alkalinity and incompatibility with certain cultivars persist. Addressing these challenges, a study (DOI: 10.48130/frures-0023-0042) published in Fruit Research on 01 February 2024, introduces 'Shuzhen No.1', a novel rootstock ...

People who as teenagers felt pressure to lose weight from family or from the media, females, people who are not heterosexual, and people experiencing socioeconomic disadvantage, are most at risk of ‘internalised’ weight stigma, new research led by the University of Bristol has found. The study is published in The Lancet Regional Health Europe today [15 April]. ‘Internalised’ weight stigma, is when people apply negative obesity-related stereotypes to themselves, such as thinking they are less attractive, less competent, or less valuable as a person because of their weight. This is the first time a study has used a large UK sample to examine who is most at risk. In ...

A new study published in the Strategic Management Journal cautions startups against prioritizing early scaling, as it’s positively associated with a higher rate of firm failure — especially for platform companies. Although managers could see the potential benefits of scaling as a way to prevent competitor imitation, scaling early can also prematurely curtail learning through experimentation and committing to a business idea that lacks product-market fit. Although a few high-growth startups such as Facebook and Uber made their fortunes by scaling early — also known as “blitzscaling” — study authors Saerom (Ronnie) Lee and ...

Scientists have long wondered how the eye’s three cone photoreceptor types work together to allow humans to perceive color. In a new study in the Journal of Neuroscience, researchers at the University of Rochester used adaptive optics to identify rare retinal ganglion cells (RGCs) that could help fill in the gaps in existing theories of color perception. The retina has three types of cones to detect color that are sensitive to either short, medium, or long wavelengths of light. Retinal ganglion cells transmit input from these cones to the central nervous system. In the 1980s, David Williams, the William G. Allyn Professor of Medical Optics, ...
