First exoplanet confirmed to be tidally locked to its star.

LHS3844b is a large rocky planet revolving around a star located about 48.5 light years from Earth. It has been confirmed in recent study that it is tidally locked with its star.  The observations of intensities light reflected from it throughout it's transit around it's star could be used to estimate it's days-side surface temperature. It's surface temperature is estimated to be about 1300 degree Celsius. 

Making long, thin rice grains.

Long, shiny rice grains are considered to be a measure of rice quality in many parts of the world. Like most qualities of any living being, the length of the rice grain also is encoded by genes. Research group in China have narrowed down to a single gene responsible for the grain length (Wang et al., 2015). The gene, Os07g0603300, is present on Chromosome 7 of rice (Oriza sativa L.) genome. When the gene was duplicated in tandem i.e if two copies of the genes were present back to back, the length of the grains increased. Best part of the exercise was that there was no decrease in the yield of this rice plant. After breeding this rice line with other varieties of rice can further increase the grain quality.
Problem remains however of the acceptance of this GM variety. Humans have been changing the genetic compositions of plants/animals since we started domestication them by breeding them. Genetic engineering is just a targeted breeding. Hope someday people would understand.
