Mars' largest moon, Phobos, has captured public imagination and been shrouded in mystery for decades. But numerical simulations recently conducted at Lawrence Livermore National Laboratory (LLNL) have shed some light on the enigmatic satellite.

A team of physicians and laboratory scientists has taken a key step toward a cure for sickle cell disease, using CRISPR-Cas9 gene editing to fix the mutated gene responsible for the disease in stem cells from the blood of affected patients. For the first time, they have corrected the mutation in a proportion of stem cells that is high enough to produce a substantial benefit in sickle cell patients.

The nearby star Proxima Centauri hosts an Earth-sized planet (called Proxima b) in its habitable zone but the star seems nothing like our sun. It's a small, cool, red dwarf star only one-tenth as massive and one-thousandth as luminous as the sun. However, new research shows that it is sunlike in one surprising way: it has a regular cycle of starspots.

The US has one of the highest rates of obesity in the world, with soda consumption identified as one of the factors. On average, Americans consumed 46 gallons of soda in 2009, giving the US one of the highest rates of per capita soda consumption of any country. A recent report estimated that soda consumption caused one-fifth of weight gain in the US between 1977 and 2007.

Although individuals often consume natural products because of their potential health benefits, a new review indicates that it is not clear whether the benefits of plant-derived compounds that mimic estrogen outweigh the possible health risks.
Phytoestrogens are compounds from plants that are similar in structure to estrogen and are found in a variety of foods, especially soy. Some women may consume phytoestrogens promoted as natural alternatives to hormone replacement therapy to help ease menopausal symptoms such as hot flushes or to protect against bone loss.

Ever since the 1973 oil embargo, U.S. energy policy has sought to replace petroleum-based transportation fuels with alternatives. One prominent option is using biofuels, such as ethanol in place of gasoline and biodiesel instead of ordinary diesel.
Transportation generates one-fourth of U.S. greenhouse gas emissions, so addressing this sector’s impact is crucial for climate protection.

The human genome is far more complex than thought, with genes functioning in an unexpected fashion that scientists have wrongly assumed must indicate cancer, according to a new paper on what is called chimeric RNA – genetic material that results when genes on two different chromosomes produce "fusion" RNA in a way scientists say shouldn’t happen. Researchers have traditionally assumed these chimeric RNA are signs of cancer, of something gone wrong in the genetic transcription process.

A paper by researchers at LSU Health New Orleans in a little known journal called Translational Cancer Research suggests that age is an important factor in the association between cancer and sugar-sweetened beverages and recommends that intervention programs to reduce consumption of added sugar be focused on lower socio-economic status, young males, as well as cervical cancer survivors.
