Scientists discover gene controlling genetic recombination rates
Genetic recombination is vital to natural selection, yet some species display far more crossover than others. Scientists have discovered a gene in fruit flies that is responsible for the evolution of these recombination rates.

Fat cells seem to remember unhealthy diet
Fat cells can be damaged in a short amount of time when they are exposed to the fatty acid palmitate or the hormone TNF-alpha through a fatty diet, a new study shows. The researchers hope this new knowledge may be used to develop new preventive strategies for diabetes.

Study predicts 2018 flu vaccine will likely have 20 percent efficacy
A new study of 6,610 human flu sequences predicts that this fall's flu vaccine will likely have the same reduced efficacy against the dominant circulating strain of influenza A as the vaccine given in 2016 and 2017 due to viral mutations related to vaccine production in eggs.

Zika presents hot spots in brains of chicken embryos
Zika prefers certain "hot spots" in the brains of chicken embryos, offering insight into how brain development is affected by the virus. If the virus also prefers specific sites in human brains, researchers could look to them for targeted therapies and drug testing.

Unique protein is a vulnerability in the malaria parasite
The malaria parasite is highly dependent on a unique protein for infecting new mosquitoes. This protein could be a target for the development of new drugs.

Active young adults with Type 1 diabetes have muscle complications
A new study has found that poor muscle health may be a complication of Type 1 diabetes, even among active 20-somethings. The researchers found structural and functional changes in the power generation parts of the cell, or mitochondria, of those with diabetes. Not only were the mitochondria less capable of producing energy for the muscle, they were also releasing high amounts of toxic reactive oxygen species, related to cell damage.
