Reaction to coffee in your genes
Caffeine affects different people in different ways—and genetics could be the reason. Scientists have previously believed there is a genetic connection between individual responses to caffeine, but singling out the specific genetic variants has been a challenge. A recent study published in Molecular Psychiatry, however, provides new insight.
Researchers from the Harvard School of Public Health and Brigham and Women’s Hospital in Boston performed a meta-analysis on 120,000 regular coffee drinkers. Participants came from different ancestries–American, European and African ancestry.
Two gene variants were identified in connection to caffeine metabolism: POR and ABCG2. Two other gene variants near genes BDNF and SLC6A4 were associated with the “reward” effect of caffeine Also, the genesGCKR and MLXIPL, which play a role in glucose and lipid metabolism, were connected to the metabolic and neurological effects of caffeine for the first time.
The study is believed to be a major step forward in the research of coffee effects. It could help scientists identify subgroups of people most likely to benefit from increasing their coffee intake and those who would be better off if they cut back.

More Ebola screenings for travelers
More stringent screenings for the Ebola virus will be imposed on people traveling to the U.S. from West Africa, President Barack Obama announced yesterday, although he noted that the government will not ban people from traveling to the U.S. from that region.
A White House spokesman said airline travel to and from West Africa would not be stopped because officials did not want to negatively affect systems that are being used to send supplies and personnel to the hardest-hit countries in Africa.
People leaving Ebola-affected countries now are asked to fill out a questionnaire on whether they have symptoms such as a high fever and whether or not they have had any contact with someone who was diagnosed with Ebola. In Liberia, they also are scanned for fever.
Ebola is a deadly virus but one that is spread through bodily fluids, such as blood and saliva, and not through the air. So far, of the 10 people exposed to the virus through Thomas Eric Duncan, the Ebola patient is a Dallas hospital, none are currently showing Ebola symptoms. Duncan remains in critical condition and is said to be “fighting for his life.”
Concern about the virus is also high in Europe, where the first case of Ebola being contracted outside of West Africa was reported on Monday. Spanish health officials said a nurse who treated a priest brought to Madrid with Ebola last month, and who died of the disease, had also been infected.
