Accounting for cell components in saliva increases the reliability of biochemical tests for experience-driven epigenetic changes.
Researchers from the University of California, Irvine, Georgetown University and the University of Rochester have found that specific small molecules in blood plasma may be useful in determining whether someone has sustained a mild traumatic brain injury (mTBI), commonly known as a concussion.
Genetic recombination is vital to natural selection, yet some species display far more crossover than others. Scientists in Rochester have discovered a gene in fruit flies that is responsible for the evolution of these recombination rates.
There's increasing physiological evidence connecting breathing patterns with the brain regions that control mood and emotion. Now researchers have added neurons associated with the olfactory system to the connection between behavior and breathing. Connecting patterns in these interactions may help explain why practices such as meditation and yoga that rely on rhythmic breathing can help people overcome anxiety-based illnesses.
In a large population-based study of randomly selected participants in Germany, researchers found that participants aged 65-74 years with olfactory dysfunction showed impaired cognitive performance. Interestingly, this strong association was not present in younger (55-64 years) or older (75-86 years) participants. Additionally, the effect was more present in women than men.
New research suggests that rather than dampen immunity, endurance sports, like this weekend's London Marathon, can actually boost the body's ability to fight off illness.
In a student-led study, one hour of mindfulness meditation shown to reduce anxiety and some cardiovascular risk markers.
By analyzing genes of two distinct groups of the KhoeSan, investigators were able to find a level of diversity and divergence in immune cell repertoires much higher than identified in any other population. The findings are described in an article published this month in The Journal of Immunology.
Astronomers developed a 'guide star' adaptive optics technique to obtain the most crystal-clear and precise telescopic images of distant galaxies, stars and planets. Now a team of scientists are borrowing the very same trick. They've combined it with lattice light-sheet to create a new microscope to capture unprecedented images of biology. The work -- a collaboration between researchers at Howard Hughes Medical Institute, Boston Children's Hospital and Harvard Medical School -- is detailed in a new paper in Science.
Researchers from LSTM, with partners from a number of international institutions, have shown the rapid selection of a novel P450 enzyme leading to insecticide resistance in a major malaria vector.
