fingerprint does not contain your genetic code


...THE POWER of genetic information has shaped virtually every aspect of medicine. On one hand, we have learned about diseases and treatments that are now defined by patients’ genomes. Certain genes can predict colorectal cancer with near certainty and, in women, the BRCA mutations, famously discussed by Angelina Jolie, can denote a greater than 80 percent risk of developing breast cancer. We can screen newborns for dozens of genetic diseases and immediately know which diets to avoid giving them or which medications to begin early. Physicians are using genetic markers to better tailor therapies to individual patients. We are certainly entering a new era.

How dengue virus enters cells found

Scientists have unveiled the mechanism behind how dengue enters cells of our immune system, a finding that could help develop vaccine for the deadly virus. 

Dengue fever, an infectious tropical disease caused by a mosquito-borne virus, afflicts millions of people each year, causing fever, headache, muscle and joint pains and a characteristic skin rash, researchers said. In some people the disease progresses to a severe, often fatal, form known as dengue hemorrhagic fever.

Liquid Crystal Soft Matter Improves Biosensing

Plop living, swimming bacteria into a novel water-based, nontoxic liquid crystal and a new physics takes over. The dynamic interaction of the bacteria with the liquid crystal creates a novel form of soft matter: living liquid crystal.
