Twelve native Australian fruits that are exceptional sources of antioxidants have been identified in research published in the journal Innovative Food Science & Emerging Technologies.
Can a genetic signature identify the origin of a human stem cell line? Scientists report that a widely available method for comprehensive genetic analysis can help distinguish the type of human embryo that stem cells come from.
Ionizing radiation, toxic chemicals, and other agents continually damage the body’s DNA, threatening life and health: unrepaired DNA can lead to mutations, which in turn can lead to diseases like cancer. Intricate DNA repair mechanisms in the cells’ nuclei are constantly working to fix what’s broken, but whether the repair work happens “on the road” ? right where the damage occurs ? or “in the shop” ? at specific regions of the nucleus ? is an unanswered question.
A new fingerprinting technique could potentially detect the diet, race and sex of a suspected criminal, according to new research published in the August edition of the journal Analytical Chemistry.
Asthma affects 300 million people worldwide and, according to World Health Organization, it killed 255 000 people in 2005. Asthma attacks are caused by an acute inflammatory reaction in the airways, a reaction that is largely due to actions of LTC4 synthase (an enzyme which catalyzes a synthesis process). For this reason asthma medicines often aim to block the downstream effects of LTC4 synthase.
