Biochemistry involves studying the chemistry of living things such as substances, compounds and processes. Biochemists combine the fields of microbiology, cell biology, genetics, chemistry, cell biology, and physics in their day-to-day work or experiments. They get into the most, minute characteristics of organisms, and their biological processes. They may be identifying the way in which DNA, which carries the genetic information, is

Breast Cancer: Where It Starts
Unfortunately, signs of breast cancer are rarely visible from the surface of the skin. Breast self-exams should be done regularly to detect physically substantial lumps under the skin. But even self-exams may miss some cases. By moving the slide from left to right, you will see where (in most cases) breast cancer develops: deep down in the inner structures of the breast, within the ducts.
Cellular Abnormalities & Cancer
Cancer begins deep down in the body, at the cellular level. Cells are the basic building

Thanks to the work of our sympathetic nervous system, the "fight or flight" system that takes over when we're stressed, when you see your boss's name in your inbox late at night, your body reacts like there's a lion on the loose.
Behind the wide range of both physical and mental reactions to stress are a number of hormones that are in charge of adding fuel to the fire.
Commonly known as , it is produced by the adrenal glands after receiving a message from the brain that a stressful situation has presented itself.
Adrenaline, along with norepinephrine (more on that below), is largely

Diabetes could be cured after scientists discovered that toxic clumps of a hormone stop cells producing insulin.
Scientists at Manchester University have found that both Type 1 and Type 2 diabetes are driven by the same underlying mechanism.

The current Ebola Virus outbreak began in Guinea in December 2013. This outbreak now involves transmission in Guinea, Liberia, Nigeria, and Sierra Leone. As of 4 August 2014, countries have reported 1 711 cases (1 070 confirmed, 436 probable, 205 suspect), including 932 deaths. This is currently the largest EVD outbreak ever recorded. And on 8 August 2014, WHO declared the Ebola outbreak in West Africa a Public Health Emergency of International Concern.
Epidemiological facts and experience
- The incubation period of Ebola virus disease (EVD) varies from 2 to 21 days. Person-to-person transmission by means of direct contact with infected persons or their body fluids/secretions is considered the principal mode of transmission. In a household study, secondary transmission took
