Does giving a placebo require lying to a patient? This study concludes...no! Placebos still work even when the patient knows, at least for emotional distress.

What do gene sequencing, catching criminals with DNA evidence, and “designer babies” all have in common? Forty years ago, these were all considered science fiction topics. Today, they are fields of serious study. All three of these fields, and many more, were made possible by a very important discovery in 1986: a…

Laboratory methods behind the polio vaccine discovery In 1949, Harvard scientists established a few tissue culture tricks that not only allowed Jonas Salk to develop the polio vaccine, but also became standard practice when growing polio in the lab. His team was awarded a Nobel Prize.

Poliomyelitis is the name of the disease caused by the poliovirus, and it mostly affects children under the age of 5, causing paralysis in a small percent of cases. The disease had been around since the 1800s at low levels, but became an epidemic in multiple countries between the 1910s-1960s. Because polio was killing…

Can a Chinese medicinal herb Psoralea fructus build healthy bones? Corylin, a flavonoid molecule derived from a Chinese medicinal herb, is effective in stimulating the body to make osteoblasts, which are cells that form new bones.

Osteoblasts are cells that are responsible for bone formation. A lack of osteoblasts will cause osteoporosis – a disease that occurs when the body has too little bone. The current treatments for osteoporosis either slow down bone resorption, or promote the growth of osteoblasts. However, these treatments are often…
