Dried plums may protect astronaut’s bones from radiation damage In a mouse study, researchers from NASA Ames Research Center have demonstrated that compounds in plums may protect bones from radiation damage.

Dried plums outperformed some medications in a bone health study (in mice) at NASA Ames.

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 READ MORE

Scientists debunk what we knew about sperm movement New research finds we were looking at sperm all wrong. For 350 years, scientists believed sperm wiggled their tails side-by-side to create a whip-like motion. Using 3D technology, a study found sperm actually move by rolling around and spinning their heads like tops.

New treatment for rheumatoid arthritis shows great promise Researchers find that an antibody called m909 is able to eliminate cells causing inflammation in rheumatoid arthritis and in many other autoimmune diseases.

The immune system is your body’s personal army of soldiers — when it comes across potentially harmful invaders like viruses and bacteria, it will flag those invaders for destruction. However, this defense system is not always perfect. In some cases, READ MORE

Spend a lot of time online? It may affect your sleep. In a study conducted by Taiwanese scientists with female college students, they showed that internet addiction has a negative impact on sleep quality.

This new tiny biomedical device makes diagnosing cancer types easier A team of scientists has made valves which can operate on tiny channels of fluid the width of 3 human hairs. It can deliver colored stains to tissue samples accurately, so that scientists can view cancer cells under the microscope more easily.

One way that oxygen can damage our DNA Guanine, a component of DNA, reacts with oxygen and changes how some of your genes are expressed.

Guanine, a component of DNA, is revealed to react with oxygen and change how your genes are expressed.

Nationwide study reveals the deadly impact of the coronavirus on cancer patients In a study of 2,000 cancer patients, hydroxychloroquine showed no clinical benefit. Remdesivir was associated with a lower mortality risk but only certain groups of patients had access to it. Cancer patients also showed a higher risk of dying within 30 days of receiving a coronavirus diagnosis.
