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…
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.
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, it may become overly active and attack healthy body cells,…
In a study conducted by Taiwanese scientists with female college students, they showed that internet addiction has a negative impact on sleep quality.
A team of scientists has made valves which can operate on tiny channels of fluid the width of 3 human hairs! This paper, published in the Journal of Biomedical Microdevices, represents a step forward in lab technology. Creating a tiny valve like this could have important implications for cancer research, where fluids…
Obesity and abnormal liver function have been predicted to play a part in extended hospitalization duration and worsen the health conditions of COVID-19 patients.
Guanine, a component of DNA, is revealed to react with oxygen and change how your genes are expressed.
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.
Parkinson’s disease is a progressive neurodegenerative disease, meaning that brain cells will continuously die off as the illness persists. The brain cells that are mainly affected in Parkinson’s disease are ones that produce dopamine, a chemical in the brain that is known to be important in the control of the…
Scientists injected the herpes-simplex virus type 1, the strain that causes cold sores, into brain tissue and found that it caused the brain to look and act like an Alzheimer’s brain. Injecting an antiviral drug was successful in reducing the spread of herpes infection and brain damage.
