“A healthy mind in a health body.” It’s a saying that is often tossed around when discussing the link between exercise and brain health. Many studies have shown that exercise can improve cognitive performance. In a new study, researchers asked if body strength could be used to predict brain health. Hand grip strength has been used in a variety of studies to assess cardiovascular health, … Continue reading What does your grip strength say about your mental health?
Despite all of the amazing discoveries science has made, we are still trying to understand the human body. For example, this time last year, scientists defined a new human organ, the mesentery. Now, scientists might finally have an answer to why prolonged periods of sitting are linked to increased fat storage. Humans might have a mechanism that acts as internal weight scale. Scientists probed this … Continue reading In a sitting culture, our bones could be responsible for obesity
Ever wonder why we make snot? Mucus lines our respiratory and gastrointestinal tracts, acting as a sticky glue that traps unwanted substances before they can get into the body. However, research from Jeremy Barr’s lab in Melbourne, Australia has shown that there might be a lot more to the story of snot. Barr and his team have found that mucus contains a far higher concentration … Continue reading Bacteria-killing viruses: an army of disease-fighters within us?
Developing cancer drugs is challenging. Often, scientists will find a drug that kills cancer cells in a petri dish but fails to act on an actual tumor. Ravid Straussman from the Weizmann Institute of Science and Todd Golub from Harvard Medical School think that in situ, bacteria can protect cancer cells from drugs. To test their theory, Staussman and Golub mixed some healthy skin cells with cells from a … Continue reading Bacteria May Help Protect Cancer Cells
Tattoos are often whimsical, traditional, beautiful—but can they also be medical? The Dermal Abyss project, a collaboration of researchers at Harvard and MIT, is trying to develop a tattoo that can monitor an individual’s health. They have already created “bio-ink” capable of fluorescing at different colors in response to certain variables in the body. In theory, a diabetic inked with one of these tattoos would … Continue reading Harvard and MIT are making tattoos to monitor your health
Over 17,000 Americans are currently waiting for liver transplants, with millions more living with chronic liver disease. There simply aren’t enough healthy organs to go around. So why not engineer them? Growing a liver “from scratch” by using its constituent cells could replace the need for whole organ transplants. Researchers at the Massachusetts Institute of Technology generated hydrogels containing three different types of human cells, … Continue reading From Seed to Organ: Growing a Liver
A medical team at Johns Hopkins University genetically engineered a common cold virus to deposit a gene when injected into the human eye. This gene codes for a protein that binds to VEGF, another protein whose activity in old age contributes to vision loss (a disease called AMD or wet AMD). This small clinical study’s preliminary results show that just one small dose is potent enough to improve a patient’s vision loss. Continue reading Genetically engineered viruses: a medicine of the future
