They want to prevent or reverse atherosclerosis by removing a harmful lipid known as 7-ketocholesterol (7KC) from the arterial walls.
Underdog has a molecule that can extract the oxidized waste from the body. It is a variant of cyclodextrin which is an existing drug that is already approved by the FDA and has a good safety profile.
In microbiology, an electroporator is a tool that allows scientists to apply electricity to a cell to temporarily breach its cell wall so you can introduce chemicals, drugs or DNA to the cell. These tools are extremely useful in the lab, but they’re also very expensive. They cost anywhere from roughly $3,000 to $10,000.
Researchers at Georgia Tech just revealed they’ve found a way to create an electroporator that costs next to nothing to make. Their research was just published in the journal PLOS Biology.
These researchers were able to create a version of the electroporator that can generate short bursts of more than 2,000 volts of electricity, which they named the “ElectroPen,” using a crystal from a common lighter, copper-plated wire, heat-shrinking wire insulator and aluminum tape. They then created a case for these components using a 3D printer. They claim you can assemble it within 15 minutes once you have all the pieces.

Researchers at the University of South Florida have discovered a novel feedback pathway from the brain to the eye that modulates eye pressure – a significant advancement in the effort to diagnose and treat glaucoma. Glaucoma is associated with increased pressure in the eye due to a reduce ability of the eye to maintain proper fluid drainage. The heightened pressure applies mechanical strain to the optic nerve as the nerve exits the eye, resulting in vision loss and potential blindness.
It has long been hypothesized that brain pressure might also play a role in glaucoma because the amount of strain on the optic nerve depends not just on eye pressure, but the difference in pressure between the eye and brain. The groundbreaking study published in the Journal of Physiology shows, for the first time, that eye and brain pressure are physiologically connected. The neuroscientists came to this conclusion by altering brain pressure in animal models and noting changes in the fluid drainage properties of the eye that could be blocked by chemicals that eliminate feedback signals from the brain. Interestingly, the eye’s ability to clear fluid changed in a manner that restored a healthy pressure difference across the optic nerve.
“The drainage control system may service to protect the optic nerve from swings in eye or brain pressure,” said Chris Passaglia, PhD, professor in the USF Department of Medical Engineering. “Its discovery offers a new target for glaucoma treatment, wherein the modulatory mechanisms of the system might be exploited to help lower eye pressure and impede disease progression in glaucoma patients.”
Tooth loss is a concern that most people will face at some point in their life. According to studies, by the age of 74, 26 percent of adults will have lost all of their permanent teeth. Dentures are sufficient, but they’re uncomfortable and dental implants can fail and have no ability to “remodel” as the surrounding jaw bone changes with age.
All of these are reasons why some people have placed their hope in stem cell research. While there are controversy surrounds the new medical method such as the use and destruction of human embryos, not all research involves human tissue and has the potential to change a lot of lives.
A new technique being tested in the Tissue Engineering and Regenerative Medicine Laboratory of Dr. Jeremy Mao, Edward V. Zegarelli prof of odontology, and a professor of biomedical engineering at Columbia University, could make “tooth loss” a thing of the past. The cluster believes they need to find some ways to own the body’s stem cells, migrate it to a three-dimensional scaffold manufactured from natural material and insert it to a patient’s mouth.
ANN ARBOR, Mich. — Given the option, would you avoid the gym altogether and simply pop a pill or drink a supplement that brings about the same benefits as a workout? It sounds farfetched, but the idea of lounging around all day yet still enjoying the health benefits of an intense workout may soon be possible. While there are still many details to be worked out, researchers at the University of Michigan say that the naturally occurring protein Sestrin appears to mimic the effects of exercise on both flies and mice in experimental trials.
These findings could have far reaching implications across the fitness, medical, and scientific fields. For instance, Sestrin could conceivably help individuals unable to work out due to old age or health problems maintain their muscles.
“Researchers have previously observed that Sestrin accumulates in muscle following exercise,” explains Myungjin Kim, Ph.D., a research assistant professor in the Department of Molecular & Integrative Physiology, in a release.
Brain cancer remains challenging to diagnose, due to nonspecific symptoms and a lack of cost-effective tests. A new blood test that uses attenuated total reflection (ATR)-Fourier transform infrared (FTIR) spectroscopy in conjunction with machine learning technology, may help advance the detection of brain cancer.
The patented technology, developed by a team at the University of Strathclyde, uses infrared light to produce a “bio-signature” of a blood sample and applies artificial intelligence to check for the signs of cancer.
The research is published in Nature Communications in a paper titled, “Development of high-throughput ATR-FTIR technology for rapid triage of brain cancer.”
Researchers foresee myriad benefits for humanity, but also acknowledge ethical issues.
RIO DE JANEIRO, BRAZIL — Approved in Brazil almost four years ago, the colon capsule is finally starting to become popular and available in laboratories and diagnostic centers.
The capsule serves as an alternative to traditional colonoscopy, where a wired camera is introduced through the anus and guided throughout the large intestine.
“The new technology is less invasive and does not require sedation,” says Dr. Admar Borges, of the Brazilian Society of Digestive Endoscopy.
Researchers from the University Hospital and ETH Zurich have developed a machine that repairs injured human livers and keep them alive outside the body for one week. This breakthrough may increase the number of available organs for transplantation saving many lives of patients with severe liver diseases or cancer.
