Black silicon prevents eye implant from gumming up

A team of researchers led by Caltech’s Hyuck Choo has developed an eye implant for glaucoma patients that could one day lead to more timely and effective treatment.

If you have ever been to an ophthalmologist, you have probably had your checked: with your chin resting on a support to keep your head still, the doctor applies pressure to your eye either via a puff of warm air or by gently pressing a probe against the eye’s . By measuring the amount that surface deforms as a result of a known amount of pressure, the ophthalmologist can calculate a rough estimate of the intraocular pressure.

While effective enough for routine eye exams, the technique is not sufficient for patients suffering from glaucoma. Glaucoma affects more than 2 million people in the United States, and is the second leading cause of blindness after cataracts. It is actually a family of eye diseases that are characterized by an increase in the pressure of the fluid inside the eye. That pressure damages the optic nerve at the back of the eye.

Computers create recipe for two new magnetic materials

Material scientists have predicted and built two new magnetic materials, atom-by-atom, using high-throughput computational models. The success marks a new era for the large-scale design of new magnetic materials at unprecedented speed.

Although magnets abound in everyday life, they are actually rarities—only about five percent of known inorganic compounds show even a hint of . And of those, just a few dozen are useful in real-world applications because of variability in properties such as effective temperature range and magnetic permanence.

The relative scarcity of these can make them expensive or difficult to obtain, leading many to search for new options given how important magnets are in applications ranging from motors to (MRI) machines. The traditional process involves little more than trial and error, as researchers produce different molecular structures in hopes of finding one with magnetic properties. Many high-performance magnets, however, are singular oddities among physical and chemical trends that defy intuition.

A new CRISPR breakthrough could lead to simpler, cheaper disease diagnosis

The controversial laboratory tool known as CRISPR may have found a whole new world to conquer. Already the favored method of editing genes, CRISPR could soon become a low-cost diagnostic tool that could be used practically anywhere to determine if someone has an infectious disease such as Zika or dengue.

The controversial gene-editing tool may be able to identify infections reliably for pennies in places without electricity.

Toyota shows robotic leg brace to help paralyzed people walk

Toyota is introducing a wearable robotic leg brace designed to help partially paralyzed people walk.

The Welwalk WW-1000 system is made up of a motorized mechanical frame that fits on a person’s leg from the knee down. The patients can practice walking wearing the robotic device on a special treadmill that can support their weight.

Toyota Motor Corp. demonstrated the equipment for reporters at its Tokyo headquarters on Wednesday.

Star Trek’s Tricorder Now Officially Exists Thanks To A Global Competition

Oscar Wilde once said that life imitates art, and science and engineering is often no exception to this. Science fiction certainly provides science types with plenty of inspiration for inventions, including holograms, teleportation, and even sonic screwdrivers.

Star Trek’s all-purpose medical device, the Tricorder, has also inspired a fair few people to recreate its near-magical ability to instantly diagnose a patient. As it happens, the non-profit X-Prize Foundation were so keen to get one invented that they started a global competition to see if any mavericks would succeed.

Rather remarkably, one team has emerged victorious in their endeavor. A family-led team from Pennsylvania, appropriately named Final Frontier Medical Devices, have bagged themselves a sum of $2.5 million, with a second-place prize of $1 million going to the Taiwan-based Dynamical Biomarkers Group.

New pill considered key in the fight against ageing

This contains information that is not in other articles on the same topic of David Sinclair:

“The results certainly sound encouraging. Before he started taking a 500mg NMN pill every morning, 47-year-old Professor Sinclair had his blood tested and was told his body had a biological age of 58.

After consuming NMN for three months, he was tested again and his biological age was 32.”

Synopsis: A Room-Sized Linear Accelerator for Proton Therapy

A proton beam can kill cancer cells, and the accelerators used for treatment are always the circular kind. Linear accelerators (“linacs”) allow more control of the beam; for example, the energy can be varied rapidly to match a patient’s breathing. But linacs take up a lot of space. Now researchers propose a design that could fit in a room 10 m x 20 m, potentially making linacs practical for patient therapy. Research from CERN.

Climate change, other concerns fuel scientists’ in-your-face activism

While many scientists have shied away from explicitly political actions in recent decades, the community throughout history has spoken publicly on a wide variety of social, technological and ideological issues.

That has included everything from opposing fascism, nuclear proliferation and the Vietnam War to sitting on government panels that advise elected leaders on stem-cell research involving human embryos.

In U.S. history, scientists have been vocal about fascism, nuclear proliferation, the Vietnam War, stem cells and more.

New Artificial Organ Can Be Implanted in the Body to Create Cancer-Fighting Cells

  • Researchers at UCLA have created an artificial thymic organoid that generates its own cancer-fighting T cells.
  • While it has not been tested in humans yet, this artificial organ could reduce the time and cost of T cell immunotherapy and make it a more viable option for patients with low white-blood cell counts.

Many artificial organs are being developed as an alternative to donated organs, which are only temporary solutions that require the recipients to maintain a lifetime regiment of medications. With recent advancements in biomedical technologies, the time may be coming when those who require transplants no longer need to wait on donation lists to replace organs like kidneys and blood vessels. And now, scientists have added the thymus to the list of body parts we can artificially simulate.

The thymus is a gland that is essential to your immune system. T cells, a type of white blood cell that helps to get rid of viruses, bacterial infections, and cancer cells, mature within this gland. When people get sick (or as they age), the thymus becomes worse at its job. In some cases, people with different types of cancer are not getting the biological support and help they need from their T cells.
