While many high-school sophomores are busy partying and socializing, Jack Andraka developed a test for pancreatic cancer that is the first test that detects the disease and tumors before they get out of hand.

And with pancreatic cancer having the lowest survival rate of any cancer, he truly accomplished something amazing with his work.

Pancreatic cancer shows no symptoms in the early stages and affects more than 8,000 people each year in the Uk and 45,000 in the U.S. Due to poor testing procedures in the past, by the time the cancer is detected, 4 out of 5 people are inoperable.

Questionable startups are claiming to be able to determine how smart a frozen IVF embryo will become if carried to term, and parents are taking the bait.

Genomic Prediction, the most prominent of these companies, offers tests to scan embryos for genetic diseases and other conditions — as well as genetic indicators that a future child will be in the bottom two percent of intelligence.

And MIT Technology Review reports that Genomic Prediction co-founder Stephen Hsu often uses media appearances to discuss future plans for a general intelligence test — something that, with current tech, is extremely unlikely to actually work.

Abstract: We know that creatures like us have two separate systems for processing information, the genome and the brain. We know that the genome is digital, and we can accurately transcribe our genomes onto digital machines. We cannot transcribe our brains, and the processing of information in our brains is still a great mystery. I will be talking about real brains and real people, asking a question that will have practical consequences when we are able to answer it. I am not able to answer it now. All I can do is to examine the evidence and explain why I consider it probable that the answer will be that brains are analog.

Prof Freeman Dyson | “Are Brains Analogue or Digital?” | 19th May 2014 — Dublin Institute for Advanced Studies, Statutory Public Lecture of the School of Theoretical Physics, in association with the UCD School of Physics.

City of Hope researchers may have found a way to sharpen the fastest, cheapest and most accurate gene editing technique, CRISPR-Cas9, so that it can more successfully cut out undesirable genetic information.

This improved cutting ability could one day fast-track potential therapies for HIV, and, potentially, other immune conditions.

“Our CRISPR-Cas9 design may be the difference between trying to cut a ribeye steak with a butter knife versus slicing it with a steak knife,” said Tristan Scott, Ph.D., lead author of the study and a staff research scientist at City of Hope’s Center for Gene Therapy. “Other scientists have tried to improve CRISPR cutting through chemical modifications, but that’s an expensive process and is like diamond-coating a blade. Instead, we have designed a better pair of scissors you can buy at any convenience store.”

The Department of Defense has awarded Dr. Gour Pati, professor of Physics and Engineering at Delaware State University a $239,908 grant from the U.S. Army to develop and build a millimeter-wave quantum sensing system at DSU.

Dr. Pati – the principal investigator – and his researchers have recognized the increasing importance of millimeter-wave sensing and imaging in commercial and military sectors, as well as how it is driving the development of low-cost sensors. Dr. Pati’s success in winning the DoD grant engages DSU scientists and students in the work of furthering this advancement.

Rydberg atoms have a hypersensitive response to microwave, millimeter-wave and terahertz radiation. They have the potential for applications in modern communications, remote sensing and many other fields, including medical science. Pati and his team will develop a real-time millimeter-wave sensor using laser-induced fluorescence in Rydberg atoms.

Gene therapy has traditionally been applied to well-understood diseases where a single genetic mutation was to blame. A new generation of technology is expanding the potential of gene therapy to treat conditions that were previously unreachable. Since the first gene therapy clinical trials in the 1990s, the technology has made its way into the market for conditions ranging from blindness to cancer. Gene therapy has the potential to fix any genetic mutation causing disease by inserting a new copy of the faulty gene. However, its reach has historically been limited. We’ve been constrained with the things we.

David A. Sinclair, PhD, is a professor in the Department of Genetics at Harvard Medical School and co-director of the Paul F. Glenn Center for the Biological Mechanisms of Aging.
Dr. Sinclair’s work focuses on understanding the mechanisms that drive human aging and identifying ways to slow or reverse aging’s effects. In particular, he has examined the role of sirtuins in disease and aging, with special emphasis on how sirtuin activity is modulated by compounds produced by the body as well as those consumed in the diet, such as resveratrol. His work has implications for human metabolism, mitochondrial and neurological health, and cancer.
