TED: The brain may be able to repair itself — with help | Jocelyne Bloch

Through treating everything from strokes to car accident traumas, neurosurgeon Jocelyne Bloch knows the brain’s inability to repair itself all too well. But now, she suggests, she and her colleagues may have found the key to neural repair: Doublecortin-positive cells. Similar to stem cells, they are extremely adaptable and, when extracted from a brain, cultured …

American Museum of Natural History: SciCafe: Mending a Broken Heart

How can doctors repair damaged cardiac tissue while the heart still beats and pumps blood? Join stem cell researcher Jeffrey Karp to understand how scientists are drawing inspiration from nature to solve medical problems in new and exciting ways.  

Harvard University: ‘Lifespan Machine’ Probes Cause of Aging

Researchers in the lab of Walter Fontana, Harvard Medical School professor of systems biology, have found a surprising statistical regularity in how a variety of genetic and environmental factors affect the life span of the C. elegans worm. Their findings suggest that aging does not have a single discrete molecular cause but is rather a …

Harvard University: Visualizing cancer’s origins from the first affected cell

Researchers at Harvard-affiliated Boston Children’s Hospital have, for the first time, visualized the origins of cancer from the first affected cell and watched its spread in a live animal. Their work, published in the Jan. 29 issue of Science, could change the way scientists understand melanoma and other cancers and lead to new, early treatments …

Lund University: New method detects more breast cancer in screening

Tomosynthesis detects 40% more breast cancers than traditional mammography does, according to a major screening study from Lund University, Sweden. This is the first large-scale study to compare the screening method with regular mammograms. The 3D X-ray technique is also more comfortable for women, as breast compression is halved.  

Massachusetts Institute of Technology: Tracing a cellular family tree

By combining sophisticated RNA sequencing technology with a new device that isolates single cells and their progeny, MIT researchers can now trace detailed family histories for several generations of cells descended from one “ancestor.” This technique could shed light on how cancer develops.  

Stanford University: Cafe Scientifique: Immunotherapy for Cancer

Edgar Engleman, MD, Professor of Pathology and of Medicine at Stanford University, Stanford Blood Center Founder and Medical Director. A new era has begun when it comes to the treatment of cancer. In the past, we have been unable to mobilize the immune system of patients with cancer, but now we can! Learn why this …

TED-Ed: How stress affects your brain – Madhumita Murgia

Stress isn’t always a bad thing; it can be handy for a burst of extra energy and focus, like when you’re playing a competitive sport or have to speak in public. But when it’s continuous, it actually begins to change your brain. Madhumita Murgia shows how chronic stress can affect brain size, its structure, and …

Texas A&M University: Painless, Continuous Monitoring of Diabetes

Biomedical engineers at Texas A&M University are creating a tiny biosensor with a self-cleaning membrane for doctors to plant under the skin of people with diabetes. When inserted along the inner forearm, the biosensor would send data about the levels of glucose in a patient’s bloodstream to a device that the researchers envision as being …

TED: Alzheimer’s Is Not Normal Aging — And We Can Cure It | Samuel Cohen

More than 40 million people worldwide suffer from Alzheimer’s disease, and that number is expected to increase drastically in the coming years. But no real progress has been made in the fight against the disease since its classification more than 100 years ago. Scientist Samuel Cohen shares a new breakthrough in Alzheimer’s research from his …

TED-Ed: What happens when your DNA is damaged?

The DNA in just one of your cells gets damaged tens of thousands of times per day. Because DNA provides the blueprint for the proteins your cells need to function, this damage can cause serious issues—including cancer. Fortunately, your cells have ways of fixing most of these problems, most of the time. Monica Menesini details …

Nature: Tumour immunology and immunotherapy

This animation created by Nature Reviews Cancer and Nature Reviews Immunology illustrates how tumour cells are sensed and destroyed by cells of the immune system and how tumours can evolve to evade immune-mediated elimination. Scientists are developing new immunotherapies that help the immune system to ‘fight back’ — the animation explains how these exciting new …
