The patient, a man in his 70s with a shock of silver hair, lies in the neuro intensive care unit (neuro ICU) at Yale New Haven Hospital. Looking at him, you’d never know that a few days earlier a tumor was removed from his pituitary gland. The operation didn’t leave a mark because, as is standard, surgeons reached the tumor through his nose. He chats cheerfully with a pair of research associates who have come to check his progress with a new and potentially revolutionary device they are testing.

Stem Cells for Cell-Based Therapies
The world of stem cells
We know the human body comprises many cell types (e.g., blood cells, skin cells, cervical cells), but we often forget to appreciate that all of these different cell types arose from a single cell—the fertilized egg. A host of sequential, awe-inspiring events occur between the fertilization of an egg and the formation of a new individual:
Embryonic stem (ES) cells are also called totipotent cells.
The first steps involve making more cells by simple cell division: one cell becomes two cells; two cells become four cells, etc.
Each cell of early development is undifferentiated; that is, it is...

Why acupuncture is giving sceptics the needle
Acupuncture has been prescribed by half of Britain's doctors, but after 3,000 clinical trials its efficacy remains unproven. So is the NHS making a grave error in supporting this ancient treatment?• Are vitamin pills a sham? Q&A with Dr. Paul OffitYou can't get crystal healing on the NHS. The Department of Health doesn't fund faith healing. And most doctors believe magnets are best stuck on fridges, not patients. But ask for a treatment in which an expert examines your tongue, smells your skin and tries to unblock the flow of life force running through your body with needles and the NHS will be happy to oblige.The govern...

Do No Harm: Stories of Life, Death and Brain Surgery review
Patients see neurosurgeons as gods, but what is the reality? Henry Marsh has written a memoir of startling candourWe go to doctors for help and healing; we don't expect them to make us worse. Most people know the aphorism taught to medical students, attributed to the ancient Greek Hippocrates but timeless in its quiet sanity: "First, do no harm." But many medical treatments do cause harm: learning how to navigate the risks of drug therapies, as well as the catastrophic consequences of botched or inadvised surgical operations, is a big part of why training doctors takes so long. Even the simplest of therapies carries the ri...

Neuroscientist Discusses the Idea of Consciousness Transfer From the New Movie Self/less
A new thriller starring Ben Kingsley and Ryan Reynolds explores the idea of transferring consciousness from one body to another. Unlike Freaky Friday, or the myriad of other family movies and comedies that have explored the idea, this one actually explores the science of the process. In the movie Self/less, a rich business man (Kingsley) is dying of cancer. However, he is able to prolong his "self" by transferring his consciousness from one body to another using a medical procedure called "shedding." You may be wondering how such a far-out concept can actually have any science to it. I wondered the same thing, so I asked ...

The Man Who Grew Eyes
The train line from mainland Kobe is a marvel of urban transportation. Opened in 1981, Japan’s first driverless, fully automated train pulls out of Sannomiya station, guided smoothly along elevated tracks that stand precariously over the bustling city streets below, across the bay to the Port Island. The island, and much of the city, was razed to the ground in the Great Hanshin Earthquake of 1995 – which killed more than 5,000 people and destroyed more than 100,000 of Kobe’s buildings – and built anew in subsequent years. As the train proceeds, the landscape fills with skyscrapers. The Rokkō mounta...

2016 Moon Shot for Cancer: Focus on Prevention
It is now 2016, and Americans hope for a brighter, healthier new year. Are Americans healthier today than they were last year or the year before? Will there be fewer people diagnosed with cancer? According to the American Cancer Society, it is projected that in 2016 there will be 1,685,210 new cancer cases and 595,690 deaths due to cancer. This is an increase over previous years. While it is true that the death rate for several cancers has decreased (due mostly to better screening and earlier diagnosis), it is also true that several cancers are on the rise, including cancers of the thyroid, liver, pancreas, kidney, small i...

Medical Research: The Best Investment We Can Make in Our Future
While the cure for cancer has been elusive, President Obama's National Cancer Moonshot initiative offers renewed hope that we could see breakthroughs in prevention, detection, and treatment for a disease that affects millions of Americans and their families. The cancer moonshot is the latest demonstration that Washington understands the potential for medical research to change lives and improve the health of all Americans. It builds on the bipartisan support we saw last fall when House and Senate negotiators agreed on a $2 billion budget increase for medical research through the National Institutes of Health (NIH). Today,...

Toxic Air – The ‘Invisible Killer’ that Stifles 300 Million Children

Neurological Diseases Cost The U.S. $800 Billion Each Year
Over 100 million Americans ― close to a third of the total population ― suffer from neurological diseases such as Alzheimer’s, multiple sclerosis, migraines, epilepsy and spinal cord injury.
These conditions put an enormous financial strain on the health care system, totaling nearly $800 billion in annual costs, according to a new report published in the journal Annals of Neurology. To put that into perspective, the figure exceeds the U.S. military budget by over $100 billion.
That number reflects the total cost of the nine most common neurological diseases, but the total costs related to th...
