An NIH-funded study shows our thoughts can manipulate computer images |
Remember “The Matrix” movies? Characters in them are connected to a cyber world through a rod jammed into the backs of their heads. The cyber world can be influenced by thoughts and beliefs. The lead character, Neo, has to believe he’s “The One” so he can have the super powers needed to free humanity from the machines. Such science fiction technologies once seemed impossible, but not so much any more.
In an NIH-funded study at UCLA Medical Center, Itzhak Fried and his colleagues showed that humans can regulate their neurons to alter a cyber reality, while being subjected to competitive stimuli. They worked with patients being treated for intractable epilepsy who’d had wires implanted into their brains. After connecting the wires to a computer, subjects were shown two merged images on a computer screen. With focused attention, they were able to force the computer to display one image and discard the other.
The brain-computer interface helps scientists understand how the brain processes information and how thoughts and decisions affect cell activity. The potential applications of the research are wide-ranging and could help paralyzed individuals communicate or control prosthetic limbs.
The results leave me wondering what’s next for our high-tech civilization.

For the Intel Science Talent Search (STS) competition this year, 300 semifinalists were chosen from among 1,736 entrants from high schools in 37 states and the District of Columbia. Each semifinalist received a $1,000 award for their research, and $1,000 was given to their school to further excellence in science, math, and engineering education. |
The 40 finalists were named January 27, and the final judging process will be completed March 11 through 16 at the Science Talent Institute in Washington, D.C. The winner receives a scholarship award of $100,000.
Alumni of the Intel STS have made extraordinary contributions to science and hold more then 100 of the world’s most coveted science and math honors, including seven Nobel Prizes and three National Medals of Science.
This year, researchers in National Institutes of Health (NIH) laboratories mentored several of the semifinalists and one finalist:
- Lijin Dong, Ph.D., mentored finalist Yifan Li at the Genetic Engineering Facility in the National Eye Institute, NIH.
- Paul Liu, M.D., Ph.D., mentored semifinalist Pin-Joe Ko at the National Human Genome Research Institute (NHGRI), NIH.
- Charles Venditti, M.D., Ph.D., and Laura Elnishi, Ph.D., co-mentored semifinalist Conway Xu, also at NHGRI.
- Anelia Horvath, Ph.D., mentored semifinalist Kristen Knutsen Rosano at the National Institute of Child Health and Human Development, NIH.
NIH researchers and their mentees are enthusiastic about each other and their experiences together. Dr. Horvath says that Kristen is a brilliant student with impressive experience and knowledge in molecular biology and she was “perfectly matched with our lab.”
Dr. Venditti says that Conway contacted him after reading some of his lab’s papers on the NHGRI Web site. Conway’s experience opened his eyes to the world of medical research and how it is closely tied to the clinical aspects of medicine.
Lijin Dong said that Yifan came to the lab just like most high school students who have not been exposed much to the lab environment. “I worked with him on a daily basis by assigning readings, having discussions on the papers, and working through the logic of the project and lab skills,” he says.
I asked Yifan to explain his project so that other students would understand his work. He said, “Our project’s aim is to contribute to helping people who suffer from blindness -- in particular, age-related macular degeneration (AMD), a common retinal disease,- that leads to visual impairment. “
Yifan stimulated embryonic stem cell s to grow into a type of eye cell whose deterioration is heavily associated with AMD. With the continued succes s of stem cell research, he believes that “we may see a burst of transplantation studies in the future that could lead to medical advances in curing retinal disease. “
When I asked how he’s preparing for the final competition, Yifan said that he’s getting a poster ready for his presentation during the conference and learning as much as possible about retinal development, retinal disease, and the progression of stem cell research. “I want to be able to field any question from any judge competently and confidently, so that’s going to take a lot of preparation,“ he said.

When we’re healthy, there’s plenty of oxygen in the air to keep us happy and active (unless, of course, we’re at the top of Mount Everest). But after some injuries, a boost of oxygen in our tissues can be very helpful. That’s where HBOT comes in.|
HBOT, or hyperbaric oxygen therapy, is the delivery of oxygen under high pressure. In HBOT, patients are placed in a chamber where the pressure is a few times that found at sea level. They then breathe oxygen-enriched air that’s either in the chamber or supplied through a mask. HBOT therapy is coming back into vogue in large part because we have the technology to build better and much safer chambers. (They used to have a tendency to explode.) HBOT chambers are being used in clinics all over the country.
The first use of HBOT was to treat scuba divers with “the bends.” The bends happens when divers surface too quickly. The high pressure underwater allows more gas to dissolve in the blood and tissues than can on land. As divers return to the surface from below, the gas comes out of solution. When divers surface slowly, the gas is released gradually, but if they come up too quickly, it’s released suddenly, sort of like what happens when we open a can of soda pop. Air bubbles form in tissues, which is painful and sometimes even deadly. So, divers with the bends are usually rushed to hyperbaric chambers, where their blood and tissues can reabsorb the gas temporarily. The pressure in the chamber is then decreased gradually, just like it is when divers surface slowly.
OK, but what does this have to do with healing? Well, many wounds — especially in people with diabetes and skin grafts — don’t have a good blood supply. That means the tissue lacks oxygen, and oxygen is needed for good healing. One way to increase tissue oxygen is to send patients scuba diving, but I’m not sure my grandmother with diabetes would be keen on that. Instead, doctors use HBOT. Patients hang out in an HBOT chamber for a few hours at a time to get extra oxygen into their tissues to help their wounds heal.
There are numerous other clinical indications for HBOT therapy that have been approved by the Food and Drug Administration. A number of clinical trials looking at HBOT use for traumatic brain injury, diabetic ulcers, and burns are now underway.

Probably everyone reading this has had the flu at least once in their lifetime. The flu is a contagious respiratory illness caused by influenza viruses that infect 5-20% (that is as many as 1 out of 5 people) of people in the U.S. each year. Is it serious? More than 200,000 people are hospitalized and about 36,000 people die yearly from the flu. |
The best way to prevent the flu is by getting a flu vaccination each year. Unfortunately, many of us don't know where to get vaccinated, forget about it, or are simply more afraid of shots than the flu. (A big mistake!) Undoubtedly, a lot more people would be vaccinated if, like tetanus vaccinations, we only had to get a shot every ten years or so. So why can't we?
Normally when we are vaccinated, we are injected with small parts of molecules called 'epitopes'. Our immune system responds by making 'memory cells' that specifically recognize those epitopes. At a second encounter with that epitope, these memory cells help the body mount a much stronger and quicker immune response than the first time. Thus, after a flu vaccination, when the real flu virus tries to attack, our memory cells go to work and usually stop it before we feel sick.
Unfortunately, unlike tetanus which is caused by a single bacterium, flu can be caused by two different families of viruses (called group 1 and group 2). Worse, within these families are many different subtypes each of which has different epitopes. Because of this, every year, scientists have to make some informed guesses as to which type of flu will be common next year and then make the appropriate vaccine.
A discovery by a group of scientists in the United States and another group from Europe and Hong Kong may make the '10 year flu vaccine' a reality. These scientists identified an epitope that appears to be common to the members of the group 1 influenza virus family. Using this epitope, a vaccine was made that was able to prevent death in mice that were challenged with lethal doses of flu viruses. It even protected them against the H5N1 'bird flu' virus.
Hopefully vaccines generated by this epitope will be potent enough, that a single vaccination given every few years will be enough to protect us against all group 1 influenza viruses. Now if scientists can just find a common epitope for group 2!
