  • A laser beam can alter a fly’s behavior and make it mate with just about anything — even a ball of wax, according to scientists at the Howard Hughes Medical Institute. The researchers have developed an experiment which involves shining an infrared laser directly at the head of a fly whose brain has been altered using heat-activated proteins. This alteration allows the laser, dubbed the "Fly Mind-Altering Device" (FlyMAD), to activate specific neurons involved in mating.
  • behavioral modification was so strong that it persisted for about 15 minutes after the laser was turned off.

  • The Food and Drug Administration has already approved his technique for human trials, and he has secured funding from the Army to conduct the feasibility phase. Dr. Rhee is currently lobbying for funds to conduct a full trial. If he’s successful human trials could begin as early as next year.
  • What Dr. Rhee hopes to test on humans is a method he worked out for the past couple decades on pigs. Patients would be injected with a cold fluid to induce severe hypothermia. Clinically hypothermia is characterized by the drop of a person’s body temperature from its normal 98.6 degrees Fahrenheit (37 degrees Celcius) to lower than 95 degrees (35 C). Below 95, the heart, nervous system and other organs begin to fail. The strict range is indicative of a metabolic system with strict temperature requirements for proper function (death waits only a few degrees the other way as well). Dr. Rhee’s method involves injecting patients with a cold fluid that would bring the body’s temperature down to 50 degrees Fahrenheit (10 C). Sounds chilling, but when he induced the extreme hypothermia in pigs they came out just fine. Heart function, breathing, and brain function was completely normal.
  • Dr. Rhee is no stranger to high-stakes medicine. The native South Korean was trained at the Uniformed Services University Medical School in Bethesda, Maryland. Following a fellowship in trauma and critical care at the University of Washington’s Harborview Medical Center he served in the US Navy as director of the University of South California’s Navy Trauma Training Center at Los Angeles County. He was then sent to Afghanistan where he was one of the first surgeons at Camp Rhino. Later he started the first surgical unit at Ramadi, Iraq. His cool under fire was on display nationally as he performed surgery on US Representative Gabrielle Giffords after she was shot through the skull in the Tucson shootings this past January. His experience with induced hypothermia came into play the night of the shootings when Dr. Rhee removed part of the congresswoman’s skull. The wound had raised her body temperature and began “cooking the brain.” He used a device to cool Rep. Giffords’ skin.

    BGU software engineering students have developed innovative technology that could enable people to operate a computer without using a keyboard or mouse - only their brainwaves. While there have been previous attempts to develop devices to read brainwaves and operate specific programs, they were cumbersome and not feasible outside of a laboratory setting. The BGU technology features a helmet equipped with 14 EEG connect points that sense brain activity. According to Dr. Rami Puzis, "The technology is designed to assist those who are physically disabled who might otherwise be unable to manipulate a computer mouse or keyboard." The student team, Ori Ossmy, Ofir Tam and Ariel Rozen, developed the prototype application for their bachelor's degree project under supervision at BGU by Prof. Mark Last, Dr. Rami Puzis, Prof. Yuval Elovich and Dr. Lior Rokah. As part of a recent demonstration, a student composed and sent a hands-free e-mail using only thought combined with the adaptive hardware. The students and BGU team plan to continue research working with the disabled.

Colliding Atmospheres: Mars vs Comet Siding Spring - NASA Science - 0 views

  • "We hope to witness two atmospheres colliding," explains David Brain of the University of Colorado's Laboratory for Atmospheric and Space Physics (LASP).  "This is a once in a lifetime event!"
  • Everyone knows that planets have atmospheres.  Lesser known is that comets do, too.  The atmosphere of a comet, called its "coma," is made of gas and dust that spew out of the sun-warmed nucleus.  The atmosphere of a typical comet is wider than Jupiter.
  • The timing could scarcely be better.  Just last year, NASA launched a spacecraft named MAVEN to study the upper atmosphere of Mars, and it will be arriving in Sept. 2014 barely a month before the comet. MAVEN is on a mission to solve a longstanding mystery: What happened to the atmosphere of Mars?  Billions of years ago, Mars had a substantial atmosphere that blanketed the planet, keeping Mars warm and sustaining liquid water on its surface. Today, only a wispy shroud of CO2 remains, and the planet below is colder and dryer than any desert on Earth. Theories for this planetary catastrophe center on erosion of the atmosphere by solar wind.
