The device combines flexible electronics and human stem cells – the body’s ‘reprogrammable’ master cells – to better integrate with the nerve and drive limb function. Credit: University of Cambridge Researchers have developed a new type of neural implant that could restore limb function to amputees and others who have lost the use of their arms or legs. In a study carried out in rats, researchers from the  University of Cambridge  used the device to improve the connection between the brain and paralyzed limbs. The device combines flexible electronics and human stem cells – the body’s ‘reprogrammable’ master cells – to better integrate with the nerve and drive limb function. Previous attempts at using neural implants to restore limb function have mostly failed, as scar tissue tends to f...

  A dusty lunar landscape, as envisioned by NASA’s Advanced Concepts Laboratory. Credit: NASA On a cold winter day, the warmth of the sun is welcome. Yet as humanity emits more and more greenhouse gases, the Earth’satmosphere traps more and more of the sun’s energy and steadily increases the Earth’s temperature. One strategy for reversing this trend is to intercept a fraction of sunlight before it reaches our planet. For decades, scientists have considered using screens, objects, or dust particles to block just enough of the sun’s radiation—between 1 or 2%—to mitigate the effects of global warming. A University of Utah-led study explored the potential of using dust to shield sunlight. They analyzed different properties of dust particles, quantities of dust, and the orbits that would be best suited for shading Earth. The authors found that launching dust from Earth to a way station at the “Lagrange Point” between Earth and the sun (L1) would be most effective but would require astro...

  GSOWIFBBSOWOFI3723958 New research published in the European Heart Journal has debunked the “obesity paradox,” which suggested that overweight or obese heart failure patients had a lower risk of hospitalization or death compared to those with normal weight. The study found that using waist-to-height ratio measurements instead of body mass index (BMI) eliminates the perceived survival advantage for individuals with a BMI of 25kg/m 2  or more. Study shows ‘obesity paradox’ does not exist: waist-to-height ratio is a better indicator of outcomes in patients with heart failure than BMI. New research has debunked the idea that there is an “obesity paradox,” whereby patients with heart failure who are overweight or obese are thought to be less likely to end up in the hospital or die than people of normal weight. The study, which was published in the  European Heart Journal [1]  on March 22, shows that if doctors measure the ratio of waist to height of their patients, rath...
