  • Although electroporation technology is very effective at delivering DNA-based vaccines, the required equipment is bulky, complex and expensive. Now, however, scientists have shown that a converted barbecue lighter is capable of doing the job.
  • Oncolytic viruses selectively kill cancer cells, but this can be ineffective if it alerts the immune system. Now scientists have tweaked these viruses to avoid detection by the immune system, allowing them to track down cancer even after it’s spread.
  • A novel technique that involves directing low-grade radiofrequency energy through sensory nerves is shaping as a promising treatment for arthritis, after delivering significant and long-lasting decreases in pain in an early study.
  • Neuroscientists discovered that electrically stimulating the cingulum brain region creates a mild euphoria complete with laughter, and used it to calm down a patient undergoing a brain surgery where she needed to stay awake. It could be used as a treatment for anxiety, depression or chronic pain.
  • Currently, the most accurate method of checking for anemia is to draw a blood sample and conduct a count of a patient's red blood cells, which contain iron-rich hemoglobin. Soon, however, a smartphone app may be able to non-invasively do the same job.
  • A key culprit behind the painful sting of a fire ant could prove a key component in new creams to treat psoriasis. New research has found that a key compound in the creature's toxic venom can combat some of the symptoms of psoriasis, by helping to repair the barrier function of the skin.
  • Climbing stairs is a chore that's inspired some creative alternatives. Now a team from Georgia Tech and Emory University has developed energy-recycling stairs that take some of the pressure off the knees and ankles, by storing energy from people descending then giving it back as they climb up.
  • A less awful alternative to getting injections is another step closer to reality. In human clinical trials, painless microneedle patches have been found to be just as effective at delivering flu vaccines, and are easier to administer, transport, store and dispose of than regular needles.
  • The brain circuitry involved in falling in love is still being untangled, but neuroscientists have found the regions in brains of prairie voles responsible for pair bonding​. By stimulating those areas they have been able to encourage the formation of such bonds.
  • Frog mucus might seem like the kind of flu remedy a witch doctor would suggest, but researchers have found that certain peptides excreted by frogs can fight off human flu strains. As such, they could be used as emergency stand-ins during flu outbreaks when regular vaccines aren’t available.
  • Science
    Scientists have unearthed what could be a useful weapon on one of the key frontiers in the fight against superbugs, discovering an extract from the Brazilian peppertree that can neutralize a dangerous antibiotic-resistant staph bacteria.
  • Scientists have been unable to develop a vaccine against the common cold, largely because there are over 100 strains of rhinoviruses, the most common cause of the infection. Now, a team at Emory University has stimulated the immune system by mixing multiple types into one vaccine.
