• Bella moths use poison to attract mates: Scientists are closer to finding out how
  Researchers sequence the bella moth genome, which they used to pinpoint specific genes that may confer immunity to noxious alkaloids.
• Eye-opener: Pupils enlarge when people focus on tasks
  Normally, a person's pupils naturally widen (or dilate) in low-light environments to allow more light into the eye. However, in a new study, researchers reported that a person's pupils also dilate when they are concentrating on tasks. In particular, they found that the more a person's eyes dilated during the task, the better they did […]
• Life goals and their changes drive success
  Though life goals change over time, a study of teen goals indicates that goals of education and high prestige can drive success.
• Simulated microgravity affects sleep and physiological rhythms
  Simulated effects of microgravity significantly affect rhythmicity and sleep in humans, a new study finds. Such disturbances could negatively affect the physiology and performance of astronauts in space.
• Genetically engineering a treatment for incurable brain tumors
  Scientists are developing and validating a patent-pending novel immunotherapy to be used against glioblastoma brain tumors. Glioblastomas are almost always lethal with a median survival time of 14 months. Traditional methods used against other cancers, like chemotherapy and immunotherapy, are often ineffective on glioblastoma.
• Social programs save millions of lives, especially in times of crisis
  Primary health care, conditional cash transfers and social pensions have prevented 1.4 million deaths of all ages in Brazil over the past two decades, according to a new study. If expanded, these programs could avert an additional 1.3 million deaths and 6.6 million hospitalizations by 2030.
• New compound from blessed thistle promotes functional nerve regeneration
  Blessed thistle (Cnicus benedictus) is a plant in the family Asteraceae. For centuries, it has been used as a medicinal herb as an extract or tea, e.g. to aid the digestive system. Researchers have now found a completely novel use for Cnicin. Animal models as well as human cells have shown that Cnicin significantly accelerates […]
• Shoe technology reduces risk of diabetic foot ulcers
  Researchers have developed a new shoe insole technology that helps reduce the risk of diabetic foot ulcers, a dangerous open sore that can lead to hospitalization and leg, foot or toe amputations.
• Researchers develop a new way to safely boost immune cells to fight cancer
  Researchers explore a cancer immunotherapy treatment that involves activating the immune cells in the body and reprogramming them to attack and destroy cancer cells. This therapeutic method frequently uses cytokines, small protein molecules that act as intercellular biochemical messengers and are released by the body's immune cells to coordinate their response.
• Glial hyper-drive for triggering epileptic seizures
  When epileptic patients suffer seizures, their brain is undergoing repetitive and excessive neuronal firing. But what triggers this has stumped scientists for years. Now, researchers have used fluorescence calcium sensors to track astrocytes' role in epileptic seizures, finding that that astrocyte activity starts approximately 20 seconds before the onset of epileptic neuronal hyperactivity.
