  1. Controlled burns help prevent wildfires; Climate change is limiting their use
    Climate change means the American West will have 17% fewer safe days to light prescribed fires for wildfire management, according to new research. Winter, however, will see a net 4% increase in the number of favorable days. Implementing controlled burns in the West will require changes to policy and the availability of firefighters.
  2. Lasers deflected using air
    Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original quality of the beam.
  3. Type 2 diabetes diagnosis at age 30 can reduce life expectancy by up to 14 years
    An individual diagnosed with type 2 diabetes at age 30 years could see their life expectancy fall by as much as 14 years, an international team of researchers has warned. Even people who do not develop the condition until later in life – with a diagnosis at age 50 years – could see their life expectancy fall by up to six years, an analysis of data from 19 high-income countries found.
  4. Bioengineering breakthrough increases DNA detection sensitivity by 100 times
    Researchers have pushed forward the boundaries of biomedical engineering one hundredfold with a new method for DNA detection with unprecedented sensitivity.
  5. Study quantifies satellite brightness, challenges ground-based astronomy
    The ability to have access to the Internet or use a mobile phone anywhere in the world is taken more and more for granted, but the brightness of Internet and telecommunications satellites that enable global communications networks could pose problems for ground-based astronomy. Scientists confirm that recently deployed satellites are as bright as stars seen by the unaided eye.
