• 06:00 Computerized Face Recognition Software Can Rapidly See Through Disguises

  Read the story at ScienceDaily
  A rapid but superior method for computerized face recognition could revolutionize security systems especially if it can see through disguises. New software solves the variation problems caused by different light levels and shadows, viewing direction, pose, and facial expressions. It can even see through certain types of disguises such as facial hair and glasses.

• 06:00 Army Study Improves Ability To Predict Drinking Water Needs

  Read the story at ScienceDaily
  When soldiers leave base for a three-day mission, how much water should they bring? New research may now provide military planners an accurate answer. The study improves an existing water needs equation by 58-65 percent. If the new formula works in the field, as expected, it could accurately predict water needs not only for soldiers, but also for civilians who work or exercise outdoors.

• 06:00 Faster, More Cost-effective DNA Test For Crime Scenes, Disease Diagnosis

  Read the story at ScienceDaily
  Scientists in Japan are reporting development of a faster, less expensive version of the fabled polymerase chain reaction, a DNA test widely used in criminal investigations, disease diagnosis, biological research and other applications. The new method could lead to expanded use of PCR in medicine, the criminal justice system and elsewhere, the researchers say.

• 06:00 Hydrogen Technology Steams Ahead

  Read the story at ScienceDaily
  Could the cars and laptops of the future be fueled by old chip fat? A group of engineers believe so, and are developing an energy efficient, environmentally-friendly hydrogen production system. The system enables hydrogen to be extracted from waste materials, such as vegetable oil and the glycerol by-product of bio-diesel. The aim is to create the high purity hydrogen-based fuel necessary not only for large-scale power production, but also for smaller portable fuel cells.

• 06:00 One-finger Exercise Reveals Unexpected Limits To Dexterity

  Read the story at ScienceDaily
  "Push your finger as hard as you can against the surface. Now as hard as you can but move it slowly -- follow the ticking clock. Now faster. Now faster." These were the commands for volunteers in a simple experiment that casts doubt on old ideas about mechanisms to control hand muscles. Complete understanding of the result may help explain why manual dexterity is so vulnerable to aging and disease, and even help design more versatile robotic graspers.

• 06:00 Power Of US Cities To Mitigate Climate Change And Steps They Need To Take To Adapt

  Read the story at ScienceDaily
  US cities are starting to plan ways of coping with climate change, says a new report. Flooding of subways and other infrastructure caused by extreme weather and sea level rise, shortages of food, water and energy, and health and economic risks are among concerns of city planners in 18 US cities surveyed, including New York, Chicago, Atlanta, Denver, West Palm Beach, Portland and Las Vegas. Many are also implementing carbon reduction programs for municipal activities as a prelude to leading citizen CO2 reduction efforts.

• 20:15 Current Search For Heart Disease Treatment May Not Be Fruitful

  Read the story at ScienceDaily
  A protein used by doctors to indicate a patient's risk of coronary heart disease may have drug developers barking up the wrong treatment tree, according a new study. Their research suggests that C-reactive protein, an enticing target for scientists working on new treatments for coronary heart disease, may not have a role in causing the disease, even though it is a predictive marker.
