TechGround-thumping cheers help scientists
Eager to test new sensors before the next ‘big one,’ earthquake scientists make use of a predictable source of ground-shaking: football fans.
-
TechPhoning in earthquakes
Sensors in your internet-connected phone, tablet or personal computer could help detect earthquakes more quickly and reliably.
-
ChemistryBacteria become source of ‘greener’ blue jeans
Manufacturing indigo to dye blue jeans now relies on harmful chemicals. But researchers have found a less polluting way to produce the blue tint: bacteria.

Health & MedicineDo mosquitoes love you? Blame your parents
By studying twins, scientists found that how attractive we are to mosquitoes depends partly on our genes. That could lead to better bug repellents.
-
Health & MedicineSkip the soft drinks, period
Beyond the quest for trim waistlines and cavity-free teeth, girls have another reason to shun sodas and other sweetened drinks. These beverages may help launch the body’s menstrual cycles at an earlier age.
-
AnimalsResilient hearts for deep-sea divers
How do aquatic mammals have enough energy to hunt prey while steeply dropping their heart rate to stay underwater? A new study of dolphins and seals provides clues.
-
ClimateThunderstorms can generate powerful radiation
Thunderstorms don’t just hurl lightning bolts. Some churn out high-energy radiation that can be seen by spacecraft. This radiation offers scientists a glimpse of the inner workings of thunderclouds.

PhysicsPicture This: Christmas from space
Satellite images show that cities brighten during holidays. Charting such changes can point to factors affecting energy use and contributing to global warming.
-
GeneticsWhy animals often ‘stand in’ for people
Rats, birds, fish — even flies and worms — can stand in for people in laboratory testing. This allows scientists to safely evaluate harmful chemicals as well as to identify and test potential new drugs. But such tests will never be a foolproof gauge of effects in people.

Health & MedicineCan soft drinks speed aging?
A new study suggests a reason why daily sugary-soda drinkers are more prone to disease: Guzzling these drinks shortens the protective caps on chromosomes. If the caps get too short, cells die.
