Mosquito bites are a scourge to campers and spread deadly malaria infections. While nets and insecticides have long been the answer to blocking the winged menaces, researchers have discovered a simple way of grounding mosquitoes: fog.
Plants aren’t typically known for their speed, but the carnivorous Venus flytrap can close its jaw-like leaves in the blink of an eye. Charles Darwin once referred to the Venus flytrap as “one of the most wonderful plants in the world.” But despite the plant’s notoriety, its closing mechanism remains a mystery 250 years after its discovery.

The sickening thud of a bird crashing into a window is an all-too-familiar sound for many Canadian homeowners. Birds often mistake windows for openings, flying into the glass at full speed. A startling new analysis suggests about 22 million Canadian birds die each year from such crashes, researchers reported Sept. 4 in Wildlife Research.
Researchers are in the early stages of creating a new method that uses bubbles within bubbles to deliver chemotherapy drugs, and could someday reduce the treatment’s significant side effects.

On Tuesday we Californians will vote on Prop 37 to decide whether or not to force companies to label their genetically modified foods. The European Union already requires the labeling of these GMOs, and some European countries ban genetically modified products outright. This labeling paints the picture that GMOs are dangerous and shouldn’t be developed let alone eaten.
As candy-crazed kids run up and down driveways this Halloween, guided only by the flickering light of jack-o’-lanterns, it’s easy to appreciate the low light vision that’s preventing trips over superhero capes and princess dresses. But despite the usefulness of night vision, scientists have only now identified the important chemical process that compensates for visual errors in low light.

American researchers have generated a record-setting laser pulse so short that it makes most everything else seem like an eternity. The pulse lasted just 67 attoseconds, which is about two million billion times faster than the blink of an eye. The previous record, set by European researchers in 2008, was about 20 percent slower.

If you’ve ever dealt with an exploded can of frozen soda in the freezer, you’ve seen firsthand that ice takes on a crystal structure. At freezing temperatures, water molecules line up to form geometric shapes, creating ice’s crystal structure. The crystal structure takes up more space than the loose liquid water molecules, causing water to expand when frozen.
Towering 15 stories above the Antarctic landscape, the white balloon casts a long, dark shadow across the snow. The ground crew makes final preparations for launch, filling the balloon with helium and securing its cargo. In one fluid motion, the workers free the balloon from the Earth. Rising into the air, it becomes a fading silhouette in a cloudless sky.
