Blood-brain barrier (noun, “blood bray-n bare-ee-er”)A layer of cells between the blood vessels and the cells of our brains. The brain is very delicate and can’t be exposed to just anything in the blood. This barrier of cells lets oxygen and nutrients in. But it keeps out foreign substances, such as dangerous bacteria. The barrier is important, but it can also be difficult to deal with. When...

Cosmetics commercials extoll the virtues of long, luxurious eyelashes. They even sell products to make them longer. But, new research indicates, in terms of eye health, long isn’t always better.There’s a so-called “sweet spot” in the range of lash lengths. It is about one-third the width of the eye. And it’s here that lash length appears most helpful. Eyelashes much longer than that will funnel...

For the first time, scientists have shown a direct link between rising levels of carbon dioxide — or CO2 — in Earth’s atmosphere and an increase in how much solar energy warms the ground. The finding supports a key theory about what’s behind the recent worldwide warming of Earth’s climate. It links a measurable share of that warming to human activities that release CO2. These include the burning...

Zorana Berberovic gently lifts a small black mouse by its tail. As its hind legs rise up off the floor of its cage, the research technician slips a tiny vial under the mouse’s bottom. Berberovic lightly strokes her gloved finger against its belly. Within seconds, she is rewarded. A dribble of pee enters the vial."They have small bladders so there's not much," Berberovic says. Luckily, she adds, "...

Popcorn is one of my favorite foods. I love its squeaky crunch and the taste of butter and salt. Popping my own corn on the stove top makes me think of relaxing with a book or settling in with a fun movie. And now, it also makes me think of science.Scientists recently popped corn in a conventional oven to determine at what temperature the kernels explode. Then they invited the rest of us to run...

Ocean animals have been getter bigger over the last half-billion years. Not a little bigger. Not even a lot bigger. They have mushroomed gigantically, scientists now conclude.Their new finding lends support for something known as “Cope’s rule.” It holds that animals tend to evolve into species that are much larger than their distant ancestors. This hypothesis takes its name from the 19thcentury...

HOUSTON, Texas — Infants eating small but regular doses of peanut butter are less likely to develop an allergy to peanuts than are babies eating no peanuts. That’s the surprising finding of a new study.Many people, starting in childhood, develop a serious allergy to peanuts. Eventually, even the briefest exposure — such as a kiss from someone who recently ate peanuts — may cause a serious...

Denise Gardner was a finalist in the 2003 Intel ISEF. At the fair, she presented her research on red wine color stability. Fermented grapes have taken Gardner’s career a long way, from Napa Valley to Penn State.Check out the SSP blog post on why Gardner credits Intel ISEF for much of her professional growth, and will be giving back at the upcoming Intel ISEF in Pittsburgh this May.
