Over 70 percent of high school teachers are female and girls in high school take as many math courses as boys, yet it's believed female interest in math and science still wanes considerably in high…

There are two mistakes you can make when you read a scientific paper: You can believe it (a) too much or (b) too little. The possibility of believing something too little does not occur to most…

At today’s IEEE International Solid State Circuit Conference, IMEC introduced its prototype of a 60GHz multiple antenna receiver, and invites industry to join its 60GHz research program. The 60GHz…

Thousands of times a year, a single cell extraction from an embryo is performed to screen for genetic diseases. As of January 2008, the cell could be allowed to divide and the copy used for research…

A new study documents malformations seen in an infant born to a kidney transplant recipient who had taken mycophenolate mofetil (MMF), a widely used immunosuppressant available commercially as…

A study by UC Irvine ecologists finds that excess nitrogen in tropical forests boosts plant growth by an average of 20 percent, countering the belief that such forests would not respond to nitrogen…

Scientists from the University of Bonn are researching which plants giant dinosaurs could have lived off more than 100 million years ago in order to find out how they were able to become as large as…

Quantitative modeling of a biological pathway normally involves intense computer simulations to crunch all available data on the dozens of relevant reactions in the pathway, producing a detailed…

When something is moving close to the speed of light, the fastest anything can move, sending ahead information in time to make mid-path flight corrections sounds impossible. Not quite, say…

Citizen Science – Past, Present & Future, to be held at Vaughan College, the University’s Institute of Lifelong Learning, will showcase longstanding research from the University’s Departments of…

At yesterday’s International Solid State Circuit Conference, Holst Centre - founded by the Belgian nanoelectronics research center IMEC and the Dutch research center TNO - presented a plastic 64-bit…

Computers are increasingly being used by those seeking sexual thrills and this use is helping inspire new and innovative technologies, according to a cybersex expert from University of Portsmouth.…

Antioxidants are believed to help ward off illness and boost the body’s immune system by acting as free radical scavengers, helping to mop up cell damage caused by free radicals. But you don't have…

Scientists at Carnegie Mellon University’s Molecular Biosensor and Imaging Center have developed new “fluorogen activating proteins” (FAPs) that will become a key component of novel molecular…

I'm trying to find time to write a paper, and thus I've neglected my blog. But here are two interesting links: Super Tuesday and Science Debate 2008: The US National Academies of Sciences have…
