The science of heat

by on Sep.30, 2011, under nature, science

YOUR EYES ARE WATERING, your nose is running, and your mouth feels like an inferno. Instinctively, you reach for the glass of cold water in front of you and slosh the liquid down your throat. To your dismay, the water does almost nothing to douse the flames. If only you’d had a glass of full-cream milk – after all, that’s the common cure for chilli heat. Or is it?

Researchers build Life-like cells made of metal

by on Sep.16, 2011, under cool, science, technology

Katherine Sanderson from NewScientist writes:

He has managed to build cell-like bubbles from giant metal-containing molecules and has given them some life-like properties. He now hopes to induce them to evolve into fully inorganic self-replicating entities.

“I am 100 per cent positive that we can get evolution to work outside organic biology,” says Lee Cronin at the University of Glasgow. His building blocks are large “polyoxometalates” made of a range of metal atoms – most recently tungsten – linked to oxygen and phosphorus. By simply mixing them in solution, he can get them to self-assemble into cell-like spheres.

This research certainly pushes our understanding of life into fascinating areas, whilst also raising some interesting debate. I personally am fascinated by the prospect and possible application of this technology in the realm of robotics.

MIT Scientist Captures 90,000 Hours of Video of His Son’s First Words & Graphs It

by on Mar.08, 2011, under Family, Psychology, science, Society

MIT cognitive scientist Deb Roy, started a project five years ago, upon bringing his newborn son home from the hospital, to record his family’s movement and speech inside their house. Since then, Roy has used various techniques to analyze and distill the 200 terabytes of raw data into useful and interesting visualizations.

“For example, Roy was able to track the length of every sentence spoken to the child in which a particular word — like ‘water’ — was included. Right around the time the child started to say the word, what Roy calls the ‘word birth,’ something remarkable happened. ‘Caregiver speech dipped to a minimum and slowly ascended back out in complexity.’ In other words, when mom and dad and nanny first hear a child speaking a word, they unconsciously stress it by repeating it back to him all by itself or in very short sentences. Then as he gets the word, the sentences lengthen again. The infant shapes the caregivers’ behavior, the better to learn.”

Roy also compiled videos showing each time his son used certain words over a period of many months, clearly illustrating how those parts of the child’s linguistic capabilities evolved over time.

Microcosmos: Revealing a secret world

by on Oct.11, 2010, under cool, science

“Microcosmos takes readers into a secret world of extreme close-ups. Some subjects have been magnified by as much as 22million times.”

What may look like a filmmaker

What may look like a filmmaker’s vision of an apocalyptic world is actually a cigarette paper. The blue crystals are additives that keep the lit cigarette burning by producing oxygen
