Nanoparticles to Make Hydrogen Cheaper than Gasoline

Nanoparticles to Make Hydrogen Cheaper than Gasoline

According to EE Times, a California-based company called QuantumSphere has developed nanoparticles that could make hydrogen cheaper than gasoline. The company says its reactive catalytic nanoparticle coatings can boost the efficiency of electrolysis (the technique that generates hydrogen from water) to 85% today, exceeding the Department of Energy’s goal for 2010 by 10%.

Who Have Better Memories: Men or Women?

Who Have Better Memories: Men or Women?

Information about even the tiniest details of our daily lives zooms along neurons in our brains and is processed and saved in some predetermined location. How and what information is stored in the memory is in part dependent on whether an individual is a man or a woman. While the underlying mechanisms that explain memory differences between men and women are largely unknown, the fact that there are differences remains an intriguing and insightful area of scientific study. New evidence, reported last week in the journal Current Directions in Psychological Science, indicates that there exist significant differences between men and women pertaining to a unique type of long-term memory known as episodic memory.

Although there are exceptions, in general, relative to men, women appear to have better long-term episodic memory—memories of events or experiences, such as weddings or accidents, that tend to be verbal in nature, meaning the memories are associated with words, whether heard, spoken, or written.

The researcher said that the fish used its mathematical ability to count the number of other fish around it.

At 8 or 9 years old, the typical American schoolgirl is perfecting her cursive handwriting style. She’s picking out nouns, verbs, adjectives and adverbs in sentences, memorizing multiplication tables and learning to read a thermometer. She’s a little girl with a lot to learn. And yet, in increasing numbers, when girls this age run across the playground in T-shirts, there is undeniable evidence that their bodies are blossoming. The first visible sign of puberty, breast budding, is arriving ever earlier in American girls.
