Precise Digits: Does That Make Numbers More Reliable?

Science2.0 - 3 hours 31 min ago

There is such a thing as 'too precise' when it comes to numbers. So what's appropriate? Erik Olsson, CC BY-NC-SA

This Battery Has One Billion Components - But Is The Size Of A Postage Stamp

Science2.0 - 5 hours 33 min ago

How is this for the ultimate miniaturization of energy storage: A new tiny nanopore includes all the components of a battery though it is just is a tiny hole in a ceramic sheet that holds an electrolyte to carry the electrical charge between nanotube electrodes at either end - and 1,000,000,000 can fit in the size of a postage stamp. 

The existing device is a test but the nano-sized battery performs well - and it can be fully charged in 12 minutes, thousands of times.

So How Do Drugs Work?

Science2.0 - 8 hours 48 min ago
All right to start this post I have to warn everyone that there is going to be a little math at the start, but not much, only one easy equation that you need to have a sense of if you are going to understand what drugs that inhibit enzymes do.  This equation is universal and can be easily expanded to describe most molecular interactions.  Actually the most basic form of it is the IC50 equation which has been used as a crutch for describing drug interactions for years.  So if nothing else you might get a sense of what researchers are referring to when they get excited about IC50 values.  -->

Golden Ratio Of Space-Time?

Science2.0 - 10 hours 2 min ago
The golden ratio is known as the divine proportion because it is found so often in nature. It has fascinated mathematicians since Euclid. A golden ratio is when the ratio of two numbers is the same as the ratio of their sum to the larger of the two quantities.

Represented by the Greek letter phi (φ), its value is 1.61803399.

Christmas Party Good News: Drug Reduces Side-Effects Of ‘Binge Drinking’

Science2.0 - 10 hours 2 min ago
Good news for Christmas party season: A new compound has been shown to reduce the harmful side-effects of ‘binge drinking’. It also has the potential for new ways to treat Alzheimer’s and other neurological diseases that damage the brain but showing that would take $1 billion in clinical trials and 10 years of approval and then some generic company would just poach it a few years later anyway. If they simply go the alternative medicine route, the inventors could save themselves the double-blind clinical trials and get right to selling it.

Do 'Typical' Sexual Fantasies Even Exist?

Science2.0 - 11 hours 44 min ago

Fantasies shouldn't be confused with wishes or behaviors. conrado/Shutterstock

By Christian Joyal, Université du Québec à Trois-Rivières (UQTR)

Can we use unusual sexual fantasies to identify sexual deviancy?

Is there a link between what people fantasize about and how they actually behave?

Science Enters The Brown Versus White Bread Battle

Science2.0 - 12 hours 33 min ago
Dietary masochists say you should endure the most difficult brown bread imaginable because 1,000 years ago people had no choice. It's vaguely healthier, we are all told, though if you read more than a few epidemiology studies and saw the lack of methodology you know it casts on doubt almost every health claim made by matching populations to specific foods, not to mention the bizarre beliefs promoted by prominent nutrition 'experts'.
