Word of the day: sub-zeptojoule

Just edges out sub-femtonewton...actually, my kids have been doing this in the bathtub for several years now.

Liquid droplets are injected into the device from an atomiser and observed with an optical microscope. The Texas physicists found they could move, rotate or even merge droplets by applying electric or magnetic fields, and that they were able to control the potential energy of a droplet on the sub-zeptojoule (10-21 J) scale. Moreover, the force could be controlled with sub-femtonewton (10-15 N) resolution, which is about two orders of magnitude better than can be achieved with optical tweezers. The floating particles can also be positioned to within an accuracy of 300 nanometres (figure 2). via physicsweb

Warning! Gravitational Field Present

Colder, slower, better...Yes, but is it water? Anti-water?

I really don't understand this story. I know that two regular Hydrogens and one friendly Oxygen make one delicious molecule of water. But, what if they're ANTI-HYDROGENS?!! Are we sure this is a good idea?

The international ATRAP collaboration has measured the velocity of slow-moving or "cold" antihydrogen atoms for the first time. ATRAP is one of two experiments at CERN's antimatter decelerator that hopes to capture large numbers of cold antihydrogen atoms in a trap. The anti-atoms captured by the ATRAP and ATHENA teams could be used for a variety of experiments in fundamental physics, including the most accurate ever test of CPT symmetry (G Gabrielse et al. 2004 Phys. Rev. Lett. 93 073401).

'Anti-plume' Found Off Pacific Coast

Now we need Bruce Willis and his team to construct a giant drain-plug and descend into the depths of the ocean to save mankind.

A North American team of scientists has documented for the first time a new phenomenon – the creation of a void in the seafloor that draws in – rather than expels – surrounding seawater. 'Anti-plume' Found Off Pacific Coast

Parasites, Typhoid and Worms! Oh My!

If the cowardly lion really wanted to be scared, he should have hoisted a drink of water! This report from the World Health Organization is enough to scare me off the stuff for good!

The Environment: Where's The Risk, And Where Are Children Safe?

* Unclean water causes diarrhea, which kills an estimated 1.8 million people worldwide each year, 1.6 million of whom are children under five. It's also responsible for many diseases including cholera, dysentery, guinea worm, typhoid and intestinal worms.

* 86% of all urban wastewater in Latin America and the Caribbean, and 65% of all wastewater in Asia, is discharged untreated into rivers, lakes and oceans.

* The Ganges River alone has 1.1 million litres of raw sewage dumped into it every minute, a startling figure considering that one gram of faeces in untreated water may contain 10 million viruses, one million bacteria, 1000 parasite cysts and a hundred worm eggs. Diseases which result include diarrhoea, cholera, dysentery, typhoid, guinea worm, intestinal worms and trachoma.

The Nose Knows at Yale

Well, the Yalies have figured out how a fly smells. There's a joke in there somewhere, I'm sure.

Before they go and figure out how to make bad water smell good, I hope they check into one of these...

Yale Scientists Decipher Odor Code
New Haven, Conn. -- Yale scientists, working with the fruit fly as a model, have discovered how odors are encoded by the olfactory system into the complex messages that are sent to the brain. The study, published in the June 25 issue of Cell, provides new insight into how animals sense and distinguish odors, a process that is essential to identifying food, mates and predators.
