Scientists at the Indian Institute of Science in Bangalore, along with researchers in Italy, have found two types of liquid water that have long been suspected to exist below water’s normal freezing point.
Unlike most liquids, water becomes less rather than more dense when it freezes — and it is densest not when it is coldest (at 0 degrees Celsius, just before it freezes) but at 4 degrees C.
These are just two of water’s host of anomalous properties, some of which are crucial to its behaviour in the natural environment.
In 1992, Gene Stanley of Boston University, Massachusetts, and his co-workers carried out computer simulations of water, which suggested that hydrogen bonds in water might produce two different types of liquid if water was made very cold and squeezed to high pressures.

When it comes to choosing a mate, opposites really do attract, according to a Brazilian study that found people are subconsciously more likely to choose a partner whose genetic make-up is different to their own.
They found evidence that married couples are more likely to have genetic differences in a DNA region governing the immune system than were randomly matched pairs.

A pea-sized seahorse, caffeine-free coffee and bacteria that live in hairspray were among the top 10 species discovered last year, a committee of scientists said.
The International Institute for Species Exploration at Arizona State University and an international committee of taxonomists – scientists responsible for species exploration and classification -announced the top 10 new species.
The other species on the list include the very tiny (a snake just a slither longer than 4 inches or 104 millimeters), the very long (an insect from Malaysia with an overall length of 22.3 inches or 56.7 centimeters) the very old (a fossilized specimen of the oldest known live-bearing vertebrate) and the very twisted (a snail whose shell twists around four axes).
Rounding out this year’s list are a palm that flowers itself to death, a ghost slug from Wales and a deep blue damselfish. Continue reading ‘Scientists unveil top 10 newly discovered species’
