SUNDAY 1. JULY, 2012

The "dog days of summer" officially start tomorrow – a sultry period of heat when your shirt sticks to your back. It lasts until 11 August, although some authorities quote a different period, 23 July to 23 August. There are reasons for this that has nothing to do with the weather. The expression comes from ancient Greek, adopted by the Romans. The belief was that the rising of the "dog star" Sirius in conjunction with the sun caused the extra Mediterranean heat that made life so uncomfortable. Sirius, part of the constellation Canis Major (greater dog), is the brightest star in the heavens.
Sirius appeared to the ancients to emit enough energy to be capable of enhancing the heat of the sun, hence the "dog days."The discrepancy in the dates for this phenomenon can be partly attributed to the fact the constellations have moved and Sirius is no longer visible at the same times. The expression remains though, and as late as the 19th century in England it was the time when "wine turned sour, dogs grew mad and all other creatures became languid." The Romans used to sacrifice a brown dog to appease the Gods, but the Britons did not adopt this practice.
Perhaps the description has lasted so long, despite its spurious origins, because July is the warmest and driest month in Britain. The average night and day temperatures are higher than June or August. After the recent rains a few dog days might be welcome.

Popularly dubbed "the book of life," the human genome is extraordinarily difficult to read. But without full knowledge of its grammar and syntax, the genome's 2.9 billion base-pairs of adenine and thymine, cytosine and guanine provide limited insights into humanity's underlying genetics.

Japan opened several solar energy parks on Sunday as a new law came into force requiring companies to purchase renewable energy at a fixed price in a push for alternatives to nuclear power.

With the advent of semiconductor transistorsinvented in 1947 as a replacement for bulky and inefficient vacuum tubeshas come the consistent demand for faster, more energy-efficient technologies. To fill this need, researchers at the University of Pittsburgh are proposing a new spin on an old method: a switch from the use of silicon electronics back to vacuums as a medium for electron transportexhibiting a significant paradigm shift in electronics. Their findings were published online in Nature Nanotechnology July 1.

For eastern Pacific populations of leatherback turtles, the 21st century could be the last. New research suggests that climate change could exacerbate existing threats and nearly wipe out the population. Deaths of turtle eggs and hatchlings in nests buried at hotter, drier beaches are the leading projected cause of the potential climate-related decline, according to a new study in the journal Nature Climate Change by a research team from Drexel University, Princeton University, other institutions and government agencies.

Researchers are hopeful that new advances in tissue engineering and regenerative medicine could one day make a replacement liver from a patient's own cells, or animal muscle tissue that could be cut into steaks without ever being inside a cow. Bioengineers can already make 2D structures out of many kinds of tissue, but one of the major roadblocks to making the jump to 3D is keeping the cells within large structures from suffocating; organs have complicated 3D blood vessel networks that are still impossible to recreate in the laboratory.

LONDON (Reuters) - Rising sea levels cannot be stopped over the next several hundred years, even if deep emissions cuts lower global average temperatures, but they can be slowed down, climate scientists said in a study on Sunday. A lot of climate research shows that rising greenhouse gas emissions are responsible for increasing global average surface temperatures by about 0.17 degrees Celsius a decade from 1980-2010 and for a sea level rise of about 2.3mm a year from 2005-2010 as ice caps and glaciers melt. ...

When watching the Summer Olympics, take a good look at the hands of the competitive swimmers. Chances are, their fingers will be slightly spread. Now new research finds that this hand position creates an "invisible web" of water that gives swimmers more speed.

GENEVA (Reuters) - It has been fancifully dubbed the angel of creation and, to the particular scorn of physicists, the god particle. The Higgs Boson is said to have appeared out of the chaos of the Big Bang 13.7 billion years ago and turned the flying debris from that primeval explosion into galaxies, stars, and planets. Its formal discovery, according to a broad scientific consensus, would be the greatest advance in knowledge of the universe in decades. ...
