Saturdays are colder and wetter than any other day, a major study of weather patterns has revealed.
And the researchers insist people themselves are to blame for the trend - because they drive more during the week and increase dust pollution.
Meteorologists looked at 6.3million pieces of climate data from across Europe between 1991 and 2005.
It's thought to be the most comprehensive weather study ever.
They found Wednesdays have the highest average temperatures and Mondays are the driest. Saturdays were worst on both counts.
The Chinese scientists already successfully implanted similar electrodes in fish, rats, mice and monkeys in research that was driven by military and intelligence interests. This is the first time a bird is being controlled in this way. The scientists reported that they successfully ordered the birds to fly right or left or up or down using a computer and remote control.

The US navy also hopes to use similar implants to exploit sharks' ability to sense minute electrical changes left by a vessel as it sail in the vicinity of the shark. IN this way the navy will have a highly sensitive biological sensor which will be very hard for the enemy to detect.
While looking at the galaxy cluster Abell 2667 with the Hubble Space Telescope, scientists found a spiral galaxy which they nicknamed the "Comet Galaxy."
The gas and stars of the Comet Galaxy-moving through the cluster at speeds of more than 2 million mph-are being stripped away by the tidal forces of the cluster. Also, the pressure of the cluster's scorching gas plasma - known as ram pressure stripping - is adding to the damage.
The dynamics that govern a hurricane's path and intensity are incredibly complex, and one of the least understood is eyewall replacement. In this process the wind speed drops initially when the first cloud walls collapse. But the new walls that move in to replace them re-intensify the wind as they shrink inward - a similar result of angular momentum conservation that makes ice skaters spin faster as they fold their arms.
Now a miniature measuring less than 2in (5cm) in diameter has been identified as a portrait of England's briefest monarch. It had languished in an American collection, its subject described as "unknown woman".
After 12 months of research, David Starkey, the Tudor specialist, believes that it is a contemporary portrait of Lady Jane Grey, the great-granddaughter of Henry VII who was deposed and beheaded by Mary I. "Jane need not remain one of history's invisible women," Dr Starkey said.
"That's really our target," Steve Claggett, the state archaeologist, said Friday while discussing 10 years of research that has been conducted since the shipwreck was found just off Atlantic Beach.
The eclipse began at 2018 GMT, with the Moon totally immersed in the shadow of the Earth between 2244 and 2358 GMT.
During "totality" the moon appeared reddish in colour, as only light that had been filtered through the Earth's atmosphere reached the Moon's surface.
The eclipse was visible from the whole of Europe, Africa, South America, and eastern parts of the US and Canada.
The coppery red Moon was visible across large areas of the UK thanks to clear skies.
"It's not whether you eat insects, fruit, nectar or candy bars or where you eat them - it matters how reliable that food source is from day-to-day," said study leader W. Alice Boyle of the University of Arizona.
To figure out the underlying pressures that drive some birds to leave home for the season, Boyle examined 379 related species of New World flycatchers and compared their size, food type, habitat, migratory behavior and whether or not they fed in flocks.
(New World flycatchers are one of the largest groups of birds in the Americas and include kingbirds, flycatchers, phoebes, manakins and cotingas.)
One of the problems that cosmological models must explain revolves around the amount of disorder in the way that particles in our universe are arranged, which is marked by a quantity called entropy. Cosmologists believe that the universe started out in an ordered, low-entropy state after the big bang, and is gradually becoming more of a mess. But just why it started out so well ordered, when it is much more likely for particles and energy to be created in a greater state of disarray, is something of a puzzle.
