It's June...so it must be snowing: Great British summer goes from sweltering to shivering in just a week

Five days ago we were flocking to the beach, queueing for ice-creams and slathering on the sunscreen.

Yesterday, we were shivering in summer's first dusting of snow. Yes, snow.

After the hottest spell of the year so far, sleet and snow swept in across northern parts of Britain while the rest of the country also cooled down considerably.

The Cairngorms in Scotland were the chilliest, with temperatures falling to zero while the Pennines and Cumbrian fells managed a mere 3c (37f).

Even by British summer standards, that is a remarkable weather turnaround.

In the Cairngorms, two inches of snow meant visitors were able to build a rather surprised- looking summer snowman.

Five tornadoes slam Colorado; 1 damages mall

Aurora - The National Weather Service says at least five tornadoes hit Colorado, and one damaged a mall in Aurora on Sunday.

There were no immediate reports of serious injuries.

The Weather Service says the tornado that damaged Southlands Mall touched down south of Buckley Air Force Base at 1:49 p.m. and may have been on the ground for about 30 minutes, going on an 8- to 10-mile path across southeast Aurora.

Bats Recognize The Individual Voices Of Other Bats

Bats can use the characteristics of other bats' voices to recognize each other, according to a study by researchers from the University of Tuebingen, Germany and the University of Applied Sciences in Konstanz, Germany. The study explains how bats use echolocation for more than just spatial knowledge.

The researchers first tested the ability of four greater mouse-eared bats to distinguish between the echolocation calls of other bats. After observing that the bats learned to discriminate the voices of other bats, they then programmed a computer model that reproduces the recognition behaviour of the bats. Analysis of the model suggests that the spectral energy distribution in the signals contains individual-specific information that allows one bat to recognize another.

Divining intervention: The growing popularity of dowsing

Two L-shaped metal rods slowly spin in Greg Storozuk's clenched fists as he gently steps through the grass near Sloan's Lake.

"The answer is already known," he says.

The rods rotate into a wide Y. Beneath bushy brows, Storozuk's blue eyes stare vacantly at the horizon. He stops walking.

"Good flowing drinking water. About four gallons a minute. Pretty close to five. Flowing this direction," he says as the rods rotate into a straight line.

It's Not a Triffid, It's A Six Meter High Fungus

© unknownEven these giant (concrete) mushrooms pale in comparison with the 8 meter high fungi from 400 million years ago
We are used to seeing the occasional large mushroom or toadstool in our garden. I've seen pictures of Macrocybe titans ('titan' means big, like the giant Titan Arum flower from Indonesia) on the internet that seem to be about a meter tall, apparently weighing in at 20 kg.

But a six meter high fungus? We need to go back a few millennium. Scientists in the UK discovered fossilized trees from one of the first forests on earth, dating back nearly 400 million years. These trees emerged from a world of early plants barely a few centimeters tall.

But not everything was small. In this ancient forest near Rhynie in Aberdeenshire, there were what the New Scientist writer James O'Donoghue described last year as 'featureless columns standing up to 8 meters high and a meter wide at the bases'.

Wales: Earthquake hits Port Talbot

A minor earthquake has been felt by a number of homes, police said today.

Concerned residents in south Wales contacted the police shortly before 9pm last night after experiencing lights flickering and a tremor.

The British Geological Survey later confirmed there had been an earthquake with a magnitude of three with an epicentre just over six miles north east of Port Talbot.

A spokeswoman for South Wales Police said: "We had three reports yesterday evening. Members of the public from the Wild Mill and Sarn area of Bridgend reported feeling a tremor.

"The British Geological Survey confirmed an earthquake had occurred 10km northeast of Port Talbot with a magnitude of three."

Search for Air France Flight 447 Reveals Astonishing Pollution of World's Oceans

The most alarming piece of news this week emerged when investigators of the doomed Air France flight 447 announced they had found "floating debris" from the plane crash, but it turned out to be only floating trash in the ocean. This is, all by itself, a disturbing commentary on the pollution of the world's oceans: When investigators can't find a plane crash in the ocean because there's already too much trash floating on the surface, we have a problem with pollution.

It's as if they went out to find a plane crash, but ended up discovering that our oceans look like a train wreck. Had they peeked under the surface of the water, they might have found untreated dry cleaning chemicals from a cruise ship, raw feces from a military vessel and tiny bits of plastic that pose an extreme risk to marine life.

With this, air travel investigators learned an important lesson: Just because debris is floating in the ocean doesn't mean a plane crashed there. It could just mean humans are destroying the planet. While 228 passengers sadly died in a tragic air travel accident, we might all die if we don't stop polluting our fragile ecosystems with endless trash.
