Hundreds of bacteria isolated from soil samples are able to live exclusively on antibiotics as a food source, according to a report published today (April 3) in Science.
Bees learn to recognise particular bushes, trees and flowers, according to scientists who say these insects are surprisingly sophisticated at navigating their natural environment.
The research, published in the latest issue of the Journal of Experimental Biology, shows that bee behaviour is not hard-wired as once believed.
Lead author Dr Adrian Dyer, an Australian vision researcher from Monash University in Melbourne, says bees can learn new tasks, despite their tiny brain size.
"This gives us a real insight into how neurones work and how neurones can interact and learn how to solve tasks," he said.

Blame all the lightning strikes happening this summer on the Western Ghats and the Arabian Sea, say a team of scientists at the Centre for Earth Science Studies (CESS).
The two geographical structures that sandwich the state provide the temperature contrast that ultimately leads to the highest incidence of lightning in the country.
Though mountains are a major factor known for the formation of the cumulonimbus clouds (Cb) that cause lightning, R Vishnu, S Murali Das and G Mohan Kumar of the Atmospheric Sciences Division of the CESS have experimentally proved it.

An earthquake with a preliminary magnitude of 5.0 shook Tokyo buildings on Friday, but there were no immediate reports of injuries or damage.
The earthquake registered four out of seven on a Japanese scale of quake intensity, a government agency said, a level that suggests hanging objects would swing considerably but there was unlikely to be serious damage.

A 6.4 magnitude earthquake struck southern Iran on Friday, an official Iranian news agency reported but there were no immediate reports of damage or casualties.
If you live in Missouri and have a hummingbird feeder, now is the time to put it out. Observers in Arkansas and Kansas report seeing ruby-throated hummingbirds already.
Lanny Chambers, of Fenton, Mo., maintains a website that encourages birdwatchers from the Rocky Mountains to the Atlantic Ocean and from the Gulf of Mexico to Canada to report their first hummingbird sightings each year.
Sighting reports are posted daily at www.hummingbirds.net, so anyone who visits the site can follow the progress of the annual rubythroat migration.

A warmer world could be a more explosive one. Global warming is having a much more profound effect than just melting ice caps - it is melting magma too.
Vatnajökull is the largest ice cap in Iceland, and is disappearing at a rate of 5 cubic kilometres per year.
Carolina Pagli of the University of Leeds, UK, and Freysteinn Sigmundsson of the University of Iceland have calculated the effects of the melting on the crust and magma underneath.
They say that, as the ice disappears, it relieves the pressure exerted on the rocks deep under the ice sheet, increasing the rate at which it melts into magma. An average of 1.4 cubic kilometres has been produced every century since 1890, a 10% increase on the background rate.
Frequent eruptions
In Iceland there are several active volcanoes under the ice. The last big eruption was in 1996 at Gjàlp, and before then in 1938 - a gap of 58 years. But Pagli and Sigmundsson say that the extra magma produced as the ice cap melts could supply enough magma for similar eruptions to take place every 30 years on average.

Employees at an oil company have discovered the carcasses of 32 seals along the northern Caspian Sea coast near the Kalamkas oil field in Kazakhstan, the republic's emergencies ministry said on Friday.
The region has already been plagued by a similar tragedy in March 31 - May 14 2007, when a total of 928 seals, including 710 baby seals, died near the Kalamkas oil field.
A research group from Kazakstan's Biological Security Research Institute and Institute of Microbiology and Virology cited the phocine distemper virus (PDV), which has been blamed for the deaths of fin-footed mammals all over the world since 1988, as responsible for the deaths.

When police knocked on Donna Lemire's door late Tuesday night and told her to leave, it was not an April Fool's joke.
A passing storm brought torrential downpours and lightning, which struck outside her building in the Shadowbrook Condominium complex around 11:30 p.m., causing a water pipe to burst and flames to erupt from the third floor ceiling.
Fire Lt. Mark Nelson said a lightning bolt struck a tree outside 17 Shadowbrook Lane, traveled into the ground and through Lemire's building.

Hail stones the size of cricket balls flattened about 100 huts, injured three persons and killed cattle in the Bindol gram panchayat area last night.
The storm had started around 9.30pm and grew with each passing minute till it stopped two hours later. A fresh shower of hailstones hit the area again early this morning.
"First came the wind. Strong gusts blew away roofs of tiles and tin. Then came the hailstones. As the night progressed, the size of the stones increased and they came hurtling down, some of them as big as cricket balls," said Narayan Bhowmik, a tea stall owner in Bamua, 20km from here and one of the worst hit areas. The storm left scars across a 9km radius.
