Yellowstone’s amphibians declining fast due to climate change

Washington, Oct 29 (ANI): A research has determined that despite being protected longer than anywhere else on Earth, Yellowstone National Park’s amphibians are declining fast, all due to climate change.

Yellowstone National Park, founded in 1872, has been protected by law longer than anywhere else in the world.

In 1992 and 1993, researchers in Elizabeth Hadly’s group at Stanford University surveyed amphibians dwelling in ponds left behind by glaciers in northern Yellowstone National Park.

Over the last three summers, Hadly’s graduate student Sarah McMenamin repeated the study.

Why Neanderthals had big noses

London, Oct 29 : Anthropologists have suggested that Neanderthals had big noses because of the degree to which their face used to jut forward, indicating that the odd feature was a fluke of evolution, not some grand adaptation.

The Neanderthal nose has been a matter of befuddlement for anthropologists, who point out that modern cold-adapted humans have narrow noses to moisten and warm air as it enters the lung, and reduce water and heat loss during exhalation.

Big noses tend to be found in people whose ancestors evolved in tropical climates, where a large nasal opening helps cool the body.

But Neanderthals go against this trend, according to Tim Weaver, a palaeoanthropologist at the University of California, Davis.

Now, laptops to detect quakes!

Washington, Oct 29 : In a new project, scientists have used laptops to detect several earthquakes, taking the help of small accelerometer chips inside the machines.

The project is known as the project Quake Catcher Network (QCN).

Scientists have found out that the tiny accelerometer chip is a pretty good earthquake sensor as well, especially if the signals from lots of them are compared, in order to filter out more mundane sources of laptop vibrations, such as typing.

The project has about 1500 laptops connected in a network that has detected several tremors, including a magnitude 5.4 quake in Los Angeles in July this year.

Now, roses, violets and lilies under threat by global warming

Washington, Oct 29 : A new study has determined that some of the world’s most beloved species of flowers like lilies, orchids, violets, roses, and dogwoods have also been hit by global warming.

The study, by scientists at Harvard University, US, have found that different plant families near Walden Pond in Concord, Massachusetts, have borne the effects of climate change in strikingly different ways.

Over the past 150 years, some of the plants in Thoreau’s woods have shifted their flowering time by as much as three weeks as spring temperatures have risen, the researchers say, while others have been less flexible.

British Airways is now effectively ‘London Airways’

London, Oct 29 : British Airways has stopped being the UK’s national carrier and effectively become London Airways.

Though the airline still operates flights from Manchester, Newcastle, Edinburgh, Glasgow and Aberdeen, but passengers choice of destination from these cities is limited: They can fly to any other city they like – so long as it is London, The Independent reported.

At the weekend, the airline axed the last international flight that neither departed from nor arrived at one of the London airports, the 44-year-old link from New York to Manchester.

The slots at JFK have been redeployed for a new BA route from Gatwick.

We first look around the nose to recognise a familiar face

Washington, October 29 : An American study has revealed that the first two points that people look at to tell whether a face is familiar to them or not are around the nose.

Cognitive Scientists Janet Hui-wen Hsiao and Garrison Cottrell from the Temporal Dynamics of Learning Center at the University of California, San Diego, examined this by showing volunteers frontal-view images of faces, one at a time, and recording their eye movements.

They used an eye tracker to record the movements of the participants, which helped detect where on the faces shown the volunteers looked.
