Inland Ants Often Prefer Salt Over Sugar, Implying Salt May Be A Limitation On Their Activity

Ants prefer salty snacks to sugary ones, at least in inland areas that tend to be salt-poor, according to a new study published this week in the journal Proceedings of the National Academy of Sciences.

Ants far from the coast are more attracted to a dilute salt (NaCl) solution than to a more concentrated sugar solution, probably because plant-eating ants in salt-poor inland areas are salt-starved.

Ecologists from the University of California, Berkeley, the University of Arkansas at Little Rock (UALR) and the University of Oklahoma tested the salt versus sugar preferences of ants from North, Central and South America, using ant populations at varying distances from the ocean. While ocean spray and storms can spread salt tens of miles from the coast, areas farther inland are often deprived of salt, and the researchers suspected they might find different taste choices between coastal and inland ants.

Magnitude-6.1 quake shakes Aleutian Islands, Alaska

Anchorage - The U.S. Geological Survey says a significant earthquake has jolted the ocean floor near Alaska's remote Aleutian Islands.

The agency says in a preliminary report that the magnitude-6.1 quake struck the seismically active but sparsely populated island chain at 4:49 a.m. Sunday.

It was centered at a depth of about 39 miles, and 35 miles southwest of the island of Atka, which lies about 1,100 miles southwest of Anchorage.

Recent Hurricane History Provides Diverging Interpretations On Future Of Hurricane Activity

In a paper published in the journal Science, scientists Gabriel A. Vecchi of NOAA's Geophysical Fluid Dynamics Laboratory, Kyle L. Swanson of the University of Wisconsin - Milwaukee Atmospheric Sciences Group and Brian J. Soden from the University of Miami's Rosenstiel School of Marine and Atmospheric Science teamed up to study hurricane data observed over more than 50 years.

Looking at recent observations leads to two hypothesize that imply vastly different futures; only hypothesis two is consistent with current dynamical understanding, as contained in high-resolution models.

The study explores the relationship between sea surface temperature (SST) and seasonal hurricane activity, and show how differing interpretations of the observational record can imply vastly different futures for Atlantic hurricane activity due to global warming. The two interpretations arise from assumptions of whether it is the local SST in the Atlantic in isolation, or whether it is the SST in the Atlantic 'relative' to the rest of the tropics, that drives variations in Atlantic hurricane activity.

Sea Urchin Yields Key Secret Of Biomineralization

The teeth and bones of mammals, the protective shells of mollusks, and the needle-sharp spines of sea urchins and other marine creatures are made-from-scratch wonders of nature.

Used to crush food, for structural support and for defense, the materials of which shells, teeth and bones are composed are the strongest and most durable in the animal world, and scientists and engineers have long sought to mimic them.

Sea urchin. The teeth and bones of mammals, the protective shells of mollusks, and the needle-sharp spines of sea urchins and other marine creatures are made-from-scratch wonders of nature.

Now, harnessing the process of biomineralization may be closer to reality as an international team of scientists has detailed a key and previously hidden mechanism to transform amorphous calcium carbonate into calcite, the stuff of seashells. The new insight promises to inform the development of new, superhard materials, microelectronics and micromechanical devices.

Bumblebee Colonies Which Are Fast Learners Are Also Better Able To Fight Off Infection

Bumblebee colonies which are fast learners are also better able to fight off infection, according to scientists from Queen Mary, University of London and the University of Leicester.

Dr Nigel Raine from Queen Mary's School of Biological and Chemical Sciences, and Akram Alghamdi, Ezio Rosato and Eamonn Mallon from the University of Leicester tested the learning performance and immune responses of bumblebees from twelve colonies.

The team tested the ability of 180 bees to learn that yellow flowers provided the biggest nectar rewards, and to ignore blue flowers. To test the evolutionary relationship between learning and immunity, they also took workers from the same colonies and tested their immune response against bacterial infection.

Rockport - Federal officials say a 2.7-magnitude earthquake struck Saturday night near the community of Magnet Cove in Hot Spring County.

The U.S. Geological Survey reports the earthquake hit three miles northeast of Rockport and five miles north-northeast of Malvern at 9 p.m. The USGS says the earthquake started about 3.1 miles underground.

Otto the octopus wreaks havoc

A octopus has caused havoc in his aquarium by performing juggling tricks using his fellow occupants, smashing rocks against the glass and turning off the power by shortcircuiting a lamp.

Staff believe that the octopus called Otto had been annoyed by the bright light shining into his aquarium and had discovered he could extinguish it by climbing onto the rim of his tank and squirting a jet of water in its direction.

Hailstorm of Ice and Followed by Rain of Lies

Comment: This is a story about a freak cold weather incident that is rather astonishing and at the end, to stave off reasonable doubt about global warming, which would creep into the mind of anyone who has been paying attention to the actual data regarding the state of our planet, someone decides to throw in some of the most ridiculous propaganda we have ever read considering the story that includes it.

Read and weep with despair at the lies being delivered to the public without a blush, and the public that doesn't immediately boycott all mainstream media in protest!

Hailstorm swamps one small town in 6ft drifts - and it's still only October

These astonishing scenes are the aftermath of a deluge of hailstones that buried a town in a river of ice.

Ottery St Mary, in Devon, was plunged into chaos by the storm in the early hours yesterday.

First, the area was battered by an astonishing 12in of hail in just two hours. This blocked drains, which led to widespread flooding as the rain began to fall.

More than 100 people had to be evacuated from their homes and 25 were airlifted to safety or rescued by firefighters.

US: Rare aftershocks persist in North Texas

Northern Texas has been getting more rare earth tremors, one day after several minor earthquakes made Halloween memorable for some people in the area.

Two almost simultaneous aftershocks were centered beneath Grand Prairie and Irving just before 7 a.m. Saturday. The U.S. Geological Survey says the Grand Prairie quake measured 2.5 magnitude and the Irving quake came in at 2.7.

A magnitude 6.0 earthquake struck Papua New Guinea today, about 691 kilometers (428 miles) northeast of the capital, Port Moresby, the U.S. Geological Survey said.

The temblor struck at 11:13 a.m. local time at the depth of 10 kilometers in the Bismarck Sea, the USGS said on its Web site. No tsunami warning was issued. A similar magnitude quake was also reported on Oct. 28, it said.
