Wandering Albatrosses Follow Their Nose

The first study of how individual wandering albatrosses find food shows that the birds rely heavily on their sense of smell. The birds can pick up a scent from several miles away, U.S. and French researchers have found.

"This is the first time anyone has looked at the odor-tracking behavior of individual birds in the wild using remote techniques," said Gabrielle Nevitt, professor of neurobiology, physiology and behavior at UC Davis and an author on the study with UC Davis graduate student Marcel Losekoot of the Bodega Marine Laboratory and Henri Weimerskirch of the Centre National de la Recherche Scientifique, France.

Evidence of pagan rituals involving swans and other birds in the Cornish countryside in the 17th century has been uncovered by archaeologists.

Since 2003, 35 pits at the site in a valley near Truro have been excavated containing swan pelts, dead magpies, unhatched eggs, quartz pebbles, human hair, fingernails and part of an iron cauldron.

Computer program decides what's considered attractive

Paris - To the likely dismay of those who argue beauty is in the eye of the beholder, biostatisticians said Wednesday they had devised a computer program to predict whether a face will be considered attractive.

The software crunches a mass of calculations on the geometry and symmetry of the face, including so-called "golden ratios" of proportions between the eyes, nose, ears and lips singled out in previous research into the mystery of beauty.

The team put the program through its paces in tests on 18 male and 18 female volunteers aged 19 to 61. The human guinea pigs were shown pictures of 420 people drawn from the general population, equally divided among men and women, and were asked to rate the faces for attractiveness on a scale of one to 10.

Renaissance chess master and the Da Vinci decode mystery

A masterpiece from the early literature of chess has recently resurfaced after being thought lost for five centuries.

The rediscovery of this book is of much more than scholarly or antiquarian interest, for it has been suggested that its chess puzzle diagrams were not only designed by Leonardo da Vinci, but also drawn by him and, the most tantalising prospect of all, perhaps even composed by him.

Ancient Graves Found in Greece

Athens, Greece - Greek workers discovered around 1,000 graves, some filled with ancient treasures, while excavating for a subway system in the historic city of Thessaloniki, the state archaeological authority said Monday.

Sun's Corona Is Both Hot And Kinky

Astrophysicists are having a heated debate over the wave structure of the Sun's Corona - a debate which may one day influence solar weather forecasting and the theory behind fusion reactors.

The Sun's core is about 6000 degrees C, but its outer layer, the Corona, which is filled with a strong magnetic field, is 200 to 300 times hotter.

Skeleton Of Sun's Atmosphere Reveals Its True Nature

The Sun's outer atmosphere or corona is incredibly complex, as shown in observations from space. It is also extremely hot, with a temperature of over a million degrees by comparison with that of the Sun's surface of only 6000 degrees.

Spring Is Aurora Season

What are the signs of spring? They are as familiar as a blooming daffodil, a songbird at dawn, a surprising shaft of warmth from the afternoon sun. And, oh yes, don't forget the aurora borealis. Spring is aurora season. For reasons not fully understood by scientists, the weeks around the vernal equinox are prone to Northern Lights. Canadians walking their dogs after dinner, Scandinavians popping out to the sauna, Alaskan Huskies on the Iditarod trail -- all they have to do is look up and behold, green curtains of light dancing across the night sky. Spring has arrived!

'Quantum Logic Clock' Rivals Mercury Ion As World's Most Accurate Clock

An atomic clock that uses an aluminum atom to apply the logic of computers to the peculiarities of the quantum world now rivals the world's most accurate clock, based on a single mercury atom. Both clocks are at least 10 times more accurate than the current U.S. time standard.

Fossilized Giant Rhino Bone Questions Isolation Of Anatolia, 25 Million Years Ago

Contrary to generally accepted belief, Anatolia[1] was not geographically isolated 25 million years ago (during the Oligocene epoch): this has just been demonstrated by researchers from the Laboratoire des Mécanismes et Transferts en Géologie (LMTG) (CNRS/ University of Toulouse 3/IRD) and the Paléobiodiversité et paléoenvironnements laboratory (CNRS/Muséum national d'histoire naturelle/University of Paris 6).
