A specimen of the Wollemi pine, an Australian conifer and one of the world's oldest tree species, has been donated to Bergianska Garden at Stockholm University in Sweden.

The Wollemi was discovered on September 10, 1994, in an isolated valley in Wollemi National Park in New South Wales, about 150 km northwest of Sydney. It is estimated to be about 200 million years old, from earth's Jurassic Period, so it was around even before the Australian continent was formed.Wollemi Pine sample

Great news for imbibers. A new study suggests that alcohol may protect against rheumatoid arthritis and more of it is better than less. The study says three glasses of wine, for example, has positive effects but 10 glasses a week is even better.

The innate immune response is the body's first line of defense against pathogen infection. Dr. Xin Li (University of British Columbia) and colleagues report that three proteins work together in the MOS4-associated complex (MAC) to execute innate immunity in the mustard weed, Arabidopsis.

It may sound counterintuitive to use a microbial protein to improve water quality but some bacteria are doing just that to protect themselves from potentially toxic nanoparticles in their own environments, and clean up crews of the future could potentially do the same thing on a larger scale.

At some level, all types of matter that we usually deal with have at least one thing in common - they're made of particles. The solids, liquids, gases and plasmas that surround us are built of atoms, which are made of electrons, protons and neutrons. Protons and neutrons in turn are made of quarks.

A method for increasing plants’ tolerance to salt stress and thus preventing stunted growth and even plant death has been developed. The method has significant consequences for dealing with soil salinization, which is an acute problem for a wide range of crops in many regions of the world. Magnified photo at left shows the invasion of heavy oxidation (green bubbles) in the membrane of a wild, stressed, salt-sensitive plant.

Physicists of the DZero experiment at the Department of Energy's Fermi National Accelerator Laboratory have discovered a new heavy particle, the Îb(pronounced "zigh sub b") baryon, with a mass of 5.774±0.019 GeV/c2, approximately six times the proton mass.

If you've ever thought about running a public company, Sarbanes-Oxley is something you probably dread. Commonly dubbed "The Enron Law", it requires enormous oversight paperwork with the consequence that Chairmen, CEOs and Directors can go to jail if they violate it. A new University of Georgia study finds that the 2002 law has altered the makeup of corporate boards, making them larger and more independent and also had the unintended effect of increasing director pay - by more than 50 percent.

Even Nazca booby families don't stay together after the kids leave the nest these days. The Nazca booby is a long-lived seabird found in the Galapagos Islands off the coast of Ecuador.

Using a robotic telescope at the ESO La Silla Observatory, astronomers have for the first time measured the velocity of the explosions known as gamma-ray bursts. The material is travelling at the extraordinary speed of more than 99.999% of the velocity of light, the maximum speed limit in the Universe.

Quantum entanglement is one of the many non-intuitive features of quantum mechanics. If two photons of light are allowed to properly interact with one another, they can become entangled. One can even directly create pairs of entangled photons using a non-linear process called SPDC (Spontaneous Parametric Down Conversion).

A remarkable new long-necked, gliding reptile discovered in 220 million-year old sediments of eastern north America has been discovered, scientists report. Mecistotrachelos apeoros (meaning "soaring, long-necked") is based on two fossils excavated at the Solite Quarry that straddles the Virginia-North Carolina state line.CLICK ABOVE FOR FULL SIZE.Image of Mecistotrachelos apeoros.

The "snows" of Africa's Mount Kilimanjaro inspired the title of an iconic American short story, but now its dwindling icecap is being cited as proof for human-induced global warming.

The potential for gun shows to serve as places where criminals obtain firearms can be curbed through increased regulation without adversely affecting attendance or business, according to a new study.

The study, based on field observations made by Garen J. Wintemute, director of UC Davis’ Violence Prevention Research Program, also found that undocumented gun sales between private parties and illegal “straw purchases” in which a person with a clean record buys a weapon for someone with a criminal record were much more common at gun shows in states with little regulation.

Rome's Mayor Walter Veltroni will officiate at the first public viewing of "Rome Reborn 1.0," a 10-year project based at the University of Virginia and begun at UCLA to use advanced technology to digitally rebuild ancient Rome.

“Rome Reborn 1.0" shows almost the entire city within the 13-mile-long Aurelian Walls as it appeared in A.D. 320. At that time Rome was the multicultural capital of the western world and had reached the peak of its development with an estimated population of one million.Digital video of the Colosseum.
