Cancer cells accelerate aging and inflammation in the body to drive tumor growth

May 26, 2011

0

Researchers at the Kimmel Cancer Center at Jefferson have shed new light on the longstanding conundrum about what makes a tumor grow—and how to make it stop. Interestingly, cancer cells accelerate the aging of nearby connective tissue cells to cause inflammation, which ultimately provides “fuel” for the tumor to grow and even metastasize. This revealing […]

Fossil of giant ancient sea predator discovered

Paleontologists have discovered that a group of remarkable ancient sea creatures existed for much longer and grew to much larger sizes than previously thought, thanks to extraordinarily well-preserved fossils discovered in Morocco. The creatures, known as anomalocaridids, were already thought to be the largest animals of the Cambrian period, known for the “Cambrian Explosion” that […]

An international team of astronomers [1] has used ESO’s Very Large Telescope to carefully study the star VFTS 682 [2] in the Large Magellanic Cloud, a small neighbouring galaxy to the Milky Way. By analysing the star’s light, using the FLAMES instrument on the VLT, they have found that it is about 150 times the […]

The electron was hailed by British scientists Thursday as the roundest natural object in the universe. Researchers from Imperial College London conducted a decade-long laser experiment on the subatomic particle and discovered that it differs from a perfect sphere by less than 0.000000000000000000000000001 of a centimeter — so that “if the electron were magnified to […]

Astronomers Create Most Complete 3-D Map of Universe Ever

Astronomers have created the most complete 3-D map of our local universe, revealing new details about our place in the cosmos. The map shows all visible structures out to about 380 million light-years, which includes about 45,000 of our neighboring galaxies (the diameter of the Milky Way is about 100,000 light-years across).

Photographer Roger de la Harpe was in South Africa’s Tswalu Kalahari Game Reserve taking pictures for a book about the endangered African lion, when he spotted three lionesses on the path ahead. Placing a small digital video camera on the ground, he retreated to a safe distance. As planned, the lions approached the camera. However, […]

Bacteria-rich hailstones add to ‘bioprecipitation’ idea

May 26, 2011

0

P syringae bacteria are well-known “catalysts” for ice formation A study of hailstones has found large numbers of bacteria at their cores. The find lends credence to the “bio-precipitation” idea, which suggests that bacteria are actively involved in stimulating precipitation. The bacteria have protein coatings that cause water to freeze at relatively warm temperatures. Researchers […]

Cosmic distance record ‘broken’

May 26, 2011

A cataclysmic explosion of a huge star near the edge of the observable Universe may be the most distant single object yet spied by a telescope. Scientists believe the blast, which was detected by Nasa’s Swift space observatory, occurred a mere 520 million years after the Big Bang. This means its light has taken a […]

Seventeen lost pyramids are among the buildings identified in a new satellite survey of Egypt. More than 1,000 tombs and 3,000 ancient settlements were also revealed by looking at infra-red images which show up underground buildings. Initial excavations have already confirmed some of the findings, including two suspected pyramids. The work has been pioneered at […]
