Combining diamond anvils and powerful lasers, laboratory researchers have developed a technique that should be able to squeeze materials to pressures 100 to 1,000 times greater than possible today, reproducing conditions expected in the cores of supergiant planets.

Until now, these pressures have only been available experimentally next to underground nuclear explosions.

There is renewed hope for treatment of a rare genetic condition, Progeria, that causes rapidly accelerated aging and leads to an average life expectancy of 13 years.

Scientists studying the genes of two infants who died of mysterious illnesses found the infants had mutations in LMNA, the same gene altered in patients with the premature aging condition. But the infants' unusual mutations caused them to make many more bad copies of the gene's primary protein, lamin A, than progeria patients.

Great Tits are, of course, songbirds - specifically Parus major. An international team of researchers have now found evidence for the existence of a "curiosity-gene" in our feathered friends.

The gene (Drd4) carries the building instructions for a receptor in the brain, which forms the docking station for the neurotransmitter dopamine. Birds with a specific variant of this dopamine receptor D4 gene show a stronger exploratory behaviour than individuals with other variants.

New observations by the NASA/ESA Hubble Space Telescope have overturned conventional ideas about the early life of some massive globular clusters, showing that they can go through several periods of intense stellar formation rather than the previously accepted single burst. The analysis of Hubble data from the massive globular cluster NGC 2808 provides evidence that star birth occurred over three generations early in the cluster's life.

This NASA/ESA Hubble Space Telescope image of a dense swarm of stars shows the central region of the globular cluster NGC 2808. Astronomers were surprised when Hubble spied three generations of cluster stars.

I just got an invitation to attend Science Foo Camp in August 07, a unique meeting organized by Nature, O'Reilly and Google. Based on what I heard from last year's attendees this will be an amazing opportunity to bounce ideas around. I'd like to hear more from others who are going or who attended last year.

As before, we will be inviting around 200 people who are doing particularly interesting work in a wide range of scientific disciplines, as well as in areas of technology and culture that influence, and are influenced by, science. The aim is to encourage cross-fertilization of ideas, creating a unique opportunity to explore topics that transcend traditional boundaries.

Collaborative research between scientists in the UK and USA has led to a major breakthrough in the understanding of antiferromagnets, published in this week's Nature. Scientists at the London Centre for Nanotechnology, the University of Chicago and the Center for Nanoscale Materials at Argonne National Laboratory have used x-rays to see the internal workings of antiferromagnets for the very first time.

By observing changes in coherent X-ray speckle pattern, such as the one shown above, researchers are able for the first time to investigate nanoscale dynamics of antiferromagnetic domain walls, and observe a cross over from classical to quantum behavior. Credit: O.

When it comes to studying energy transfer in photosynthesis, it's good to think "outside the bun."

That's what Robert Blankenship, Ph.D., professor of biology and chemistry in Arts & Sciences at Washington University in St. Louis, did when he contributed a protein to a study performed by his collaborators at Lawrence Berkeley National Laboratory and the University of California at Berkeley. The protein's moniker? The taco shell protein.

By monitoring changes in vibrations of bridges it is possible to identify hidden cracks and fractures, according to a Queensland University of Technology researcher.

QUT engineering researcher Henry Shih said variations in bridge vibrations of a bridge could be a telling sign of its structural "health".

Breastfeeding and the good fats in Omega-3 fatty acids help new moms fight depression, according to new review.

The review was authored by Kathleen Kendall-Tackett, a health psychologist and researcher at UNH's Crimes against Children Research Center. Kendall-Tackett presents her findings in the article "A New Paradigm for Depression in New Mothers: The Central Role of Inflammation and How Breastfeeding and Anti-Inflammatory Treatments Protect Maternal Mental Health." The full article is available at http://www.internationalbreastfeedingjournal.com/content/2/1/6.

"Depression in new mothers is common in many cultures, affecting anywhere from 10 percent to 20 percent of postpartum women. In some high-risk populations, the percentage can even be as high as 40 percent or 50 percent.

Engineers at Washington University in St. Louis have developed a unique photocatlytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst.

The group is developing novel methodologies for synthesis of nanostructured films with superior opto-electronic properties. One of the methods, which sandwiches three semiconductor films into a compact structure on the nanoscale range, is smaller, more efficient and more stable than present photocatalytic methods which require multiple steps and can take from several hours to a day to complete.
