Recently, researchers have found that prolactin is also produced by some tissues outside the brain, however little is known about the functions of extra-pituitary prolactin or how its production is regulated in these tissues. The PI3K-Akt oncogenic signaling pathway in the mammary glands of mice rapidly induces cells in the breast itself to produce prolactin, which leads to breast tissue differentiation, and prolactin has long been thought to play a role in breast cancer.

The NASA/ESA Hubble Space Telescope has provided another outstanding image of a nearby galaxy -- NGC 4183, seen with a beautiful backdrop of distant galaxies and nearby stars. Located about 55 million light-years from the sun and spanning about eighty thousand light-years, NGC 4183 is a little smaller than the Milky Way. This galaxy, which belongs to the Ursa Major Group, lies in the northern constellation of Canes Venatici (The Hunting Dogs).

NASA's Mars rover Opportunity, well into its ninth year on Mars, will work for the next several weeks or months at a site with some of the mission's most intriguing geological features. The site, called "Matijevic Hill," overlooks 14-mile-wide (22-kilometer-wide) Endeavour Crater. Opportunity has begun investigating the site's concentration of small spherical objects reminiscent of, but different from, the iron-rich spheres nicknamed "blueberries" at the rover's landing site nearly 22 driving miles ago (35 kilometers).

Terry Macalister is the energy editor of the Guardian. But when he took his son to an exhibition, he was shocked to see himself – on the cover of a punk fanzine from 25 years ago
You don't expect to walk in to the Hayward Gallery and come face to face with yourself. Especially not if the person glaring out at you is a punk rocker from 35 years ago. It reminded me that I have not always been a slightly grumpy energy editor. At one time I was an ill-tempered music writer who produced a fanzine – called Bored Stiff – with a couple of mates.
I had taken my son to an exhibition of punk graphics, Someday All The Adults Will Die!, on London's South Bank, because he had just opted to do art A-level. He liked the show in that take-it-or-leave-it teenage way, while being incredulous that anyone would put their own image on the front page of a magazine. "Even Rupert Murdoch doesn't do that," he sneered.
But I was sent spinning into a reverie of images from Crass, Burnt Offering and Kill Your Pet Puppy. When I got home I immediately tapped into Facebook the name of my co-publisher Kevin, whom I had lost contact with three decades ago. There was his picture: same spiky hair, national health specs and a strange smile. He told me he no longer does art or music but runs a wine shop in Massachusetts.
I was then on to Martin, with whom I traipsed to endless London gigs at the Roxy, Vortex and Camden Ballroom and went further afield with to see the Sex Pistols at the Middlesbrough Rock Garden. We had kept in sporadic touch as he traded in his plastic bondage pants for a City pinstripe. Martin works on backroom computers for one of those monumental banks that recently wrecked the economy. But he does that for the money and still gets his pleasure from printing up pictures, playing guitar and making clothes.
Along with the music and the politics – or at least attitude – the clothes were definitely part of it: going up to the Vivienne Westwood and Malcolm McLaren-run Seditionaries shop on the King's Road on a Saturday afternoon. But even then the gear was expensive – and I was unemployed. My attempts to make it as a drummer failed, first with Holloway-based Zero Zero, and then at one disastrous gig with acid punk outfit Moses and the Tablets.
I thought I had at least sorted out the pay thing when I landed a job as assistant store keeper in the fancy linen department of John Lewis on Oxford Street (not far from the Vortex). But I was cruelly ousted. Apparently I could not get on with the house rules about only female staff wearing earings.
I realised I might need to become a "proper" journalist – even if I couldn't get my mug easily on the front page.

Most of us don't think about tires much until we either get a flat or they wear out, and then the bite of up to $1,000 or more for all four corners sure gets our attention. Most of all, we don't think of tires as having anything at all to do with fuel economy, when in fact they make a big difference.

Faced with 6,000 job openings and a Congress unresponsive to admitting more skilled workers from overseas, Microsoft on Thursday offered what it hopes will be a twofer solution: charging employers hundreds of millions of dollars for the right to hire more foreigners and using the money for educational training to eventually fill those jobs with Americans.

The tension between new technology and individual privacy is as old as Silicon Valley. Each advance that allows or impels us to share information or seek windows into others' lives is scary at first. Often the fears blow over as benefits become clear - but there will be limits to the degree that privacy and civil liberties will be given up, and individuals should have a right to make the choice for themselves.

Combine the tree-ring growth record with historical information, climate records, and computer-model projections of future climate trends, and you get a grim picture for the future of trees in the southwestern United States. That's the word from a team of scientists from Los Alamos National Laboratory, the U.S. Geological Survey, the University of Arizona, and other partner organizations.

Over the last two decades, scientists have come to understand that the genetic code held within DNA represents only part of the blueprint of life. The rest comes from specific patterns of chemical tags that overlay the DNA structure, determining how tightly the DNA is packaged and how accessible certain genes are to be switched on or off.

Former Wham star cites 'major anxiety' after bout of pneumonia while on a concert tour last year
George Michael has cancelled the Australian leg of his tour owing to "major anxiety" following life-threatening pneumonia last year. In a statement, the singer said he would fulfil his UK dates before seeking treatment. "I have tried in vain to work my way through the trauma that the doctors who saved my life warned I would experience," he said on his website.
"They recommended complete rest and the type of post-traumatic counselling which is available in cases like mine, but I'm afraid I believed (wrongly) that making music and getting out there to perform for the audiences that bring me such joy would be therapy enough in itself."
The former Wham singer became ill in November hours before he was due to perform in Vienna and came close to death during a month in hospital.
Michael resumed the tour in Vienna earlier this month, donating 1,000 tickets to medical staff as a thank you for saving his life.
He told fans it was "great to be alive" as he returned to the stage after also performing at the Olympics closing ceremony in August.
Michael was due to play dates in Perth, Adelaide, Sydney, Melbourne, Brisbane and the Hunter Valley between 10 November and 1 December.
Michael, who celebrated his 30-year career in music in June, re-arranged his songs for a 40-piece orchestra for the tour, which sees him perform in a number of British cities next month.

The older we get, the weaker our immune systems tend to become, leaving us vulnerable to infectious diseases and cancer and eroding our ability to benefit from vaccination. Now scientists have found that blocking the action of a single protein whose levels in our immune cells creep steadily upward with age can restore those cells' response to a vaccine.
