MRSA 'superbug' is found in British milk
A new strain of MRSA has been discovered in British milk, scientists report today.
The superbug, resistant to antibiotics, has been isolated from samples of milk taken from farms around the country and has also infected humans. It is the first time MRSA has been found in farm animals in the UK.
Experts said that as virtually all milk sold in Britain is pasteurised, drinking it or eating dairy products was "not a health concern". Meat was also unlikely to be affected, but any MRSA present would be destroyed in cooking anyway.
The "main worry" was that the bacteria might colonise people who work on farms, who might then transmit it to the wider community.
The revelation triggered immediate protests over intensive farming and the use of antibiotics in livestock. The Soil Association demanded an end to routine antibiotic use in dairy farming and the introduction of comprehensive tests for MRSA of farm animals, farm workers, milk and meat.
The first human case of infection with the new strain was found in Cambridge in 2009. Since then 12 cases have been identified in Scotland, 14 in England and 24 in Denmark. Most were carriers of the bacterium, but in some it caused serious infection of the blood, wounds or skin. Infections with MRSA are treatable but cause more severe illness, require stronger antibiotics and take longer to resolve.
The discovery is the result of a chance finding by researchers at the University of Cambridge, who were investigating mastitis in cows, an infection of the udder. Their results, published in The Lancet Infectious Diseases, show cases of the new strain are increasing but account for less than 1 per cent of all human MRSA detections. Less than 3 per cent of dairy herds are thought to be affected.
Mark Holmes of the Department of Veterinary Medicine at the University of Cambridge, who led the study, said: "It is still not known for certain if cows are infecting people, or people are infecting cows. This is one of the things we will be looking into next."
Asked if the routine use of antibiotics in livestock farming was a factor in the emergence of the new MRSA strain, he said it was a "credible hypothesis".
"Farmers are under tremendous financial pressure from the super- markets. It does mean they are the most efficient milk producers but that means they have more mastitis and use more antibiotics," he said.
Why Apple Enthusiasts Are Wrong About Windows 8
On Wednesday evening, Microsoft showed the first public glimpses of Windows 8, including a touch screen interface that's unlike any version of Windows we've ever seen. And already, Apple enthusiasts are chiming in with disdain.
Microsoft just doesn't get it, they say. Windows 8 drops the ball by supporting both tablet and legacy Windows applications, instead of throwing everything out and starting a new tablet OS from scratch. The iPad is so perfect because it doesn't try to be a Mac, they argue. Letting people run Excel on a tablet just isn't "elegant." No, it's a fundamentally flawed understanding of what makes Apple's tablet so magical and revolutionary, they protest.
Baloney. Microsoft doesn't have to copy Apple's strategy for Windows 8 to succeed. In fact, copying Apple would be a fatal mistake. Instead, Microsoft should be charting new territory with Windows 8, and that's exactly what's happening.
In supporting the old, familiar Windows interface and the new tablet experience on a single device, Microsoft has laid the groundwork for modular computing -- that is, a single device that transforms to suit the user's needs. Want to lounge around with some e-books or videos? The tablet interface makes it possible. Want to get some work done? Plug in a mouse and keyboard and go crazy with the desktop version of Excel. It's the best of both worlds in one piece of hardware.
At Macworld, Jason Snell argues that this is a risky approach. If the iPad ran Mac apps, he says, developers probably wouldn't have bothered creating all-new apps for the touch screen. I'm not convinced that the same will be true for Windows 8, with its huge potential customer base. There will be demand for touch-based apps simply because of how many people are already using Windows. And besides, Microsoft has proven willing to grow its app ecosystem by paying developers.
I also don't buy the idea that Microsoft needed to show a version of Office built from the ground-up for tablets, as John Gruber argues. While it'd be nice if Microsoft created touch-based versions of its productivity software -- and don't rule it out just yet -- there's only so much work you can do with a touch screen. Trust me, I've tried to blog on my iPad countless times, but I can never get farther than tapping out a rough draft and switching to a laptop to finish the job. It's not just the mouse and keyboard that makes the difference. It's the little things, like keyboard shortcuts, right clicks and easy access to a file manager.
What Microsoft demonstrated on Wednesday is exactly what I want in a computer -- a lightweight tablet UI that's meant for casual computing and a powerful, classic Windows that allows me to work. I'm tired of carrying around my iPad and laptop together. I want one device that does everything.
That's not to say Microsoft will pull it off. The company has set some ambitious goals for Windows 8, and a lot can go wrong. But I'm not about to dismiss what Microsoft is doing because it doesn't follow in Apple's footsteps. For Microsoft, playing copycat would only solidify Apple's lead in the post-PC era.

Deep Magma Ocean Fuels Hundreds of Volcanoes on Jupiter Moon
There's a deep ocean of magma lurking beneath the crust of Jupiter's moon Io, a new study says.
Only slightly larger than Earth's moon, Io is the most volcanically active body in the solar system. The discovery solves a long-standing debate over how much of the moon's insides must be molten to feed the ongoing eruptions.
"At any time, Io has 400 [and] maybe more active volcanoes," said study leader Krishan Khurana, a planetary physicist at the University of California, Los Angles.
"They are very powerful—they can shoot plumes out into space to a height of about 300 miles [500 kilometers]." Finding an extensive magma ocean means that "now we know why there are so many, and where the lava comes from."
(Related: "'Super Earth' May Really Be New Planet Type: Super-Io.")
Jupiter Probe Worked Like Airport Scanners
Khurana and colleagues made the find after reexamining readings from the Galileo spacecraft, which orbited Jupiter from 1995 to 2003 and made occasional flybys of the planet's moons, including Io.
The data showed how Io deflects Jupiter's enormous magnetic field via a process called electromagnetic induction—"very similar to the principle used by the metal detectors at the airport," Khurana said.
Magma has high electrical conductivity, he explained, a trait that laboratory studies have demonstrated with molten rocks similar to those expected to lie beneath Io's surface.
As Jupiter's electromagnetic field penetrates Io, it interacts with the magma ocean, and a current forms on the outer edge of the molten rock layer. This current in turn generates its own electromagnetic waves, which deflect Jupiter's field lines, an effect the Galileo probe was able to detect.
The data show that Io's magma exists in an underground layer that lies about 20 to 30 miles (30 to 50 kilometers) beneath the surface, between the crust and the mantle.
The magma layer is at least 30 miles (50 kilometers) thick, and it might be as thick as 200 miles (320 kilometers).

Moon's Magma a Slushy Mix?
Also, the magma probably isn't completely liquid, Khurana said. Rather, it has the consistency of slushy ice, with a mix of molten rock and crystals.
This hot slush is created by tidal forces from the mammoth gravity of Jupiter, which slowly knead the moon as it moves in its orbit, generating enormous amounts of heat as rock crystals rub against each other.
Once formed, the magma ocean would concentrate tidal energy inside itself, keeping the layer toasty: "A slushy magma ocean is a perfect place for heating from friction," Khurana said.
(Related: "Could Jupiter Moon Harbor Fish-Size Life?")
The discovery wasn't made earlier because Io's volcanoes emit large quantities of ionized gases, which also interact with Jupiter's magnetic field, he added.
It took until now for scientists to produce good enough computer models to pierce though this interference and spot the additional effect of the magma ocean.

Hikmah Pagi: Tertutupnya Pintu Tobat
Sebusuk apapun maksiat yang telah dilakukan, sebanyak apapun dosa yang telah diperbuat, bila manusia kembali kepada jalan Allah, maka Allah SWT akan menerima tobatnya. Bahkan terhadap orang yang kafir sekalipun, bila ia memeluk agama Islam, Allah akan mengampuni segala dosanya.
Pintu tobat senantiasa terbuka. Dan Allah SWT akan senantiasa menanti kedatangan hamba-Nya yang akan bertaubat. Namun demikian, tidak selamanya pintu tobat terbuka ada saatnya pintu tobat tertutup rapat.
Pintu tobat akan tertutup rapat pada dua keadaan; pertama, ketika nyawa manusia sudah berada di tenggorokan. Rasulullah SAW bersabda, “Sesungguhnya Allah Yang Mahamulia lagi Mahaagung menerima tobat seseorang sebelum nyawanya sampai di tenggorokan.” (HR Tirmidzi)
Kedua, ketika matahari terbit dari tempat terbenamnya. Rasulullah SAW bersabda, “Barangsiapa bertobat sebelum matahari terbit dari barat, niscaya Allah menerima taubatnya." (HR Muslim)
Tertutupnya pintu tobat merupakan batas dimana penyesalan, permohonan ampun, perbuatan baik dan keimanan orang kafir tidak bermanfaat lagi, karena Allah SWT tidak menerimanya.
Allah SWT berfirman, “Yang mereka nanti-nanti tidak lain hanyalah kedatangan malaikat kepada mereka (untuk mencabut nyawa mereka), atau kedatangan Tuhanmu atau kedatangan sebagian tanda-tanda Tuhanmu. Pada hari datangnya sebagian tanda-tanda Tuhanmu tidaklah bermanfaat lagi iman seseorang bagi dirinya sendiri yang belum beriman sebelum itu, atau dia (belum) mengusahakan kebaikan dalam masa imannya. Katakanlah: "Tunggulah olehmu sesungguhnya kami pun menunggu (pula)." (Q S Al-An’am [6]: 158)
Hal ini harus menjadi perhatian kita untuk tidak menunda-nunda untuk bertaubat, bila hal ini terjadi besar kemungkinan akan menenggelamkan kita pada kemaksiatan dan pada akhirnya akan menganggap baik bahkan bangga dengan kemaksiatan yang dilakukannya.
Selagi kita hidup didunia, mari kita gunakan kesempatan ini untuk menyikapi adanya penutupan pintu taubat ini dengan cara: Pertama, bersegera melakukan taubat. Allah SWT berfirman, “Sesungguhnya tobat di sisi Allah hanyalah tobat bagi orang-orang yang mengerjakan kejahatan lantaran kejahilan, yang kemudian mereka bertobat dengan segera, maka mereka itulah yang diterima Allah tobatnya; dan Allah Maha Mengetahui lagi Maha Bijaksana.” (QS An-Nisa [4]: 17)
Kedua, bersegera melakukan berbagai macam kebaikan sebelum datangnya masa yang menyebabkan kita sulit untuk melakukan kebaikan. Rasulullah saw. bersabda, “Bersegeralah kalian untuk mengerjakan amal-amal saleh, karena akan terjadi berbagai fitnah yang menyerupai malam yang gelap gulita..” (HR Muslim dan Tirmidzi)
Ketiga, berusaha meningkatkan ketakwaan kepada Allah SWT. Dengan takwa kita akan diberi kemampuan untuk membedakan yang benar dan salah. (QS Al-Anfaal [8]: 29)
