The Pakistani schoolgirl Malala Yousafzai, who was shot by the Taliban for campaigning for education for girls, was discharged yesterday from the Queen Elizabeth hospital in Birmingham, England after success in the first stage of her medical treatment.

In October, Yousafzai was shot by Taliban forces on a school bus in Mingora, Swat District, Pakistan. She was given emergency treatment in Pakistan and then flown to Britain for treatment at a specialist unit which deals with injured soldiers.

Dave Rosser, University Hospitals Birmingham NHS Foundation Trust medical director, gave a statement about Yousafzai’s release from hospital: “Malala is a strong young woman and has worked hard with the people caring for her to make excellent progress in her recovery. Following discussions with Malala and her medical team, we decided that she would benefit from being at home with her parents and two brothers. She will return to the hospital as an outpatient and our therapies team will continue to work with her at home to supervise her onward care.”

She is due to return to hospital in a few weeks for cranial reconstructive surgery.

A man and his wife, aged 87 and 84, have died after a car hit them in North Ayrshire in Scotland. The couple, who have yet to be publicly identified, were walking across Greenock Road in the town of Largs when they were hit by a red Toyota at approximately 9:15am BST (0815 UTC) yesterday.

An air ambulance reportedly attended the scene of the crash. The woman was taken to Southern General Hospital in Glasgow. She died several hours later. Her husband died at the crash site. The Toyota driver, a 34-year-old woman, was uninjured but as a precaution was taken to Inverclyde Royal Hospital.

Greenock Road was closed between Nelson Street and Brisbane Road following the incident but reopened around 4:00pm BST (1500 UTC) yesterday. A report about the incident is to be sent to the procurator fiscal. Police have appealed for potential witnesses to the accident to contact them.

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.

The U.S. Army installation at Fort Lee in Virginia will begin using a program called RAPIDGate that will replace passes issued to non-military persons who regularly require access to the facility. The program will take effect July 10, when the practice of issuing 90-day passes to people who present a valid driver’s license, vehicle registration, and proof of insurance for the vehicle used for access ends. Those passes will be grandfathered out as they expire.

The RAPIDGate program for fast entry into Fort Lee replaces what was once access privileges performed by the installation itself, which came free of cost. The new outsourced program administered by Portland, Oregon-based Eid Passport, Inc. enhances security to the installation by performing background checks. Their service comes at a price. The screening process makes a ten-year felony background check, performs a check against terrorist and sexual offender watch lists, and does a social security cross reference to validate a person’s identity.

Qualified applicants are issued a pass that enables them to bypass inspection pits and use any of the facility’s seven gates for access. Businesses whose employees would benefit by this are required to contact the program provider and have “point of contact” persons who can validate an applicant’s employment. Enrollment in the program costs the business US$199. A pass for each employee of the business costs $159 annually. The pass for employees expires after a year, when a new background check is required by the program.

The program is a voluntary alternative for civilians to conform with new access policies mandated by the Department of Defense and the U.S. Army, according to an information pamphlet distributed by the base. A kiosk will be set up at Fort Lee to accept applications that process a photograph, social security number, and fingerprint.

Those without a RAPIDGate pass will need to enter the fort at locations where their vehicle can be inspected. A rigorous inspection involves armed guards asking the driver to place keys on the dash board, pop the hood and the trunk, open the glove box, and have all occupants exit the vehicle and open all doors, including the hood and trunk. While the vehicle is inspected inside, another guard uses a mirror attached to a wand to inspect under the chassis of the vehicle’s undercarriage.

Eid Passport, Inc. specializes in identity authentication and background screening. Fort Lee will be the 12th military installation out of an estimated 250 military installations on U.S soil to implement identity screening as part of new policies mandated by the Department of Defense (DoD).

“The pass contains no personal information,” said David Smith, the director of marketing for Eid Passport. It does contain a barcode which is scanned at entry. The RAPIDGate program database includes a biometric fingerprint that might be checked by the scanning device against the presenter of the pass in times of elevated security. The pass is also embedded with an active RFID transmitter. The pass is scanned on entry to the fort at the gate check point, but not upon exit. If the RFID transmitter works properly, movement into and out of the base will be recorded.

The Fort Lee pamphlet mentions a “a new mandate” by the DoD. That mention appears to be in reference to portion of the language found in an Instruction issued in October last year by the DoD that states, “Implement a verification process, whether through background checks or other similar processes, that enables the U.S. Government to attest to the trustworthiness of DoD contractors and sub-contractors.”

The Instruction stems from a Directive signed by President Bush in August of 2004. That Directive, from the Department of Homeland Security, says in part, “Wide variations in the quality and security of forms of identification used to gain access to secure Federal and other facilities where there is potential for terrorist attacks need to be eliminated.”

Fort Lewis in Washington state was the first U.S. military installation to adopt the RAPIDGate program as a test in 2004. Since then, Fort Sam Houston, Fort Carson, and Fort Bragg, among other installations have adopted the program.

“What happened at Fort Dix, [New Jersey], as we look at it, is a Fort Dix issue,” Laura Arenschield reported spokesman for the 18th Airborne, Tom McCollum, as saying in June. “That should not be taken as an invitation for someone to try it here at Fort Bragg, but (security) is a living, breathing entity. You have to constantly change it just to keep those who are trying to penetrate it on their toes.” The new security measures will go into effect at Fort Bragg, North Carolina, which is among the largest of domestic military bases, starting July 8.
