Astronaut Mike Hopkins works outside the International Space Station during a spacewalk, yesterday, in this image from a video courtesy of Nasa. - Reuters pic, December 25, 2013.Two Nasa astronauts wrapped up successful repairs at the International Space Station yesterday after a rare Christmas Eve spacewalk to fix an equipment cooling system.

Americans Rick Mastracchio, 53, and Mike Hopkins, 44, floated outside the orbiting lab for seven and a half hours to replace an ammonia pump whose internal control valve failed on December 11.

"We have a pump that is alive and well," said Nasa commentator Rob Navias on the US space agency's live television feed after a successful jumpstart test on the newly installed pump module, a bulky piece of gear the size of a refrigerator.

More checks need to be done, but the pump appeared to be "in good shape" and would be fully activated in the coming hours, Navias said from mission control in Houston.

Despite recent concerns about leaking spacesuits, neither astronaut reported any problems.

The suits "have functioned perfectly and have been bone dry throughout the course of today's spacewalk," Navias said.

Hopkins, making his second career spacewalk, rode the 15-metre robotic arm, operated from inside the station by Japanese astronaut Koichi Wakata.

With his boots affixed to the Canadian-made arm, Hopkins grasped the bulky pump module as Wakata maneuvered him over to its installation location.

Then, Mastracchio, who was making his eighth career spacewalk, helped push the module into its slot and the pair began affixing it in place.

NASA Recreates Picture That Changed the World

The first men to orbit the moon knew they were on an epic journey, but they never imagined the impact of a single image

If you had your druthers during Christmas week 1968, youd have wanted to get as far away from Earth as possible. The entire planet was a messsoutheast Asia was in flames, Czechoslovakia was living under a Soviet crackdown, Bobby Kennedy and Martin Luther King had been murdered and cities across the country had been torn by rioting.

As it happened, three men out of the 3.5 billion human beings then at large did have the chance to get out of Dodge, and so, on the morning of December 21, the crew of Apollo 8Frank Borman, Jim Lovell and Bill Andersclimbed atop their Saturn V rocket and set out for humanitys first manned mission to orbit the moon. For a trip that began with nothing short of an act of chemical violence7.5 million lbs (3.4 million kg) of thrust exploding out of the bottom of a 36-story rocket, accelerating the crew to an escape velocity of 25,000 mph (40,000 k/h)the actual moonward coast was a rather lazy thing.

For three days, the astronauts would drift away from the planet, their speed steadily slowing as the Earth tugged inexorably back on them. Finally, 80% of the way to the moon, lunar gravity would take over, speeding them up and pulling them in. Until the critical moment when theyd fire their engine to ease themselves into lunar orbit, they had comparatively little to do, and so, on the morning of Dec. 22, when they were 104,000 mi. (167,000 km) from home, Houston radioed up with the days headlines.

Let me know when it gets to be breakfast time, said the Capsule Communicator (Capcom) in Mission Control. Ive got a newspaper to read up to you.

Good idea, said Borman. We never did get the news.

TIMEs Jan. 3, 1969 issue, showing Men of the Year Apollo 8 astronauts William A. Anders, Frank Borman and Jim Lovell.

You are the news, the Capcom answered. The flight to the moon is occupying prime space on both newspaper and television. In other news, eleven GIs that have been detained five months in Cambodia were released yesterday and will make it home for Christmas. David Eisenhower and Julie Nixon were married yesterday in New York; he was described as nervous. The Browns took Dallas apart yesterday 31 to 20, and were sort of curious: Who do you like today, Baltimore or Minnesota?

Baltimore, Lovell answered. (History records that he was right: the Colts beat the Vikings 24 to 14.)

Mighty nice view from out here, Borman said peacefully.

NASA astronauts on critical Christmas Eve spacewalk

News

December 24, 2013 11:48 AM ET

Two NASA astronauts are on a rare Christmas Eve spacewalk outside the International Space Station, working to replace a pump that caused a cooling malfunction on the orbiter.

This is the second spacewalk in four days for the two astronauts. On Saturday, NASA flight Engineers Rick Mastracchio and Mike Hopkins removed a malfunctioning pump from the outside of the space station.

With that part of the job complete, Mastracchio and Hopkins are replacing the degraded ammonia pump module on the station's starboard truss with a new one.

They left the station to begin their efforts at 6:53 a.m. ET today. Ground engineers expect the spacewalk to continue until about 12:30 p.m.

Three hours into the spacewalk, the two astronauts began to install the 780-pound replacement pump.

Hopkins, attached to the end of the station's robotic arm, grabbed hold of the new, refrigerator-sized pump and, with Japanese astronaut Koichi Wakata guiding the robotic arm from inside the station, maneuvered the pump into place.

The astronauts may go out on another spacewalk on Christmas Day if there is still work to be done to get the station's cooling system running fully again.

Hopkins, making his second career spacewalk, rode the 57-foot (15-meter) robotic arm, operated from inside the station by Japanese astronaut Koichi Wakata.

With his boots affixed to the Canadian-made arm, Hopkins grasped the bulky pump module as Wakata maneuvered him over to its installation location.

Then, Mastracchio, who was making his eighth career spacewalk, helped push the module into its slot and the pair began affixing it in place.

Five electrical connections and four fluid connections followed, and a brief test, like a jumpstart, was done to test the pump's connections and electronics.

NASA spacewalkers install new station cooling pump

CAPE CANAVERAL, Florida - Two NASA astronauts spent more than seven hours working outside the International Space Station on Tuesday and successfully repaired a critical cooling system.

It was the second spacewalk in three days for flight engineers Rick Mastracchio and Mike Hopkins, who wrapped up the cumbersome work with only one problem.

As they were installing a spare cooling pump, a sprinkling of ammonia crystals leaked out from one of four fluid lines. The toxic liquid turns to flakes in the cold and weightlessness environment of space.

The astronauts spent an extra 15 minutes in the station's Quest airlock to bake out any potential residue on their spacesuits. The 7.5-hour spacewalk was broadcast live on NASA Television.

"It took a couple of licks to get her done, but we got it," Hopkins radioed to flight controllers at NASA's Mission Control Center in Houston.

The new pump will not be fully tested until later on Tuesday, but an initial check in the final hour of the spacewalk showed it was "alive and well," reported NASA mission commentator Rob Navias.

During a spacewalk on Saturday, the astronauts removed a failed cooling system pump and attached it to a temporary storage site at the base of the station's mobile rail cart.

NASA is considering a potential future spacewalk to repair the refrigerator-size pump and use it as a spare, officials said.

In addition to the new pump installed on Tuesday, there are two other spare pumps aboard the station, a $100 billion research complex that flies about 260 miles above Earth.

The U.S. side of the station, which includes Japanese and European laboratories, has been without half its cooling system since December 11 when a valve failed inside a pump.

Impact of nanotechnology – Wikipedia, the free encyclopedia

The impact of nanotechnology extends from its medical, ethical, mental, legal and environmental applications, to fields such as engineering, biology, chemistry, computing, materials science, and communications.

Major benefits of nanotechnology include improved manufacturing methods, water purification systems, energy systems, physical enhancement, nanomedicine, better food production methods and nutrition and large scale infrastructure auto-fabrication.[vague] Nanotechnology's reduced size may allow for automation of tasks which were previously inaccessible due to physical restrictions, which in turn may reduce labor, land, or maintenance requirements placed on humans.

Potential risks include environmental, health, and safety issues; transitional effects such as displacement of traditional industries as the products of nanotechnology become dominant, which are of concern to privacy rights advocates. These may be particularly important if potential negative effects of nanoparticles are overlooked.

Whether nanotechnology merits special government regulation is a controversial issue. Regulatory bodies such as the United States Environmental Protection Agency and the Health & Consumer Protection Directorate of the European Commission have started dealing with the potential risks of nanoparticles. The organic food sector has been the first to act with the regulated exclusion of engineered nanoparticles from certified organic produce, firstly in Australia and the UK,[1] and more recently in Canada, as well as for all food certified to Demeter International standards[2]

Nano optimists, including many governments, see nanotechnology delivering benefits such as:

Potential risks of nanotechnology can broadly be grouped into four areas:

The presence of nanomaterials (materials that contain nanoparticles) is not in itself a threat. It is only certain aspects that can make them risky, in particular their mobility and their increased reactivity. Only if certain properties of certain nanoparticles were harmful to living beings or the environment would we be faced with a genuine hazard. In this case it can be called nanopollution.

In addressing the health and environmental impact of nanomaterials we need to differentiate between two types of nanostructures: (1) Nanocomposites, nanostructured surfaces and nanocomponents (electronic, optical, sensors etc.), where nanoscale particles are incorporated into a substance, material or device (fixed nano-particles); and (2) free nanoparticles, where at some stage in production or use individual nanoparticles of a substance are present. These free nanoparticles could be nanoscale species of elements, or simple compounds, but also complex compounds where for instance a nanoparticle of a particular element is coated with another substance (coated nanoparticle or core-shell nanoparticle).

There seems to be consensus that, although one should be aware of materials containing fixed nanoparticles, the immediate concern is with free nanoparticles.

Nanoparticles are very different from their everyday counterparts, so their adverse effects cannot be derived from the known toxicity of the macro-sized material. This poses significant issues for addressing the health and environmental impact of free nanoparticles.

Nanotech venture goes global

A Cambridge UK nanotechnology company has started shipping product globally and has strengthened its management to bolster the international scale-up.

Ionscope manufactures Scanning Ion Conductance Microscopes (SICMs) for imaging living cells. SICMs are used by neurological and cardiac scientists to understand fundamental processes associated with diseases and therapeutics, because of the unique combination of nano-scale topographical and physiological information they provide.

Ionscope has built a user base in laboratories around the world, and we are committed to building on this base as we expand into new areas, says Ionscope chairman Dr David Cleevely.

Material scientists are also using Ionscopes products to see nano-scale changes in battery electrodes during charging and discharging. Understanding this charging cycle is highly important for increasing the battery capacity and lifetime in mobile phones and electric vehicles.

As in living cells, the ability of SICM to monitor changes whilst the battery is operating has attracted the attention of top European and American researchers.

I have been involved in nanotechnology and analytical instrumentation for over 20 years now, says Dr Hills who previously helped to mould Cambridge life science business Pneumacare into a commercial venture.

Its clear to me that Ionscopes products have real potential to become an important part of surface science in very difficult environments.

Dr Hills trained as an analytical chemist with early experience in instrument development, electrochemistry and the energy sector working for both the US and Japanese governments.

He co-founded networks dedicated to the advancement of stem cell and micro-nanotechnology, and has gone on to lead several companies to win business internationally.

Dr Richardson added: Nanotechnology is a hugely exciting industry that is expanding rapidly. I am pleased to have the opportunity to contribute in the R & D of current and future Ionscope products and to become involved in this industry with one of its leaders.

Nanotechnology Helps Measurement of Toxic Heavy Metals in Foodstuff

technology Helps Measurement of Toxic Heavy Metals in Foodstuff -->

TEHRAN (FNA)- Iranian researchers measured very tiny amounts of some of toxic heavy metals in water and foodstuff by using SBA-15 nanoporous compound functionalized with guanidin groups as perfect sorbent for metals.

In the first stage of the research, SBA-15 nanoporous compound functionalized with guanidin was prepared and its structural properties were investigated. In the next stage, the compound was used for the extraction and preconcentration of some of heavy metals that are classified among toxic and hazardous elements for the living creatures and environment, and as a result, it made possible the measurement of very small amounts of the elements. Finally, the concentration of lead, copper, cadmium, and zinc ions were measured in various water and food samples, and promising results were obtained. Nanopores in the structure of SBA-15 increase the interface of sorbent with the solution, and therefore, ion sorption capacity increases on this compound. Besides, the high regularity and homogeneity of the nanopores result in excellent repeatability of the extraction process. Nanoporous SBA-15 functionalized with guanidin was used as a new extraction agent to concurrently extract lead, copper, cadmium, and zinc ions. The extraction was carried out in 25ml of solution containing 2 mg/l of each ion in 10 minutes and with very small amount of sorbent (10 mg). Results of the research have been published in details in Food Chemistry, vol. 141, issue 3, December 2013, pp. 1916-1922.

Lock up the medicine chest before holiday guests arrive

BLOOMINGTON, Ind., Dec. 24 (UPI) -- The Christmas tree is trimmed, the house decorated and gifts wrapped but before guests are invited, U.S. experts suggest locking up the medicine chest.

"We don't like to think of guests rifling through our medicine chests, but it is a possibility," Courtney Stewart, research associate at the Indiana Prevention Resource Center at the Indiana University School of Public Health-Bloomington, said in a statement.

"So, play it safe. Guests will be using bathrooms and placing coats and purses in various rooms. Prescription drugs of any kind should be placed in a safe location where they are kept locked and out of the hands of guests."

The potential for misuse of prescription drugs and alcohol during the holidays increases because of social gatherings, tradition and travel, Stewart said.

The abundance of alcohol and alcohol advertising over the holidays can ramp up consumption for both social drinkers and people who might be struggling with alcohol consumption.

"Party hosts may serve stronger drinks than are usually consumed, and guests may drink many more beverages while 'under the influence of conviviality and cheer,'" said Carole Nowicke, a research associate at the IPRC. "Adults with alcohol problems and under-aged youth may find alcohol unmonitored and plentiful even in homes where alcohol typically is not available."

Stewart and Nowicke suggest:

-- Lock up or move all prescription medications to a safe location, such as a locked car or a drawer in a locked bedroom.

-- Place over-the-counter medicines in a handy yet private location where you can dispense them to guests who may need an aspirin or antacid, etc.

-- Choose non-alcoholic drinks at social events.

Prolonged Exposure Therapy Found Beneficial in Treating Adolescent Girls with PTSD

PHILADELPHIA Researchers at Penn Medicine report in the December 25 issue of JAMA that a modified form of prolonged exposure therapy in which patients revisit and recount aloud their trauma-related thoughts, feelings and situations shows greater success than supportive counseling for treating adolescent PTSD patients who have been sexually abused.

Despite a high prevalence of posttraumatic stress disorder (PTSD) in adolescents, evidence-based treatments like prolonged exposure therapy for PTSD in this population have never been established.

We hypothesized that prolonged exposure therapy could fill this gap and were eager to test its ability to provide benefit for adolescent patients, says Edna Foa, PhD, professor of Clinical Psychology in the department of Psychiatry in the Perelman School of Medicine at the University of Pennsylvania, who developed prolonged exposure therapy.

The concern has been that prolonged exposure therapy, while the most established evidence-based treatment for adults with PTSD, could exacerbate PTSD symptoms in adolescent patients who have not mastered the coping skills necessary for this type of exposure to be safely provided.

Adolescence is often a time when children begin to test limits and are in and out of situations, both good and bad situations that often determine the path their lives take into adulthood.

The six-year (2006-2012) study examined the benefit of a prolonged exposure program called prolonged exposure-A (PE-A), that was modified to meet the developmental stage of adolescents, and compared it with supportive counseling in 61 adolescent girls, ages 13-18, with sexual abuse-related PTSD. In the single-blind randomized clinical trial, 31 received prolonged exposure-A, and 30 got supportive counseling.

Each received 14 60- to- 90 minute sessions of either therapy in a community mental health setting. The counselors were familiar with supportive counseling but nave to PE-A before the study; their PE-A training consisted of a 4-day workshop followed by supervision every second week.

Outcomes were assessed before treatment, mid-treatment and after treatment and at three, six and 12-month follow up. During treatment, patients receiving PE-A demonstrated greater decline in PTSD and depression symptom severity, and improvement in overall functioning. These differences were maintained throughout the 12-month follow up period.

Another key finding of this research was that prolonged therapy can be administered in a community setting by professionals with no prior training in evidence-based treatments and can have a positive impact on this population, Foa says.

Robert Wood Johnson Medical School – Wikipedia, the free …

Rutgers - Robert Wood Johnson Medical School Motto Sol iustitiae et occidentem illustra Established 1961 Type Public Dean Peter S. Amenta, MD, PhD Academic staff 2,800 (full-time, part-time, and volunteer) Students 640 Other students 450 (residents and Fellows) Location New Brunswick, Piscataway, and Camden, New Jersey, USA Campus Urban and Suburban Affiliations Rutgers, The State University of New Jersey Website http://rwjms.rutgers.edu

Robert Wood Johnson Medical School (RWJMS) is the graduate medical school of Rutgers University. It is located in New Brunswick and Piscataway. Robert Wood Johnson is one of two medical schools that are a part of Rutgers University's School of Biomedical and Health Sciences.[1]

In cooperation with Robert Wood Johnson University Hospital, the medical school's principal affiliate, they comprise New Jersey's premier academic medical center.[citation needed] In addition, Robert Wood Johnson Medical School has 34 other hospital affiliates and ambulatory care sites throughout the region.Robert Wood Johnson Medical School encompasses 20 basic science and clinical departments, and hosts centers and institutes including The Cardiovascular Institute, the Child Health Institute of New Jersey, the Center for Advanced Biotechnology and Medicine, the Environmental and Occupational Health Sciences Institute, and the Stem Cell Institute of New Jersey.

The medical school maintains educational programs at the undergraduate, graduate, and postgraduate levels for more than 1,500 students on its campuses in New Brunswick and Piscataway, and provides continuing education courses for health care professionals and community education programs.

Previously an academic unit of the University of Medicine and Dentistry of New Jersey, Robert Wood Johnson Medical School transferred to Rutgers, The State University of New Jersey, as part of the New Jersey Medical and Health Sciences Education Restructuring Act, on July 1, 2013.

Robert Wood Johnson Medical School was formed in 1961 as Rutgers Medical School, part of Rutgers University, with a planning grant from the Kellogg Foundation. In the fall of 1963, the first faculty members joined the school and the first class of 16 students entered in September 1966. At the end of two years of instruction, students transferred to other four-year medical schools to complete their education.

In 1970, the Rutgers Medical School was organizationally united with the New Jersey Medical School in Newark and the New Jersey Dental School to form the "College of Medicine and Dentistry of New Jersey" (later renamed the University of Medicine and Dentistry of New Jersey), and became a full four year medical school. Raritan Valley Hospital, in Green Brook, New Jersey, was the school's original clinical teaching affiliate, until 1977 when Middlesex General Hospital (now Robert Wood Johnson University Hospital) in New Brunswick became the primary teaching hospital of Rutgers Medical School. The first doctor of medicine degrees were conferred in June 1974. In 1980, the Board of Trustees established a second clinical campus of the medical school in Camden with Cooper University Medical Center, (now Cooper University Hospital). On July 1, 1986, UMDNJ-Rutgers Medical School was renamed Robert Wood Johnson Medical School.

In 1995 the Clinical Academic Building (CAB), a 225,000-square-foot (20,900m2) facility for outpatient activities, research laboratories, academic offices and support programs, opened adjacent to Robert Wood Johnson University Hospital, in New Brunswick, and in 1997, the 75,000-square-foot (7,000m2) Cancer Institute of New Jersey (CINJ) opened its doors. CINJ became an independent institute on July 1, 2013 with the integration to Rutgers, but is managed by faculty of the medical school. In October 2003, the school opened and dedicated the Research Building in Piscataway, which houses twenty-seven research laboratories as well as a core imaging suite, interdepartmental instruments, and a core nuclear magnetic resonance facility.

Construction of the Child Health Institute of New Jersey was completed in 2005, linking Robert Wood Johnson Medical School, The Bristol-Myers Squibb Children's Hospital at Robert Wood Johnson University Hospital, and the PSE&G Children's Specialized Hospital, in New Brunswick. This tri-institutional biomedical research and pediatric care center serves as the cornerstone of the childrens academic campus of the medical school bringing the scientific and clinical programs together with hospital based programs. In May 2004, the State of New Jersey created the Stem Cell Institute of New Jersey.

Over the course of a decade, beginning in 2002, various state and university commissions were established to explore restructuring higher education in the stateand UMDNJ specifically. Commissions led by P. Roy Vagelos, MD; The Hon. Thomas H. Kean; and Sol J. Barer, PhD, produced a variety of recommendations during that time, until on Aug. 22, 2012, the New Jersey Medical and Health Sciences Education Restructuring Act was approved by the state legislature and signed by Governor Chris Christie.As a result of this legislation, Robert Wood Johnson Medical Schools New Brunswick campus and all schools, institutes, and centers of UMDNJexcept for the School of Osteopathic Medicine, the entire Stratford campus, the remaining UMDNJ facilities in Camden, and University Hospitalwere transferred to Rutgers, The State University of New Jersey, on July 1, 2013. In addition to Robert Wood Johnson Medical School becoming a part of Rutgers, its Cancer Institute of New Jersey became an independent institute at Rutgers University, distinct and separate from the Medical School. Robert Wood Johnson Medical Schools Camden campus was transferred to Rowan University on that date as well, joining Rowans Cooper Medical School.
