The votes are in with NASA announcing the winner of its Z-2 spacesuit design challenge. For the challenge, the public was invited to choose one of three alternative designs for a new prototype spacesuit with the Technology option winning with 233,431 votes, or about 63 percent of the total vote. The Technology design will now be used in the completed Z-2 suit as part of NASAs project to create a new spacesuit for the exploration of Mars.
The Z-2 is that latest in the Z-series of spacesuit prototypes created for NASAs Advanced Exploration Systems Division. The goal is to develop a new suit, through a number of iterations, that can be used for a manned mission to Mars. The Z-2 is not itself a flightworthy suit and will not be sent into space because it lacks the specific high-performance materials and design details needed for working outside the Earths atmosphere.
The challenge allowed the public to vote for one of three versions of the Z-2 cover layer, each of which was designed by Philadelphia University and the primary suit vendor, ILC Dover. Each of these designs highlighted a mobility characteristic, as well as including electroluminescent wiring, which has never been used on a spacesuit before. NASA hopes that the wiring will help in space crew identification.

The cover layer is the outermost layer of a spacesuit that protects the lower layers and spacesuit components from snagging and abrasion. In a fully operational spacesuit, the layer also protects the astronaut against micrometeorites, heat, cold, and radiation. NASA also admits that it makes the suit look better.
According to NASA, the Z-2 has a number of improvements over the earlier Z-1, which has been the subject of two years of evaluations. The Z-2 has a hard composite upper torso for greater durability, the shoulder and hip joints are more mobile, and the boots are more like those that would be found on a space-ready suit. In addition, the Z-2 can withstand a full-vacuum during testing.
The winning Technology design, as the name implies, harkens back to more conventional spacesuits, but with some sci-fi elements added, such as Luminex wire and light-emitting patches for crew identification. It also has exposed rotating bearings, collapsing pleats for mobility and highlighted movement, and abrasion-resistant panels on the lower torso.
NASA says that the Z-2 will be completed by November and will be tested at NASA's Johnson Space Center in Houston in the Neutral Buoyancy Lab, which simulates weightless conditions using a swimming pool, then on a simulated Martian surface. The engineers will evaluate the Z-2s mobility, comfort and performance, as well as subjecting it to multiple vacuum chamber tests with pressures down to that of a full vacuum. The results of the tests will then be used in designing the Z-3.

New nanotechnology could provide an effective replacement to best-by dates by gauging ambient temperature and accurately indicating when food has gone bad
A research team led by Chao Zhang of Peking University in Beijing, China has developed a color-coded smart tag that employs nanotechnology to indicate when packaged food is in danger of spoiling or already spoiled. The kind of technology would serve as an effective supplement or replacement to the current method of sell-by dates. While the sell-by date provides the consumer with some useful information, they operate on a good deal of guesswork. Although the guesses are highly informed and accurate in ideal storage conditions, if the storage conditions are worse than the determiners of the sell-by date intended, the system is thrown off. The smart tags are intended to address this since they are designed to react to the actual storage conditions rather than how the product might or should have been stored.
How Real Time Monitoring Can Improve Food Safety
Zhang states, A real advantage is that when manufacturers, grocery store owners, and consumers do not know if the food has been unduly exposed to higher temperatures which could cause unexpected spoilage the tag still gives a reliable indication of the quality of the product.
The tags are gel-like in texture, about the size of a corn kernel, safe, and even edible. They function by reacting to the ambient temperatures around them and change color to indicate when the product has become spoiled. Red indicates 100 percent fresh; green indicates 100 percent spoiled, and orange and yellow indicate the foods quality is beginning to deteriorate. The research lab uses gold nanorods that are red, which is why red is used for fresh instead of green. In the tag there is also silver chloride and vitamin C which interact with the nanorods over time. The nanorods become coated in silver and have their composition and shape changed, thereby altering their color. The tags can be programmed to mimic all ambient temperatures and display when the food has gone bad, regardless of what a sell-by date may indicate.
Since temperature is a variable in the way the tags function, the tags change color at different rates depending on how they have been stored. The current version of the tags was developed using E. coli bacteria in milk at various temperatures as a reference model. Zhang comments that similar models could easily be created for other products. The tags are also incredibly inexpensive to produce. Despite using precious metals in their manufacturing, each tag only costs about $0.002 to produce. Zhang says that the process has been patented in China and the next step is finding a manufacturer to make production more practical.

Will Food Spoilage Smart Tags Render Best-By Dates Obsolete?
London, United Kingdom (PRWEB UK) 1 May 2014
Pro Bono Bio (PBB), the world leader in nano-physical medical devices, is proud to announce that it has been appointed as an official supplier to top English premiership rugby club, Saracens, for their breakthrough joint-care product, FLEXISEQ.
This announcement is the culmination of nearly 6 months of collaboration between PBB and the Saracens medical staff who have been trialling FLEXISEQ among players of their elite squad, since the product hit the UK market in early December 2013.
FLEXISEQ, an injection-free biolubricant for joints, is a revolutionary new wellness product for the maintenance of joints that are either compromised by arthritic symptoms or those that are at higher risk of suffering wear and tear. The topically applied product delivers joint lubrication replacement therapy which coats cartilage surfaces to minimise friction and wear.
Saracens' Joe Collins, Head of Medical, said This is a fantastic product and one the medical team are proud and happy to have associated with the Club.
One of the players who has benefited from FLEXISEQ is Saracens, England and British & Irish Lions centre, Brad Barritt, FLEXISEQ has been a great product for me to use and has enabled me to train and compete at my best. FLEXISEQ offers me peace of mind in that it is drug-free and by lubricating my joints it protects them, shortens my recovery time and hopefully will prolong my career.
John Mayo, CEO of PBB said, As we have already proved in the arthritis field, FLEXISEQ is a game-changer and we expect the same outcome having entered the sports medicine and wellness sectors. Elite, high impact rugby is the ultimate sports test for joints. We are proud to have successfully proven FLEXISEQ in this testing environment with the Saracens medical team and wish each player and the Saracens team continued success.
FLEXISEQ fits extremely well into the field of sports medicine where healthcare professionals are overloaded with joint injuries and are ever-vigilant for safer, drug-free ways to treat them. The physicality of rugby puts extraordinary stress and strain on players bodies and injuries are inevitable. These injuries can involve joint damage which can predispose a player to the early onset of further joint problems such as osteoarthritis. FLEXISEQ provides joint lubrication replacement therapy to those joints where their natural wear and tear-reducing properties may be compromised. The product is being used by Saracens as a drug-free solution to joint pain and stiffness as well as an additional step in players rehabilitation and after-care. Replacing painkillers (such as commonly used non-steroidal anti-inflammatory drugs) saves sportsmen and women from the well documented risks of side effects and slowing of the natural recovery and rehabilitation that can be caused by these painkillers.
More information is available for sport healthcare professionals upon email request to wellness(at)flexiseq(dot)com.

Newswise FAYETTEVILLE, Ark. Imagine a physician, sitting in a stadium press box, equipped with technology that makes it possible to continuously monitor each players physiological signs that indicate concussion.
Engineering researchers at the University of Arkansas have developed a wireless health-monitoring system that does exactly that. The system includes a dry, textile-based nanosensor and accompanying network that detects early signs of traumatic brain injury by continuously monitoring various brain and neural functions.
Wearable nanosensor systems can detect the severity of head injury by quantifying force of impact, be it light or violent, said Vijay Varadan, Distinguished Professor of electrical engineering. In real time, our system continuously monitors neural activity and recognizes the signs and symptoms of traumatic brain injury, such as drowsiness, dizziness, fatigue, sensitivity to light and anxiety.
The system is a network of flexible sensors woven or printed into a skullcap worn under a helmet. The sensors are built with carbon nanotubes and two- and three-dimensional, textile nanostructures grown at the University of Arkansas. The system uses Zigbee/Bluetooth wireless telemetry to transmit data from the sensors to a receiver, which then transmits the data via a wireless network to a remote server or monitor, such as a computer or a smartphone. A more powerful wide-area wireless network would allow the system to detect large quantities of data taken continuously from each player on the field and transmit the data to multiple locations a press box, ambulance and hospital, for example.
The sensors have considerable power and capability to monitor sensitive neural and physiological activity, Varadan said. Under stress due to impact, the sensor chips are sturdier than printed circuit-board chips and can withstand high temperatures and moisture.
The system includes a pressure-sensitive textile sensor embedded underneath the helmets outer shell. This sensor measures intensity, direction and location of impact force. The other sensors work as an integrated network within the skullcap. These include a printable and flexible gyroscope that measures rotational motion of the head and body balance and a printable and flexible 3-D accelerometer that measures lateral head motion and body balance.
The cap also includes a collection of textile-based, dry sensors that measure electrical activity in the brain, including signs that indicate the onset of mild traumatic brain injury. These sensors detect loss of consciousness, drowsiness, dizziness, fatigue, anxiety and sensitivity to light. Finally, the skullcap includes a sensor to detect pulse rate and blood oxygen level.

YouTube is offering channel producers on its site the chance to add a short intro clip to all their videos in a move geared toward improving channel branding.
Everyone knows the power of a good introduction, YouTube software engineer John Gregg said in a post introducing the new feature. Imagine watching The Simpsons without its iconic opening sequence. Wouldnt be the same, would it?
The move came in response to increasing demand from producers looking for extra ways to build a consistent brand for audiences, Gregg said.
The intro-video feature allows a channel owner to perform a one-time upload of a clip of up to three seconds whichll automatically play before every video on that channel.
Gregg outlined the simple steps youll need to take:
1 Upload the three-second intro video youd like to use to your channel as an unlisted video.
2 On your channels InVideo Programming page, click Add a channel branding intro and select the intro from a list of eligible videos.
3. Select which videos you want the intro to appear on. You can choose whether to add it to all of your videos, or just the ones youve uploaded after a certain date. You can always remove or change the intro later.
Simple, huh?
Channel owners should keep in mind that the intros are not allowed to be used as ads, sponsorships, or product placements, nor be used with a video which itself is an ad.

On Friday 2 May, 2014, The Lancet and The Lancet Respiratory Medicine will release three new review articles and an Editorial on asthma, ahead of World Asthma Day on May 6 and the American Thoracic Society's international conference (ATS 2014) in San Diego (May 16-21).
The Lancet: Outdoor air pollution and asthma
Traffic and power generation are the main sources of urban air pollution. The idea that outdoor air pollution can cause exacerbations of pre-existing asthma is supported by an evidence base that has been accumulating for several decades, with several studies suggesting a contribution to new-onset asthma as well. In this review, Professors Michael Guarnieri and John R Balmes, of the University of California, San Francisco, USA, discuss the effects of particulate matter (PM), gaseous pollutants (ozone, nitrogen dioxide, and sulphur dioxide), and mixed traffic-related air pollution on asthma. Reviewing evidence from the past five years, they suggest that air pollutants probably cause oxidative injury to the airways, leading to inflammation, remodelling, and increased risk of sensitisation. Although several pollutants have been linked to new-onset asthma, the strength of the evidence is variable. The authors also discuss clinical implications, policy issues, and research gaps relevant to air pollution and asthma.
The Lancet Respiratory Medicine: Asthma genetics and personalised medicine
In this review, Professor Stephen Holgate and colleagues at the Faculty of Medicine, University of Southampton, UK, and collaborators in the US, discuss genetic approaches to asthma, which have identified novel genetic targets in the pathogenesis of the disease, although so far these targets account for only a small proportion of the heritability of asthma. Recognition of the importance of disease heterogeneity, the need for improved disease phenotyping, and the fact that genes involved in the inception of asthma are likely to be different from those involved in severity, widens the scope of asthma genetics. The identification of genes implicated in several causal pathways suggests that genetic scores which capture multiple gene effects could be used to capture the individual influence of genes on the expression and treatment opportunities for this disease in individuals. Geneenvironment interaction adds another layer of complexity, which is being successfully explored by epigenetic approaches that assess how the human genome is accessed. Pharmacogenetics is one example of how geneenvironment interactions are already being taken into account in the identification of drug responders and non-responders, and patients most susceptible to adverse effects. Such applications represent one component of personalised medicine, an approach that places the individual at the centre of health care.
The Lancet: Diagnosis, management, and prognosis of preschool wheeze
Preschool children (ie, those aged 5 years or younger) with wheeze consume a disproportionately high amount of health-care resources compared with older children and adults with wheeze or asthma, representing a diagnostic challenge, according to this Review by Professor Francine Ducharme, of CHU Sainte-Justine, Cte Sainte-Catherine, Canada, and colleagues. Several risk factors related to genetic, prenatal, and postnatal environment are associated with preschool wheezing, and findings from several studies have shown that preschool children with wheeze have deficits in lung function at six years of age that persisted until early and middle adulthood, suggesting increased susceptibility in the first years of life that might lead to persistent sequelae. Interventions to modify the short-term and long-term outcomes of preschool wheeze should be a research priority, say the authors.

MARTINEZ -- The Antioch school district will have to halt its effort to establish Dozier-Libbey Medical High School as a district-run charter school, a Contra Costa Superior Court judge ruled Thursday.
Judge Laurel Brady affirmed a tentative ruling granting a temporary restraining order request by teachers at the school trying to stop the district's move.
The teachers, hoping to convert Dozier-Libbey into an independent charter school free of district control, were elated upon hearing the news Thursday afternoon. The injunction is aimed at "maintaining the status quo until a final determination on the competing petitions is had," Brady said.

"This is exactly the news we were hoping for, an opportunity to take the legal route and show the merits of our petition," said Stacey Wickware, one of the lead petitioners.
Superintendent Donald Gill said Thursday afternoon he hadn't had a chance to look at the decision yet, and that district officials plan to talk with their attorneys about the next steps.
"This is just one step along the journey. There are a lot of steps yet to take," Gill said.
Last month, Antioch Unified filed its own charter petition for the medical-themed magnet school to thwart the teacher-led petition -- a novel move for California that has raised questions and concerns among those who follow charter school-related efforts.
Several times in her ruling, Brady noted the uniqueness of the situation and scant case law to assess the circumstances.
During a court hearing Monday, Antioch Unified argued that it had established a startup charter school and that it must move forward quickly to start school in August. But Brady noted in her ruling the school had a similar name, same location and state code number, and was assigned the same state test scores as the existing school.
