#Sixteen nanometres in 3d Tomography enables the interior of a vast range of objects to be depicted in 3d from cellular structures to technical appliances.
a feat that is unmatched for X-ray tomography. The measurement is non-destructive, so it allows to study small details in the context of their surroundings
Researchers from the Paul Scherrer Institut have developed now an instrument that makes X-ray tomography possible at an unprecedented 3d resolution.
For thick samples, hard X-ray tomography was limited to a resolution of around 150 nanometres. For many years, X-ray tomography has been conducted at various synchrotron light sources, such as The swiss Light source at the PSI.
This kind of imaging involves screening the object from different directions with X-ray light in such a way that a fluoroscopic image a so-called radiograph is generated each time

#A Light-Reflecting Balloon Catheter Repairs the Heart without Surgery Harvard-affiliated researchers have designed a specialized catheter for fixing holes in the heart by using a biodegradable adhesive and patch.
The team reported in the journal Science Translational Medicine that the catheter has been used successfully in animal studies to help close holes without requiring open-heart surgery.
Their catheter device utilizes UV LIGHT technology and can be used to place the patch in a beating heart.
The catheter is inserted through a vein in the neck or groin and directed to the defect within the heart.
Once the catheter is in place, the clinician opens two positioning balloons: one around the front end of the catheter, passing through the hole,

#Can One-shot Syringes Save The World? Marc Koska has had shot a at saving the world; a single shot that has taken him 31 years.
finding out how drug addicts used syringes and traveling to immunization camps in Africa and to Geneva to learn about public health policy.
non-reusable syringe, immersed himself in the intricacies of syringe design and patents, toured syringe manufacturing plants and studied plastic injection moulding techniques.
Thirty one years later he found himself in Geneva again in February when he watched as the World Health Organisation executed only the third Global Health Initiative in its 67-year history.
Its edict that only curative health programmes using auto-disable syringes and safety needles will receive WHO funding after 2020 should radically reduce infections caused by dirty syringes.
Dr Selma Khamassi, head of THE WHO team for injection safe, told BBC News that the new policy will hopefully help eliminate the 1. 7million new Hepatitis b cases
Koska invention in 1996 of the K1 auto-disable syringe has led the way. The syringes of his Star company are made of the same materials as conventional syringes,
manufactured on tooling and assembly equipment that already existed and used in exactly the same way as traditional syringes. t looks
and behaves exactly like a normal syringe, he says. t uses 95 per cent of the same manufacturing equipment that makes a traditional syringe
and when using it you do everything you would do with a normal syringe. But if you try to reuse it after that,
it locks and then snaps and breaks in half. We have sold nearly five billion of these
and we have heard never of an instance of them being reused. Koska innovation was to insert a mechanical valve in the plunger.
That sounds simple enough but what he had anticipated not was the difficulty he would have trying to change the business model of syringe manufacture. ifty billion traditional syringes are made around the world every year
Indeed, the price differential between conventional and auto-disable syringes has been a major barrier to getting the world to convert to safe syringes without the big stick of a global regulator.
Standard syringes cost between two and four cents each while mart syringestypically come in at between four and six cents.
who was involved heavily in drawing up its new syringe policy. he world needed guidance, he says. t just needed to unite under something sensible.
Koska is trusted by the US Senate to advise on syringe policy and had a personal audience in Davos this year with most of the leaders in the developing world to get them to commit to adopting his syringe practice.
Britain Queen Elizabeth has awarded also him the Order of The british Empire for service to global health. have been able to pull the manufacturers together,
THE WHO edict states that the organisation wants to convert every syringe in the world to auto-disable by 2020.
The battleground is in the curative market the use of syringes to treat existing health conditions,
which accounts for 95 per cent of the world syringes. The remaining 5 per cent the use of syringes to vaccinate against potential disease converted en masse to auto-disable syringes in 1999.
Koska is realistic expecting the quickest conversions to come in nations that are supported by international donors. t would be ridiculous to give a country $50m to help them with health
if they were reusing syringes because it would not be helping. he says. Conversion costs manufacturers nly a couple of million dollars, according to Koska an expense that is set to become the effective cost of staying in the syringe manufacturing business.
To prove the point, he invited 45 syringe manufacturers to Geneva to see the edict become official. ow they have got it from the horse mouth,
says Koska. hey will have to convert within the coming years. Koska is evangelising from a position of strength.
While a handful of other producers have invented their own auto-disable syringe, Star K1 syringes are manufactured under licence by 13 companies around the world, giving them a substantial lead. here no other product in this space that
I know of that is in more than one factory, says Koska. e have dominated completely in the preventative market because of our easy conversion process.
