Novel Self-Powered Nanoparticles Developed to Deliver Healing Drugs Directly to Bone Cracks. 29 August 2013 — A novel method for finding and delivering healing drugs to newly formed microcracks in bones has been invented by a team of chemists and bioengineers at Penn State University and Boston University.
Doctors are now able to PRINT entire body parts such as ears and noses using 3D printing technology. Scientists are now able to use a 3D printing technique to produce biodegradable 'scaffolding' for facial features and internal organsUsing the printouts, bioengineers are able to cultivate human skin cells around the scaffolding to create living tissueThe technique has already been used on patients for small body parts such as blood vessels and it is hoped that facial features will soon be availableExperts are also hoping technique will make man made organ transplantation possible within the next two decades By Rachel Reilly Published: 11:07 GMT, 17 June 2013 | Updated: 14:21 GMT, 17 June 2013.
A Vending Machine To Give Helmets To Dangerously Under-Protected Bike Share Riders. An important first step for cities eager to encourage cyclists to reclaim the streets might be to install some bike lanes.
A second step? Implementing a city-wide bike-sharing program--as more and more cities around the world are doing--so that people can try out urban cycling before investing in their own vehicle or can bike without worrying about theft and maintenance. New teeth grown from urine - study. 29 July 2013Last updated at 19:44 ET By James Gallagher Health and science reporter, BBC News Could stem cells be a source of new teeth?
Scientists have grown rudimentary teeth out of the most unlikely of sources, human urine. The results, published in Cell Regeneration Journal, showed that urine could be used as a source of stem cells that in turn could be grown into tiny tooth-like structures. The team from China hopes the technique could be developed into a way of replacing lost teeth.
Other stem cell researchers caution that that goal faces many challenges. Teams of researchers around the world are looking for ways of growing new teeth to replace those lost with age and poor dental hygiene. Chinese Scientists Grow False Teeth From Human Urine. Over the years scientists have made false teeth from a variety of materials – from cuspids crafted out of animal bone to chompers made from wood and gold.
However a group of Chinese scientists just announced that they have successfully grown “rudimentary teeth” from an extremely unlikely and slightly unsettling source: human pee. According to the research, published in Cell Regeneration Journal, the tiny tooth-like structures were grown from stem cells harvested from urine. While the scientists believe it could herald a new, albeit disturbing, age for false teeth, stem cell researchers believe they could have several hurdles to overcome. The Chinese research team, which is based at the Guangzhou Institutes of Biomedicine and Health used urine as it contains cells that are normally passed out of the body – but in the laboratory they can be come stem cells.
These cells were then mixed with organic material to form teeth. . + Cell Regeneration Journal via BBC News Images © Wonderlane.

Carry on camping - can a week under canvas reset our body clocks? Researchers say that camping for a week can reset the biological clock that governs our sleeping patterns.
The scientists argue that modern life disrupts our sleep through exposure to electric light and reduced access to sunlight.

Rise in violence 'linked to climate change' 2 August 2013Last updated at 03:18 ET By Rebecca Morelle Science reporter, BBC World Service The researchers believe that war and personal conflicts are links to shifts in climate Shifts in climate are strongly linked to increases in violence around the world, a study suggests.
US scientists found that even small changes in temperature or rainfall correlated with a rise in assaults, rapes and murders, as well as group conflicts and war. The team says with the current projected levels of climate change, the world is likely to become a more violent place. The study is published in Science. Quantifying the Influence of Climate on Human Conflict. A rapidly growing body of research examines whether human conflict can be affected by climatic changes.
Drawing from archaeology, criminology, economics, geography, history, political science, and psychology, we assemble and analyze the 60 most rigorous quantitative studies and document, for the first time, a striking convergence of results. We find strong causal evidence linking climatic events to human conflict across a range of spatial and temporal scales and across all major regions of the world. New antibiotic that attacks MRSA found in ocean microbe. 31 July 2013Last updated at 13:40 ET By Simon Redfern Reporter, BBC News The discovery of genuinely new antibiotics is rare.
Researchers claim 3-D printers pose 'health risk' CHICAGO — Three-dimensional printers using the fused deposition molding (FDM) process could pose a health risk to operators, according to researchers from the Illinois Institute of Technology in the U.S. and the National Institute of Applied Sciences in Lyon, France. Writing in the journal Atmospheric Environment, Brent Stephens, Parham Azimi, Zeineb El Orch and Tiffanie Ramos note that “heated thermoplastic extrusion and deposition … is a process that has been shown to have significant aerosol emissions in industrial environments.
Huge viruses may open 'Pandora's' box: French study. These viruses are so big they might just be your ancestors. Two newly discovered viruses are twice as large as the previous record-holders and may represent a completely new life form, French scientists reported in the US journal Science. Bubonic plague 'could return to the UK' Climate changes and increasing globalisation could bring back the diseases of the Middle Ages, an expert has warned. Vic Simpson of the government's Veterinary Laboratories Agencies told a seminar at the British Veterinary Association's annual conference that the bacterium responsible for the Black Death which ravaged Europe and Asia between the 14th and 17th centuries could find its way back to Britain.
