Blood rushes to the site of the injury and within minutes the flow stops as a plug forms at the site.
The tissue beneath and around the plug works to knit itself back together and eventually the plug disappears.

#What exactly is Google's'cancer nanodetector'?'Last week US tech giants Google made a splash in the media announcing plans to develop new'disease-detecting magnetic nanoparticles'.
'This was welcomed almost universally after all trying to detect diseases earlier is something that's a focus of many research organisations including ours.
what Google are actually planning apart from getting a lot of coverage in the media he says.
But then they're Google he says. They do things differently. The way traditional science works is to map out all the possible risks demonstrate you've accounted for them
Google are doing the opposite they're saying'we want to get to here we'll worry about the details later'.
Google have been similarly vague about the precise form of nanotechnology they aim to use Graham points out:
This isn't all about Google says Graham. It's worth pointing out that Google are far from being the only show in town.
There are loads of different research groups looking into what is called collectively'biosensing'continuous monitoring of
it seems according to this article in Wired that Gambhir originally advised Google about nanotechnology. What are the current challenges facing nanodetectors?
So for Google's biomonitor they need to work out how to keep the particles in the body
This is something Google really seem to have ducked in their announcement. We don't need to dwell on it too much
but there's been a lot in the press in the last year about who has access to Google's data and under
what circumstances says Graham referring to reports of Government agencies accessing user data from tech companies like Google and Facebook.
Professor Graham's'take-home'message is that it's a mistake to see Google as the only organisation focusing on nanotechnology to detect disease it's a vibrant active field with incredible potential but still in its early days.

So far in vivo testing in mice has shown that this approach produces significant accumulation of drugs in tumor sites instead of healthy organs.
Current panels can process only 20 percent of the solar energy they take in. By applying the nanowires the surface area of the panels would increase
and allow more efficient solar energy capture and conversion. The wires could also be applied in the biomedical field to maximize heat production in hyperthermia treatment of cancer.
In fuel cells these nanowire arrays can be used to lower production expenses by relying on more cost-efficient catalysts.
or outperform the current use of platinum and show that these nanowire arrays are better catalysts for the oxygen reduction reactions in the cells says Dr. Manashi Nath assistant professor of chemistry at Missouri S&t.

#Breakthrough in molecular electronics paves the way for DNA-based computer circuits in the future In a paper published today in Nature Nanotechnology,
The central technological revolution of the 20th century was the development of computers, leading to the communication and Internet era.
A computer with the memory of the average laptop today was the size of a tennis court in the 1970s.
Yet while scientists made great strides in reducing of the size of individual computer components through microelectronics,
they have been less successful at reducing the distance between transistors, the main element of our computers.
and extremely expensive to miniaturize an obstacle that limits the future development of computers. Molecular electronics, which uses molecules as building blocks for the fabrication of electronic components,
which could in turn be used in computers, are DNA molecules. Nevertheless, so far no one has been able to demonstrate reliably and quantitatively the flow of electrical current through long DNA molecules.
which could lead to a new generation of computer circuits that can be sophisticated more, cheaper and simpler to make. k
the new mobile device would likely cost ten times less, around $10, 000.0

#New research points to graphene as a flexible low-cost touchscreen solution New research published today in the journal Advanced Functional Materials suggests that graphene-treated nanowires could soon replace current touchscreen technology
The majority of today's touchscreen devices such as tablets and smartphones are made using indium tin oxide (ITO)
Researchers from the University of Surrey and AMBER the materials science centre based at Trinity college Dublin have demonstrated now how graphene-treated nanowires can be used to produce flexible touchscreens at a fraction of the current cost.
Using a simple scalable and inexpensive method the researchers produced hybrid electrodes the building blocks of touchscreen technology from silver nanowires and graphene.
and bendable smart displays poses a challenge to manufacturers. They want to offer consumers flexible touchscreen technology but at an affordable and realistic price.
At the moment this market is limited severely in the materials to hand which are both very expensive to make
Lead author Dr Izabela Jurewicz from the University of Surrey commented Our work has cut the amount of expensive nanowires required to build such touchscreens by more than fifty times as well as simplifying the production process.
Co-author Professor Jonathan Coleman AMBER added This is a real alternative to ITO displays and could replace existing touchscreen technologies in electronic devices.
Even though this material is cheaper and easier to produce it does not compromise on performance.
