Dna nanorobot specifically attacks cancer cells

DNA nanorobot specifically attacks cancer cells

The miniature machine, modeled on the body’s own immune system, consists of cleverly folded genetic material (DNA) and can in principle be tailored to any target cell in the organism, as the developers led by shawn douglas of harvard university in boston report in the u.S. Journal "science".

So far, however, the robot has only been tested in cell cultures. Whether it can ever be used on humans has not yet been clarified. Similar approaches are also being pursued by other research groups.

The nanorobot resembles a hexagonal cage that is only 45 nanometers (millionths of a millimeter) high and 35 nanometers thick – making it about 2000 times thinner than a human hair. The cage, folded using a special technique called DNA-origami, consists of two halves held together by custom-made bars. These bars are designed in such a way that, like white blood cells, they can recognize the surface of desired target cells – such as cancer cells – and dock onto them. With docking, the latch reconfigures itself so that the nanocage swings open.

New technology for kissinger water

New technology for kissinger water

Since the 19. Bad kissingen healing water is bottled in the kurhausstrasse in the twentieth century. The spa tenants at the time, the brothers peter and ferdinand bolzano, had water from the rakoczy and pandur springs filled into clay vessels around 1830. They shipped the water both within europe and around the world, thus also contributing to bad kissingen’s reputation as a world spa.

Those glory days were a long time ago. Until 2001, the state baths administration still bottled medicinal and bitter water on a large scale and delivered it throughout germany, but this was then discontinued due to insufficient demand. Since then, staatsbad gmbh has only bottled smaller quantities every three years in order to have reserves, to sell the water as a souvenir and, above all, to obtain the approvals required for bottling under pharmaceutical law. Recently, however, this was also threatened: the filling line in the jug magazine broke down. A good year ago, the bavarian center for state baths invited tenders for the repair work. In the meantime, it has been completely renewed. The costs of around 228.000 euro is borne by the freestate.

Repair no longer makes sense

The 30-year-old system could no longer be repaired. "Due to its age, the existing treatment and filling plant for medicinal water was completely worn out. A repair was neither economically justifiable nor technically sensible", A spokeswoman for the bavarian ministry of finance informed us on request. The old plant was therefore replaced by a new one. After the general renovation of the kurhausbad, it will move there. It is used there for show bottling staged for tourists.

State government welcomes hisense plans to acquire loewe

The bavarian state government supports the plans of the chinese technology group hisense to take over the insolvent TV producer loewe in kronach. This is the result of a meeting of leading hisense representatives, representatives of the state government and representatives of the region on thursday evening in munich, which was initiated by hans michelbach, a member of the bundestag from coburg-kronach.

"With hisense, loewe would not only get a financially, but also technologically potent new owner and the region a new impulse", michelbach said after the meeting. "Everything now depends on the right course being set at the next creditors’ meeting."

According to a press release from michelbach’s office, hisense vice president lan lin, who traveled from the company’s headquarters in qingdao especially for the meeting, explained that in the event of a takeover, his company wanted to preserve loewe as a traditional german company and market its premium products around the world. Production and delivery capability of loewe could be resumed within three months after a takeover. Around 100 employees are to be hired for this purpose.

Conti depresses debt mountain after record profit

Conti depresses debt mountain after record profit

However, conti is hoping that passenger car production and also the tire business will pick up again, especially in the second half of the year. There were various best figures in 2012: for example, the bottom line is a profit of 1.9 billion euros. The debt burden fell noticeably and far more than planned.

Conti’s coffers are fuller than they were a year ago: at the end of the year, the company had 2.4 billion euros in cash and cash equivalents, a good 50 percent more than at the end of the previous year. Degenhart said acquisitions of suitable companies with annual sales of up to one billion euros are "conceivable". He did not provide further details on regions, for example.

The stock market rewarded the figures with an interim gain of around 4 percent. Conti shares were among the top performers on the dax throughout the day.

Naturstrom is flying high with wind turbines

Naturstrom is flying high with wind turbines

Word has spread that electricity doesn’t just come out of the socket. However, it is still far too little known that he "naturally" also comes from the region: from naturstrom – one of the leading providers of renewable energies, which has one of its mainstays in forchheim.

"Am 16. April 1998, naturstrom AG was founded – by 16 committed people who were all active in environmental associations.", tells dr. Thomas E.Banning, who has been at the helm of the company since 2002. And since his former job for siemens brought him to heroldsbach, naturstrom’s division responsible for self-generated electricity is located in forchheim. In an office wing of the former blank building in nurnberger strabe, 35 employees are involved in everything that has to do with the creation of regenerative plants."We are active in all areas of renewable energies", explains thomas banning: photovoltaic technology (solar energy), biomass, wind and hydropower.
He notes, however, that the focus has shifted considerably: wind power, for example, which years ago was considered economically and technically unfeasible in the local region, is now also an issue in franconia.

Finding sensible locations

that the energy turnaround is heating up the minds and changing the landscape, this is also clear to the naturstrom manager. "With every plant there is always an impact on nature", says banning bluntly. But there is a balancing of interests: "how much secure energy supply do we want, and where do we need it??" it doesn’t make sense to put wind turbines next to the basilica in gobweinstein," explains banning. But this could certainly be done on the A73 near scheblitz, for example, where the wind is strong and the population low. In addition, an encroachment on the landscape next to a highway that already exists is bearable. For banning, the middle ground between nature conservation and secure energy supply is: "you have to do one without demonizing the other.
Naturstrom’s idea is eco-logical: "we don’t want to put as much as possible somewhere in order to maximize profits", emphasizes banning "but we want to find solutions in consultation with the local people that are capable of reaching a consensus.". It is a matter of finding sensible locations, he said. "We are not aiming for maximum performance, but rather a path to sensible energy generation" . That’s why naturstrom founds operating companies for wind farms. At the end of 2011, the first wind farm in the bamberg district to be built entirely by naturstrom was put into operation. Citizens can participate not only through profit participation rights (from 1000 euros), but also as co-partners.

Total regional

the idea behind such energy cooperatives: on the one hand, value creation is expanded in the region, on the other hand, investors from the region are attracted, and finally, energy supply is created for the region. Thilo jungkunz tries to win over local communities and associations for this idea in information events.
Natural power is on the upswing. "15 years and not a bit quiet, thomas banning’s anniversary headline in his naturstrom magazine. In the meantime, a sales volume of around 200 million euros has been achieved. In terms of electricity, that is 940 00 gigawatt hours supplied. Thomas banning impressively explains what this means: "you could supply forchheim with this for about eight years.
