On 25 February, the Swedish Chemicals Agency (KemI) has released a new report entitled “A safe use of nanomaterials – need for regulation and other measures.” This report responds to the request of the Government to consider the need for measures to support the development of nanomaterials. New regulations, for example, could allow an optimum consideration of risks to health and the environment.
These new materials are found today in a wide range of consumer products and in industrial products. Their number is very likely continue to increase. Knowledge about the potential impact of nanomaterials on humans and the environment are still incomplete.

The cries of the orang-utan male does not serve to indicate its identity to its peers. They also conveys information about the context in which they were issued. Females, in particular, would adjust their response accordingly.
The orang-utans have a rich repertoire of sounds – vocal or not – to communicate. Offerings include long cries are the preserve of males sexually mature. Preceded by rumbling and gurgling concluded by these series of powerful vocalizations agree to more than a mile away. By analyzing the acoustic characteristics of cries in three orang-utans of Borneo, Brigitte Spillmann and his colleagues at the University of Zurich have shown that the temporal structure and frequency varies slightly depending on the context in which these cries are issued. Females receive this modulation, and adjust their response accordingly.
We already knew that each orang-utan has his own way to make those long screams, which allows peers to identify it.

Technology Agency of the Czech Republic to consolidate domestic support for applied research and development, today launched a program that over the next six years, distributed to promote the technological development of 7.5 billion crowns for the approximately 750 projects.
Program for technological development called Alpha is divided into three parts, reflecting the partnership with the Ministries of Industry and Trade, transport and the environment. They are 1st progressive technologies, materials and systems, 2 energy resources and protecting the environment and creating a 3 sustainable transport development.
Applications should be submitted before the end of May. The first money should doputovat to successful applicants in the next year. Condition is that the level of support for the project shall not exceed 80 percent, the rest must be supplied non-public sphere, said Klusacek. Counts but the fact that the average level of grant aid will be around 65 percent. In the first year would be in the program to utilize Alfa 817 million crowns.

A recent research provides new light on one of the most important events in Earth’s history, the conquest of land by plants 480 million years ago.
No possible settler from the aquatic environment may have survive on land without the ability to cope with the dehydration, a serious threat to the organisms used to be washed by the waters.
Some clues to how the first land plants were able to avoid desiccation could be provided by the bryophytes, a group that including mosses, many of which retain a tolerance extraordinary drought. Some mosses can become so dry that crumble in your hand, but if they are wet again, begin to produce proteins in minutes.
The new research team Ralph Quatrano, University Washington at St. Louis, shows several components of the pathway signaling underlying the near-miraculous ability of moss to withstand the extreme dryness.
Interestingly, the flowering plants have not completely lost ability to tolerate desiccation: This tolerance has been limited their seeds, which dry up during the winter and yet charge life in the spring.

Researchers at the University of Manchester have shown how the nutrients in the environment are vital for healthy cell gene mutation carriers from disease.
According to scientists, diet and lifestyle can play a more important role than previously thought in a person’s ability to respond favorably to certain drugs, including some cancer treatments.
For the first time, the results provide a scientific explanation for why some people may respond to certain medications better than others, and open doors for a more individualized drug treatment for the future.
The team used baker’s yeast (a model organism studied by biologists to reveal molecular processes in higher organisms) to study the relationship between environment and genetic background.

A safety analysis performed by the Company’s security facilities and nuclear reactors (GRS) concludes that the transport of radioactive waste to the site of final disposal of Konrad [1] do not cause danger to the public, staff transport or the environment. The “transport study Konrad 2009″ confirms the assessments conducted in 1991 by GRS at the request of the Federal Ministry of Environment (BMU) and the Federal Office for Radiation Protection and Nuclear Safety (BfS).
The mine Konrad is the first site of permanent storage permitted since the Law on the exit of nuclear (Atomgesetz) [2]; waste low and medium radioactivity (FMA) must be stored.

The Research Group Engineering (GIIC) from the Polytechnic University of Valencia has presented the Speed Kidney (SK), a new device that presents itself as an alternative to the traditional speed bumps, also called projections or sleeping guard, which prevents both their discomforts as the mechanical wear on vehicles. Their advantages also helps reduce noise in the environment.
The device consists of a protrusion per lane with a kidney-shaped in plan and elevation form bulky with low-rise, located longitudinally, so that the driver only needs to follow a zigzag path, very soft and leave it between the wheels.

The research work carried out for two years by a Spin off University of Zaragoza (UNIZAR) has created a new device platform for creating wireless sensor networks. The applications of these networks are huge, which allow monitoring of parameters in places never before possible.
A good example is the detection of forest fires in order to be placed in the treetops with CO and CO2 sensors or accurately record the noise level in every street of a city.

Good news for climate protection: the EU, emissions of greenhouse gas emissions have declined for the third consecutive year, most recently from 2006 to 2007 of 1.2%, about 60 million tonnes of CO2. Save CO2 is not that difficult, as evidenced by the following examples. Did you know …

A team from the Institute of Bioengineering and Nanotechnology (IBN) has developed a method that respects the environment for the low-cost synthesis of several varieties of nanoparticles.
Researchers at the Institute of Singapore have developed a protocol for transfer of metal ions from aqueous solution into an organic solution such as toluene by mixing a solution of metal salts dissolved in water with a solution of dodecylamine (DDA ).
