Cancer threatens the conservation of some wild species because it represents one of the top causes of death. This was also recently featured on the Discovery Channel. Cancer affects some animals with the same effect as in human beings, and could be the cause of extinction of some wild species. The researchers say the Society of Preservation of Fauna and Flora of New York have found an increase in cancer cases in wild animals in recent years. According to their findings, published in Nature Reviews Cancer, the species most affected are those at risk of extinction, like the Tasmanian devil, a small marsupial carnivore, already decimated in the late nineties by a rare form of transmissible cancer (the devil facial tumor). The cause is unknown, but it has been shown that malignant cells are able to spread among the samples and through bites during fights. To save the species, biologists are now isolating infected animals in zoos or reserves. Denise McAloose and Alisa Newton, authors of the study, have investigated the possible causes of cancer in different species, and have found a correlation between cancer and pollution. For example, for the living beluga in the estuary of the St. Lawrence River (Canada), a form of bowel cancer is the second leading cause of death. The culprit could be an organic compound (a polycyclic aromatic hydrocarbon that is found in oil, but also in municipal waste), already known to be carcinogenic for our species.

The use of an organic material has been put in place a structure capable of transmitting data at rates eight times higher than those of traditional devices . The study of materials capable of transmitting data at ever higher speeds is the constant challenge of the technology of optical communications. The use of a new organic material, tested by a team of U.S. and European research coordinated by Ivan Biaggi of Lehigh University (United States), has enabled to achieve data transfers much higher than that obtained so far with traditional devices. The novelty lies in the combination of structures in silicon with organic material, identified by the initials Ddmebt . This is essentially a kind of "nonlinear" device, able to change its molecular structure to the passage of light, making it propagate at high speed. To minimize interference with the passage of data, researchers have vaporized the organic material and the deposit left on the rails of silicon and in the spaces between them. In this way, explain the authors, the molecules are deposited "like snowflakes", forming a highly homogeneous plastic. It is precisely in the interstices between the rails of silicon, filled with new material, that the light passes at high speed, allowing you to transmit data up to 170 Gigabit per second (with the traditional structures, which consist only of silicon, you can reach a maximum speed around 20-30 Gigabit per second). Combining silicon with an architecture was needed to channel and confine the flow of light within very small spaces (the guide of silicon is separated by a few tens of nanometers).

For the first time a gene was identified that allows the repair of damaged nerves in nematodes. The study is from Science Express. A gene that can stimulate the growth of nerve cells was first identified by researchers at the University of Utah (USA), thanks to cutting-edge experimental techniques and a huge genetic screening on a nematode (cylindrical or worm). The neurons, which in the embrio are able to regenerate, in adults have their capacity to "repair" reduced or absent. In other words, damage to the central nervous system (brain or spinal cord) and its consequences - paralysis, loss or reduction of cognitive faculties - are permanent. "In the past molecules have been identified that can inhibit the growth of neurons in different organisms," says the coordinator of research Michael Bastiani, "but their removal in the laboratory had no effect. That is why we went to look for those genes that can stimulate rather than inhibit, the regeneration of nerve. " Taking as a experimental model flat worms (Caenorhabditis elegans), biologists have searched for the genes that trigger the regrowth of motor (neurons that "command" voluntary muscles): in practice, with an experimental technique called RNA interference to "shut down ", one by one, 5000 on 20,000 genes in the DNA of worms (genes similar are also present in humans). The analysis led to the identification of dlk-1, which appears to play a key role in the regeneration of nerve tissue, and three other genes responsible for the formation of axons (parts of the neuron that conduct electrical signal). The researchers found that in nematodes, the gene dlk-1 not only triggers a chain of events known as "Map kinase" behind the growth of neurons, but also that their regeneration can be increased or decreased by stimulating the gene to produce amounts more or less high of the protein dlk-1.

A study explains how a yeast cell becomes cancerous: the fault is a chromosomal translocation An altering of the genome that causes cancer was finally detected and reproduced in the laboratory. The discovery, crucial for understanding the genesis and development of malignancies, is due to the geneticist Charles V. Bruschi, head of the Laboratory of Molecular Genetics of yeast, International Centre for Genetic Engineering and Biotechnology in Trieste (Icgeb) and coordinator of the Society of Italian scientific yeast (Zymi). Together with his group, Bruschi has uncovered, that the so-called chromosomal translocation is at fault. The yeast cells, whose DNA was sequenced completely in 1996, are a good model because they possess many similarities with mammalian cells and are easily manipulated by genetic engineering. Thanks to technical Bit (Bridge-Induced Translocation), designed by Bruschi and Valentina Tosato in 2005, it was possible to artificially induce the translocation and demonstrate the crucial role of this phenomenon in the formation of cancer. "Although it has long been a correlation between the presence of chromosomal translocations and the appearance of cancer cells," explains Bruschi, "so far it was not clear whether a translocation was the origin of cancer or whether, instead, it was a consequence. This is because we see patients when the cancer has already formed and in the cells already exists a particular translocation. In practice, these observations are made when it is too late to establish a relationship of cause and effect. "

A new advanced thermometer, based on noise Johnson, increased by five times the accuracy of current systems After seven years of work, researchers from the National Institute of Standards and Technology (Nist), the U.S. organization for the development of technologies, have managed to build a new type of thermometer, Johnson Noise Thermometer (Jnt), defined by the same scientists a goal of thermometry, which advances to five times the current state of the art. The new device will in fact take measurements of extreme precision, never obtained so far, fundamental for basic research and for the definition of units of measurement. At the head of the project is Sam Benz, the Quantum Devices Group, which officially presented it on June 9th at a conference on measures of accuracy in Broomfield, Colorado. The new thermometer provides the temperature starting from noise Johnson (hence the name), generated by the random motion of electrons inside a resistance. This measure is directly proportional to the temperature, and the system makes it possible to reduce the error without any additional calibrations. "All measurements are electrical, and do not require volumes of gas or mechanical systems that sometimes, depending on environmental conditions, could give approximate results." says Benz, " beauty is that the measurement is also very simple to perform. "

In the blood of alligators and crocodiles proteins were discovered with high antibacterial and antifungal activity. Unlike men, alligators can combat fungi, viruses and bacteria without the body being previously subjected to these micro-organisms. The researchers have demonstrated the McNeese State University and Louisiana State University who collected the blood from alligators and analyzed the white blood cells, which are the cells appointed to immune defense.

How can you convert waste into energy in the most efficient way possible? The secret is in riboflavin. The microorganisms have the ability to change the chemistry of the environment. This is known for a long time, but if some of these can generate energy from the degradation of organic compounds has not yet been clarified. One answer comes from an American study published in Proceedings of the National Academy of Sciences (Pnas): BioTechnology researchers from the Institute of the University of Minnesota have found that the riboflavin, better known as vitamin B-2, is the key to the production of electricity by the microorganism Shewanella, a bacterium that is commonly found in water and soil.
