Graphene is the material of the future, it could even help us to achieve invisibility. So what could it mean for your smartphone?

Scientists, engineers and tech-addicts everywhere are getting very excited about Graphene. It may sound like the stuff you get in your pencils but this newly discovered material could help us enter an entirely new technological age. Work is already underway to make invisibility a possibility – all thanks to the wonders of Graphene. (more…)

Deutsch-russische Partnerschaft zum Schutz des “Russischen Amazonas”

Die Naturschutzorganisation WWF zieht nach fünf Jahren eine positive Bilanz des deutsch-russischen Kooperationsprojekts zum Schutz der letzten Urwälder im Fernen Osten Russlands. Im Rahmen des Bikin-Projektes wurde der indigene Volkstamm der Udege seit Mitte 2008 darin unterstützt, die Wälder entlang des Bikin-Flusses nachhaltig zu nutzen und zu schützen und somit deren Abholzung zu verhindern.

Für das Bikin Projekt wurde zudem ein innovativer Finanzierungsmechanismus entwickelt. Erlöse aus dem Verkauf von Kohlenstoff-Zertifikaten sollen langfristig den Schutz der Wälder absichern. Aus dem nun erfolgten Verkauf solcher Zertifikate wurden dafür 395.000 Euro erlöst. (more…)

HIV plus HPV leads to increased anal cancer risk in men

Human papillomavirus, or HPV, which can cause cervical cancer in women, is also known to cause anal cancer in both women and men. Now, a study led by researchers at the UCLA School of Nursing has found that older HIV-positive men who have sex with men are at higher risk of becoming infected with the HPVs that most often cause anal cancer.

The researchers also report that smoking increases the risk of infection with specific types of HPV among both HIV-infected and uninfected older men by up to 20 percent. This is the first large U.S. study of a group of HIV-infected and uninfected men between the ages of 40 and 69 who have sex with men. Study participants were examined twice a year for up to 25 years.

Neuroscience Methods: Optogenetics as good as electrical stimulation

Brown researchers have shown that optogenetics — a technique that uses pulses of visible light to alter the behavior of brain cells — can be as good as or possibly better than the older technique of using small bursts of electrical current. Optogenetics had been used in small rodent models. Research reported in Current Biology has shown that optogenetics works effectively in larger, more complex brains.

PROVIDENCE, R.I. [Brown University] — Neuroscientists are eagerly, but not always successfully, looking for proof that optogenetics – a celebrated technique that uses pulses of visible light to genetically alter brain cells to be excited or silenced – can be as successful in complex and large brains as it has been in rodent models.

An interdisciplinary UA team is developing a computer program that will sort through up to 10 million alerts of astronomical objects each night from the Large Synoptic Survey Telescope, which will begin operations in Chile in 2022

University of Arizona computer scientists are teaming up with astronomers at the National Optical Astronomical Observatory to develop a computer program that will sort through the millions of objects detected by the Large Synoptic Survey Telescope and create a list of priorities for astronomers to investigate. The project has recently received a three-year INSPIRE grant, worth more than $700,000, from the National Science Foundation. (more…)

Photojournalists discuss their project on a ‘sacrificial city’

There’s a city in America that looks like a third-world country, according to photojournalists Brett Carlsen and Juan Madrid, who in a recent campus talk shared their hope that a project they have undertaken will inspire the American public to start talking about it.

In a Poynter Fellowship-sponsored classroom lecture at the School of Art, Carlsen and Madrid discussed their ongoing collaboration documenting life in Flint, Michigan. (more…)

Angriff aus Brüssel gegen Energiewende abwehren. EEG-Beihilfeverfahren ist erste Herausforderung für Gabriel und Merkel

Berlin: Der Bund für Umwelt und Naturschutz Deutschland (BUND) hat Wirtschafts- und Energieminister Sigmar Gabriel und Bundeskanzlerin Angela Merkel aufgefordert, das Erneuerbare-Energien-Gesetz (EEG) und die Energiewende gegen aktuelle Angriffe der EU-Kommission zu verteidigen.

“Setzt sich die EU-Kommission durch, ist nicht nur in Deutschland die Energiewende bedroht. Denn zusätzlich zum Beihilfeverfahren will die EU-Kommission neue restriktive Vorgaben zur Förderung der erneuerbaren Energien erlassen. Das würde den Ausbau der regenerativen Energien europaweit abbremsen”, sagte der BUND-Vorsitzende Hubert Weiger. (more…)
