"1987 wurde bekannt, dass Hummeln für die manuelle Bestäubung von Tomaten eine ausgezeichnete Alternative zu Bienen darstellen. Daraufhin hat Koppert sofort mit der Zucht der Erdhummel Bombus terrestris begonnen. Mittlerweile werden Hummeln für die Bestäubung von Tomaten weltweit gezüchtet. Auf diese Weise können die Arbeitskosten deutlich reduziert, die Fruchtqualität verbessert und last but not least der Ertrag gesteigert werden. "

"I am a Neuroscientist working at the Centre for Integrative Neuroscience (CIN), University of Tübingen, Germany. In My Research I use a combination of 2-photon imaging, electrophysiology and computational modelling to unravel principles of synaptic and network computations in the vertebrate early visual system. Outside my regular work I am also co-founder of a not-for-profit organisation TReND in Africa, dedicated to foster Neuroscience Education and Research on the African continent. Moreover I am contributor to Open Labware, the design and building of open source laboratory equipment based on off-the-shelf electronics and simple mechanics as made possible by 3D printing"

"The aim of the project is to get acquainted with usually inaccessible laboratory procedures - extraction of various organic substances and study them further, growing bacteria on agar plates, DNA extraction and sequencing, explant cultures, various behavioral studies (see BrmRat ) and even heredity experiments. A lot of this may be simple stuff you do not need a well-equipped lab for - once we understand the principles, we can make our way forward. Goals The goal of this project is mainly to enable access to experimental biology for everyone interested in it"

To use App Inventor, you do not need to be a professional developer. This is because instead of writing code, you visually design the way the app looks and use blocks to specify the app's behavior.

How tornadoes are predicted days or hours in advance is not easy. There are numerous ingredients that cause tornadoes and go into predicting the possibility for tornadoes.

Two fictitious high-spirited scientists of the institute, passionate surfers, take off to visit the early Universe. Not to do serious research there but to experience the ultimate ride on the plasma waves of the big bang. However, they quickly realize that they would be stuck without their knowledge of the physics of the early Universe.

Supershear earthquakes are the fastest thing underground -- and they tear along hidden superhighways in areas previously not considered at risk

A central point to understanding string theory is that it cannot be formulated the way all other fundamental theories are, by giving the dynamical variables and the equations they obey. We do not know what the fundamental dynamical variables of string theory are, nor the equations they obey.

The spacetime symmetries we discussed in the previous post can be expanded to include three discrete symmetries: parity, charge conjugation, and time-reversal. It turns out (rather surprisingly) that physics chooses not to obey these symmetries, and this act of rebellion allowed the universe to develop interesting things like galaxies and life.

In a recent study, researchers show that a gene called DMRT1 found only on the Z chromosome partly explains bird "maleness". When a ZZ embryo gets less DMRT1, the embryos start to take on some female traits. These studies show us that bird gender can be partly explained by genetics. Not having enough of a single gene can keep a bird from becoming a bona fide male bird. But this doesn't rule out the possibility of a female gene being on the W chromosome. Scientists just haven't yet found one.

New research looks at the effects of studying a form of meditation on brain connectivity. Writing in the Proceedings of the National Academy of Science, researchers in China and the University of Oregon describe experiments on 45 students, some of whom were taught a meditation technique known as integrative body-mind training (IBMT). The researchers used brain imaging techniques to examine fibers connecting brain regions before and after training. Students trained in the IBMT approach for 11 hours or more appeared to develop new fibers in a part of the brain that helps a person regulate behavior. Control subjects did not form the new fibers. But what does the presence of those fibers actually mean -- and what is the meditation technique doing? We'll talk about it.

(AP) -- Floods, fires, melting ice and feverish heat: From smoke-choked Moscow to water-soaked Pakistan and the High Arctic, the planet seems to be having a midsummer breakdown. It's not just a portent of things to come, scientists say, but a sign of troubling climate change already under way.

Not quite there yet for human teleportation, but at least they are thinking about it.

The Santa Fe Institute is a private, not-for-profit, independent research and education center founded in 1984, for multidisciplinary collaborations in the physical, biological, computational, and social sciences. Understanding of complex adaptive systems is critical to addressing key environmental, technological, biological, economic, and political challenges.

ScienceDaily (Sep. 3, 2010) - Ants are not out of their weight class when defending trees from the appetite of nature's heavyweight, the African elephant, a new University of Florida study finds.

A stuffed teddy bear that appears as if it?s inhaling and exhaling was designed by researchers to comfort fussy babies in the crib, but it seems to work even better for their mothers, a new study reveals. According to the mothers? estimates of crying time, babies who spent five months snuggling with ?Breathing Bear? did not cry any less than infants who shared their crib with a regular stuffed bear, say Evelyn B. Thoman, Ph.D., and Claire Novosad, Ph.D., of the University of Connecticut. But mothers of the Breathing Bear babies reported less depression and stress and described their infants as less fussy and difficult.

A new study in The Lancet rates the harmfulness of 20 psychoactive drugs according to 16 criteria and finds that alcohol comes out on top. Although that conclusion is generating headlines, it is not at all surprising, since alcohol is, by several important measures (including acute toxicity, impairment of driving ability, and the long-term health effects of heavy use), the most dangerous widely used intoxicant, and its abuse is also associated with violence, family breakdown, and social estrangement. A group of British drug experts gathered by the Independent Scientific Committee on Drugs (ISCD) rated alcohol higher than most or all of the other drugs for health damage, mortality, impairment of mental functioning, accidental injury, economic cost, loss of relationships, and negative impact on community. Over all, alcohol rated 72 points on a 100-point scale, compared to 55 for heroin, 54 for crack cocaine, and 33 for methamphetamine. Cannabis got a middling score of 20, while MDMA (Ecstasy), LSD, and psilocybin mushrooms were at the low end, with ratings of 9, 7, and 6, respectively.

According to a new study in Current Directions in Psychological Science, a journal of the Association for Psychological Science, regular gamers are fast and accurate information processors, not only during game play, but in real-life situations as well.

Based on a theory developed by Prof. Rosenberg and Dr. Ilana Zilber-Rosenberg, the scientists propose that the basic unit of natural selection is not the individual living organism, plant or animal, but rather a larger biological milieu called a holobiont. This milieu can include plant or animal life as well as their symbiotic partners. In the case of animals, these partners tend to be microorganisms like intestinal bacteria.
