Biodiversität: Seltene Arten helfen Ökosystemen - SPIEGEL ONLINE - 0 views

"Seltene Tier- und Pflanzenarten sind für das Funktionieren eines Ökosystems oft extrem wichtig - weil sie Merkmale oder Eigenschaften haben, über die keine oder nur wenige andere Arten in ihrem Lebensraum verfügen. Der Verlust solcher Arten treffe das Ökosystem deshalb als Ganzes schwer, schreibt ein internationales Forscherteam im Fachmagazin "PloS Biology". Auch Artenschutzbemühungen - etwa im Rahmen des Weltrats für biologische Vielfalt - sollten das berücksichtigen, so die Forderung der Wissenschaftler. "

"Wussten Sie beispielsweise, dass Spinnenseide fünf Mal reißfester als Stahl, sowie extrem stabil und elastisch ist? Das sind Eigenschaften, die sich die Medizin zu Nutzen machen will. Da die Seide nämlich vom Körper nicht als fremd erkannt wird und daher eine Immunabwehr ausbleibt, arbeiten Wissenschaftler daran, aus dem Material Nerven von Unfallopfern zu rekonstruieren - etwa bei einer Querschnittslähmung. Erste vielversprechende Erfolge können sie im Tierversuch bereits vorweisen. Doch damit nicht genug. Mediziner wollen Spinnenseide außerdem dazu benutzen, künstliche Haut und verschiedene Implantate zu züchten"

"Manche sehen ein helles Licht, andere erleben Stationen ihres Lebens noch einmal im Schnelldurchlauf: Viele Menschen, die kurzzeitig klinisch tot waren, dann aber gerettet wurden, berichten von intensiven Nahtod-Erfahrungen. Woher diese Gefühls- und Sinneseindrücke kommen und wie sie sich biologisch erklären lassen, war bisher allerdings umstritten. Ein Experiment von US-Forschern an Ratten belegt nun: Diesen Erfahrungen liegt tatsächlich ein messbarer neurologischer Effekt zugrunde. Nach einem Herzstillstand erlebt das Gehirn eine kurze Phase extrem koordinierter Aktivität, die sogar stärker ist als im wachen Zustand. "

Astronomers discover complex organic matter in the universe | KurzweilAI - 1 views

Organic compounds of unexpected complexity exist throughout the universe, Prof. Sun Kwok and Dr. Yong Zhang of the University of Hong Kong have discovered, suggesting that complex organic compounds can be synthesized in space even when no life forms are present. The organic substance they found contains a mixture of aromatic (ring-like) and aliphatic (chain-like) components that are so complex, their chemical structures resemble those of coal and petroleum. Since coal and oil are remnants of ancient life, this type of organic matter was thought to arise only from living organisms. Unidentified radiation from the universe The researchers investigated an unsolved phenomenon: a set of infrared emissions detected in stars, interstellar space, and galaxies, known as "Unidentified Infrared Emission features." From observations taken by the Infrared Space Observatory and the Spitzer Space Telescope, Kwok and Zhang showed that the astronomical spectra have chemical structures that are much more complex that previously thought. By analyzing spectra of star dust formed in exploding stars called novae, they show that stars are making these complex organic compounds on extremely short time scales of weeks, and ejecting it into the general interstellar space, the region between stars. "Our work has shown that stars have no problem making complex organic compounds under near-vacuum conditions," says Kwok. "Theoretically, this is impossible, but observationally we can see it happening." Most interestingly, this organic star dust is similar in structure to complex organic compounds found in meteorites. Since meteorites are remnants of the early Solar System, the findings raise the possibility that stars enriched the early Solar System with organic compounds. The early Earth was subjected to severe bombardments by comets and asteroids, which potentially could have carried organic star dust. Whether these delivered organic compounds played any role in the development of l

Drury, a geneticist, is a pioneer in new research exploring the biological impacts of early adversity on children. She is the first scientist to show that extreme stress in infancy can biologically age a child by shortening the tips of chromosomes, known as telomeres. These caps keep chromosomes from shrinking when cells replicate. Shorter telomeres are linked to higher risks for heart disease, cognitive decline, diabetes and mental illness in adults.

ScienceDaily (Sep. 12, 2011) - The HARPS spectrograph on the 3.6-metre telescope at ESO's La Silla Observatory in Chile is the world's most successful planet finder [1]. The HARPS team, led by Michel Mayor (University of Geneva, Switzerland), have announced the discovery of more than 50 new exoplanets orbiting nearby stars, including sixteen super-Earths [2]. This is the largest number of such planets ever announced at one time [3]. The new findings are being presented at a conference on Extreme Solar Systems where 350 exoplanet experts are meeting in Wyoming, USA.

Use of DNA evidence is not an open and shut case, professor says - 0 views
-
In his new book, "The Double Helix and the Law of Evidence" (Harvard University Press), Kaye focuses on the intersection of science and law, and emphasizes that DNA evidence is merely information. "There's a popular perception that with DNA, you get results," Kaye said. "You're either guilty or innocent, and the DNA speaks the truth. That goes too far. DNA is a tool. Perhaps in many cases it's open and shut, in other cases it's not. There's ambiguity."
-
One of the book's key themes is that using science in court is hard to do right. "It requires lawyers and judges to understand a lot about the science," Kaye noted. "They don't have to be scientists or technicians, but they do have to know enough to understand what's going on and whether the statements that experts are making are well-founded. The lawyers need to be able to translate that information into a form that a judge or a jury can understand." Kaye also believes that lawyers need to better understand statistics and probability, an area that has traditionally been neglected in law school curricula. His book attempts to close this gap in understanding with several sections on genetic science and probability. The book also contends that scientists, too, have contributed to the false sense of certainty, when they are so often led by either side of one particular case to take an extreme position. Scientists need to approach their role as experts less as partisans and more as defenders of truth. Aiming to be a definitive history of the use of DNA evidence, "The Double Helix and the Law of Evidence" chronicles precedent-setting criminal trials, battles among factions of the scientific community and a multitude of issues with the use of probability and statistics related to DNA. From the Simpson trial to the search for the last Russian Tsar, Kaye tells the story of how DNA science has impacted society. He delves into the history of the application of DNA science and probability within the legal system and depicts its advances and setbacks.
Exotic Antimatter Created on Earth - Yahoo! News - 0 views

Among the many particles that resulted from this crash were bizarre objects called anti-hypertritons. Not only are these things antimatter, but they're also what's called strange matter. Where normal atomic nuclei are made of protons and neutrons (which are made of "up" quarks and "down" quarks), strange nuclei also have so-called Lambda particles that contain another flavor of quark called "strange" as well. These Lambda particles orbit around the protons and neutrons. If all that is a little much to straighten out, just think of anti-hypertritons as several kinds of weird. Though they normally don't exist on Earth, these particles may be hiding in the universe in very hot, dense places like the centers of some stars, and most likely were around when the universe was extremely young and energetic, and all the matter was packed into a very small, sweltering space. "This is the first time they've ever been created in a laboratory or a situation where they can be studied," said researcher Carl Gagliardi of Texas A&M University. "We don't have anti-nuclei sitting around on a shelf that we can use to put anti-strangeness into. Only a few anti-nuclei have been observed so far." These particles weren't around for too long, though – in fact, they didn't last long enough to collide with normal matter and annihilate. Instead they just decayed after a fraction of a billionth of a second. "That sounds like a really short time, but in fact on the nuclear clock it's actually a long time," Gagliardi told SPACE.com. "In that fraction of a billionth of a second that Lambda particle has already gone around the nucleus as many times as the Earth has gone around the sun since the solar system was created."

Scientists have created a never-before seen type of exotic matter that is thought to have been present at the earliest stages of the universe, right after the Big Bang. The new matter is a particularly weird form of antimatter, which is like a mirror-image of regular matter. Every normal particle is thought to have an antimatter partner, and if the two come into contact, they annihilate. The recent feat of matter-tinkering was accomplished by smashing charged gold atoms at each other at super-high speeds in a particle accelerator called the Relativistic Heavy Ion Collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory in Upton, N.Y.
