Explanation: Galactic or open star clusters are young. These swarms of stars are born together near the plane of the Milky Way, but their numbers steadily dwindle as cluster members are ejected by galactic tides and gravitational interactions. In fact, this bright open cluster, known as M46, is around 300 million years young. It still contains a few hundred stars within a span of 30 light-years or so. Located about 5,000 light-years away toward the constellation Puppis, M46 also seems to contain contradictions to its youthful status. In this pretty starscape, the colorful, circular patch above and right of the...

Flying a kamikaze drone armed with explosives from the back of an MV-22 Osprey aircraft, and directing it right into the insurgent’s fighting hole. The Marines tested a small unmanned aircraft known as the Switchblade recently at Twentynine Palms, Calif., flying it directly at targets from both the ground and the back of the Osprey, a long-range aircraft that has rotors like a helicopter, but can fly like a plane once they rotate forward. They were “inert,” with no explosives on board, but the mission went off without a hitch, said Col. James Adams, commanding officer of Marine Aviation Weapons...

Earth has seen its share of catastrophes, the worst being the “big five” mass extinctions scientists traditionally talk about. Now, paleontologists are arguing that a sixth extinction, 260 million years ago, at the end of a geological age called the Capitanian, deserves to be a member of the exclusive club. In a new study, they offer evidence for a massive die-off in shallow, cool waters in what is now Norway. That finding, combined with previous evidence of extinctions in tropical waters, means that the Capitanian was a global catastrophe. “It’s the first time we can say this is a true...

One-Third of Dutch GP Physicians Would Kill the Mentally Ill Wesley J. Smith April 16, 2015 10:26 AM | Permalink Please! Don't tell me that euthanasia doesn't lead straight off a vertical moral cliff. A recent survey of Netherlander MD general practitioners found that very high percentages would kill cancer patients, and one-third would be willing to euthanize the mentally ill. From the PsychCentral story: For mental illness, only 34 percent would consider helping the patient die, and 40 percent would help someone with early-stage dementia to die. The rate was slightly lower for late-stage dementia, at 33 percent. Only?...

New research that shows poor children have smaller brains than affluent children has deepened the national debate about ways to narrow the achievement gap. Neuroscientists who studied the brain scans of nearly 1,100 children and young adults nationwide from ages 3 to 20 found that the surface area of the cerebral cortex was linked to family income. They discovered that the brains of children in families that earned less than $25,000 a year had surface areas 6 percent smaller than those whose families earned $150,000 or more. The poor children also scored lower on average on a battery of cognitive...

Explanation: While most spiral galaxies, including our own Milky Way, have two or more spiral arms, NGC 4725 has only one. In this sharp color composite image, the solo spira mirabilis seems to wind from a prominent ring of bluish, newborn star clusters and red tinted star forming regions. The odd galaxy also sports obscuring dust lanes a yellowish central bar structure composed of an older population of stars. NGC 4725 is over 100 thousand light-years across and lies 41 million light-years away in the well-groomed constellation Coma Berenices. Computer simulations of the formation of single spiral arms suggest that...

Explanation: It's stars versus dust in the Carina Nebula and the stars are winning. More precisely, the energetic light and winds from massive newly formed stars are evaporating and dispersing the dusty stellar nurseries in which they formed. Located in the Carina Nebula and known informally as Mystic Mountain, these pillar's appearance is dominated by the dark dust even though it is composed mostly of clear hydrogen gas. Dust pillars such as these are actually much thinner than air and only appear as mountains due to relatively small amounts of opaque interstellar dust. About 7,500 light-years distant, the featured image...

'It's going to be the new little wave' For decades, if not centuries, the Amazon dwellers of southern Colombia didn’t make too much of the cacay nut. They fed it to their livestock, used it to treat wounds and chopped down its trees for firewood. But then, a few years ago, the global jet-setting crowd found out what the yellow-ish oil from the protein-rich nut could do for their skin. And suddenly, the cacay (pronounced kahk-ai) has become a red-hot commodity, providing the key ingredient to anti-aging facial creams that can fetch $200 an ounce in beauty shops in Los...

(Phys.org)—Members of a troop of chimpanzees living at a site called Fongoli in southeastern Senegal have been observed by scientists fashioning tree branches into spears and using them to hunt and kill bushbabies. The researchers, a combined team with members from the U.S. the U.K. and Germany have published their observations and findings in Royal Society Open Science. In their seven year study of the chimps living at the site, the researchers spotted chimpanzees breaking off tree branches, tearing off smaller branches and leaves, removing the weak tips and sometimes gnawing on the ends to sharpen them. The spears (which...

Researchers from North Carolina State University and the University of Colorado, Boulder, have developed a statistical model that allows them to tell where a dust sample came from within the continental United States based on the DNA of fungi found in the sample. The primary goal of the research was to develop a new forensic biology tool for law enforcement or archaeologists. "But it may also give us a greater understanding of the invisible ecosystems of microbial life that we know are all around us, but that we don't fully comprehend," says Neal Grantham, a Ph.D. student in statistics at...

There is so much at stake for the charlatans that have foisted the failed “global warming” hoax, followed by the equally dubious claims and predictions regarding “climate change”, that it should come as no surprise that they have begun to wage a propaganda war on the courageous scientists who led the struggle to educate the public about the truth and the organizations who supported their efforts. Along the way, many groups and publications claiming scientific credentials abandoned those standards to pump out global warming and climate change propaganda. Scientists discovered they could secure grant money for “research” so long as...

Published on Feb 6, 2014 Leonard Nimoy explains the Jewish story behind the hand-gesture he made famous through his role as Spock on in the Star Trek science fiction series.

Explanation: What would it look like to fly through a total eclipse of the Sun? On a typical place on Earth in the path of the dark shadow of the Moon during a total eclipse, an observer would see the Moon cross the face of the Sun, completely blocking it for a few minutes. A particularly clear view of the darkness created on Earth during last month's total solar eclipse was captured by an aircraft flying through the Moon's umbral shadow. One second of time in the featured time-lapse video corresponds to about one minute of real time. The Moon's...

Guy named Sam S. was in a storm of trouble when he was caught inside the Tornado in Rochelle IL, Not only was he unlucky but he also screwed up with bad filming, But for liveleak i managed to fix his mistake during the best shot of the video.

Explanation: The view was worth the trip. Battling high winds, cold temperatures, and low oxygen, the trek to near the top of the volcano Santa Maria in Guatemala -- while carrying sensitive camera equipment -- was lonely and difficult. Once set up, though, the camera captured this breathtaking vista during the early morning hours of February 28. Visible on the ground are six volcanoes of the Central America Volcanic Arc, including Fuego, the Volcano of Fire, which is seen erupting in the distance. Visible in the sky, in separate exposures taken a few minutes later, are many stars much further...

Here’s yet another reason to love grilled cheese: Fans of the ooey, gooey sandwiches have more sex, a new study has found. Thirty-two percent of grilled cheese fans have sex at least six times a month, versus 27 percent of those who don't like the sandwich, according to the dating and social-networking site Skout, which released the findings before National Grilled Cheese Day on Sunday.

Certain types of supernovae, or exploding stars, are more diverse than previously thought, a University of Arizona-led team of astronomers has discovered. The results, reported in two papers published in the Astrophysical Journal, have implications for big cosmological questions, such as how fast the universe has been expanding since the Big Bang. Most importantly, the findings hint at the possibility that the acceleration of the expansion of the universe might not be quite as fast as textbooks say. The team, led by UA astronomer Peter A. Milne, discovered that type Ia supernovae, which have been considered so uniform that cosmologists...

Explanation: Who guards the north? Judging from the above photograph, possibly giant trees covered in snow and ice. The featured picture was taken a few winters ago in Finnish Lapland where weather can include sub-freezing temperatures and driving snow. Surreal landscapes sometimes result, where common trees become cloaked in white and so appear, to some, as watchful aliens. Far in the distance, behind this uncommon Earthly vista, is a more common sight -- a Belt of Venus that divided a darkened from sunlit sky as the Sun rose behind the photographer. Of course, in the spring, the trees thaw and...

Conventional agriculture is causing enormous environmental damage in Germany, warns a study by the country’s Federal Environment Agency, saying a transition to organic farming and stricter regulation is urgently needed. EurActiv Germany reports. Spanning over 50% of the country, agriculture takes up by far the biggest amount of land in the country, and is one of its most important economic sectors. But intensive farming still harms the environment to an alarming extent, according to a study conducted by the Federal Environment Agency (UBA). The use of pesticides and fertilizers, as well as intensive animal husbandry, have a negative impact on...

Researchers find that the most common dating method can produce “spuriously old” dates.A team from Europe took a closer look at how uranium-lead ages are determined, and found problems. One of the assumptions going into dating zircons (zirconium silicate crystals encasing uranium that decays to lead) is that the clock is “reset” when the parent rock under goes the high heat and pressure of metamorphism. This team found that nanosphere inclusions of extraneous metallic lead (Pb) can confuse the dating technique, making the rock look older than it is. Writing in PNAS, they say:Zircon (ZrSiO4) is the most commonly used...
