Conspiracy theorists have claimed this photo is proof that the lunar program was a hoax because no stars are visible in the shot. Unfortunately for those nay-sayers, this is due to the overexposure of the camera, not a lunar conspiracy.

Lead researcher Gary Stobel, a plant scientist from Montana State University said of the discovery "This is the only organism that has ever been shown to produce such an important combination of fuel substances, we were totally surprised to learn that it was making a plethora of hydrocarbons."

Mr Dominic Thompson, a consultant paediatric neurosurgeon at London's Great Ormond Street Hospital, said there were probably less than 100 recorded cases of foetus in foetu in the medical literature. Sam was operated on without any problems, and all that is remaining of this little foot, is a little scar.
Images taken by the high resolution CRISM spectrometer on NASA's Mars Reconnaissance Orbiter in a recent study by Brown University have broken new ground in the age-old question of whether or not Mars could have at one point sustained life. The discovery of magnesium carbonate rocks in several research sites is important because these carbonate minerals form in the presence of water, and for the first time the research has suggested that they formed in neutral-pH water that would have provided an ideal environment for living organisms.
Lead Astronomer Bethany Ehlmann says "Such water represent a different sort of aqueous environment -- potentially a habitat for micro-organisms -- on ancient Mars."
In some regions where research has been conducted on the surface of Mars, it is clear that acidic waters were at one point present, and it was assumed that this was the case for most of the planet. Astronomers are eager to study the wide range of possible environments this discovery has proven there could be on the planet, and arduously continue to prove the existence of life on Mars.
John Mustard, another member of the Brown University team added "This is opening up a range of environments on Mars. This is highlighting an environment that to the best of our knowledge doesn't experience the same kind of unforgiving conditions that have been identified in other areas. We know there's been water all over the place, but how frequently have the conditions been hospitable for life? We can say pretty confidently that when water was present in the places we looked at, it would have been a happy, pleasant environment for life."
The head of research and development at biotechnology firm Bio Sidus, Andres Bercivich, explained that if under normal circumstances a cow produces 20 liters of milk/day, it could produce 25 liters when injected with this hormone. When looking at one cow, it might not seem like much, but convert that statistic to the output levels at huge milk firms, an increase of 25% will equal a huge jump in profits.
The company plans to export the dairy hormone technology to the United States, Mexico, Peru, and Brazil, as this product has not yet been approved for sale in Argentina.
Now I will take this opportunity to introduce a new member to Markit Science team: the one and only Millkit

The fireball seen in the video above was captured by a peace officer's dashboard cam in Devon, Alberta, providing an excellent account of this event. The meteorite fall occurred on 2008 November 20 at 5:26.42 MST. It was seen by thousands of people across the Canadian prairies, sparking a wide range of reactions from sheer awe to fear and panic.
Thousands of meteorites are expected to have rained down over a 20 square km area, but they were difficult to find in the varied terrain of Buzzard Coulee. After quick examination of the suspected region of impact, the first meteorites were located by Ellen Milley, a PhD candidate at the University of Calgary, in a frozen fish pond near the agricultural community of Lone Rock, Saskatchewan.
The largest meteorite fragment to be recovered in the first days was a 13 kg whopper which creating a form fitting indentation 5-10 cm deep before bouncing out and resting on the frozen ground a few cm away. Take a look at the detailed topographical map to see the exact impact location of the large meteorite.

Parker taught in a two-room school in Shelby County for several years after graduating from Franklin College in 1911. She wed her childhood sweetheart and neighbour in 1913. Two years ago she was named as the oldest living person by Guinness Book of World Records. She never drank alcohol or tried tobacco, and led a very active lifestyle, but when asked about tips to longevity, her only advice was "more education".
Now the oldest person is Maria de Jesus of Portugal, born September 10, 1893, who is currently 115 years, 78 days old.

Holoprosencephaly (HPE) refers to a range of problems involving the malformation of the brain and upper face along the midline. In the most moderate of circumstances, the signs of HPE are as subtle as one single central incisor, shown above on the left. The most extreme end of the spectrum can be associated with midline cleft lip, cyclopia, and an overlying proboscis, shown above on the right. The proboscis, which is the build-up of tissue seen above the eyes, forms because of the obstruction by the central eye. It is made up of frontonasal neural-crest cells that would have normally migrated between the eyes to form the nose and upper lip.
This is extremely rare in live births (~1 in 15,000), but is more commonly detected in early pregnancies (1 in 250); however almost all affected fetuses are miscarried. The cause of these deformities is thought to be due to mutations in the SHH gene.

These little nocturnal creatures weigh less than 60 grams and have dense fur that keeps them warm in their cold habitat at high altitudes. Its eyes cannot move, so when hunting for small insects or vertebrates it turns its head 180 degrees. Unlike other primates it has claws, rather than nails.

"But in dead cells the cell membrane is broken and the fusion method cannot be used for cloning. In our method, it does not matter whether the donor cells are alive or dead," Wakayama explained.The technique could eventually lead to the resurrection of extinct animals such as the woolly mammoth, scientists stated in November 2008.

"PERSONS NOT HEEDING EVACUATION ORDERS IN SINGLE FAMILY ONE OR TWO STORY HOMES WILL FACE CERTAIN DEATH. MANY RESIDENCES OF AVERAGE CONSTRUCTION DIRECTLY ON THE COAST WILL BE DESTROYED. WIDESPREAD AND DEVASTATING PERSONAL PROPERTY DAMAGE IS LIKELY ELSEWHERE."
10's of thousands of people are already on the roads getting out of there. I will update the situation as news comes in.

It is estimated that these toads migrate at an average of 40 km per year. This is making people nervous since they are starting to destroy flora, as well as other species, such as the Northern Quoll and certain snakes. To get an idea of how they are spreading, see the map below:
Recently some researchers have made progress predictions regarding the migration of this explosively breeding species. In the spirit of the recent Olympics, scientists have staged a 2 meter sprint event in a laboratory setting. The Ecography journal reports that Toads could hop as fast as 2km per hour at 30C, but were only able to hop at 0.3 km per hour at 15C.
Previous studies have predicted that southern regions of Australia, including Melbourne, will eventually face the toad invasion. Head researcher Dr. Kearney feels otherwise: "The cane toads cannot survive in much of southern Australia because they would be too cold to move about and forage or spawn." Perhaps these cold temperatures will halt the progress of the toad army after all.

So what's the big deal? Blackle argues that computer monitors use different amounts of energy dependent on what colors they are showing. In a 2002 study, they determined that an all black screen used less energy than an all white screen. Although this might be insignificant during your own 30 second search, think of the billions of hits that Google receives. Blackle creators estimate that a black Google would save 750 megawatt hours per year. To put that in perspective, 1 megawatt hour is the equivalent of 10,000 hundred-watt light bulbs turned on for 1 hour. On the Blackle Homepage they have a counter showing the number of watt hours saved. As of August 28, 2008 they claim to have saved 793,544.792 watt hours.

On August 8, 2008, deputy Brandon Riedel used his dashboard camera to film an unidentifiable animal along some back country roads near Cuero, Texas. The animal was similar to a coyote in size, but was hairless and had a very long snout. There was brief coverage regarding the video on FOX, check it out:

"We are a little perplexed at this point, to tell you the truth," the Ventura County Star quoted geologist David Panaro as saying. "This is not your usual geological detective story."
One theory is that natural hydrocarbons, such as oil, are burning deep in the earth and seeping out through cracks in the region, forcing the surface to quickly heat and generate smoke. Allen King, a former geologist with the U.S. Forest Service recently stuck a thermometer into the ground and got a reading of 550 degrees — so hot that it melted the glue holding the sole of his boots together.

The safe return of 2 submersibles (Mir-1 and Mir-2) set a new record by descending 1680 meters. Before this, it was thought that Lake Baikal was only 1637 meters deep. They were taking samples from the bottom to further their studies of plants and animals.
Some skeptics might argue that they were really examining potential entrance paths for oil. Igor Chestin, the head of WWF Russia, commented on possible oil exploration by saying, "I think scientists as well as the politicians are enough educated to understand that even if all oil of the planet will be down the lake Baikal, it still will not be worth exploring, because the fresh water is going to be the major resource in the coming decade."

Jeff Corwin, wildlife expert from 'Animal Planet', has a simple theory. He claims that it's a raccoon with its muzzle partly rotted away, explaining the beak-like snout. With enough erosion, the canine teeth could easily resemble a beak like structure.
William Wise, director of Stony Brook University's Living Marine Resources Institute, disagreed after consulting with fellow biologists. He isn't sure what it is, but he has ruled out some options:
- raccoon - the legs are too long in proportion to the body
- sea turtle - they don't have teeth
- rodent - rodents have two large, curved incisor teeth in front of their mouths
All of this is based on photograph analysis, because the actual body has yet to land in the laps of scientists. The photographer, 26 year old Jenna Hewitt, explained its current whereabouts stating that, "A guy took it and put it in the woods in his backyard; he has a big backyard." She wouldn't say who, and wouldn't say where. Sounds fishy?
Here's the other picture that was taken. I'm on the raccoon train...

"We like to boast that we're the polar bear capital of the world, with all of the polar bears up at Churchill and along the coast," zoo curator Bob Wrigley said.
She spent years living in her enclosure with her former mate Skipper, who died six years ago. Zoo keepers claim that they would huddle together outside through the night, even in -40 C. temperatures. In the morning, they would wake up completely covered in snow drifts, Wrigley said. Their long relationship was unusual for the usually solitary animals. Although options aren't too extensive when living in a zoo.
Unfortunately for Debby, her old age is catching up, and reports have been made that she is dying from age-related medical complications. She has suffered several strokes and is losing weight. Her "prognosis of recovery from age-related medical problems is not good," the zoo said in a release. Get better Debby!

For those located in Eastern Canada, the last partial solar eclipse visible was 9 years ago, 1999 August 11, and it also occurred at sunrise. There was a more recent solar eclipse on Christmas Day 2000, but clouds and snow hid it. After tomorrow, the next partial solar eclipse visible from this area will happen on November 3, 2013.
To see tomorrow's unusual sunrise, be ready for an early wake up, as the period of total eclipse, or totality, will occur from 7:08am to 7:10am EDT. You will need a proper solar filter to avoid damaging your eyes, or use a pinhole mirror projector. But if you sleep through the alarm, fear not, NASA has you covered. They will be providing a live feed of the event. The coverage, originating in China and reliant on good weather, runs from 6:00am to 8:15am EDT. Follow this link to see it happen!

Two large tornado-like waterspouts were spotted over Montreal on June 23rd as a result of an approaching severe thunderstorm. Environment Canada confirmed that the first waterspout formed in Montreal's east end at 1:15 pm ET in the St. Lawrence River. Simultaneously, a second waterspout formed about 70 km northeast of the city.
This "waterspout" is a spinning funnel column of water and vapour that forms between a cloud and the earth. Generally they are weaker than a tornado, and usually occur in tropical regions. They are frequently reported in areas like Florida, off the coast of Key West.

Scientists estimate that 30 to 40 of the lemurs live in the swampy region, where bamboo is plentiful. These wrinkly faced creatures are known for cracking open giant bamboo with their industrial-strength jaws. Perhaps a pocket population strayed south to escape habitat destruction from illegal logging, which is common in the north.

By exposing the vocal muscle fibers to electrical stimulation, scientists clocked how fast the muscles expanded and contracted. Both female and male starlings moved at about 3.2 milliseconds per expansion or contraction. In zebra finches, females moved at 7.1 milliseconds, while males twitched at 3.7.
There are some competitors elsewhere in the natural world. Rattlesnakes come in a close second with the twitching muscles on both sides of their rattler. The muscles in swim bladders of certain fish also move strikingly fast.
"We had no idea muscles could work at these superfast rates," said Daniel Margoliash, a biologist at the University of Chicago. "That they can and do is just amazing."

The US Apollo missions in the late 1960s and early 1970s successfully collected lunar volcanic glasses, pebble-like beads. Since then scientists have been determining the nature of the chemical elements in the glasses.
Using secondary ion mass spectrometry (SIMS) technology, the team from Brown University, the Carnegie Institution for Science, and Case Western Reserve University, were able to detect extremely tiny amounts of water in glasses and minerals.
"We were really surprised to find a whole lot more in these tiny glass beads, up to 46 parts per million," said Erik Hauri, from the Carnegie Institution in Washington DC.They think that the water was contained in magma which erupted via "fire fountains" on the lunar surface more than 3 billion years ago. The eruptions themselves would have evaporated 95% of the water, but also leave some behind. Since the Moon's gravity is too weak to have an atmosphere, speculations indicate that some of the water vapour was likely forced into space. But some might have drifted towards the cold poles of the Moon, where ice may exists in constantly shadowed craters.

“Sterilization is not a requirement for sex reassignment, so I decided to have chest reconstruction and testosterone therapy but kept my reproductive rights,” he writes. “Wanting to have a biological child is neither a male nor female desire but a human desire.”
As expected, this whole ordeal has garnered much attention. Mr. Beatie announced his pregnancy in April on the Oprah Winfrey show. He also plans to write a book about the entire experience. A hospital source said that the baby is healthy and the mother/father has been permitted to leave the hospital.

So just how good is this fuel efficiency? Lets compare it with the top selling cars in the US during January of this year: Toyota Camry and Honda Accord. The Toyota Camry will squeeze out 35 MPG on the highway, while the Accord maxes out at 29 MPG.
So how do they do it? The 1 Liter car weighs only 660 pounds, and is made from a body of carbon composites. Due to its slippery shape, it has a coefficient drag of only 0.16 (the average car is about 0.30). The prototype was powered by a 1-cylinder diesel engine, but the soon to be released model should be equipped with a 2-cylinder, and perhaps a stop-start anti-idling feature.
Until we can produce a completely new method, we might as well improve on the one that's around now. It might not be available to the masses yet, but it's certainly a step in the right direction.

In more detail... The fungus spores first attach themselves to the surface of the ant, where they germinate. They then invade the ant's body through the tracheae, allowing for fine fungal filaments called mycelia to start growing. When the fungus is ready to sporulate, the mycelia grow into the ant's brain, and produce chemicals which act on the brain to alter their perception of pheromones. This makes the ant climb a plant and, after reaching the peak, to clamp its mandibles around a leaf or leaf stem. This becomes the ant's final resting place.
The fungus eats through the brain, killing the host. The fungal fruiting bodies sprout from the ant's head, through gaps in the joints of the exoskeleton. When mature, the fruiting bodies burst and release capsules into the air. These explode on their way down, effectively spreading airborne spores over the area below. These spores infect other ants, completing the fungal life cycle. Depending on the type of fungus and the number of infecting spores, death of an infected insect takes 4 to 10 days.

The cracker has much less mass than the handle section of the bullwhip. When it is sharply snapped, the energy is transferred down the length of the whip. The velocity of the whip increases with the decrease in mass, which is how the whip reaches the speed of sound and causes a sonic boom.

Condo reservations are already being taken, but they won't be ready until 2010, and will cost from $3.7 million to $36 million ($3000/square foot). Penthouses will be able to control the rotation of their own units, but the designers control the lower floor. Another one is being planned for completion in Moscow before 2011, and possibly a third in New York City.
The construction scheme is just as impressive as the building itself. Each story will be made from prefabricated parts. The rooms will be assembled in a workshop, shipped to the site, and attached to the building's spine. Check the video below:
It is actually quite simple to make a car appear as if it runs on water. How? Through the use of metal hydrides, which react with water to produce hydrogen, in turn powering the vehicle. But with time these hydrides start to deplete and eventually need to be replaced. So in a way the hydrides are the fuel, not the water. More energy goes into producing such hydrides than they can produce themselves.
Apologies for falling into the trap of presenting misleading information. Perhaps a more suitable title for the vehicle would have been 'Hydride Car'.

The photograph above shows members of a tribe on the border of Peru and Brazil firing arrows at a passing airplane. Although the name of the tribe is unknown, apparently they have been being monitored by the Brazilian government for decades. That being said, nobody has ever had face-to-face contact with the tribe, so who knows how much they know about the outside world. However, judging by the fact that they think their arrows will do damage to a passing airplane, chances are they don't know too much about what is happening outside of their jungle region.
A few things are known about this enigmatic tribe. They have shaved foreheads and long hair. They plant cotton, or pick it growing in the jungle, and spin it into cloth for skirts. The women make cotton belts and headbands. Also, they make hammocks that are hung below huts covered by thick palm roofs.
"They have big fields, and they grow cassava, maize, almonds, pumpkin, and various types of potato, papaw, yams, and banana," according to José Carlos Meirelles, an official with Brazil's Indian-protection agency (FUNAI). Check the video below for more insight:

The photograph above, and the other below, were taken in 2002 by Tony Travouillon at the Antarctic Base of Dumont D'Urville. To dispel another myth, these do not occur on Lake Huron. In March of 2008 these same images were found all over the internet accompanied by text claiming that the waves were found on Michigan's Lake.

The WES extracts hydrogen from the water as it is running, and an on-board generator releases electrons to power the car. Genepax hopes to start mass production with a major car manufacturer. This soon-to-be patented WES should be making quite the splash worldwide, but the lack of media attention is shocking.
According to their low quality English website they are "preparing an English presentation and demonstration for foreign press which will be held in Tokyo soon". Until then, check out the video below to see the car in action.

"We have received so many calls from people, and many are coming to see it," said Gilberto Tozzi, director of the Center of Natural Sciences in Prato, northwest of Florence. "Sometimes he comes close to the fence, even if he is very shy."
Single horned deer are very rare, but not unheard of, however its central positioning is unusual. Tozzi suggests that similar mutations in the past might have inspired the unicorn myth.

That same year the international whaling institute banned the hunting of humpbacks, and over the past half-century global conservation efforts have increased dramatically. A new collaborative effort, involving over 400 whale experts in the Pacific region, reveals that the population has rebounded to over 20,000 animals.
"While I agree that conservation concerns are not eliminated, this is fundamentally a good-news story," said Jay Barlow, a co-author from the National Oceanic and Atmospheric Administration's Southwest Fisheries Science Center in La Jolla, California.
"If the world had more examples like this, I think that the people of the world would be more inclined to believe that conservation can make a difference."
