Suggestions that global warming has stalled are a "diversionary tactic" from "deniers" who want the public to be confused over climate change, according to the world's best-known climate scientist. Prof James Hansen, who first alerted the world to climate change in 1988, said on Friday: "It is not true that the temperature has not changed in the two decades."
We all know that animals with rabies are nutty, aggressive, and prone to biting new victims. The rabies virus is transmitted to a new carrier whenever the mad sufferer attacks and bites somebody or thing. The new carrier then becomes nutty, ...
A 2.6-billion-year-old pocket of water, the oldest yet found, has been discovered deep underground and could shed light on early Earth life and the possibility of life on Mars.
The foxes she worked with come from a long line started in 1959 when a Russian scientist named Dmitry Belyaev attempted to recreate dog domestication, but using foxes instead of wolves. He bred silver foxes (Vulpes vulpes), which are actually a type of red fox with white-tipped black fur. Belyaev and his colleagues selected the least aggressive animals they could find at local fox farms and bred them. Each generation, the scientists picked the tamest animals to mate, creating ever friendlier foxes. Now, more than 50 years later, the foxes act like dogs, wagging their tails, jumping with excitement and leaping into the arms of caregivers for caresses.
Neuroscientist Henry Markram says he can build a supercomputer replica of the human brain. Now he has $1.3 billion to prove it.
A group of scientists from the University of Alberta have created a process that makes graphene-like nanomaterials out of hemp waste, suitable for use in supercapacitors.
Human cloning is used to produce early embryos, marking a "significant step" for medicine, say US scientists.
Genes overlap, share regulatory sequences in order to compact the genome.

Space station commander, Chris Hadfield, tells BBC News that those calling for a quick return of manned missions to the Moon were seeking "titillation".
British scientists at a research centre in Cambridge say they have developed a new type of wheat which could increase productivity by 30%.
Researchers show that plants can communicate the need to protect themselves from attack by aphids by making use of an underground network of fungi.
Thousands of meteorites have collided with the Earth since 2500 BC. 34,842 have been recorded. Only 1,045 have been seen falling.
There's a theory that human intelligence stems from a single algorithm. The idea arises from experiments suggesting that the portion of your brain dedicated to processing sound from your ears could also handle sight for your eyes. This is possible only while your brain is in the earliest stages of development, but it implies that the brain is -- at its core -- a general purpose machine that can be tuned to specific tasks.

It is one of the most unusual evolutionary ideas ever proposed: humans are amphibious apes who lost their fur, started to walk upright and developed big brains because they took to living the good life by the water's edge.
Using a delicious combination of particle accelerators, X-rays, high-intensity lasers, diamonds, and iron atoms, scientists have worked out that the inner core of the Earth is actually 6,000 degrees Celsius — some 1,000 degrees hotter than the previous scientific estimate. This means the core of our Earth is actually hotter than the surface of the Sun. This new data could generate repercussions in the fields of geophysics, seismology, geodynamics, and other Earth-oriented scientific disciplines.
Monkeys are just as prone to peer group pressure as humans, according to new research.

The 2K Network has just published a major paper in Nature Geoscience, with 78 researchers contributing as co-authors from 60 separate scientific institutions around the world. Their two main results are a confirmation that current global surface temperatures are hotter than at any time in the past 1,400 years, and that while the Medieval Warm Period (MWP) and Little Ice Age (LIA) are clearly visible events in their reconstruction, they were not globally synchronized events.

Here’s the iconic Horsehead Nebula as we’ve not seen it before. As the Hubble team so poetically puts it, the nebula looks “like an apparition rising from whitecaps of interstellar foam.” The new image of the Horsehead was photographed in celebration of the 23rd anniversary of the launch of Hubble aboard the space shuttle Discovery, on April 24, 1990.

As life has evolved, its complexity has increased exponentially, just like Moore’s law. Now geneticists have extrapolated this trend backwards and found that by this measure, life is older than the Earth itself.
