""Anti-Gravity Hills" (also known as "Gravity Hills", "Spook Hills", or "Magnetic Hills") are natural places where cars put into neutral are seen to move uphill on a slightly sloping road, apparently defying the law of gravity. Typically, the "spooky" stretch of road is rather short (50-90 m), only a few meters wide, and surrounded by a natural hill landscape, without nearby buildings. Such places are found in several countries all around the world, and have been tourist attractions for decades. They should not be confused with the "Mystery Spots" [previously] found in amusement parks. These are generally tilted cabins, purposely built as such; a person walking inside feels disoriented, getting a very strong impression of standing at an angle in a perfectly normal room." CSICOP and Discovery News explain the phenomenon, and here's the paper on which the CSICOP article was based (PDF).

Cool app lets you zoom in from a coffee bean to a carbon atom, so that you can compare sizes. Along the way, you see a grain of sand, a skin cell and many other tiny things. This is the first time I've ever had a sense of these objects' sizes. Cells are actually bigger than I thought they were. I wish the zoomer would keep going. I want to see some sub-atomic particles on the scale.

"Research has shown that numerous psychological interventions are efficacious, effective, and cost-effective. However, these interventions are used infrequently with patients who would benefit from them, in part because clinical psychologists have not made a convincing case for the use of these interventions ... and because clinical psychologists do not themselves use these interventions even when given the opportunity to do so." In Psychological Science in the Public Interest, psychologists Timothy Baker, Richard McFall, and Varda Shoham argue that clinical psychology needs to embrace its status as a science in order to save itself as a profession. If that's too long, Walter Mischel -- yes, the marshmallow guy -- writes an accompanying editorial. : "The disconnect between much of clinical practice and the advances in psychological science is an unconscionable embarrassment..."

"Common images are bearded, goblin-like demons laughing or whispering sinister speech, a faceless girl (usually covering her face with hair, moving around in bed moaning and feeling my body), hands appearing from the wall and attempting to strangle me. A hung man talking in the corner of the room, and some of the most bizarre experiences may include up to a dozen 'critter' entities (think Gremlins movie) laughing and talking about me. The environment tends to feel like a holographic dollhouse, the experience peaks and then the hallucinations mysteriously vanish when I regain control of my body."- The bizarre world of sleep paralysis, a form of hypnagogia and root of many folkloric figures such as succubi or incubi and the night hag.

What can we learn from quadrapeds about our own bipedal gait?

The Home Office, the UK government department responsible for immigration control, has initiated a program to test the DNA from of potential asylum seekers in an attempt to confirm their true nationalities. The initial program is a six-month pilot limited to claimants arriving from the Horn of Africa. The program, currently using forensic samples provided on a voluntary basis, could potentially expand to other nationalities if successful. The Home Office spokeswoman said ancestral DNA testing would not be used alone but would be combined with language analysis, investigative interviewing techniques and other recognized forensic disciplines, but many are decrying the "deeply flawed" program, from refugee support groups to scientists in the genetic forensics fields (via).

Functional MRI (fMRI) is a widely used technique of brain imaging in the cognitive sciences, allowing researchers to visualize what part of the brain is responding to certain stimuli, resulting in striking images of live brains. These days, fMRI is seeing more non-research use, such as forming the basis of controversial new lie detectors. Craig Bennett, a postdoctoral researcher at UCSB, submitted a whole Atlantic salmon to fMRI analysis, and found that this fish could apparently detect, and respond to, the the emotional state of human beings (poster). Remarkable science, especially considering the salmon was dead at the time. [more inside]

The amazing story of the coelacanth is one of the wonders of the living world that inspires marine biologists such myself. Coelacanths, part of the offshoot lineage of fishes known as "lobed finned ", are very different from typical "ray finned" fishes that you usually think of. Their bizarre lobed fins are thought to be an intermediate step between fish fins and amphibian legs. Scientists had known that these weird fish existed because of fossils for over a century, but we believed that they went extinct 65 million years ago... until a South African fisherman caught one in 1938.

Most people have heard about how rising CO2 levels are resulting in a changing global climate. Fewer have heard about the other consequence of rising CO2 levels- when the CO2 is absorbed into the oceans, it disassociates into carbonic acid. This alters the pH of our world's oceans, and it's called "Ocean Acidification". This changing ocean chemistry has many important and devastating consequences. [more inside]
