I Struggle To Understand Why Other White People Refuse To Realise They're Racist. You Can Be At Every

You can learn more about the surprisingly long history of the SR-71 over at Gizmodo.

u know what … i changed my mind… all u scientists out there who worked ur butts off just to have your research purposefully ignored by the government… do your science thing and bring back the dinosaurs… catch them ignoring you when a velociraptor is our next president…. like ding dong what’s that? it’s science, it doesn’t care about your silly ignorant opinion… it’s back with a vengeance… and it’s hungry, bitch

The essence of life is not the atoms and small molecules that go into us, it’s the way, the ordering, that those molecules are put together.

Chameleon colours ‘switched by crystals’:

Swiss researchers have discovered how chameleons accomplish their vivid colour changes: they rearrange the crystals inside specialised skin cells.

It was previously suggested that the reptiles’ famous ability came from gathering or dispersing coloured pigments inside different cells. But the new results put it down to a “selective mirror” made of crystals. They also reveal a second layer of the cells that reflect near-infrared light and might help the animals keep cool. Reptiles make colours in two ways: they have cells full of pigment for warm or dark colours, but brighter blues and whites come from light bouncing off physical elements like these crystals: so-called “structural colours”. These colours can also be mixed. A vibrant green might arise from a structural blue overlaid by yellow pigment.

Alzheimer's Disease linked to the metabolism of unsaturated fats

A new study published in PLOS Medicine’s Special Issue on Dementia has found that the metabolism of omega-3 and omega-6 unsaturated fatty acids in the brain are associated with the progression of Alzheimer’s disease.

Alzheimer’s disease is a neurodegenerative disorder, which causes impaired memory, executive function and language. It accounts for 60 - 80% of total dementia cases worldwide, with over 46 million people suffering from the disease worldwide. The number of patients is estimated to rise to 131.5 million by 2050.

Currently it is thought that the main reason for developing memory problems in dementia is the presence of two big molecules in the brain called tau and amyloid proteins. These proteins have been extensively studied and have been shown to start accumulating in the brain up to 20 years prior to the onset of the disease. However, there is limited information on how small molecule metabolism in the brain is associated with the development and progression of Alzheimer’s disease.

In this study, researchers from King’s College London and the National Institute on Aging in the United States looked at brain tissue samples from 43 people ranging in age from 57 to 95 years old. They compared the differences in hundreds of small molecules in three groups: 14 people with healthy brains, 15 that had high levels of tau and amyloid but didn’t show memory problems and 14 clinically diagnosed Alzheimer’s patients.

They also looked at three different areas in the brain, one that usually shows little tau and amyloid, one that shows more tau and another that shows more amyloid. The main molecules that were different were six small fats, including omegas, which changed in abundance in different regions of the brain.

They found that unsaturated fatty acids were significantly decreased in Alzheimer’s brains when compared to brains from healthy patients.

Co-lead author of the study, Dr Cristina Legido Quigley from King’s College London said: “While this was a small study, our results show a potentially crucial and unexpected role for fats in the onset of dementia. Most surprisingly we found that a supposedly beneficial omega3, DHA, actually increased with the progression of the disease.

“It is now important for us to build on and replicate these findings in a larger study and see whether it corroborates our initial findings.”

In early 1971, Kay Brown, Dindga McCannon, and Faith Ringgold gathered a group of black women at McCannon’s Brooklyn home to discuss their common frustrations in trying to build their careers as artists. Excluded from the largely white downtown art world, as well as from the male-dominated black art world, the women found juggling their creative ambitions with their roles as mothers and working heads of households left little time to make and promote their art.

Out of this initial gathering came one of the first exhibitions of professional black women artists. “Where We At”—Black Women Artists, 1971, opened at Acts of Art Gallery in the West Village that June. Adopting the show’s title as their name, the collective began meeting at members’ homes and studios, building support systems for making their work, while assisting each other with personal matters such as childcare.

Influenced by the Black Arts Movement, members worked largely in figurative styles, emphasizing black subjects. While the group engaged politically with racism, their work also spoke to personal experiences of sexism, and members contributed to publications including the Feminist Art Journal and Heresies. Though the group’s mission was not explicitly feminist, Where We At recognized the power of collectivity—empowering black women by creating a network to help attain their professional goals as artists.

“This is a reminder of what we can do when we look out for one another. Like Joe Biden and so many other Americans, I’ve lost people I love deeply to cancer. I’ve heard often from those whose loved ones are suffering from Alzheimer’s, addiction, and other debilitating diseases. Their heartbreak is real, and so we have a responsibility to respond with real solutions. This bill will make a big difference, and I look forward to signing it as soon as it reaches my desk.” —President Obama on the passage of the bipartisan 21st Century Cures Act, which includes $1.8 billion dollars for Vice President Biden’s Cancer Moonshot initiative to end cancer as we know it

Brexit 'will enhance' UK wildlife laws - Gove - BBC News

Any Brexit changes to the UK's wildlife laws will increase - not reduce - environmental protection, Michael Gove has pledged.
