Scientists claim to diagnose football-related brain injury in living patients for first time

For the first time, scientists have confirmed a diagnosis of chronic traumatic encephalopathy (CTE) — a neurological disease linked to head injuries from sports like football — in a living person. Until now, we’ve only been able to diagnose CTE in dead patients. Finding the disease while the patient is still alive could help scientists find a way to treat it. CTE develops from repeated hits to the head and has been linked to severe memory loss, depression, and dementia. It’s been found in 99 percent of the donated brains of NFL players. In a study published in the journal Neurosurgery, researchers found a telltale sign of CTE, a specific protein, in the brains of 14 retired NFL players who underwent a brain scan. Now that one of the players has died and doctors have been able to take a closer look at his brain, they have confirmed the CTE diagnosis. Many former National Football League players like Aaron Hernandez and Junior Seau have been found to have the progressive brain disease. Last year, the NFL reached a billion-dollar settlement, the largest in sports history, over a lawsuit from former players who suffered concussions and now have severe neurological diseases like amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease). The subject of the paper was former NFL player Fred McNeill, according to CNN. McNeill played 12 seasons in the National Football League for the Minnesota Vikings, reporting one concussion. But by the time he was 59, McNeill was already experiencing serious problems with his motor skills, and so he sat for the brain scan. Scientists found increased levels of certain proteins in his brain, including the tau protein, which has been linked to Alzheimer’s. After McNeill died two years ago, at 63, detailed brain-tissue analysis confirmed that his brain had other physical signs of CTE, suggesting that the tau protein is linked to the disease. A study from September suggested that the levels of another protein, called CCL11, may also be used to diagnose CTE in living patients.

History will judge Trump, and it will not be kind.

I spoke with [historian Robert] Dallek about the history of corruption in American presidential politics and why he sees the Trump administration as “a low point in our history.” What makes Trump exceptionally dangerous, Dallek argues, is how effortlessly he lies and what kind of tone he has set in this White House.

Researchers Discover the Brain is Strobing, Not Constant

It’s not just our eyes that play tricks on us, but our ears. That’s the finding of a landmark Australian-led collaboration that provides new evidence that oscillations, or ‘strobes’, are a general feature of human perception.

The research is in Current Biology. (full access paywall)

Light Echoes From Supernova 2014J

In the image below, we can see light from a supernova explosion in the nearby starburst galaxy M82 that is reverberating off a huge dust cloud in interstellar space.

The supernova, called SN 2014J, occurred at the upper right of the nearby galaxy M82, and is marked by an “X.”
The inset images at top reveal an expanding shell of light from the stellar explosion sweeping through interstellar space, called a “light echo”.
The images were taken 10 months to nearly two years after the violent event (Nov. 6, 2014 to Oct. 12, 2016). The light is bouncing off a giant dust cloud that extends 300 to 1,600 light-years from the supernova and is being reflected toward Earth.
The M82 image, located about 11 million light-years away and appearing high in the constellation Ursa Major, was taken in 2006 by the Hubble Space Telescope's Advanced Camera for Surveys. The inset images of the light echo also were taken by the Advanced Camera for Surveys

But let's try to understand what a light echo really is and when occurs!

In short, a light echo is a physical phenomenon caused by light reflected off surfaces distant from the source, and arriving at the observer with a delay relative to this distance. The phenomenon is analogous to an echo of sound, but due to the much faster speed of light, it mostly only manifests itself over astronomical distances.

SN 2014J was discovered by astronomer Steve Fossey, of University College London in mid-January 2014, during an undergraduate teaching session at University of London Observatory. The discovery was serendipitous, as it can happen, and was reported to the International Astronomical Union's Central Bureau for Astronomical Telegrams, who confirmed that they (Fossey and four undergraduate students: Ben Cooke, Guy Pollack, Matthew Wilde and Thomas Wrightwere) were the first to spot the supernova and assigned it the name SN 2014J as the tenth supernova discovered in 2014 (see the discovery press release>> http://www.ucl.ac.uk/mathematical-physical-sciences/news-events/maps-news-publication/maps1405).

At a distance of 11.5 ± 0.8 million light-years, SN 2014J was one of the closest supernovae seen for decades. It was the closest type Ia supernova since SN 1972E, and the closest supernova of any type since 2004.
Type Ia supernovas are used as cosmic distance-markers and played a key role in the discovery of the Universe’s accelerated expansion, which has been attributed to the effects of dark energy. Scientists think that all Type Ia supernovas involve the detonation of a white dwarf. One important question is whether the fuse on the explosion is lit when the white dwarf pulls too much material from a companion star like the Sun, or when two white dwarf stars merge.
Its unusual brightness and relative closeness led to SN 2014J becoming the subject of intense follow-up observations by astronomers worldwide, including with the Hubble Space Telescope.
Over a hundred scientific papers have discussed the supernova (SN 2014J bibliography: http://simbad.u-strasbg.fr/simbad/sim-id?Ident=sn+2014J&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id#lab_bib).

Manetti Shrem Museum of Art (University of California – Davis, California)

The Canopy - Version 1 (© Alex James Photos 2017)

This is simply amazing architecture. I will admit that I was giddy, to say the least, standing there, whirling around, gathering my thoughts. The angles were endless. The composition choices mind boggling. Back in August, on a whim, hubby, +Steve Alfano and I took a quick turn off the freeway and made our way to this work of art. I am so glad we did and absolutely can’t wait to return there again at a more leisurely pace.

This 50,000-square foot canopy of aluminum and steel covers the museum site and was specially designed to catch light and shadows in a variety of ways, most significantly, through the airy, perforated design of the canopy and supporting structures. The shadows created by this porous beauty reflect everywhere and gracefully move throughout the day as the sun changes its location.

In this image, I am focusing in on the fabulous lines and curves of the structure, looking up toward the sky. The light streams through the perforations, accenting every beautiful nook and cranny … more images to come … this one deserves a small series, at least!

Confusion

Spreading cotoneaster (Cotoneaster divaricatus)

Svartskog, Norway

Of all the specimens in their autumn colors and full of small red berries, one was very confused as it was dotted with flower buds and open flowers!

What made this specific plant decide to produce flowers now? What is so different with this particular plant? It is growing with many of its kind right next to it, but has a very different response to the autumn.

Yet it is not as uncommon as one might think – at least with some species! Every autumn I find honeysuckles producing flowers, and the harebell also with flowers and buds, but I don’t remember if it was like this when I was a kid.

A 30 second long exposure of the waves crashing on the rocks of Playa Maderas in southern Nicaragua. A picturesque beach with interesting cliff formations and waves all day long for those surfers out there…

For those wondering, that 'misty' effect of the water is from a long shutter speed as the waves crashed over the rocks in the foreground. The shot was taken around about 25 minutes after the sun dipped below the horizon.
