“Bill Cosby is back in the headlines this week after
the Associated Pressmade public
a 2005 court deposition in which he admitted to obtaining drugs to give to a woman
in order to “have sex with,” or rape, her. It’s the first such admission
we’ve heard from the now-disgraced comedian amid the dozens of women who came forward
to publicly accuse Cosby of drugging and raping them on occasions that date back
to the 1960s.
But the news is also proof of another truism about
how our culture deals with women who say that they’ve been sexually assaulted.
Even after a few women stepped forward to bring Cosby’s
actions to light, it took two men to raise concern and then verify the stories of
nearly 40 female accusers. The first was comedian Hannibal Buress, whose November
stand-up set about the accusations
against Cosby went viral. The second was Cosby himself, whose lawyers fought bitterly
for months to keep the decade-old deposition from going public.
Every 107 seconds, a sexual assault takes place in
the United States. The vast majority of those assaults — 68% — are never reported
to police, according to the Rape, Abuse
and Incest National Network. Most of those assaults are committed by a friend or
acquaintance of the survivor, not some stranger popping out of the bushes and following
them home late at night.
It’s very rare for someone to lie about being raped.
In fact, according
to the Huffington Post, it’s more likely that someone will commit insurance
fraud than lie about being raped; most studies put false rape reports at about 7%.
Still, when close to 40 women came forward and accused one of Hollywood’s most beloved
stars of rape, they were met with skepticism. Cosby, on the other hand, was cheered
by fans and defended
by colleagues and family members.” Jamilah King, Mic.com
This amazing crystal of pure gold was grown through vapor deposition and is only 10mm high.
I had to use my microscope to make this detailed photo, using 75 individual photos and putting them together with focus stacking.
It really is this bright and shiny!
These silver crystals were electrochemically grown from a solution of silver nitrate, using silver electrodes.
The field of view is 18 mm and is composed of 92 individual photos, combined using focus stacking.
This dendritic structure of pure copper was grown during the copper plating or electro plating of various objects.
The field of view is about 3 cm high.
Magnesium Crystal Cluster Close-up:
This is a close-up of a synthetic magnesium crystal cluster. It was done by distilling magnesium and the group is about 3 cm wide. It is part of my personal collection of elements.
These are beautiful! I love looking at these structures, the colors are so captivating and the structures and quite marvelous.
The copper structure looks like a volcanic eruption of some sort, and I just thought of what it would be like to see these crystal formations on a larger scale. Nonetheless, they are still magnificent in their uniqueness and originality.
Sublimation is a transition directly from a solid phase to a gaseous one. Given typical Earth atmospheric conditions, one of the most commonly observed examples of sublimation is that of solid carbon dioxide, a.k.a. dry ice. Submerging dry ice in water both speeds up the sublimation–since water is a better conductor of heat than air–and creates ethereal fog that’s a combination of the expanding carbon dioxide and condensate from the water. This gorgeous video from Wryfield Lab lets you admire the process close-up. As the dry ice sublimates, watch for the ice crystals that grow on its surface. This is deposition–the opposite of sublimation–and comes from water vapor freezing onto the dry ice. (Video credit: Wryfield Lab; via Gizmodo)
A warning for those who want to try this at home: only do this in well-ventilated spaces. The shift from solid to gas requires a huge increase in volume. Carbon dioxide is denser than air, so it does stay low to the ground, but you can still suffocate yourself (or children or pets) if you do this in an enclosed space.
Wilson’s disease is an uncommon autosomal recessive inherited disorder of copper metabolism. It is characterized by excessive deposition of copper in the liver, brain, and other tissues. The major physiologic abnormality is an excessive absorption of copper from the small intestine and decreased excretion of copper from the liver. Among many signs and symptoms, the deposition of copper can be observed as a ring around the iris under a slit-lamp eye examination.
Dunes are a fascinating interplay between fluid and granular flow. This satellite photo shows a dune field on Mars, Nili Patera. The dominant direction of wind flow is from the upper right, pushing the dunes themselves slowly toward the left. Many of the dunes along the edge are barchans, crescent-shaped dunes with a long, gradual slope facing the wind and a steeper leeward side. As the wind blows, it erodes the sand on the windward slope and deposits it on the leeward side. This is how the dune migrates. Check out this close-up of a barchan to see the changes in its ripples and shape over the past couple months. (Photo credit: NASA/JPL/Univ. of Arizona)
