This snowflake scientist ruins winter for everyone. ❄️ 🔬
We’ve all heard that each and every snowflake is unique. But in a lab in sunny southern California, a physicist has learned to control the way snowflakes grow. Can he really make twins?

For decades, Dr. Howard Markel has taught Fitzgerald’s life and works to his students with the express purpose of using his life to demonstrate how deadly the diseases of alcoholism and addiction can be. Fitzgerald drank and smoked himself into a terminal spiral of cardiomyopathy, coronary artery disease, angina, dyspnea, and syncopal spells.
More than once, friends suggested that Fitzgerald join Alcoholics Anonymous, which was founded in 1935. His response was both contemptuous and, ultimately, self-defeating:
I was never a joiner. AA can only help weak people because their ego is strengthened by the group. The group offers them the strength they lack on their own.
Instead, he chose to go it by himself, hoping that willpower alone would free him of his addiction - but the binges never really stopped.

INDEPENDENT LENS: SEED: The Untold StoryIn the last century, 94% of our seed varieties have disappeared. This once abundant seed diversity — painstakingly created by ancient farmers and gardeners over countless millennia — has been drastically winnowed down to a handful of mass-produced varieties. Under the spell of industrial “progress” and corporate profits, family farmsteads have given way to mechanized agribusinesses sowing genetically identical crops on a massive scale. But without seed diversity, crop diseases rise and empires fall. Stream the film
“COLLISION WITH ICEBERG - Apr 14…the British steamer TITANIC collided with an iceberg seriously damaging her bow; extent not definitively known”
Daily Memorandum from the Hydrographic Office Reporting Titanic Disaster, 4/15/1912
File Unit: In the Matter of the Petition of the Oceanic Steam Navigation Company, Limited, for Limitation of its Liability as owner of the steamship TITANIC, 10/14/1912 - 5/23/1918. Series: Admiralty Case Files, 1790 - 1966. Record Group 21: Records of District Courts of the United States, 1685 - 2009
105 years ago on the evening of April 14, 1912, the passenger liner RMS Titanic struck an iceberg and sank in the North Atlantic, taking over 1,500 lives. This memorandum from the Hydrographic Office is among the many documents in the Admiralty Case Files pertaining to the Titanic sinking.
Our colleagues from the National Archives at New York earlier shared some of their favorite records from admiralty case files related to Titanic. Among the documents are depositions of surviving passengers, blueprints of the ship, claims of loss and photographs. Often in the first person, they tell the story of the sinking in dramatic detail:(video)
The stories of the survivors and those who were lost are now being told in a new exhibit, “Titanic at the Ronald Reagan Presidential Library,” opening on May 27, 2017: https://reaganlibrary.gov/coming-soon

This is a process in which water seeps out at the tips or edges of a plant’s leaves. The water is from xylem — the main water transport tissue in a plant. Usually, extra water escapes through tiny holes in the plant’s leaves and stem called stomata. But sometimes, those stomata are closed. When that happens, the pressure from water entering the roots continues to force water up through the plant. The water — and nutrients it picks up on the way — forces its way out as droplets at the tips and edges of leaves.

On 14 April 1912, the Virginian recorded the last known signals from the sinking Titanic. The Virginian was too far away to assist in the rescue; however this procès-verbal, usually a summary of wireless messages but in this case whole messages, adds to the picture of the final moments of the Titanic. Messages sent via wireless telegraphy used Morse code, and for brevity the Titanic was represented by ‘MGY’, the Virginian ‘MGN’, and the Olympic ‘MKC’. After a gap in communications, the operator was able to recognise two ‘Vs’ sent with a spark like the Titanic operator’s, then a faint ‘CQ’ call before power appeared to be abruptly cut off. This probably marks the final loss of power to the wireless equipment on the stricken ship.
The item is currently on display in our Treasures exhibition until February 2018: https://treasures.bodleian.ox.ac.uk/treasures/proces-verbal.

From the bottom of the deepest glacial fjord to the summit of its highest peak, Glacier Bay National Park encompasses some of our continent’s most amazing scenery and wildness. If we need a place to intrigue and inspire us, this is it. Alaska’s Glacier Bay is a living laboratory, a designated wilderness, a biosphere reserve and a world heritage site. It’s a marine park, where great adventure awaits by boating into inlets, coves and close to its dynamic, namesake glacier. It’s also a land park, with its snow-capped mountains, spectacular glaciers and vast forests. Photo by National Park Service.
