Time is essential for the human mind and for anyone's flow of ideas. Consequently you'll find in the mesmerizing grid and flow of time the sparkles and the flashes of what makes us human and thus unique.
A recent study in Science reported that some of the world’s oldest trees—most between 100 to 300 years old—are dying rapidly, in part because of climate change. This infographic (from 2010, but still relevant) shows the location of trees that are even older, and now at risk.
Want to hear more about really really old trees? We’ve got a story for you.
Ice Caves Around the World
Ice caves come in two forms. A cave formed entirely of ice is actually called a glacier cave and as the name implies, forms in glaciers. Water runs through or under the glacier and forms a cave.
The other type of ice cave can be any cave type (limestone, lava tube, etc.) that has ice in it year round. These caves trap cold air. Water entering the cave freezes and stays frozen year round.
Glacier caves can be found in the Pacific Northwest and ice caves are found in many locations where temperatures drop below freezing. Once cold air enters the cave, it generally stays there.
Spectrum of Colors Revealed Through Lit String
British artist, physicist, and all-around science enthusiast Paul Friedlander produces kinetic light sculptures that provide a colorful feast for the eyes. Each piece in his body of work offers a visual medley of light and motion by rapidly rotating a piece of string through white light. The vibrating rope becomes invisible to the human eye, but colors from the light (which would normally be invisible to the naked eye) are revealed in rapid succession.
The scientific artist gives insight into the history of his career shift into the arts and explains the science in it all: “I decided to focus on kinetic art: a subject in which I could bring together my divided background and combine my knowledge of physics with my love of light. In 1983, at London’s ICA, I exhibited the first sculptures to use chromastrobic light, a discovery I had made the previous year. Chromastrobic light changes color faster than the eye can see, causing the appearance of rapidly moving forms to mutate in the most remarkable ways.”
Day #7 A Flock of Fluoroquinolines (-floxacins)
The fluoroquinolones are a group of bacteriocidal antibiotics that interfere with bacteria’s DNA replication. This group covers gram negative, positive, and intracellular organisms. Ciprofloxacin, ofloxacin, and levofloxacin are a few examples. Side effects include long QT syndrome and tendon rupture.
Day #13 Myasthenia Gravis
Myasthenia Gravis is an autoimmune disorder against post synaptic acetylcholine receptors. Most often affects young, adult, females and is associated with thymomas. Symptoms include proximal weakness and ptosis. Symptoms worsen as the day progresses and EMG shows a decremental response to repetitive nerve stimulation. Treatment includes pyridostigmine.
Happy 72nd Birthday Richard!! Wishing you many, many more. After losing Hitch at such a young age, I couldn’t bare losing him any time soon. Aside from being an outspoken advocate of atheism and Science, he is a brilliant individual. I’m proud to have someone like him on my side.
