Rare Nacreous Clouds
Also called polar stratospheric clouds or mother of pearl clouds, nacreous clouds are mostly visible within two hours after sunset or before dawn. They blaze unbelievably bright with vivid, iridescent colors. These clouds are rare and occur in the polar stratosphere at altitudes of 15,000–25,000 meters. They are so bright because at those heights, they are still sunlit.
Although incredibly beautiful, they have a negative impact on our atmosphere. They create ozone holes by supporting chemical reactions that produce active chlorine which catalyzes ozone destruction.
HOW TO SURVIVE A HEART ATTACK WHEN ALONE
Let’s say it’s 6.15pm and you’re going home (alone of course), after an unusually hard day on the job. You’re really tired, upset and frustrated. Suddenly you start experiencing severe pain in your chest that starts to drag out into your arm and up into your jaw. You are only about five miles from the hospital nearest your home. Unfortunately you don’t know if you’ll be able to make it that far. You have been trained in CPR, but the guy that taught the course did not tell you how to perform it on yourself..!!
NOW HOW TO SURVIVE A HEART ATTACK WHEN ALONE…
Since many people are alone when they suffer a heart attack, without help, the person whose heart is beating improperly and who begins to feel faint, has only about 10 seconds left before losing consciousness.
However, these victims can help themselves by coughing repeatedly and very vigorously.
A deep breath should be taken before each cough, and the cough must be deep and prolonged, as when producing sputum from deep inside the chest.
A breath and a cough must be repeated about every two seconds without let-up until help arrives, or until the heart is felt to be beating normally again.
Deep breaths get oxygen into the lungs and coughing movements squeeze the heart and keep the blood circulating.
The squeezing pressure on the heart also helps it regain normal rhythm. In this way, heart attack victims can perhaps buy precious time to get themselves to a phone and dial 911.

What happens inside a pupa stays inside a pupa. Or it used to, anyway. Until recently, when special x-ray imagers were turned on a developing butterfly to elucidate its metamorphosis.
the process of caterpillar-to-butterfly is a messy one. An overfed worm not only has to convert a lot of the stored energy it gathered stuffing its face for a few weeks into new body parts, it does so by essentially dissolving much of its body and reforming. The pupa isn’t so much a dressing room for a beautiful diva as it is a bag to keep all the goopy globs of proto-butterfly from dripping on the ground. Sounds like both butterfly and human puberty involve a mess of bodily fluids and hiding in your room.
That’s what most biology books would have you believe anyway. This new work (written up in great detail by Ed Yong) demonstrates that while there’s still plenty of goop-globbing, quite a few structures remain intact, migrating and growing into adult forms in a more traditional way (like those blue circulation vessels). For the insect nerds in the bunch, this technique doesn’t revolutionize metamorphosis or anything, but it’s a view inside that most of us have never gotten.
And quite a view it is.
