The Curiosity rover recently drove over a rock, accidentally cracking it open. Inside were shiny yellow crystals, which scientists later determined to be elemental sulfur, NASA said. Although sulfur-based minerals a mix of sulfur with other materials have been found on Mars before, this is the first discovery of rocks made of pure sulfur. And there could be a whole bunch of them on Mars, but scientists aren ;t sure how they formed. Credit: NASA/JPL-Caltech/MSSS Finding a field of stones made of pure sulfur is like finding an oasis in the desert, Ashwin Vasavada, Curiositys project scientist at NASAs Jet Propulsion Laboratory, said in a statement. It shouldnt be there, so now we have to explain it. Pure sulfur is tasteless and odorless, and it naturally

stanley cup becher g has shown no signs of past volcanic activity. Pure sulfur can also form through the oxidation of reduced sulfur compounds by way of microbial activity. In that case, the discovery of sulfur on Mars could be useful in the search for ancient microbial life on the Red Planet. The Curiosity rover ca

My physio, a young woman called Lucy, was simply making conversation. She wanted to distract me from
stanley thermos the serious discomfort she was about to inflict by massaging the nerves around my painful posterior tibial tendon, an ankle injury I assumed I had brought on by running too much. My mothers post tib has ruptured, she said. Its really common in menopausal women. This definitely worked as a distraction. What did all this have to do with the menopause, I asked She looked surprised, because to her the answer was obvious: Collagen. Suddenly something clicked, and not just in my ankle. For about a year, the
Stanley cup website skin on my hands had been peeling, monthly. Id seen GPs and pharmacists and been given various remedies, from try thick hand cream to drink more water . Lucys comment made me research more: oestrogen is related to collagen production, and when oestrogen levels start to change in women who are in the stage approaching the menopause the so-called perimenopause , all sorts can happen. Perhaps I should have known this. Ive already had one menopause. It was chemically induced as a treatment for my endometriosis, a condition where the cells that line the i

Leuprorelin is not fussy: it can block testosterone in men and oestrogen in women, hence its used to treat prostate cancer and chemically castrate paedophil
