Crystals And Catalysts

Everyone starts their day with a caffeinated drink, mainly coffee or tea. And everyone believes that coffee is the sole reason why they wake up in the morning.  But did you know that you might be drinking coffee the wrong way? And you might not get all of coffee's benefits ? ASAPScience gives all the details in the video below. 

Fact: The radioactive potassium-40 emits about 15 articles of antimatter a day. So what, exactly, is antimatter? Antimatter is matter consisting of elementary particles which are the antiparticles of those making up normal matter. The person who discovered antimatter was the English Physicist Paul Dirac (1902-1984). Dirac derived an equation that explains how really small and really fast things behave, such as electrons travelling near the speed of light. Later, Dirac realised that not only did his equation & theory discover the behaviour of very tiny things, he also discovered something new to the growing world of science; anti-particles. Paul Dirac continued to assert that every particle has a mirror-image particle with nearly identical properties, except for an opposite electrical charge.  Similar to the way protons, neutrons and electrons combine to form atoms and matter, antiprotons, antineutrons and anti-electrons (called positrons) combine to form anti-atoms an...

Vitamin D refers to a group of fat-soluble secosteroids (a subclass of steroids that consist of “broken” ring structures) that are responsible for the intestinal absorption of calcium, iron, magnesium, phosphate and zinc. The major natural source of the vitamin is in the skin. For vitamin D to be activated from cholesterol (via the skin) it requires sunlight to initiate the activation (especially UVB radiation); you can also obtain vitamin D from food, such as oily fish (salmon, sardines, cod liver oil etc...) and some fortified foods. Vitamin D has been shown to boost bone health and it may play a role in preventing diabetes, cancer, cardiovascular disease and other illnesses. Vitamin D deficiency can occur if: the body has an increased need for vitamin D, the body is unable to produce enough vitamin D, or not enough vitamin D is being taken into the diet. Vitamin D deficiency is more common than vitamin D toxicity. High doses of vitamin D... A study conducted from 2002-201...

***********UPDATED*********** 29/05/2015 The 30 Day Science Blog Challenge will commence on the 1st of June 2015. 30 Days. 30 Topics. A challenge in a month. ______________________________________________________________________________ As many of you have seen, I was starting the 30 Day Science Blogging Challenge and I had hoped I would be able to post for 30 consecutive days during May 2015. However due to unforeseen circumstances and technical difficulties I am not able to keep up with the daily posting so I have postponed the challenge till June 2015. Sorry if this disappoints anyone. I am also thinking of trying to find a better theme/template for my blog with a better user interface. Your thoughts about the current theme would be appreciated!

A promising cure has been found which uses an anti-cancer drug along with an anti-viral drug to treat hepatitis b, and within phase 1/2a trials and has achieved 100% success. Hepatitis-B is a chronic viral disease that is currently incurable.  Over two billion people worldwide are infected with hepatitis B and approximately 400 million have a chronic HBV infection, unimaginable numbers. The virus infects liver cells and can lead to complications including cirrhosis and liver cancer, resulting in more than 780,000 deaths annually. Hepatitis B patients in Australia are the first people who will have access to the potential treatment. The scientists from Melbourne's Walter and Eliza Hall Institute researched the combination of the anti-viral drug and the anti-cancer drug (developed by a US company-TetraLogic pharmaceuticals). Dr Marc Pellegrini and Dr Greg Ebert and their colleagues at the i...

Even though there are thousands of studies proving the efficiency of vaccines and that there is n o association found between MMR vaccine and autism, even among children at higher risk there are still people who believe in anti-vaccination and they are currently putting everyone's lives at risk.  This humerous video shows you how anti-vaxxers sound to normal people (pro-vaxxers). 

This weeks #SOTW is  Elsie Widdowson CBE CH FRS . The well-known British chemist and dietitian. Famous for her research on food composition tables and setting the limits of dietary intake of food, vitamins & minerals in World War 1. Biography  Elsie was born in Surrey, United Kingdom. Her schooldays were spent in south east London where her favourite subject was Zoology. But she had a dedicated chemistry teacher how encouraged her to study chemistry at university instead.   Elsie studied chemistry at Imperial College London and graduated in 1928. She was one of the first females to graduate with a Bachelors of Science from Imperial College (there were only 3 women in her year of a group of 100 students). Elsie took her final exam after only 2 years of studying however had to continue at university for another year before her degree was awarded. In her final year, she spent time in the biochemistry lab presided over by Prof. Samm...

The debate around vaccines has seen a surge in recent years, with many choosing not to vaccinate their children as a result. While anti-vaxxers might not be breaking any laws, those for vaccination have pointed out that they’re putting their own kids at risk and those around them. Why wouldn’t you vaccinate your kids? There’s always been a resistance to vaccines, with numerous studies being done to find a link between inoculation and debilitating conditions such as autism. Anti-vaxxers have used research such as one published in the Journal of Inorganic Biochemistry to link vaccinations to hepatitis B, among others. As a result, a growing number of parents have taken a stance against immunization in fear of the supposed dangers the treatment presents to their children. Although the findings of such research has been inconclusive, it hasn’t deterred anti-vaxxers from their staunch opposition to the treatment. In fact, many influential people such as Jenny McCarthy, ...

(Image: Aldo Sperber/picturetank - from  New Scientist  ) Thirty per cent of the adult population experience seasonal allergies, especially hay fever. The eyes start watering and reddening and noses start running, making you looking and feeling like a big mess. But did you know that these are not the only effects of allergies? Did you know that it affects your brains reaction time to driving too? Hay fever or allergic rhinitis can be aggravated by anything from pollen, mould, dust, fungal spores or animal dander; they aggravate the immune system inappropriately to harmless substances / allergens.  False Alarms... When a pollen grain lands on the damp lining of the nose and throat, its tough outer coat can burst, releasing its contents, including allergenic proteins. These come into contact with immune cells called mast cells, which are the body's first line of defence against invaders.  In most people, these harmless proteins are ignore...

Stem cells are the clean slates of the human body. They're the cells (usually found in bone marrow) that are stored till they have a significant job. Stem cells remain stem cells until they need to differentiate into a specific type of cell i.e  a heart cell, a kidney cell or even a skin cell. New research goes into the way stem cells differentiate and what goes into the process. The study (conducted by the Institute of Biotechnology and Massachusetts Institute of Technology (MIT)) suggests that asymmetric apportioning of old cellular components during cell division may represent an anti-aging mechanism utilized by stem cells. They focus on tissue stem cells, that continuously renew our tissues which divide asymmetrically to produce 2 types of daughter cells: one a new stem cell, the second one will become the differentiating cell of a tissue. Stem cells undergo this technique to prevent cellular damage. Extra damage can cause stem cell fatigue and less tissue regeneration an...
