It is everyone’s desire to have beautiful, clear skin but sometimes that’s not always possible. Especially in our teenage years spots start to appear and if you’re really unlucky it turns into acne.  Although acne can take a long time to go away, there are lot of treatments for it available today; and here’s the newest, method of acne treatment & prevention. Pimples form when follicles get blocked by sebum, an oily, waxy substance secreted by sebaceous glands located adjacent to the follicle. Excretion of sebum is a natural process and functions to lubricate and waterproof the skin. Occasionally, however, the openings of the follicles (pores) get blocked, typically by bits of hair, skin, dirt or other debris mixed in with the sebum. Overproduction of sebum is also a problem, which can be caused by hormones or medications. Changes in the skin, such as its thickening during puberty, can also contribute to follicle blockage. Whatever the cause, the accumulating sebum holds ...

Ultraviolet radiation (UVR) is an electromagnetic wave. It comes from the sun and travels to the surface of the Earth. While UVR is vital to human (it provides us with the essential vitamin, vitamin D), but it can also cause harm especially to the eye and skin such as burn, hyperpigmentation, photoaging skin, keratoconjunctivitis, stimulation of photodermatoses and cutaneous cancer. This is why we need different methods of protection from the harmful and potentially damaging sun rays. The types of protection can be split into the two categories: Chemical protection (sunscreen) and Physical protection such as using hats, garments, sunglasses. Umbrellas are also a great method of protection from the sun and one of the ways to protect yourself from UVR due to its convenience, availability as well as its ability to protect one from rain. However, there are only few studies on UVR protection efficacy of different types of umbrellas and no clear conclusions can be drawn...

Biography: Francis Crick born on the 8 th June 1916 in Northampton, United Kingdom, graduated from UCL in 1937. During World War 2 he worked as a scientist for the Admiralty Research Laboratory, working on the design of magnetic and acoustic mines. In 1940 Crick married Ruth Doreen Dodd. Their son, Michael F.C Crick is a scientist. They were divorced in 1947. In 1949 Crick married Odile Speed. They have two daughters, Gabrielle A. Crick and Jacqueline M.T. Crick.  The family lived in a house called the “The Golden Helix” appropriately named by Crick, and it made a good conversation topic with his friends. In 1947 Crick made the transition from physics into biology, which he described as "almost as if one had to be born again." His early studies at Cambridge were supported by a studentship from the Medical Research Council (MRC). In 1949 he joined the MRC Unit headed by Max Perutz, which subsequently became the MRC Laboratory of Molecular Biology. During th...

A new molecule making machine could imitate 3-D printing, making it fast, flexible and accessible to everyone. This machine can assemble small, complex molecules at the click of a mouse. This automated process has the potential to greatly speed up and enable new drug development and other technologies that rely on small molecules. A team of chemists led by Martin D. Burke, at University of Illinois a team led by Martin D. Burke built the machine to imitate 3-D printer at a molecular level. They described the technology in a paper featured on the cover of the March 13 issue of Science. "Small molecules" are a specific class of complex, compact chemical structures found throughout nature. They are very important in medicine -- most medications available now are small molecules -- as well as in biology as probes to uncover the inner workings of cells and tissues. But small molecules are also very difficult to produce in a laboratory, and it takes a highly experienced che...

Back in 1631 the emperor Shah Jahan built the Taj Mahal for his deceased wife, Mumtaz Mahal, to honor her memory . It is regarded as one of the seven wonders of the world. Sadly this wonder is becoming tarnished by the day. Due to pollution, the Taj Mahal marble is starting to turn yellow. Even though, every couple of years the mausoleum is given a clay mask to remove all the grime and restore the sparkling white marble, the grime returns over and over again every few years.

We were always warned at university about the reliability of Wikipedia and that we shouldn't use it for guidance when working on projects and/or coursework and we're recommended to use Google Scholar and Science Direct for scientific research.  Because Wikipedia is an open online encyclopedia in which everyone and anyone can edit and add to the pages, its reliability isn't 100%. However the good news is, is that the Royal Society of Chemistry (RSC) have given access to the chemistry writers at Wikipedia access to their all their journals (gold accounts) so to ensure that every single piece of information on Wikipedia is correct and to update with all the latest updates in chemistry research.  Donating 100 "RSC Gold" accounts to Wikipedia editors gives them access  to the complete portfolio of RSC journals and databases.  Andy Mabbett the RSC's Wikimedian in Residence commented to the Royal Society of Chemistry's bl...

Exam season is always a stressful time for students and every time it comes around everyone prepares in their own to make sure they can perform their best, even if it means taking performance enhancing drugs. There’s a prescription drug called Modafinil that can enhance your concentration. Personally I've never heard of anything like this till yesterday, the only drug I heard of at exam season is caffeine pills. Loads of students would take caffeine pills at exam season to try and stay up and revise or pull an all-nighter the day before the exam to cram in as much information as possible.  But sometimes that didn’t end up well because some students would end up taking too much caffeine pills and faint during the exam and subsequently need to be hospitalised for overdose.

Ozone is typically associated with the ozone layer that surrounds the Earth and any articles about it are usually about the size of the hole in the ozone layer and how and what affects it every day. But that isn't what this article is about. This blog post is about how ozone can be bubbled into water to make nano-bubble water that is a powerful antiseptic agent that can be used to treat periodontitis and other dental related problems. The new research was published in the journal: Science and Technology of advanced materials.

Proposals have surfaced that paracetamol should be reassessed to make a “safer” version of paracetamol without the liver-harming side effects, even though paracetamol is the most widely exploited pain-killer for everyone around the world and a good antipyretic (fever reducer).

Botox is famous for being used for cosmetic reasons and it is largely used an anti-ageing treatment to try and reverse fine lines and wrinkles on the face. It’s also known to get rid of migraines and headaches caused by possible uncontrollable muscle spasm; Botox inhibits muscle spasms and therefore causes muscle paralysis thus relieving the headache/migraine. Although Botox has a reputation for being an “age-defying elixir” it also has medical uses and can be used as a treatment for certain neuromuscular conditions.
