Five chemistry inventions that enabled the modern world

Share 2k shares Fear results is thought it could be controlled by a cluster of neurons that form the PVT, or paraventricular nucleus of something known as the thalamus. This region of the brain is extremely sensitive to stress, acting as a sensor for both psychological and physical tension. Fear will startle you into reacting, which is when the fight or flight response is triggered which causes your adrenal glands to start pumping out adrenaline Fear will startle you into reacting, which is when the fight or flight response is triggered which causes your adrenal glands to start pumping out adrenaline. This raises your heart rate, sharpens senses and provides access to huge amounts of energy in order to cope with threats to survival. At times, the threat is so intense it can cause a ‘freeze’ response. This could be interpreted as the brain being overwhelmed, or it may have evolved as a way of keeping still to hide from predators. If your axe murderer catches up with you, you will likely feel severe pain. Those are collected by the thalamus, which in tries to tell the brain to do whatever it can to stop the injury happening again. According to recent studies, the brain appears to undergo a final surge which can be associated with consciousness.

This timeline charts the development of the business from its first days as a herbalist store in Nottingham in the mid s to its position as a modern global brand. The Thomsonian system of healthcare, first developed in the US, appealed to the devoutly religious John, as it offered a practical approach to enable the poorest to help themselves. Jesse was rewarded with a partnership in the family business, having left school at the age of 13 to give full time support to his mother.

The sale of herbs was a big feature of the early business and included roots, plants, and flowers collected locally, many of them dried on the parlour walls at the back of the shop and then powdered. However as demands from the expanding store network grew, space was found in a factory on Island Street in Nottingham which had excellent rail, road and canal transportation links.

Within just a few years Boots had taken over the entire factory and acquired further properties nearby. They had met the previous year when Jesse took a much-needed holiday to Jersey. Florence, the daughter of a bookseller and stationers, took a keen interest in the business, introducing new product ranges and progressive staff welfare initiatives. The impressive new shop showcased the varied array of products now available at Boots, from the dispensary, perfumery and stationery on the ground floor to the pictures, glass and fancy goods on the upstairs gallery.

Impressed by the latest innovations, such as electric lighting, the store “took the public fancy amazingly”.

That process pumps out adrenaline through the body, and pushes out glucose through the blood stream. Other chemicals keep those processes working. Screams You might not get away from the axe murderer or whoever else is chasing you down. The video points out that process originates in a different part of the brain from language, and serves a different function.

Screams come out almost by instinct.

The Baffert horses died from a variety of ailments, including cardiac arrest, pulmonary hemorrhage, and internal bleeding. The seven corpses were sent to a laboratory that conducts post-mortem examinations and toxicology tests on all deceased horses at California Horse Racing Board licensed facilities. The necropsy program is part of a long-standing CHRB policy. With the exception of trace elements of a rodenticide discovered in one of the Baffert horses, nothing unusual was found in toxicology tests, and CHRB officials have not suggested Baffert, his veterinarians, or staff were doing anything illegal or unethical that led to the deaths of the seven horses.

So the cause of sudden deaths to seven otherwise healthy horses in one barn over a month period will likely remain an unsolved mystery. Cartel Quick was sent to a state lab in Albuquerque, N. In the meantime, Shaun Hubbard, general manager of Ruidoso Downs Racetrack and Casino, said Orozco will not be permitted to race at the New Mexico track until the investigation into Cartel Quick’s death is completed. Orozco has one horse in a Derby Trial this Friday that was entered prior to Sunday’s Ruidoso Futurity and will be allowed to compete.

Orozco will be banned from the facility, Hubbard said, through the track’s private property right of exclusion. Orozco, who according to published reports gave up a career as an attorney in Mexico to train horses, has been leasing stalls at a private facility adjacent to Ruidoso Downs, Hubbard said. Orozco has won with nine of his 26 starters in , according to the American Quarter Horse Association.

Hubbard recognizes Quarter horse racing has been tarnished by illegal drugging and deaths of horses at Ruidoso Downs and other tracks.

There are no grant mechanisms for this sort of thing either – imagine – “I’d like funds to test four compounds as potential inhibitors of snoraze” – no chance at least with the panels I’ve sat on too small, too speculative The bigger problem though is finding someone with the assay or the compounds. But, there’s a lot of people with compounds to test, and a lot of biologists with assays that are easy to run in their labs, and they have expertise in, but who can’t assemble sets of interesting compounds to profile.

Why not just use the paradigm of a dating site to matchmake mutually compatible biologists and chemists – if there is a spark, it could develop into a long lasting collaborative relationship! Biologist with HMGCoA reductase assay and expertise in cholesterol homeostasis would like to meet chemist with non-statin compounds likely to be brain penetrant to test a cool idea.

A Dating Site For Chemists and Biologists Probably everyone who reads the ChEMBL-og will have world-changing ideas – but it’s really difficult to find someone to screen a few compounds for you – of course there are CROs who will want to meet, then prepare a quote for you, set up a CDA, receive payment, etc., but cash is difficult to get hold of, and the process will be slow.

Did the inventor persuade anyone to back him? Steve Snelgrove, Cardiff I seem to remember Watneys had a beer with that name in the late sixties or early seventies. That’s where they got it! Les Stennett, Woodplumpton, Preston If it’s the same product, I recall a documentary about the subject about five years ago – the inventor’s demonstration consisted of painting a raw egg with a thin layer of his compound, letting a blowtorch play over it for ten minutes and then breaking the egg to reveal that it was still raw.

He refused to patent the recipe as that would mean making it public and risking its theft, but equally refused to name a price for the rights to the invention on the rather toght-fisted grounds that his invention was so good that if someone offered him ten million pounds for it, someone else would offer twenty and therefore he’d never be able to get the highest price he could. I hope a few years of getting no money out of it at all may have softened his hard business nose.

Starlite’s properties are so phenomenal yet so little understood, they raise profound uncertainties about future military applications. Be assured that the UK and the US have been putting the stuff through the analytical wringer. A little later that year the whole nation had an opportunity to see for themselves the effectiveness of Maurice Ward’s new paint on BBC Television when it was featured on “Tomorrow’s World”.

Presenter Michael Rodd showed viewers an ordinary chicken’s egg that had been painted with the new coating. The paint was so thin it was not visible. Rodd then dramatically donned welder’s visor and gauntlets, lit up an oxyacetylene torch, and played the flame directly onto the egg for several minutes.

In an organic lab, you mix chemicals together and hope something happens. Ideally, you get a chemical reaction you expect. As a formulating chemist , you mix chemicals together and hope nothing happens. Unfortunately, they often do react or otherwise change so you need to test your formulas to see how long they will last. This is called Stability Testing and is something a cosmetic scientist spend much of her time doing.

Unlike the radioactive isotopes discussed above, these isotopes are constantly being replenished in small amounts in one of two ways. The bottom two entries, uranium and thorium , are replenished as the long-lived uranium atoms decay. These will be discussed in the next section. The other three, Carbon , beryllium , and chlorine are produced by cosmic rays–high energy particles and photons in space–as they hit the Earth’s upper atmosphere.

Search Share Not creepy anymore. A survey of married Americans finds that one third met online and that their marriages do just as well as the marriages of the rest. But how have those marriages fared compared with those of people who met in more traditional venues such as bars or parties? Pretty well, according to a new study. A survey of nearly 20, Americans reveals that marriages between people who met online are at least as stable and satisfying as those who first met in the real world—possibly more so.

When online dating started gaining widespread attention a decade ago, many people considered it creepy. But after the exponential growth of dating websites such as Match and OkCupid, online dating has become a mainstream activity. John Cacioppo, a psychologist at the University of Chicago in Illinois, wondered how online dating has changed American family life. Enough time has passed that millions of Americans who first met online are now married, a population large enough for traditional psychological survey techniques.

Cacioppo is a scientific adviser to eHarmony, one of the largest online dating sites. He convinced the company to pay for an online survey of Americans. Nearly half a million people received an e-mail from uSamp, a company that pays people to take part in surveys. From the nearly , who responded, a population of 19, people were chosen, all of whom got married between and

After all, they have those impossibly long legs, hazel eyes, curves and dark hair that make them look like they dropped right off the screen of some fantasy movie. They look how you expect women to look. Arab women are portrayed in movies as sultry and exotic creatures, with a fiery heart, and that’s not too far from the truth. These ladies are a complex, and intoxicating, mixture of the exotic and sensual, while also being shy, and even innocent.

They’re women from a traditional background who want to enjoy everything a modern relationship has to offer. This is exactly why Arab women are looking for husbands from Europe and the United States.

So the Royal Society of Chemistry decided to look into what people really think of chemistry , chemists and chemicals. Chemistry hall of fame. Penicillin Not a cowshed, but a wartime penicillin production plant. Without it, a prick from a thorn or sore throat can easily turn fatal. Alexander Fleming generally gets the credit for penicillin when, in , he famously observed how a mould growing on his petri dishes suppressed the growth of nearby bacteria.

But, despite his best efforts, he failed to extract any usable penicillin. Fleming gave up and the story of penicillin took a year hiatus. Until in it took Australian pharmacologist Howard Florey and his team of chemists to figure out a way of purifying penicillin in useable quantities. The team therefore cobbled together a totally functional penicillin production plant from from bath tubs, milk churns and book shelves.

Not surprisingly the media were extremely excited about this new wonder drug, but Florey and his colleagues were rather shy of publicity. Instead Fleming took the limelight. The Haber-Bosch process Ammonia revolutionised agriculture. It is also the most common gas in our atmosphere. Consequently a major limiting factor in agriculture has been the availability of nitrogen.

Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.

You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular.

In addition, it is used as a component in deep-sea breathing systems, as a coolant for superconducting magnets, and as a protective gas for many industrial processes such as arc welding and growing silicon wafers. Researchers use helium to study materials at very low temperatures, in a field called cryogenics, and in helium dating of radioactive rocks and minerals. Inhaling a small volume of the gas temporarily changes the tonal quality and pitch of one’s voice.

It can, however, be dangerous if done in excess. Abundance in nature Helium is the second most abundant element in the known universe, after hydrogen , constituting 23 percent of the elemental mass of the universe. It is concentrated in stars , where it is formed by two sets of nuclear fusion reactions: Based on this theory, the abundance of helium serves as a test of cosmological models.

In the Earth’s atmosphere, the concentration of helium by volume is only 5. In the Earth’s heterosphere a part of the upper atmosphere , helium and other lighter gases are the most abundant elements. Nearly all helium on Earth is a result of radioactive decay. The decay product is found in minerals of uranium and thorium , including cleveites, pitchblende , carnotite, monazite and beryl.
