Modern industry is foundational for contemporary society. Yet, its dependence upon fossil fuels, primarily, and upon other chemicals, secondarily, threatens to destroy that very same society. One should note, at the outset, that those industrial processes do not so much create greenhouse gases, as they are termed, but rather release them. Global warming threatens to restore our planet to an ancient equilibrium – an equilibrium that was home to tropical plants and dinosaurs, but not to man.
Environmental sustainability includes an ‘if’. The ‘if’ is implied, but invariably left unstated. Sustainability means ‘ability to endure across time’. When used as a matter of physical limitation, no ‘if’ is implied or needed.
Another ‘Awareness Day’, International Kissing Day, is coming up on July 6. It might not seem obvious but kissing, like most subjects can now be easily linked to the science of DNA. Thus, there could be no more perfect opener for my Double Helix column, given the elegance and beauty of a kiss. To start, there is the obvious biological link between kissing and DNA: propagation of the species. Kissing is not only pleasurable but seems to be a solid way to assess the quality and suitability of a mate.
With more candidates entering the 2016 presidential race weekly, how do we decide which one deserves our vote? Is a good sense of humor important? Should she be someone we can imagine drinking beer with? Does he share our position on an issue that trumps all others in our minds? We use myriad criteria to make voting decisions, but one of the most important for me is whether the candidate carefully considers all the evidence bearing on the positions he advocates.
If you like your prophecies pin sharp then look away now. The 16th century celebrity seer Nostradamus excelled at the exact opposite, couching his predictions in terms so vague as to be largely meaningless. This has not, however, prevented his soothsayings attracting enormous and unending interest, and his book – Les Propheties – has rarely been out of print since it was first published 460 years ago. Uniquely, for a renaissance augur, the writings of Nostradamus are perhaps as popular today as they were four and a half centuries ago.
The latest incarnation (I chose that word advisedly!) of the Jurassic Park franchise has been breaking box-office records and garnering mixed reviews from the critics. On the positive side the film is regarded as scary, entertaining, and a bit comedic at times (isn’t that what most movies are supposed to be?). On the negative side the plot is described as rather ‘thin’, the human characters two-dimensional, and the scientific content (prehistoric animals) unreliable, inaccurate, or lacking entirely in credibility.
Environmental Epigenetics is a new, international, peer-reviewed, fully open access journal, which publishes research in any area of science and medicine related to the field of epigenetics, with particular interest on environmental relevance. With the first issue scheduled to launch this summer, we found this to be the perfect time to speak with Dr. Michael K. Skinner, Editor-in-Chief to discuss the launch of the journal into an exciting and rapidly developing field.
“In the spring a young man’s fancy lightly turns to thoughts of love” (Alfred, Lord Tennyson), but he could have said the same for insects too. Male insects will be following the scent of females, looking for a partner, but not every female is what she seems to be. It might look like the orchid is getting some unwanted attention in the video below, but it’s actually the bee that’s the victim. The orchid has released complex scents to fool the bee into thinking it’s meeting a female.
How does nature benefit our health? Many of us intuitively know that we simply feel better after ‘stepping out for some fresh air.’ Now over 30 years of research has begun to reveal exactly what health benefits we get from nature. Here are five reasons why we need to make space and time for nature in our lives.
Our brain lives in a symbiotic relationship with the bugs in our gut. Whatever we eat, they eat. In return, they help our brain function optimally in a variety of ways. During the past few years, it has become increasingly apparent that in the absence of bacteria humans would never have evolved to our current level of cognitive performance. Our brains are profoundly dependent upon a wide range of chemicals produced by these gut bugs.
One of the most fun and exciting sources of information available for free on the Internet are the videos found on the Technology, Entertainment and Design (TED) website. TED is a hub of stories about innovation, achievement and change, each artfully packaged into a short, highly accessible talk by an outstanding speaker. As of April 2015, the TED website boasts 1900+ videos from some of the most imminent individuals in the world. Selected speakers range from Bill Clinton and Al Gore to Bono and other global celebrities to a range of academics experts.
Green fluorescent proteins, or GFPs for short, are visibly advancing research in biology and medicine. By using GFPs to illuminate proteins otherwise undetectable under the microscope, scientists have learned a great deal about processes that take place within our cells.
Hop (Humulus lupulus L.) is an essential ingredient for brewing beer, and contributes a characteristic bitterness, aroma, and fullness. However, during the Middle-Ages, various other herbs including Rhodomyrtus tomentosa and Salix subfragilis, had also been used for brewing beer in Europe.
It was a simple request: “Try and put the fun back into microbiology”. I was about to write a new practical course for first year students, and apparently there had been complaints that microbiology is just another form of cookbook chemistry. Discussions showed that they liked the idea of doing their own experiments without a pre-determined outcome. Of course, with living microorganisms, safety must be a major concern, and some control was needed to prevent hazardous surprises, but “fun” and safety are not mutually exclusive.
Nipple of a cat. Nose of a pig. Hair of a poodle. Eyes of a baboon. Brain of a chimpanzee. If this sounds like a list of ingredients for a witches’ cauldron, think again, for it’s merely a reminder of how many general characteristics we share with other mammals. This similarity in basic body parts has a genetic basis. So humans and chimps share 99 percent DNA similarity in our protein–coding genes and even the tiny mouse is 85 percent similar to us in this respect.
On 18th May plant lovers around the world take part in Fascination of Plants Day to raise awareness of the importance of plant science to our lives. Well, what is so fascinating about plants? We asked some of our authors and editors to share why they think plants are fascinating and why they are worth studying.
