Scientists Are Cracking the Primordial Soup Mystery

derekmead writes “Scientists have had a basic understanding of how life first popped up on Earth for a while. The so-called ‘primordial soup’ was sitting around, stagnant but containing the basic building blocks of life. Then something happened and we ended up with life. It’s that ‘something’ that has been the sticking point for scientists, but new research from a team of scientists at the University of Leeds has started to shed light on the mystery, explaining just how objects from space might have kindled the reaction that sparked life on Earth. It’s generally accepted that space rocks played an important role in life’s genesis on Earth. Meteorites bombarding the planet early in its history delivered some of the necessary materials for life but none brought life as we know it. How inanimate rocks transformed into the building blocks of life has been a mystery. But this latest research suggests an answer. If meteorites containing phosphorus landed in the hot, acidic pools that surrounded young volcanoes on the early Earth, there could have been a reaction that produced a chemical similar one that’s found in all living cells and is vital in producing the energy that makes something alive.”

Scientists Study Getting an Unwanted Tune Out of Your Head

Hugh Pickens writes writes “Richard Gray reports that scientists have found a way to help anyone plagued by those annoying tunes that lodge themselves inside our heads and repeat on an endless loop — when snippets of a catchy song inexplicably play like a broken record in your brain. The solution can be to solve some tricky anagrams to force the intrusive music out of your working memory allowing the music to be replaced with other more amenable thoughts. ‘The key is to find something that will give the right level of challenge,’ says Dr Ira Hyman, a music psychologist at Western Washington University who conducted the research. ‘If you are cognitively engaged, it limits the ability of intrusive songs to enter your head.’ Hyman says that the problem, called involuntary memory retrieval, is that something we can do automatically like driving or walking means you are not using all of your cognitive resource, so there is plenty of space left for that internal jukebox to start playing. Dr Vicky Williamson, a music psychologist at Goldsmiths, University of London, says that the most likely songs to get stuck are those that are easy to hum along to or sing and found that that Lady Gaga was the most common artist to get stuck in people’s heads, with four of her catchy pop songs being the most likely to become earworms – Alejandro, Bad Romance, Just Dance and Paparazzi. Other surveys have reported Abba songs such as Waterloo, Changes by David Bowie or the Beatles’ Hey Jude.”

How Scientists Know An Idea Is a Good One

Physicist Chris Lee explains one of the toughest judgment calls scientists have to make: figuring out if their crazy ideas are worth pursuing. He says: “Research takes resources. I don’t mean money—all right, I do mean money—but it also requires time and people and lab space and support. There is a human and physical infrastructure that I have to make use of. I may be part of a research organization, but I have no automatic right of access to any of this infrastructure. … This also has implications for scale. A PhD student has the right to expect a project that generates a decent body of work within those four years. A project that is going to take eight years of construction work before it produces any scientific results cannot and should not be built by a PhD student. On the other hand, a project that dries up in two years is equally bad. … the core idea also needs to be structured so, should certain experiments not work, they still build something that can lead to experiments which do work. Or, if the cool new instrument we want to build can’t measure exactly what I intended, there are other things it can measure. One of those other things must be fairly certain of success. To put it bluntly: all paths must lead to results of some form.”

Scientists 3D-print embryonic stem cells, pave the way for lab-made organ transplants

Image

3D printers already have a firm footing the commercial market, with more than 20 models available for well-heeled DIYers, and the technology’s appeal isn’t lost on the scientific community. A team at Heriot-Watt University in Edinburgh, Scotland has developed a method for 3D-printing clusters of human embryonic stem cells in a variety of sizes. Researchers have successfully printed 3D cells before, but this is the first time that embryonic cell cultures, which are especially delicate, have been built in three dimensions. Human embryonic stem cells can replicate almost any type of tissue in the human body — and the scientists at Heriot-Watt believe that lab-made versions could one day be used to make organ transplants, thereby rendering donors unnecessary. In the nearer future, 3D-printed stem cells could be used to make human tissue models for drug testing; effectively eliminating the need for animal testing. Makes that Burritob0t look a little less ambitious, doesn’t it?

Male Scientists More Prone To Misconduct

sciencehabit writes “Male scientists — especially at the upper echelons of the profession — are far more likely than women to commit misconduct. That’s the bottom line of a new analysis by three microbiologists of wrongdoing in the life sciences in the United States. Ferric Fang of the University of Washington, Seattle; Joan Bennett of Rutgers University; and Arturo Casadevall of Albert Einstein College of Medicine combed through misconduct reports on 228 people released by the U.S. Office of Research Integrity (ORI) over the last 19 years. They then compared the gender balance — or imbalance, in this case — against the mix of male and female senior scientists and trainees to gauge whether misconduct was more prevalent among men. A remarkable 88% of faculty members who committed misconduct were men, or 63 out of 72 individuals. The number of women in that group was one-third of what one would expect based on female representation in the life sciences.”

Cambridge University Scientists Find Quadruple Helix DNA In Human Cells

SternisheFan notes that scientists at Cambridge University have found four-stranded DNA in human cells for the first time. “If you’ve ever studied genetics in school or college, you’ll know that the structure of DNA is a double helix. You likely know that DNA carries all of our genetic code. While traditionally we think of only double helix DNA, scientists from Cambridge University in England have made an interesting discovery. According to the researchers, a quadruple helix is also present in some cells and is believed to relate to cancer in some ways. According to the researchers, controlling these quadruple helix structures could provide new ways to fight cancer. The scientists believe the quadruple helix may form when the cell has a certain genotype or operates in a certain dysfunctional state. Scientists have been able to produce quadruple helix material in test tubes for years. The material produced is called the G-quadruplex. The G refers to guanine, which is one of the base pairs that hold DNA together. The new research performed at the University is believed to be the first to firmly pinpoint quadruple helix in human cells.”

They created their fuel using a fermentation process that was first discovered in 1914, but which was then discontinued in 1965 when petroleum became the dominant source of fuel. The new fuel actually contains more energy per gallon than is currently contained in ethanol, and its potency can even be adjusted for summer or winter driving.”
