    These beautiful noctilucent clouds once rare are being seen more often and at lower latitudes. Scientists think noctilucent clouds could be a sign of global climate change. What are these clouds and why are they being seen more often.

Use of DNA evidence is not an open and shut case, professor says - 0 views

book DNA evidence The Double Helix and the Law of Evidence

  • In his new book, "The Double Helix and the Law of Evidence" (Harvard University Press), Kaye focuses on the intersection of science and law, and emphasizes that DNA evidence is merely information. "There's a popular perception that with DNA, you get results," Kaye said. "You're either guilty or innocent, and the DNA speaks the truth. That goes too far. DNA is a tool. Perhaps in many cases it's open and shut, in other cases it's not. There's ambiguity."
  • One of the book's key themes is that using science in court is hard to do right. "It requires lawyers and judges to understand a lot about the science," Kaye noted. "They don't have to be scientists or technicians, but they do have to know enough to understand what's going on and whether the statements that experts are making are well-founded. The lawyers need to be able to translate that information into a form that a judge or a jury can understand." Kaye also believes that lawyers need to better understand statistics and probability, an area that has traditionally been neglected in law school curricula. His book attempts to close this gap in understanding with several sections on genetic science and probability. The book also contends that scientists, too, have contributed to the false sense of certainty, when they are so often led by either side of one particular case to take an extreme position. Scientists need to approach their role as experts less as partisans and more as defenders of truth. Aiming to be a definitive history of the use of DNA evidence, "The Double Helix and the Law of Evidence" chronicles precedent-setting criminal trials, battles among factions of the scientific community and a multitude of issues with the use of probability and statistics related to DNA. From the Simpson trial to the search for the last Russian Tsar, Kaye tells the story of how DNA science has impacted society. He delves into the history of the application of DNA science and probability within the legal system and depicts its advances and setbacks.

    Whether used to clinch a guilty verdict or predict the end of a "CSI" episode, DNA evidence has given millions of people a sense of certainty -- but the outcomes of using DNA evidence have often been far from certain, according to David Kaye, Distinguished Professor of Law at Penn State.

    "Plastic is produced in large amounts and used for various purposes. After use, huge amounts end up in the enviroment, often in the oceans. There, fragmentation leads to small particles, called microplastics. By filtrating and benthos-feeding organisms it can be inadvertently taken up as food. We demonstrate that the unicellular ciliate Paramecium, the freshwater flea Daphnia and the blue mussel Mytilus took up microplastic particles. Even more, in Mytilus, the plastic particles were transported into the digestive gland and accumulated in the respective cells. Subsequently, pathological alterations in the gland were noted. Microplastics are of concern because animals might starve with a full belly after uptaking large amounts of microplastics. As well, particles with sharp edges can injure the mucous layer of the gastrointestinal tract. Furthermore, persistent organic pollutants adhere at plastic and thus, may cause adverse impacts on the animal. We show options for solutions and indicate selected organisations working on the development of solution"

    "How many mammal species live in the forest? It sounds like a simple question, but the actual distributions of shy, small or rare mammals are often murky, confounding conservationists seeking to protect them. Yet a paper published online on Tuesday in the journal Molecular Ecology explores a new way to track biodiversity: by capturing flies that feed on carcasses. The flies' stomachs offer DNA diaries of their recent meals, giving scientists clues to which animals live and die in the forest. "The animals are there, but you just don't see them," said Fabian Leendertz, a wildlife epidemiologist at the Robert Koch Institute in Berlin and an author of the paper. "Those flies will find them and will tell us what is there"

    "Tissue engineering is often thought of as a "Frankenstein-type" science where scientists build living tissues from otherwise "dead" tissues and organs. However, current advances in technology mean bringing life to cadaveric tissues is becoming more and more sophisticated: less of the lightning strikes and more stem cells and 3D printing!"

    The vision of a national digital library has been circulating among librarians, scholars, educators, and private industry representatives since the early 1990s, but it has not yet materialized. Efforts led by a range of organizations, including the Library of Congress, HathiTrust, and the Internet Archive, have successfully built resources that provide books, images, historical records, and audiovisual materials to anyone with Internet access. Many universities, public libraries, and other public-spirited organizations have digitized materials that could be brought together under the frame of the DPLA, but these digital collections often exist in silos.

    "We often think that the limiting factors to doing science are intellectual or technological. There are many unsolved scientific problems that we know how to answer. We aren't waiting for any conceptual breakthroughs or new technologies. We're waiting for people. We need "hands at the bench" to put in the time to collect the data. The instabilities of salary is a major limiting factor for science and is probably a big reason a lot of them get out of science: they don't see a way to pay the bills. Creating permanent, stable positions for scientists would release a lot of scientific research."

    "Understanding the relationship between diversity and stability requires a knowledge of how species interact with each other and how each is affected by the environment. The relationship is also complex, because the concept of stability is multifaceted; different types of stability describing different properties of ecosystems lead to multiple diversity-stability relationships. A growing number of empirical studies demonstrate positive diversity-stability relationships. These studies, however, have emphasized only a few types of stability, and they rarely uncover the mechanisms responsible for stability. Because anthropogenic changes often affect stability and diversity simultaneously, diversity-stability relationships cannot be understood outside the context of the environmental drivers affecting both. This shifts attention away from diversity-stability relationships toward the multiple factors, including diversity, that dictate the stability of ecosystems."

    " Of course, skeptics hope that their efforts aid in advancing science education.1 In spite of these efforts, survey data from several sources suggests that paranormal belief and pseudoscientific thinking continue to be commonplace.2 Skeptics often use these findings to reinforce arguments for more science education. Their argument is based upon the largely untested assumption that increased science knowledge reduces the number of paranormal beliefs an individual holds. However, this assumption may not be valid. Andrew Ede recently argued that science education may do little to raise the level of rational thinking and may, in fact, actually deter it!"

    "Researchers say they want to emphasize, however, that the HPV vaccine commonly used by millions of women around the world is perfectly safe if done prior to infection with the virus. The concerns raised by this study relate only to viral therapies or possible use of a therapeutic vaccine after the virus has already been integrated into human cells. "It's been known for decades that only women with prior infection with HPV get cervical cancer," said Andrey Morgun, an assistant professor and a leader of the study in the OSU College of Pharmacy. "In about 90 percent of cases it's naturally eliminated, often without any symptoms. But in a small fraction of cases it can eventually lead to cancer, in ways that have not been fully understood.""

    "So far the treatment, known as faecal transplant, has been tested only on a drug resistant form of the bowel disease caused by the bacterium clostridium difficile. Antibiotics are unreliable against the superbug, but the transplant is 95% successful, saving patients from constant stomach cramps and chronic diarrhoea. "It sounds radical but it makes a lot of sense," said Seppelt on Thursday at a gathering of more than 4,000 Australasian anaesthetists and surgeons. "Usually patients are sufficiently miserable to go ahead, often using a donation from a relative." Healthy humans have about 100 times more bacteria cells in their gut than their own cells."

    Bacteria are often social creatures. Suspended in colonies of varying shapes and sizes, these microbes communicate with their brethren and even other bacterial species - interactions that can sometimes make them more deadly or more resistant to antibiotics. Now, bacterial colonies sculpted into custom shapes by a 3-D printer could be a key to understanding how some antibiotic-resistant infections develop. The new technique uses methods similar to those employed by commercial 3-D printers, which extrude plastic, to create gelatin-based bacterial breeding grounds. These microbial condos can be carved into almost any three-dimensional shape, including pyramids and nested spheres.

    We belong to a remarkably quirky species. Despite our best efforts, some of our strangest foibles still defy explanation. But as science probes deeper into these eccentricities, it is becoming clear that behaviours and attributes that seem frivolous at first glance often go to the heart of what it means to be human.

When one remembers that research journals often go for hundreds of dollars per year in hardcopy form, a resource like this is appreciated even more, in this time of widespread long term unemployment in the pure and applied sciences.

    What do quantum particles do when we're not looking? Probably not what you'd expect.\n\nWhile the mathematical formalism 'behind the scenes' is perfectly well-defined and the predictions by the theory are completely sensible (and rigorously tested), it is often difficult to interpret the mechanism of quantum theory into ideas that make sense relative to everyday experiences.

    It's just plain silly to make claims like this about a basic science paper given that, as I have discussed before, it often takes decades for basic science observations to wend their way through that long strange trip to becoming actual therapies used by clinicians. The life cycle of translational research is long, and efforts to speed it up have only met with mixed success.
