  • Genetic barcodes can ensure authentic DNA fingerprints
    on May 21, 2020 at 4:25 pm

    Engineers at Duke University and the New York University's Tandon School of Engineering have demonstrated a method for ensuring that an increasingly popular method of genetic identification called "DNA fingerprinting" remains secure against inadvertent mistakes or malicious attacks in the field.

  • The genome of chimpanzees and gorillas could help to better understand human tumors
    on May 21, 2020 at 4:23 pm

    A new study by researchers from the Institute of Evolutionary Biology (IBE), a joint centre of UPF and the Spanish National Research Council (CSIC), shows that, surprisingly, the distribution of mutations in human tumours is more similar to that of chimpanzees and gorillas than that of other types of genetic mutations in humans.

  • Q&A: How synthetic biology will change us
    on May 21, 2020 at 3:30 pm

    John Cumbers is founder and CEO of SynBioBeta, a global network of biological engineers and entrepreneurs in a promising new scientific field known as "synthetic biology." The San Francisco Bay Area is a leader in this little-known but fast-growing industry, which reassembles the building blocks of life in imaginative and diverse ways.

  • Mysterious glowing coral reefs are fighting to recover
    on May 21, 2020 at 3:26 pm

    A new study has revealed why some corals exhibit a dazzling colorful display, instead of turning white, when they suffer 'coral bleaching' -- a condition which can devastate reefs and is caused by ocean warming. The scientists behind the research think this phenomenon is a sign that corals are fighting to survive.

  • Scientists identify gene linked to thinness that may help resist weight gain
    on May 21, 2020 at 3:26 pm

    Researchers used a genetic database of more than 47,000 people in Estonia to identify a gene linked to thinness that may play a role in resisting weight gain in metabolically healthy thin people. They show that knocking out this gene results in thinner flies and mice and find that expression of it in the brain may be involved in regulating energy expenditure.

  • Turtles get boost as Malaysian state to ban egg trade
    on May 21, 2020 at 3:01 pm

    A Malaysian state that is a major nesting site for turtles will ban the trade in their eggs, authorities said Thursday, in a boost for the threatened creatures.

  • Spiny lobster noises may be heard up to 3 kilometers away
    on May 21, 2020 at 3:00 pm

    Noises produced by European spiny lobsters—known as antennal rasps—may be detectable up to 3 kilometers underwater, according to a study in Scientific Reports. The sound, created when lobsters rub an extension of their antenna against a 'file' below their eyes, may be used for communication or to deter predators. Its detection could help conservation efforts, the study suggests.

  • After the bushfires, we helped choose the animals and plants in most need. Here's how we did it
    on May 21, 2020 at 2:40 pm

    No other event in our lifetimes has brought such sudden, drastic loss to Australia's biodiversity as the last bushfire season. Governments, researchers and conservationists have committed to the long road to recovery. But in those vast burnt landscapes, where do we start?

  • The self-synthesizing ribosome
    on May 21, 2020 at 2:30 pm

    As the cell's protein factory, the ribosome is the only natural machine that manufactures its own parts. That is why understanding how the machine, itself, is made, could unlock the door to everything from understanding how life develops to designing new methods of drug production. An intensive, long research effort at the Weizmann Institute of Science has now demonstrated the self-synthesis and assembly of the small subunit of a ribosome -30S—on a surface of a chip.

  • Virus prevalence associated with habitat
    on May 21, 2020 at 2:26 pm

    Levels of virus infection in lobsters seem to be related to habitat and other species, new studies of Caribbean marine protected areas have shown.

  • Why bats don't get sick from the viruses they carry, but humans can
    on May 21, 2020 at 2:20 pm

    One of the first questions scientists ask when a new disease appears is, "Where did this come from?"

  • Genetic study suggests domestic goats got pathogen-resistant gene from wild relatives
    on May 21, 2020 at 2:10 pm

    An international team of researchers has found evidence that suggests wild relatives of domestic goats passed on a gene to their domesticated relatives that boosts their pathogen resistance. In their paper published in the journal Science Advances, the group describes their study of goat genetic history and what they learned from it.

  • 'Vampire fish' gorged on Great Lakes trout until the invasive species was subdued
    on May 21, 2020 at 2:10 pm

    A sea lamprey has no jaw, no proper teeth and no bones. Yet this predator can attach like a suction cup to a fish 100 times its size, use its tongue to burrow a hole into its side, liquefy its tissues and eat it.

  • Scientists alter genes of innate immune cells with DNA-snipping tool
    on May 21, 2020 at 1:58 pm

    A UCLA research team has successfully used the powerful gene-editing tool known as CRISPR-Cas9 to alter the DNA of mature innate immune cells, some of the body's first responders to infections. These blood cells have been notoriously difficult to genetically engineer in the past.

  • Mammoths, mastodons and the fruit they left behind at Fermilab
    on May 21, 2020 at 1:45 pm

    Scientists at the Department of Energy's Fermi National Accelerator Laboratory are constantly pushing at the boundaries of the unknown in their attempt to understand the origin and physical properties of the universe. Yet Fermilab is more than a gateway to the subatomic world: It's also home to rare and endangered ecosystems, such as grassland prairies and riparian forests, which are becoming increasingly hard to find in the northern United States.

  • New velvet gecko discovered on one of Australia's northern islands
    on May 21, 2020 at 1:40 pm

    Scientists from Queensland Museum, Griffith University, University of Melbourne and the Northern Territory Government have described a colorful new velvet gecko from Groote Eylandt in the Northern Territory.

  • Physicists exploring use of Blu-ray disc lasers to kill COVID-19, other viruses
    on May 21, 2020 at 1:32 pm

    A new weapon in the arsenal against the coronavirus may be sitting in your home entertainment console. A team led by physicist Chris Barty of the University of California, Irvine is researching the use of diodes from Blu-ray digital video disc devices as deep-ultraviolet laser photon sources to rapidly disinfect surfaces and the indoor air that swirls around us.

  • The ins and outs of sex change in medaka fish
    on May 21, 2020 at 1:31 pm

    Larval nutrition plays a role in determining the sexual characteristics of Japanese rice fish, also called medaka (Oryzias latipes), report a team of researchers led by Nagoya University. The findings, published in the journal Biology Open, could further understanding of a rare condition in humans and other vertebrates, where they genetically belong to one sex but also have characteristics of the other.

  • Sex as stress management in microbes
    on May 21, 2020 at 1:23 pm

    Why is sex so popular? The question of why so many organisms reproduce sexually has mystified evolutionary biologists since before Darwin, who wrote, "The whole subject is as yet hidden in darkness." In a recent article in Genome Biology and Evolution titled "What's genetic variation got to do with it? Starvation-induced self-fertilization enhances survival in Paramecium," the authors suggest that the molecular mechanisms underlying sex and the stress response may be more tightly coupled than previously appreciated, providing a new explanation for the widespread prevalence of sex in nature.

  • Plant virus-like particles as vehicles for therapeutic antibodies
    on May 21, 2020 at 1:22 pm

    Monoclonal antibodies are those that originate from identical immune cells having a common origin. They are highly effective, non-toxic and can specifically target diseased cells, and are therefore used in immunotherapy to treat diseases such as psoriasis, cancer and autoimmune disorders. However, since antibodies are unable to cross the cell membrane, they have mainly been used against antigens present on the surface of cells.

  • Should tomatoes go in the fridge?
    on May 21, 2020 at 1:22 pm

    There is much debate about the correct storage of tomatoes. There are two main options available to consumers: Storage in the refrigerator or at room temperature. A research team from the University of Göttingen has now investigated whether there are differences in the flavor of ripe tomatoes depending on how they are stored and taking into account the chain of harvesting from farm to fork. No perceptible difference was found: the variety of tomato is much more important. The results have been published in the journal Frontiers in Plant Science.

  • The genome of jojoba: The only plant to store wax in its seeds
    on May 21, 2020 at 1:22 pm

    The seeds of jojoba are one of the only known sustainable sources of liquid wax esters. They have been used as an eco-friendly replacement for similar oils that were once harvested from the spermaceti organ of the sperm whale (Physeter macrocephalus), which nearly drove it to extinction. "Jojoba is the only plant to store wax in its seeds. Such a vegetable oil has heretofore been unavailable," says Dr. Eberhard Munz (research group AAN).

  • Grasshoppers are perfectly aware of their own coloration when trying to camouflage
    on May 21, 2020 at 1:21 pm

    A research team from the Pablo de Olavide University of Seville, led by Pim Edelaar, from the institution's Department of Molecular Biology and Biochemical Engineering, has carried out an experimental study that shows that grasshoppers are perfectly aware of their own coloration when choosing the place that provides them with better camouflage. The research findings, published in the journal Proceedings of the Royal Society B, show how organisms are able to adjust their environment, each according to their individual needs.

  • 'Heat resistant' coral developed to fight bleaching
    on May 21, 2020 at 12:47 pm

    A team of scientists has successfully produced in a laboratory setting a coral that is more resistant to increased seawater temperatures.

  • I'm an NHS doctor – and I've had enough of people clapping for me
    by Anonymous on May 21, 2020 at 8:31 am

    The health service is not a charity and it is not staffed by heroes. It has been run into the ground by successive governmentsCoronavirus – latest updatesSee all our coronavirus coverageI work for the NHS as a doctor. I don’t work “on the frontline” because there isn’t one; I’m not in the army and we aren’t engaged in military combat. But I do work as a consultant on a ward where we have had Covid-19, and colleagues of mine have been very unwell. The requirement to be constantly vigilant and to manage the infection risk makes work more difficult, more stressful, and at times more tragic.Obviously I carry on going to work – it is my job, one that I enjoy and am being well paid for. I am pleased to have a reason to leave the house. I have a very decent and secure income so count myself extremely lucky.
