  1. Plants under heat stress must act surprisingly quickly to survive

    08.21 / 18:42 eurekalert.org Eurekalert.org - Biology
    (University of Massachusetts at Amherst) In The Plant Cell, UMass Amherst molecular biologist Elizabeth Vierling reports that heat-stressed plants not only need to produce new proteins to survive the stress, they need to make them right away. 'We found that a delay of even six hours of new protein translation will inhibit optimal growth and reproduction. The plants might not outright die, but they are severely impaired without the rapid synthesis of these new…
  2. Searching for the 'signature' causes of BRCAness in breast cancer

    08.21 / 16:46 eurekalert.org Eurekalert.org - Biology
    (Broad Institute of MIT and Harvard) Breast cancer cells with defects in the DNA damage repair-genes BRCA1 and BRCA2 have a mutational signature known in cancer genomics as 'Signature 3.' But not all breast tumor cells exhibiting Signature 3 have BRCA1 or BRCA2 mutations. Therefore, some consider Signature 3 a biomarker for 'BRCAness,' a sign of a breakdown in BRCA-related DNA repair in general and not BRCA damage in…
  3. Collaborative effort aims to replace rabbit test for personal lubricant products

    08.21 / 16:46 eurekalert.org Eurekalert.org - Biology
    (Institute for In Vitro Sciences) A first-of-its kind collaborative project is underway to find a non-animal test method to replace the rabbit vaginal irritation test for personal lubricants. The US Food and Drug Administration gave the project a green light as part of the agency's program aimed at modernizing the tests used to develop and evaluate medical…
  4. Penn Medicine receives NIH training grants for genomic medicine

    (University of Pennsylvania School of Medicine) The University of Pennsylvania is the first institution with more than one training grant from the National Human Genome Research Institute, now with…
  5. Both chimpanzees and humans spontaneously imitate each other's actions 

    08.21 / 14:39 eurekalert.org Eurekalert.org - Biology
    (Lund University) Decades of research has shown that apes, in spite of their proverbial aping abilities, are rather poor imitators, especially when compared to human children. Current theories hold that apes are worse imitators because they lack this social and communicative side of imitation. A new study from Lund University, published in the journal Primates, has instead targeted the interactive side of imitation directly, and finds that the divide between humans and chimpanzees is less…
  6. Biochemical 'fingerprints' reveal diabetes progression

    08.21 / 14:39 eurekalert.org Eurekalert.org - Biology
    (Umea University) Researchers from Umeå University in Sweden describe a new method to study biochemical changes that occur in the pancreas during the development of diabetes. The method, recently published in Scientific Reports, is based on molecular spectroscopy and can be used to extract biochemical profiles (or 'fingerprints') containing information about disease progression. The method could facilitate improved understanding of the mechanistic processes on molecular and cellular…
  7. Have flowers devised the ultimate weapon of distraction?

    08.21 / 08:31 eurekalert.org Eurekalert.org - Biology
    (University of Portsmouth) Nectar, the high-energy 'honey' produced by flowers, might be a brilliant distraction technique to help protect a flower's reproductive parts, according to new research.Rather than merely providing a 'come-on' to bees and other insects to attract them to pollinate the flower, nectar could be playing a much more subtle and entrancing…
  8. Wood frogs research clarifies risks posed to animals by warming climate

    08.19 / 14:29 eurekalert.org Eurekalert.org - Biology
    (Penn State) As conditions warm, fish and wildlife living at the southern edge of their species' ranges are most at risk, according to Penn State researchers who led a major collaborative study of how wood frogs are being affected by climate…
