Monkeys Built to Mimic Autism-Like Behaviors May Help Humans - The New York Times - 0 views

  •  
    Scientists have genetically engineered monkeys so that they exhibit behaviors similar to autism, with a goal of testing potential therapies on the animals in hopes that their resemblance to humans will yield more answers about the disorder. The scientists found that the monkeys showed "very similar behaviors related to human autism patients, including repetitive behaviors, increased anxiety and, most importantly, defects in social interactions," said Zilong Qiu, a leader of the research at the Institute of Neuroscience at the Chinese Academy of Sciences in Shanghai. The team is now imaging the brains of the monkeys, he said, "trying to identify the deficiency in the brain circuits that is responsible for the autism-like behavior."

First Human Test of Optogenetics Could Restore Sight to the Blind - D-brief - 0 views

  •  
    A decade-old technique that allows researchers to control brain function in lab animals could partially restore sight to the blind. In a trial sponsored by RetroSense Therapeutics, a startup company in Ann Arbor, Michigan, doctors will inject a harmless virus loaded with DNA from photoreceptive algae into the eyes of 15 patients suffering from retinitis pigmentosa. The experimental procedure represents the first human test of optogenetics, which is a technique that genetically modifies neurons to make them responsive to light. Doctors from the Retina Foundation of the Southwest will perform the procedure, and attempt to transfer the job duties of photoreceptor cells to different cells in the eye to restore sight.

Butterflies in the Stomach - National Center for Case Study Teaching in Science - 0 views

  •  
    Why is the North American population of monarch butterflies declining? In 1999, a study published in the journal Nature suggested that a variety of genetically modified corn was killing these iconic butterflies. While it was later shown that the conditions in this study did not mirror those in the field, the results garnered a lot of media attention and many people today still believe that monarchs are being killed by GMOs. This case familiarizes students with the plight of the monarchs, encourages them to think about how to test the hypothesis that a toxin is responsible for their decline, and takes a critical look at several studies that investigated the role of Bt corn in the life cycle of monarchs. This interrupted case takes 60-90 min to complete, requires little to no science background, and can be used to explore the ecology and wildlife management of monarchs; risk assessment, toxicity, and exposure; experimental design, the scientific method, hypothesis, and critical thinking; or the relationship between science, the media and the public.

Correcting sickle cell disease with stem cells -- ScienceDaily - 0 views

  •  
    Using a patient's own stem cells, researchers have corrected the genetic alteration that causes sickle cell disease, a painful, disabling inherited blood disorder that affects mostly African-Americans. The corrected stem cells were coaxed into immature red blood cells in a test tube that then turned on a normal version of the gene

Mosquitoes 'lured by body odour genes' - BBC News - 0 views

  •  
    Researchers tested pairs of identical and non-identical twins to see how attractive they were to mosquitoes. Identical twins were more likely to have similar levels of attractiveness - suggesting shared genetic factors were at play. The "intriguing" results must now be assessed in larger trials, experts say. Researchers have long tried to understand what drives mosquitoes to bite certain people more than others. Recent work shows the insects may be lured to their victims by body odour.

Genome | How Personalized Medicine Is Changing: Alzheimer's Disease - 0 views

  •  
    By then, researchers had identified three genetic mutations that can be inherited and, if they are, cause a form of Alzheimer's called early onset because it strikes before age 65 and sometimes far earlier. Since 2004, Hornstein and all five of her siblings have been tested. Hornstein is the only one who doesn't carry PSEN1, one of the mutations.

Becoming a Friend Instead of a Foe - National Center for Case Study Teaching in Science... - 0 views

  •  
    This case study centers on symbiotic relationships between insects and bacteria using Drosophila melanogaster, the common fruit fly, and the recently discovered bacterial species Sodalis praecaptivus. Until recently, the only known Sodalis species of bacteria were symbiotically associated with several different species of insects. However, free-living non-symbiont Sodalis species are being tested in several different insect species to determine if they can transition into symbiotic relationships. A pre-class assignment (see Supplemental Materials) directs students to read an open access research journal article providing a comprehensive review of S. praecaptivus and describing an experimental weevil model that parallels that of the fruit fly. A PowerPoint presentation shown in class (see Supplemental Materials) provides further background before students work in small groups to complete the case study focusing on results from D. melanogaster and S. praecaptivus model experiments.  Although developed for a genetics course, this interrupted case is appropriate for an upper-level biology course. It can be completed within a 75-minute class meeting, or adapted for shorter time periods.

Exclusive: A new test can predict IVF embryos' risk of having a low IQ | New Scientist - 0 views

  •  
    THE prospect of creating intelligent designer babies has been the subject of ethical debate for decades, but we have lacked the ability to actually do it. That may now change, thanks to a new method of testing an embryo's genes that could soon be available in some IVF clinics in the US, New Scientist can reveal.

Community Activities | Digital World Biology - 0 views

  •  
    With support from the National Science Foundation, we assisted in developing bioinformatics curriculum for high schools and popular bioinformatics tutorials that are used in both college and high school classes. We have shared these materials at several Bio-Link workshops, and at workshops sponsored by CCURI, Tulsa Community College (SEEDBed award), and DelMar College.  Digital World Biology is also partnering with the Amgen Biotech Experience at Shoreline Community College to assist in providing professional development opportunities for high school teachers.

So is it nature not nurture after all? | Science | The Guardian - 0 views

  •  
    There are few areas of science more fiercely contested than the issue of what makes us who we are. Are we products of our environments or the embodiment of our genes? Is nature the governing force behind our behaviour or is it nurture? While almost everyone agrees that it's a mixture of both, there has been no end of disagreement about which is the dominant influence.
