There's No Scientific Basis for Race-It's a Made-Up Label - 1 views

  •  
    Over the past few decades, genetic research has revealed two deep truths about people. The first is that all humans are closely related-more closely related than all chimps, even though there are many more humans around today. Everyone has the same collection of genes, but with the exception of identical twins, everyone has slightly different versions of some of them. Studies of this genetic diversity have allowed scientists to reconstruct a kind of family tree of human populations. That has revealed the second deep truth: In a very real sense, all people alive today are Africans.

Anencephaly in Yakima - National Center for Case Study Teaching in Science - 0 views

  •  
    This case study explores the recent (2010 - 2016) outbreak of neural tube defects, specifically anencephaly, in a rural three-county region of Washington state, particularly Yakima, WA. The case study focuses on the biological aspects of teratogens that may cause birth defects as well as epidemiological investigations of disease outbreaks. By the end of the case, students will have explored how our environment may have severe biological consequences on the human body during pregnancy and will have evaluated governmental and scientific investigations of a rare outbreak of birth defects. This clicker case study was developed for a non-majors biology course entitled "Human Development: Conception to Birth," although it could be taught in any introductory biology course for majors or non-majors during a unit on human reproductive biology or developmental biology. The case assumes that students have no prior knowledge of developmental biology or birth defects. The case study could also be adapted for upper-division courses by getting more in-depth on the specifics of teratogen mechanisms, the developmental biology and physiology of neural tube defects, or more complex epidemiological analyses.

Why Is He Different from Both Parents? - National Center for Case Study Teaching in Sci... - 0 views

  •  
    This case study was developed to teach the topic of human ABO blood type and genetic inheritance in biology courses at the lower undergraduate level or upper high school level. It is suitable for entry level biology, genetics, and physiology courses. The case narrative tells the story of Kevin, a teenager who is puzzled by the fact that neither of his parents can donate blood to him. He and his best friend ask their biology teacher for help, and she explains human ABO blood types at the molecular and genetic level to solve the mystery. The case consists of three sections, which can be used sequentially or separately. After completing the case study, students will understand the molecular basis of ABO blood types and how genes control the phenotype and genotype of an individual. They will also have a better understanding of how human ABO blood type is inherited from generation to generation.

Cold Tolerance Among Inuit May Come From Extinct Human Relatives - The New York Times - 0 views

  •  
    A new study, published on Wednesday in Molecular Biology and Evolution, identifies gene variants in Inuit who live in Greenland, which may help them adapt to the cold by promoting heat-generating body fat. These variants possibly originated in the Denisovans, a group of archaic humans who, along with Neanderthals, diverged from modern humans about half a million years ago.

Asthma cure on the horizon? | Foundation for Biomedical Research - 0 views

  •  
    Millions of people suffer from asthma, a frightening disease that makes you feel like you're drowning. Using both mouse and human cells - and a humanized mouse to show how human type 2 innate lymphoid cells (ILC2) work in the body, researchers at Janssen Research and Development, Dana-Farber Cancer Institute and Harvard Medical School are figuring out ILC2's role in asthma. Their findings have important implications in the quest for effective asthma therapies!

Artificial intelligence joins hunt for human-animal diseases : Nature News & Comment - 0 views

  •  
    Lyme disease, Ebola and malaria all developed in animals before making the leap to infect humans. Predicting when such a 'zoonotic' disease will spark an outbreak remains difficult, but a new study suggests that artificial intelligence could give these efforts a boost. A computer model that incorporates machine learning can pinpoint, with 90% accuracy, rodent species that are known to harbour pathogens that can spread to humans, researchers report this week in the Proceedings of the National Academy of Sciences1. The model also identified more than 150 species that are likely to be disease reservoirs but have yet to be confirmed as such.

Genomic Elements Reveal Human Diversity | The Scientist Magazine® - 0 views

  •  
    Genetic differences among ethnically diverse individuals are largely due to structural elements called copy number variants (CNVs), according to a study published today (August 6) in Science. Compared with other genomic features, such as single nucleotide variants (SNVs), CNVs have not previously been studied in as much detail because they are more difficult to sequence. Covering 125 distinct human populations around the world, geneticist Evan Eichler at the University of Washington in Seattle and an international team of colleagues studied the genomes of 236 people-analyzing both SNVs and CNVs. "The take-home message is that we continue to find a lot more genetic variation between humans than we appreciated previously," Eichler told The Scientist.

  •  
    Species like yeast, flies, fish and mice have many genes in common with humans and are therefore considered 'model organisms' and are widely used in research to study human genes and human diseases. Mouse research has lead to major advances in our ability to treat a number of serious diseases and conditions.

GSA PREP Resource: Human Genetic Variation | Genetics Society of America - 0 views

  •  
    This interactive case discussion was created to emphasize the clinical relevance of population genetics, but is also a suitable resource for teaching the basic principles of population genetics while relating them to human genetic variation. Our understanding of human genetic variation has deepened over the past decade due to fine-scale genome mapping. Applying this knowledge to the evaluation of ancestry-based genetic testing strategies, such as direct-to-consumer genetic testing, is an important component of the practice of culturally-competent medicine and a relevant way to teach the foundations of population genetics, including Hardy-Weinberg equilibrium.

Mice can teach us about human disease | Science News for Students - 0 views

  •  
    While humans and mice look and act very differently, 85 to 90 percent of our genes are the same or similar. So if scientists can understand the instructions in every mouse gene, people will get a good idea of the instructions in virtually every human gene as well.

Can humans get norovirus from their dogs? | EurekAlert! Science News - 0 views

  •  
    Washington, D.C. - April 10, 2015 - Human norovirus may infect our canine companions, according to research published online April 1 in the Journal of Clinical Microbiology, a publication of the American Society for Microbiology. That raises the possibility of dog-to-human transmission, said first author Sarah Caddy, VetMB, PhD, MRCVS, a veterinarian and PhD student at the University of Cambridge, and Imperial College, London, UK. Norovirus is the leading cause of food-borne illness in the United States, according to the Centers for Disease Control and Prevention (CDC).

Shedding Light On Human Cancer By Studying Canine Cancer | KCUR - 0 views

  •  
    Dr. Carolyn Henry, a veterinary oncologist at the University of Missouri veterinary school, says that, unlike lab mice, dogs get cancer naturally, just like humans. So their cancers are more likely to behave like human cancer when treated. "It's the same disease, it really doesn't matter what the species is," Henry says. "It's the same disease if it occurs naturally. And so, answers in one species should translate to answers in other species in many cases."

Scientists Seek Moratorium on Edits to Human Genome That Could Be Inherited - NYTimes.com - 0 views

  •  
    An international group of scientists meeting in Washington called on Thursday for what would, in effect, be a moratorium on making inheritable changes to the human genome. The group said it would be "irresponsible to proceed" until the risks could be better assessed and until there was "broad societal consensus about the appropriateness" of any proposed change. The group also held open the possibility for such work to proceed in the future by saying that as knowledge advances, the issue of making permanent changes to the human genome "should be revisited on a regular basis."

How Much Sleep Do We Really Need? Humans, like all... - 0 views

  •  
    Humans, like all animals, need sleep, along with food, water and oxygen, to survive. For humans sleep is a vital indicator of overall health and well-being. We spend up to one-third of our lives asleep, and the overall state of our "sleep health " remains an essential question throughout our lifespan. Most of us know that getting a good night's sleep is important, but too few of us actually make those eight or so hours between the sheets a priority. For many of us with sleep debt, we've forgotten what "being really, truly rested" feels like.
