Science « Nonfiction Comics. The explanation of how DNA works can be as complicated as the organisms it helps put together. And yet, because this knowledge is essential to understanding the entire field of biology, we expect students to learn all about this alphabet soup, from ATGC to XX and XY. In The Stuff of Life: A Graphic Guide to Genetics and DNA, writer Mark Schultz and artists Zander and Kevin Cannon attempt to construct a comprehensive primer that not only explains each component and how each process works, but to make sure they come together into a complete picture, better to ensure a true understanding of the subjects rather than a disconnected series of facts. They do this by wrapping it up in a science fiction framework, taking us to the the distant planet of Glargal. There, the sea-cucumber-like invertebrate Squinch have fallen upon hard times; an unspecified genetic disorder is starting to affect the asexual populace, and their best scientists have been tasked with finding out why.

New ‘Critically Sensitive’ Technology Providing Potential for Broad Range of Scientific Discovery | CFAES. COLUMBUS, Ohio -- Ohio State University researchers are investigating the benefits of using a new analytical platform in the emerging field of metabolomics.

Experts say the platform has the potential to open doors for new discoveries in disease prevention and treatment as well as a wide range of innovative scientific projects involving foods, plants, animals and humans. “Metabolomics involves analytical techniques to monitor all organic compounds, particularly metabolites, present in a cell—plant, animal or human,” said Steven Schwartz, professor of food science and technology in Ohio State’s College of Food, Agricultural, and Environmental Sciences (CFAES) and member of the molecular carcinogenesis and chemoprevention research program at the OSU Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC-James). Metabolomics in Ohio State Research Other researchers, including Dr.

The bacteria that changed the world - May, 2017 The make-up of Earth's atmosphere, once the domain of Earth science textbooks, has become an increasingly "hot" news topic in recent decades, as we struggle to curb global warming by limiting the carbon dioxide that human activity produces. While the changes that humanity has wrought on the planet are dramatic, this isn’t the first time that one species has changed Earth’s atmosphere. Three billion years ago, there was no free oxygen in the atmosphere at all. Life was anaerobic, meaning that it did not need oxygen to live and grow. That all changed due to the evolution of Cyanobacteria, a group of single-celled, blue-green bacteria.

To start, you may want to watch this video entitled What is STEM Education? What is STEM Education Be sure to visit the Project Noah site before starting the lesson at Before students go out into the field, you should create a mission on the Project Noah site. This should include a brief description of what you'd like students to do,as well as more specific instructions and a timeline for completion of the project.

You may choose to assign the field visits as homework or do them during class time. Even urban areas have ecosystems. “Citizen science”is a term that describes programs in which people who may or may not have scientific training contribute to a project. This lesson can be used to reinforce many different concepts such as the diversity of life, food chains, energy flow through ecosystems, interdependence of living things, dynamic equilibrium, and human interaction with the environment.

A Mini World: Biodomes Engineering Design Project. What is the engineering design process? It is a set of steps that engineers take when designing a new or improved product. It includes: Finding a problem or needComing up with creative ideasSelecting the most promising ideaCommunicating the ideaCreating or building a model of the design, andEvaluating what you have built. The following video provides more information on engineering.

What is Engineering Sample points for Introductory Class Discussion What are environments and ecosystems and why do we need to understand them? Let's imagine that we are traveling through different environments on a mission to collect information about the plants, animals, weather and climate. Do you know what a biodome is? Over the years, creating a successful biodome that achieves balanced plant and animal life has proven to be a major challenge for the scientific and engineering communities. In this lesson, we are going to become engineers who create model ecosystems. Journey to the Redwoods - Environment. A Family Consents to a Medical Gift, 62 Years Later. Biotechnology. Biodiversity. Pesticide Accumulation in Sierra Nevada Frogs (7/26/2013 12:00:00 PM)

SACRAMENTO, Calif. — A study on frogs in remote Sierra Nevada mountain habitats including Yosemite National Park and Giant Sequoia National Monument, detected concentrations of pesticides in frog tissue that potentially came from California's Central Valley sources. "Our results show that current-use pesticides, particularly fungicides, are accumulating in the bodies of Pacific chorus frogs in the Sierra Nevada," says Kelly Smalling, a research hydrologist with the U.S. Geological Survey and lead author of the study. "This is the first time we’ve detected many of these compounds, including fungicides, in the Sierra Nevada.

The data generated by this study support past research on the potential of pesticides to be transported by wind or rain from the Central Valley to the Sierras. " Researchers sampled seven sites across Lassen Volcanic National Park, Lake Tahoe, Yosemite National Park, Stanislaus National Forest and Giant Sequoia National Monument.

Biodiversity refers to all the different kinds of living organisms within a given area and the roles they play in their ecosystems. Biodiversity includes plants, animals, fungi, and other living things—everything from towering redwood trees to tiny insects.

Biodiversity is important to people in many ways. Plants, for instance, help humans by giving off oxygen. They also provide food, shade, shelter, medicines, and fiber for clothing and paper. The root system of plants helps prevent flooding. Biodiversity is especially important to the medical and pharmaceutical industries. Ecosystems with a lot of biodiversity are also stronger and more resistant to disaster than those with fewer species. All species are interconnected.

Mongabay.com November 02, 2012 Click image to enlarge Scientists have created an evolutionary maps for all the world's nearly 10,000 bird species. The 'tree of life' is published in the current issue of the journal Nature. The international team researchers used DNA-sequencing data — when available — to show the evolutionary relationships between living bird species.

It also shows bird speciation rates across time and geographies. "We have built the first ever family tree showing the evolutionary relationship among the species of birds. We used fossils and genetic data to estimate the ages of all the different branches of the bird tree so that we could assess how diversity has accumulated through time," said co-author Gavin Thomas of the University of Sheffield in a statement. "Our work is indebted to researchers from museums and universities who have collected astounding amounts of genetic data from birds around the world.

Ask casual hikers about fallen trees in a forest and they might describe the deadwood as mere arboreal debris, inconvenient and unsightly.

But ask wildlife scientists about the same obstacles and they likely will launch into a lesson laced with metaphors suggesting that a single rotting log is much more than a rotting log. A fallen tree, they will tell you, is a house, a grocery store and a bank all rolled into one. Beneath the peeling bark, termites and lichen digest decades worth of energy; raccoons, woodpeckers and ants carve out dwellings; and the deteriorating wood stores nutrients and keeps carbon dioxide out of the atmosphere.

Without this coarse, woody debris, forests lose the ability to maintain a diverse wildlife, said Peter Curtis, chairman of Ohio State University’s department of evolution, ecology and organismal biology. Simply put, fallen trees are fosterers of life. In fact, experts estimate that more than 50 percent of woodland species depend on them. ryanclark@dispatch.com. The Day the Mesozoic Died.

For more than a month, Tricia and Bryan Mahoney have seen a show play out each evening around sunset. One by one, as many as eight young foxes pop out from under the Mahoneys’ deck and convert their Worthington yard into a prancing playground. Although the animals seem carefree, their presence in the suburban neighborhood — a few blocks west of the city’s downtown — is actually a sign of desperation, say officials of the Ohio Department of Natural Resources. Foxes have been migrating to cities and suburbs to seek shelter from coyotes, which kill their smaller canine cousins because they compete for the same food: mice, chipmunks, rabbits and squirrels.

“Red foxes seem to be spending more time near development and humans, particularly when they are rearing young,” said Suzanne Prange, a wildlife research biologist in ODNR’s Athens office. “I believe this is in response to an increase in coyotes. Such incidents, experts say, are rare. “They have never bothered us in any way.”
