Roots, Shoots and a Dash of Medicine

Cornell is a gold mine of fantastic gardens, beautiful foliage and abundant flora. In just the five-minute walk from Mann Library to Rockefeller Hall, one can see trees of all sizes and a wide variety of flowers. With colorful flower blossoms in spring and large full trees in summer, the valley, campus walkways and gardens are scenic masterpieces for much of the year. But there is much more to these shrubs, leaves or grasses than meets the eye. Cancer, Alzheimer’s and Diabetes are all debilitating diseases.

Turning the Clock Back: Mechanisms of Aging

Studies in evolutionary biology tell us that all living organisms originated from a common ancestor, yet lifespans vary greatly. Clearly, something in the genome accounts for such stark differences; the question is what? Why do we live as long as we do? Why do our bodies break down as we age? On March 6, Prof. Vadim Gladyshev, medicine, Harvard, led a seminar at Cornell titled “Mechanisms of Aging and Redox Control” that attempted to answer some of these questions.

Cornell Professor Advocates for Access to Choose Genetically Modified Crops

On a list of the most controversial topics in science, genetically modified organisms would easily be close to the top. Concerns about their safety and effect on naturally bred species continue to dominate scientific and policy discussions. Prof. Sarah Davidson Evanega, plant breeding and genetics, however, is assured of their safety and maintains that they could play an important role in fighting global food insecurity. Speaking at the Food Security and Global Growth: The Big Picture conference on March 4, Evanega detailed the manner in which climate change threatens global food security, emphasizing the ramifications for farmers. “A Tanzanian farmer, Selma, that our team spoke to, spent $300 — half of her annual income — on preparing and planting her two acre maize field.

On Ethics, Fake News and Science

Science is not about standalone discoveries. Scientists share hypotheses, findings and conclusions to help build a concrete picture of the world. To enable such discussion and deliberate science’s role in shaping public policy, the American Association for the Advancement of Science held its annual conference on Feb. 16 in Boston. The theme this year was ‘serving society through science policy.’

Discussions such as these run the risk of harboring a political slant.

Coral bleaching in Maldives, similar to that in the Great Barrier Reef.

Wanted: Great Barrier Reef, Alive

In October 2016, an article began circulating social media outlets with the headline “Obituary: Great Barrier Reef (25 Million BC-2016),” announcing the abrupt death of one of the most diverse and complex ecosystems in the world. Understandably, ecologists and nature enthusiasts alike cried out in alarm. The pinnacle of environmental beauty that had made it into every introductory ecology textbook had passed away, another casualty to the seemingly unstoppable force of climate change. There is no doubt that action needs to be taken immediately if humans ever hope to impede the potentially disastrous effects of climate change, however those who use the recently ‘deceased’ Great Barrier Reef as their first piece of evidence are missing one critical detail. “The Great Barrier Reef definitely sustained some of the biggest impacts its seen from warming events, but it’s definitely not dead,” said Prof. Drew Harvell, ecology and evolutionary biology.

Cornell Astronomical Society Members Analyze NASA’s Exoplanet Discovery

If planet hopping is your notion of a relaxing vacation, then a recent NASA discovery may be for you. On Feb. 22, NASA announced that it had found seven earth-size planets orbiting a single star in the constellation Aquarius. Scientists named this exoplanet system TRAPPIST-1, for the Transiting Planets and Planetesimals Small Telescope they used to make the discovery. Located at a miserly distance of 40 light years from Earth, TRAPPIST-1 includes three planets located in the ‘goldilocks’ zone, within the distance range for liquid water to exist.

Cautious: Cornell Professors Comment on Trump’s Climate Change Policies

While Punxsutawney Phil predicted six more weeks of winter on Feb. 2, the nation had been experiencing one of the warmest months in decades. The United States Geological Survey has attributed the early advent of spring to the result of climate change. The Trump Administration, however, has no plans of taking this threat seriously. President Trump has famously tweeted that climate change is a hoax perpetuated by the Chinese and the recent reports of increasing federal budget cuts to the Environmental Protection Agency have been met with concerns.

Computer Science Colloquium: Do Machines See What I See?

In under 60 years, computer programming has gone from excruciately producing punch cards to instantly creating algorithms that can recognize people in photos. What lies ahead? At Cornell’s weekly computer science colloquium Philip Isola, a postdoc in the electrical engineering and computer sciences department at UC Berkeley, attempted to shed light on that very topic. “My goal is to make systems that can understand the visual world and see the same kind of richness and structure that we see. So, in the talk I was trying to convey one approach to that: learning without having expert knowledge of what you are trying to imitate,” Isola said.

Quantifying Atmospheric Carbon With Soil Microbes

In fall of 1991, eight men and women were sent to live in a three-acre glass and steel dome in the middle of Arizona’s scorching desert. Referred to as Biosphere II, the complex aimed to model the Earth’s biosphere — even containing a field to grow crops. The two year experiment was designed to test if humans were capable of surviving in an artificial ecosystem. Less than a year later, the project lay abandoned. The level of oxygen dropped drastically to levels seen on Mount Everest.
