Conservation spending proven to make a difference

The world is currently experiencing its sixth mass extinction event. Species are disappearing at an estimated 1000x the expected normal rate of extinction (roughly 5 species per year). Conservation efforts around the world are trying to reduce the rate of biodiversity loss, but they are hindered by the lack of hard evidence linking conservation spending to biodiversity improvements. A team led by University of Oxford researchers … Continue reading Conservation spending proven to make a difference

Better Bees: Progress Towards Robotic Pollinators

Bees and pollen are associated with a variety of irritations, but together they play a key role in crop production and global agriculture. Unfortunately, bee populations have been declining over the past decade. In response to the threat posed to the world’s food supply, scientists from Japan have been working to develop a robotic bee that can pollinate flowers just like a real honeybee. These … Continue reading Better Bees: Progress Towards Robotic Pollinators

Climate Change Makes the Earth Wobble

In the year 2000, the Earth’s spin axis made a sudden turn towards the east. While some shifts in the geographical pole occur regularly and are well understood, this sudden shift required a new explanation. According to teams from UT Austin and NASA’s Jet Propulsion Laboratory (JPL), climate change is the driving force behind the north pole’s wayward path.   In 2013, the team from … Continue reading Climate Change Makes the Earth Wobble

Why is Antarctica’s Ice Sheet Growing in a Warming World?

by Jordan Wilkerson figures by Michael Gerhardt When someone asks you to consider the impacts of climate change, what do you think of? There’s a good chance that melting ice sheets comes to mind pretty quickly. For that reason, a recent finding regarding the trend in Antarctic ice is quite perplexing; the ice sheet is reportedly increasing in size! This is according to a research … Continue reading Why is Antarctica’s Ice Sheet Growing in a Warming World?

Solid-oxide Fuel Cells: Using familiar fuel in a new way

by Michael R. Gerhardt Our climate is rapidly changing, and many countries are beginning to take action. In the United States, President Barack Obama has announced the Clean Power Plan to reduce greenhouse gas emissions from electric power generation, while Chinese president Xi Jinping has announced economic incentives to reduce emissions [1,2]. Even oil companies have publicly acknowledged the challenges we face and have voiced … Continue reading Solid-oxide Fuel Cells: Using familiar fuel in a new way

The Light of Elendil in Shelob’s Lair

By Andrew Wong, a second year graduate student in the Applied Physics program at Harvard University.       The increase in global energy demand and subsequent carbon dioxide emissions has driven advancements in renewable energy generation technologies such as wind turbines and solar cells. However, these technologies are inherently intermittent, and require robust energy storage devices. Inexpensive, large-scale energy storage systems such as aqueous … Continue reading The Light of Elendil in Shelob’s Lair

Insecticidal Plants: The Tech and Safety of GM Bt Crops

by Matthew Niederhuber figures by Kaitlyn Choi Summary: Bacillus thuringiensis (Bt) is a common bacteria that has played a very uncommon role in agriculture and the development of genetically modified foods. The natural insecticidal abilities of these bacteria have made them an important pest control tool for nearly a century. While their use as a natural biopesticide is widely accepted and approved for organic applications, … Continue reading Insecticidal Plants: The Tech and Safety of GM Bt Crops

Why Roundup Ready Crops Have Lost their Allure

by Jordan Wilkerson figures by Brian Chow Summary: In the history of agriculture, no technology has been adopted so quickly and completely as genetically engineered crops. Particularly useful crops are ones that have an engineered resistance to herbicides. These crops have alluring benefits: reduced crop damage when herbicides are sprayed, easier weed management, and even the potential for environmental benefits. So what’s the problem? Herbicide-resistant … Continue reading Why Roundup Ready Crops Have Lost their Allure

Memoirs of a Toxin: The lasting human impact on mercury in the environment

Presented by Hannah Horowitz Mercury is a potent neurotoxin. For thousands of years, humans have altered mercury cycling in the environment by introducing massive amounts of mercury to surface water, soils, and air, through mining and burning coal. Once in the surface environment, mercury can threaten human and wildlife health, is transported globally through the air, and continues to have an impact for hundreds of … Continue reading Memoirs of a Toxin: The lasting human impact on mercury in the environment

Understanding sea level change by diving into the past

Presented by Jacky Austermann Why does sea level change? Everyone knows that sea level rise is a threat to coastal cities, but the mechanisms of why the change happens are less often talked about. In my talk I will explain why sea level is changing, why it is changing at different rates around the globe, how we can use the measured sea level rise to … Continue reading Understanding sea level change by diving into the past
