Professors Newman and Orphan Named MacArthur Fellows

09-21-16

Environmental Science and Engineering Professors Dianne Newman and Victoria Orphan have been selected as 2016 MacArthur Fellows. Professor Newman's research focuses on microbial stress responses, with an emphasis on mechanisms of energy generation and survival when oxygen is scarce. Professor Orphan studies the molecular microbial ecology of anaerobic communities with a particular focus on microorganisms that live in deep-ocean sediment beds and consume large quantities of methane released from seeps in the ocean floor.

122nd Commencement Ceremony

06-10-16

Caltech’s 122nd commencement ceremony was held on Friday June 10, 2016. The commencement speaker was surgeon, writer, and public health researcher Atul Gawande, MD, MPH. He reminded the graduates that, “today, you become part of the scientific community, arguably the most powerful collective enterprise in human history. In doing so, you also inherit a role in explaining it and helping it reclaim territory of trust at a time when that territory has been shrinking.” He also cautioned them and explained, “the mistake … is to believe that the educational credentials you get today give you any special authority on truth. What you have gained is far more important: an understanding of what real truth-seeking looks like. It is the effort not of a single person but of a group of people—the bigger the better—pursuing ideas with curiosity, inquisitiveness, openness, and discipline.” [The Mistrust of Science]

Aliso Canyon, Methane, and Global Climate

04-18-16

The Aliso Canyon underground storage facility for natural gas in the San Fernando Valley—the fourth largest of its kind in the United States—had one of its wells blow out on October 23, 2015, leading to a large release of methane. In a recent conversation, Professor Paul Wennberg discusses enormous methane and carbon dioxide (CO2) emissions, and their troubling implications for global climate. “If we could really knock the methane emissions back to what they were before people started emitting methane, it would be a large change. It would be a half a watt per meter squared. The total global warming would drop by around 25 percent,” Professor Wennberg explains. [Caltech story]

ENGenious Wins Gold!

02-25-16

The 2015 issue of ENGenious has won a gold award from the Council for Advancement and Support of Education (CASE) District VII in the Awards of Excellence category of Annual Magazines. The award is given by the CASE District VII Board of Directors and the Awards of Excellence Committee to "superior magazines published once a year." First published in 2001, ENGenious is a publication for alumni and friends of the Caltech Division of Engineering and Applied Science (EAS). The goal of the publication is to highlight the contributions of the EAS faculty, students, and alumni in research, education, and industry. [ENGenious]

Sisca

Solar Powered, Electrochemical, Wastewater Treatment System

12-18-15

Cody Finke, Environmental Science and Engineering graduate student, and Justin Jasper, Resnick Sustainability Institute Prize Postdoctoral Scholar, are the runner ups for the Dow Resnick Sustainability Innovation Student Challenge Award (SISCA) at Caltech. They have been working Professor Michael Hoffmann to enhance a modular, solar powered, electrochemical, on-site wastewater treatment system created by their group for toilets in the developing and developed world. With an operating cost of less than 5 US cents per day, this wastewater treatment technology meets benchmarks for affordability in the developing world. It also has the potential to protect human health and ecosystem well-being in communities most at risk to disease and resource-loss through environmental pollution. [Resnick Institute story]

Extending a Battery's Lifetime with Heat

10-03-15

The research of alumnus Asghar Aryanfar (’15 PhD, ME) along with Professors Goddard and Hoffmann has shown that heat can break down the damaging branch-like structures that grow inside batteries, which may possibly be used to extend battery lifetimes. [Learn more] [Read the paper]

121st Commencement Ceremony

06-12-15

Caltech’s 121st commencement ceremony was held on Friday June 12, 2015. The commencement speaker was cultural anthropologist Genevieve Bell, an expert on the intersection of culture and technology. She reminded the graduates that it is the 50th anniversary of Moore’s Law which she referred to as a bold statement of engineering and a promise about the state of the future. She asked the graduates to not only bring their technical skills to the table, but also their humanity and obligation to make the work a better place. [View Dr. Bell’s commencement address]

A Winning Sanitation Solution

06-11-15

The inventors of the solar-powered toilet, a unit developed by a team led by Professor Michael Hoffmann, have a new award winning project. Project Seva, which means "service" in Hindi. It was named the first place winner of the Vodafone's Wireless Innovation program. The Seva team realized that because the solar toilet and other sanitation systems like it are relatively simple, inexpensive sensors could be used to monitor the status of those systems' parts. Combining that insight with the knowledge that more than three-quarters of the world's people have access to a mobile phone, the team decided to design a self-diagnosing maintenance system for sanitation solutions that could alert designated local operators of a malfunction via cell phone message.

Tracking Photosynthesis from Space

05-04-15

Professor Paul Wennberg and colleagues have developed a new technique to analyze plant productivity using data from NASA's Orbiting Carbon Observatory-2 (OCO-2) satellite. To perform photosynthesis, the chlorophyll in leaves absorbs sunlight and a small fraction of the absorbed light is reemitted as near-infrared light. This reemitted light makes the plants appear to glow—a property called solar induced fluorescence (SIF). "The measurements of SIF from OCO-2 greatly extend the science of this mission", says Professor Wennberg. "OCO-2 was designed to map carbon dioxide, and scientists plan to use these measurements to determine the underlying sources and sinks of this important gas. The new SIF measurements will allow us to diagnose the efficiency of the plants—a key component of the sinks of carbon dioxide." [Caltech story]
