Science & Tech

Originally scheduled to operate on the Red Planet’s surface for 90 Martian days, the rover Opportunity has now logged more than 3,500 days, traveled nearly 39 kilometers, and collected a trove of data that scientists have used to study the planet’s early history, particularly any past traces of water.

In a new study, Harvard researchers find that inclusive fitness — for decades a standard tool in understanding how altruism evolved — often leads to incorrect conclusions.

In making the most precise measurements ever of the shape of electrons, Harvard and Yale scientists have raised serious doubts about several popular theories of what lies beyond the Higgs boson.

A team of Harvard scientists and engineers has demonstrated a new type of battery that could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and sun far more economical and reliable.

From the violence of Jupiter’s Great Red Spot to Earth’s own extreme weather, Ziff Environmental Fellow Pedram Hassanzadeh is investigating atmospheric vortices, those swirling air masses that make the weather go — and sometimes make it stop.

A new book by the Harvard China Project examines air pollution and greenhouse gas emissions in the world’s largest nation, and uses both science and economics to propose possible solutions.

Harvard Forest researchers, together with state officials and representatives of conservation groups, are proposing a Massachusetts forest plan that increases both conservation and logging, while carefully focusing development to conserve as many large tracts as possible.

Though it has been embraced by everyone from advocates for arts education to parents hoping to encourage their kids to stick with piano lessons, two new studies conducted by Harvard researchers show no effect of music training on the cognitive abilities of young children.

With some predicting the demise of the smartphone, Professor Woodward Yang spoke to the Gazette about near and far prospects in personal tech.

From a “Bad Basketball” fantasy league to software that helps partygoers communicate with DJs, students at Harvard’s introductory computer science course created a wide array of programs on display during the annual fair.

A new study by researchers at the Harvard-Smithsonian Center for Astrophysics shows that students grasp the unimaginable emptiness of space more effectively when they use iPads to explore 3-D simulations of the universe, compared with traditional classroom instruction.

Harvard engineering Professor Robert Wood lends his perspective to Amazon’s proposal to start a flying drone delivery service within a few years. His verdict is that FAA regulations and liability concerns will likely be bigger hurdles than the technology.

Harvard faculty and graduate students lectured, organized, and moderated in big ways throughout a four-day annual meeting in Boston of the History of Science Society.

Emissions of methane from fossil fuel extraction and refining activities in the United States are nearly five times higher than previous estimates, according to researchers at Harvard University and seven other institutions.

Professor Joshua Greene talks about his new book, “Moral Tribes: Emotion, Reason, and the Gap Between Us and Them.” What makes an issue like abortion or Israeli-Palestinian relations seem insurmountable, he said, can be chalked up, in part, to brain wiring.

The Google Glass and Warrior Web projects highlight the annual Radcliffe Science Symposium, which focused on the integration of technology with “smart clothes.”

Representatives from some 195 nations have converged on Warsaw this week for a two-week meeting focused on climate change expected to lay the groundwork for the next international climate agreement. The Gazette spoke with climate policy expert Robert Stavins of the Kennedy School to understand what’s expected from the session.

Chef Joanne Chang ’91 returned to campus to delve into the basis of sweets as part of the “Science and Cooking” lecture series.

When Kathy Ku ’13 proposed to build a water-filter factory in Uganda for $15,000 last year, her contacts advised her to double her budget. If all goes to plan, by next August Ku and her classmates will have created a fully functional and self-sustaining water-filter factory, supplying clean water at half the cost of imported filters.

Kepler-78b is a planet that shouldn’t exist. “This planet is a complete mystery,” said astronomer David Latham of the Harvard-Smithsonian Center for Astrophysics (CfA). “We don’t know how it formed or how it got to where it is today. What we do know is that it’s not going to last forever.”

Scholars on opposite sides of geoengineering debated the climate change strategy’s potential — pitfalls and benefits — this week at the Science Center.

Radcliffe Fellow Tadashi Tokieda is creating and using simple toys whose sometimes surprising behavior both illustrates scientific concepts and causes even experienced scientists to scratch their heads trying to figure out what’s happening.

Clean economic growth is not just a pipe dream — it happened in Ireland between 1990 and 2010, when emissions dropped 10 percent even as the country’s economy grew 265 percent, the leader of that country’s Green Party said in a Harvard talk.

Jon Kabat-Zinn, a professor of medicine emeritus at the University of Massachusetts Medical School and a pioneer in applying mindfulness to the field of medicine, discussed how the concept can be integrated into K-12 education.
