Theoretical physicist Lawrence Krauss described a universe with mysterious particles popping in and out of existence, in which the discoveries of dark energy and dark matter have made mankind more insignificant than ever.

New research out of the Harvard Forest offers insight on exactly when the tipping point occurs that can disrupt the intricate web of life in a lake.

The rise of the middle class is a bigger environmental challenge than the rising global population, according to Sir David King, the former science adviser to the British government, who urged the adoption of sustainable development as a way to manage growing global demands in a finite world.

Astronomers have found a planetary system orbiting the star Kepler-62. This five-planet system has two worlds in the habitable zone — the distance from their star at which they receive enough light and warmth for liquid water to theoretically exist on their surfaces.

Two communications specialists at the Chandra X-Ray Observatory have authored a guide to the universe, aiming to show people around a universe they say belongs to us all.

Harvard researchers are adding nuance to our understanding of how modern and historical temperatures compare.

Harvard astronomers past and present gathered in Cambridge Friday (April 5) for the first-ever reunion of the Harvard Astronomy Department.

Andrew Ho, research director of HarvardX and an assistant professor at the Harvard Graduate School of Education, spoke with the Gazette about a recent study that found that interspersing online lectures with short tests improved student performance.

A gerontologist researcher says his work allows him to connect with “vibrant, engaged, healthy, exciting, and active older people.” He says they live more in the now than other people might believe, and value that.

By interspersing online lectures with short tests, student mind-wandering decreased by half, note-taking tripled, and overall retention of the material improved, said Daniel Schacter, the William R. Kenan Jr. Professor of Psychology, and Karl Szpunar, a postdoctoral fellow in psychology.

Scientists may soon be able to turn to one of the most powerful forces in biology — evolution — to help in their quest to develop new synthetic polymers.

In a question-and-answer session, Harvard astronomy chair Avi Loeb explains the new data from the European Space Agency’s Planck satellite.

A lecturer from the Harvard-Smithsonian Center for Astrophysics says that “dark clouds of gas and dust have the potential to alter Earth’s climate.

In a breakthrough that could one day yield important clues about the nature of matter itself, a team of Harvard scientists has measured the magnetic charge of single particles of matter and antimatter with unprecedented precision.

In “Sidetracked: Why Our Decisions Get Derailed, and How We Can Stick to the Plan,” Francesca Gino, an associate professor at Harvard Business School, explores a range of fascinating subjects, including how emotions influence decisions and the often-thorny matter of understanding the perspectives of others. Blending social science and real-world examples, Gino’s book also highlights the science of gratitude.

With the world’s sea levels rising and posing a long-term threat to coastal cities, Nigerian architect Kunlé Adeyemi suggests building houses that float, but, taken together, still function as a community.

Stamping Harvard’s digital presence on the South by Southwest Interactive Festival, more than 250 alumni, students, faculty, and guests convened on Icenhauer’s for the second annual Digital Harvard in Austin at SXSW, hosted by the Harvard Alumni Association.

The Temple of Amun-Ra at Karnak isn’t the most famous ancient site in Egypt — that honor goes to the Pyramids at Giza — but newly developed reconstructions using 3-D virtual reality modeling make clear its architectural importance and rich history.

In online education, the future is now. That was an overriding message Harvard and MIT hosted a summit on March 3 and 4 titled “Online Learning and the Future of Residential Education.”

Three Harvard affiliates are launching Zeega, a software platform that makes it easy for Internet storytellers to blend audio, images, and text from the riches of the Web.

Scholars convened at the Harvard Graduate School of Education to explore the topic of bullying and potential ways forward.

Harvard’s Avi Loeb is helping prepare the next generation of astronomers with a new textbook, “The First Galaxies in the Universe.”

Harvard psychologist Mahzarin Banaji and longtime collaborator Anthony Greenwald condense three decades of work on the unconscious mind in “Blindspot: Hidden Biases of Good People.”

There may be a formula for happiness after all, says Daniel Gilbert, Harvard professor of psychology and best-selling author of “Stumbling on Happiness,” who presented an impressive array of scientific research from the disciplines of economics, psychology, and neuroscience to assess his mother’s recipe for happiness.

A report co-authored by Professor Michael McElroy and D. James Baker, a former administrator of the National Oceanic and Atmospheric Administration, connects global climate change, extreme weather, and national security.

Harvard President Drew Faust called for the scientific community to unite in its efforts to press Congress for continued federal research support during a speech to the annual meeting of the American Association for the Advancement of Science.

More vigorous grassroots social action is needed to drive the reforms that could address climate change, panelists said during a discussion at Sanders Theatre.

Using small explosions produced by a mix of methane and oxygen, researchers at Harvard have designed a soft robot that can leap as much as a foot in the air.

Using small explosions produced by a mix of methane and oxygen, researchers at Harvard have designed a soft robot that can leap as much as a foot in the air. That ability to jump could one day prove critical in allowing the robots to avoid obstacles during search and rescue operations.

As research funding dwindles, scientists need to rethink their methods for supporting the most promising projects, and how they communicate their work to the public, Nobel Prize–winning geneticist Paul Nurse told an audience of Harvard scientists.
