Researchers compile dictionary of vocalizations suggesting the animals use equivalent of word compounds, phrasings to communicate complex social situations
A team of experts in mechanics, materials science, and tissue engineering at Harvard has created an extremely stretchy and tough gel that may suggest a new method for replacing damaged cartilage in human joints.
Chef-mixologist Dave Arnold and kitchen science author Harold McGee kicked off the third season of the “Science and Cooking” lecture series, looking at both the history and versatility of food.
Harvard researchers, captivated by a strange coiling behavior in the grasping tendrils of the cucumber plant, have characterized a new type of spring that is soft when pulled gently and stiff when pulled strongly.
Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses.
For the first time, Harvard scientists have created a type of cyborg tissue by embedding a 3-D network of functional, biocompatible, nanoscale wires into engineered human tissues.
Baby songbirds learn to sing by imitation, just as human babies do. So researchers at Harvard and Utrecht University, in the Netherlands, have been studying the brains of zebra finches — red-beaked, white-breasted songbirds — for clues to how young birds and human infants learn vocalization on a neuronal level.
A tool rarely used to understand the impact of pollution on the natural world is evolution, an oversight that an environmental toxicologist says is robbing investigators of important information.
Researchers have developed a system — inspired by nature — that allows soft robots to either camouflage themselves against a background, or to make bold color displays. Such a “dynamic coloration” system could one day have a host of uses, ranging from helping doctors plan complex surgeries to acting as a visual marker to help search crews following a disaster.
Having already broken new ground in robotics with the development, last year, of a class of “soft”, silicone-based robots based on creatures like squid and octopi, Harvard scientists are now working to create systems that would allow the robots to camouflage themselves, or stand out in their environment.
Scientists at the Harvard-Smithsonian Center for Astrophysics and their colleagues at the Heidelberg Institute for Theoretical Studies have made it possible to build a universe from scratch.
It happens to all of us: We think we learned of the Sept. 11 attacks from a radio report, when, in fact, the news came from a co-worker; we’re sure the robber running from the bank was tall, when actually he was short; we remember waking up at 7 yesterday, when 8 is closer to the truth. Such “false memories,” unavoidable in everyday life, can have disastrous consequences in courtrooms and other settings where exactitude matters.
A group of graphics experts led by computer scientists at Harvard have created an add-on software tool that translates video game characters — or any other three-dimensional animations — into fully articulated action figures, with the help of a 3-D printer.
A Harvard Summer School class spurs learning through food, by examining how microbes — bacteria and fungi — can help as well as harm when they get into food, doing much of the work preparing cheeses, beer, soy sauce, and even chocolate.
Researchers at Harvard University and the University of British Columbia (UBC) have provided visual evidence that atmospheric particles — which are ubiquitous, especially above densely populated areas — separate into distinct chemical compositions during their life cycle.
A team of researchers led by James G. Anderson, the Philip S. Weld Professor of Atmospheric Chemistry, warns that a newly discovered connection between climate change and depletion of the ozone layer over the U.S. could allow more damaging ultraviolet (UV) radiation to reach the Earth’s surface, leading to increased incidence of skin cancer.
Harvard physicists say they have unlocked the chemical secret that controls the “fool’s gold” of superconductivity, a “pseudogap” phase that mimics, but doesn’t have all the advantageous properties of, superconductivity.
Research led by scientists at Harvard and University College London has shown that Native Americans arrived in three waves of migration, not one, as is commonly held and that at least one group returned home to Asia.
A team led by Harvard computer scientists, including two undergraduate students, has developed a new tool that could lead to increased security and enhanced performance for commonly used Web and mobile applications.
Harvard’s Wyss Institute for Biologically Inspired Engineering announced that it has received a $2.6 million contract from the Defense Advanced Research Projects Agency (DARPA) to develop a smart suit that helps improve physical endurance for soldiers in the field.
Rhythm research has implications for both audio engineering and neural clocks, said Holger Hennig, a postdoctoral fellow in the laboratory of Eric Heller in the Physics Department at Harvard, and first author of a study of the Ghanaian and other drummers in the journal Physics Today.
Harvard-led researchers have discovered that an Ascomycete fungus that is common in polluted water produces environmentally important minerals during asexual reproduction.
For decades, it has been the holy grail of particle physics, an elusive subatomic particle that offered the tantalizing possibility of explaining how much of the universe works. Billions of dollars have been spent in the search for it. Thousands of researchers — including dozens from Harvard — have conducted trillions of experiments as part of the hunt for its telltale signature.
Atmospheric scientists at the Harvard School of Engineering and Applied Sciences (SEAS) and Nanjing University have produced the first “bottom-up” estimates of China’s carbon dioxide (CO2) emissions, for 2005 to 2009, and the first statistically rigorous estimates of the uncertainties surrounding China’s CO2 emissions.
Using a pair of impurities in ultra-pure, laboratory-grown diamonds, researchers have created room-temperature quantum bits and have stored information in them for nearly two seconds — an increase of nearly six orders of magnitude over the life span of earlier systems. The work, described in the June 8 issue of Science, is a critical first step in the eventual construction of a functional quantum computer, as well as a host of other potential applications.
A new exhibition at the Peabody Museum of Archaeology and Ethnology traces the development of photography and its use in anthropology from the beginnings of both fields in the 1800s to the present.
Materials scientists at Harvard have demonstrated that a solid-oxide fuel cell (SOFC), which converts hydrogen into electricity, can also store electrochemical energy like a battery. This fuel cell can continue to produce power for a short time after its fuel has run out.
In a paper published in the June 7 issue of Nature, Associate Professor Sujoy Mukhopadhyay presents evidence that the Earth’s deep mantle incorporated gas found in the solar nebula in the first few millions of years of the solar system’s formation.
In a talk at Harvard’s Semitic Museum, archaeologist Robert Mason described the discovery of mysterious rock formations near an ancient monastery in Syria.
