A new study by Harvard scientists suggests that, from a young age, children are biased in favor of their own social groups when they intervene in what they believe are unfair situations. But as they get older, they can learn to become more impartial.
A new study sheds light on the extent to which animals can make distinctions among scents.
Using genetic tools to implant genes that produce fluorescent proteins in the DNA of transparent C. elegans worms, Harvard scientists have been able to shed light on neuron-specific “alternative splicing,” a process that allows a single gene to produce many different proteins.

Bauer Fellow Rachel Dutton has identified three general types of microbial communities that live on cheese, opening the door to using each as a “model” community for the study of whether and how various microbes and fungi compete or cooperate as they form communities, as well as what molecules and mechanisms are involved in the process.
The largest-ever phylogenetic spider study shows that, contrary to popular opinion, the two groups of spiders that weave orb-shaped webs do not share a single origin.
A new technique for observing neural activity will allow scientists to stimulate neurons and observe their firing pattern in real time.

A new theoretical framework outlined by a Harvard scientist could help solve the mystery of how bacterial cells coordinate processes that are critical to cellular division, such as DNA replication, and how bacteria know when to divide.
Heat is a byproduct of nearly all electronic devices, yet most of it goes wasted. In an effort to recapture some of that energy and transform it into electricity, a team of Harvard and University of Sannio researchers have developed computer simulations to control the flow of heat and electrical current independently.
A study by Harvard researchers and colleagues tested ways to encourage decisions mindful of future generations.
Their scholarly interests range from the design of programming languages to health economics to the molecular changes that influence evolutionary fitness.

Harvard physicists have suggested that a disk of dark matter may lie along the center line of the galaxy.
A team of Harvard researchers has demonstrated that a shared developmental mechanism in songbirds is responsible for generating tremendous variability in their beaks, and is also a control on what kind variation can be produced.
Harvard is immersed in understanding the world and improving it. Here’s how the University is making a difference now, and likely will do so in the next decade, in five key fields.
Harvard scientists have discovered a compound that inhibits insulin-degrading enzyme from breaking down insulin in the body.
It could be that the key to being a better parent is all in your head, Harvard researchers say.
Harvard researchers have succeeded in creating quantum switches that can be turned on and off using a single photon, an achievement that could pave the way for the creation of highly secure quantum networks.
Professor Michael McCormick will lead a project aimed at constructing the most detailed historical record yet of European climate.
Donors and students recently gathered for the Celebration of Scholarships dinner, an annual event that brings together students who benefit from financial aid with donors who support the program.
A team of scientists led by Professor of Physics and of Applied Physics Amir Yacoby has developed a magnetic resonance imaging (MRI) system that can produce nanoscale images, and may one day allow researchers to peer into the atomic structure of individual molecules.
Matthew Rabin wants to know what makes you tick. One of the nation’s top scholars of behavioral economics, Rabin has been appointed to the first of ...
For most people, rock-paper-scissors is a game used to settle disputes on the playground. For biologists, however, it is a powerful guide for understanding ...
A new study from Dartmouth and Harvard researchers looks at the mechanisms behind facial recognition.
In an effort to dispel the notion that graduate school and careers in academia are generally beyond the reach of minority students, Harvard hosted the second Ivy Plus Symposium.
New research conducted at Harvard demonstrates sharing behavior in African grey parrots.
A team of Harvard researchers has demonstrated that the bacterium Rhodopseudomonas palustris can use natural conductivity to pull electrons from minerals located remotely in soil and sediment while remaining at the surface, where it absorbs the sunlight needed to produce energy.
Scientists have long suggested that the best way to settle the debate about how phenotypic plasticity may be connected to evolution would be to identify a mechanism that controls both. Harvard researchers say they have discovered just such a mechanism in insulin signaling in fruit flies.
Female academics are less likely to collaborate across rank, a Harvard study found.
New Harvard research points to a sharper method for evaluating basketball players.
In the Instructional Physics/SEAS Instrument Lab, a machine shop tucked in the basement of Lyman Laboratory, students learn to use a range of equipment — everything from lathes to laser cutters to 3-D printers.
Led by Professor David Liu, a team of researchers has developed a technique to continuously evolve biomolecules that uses negative selection — the ability to drive evolution away from certain traits — to create molecules with dramatically altered properties.
A new study has uncovered a previously unseen phenomenon — that curved surfaces can dramatically alter the shape of crystals as they form.
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.
A new study offers the first evidence that fetal sex can affect the amount of milk cows produce, a finding that could have major economic implications for dairy farmers.
Scientists at Harvard have identified a previously unknown embryonic signal, dubbed Toddler, that instructs cells to move and reorganize themselves, through a process known as gastrulation, into three layers.
January@GSAS offered more than 100 classes, seminars, and training sessions to students in Harvard’s Graduate School of Arts and Sciences during semester break. Students had the chance to escape the lab or library, and spend time exploring subjects that might not otherwise appear in a Harvard course catalog.
Though variability is often portrayed as a flaw to be overcome, Harvard researchers now say that, in motor function, it is a key feature of the nervous system that helps promote better or more successful ways to perform a particular action.
Harvard scientists say they’re closer to unraveling one of the most basic questions in neuroscience — how the brain encodes likes and dislikes — with the discovery of the first receptors in any species evolved to detect cadaverine and putrescine, two of the chemical byproducts responsible for the distinctive — and to most creatures repulsive — smell of rotting flesh.
New research brings scientists closer to unraveling one of the longest-standing questions in evolutionary biology — whether limbs, particularly hind limbs, evolved before or after early vertebrates left the oceans for life on land.
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 new Harvard study shows that, in as little as a day, diet can alter the population of microbes in the gut – particularly those that tolerate bile - as well as the types of genes expressed by gut bacteria.

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.
