researchers have found that ordinary conversation creates a conical, “jet-like” airflow that carries a spray of tiny droplets from a speaker’s mouth across meters of an interior space.

Ning Lin, associate professor of civil and environmental engineering, and her research group use computers to whip up virtual hurricanes that help policymakers evaluate the risks of severe storms in regions such as New York City, where such storms are rare but potentially devastating.

Princeton researchers used scanning tunneling microscopy to observe what happens when they add electrons to magic-angle twisted bilayer graphene. They observed a cascade of transitions in the electronic properties, patterns that could help unlock how superconductivity emerge in these materials. Continue Reading →
: Princeton researcher Britt Adamson, together with collaborators, developed improvements to high-throughput technologies that can be used to explore how cells respond to experimentally-induced changes in gene expression. Continue Reading →
Mathematical modeling helps researchers to understand how enzymes in the body work to ensure normal functioning, and how genetic mutations alter the enzymes’ behavior in ways that cause disease, including cancer. Continue Reading →

A new study yields insights into how an organelle called the pyrenoid, which helps algae remove carbon dioxide from the atmosphere, forms inside the cell via a process similar to how oil separates from water. Continue Reading →
As mysterious as the Italian scientist for which it is named, the Majorana particle is one of the most compelling quests in physics. Its fame stems from its strange properties – it is the only Continue Reading →
T cells are like the special ops forces of the immune system, detecting and killing infected cells. When a new threat is detected, the cells ramp up from just a few sentry cells to a Continue Reading →
Princeton University researchers have demonstrated a new way of making controllable “quantum wires” in the presence of a magnetic field, according to a new study published online today in the journal Nature. The researchers detected channels Continue Reading →
By Scott Lyon If you have ever poured hot coffee into a cheap plastic cup, you may recall that sinking feeling as the cup seems to wilt. Not quite solid, not quite liquid, the cup Continue Reading →
By Kevin McElwee Only about 10 percent of the human genome are actually genes. The other 90 percent? Once called “junk DNA,” researchers now know that this genetic material contains on-off switches that can activate Continue Reading →
By Kevin McElwee “When the horns started to blow and we saw the Statue of Liberty, I thought I was in heaven. Really. She’s up there and saying, ‘Come on in. From now on you Continue Reading →
By Yasemin Saplakoglu WE ARE CONCERNED, rightly so, about the amount of carbon dioxide accumulating in the Earth’s atmosphere. But to most plants, which use carbon for photosynthesis, the amount we have is not enough. Continue Reading →
By Yasemin Saplakoglu GETTING A TIRED and hungry 12-year-old to hike another mile up a steep mountain is a daunting task. But John Pardon’s parents quickly figured out a simple solution that saved many of Continue Reading →
By Yasemin Saplakoglu DESPITE THEIR CHARM AND ALLURE, diamonds are rarely perfect. They have tiny defects that, to assistant professor Nathalie de Leon, make them ever so appealing. These atom-sized mistakes have enormous potential in Continue Reading →
By Sharon Adarlo A new solar cell technology could make it inexpensive to create and install smart windows that automatically vary their tint to augment lighting, heating and cooling systems in buildings. The new transparent Continue Reading →
By Pooja Makhijani A new study has identified genetic changes that are linked to dogs’ human-directed social behaviors and suggests there is a common underlying genetic basis for hyper-social behavior in both dogs and humans. Continue Reading →
By Yasemin Saplakoglu We might think we have control of the mix of decisions we make during the day. But it turns out that our brain gives us subconscious nudges, preferring some choices over others. Continue Reading →
By Bennett McIntosh THE COLDEST SPOT on the Princeton campus is a cluster of a few thousand atoms suspended above a table in Waseem Bakr’s laboratory. When trapped in a lattice of intersecting lasers at Continue Reading →
STRIP AWAY ELECTRONS FROM THEIR ATOMS and you get a plasma — a collection of negatively charged electrons and positively charged ions. But at high energies around compact cosmic objects such as black holes, quasars Continue Reading →
ELECTRONS DART within and between atoms far too quickly for current imaging techniques to observe their motion. To capture fast-moving objects without a blur, a photographer can use a camera flash to light up a Continue Reading →
Robert Cava weaves physicists’ dreams into exotic new materials By Bennett McIntosh ROBERT CAVA PULLS A LONG CURVED steel blade from its ornate sheath, revealing a rippling pattern of light and dark metal. The sword Continue Reading →
Innovations in building materials, design, water systems and power grids are helping to make cities more livable, say researchers in Princeton’s School of Engineering and Applied Science By Bennett McIntosh Cities. They sprawl and tangle, Continue Reading →
How the psychology of human behavior is helping tackle society’s biggest problems By Wendy Plump SUPPOSE someone approaches you on the street with the following proposition: You can receive either cash on the spot or Continue Reading →
Some drugs cannot be delivered via a normal pill or injection because they cannot readily dissolve in water. About 40 percent of new pharmaceuticals have this hydrophobic (water-fearing) character, and like a globule of oil Continue Reading →
ON NEW YEAR’S DAY 2015, A BALLOON-BORNE SPACECRAFT ascended above Antarctica and snapped crisp photos of space, unobscured by the humidity of Earth’s atmosphere. Meanwhile, a telescope located 4,000 miles to the north, in the Continue Reading →
