    Phil Baran finds simple recipes for complex molecules

    Phil Baran, 39ChemistScripps Research Institute

    This is not chemist Phil Baran’s first rodeo: It’s clear that he has done media interviews before. In his Scripps Research Institute office perched above a golf course along the Pacific Ocean in La Jolla, Calif., he is at ease, helpful and patient answering basic questions — why is it important to develop a new way to make a carbon-carbon bond? —...

    Qian Chen makes matter come alive

    Qian Chen, 30Materials scientistUniversity of Illinois

    In a darkened room, bathed in the glow of green light, materials scientist Qian Chen watches gold nanorods dance. They wiggle across a computer screen displaying real-time video from a gigantic microscope — a tall, beige tube about as wide as a telephone pole.

    Chen has observed these and other minuscule specks of matter...

    Tenio Popmintchev fits X-ray laser on a tabletop

    Tenio Popmintchev, 39Laser physicistUniversity of Colorado Boulder

    Experimental physics is not for the fainthearted. One tiny error — or a concatenation of many — can keep a complicated experiment from working smoothly. Fortunately, Tenio Popmintchev has the tenacity for it.

    Popmintchev, a laser physicist at the JILA institute at the University of Colorado Boulder, thinks nothing...

    Taming photons, electrons paves way for quantum internet

    WASHINGTON — A quantum internet could one day allow ultrasecure communications worldwide — but first, scientists must learn to tame unruly quantum particles such as electrons and photons. Several new developments in quantum technology, discussed at a recent meeting, have brought scientists closer to such mastery. Scientists are now teleporting particles’ properties across cities, satellite...

    Oldest indigo-dyed fabric found

    Ancient South Americans made blue fabrics to dye for. A piece of approximately 6,000-year-old woven cotton material from Peru gets its blue hue from indigo dye, making it the oldest known example of the colorfast dye’s use anywhere, researchers find.

    Until now, the earliest indigo-dyed fabrics dated to around 4,400 years ago in Egypt and about 3,000 years ago in what’s now western China...

    Where the young hot Earth cached its gold

    There’s a new twist to the story of how Earth’s most precious metals, including gold and platinum, got to where they are in the planet.

    Some 4.6 billion years ago, space rocks pummeling the infant Earth kept it hot and molten. As the nascent planet grew bigger, a new study suggests, the heat and pressure kept precious metals trapped within its upper layers rather than allowing them to...

    Black hole app lets you blow up stars

    If you have an appetite for cosmic destruction, there’s an app for that.

    NOVA Black Holes, a free iPad game developed by the PBS series NOVA, lets you hurl a star at other celestial objects while navigating an increasingly complex minefield of stars, planets and black holes. Each level presents a new target and a fresh landscape of obstacles. And unlike real stars — whose fates are...

    FDA bans chemicals in antibacterial soaps

    As of today, antibacterial soaps have a short shelf life. The U.S. Food and Drug Administration has banned soap products containing 19 active ingredients, including the notorious chemical triclosan, marketed as antiseptics.

    While the term “antibacterial” suggests to consumers that such soaps prevent the spread of germs, evidence suggests otherwise. After asking companies to submit data...

    High-tech cloth could make summer days a breeze

    Plastic cling wrap with nano-sized pores could give “cool clothes” a new meaning.

    The material lets heat escape, instead of trapping it like traditional fabrics, Stanford University materials scientist Yi Cui and colleagues report in the Sept. 2 Science. It could help people keep cool in hot weather, Cui says, and even save energy by reducing the use of air conditioning.

    “It’s a...

    Bacteria-sized molecules created in lab

    Scientists have created giant molecules — the size of bacteria — that may be useful in future quantum computers.

    The molecules of unusual size are formed from pairs of Rydberg atoms — atoms with an electron that has been boosted into a high-energy state. Such electrons orbit far from their atom’s nucleus and, as a result, can feel the influence of faraway atoms.

    To create the...
