    Nobel Prize in chemistry commends finding and use of green fluorescent protein

    Making cells glow with a protein borrowed from jellyfish is one of the brightest ideas in chemistry. At least that is what the RoyalSwedishAcademy of Sciences implied when it announced October 8 that the 2008 Nobel Prize in chemistry would be awarded to three scientists who were instrumental in discovering green fluorescent protein, commonly called GFP, and developing the protein as a...

    Cooling climate ‘consensus’ of 1970s never was

    The reasons to disbelieve that humans are causing global warming are many and varied, skeptics say. For example: Natural factors such as long-term variations in solar radiation are causing the rise in worldwide average temperature. The urban heat island effect is skewing modern weather data, so the warming observed in recent decades isn’t real. And besides, not long ago experts all believed...

    U.S. must invest in technologies to avoid energy crisis

    Steven Chu, director of Lawrence Berkeley National Laboratory and a Nobel laureate in physics, has advocated for energy thrift. During a September visit to Washington, D.C., he spoke with senior editor Janet Raloff about how he believes the United States can tackle what he sees as a looming energy crisis.

    You’ve said the United States needs to launch an energy research program that’s...

    Body In Mind

    With gargantuan ears, gleaming brown eyes, a fuzzy white muzzle and a squat, furry body, Leonardo looks like a magical creature from a Harry Potter book. He’s actually a robot powered by an innovative set of silicon innards.

    Like a typical 6-year-old child, but unlike standard robots that come preprogrammed with inflexible rules for thinking,...

    Ultramassive: as big as it gets

    If asked to name stupendously amazing things in space, most people would probably pick black holes. These evil-tinged clowns of the universe are definite wows. Insatiable is their middle name.

    Grand and merciless, voracious and monstrous, pure appetite and deep mystery. The biggest fatten themselves in galaxy cores mainly via a seemingly...

    Nobel Prize in physics shared for work that unifies forces of nature

    The 2008 Nobel Prize in physics has been awarded to three theoretical physicists for advances involving the concept of symmetry breaking. The theory highlights how three of the four seemingly disparate forces in nature fall under the same umbrella. The work forms a cornerstone of the standard model of particle physics.

    Half of the $1.4 million prize goes to Yoichiro Nambu of the...

    Charging up fuel injection

    A little voltage can jolt existing cars into getting better gas mileage, new research shows.Applying a strong electric field to fuel a moment before it’s injected into the engine’s cylinders boosted fuel efficiency of a Mercedes-Benz 300D from 32 to 38 miles per gallon during six months of road tests — an increase of more than 18 percent, scientists report in the Nov. 19 Energy & Fuels....

    Bicoastal Atlantic bluefin tuna

    Bluefin tuna get around. The highly prized fish traverse the Atlantic with a disregard for international boundaries that has set nations quarrelling over who gets to fish and who sets the limits. Now new research on the whereabouts of Atlantic bluefins could provide the hard numbers needed for developing effective strategies to save the fisheries from collapse.

    “This is a substantial step...

    Diamonds engage at the nano scale

    The nearly-occult art of quantum computing research could soon help scientists in fields as remote as biology.

    Two teams of researchers from the United States and Germany have found a way to essentially make diamond nanocrystals into microscopes that would see at the resolution of a single molecule. Such resolution could image the structure and motion of single molecules and...
