Science in three dimensions: the print revolution

July 5, 2012


Three-dimensional printers are opening up new worlds to research.

Christoph Zollikofer witnessed the first birth of a Neanderthal in the modern age. In his anthropology lab at the University of Zurich, Switzerland, in 2007, the skull of a baby Homo neanderthalensis emerged from a photocopier-sized machine after a 20-hour noisy but painless delivery of whirring motors and spitting plastic.

These days, personal kits go for as little as… read more

Science Makes Sex Obsolete

December 1, 2005

In the Nov. 1, 2004, issue of the Proceedings of the National Academy of Sciences, a team led by Ralph Brinster at the University of Pennsylvania managed to grow mouse “spermatagonial stem cells” in a dish. Also known as SSCs, they are the type of stem cells that eventually become sperm.

It gets even more interesting when you learn what Brinster did with sperm stem cells in 2001. In… read more

Science of Cell Protein Destruction Wins Nobel

October 7, 2004

Discoveries concerning the controlled process of cell protein degradation have earned three scientists the Nobel Prize in Chemistry for 2004.

While work on understanding how proteins are made has received lots of attention, work on understanding how proteins are degraded has been less publicized. But it is now known that when the process goes wrong, it can result in cancer, cystic fibrosis and brain degenerative conditions such as Parkinson’s… read more

Science of smell scoops Nobel Prize

October 5, 2004

Explaining how the human sense of smell works has earned two American scientists the Nobel Prize in Medicine.

Richard Axel of the Howard Hughes Medical Institute at Columbia University and Linda Buck of the Fred Hutchinson Cancer Research Center have helped piece together every step in the process by which cells in the nose capture smelly compounds and transmit signals to the brain, which are perceived as distinct aromas.… read more

Science on verge of new ‘Creation’

March 30, 2004

Scientists now believe it may be possible to create the first artificial unit of life in the next 5 to 10 years and that for the first time, they have just about all the pieces they need to begin making inanimate chemicals come alive.

More than 100 laboratories study processes involved in the creation of life. Spearheading the drive: the European Union’s Programmable Artificial Cell Evolution project, scheduled this… read more

Science Plans “Non-stick” Submarine

October 20, 2003

Nanotechnologists are developing what could be the ultimate non-stick surface. The material is covered with nano-scale needles that enable a liquid, for example, to slip straight off it. One application could be non-stick submarines, which would glide through the water with much less resistance and require less force and fuel.

Science Times 25th Anniversary

November 11, 2003

To celebrate its 25th anniversary, the New York Times Science News section poses 25 of the most provocative questions facing science.

Science to ride gravitational waves

November 10, 2005

Scientists hope to finally detect the most elusive of astrophysical phenomena — gravitational waves — in experiments using ultrasensitive laser interferometers, starting in November.

The aim is to gather data continuously for 18 months. In that time, they would expect to see perhaps two events, maybe more, that can be put down to a passing gravitational wave.

Science-Technology Drive Is Urged to Fight Terror

June 25, 2002

The National Research Council has developed a blueprint for using current technologies and creating new capabilities to reduce the likelihood of terrorist attacks. The recommendations include protecting and controlling nuclear weapons and material, producing sufficient supplies of vaccines and antibodies, securing shipping containers that could hide bombs or toxins, protecting power grids more effectively, improving ventilation systems in public buildings, emergency communications for workers responding to disasters, and more research… read more

Science’s 2007 Breakthroughs of the Year

December 21, 2007

Science recognized “Human Genetic Variation” as the 2007 Breakthrough of the Year, and detailed nine other of the year’s most significant scientific accomplishments in its December 21 issue:

- Cosmic rays’ acceleration may come from passing by the magnetic fields around black holes.
- Researchers determined the structure of the human Beta2-adrenergic receptor.
- Advances in transition metal oxides may herald the next materials revolution for their… read more

Science’s Alternative to an Intelligent Creator: the Multiverse Theory

November 18, 2008

The multiverse may well be the only viable non­religious explanation for what is often called the “fine-tuning problem” (or the anthropic principle)– the baffling observation that the laws of the universe seem custom-tailored to favor the emergence of life.

Stanford physicist Leonard Susskind thinks the various versions of string theory may describe different universes that are all real. He believes the anthropic principle, the multiverse, and string theory are… read more

Science’s Breakthrough Of The Year: Cellular Reprogramming

December 22, 2008

In its annual list of the year’s top ten scientific breakthroughs, the journal Science has given top honors to research that produced “made-to-order” cell lines by reprogramming cells from ill patients.

The cell lines and techniques to produce them offer long-sought tools for understanding — and hopefully someday curing — difficult-to-study diseases such as Parkinson’s disease and type 1 diabetes.

Other scientific achievements named include direct detection of… read more

Science’s breakthrough of the year: The first quantum machine

December 17, 2010

First quantum machine (Aaron D. O'connell and Andrew N. Cleland/University of California, Santa Barbara)

Science magazine has named the discovery of the quantum machine as the most significant scientific advance of 2010.

Physicists Andrew Cleland and John Martinis from the University of California at Santa Barbara and their colleagues designed the machine—a tiny metal paddle of semiconductor, visible to the naked eye—and coaxed it into dancing with a quantum groove.

First, they cooled the paddle until it reached its “ground state,” or… read more

Science’s Elusive Realm: Life’s Little Mysteries

April 27, 2001

The mysterious realm of the mesoscale, a region between molecules and living cells, where proteins fold, charged ions move through cell membranes and messenger molecules read DNA instructions in the cell nucleus, has remained largely inaccessible.

Now work has begun under the auspices of the Institute for Complex Adaptive Matter (ICAM), a new and independent unit of the Los Alamos National Laboratory and the University of California at Berkeley,… read more
