ESO HARPS Instrument Discovers Smallest Ever Extra-Solar Planet

A European team of astronomers [1] has discovered the lightest known planet orbiting a star other than the sun (an “exoplanet”).

The new exoplanet orbits the bright star mu Arae located in the southern constellation of the Altar. It is the second planet discovered around this star and completes a full revolution in 9.5 days.

With a mass of only 14 times the mass of the Earth, the new planet lies at th

A landmark program seeking to bring the promise of genetic research into the “real world” is underway with the first DNA samples to be collected next year. The Guilford Genomic Medicine Iniative is a partnership involving Moses Cone Health System, The University of North Carolina at Greensboro and Duke University.

“This project is an excellent example of solid collaboration in search of a greater good,” Dennis Barry, CEO Emeritus, Moses Cone Health System, says. “After a year of int

Fifteen years ago, the largest telescopes in the world had yet to locate a planet orbiting another star. Today telescopes no larger than those available in department stores are proving capable of spotting previously unknown worlds. A newfound planet detected by a small, 4-inch-diameter telescope demonstrates that we are at the cusp of a new age of planet discovery. Soon, new worlds may be located at an accelerating pace, bringing the detection of the first Earth-sized world one step closer.

Infinitesimal particles of gold have enabled neurobiologists to track down key molecules in the machinery of “entry points” in neurons — offering clues to the organization of a region that has thus far remained largely unknown neuronal territory.

The researchers — from Duke University Medical Center and the University of North Carolina — used electron microscopy to locate molecules tagged with targeted antibodies attached to gold particles — rendering the molecules’ precise

The first 40 million years of Arctic climate history was recovered from beneath the Arctic sea floor on Monday 23 August.

After four days drilling in hazardous conditions the Integrated Ocean Drilling Program’s Arctic Coring Expedition retrieved a 272m core before sea ice forced the work to be abandoned.

The deepest ever Arctic borehole, just 233 kilometres from the North Pole, was interrupted late on Monday when very thick, moving ice floes meant that even the world’s most p

Scientists have determined the precise molecular structure of a potential new target for treating prostate cancer, a disease driven in part by abnormal testosterone activity. The target is part of the androgen receptor, a protein essential for testosterone to function in human cells. Prostate cancer is the most common cancer among men.

The androgen receptor and testosterone – technically, 5-alpha dihydrotestosterone – each drive prostate cancer at different stages of the disease
