Keepers had been incubating the egg for five weeks, following a month long incubation by the chick’s father, carefully monitoring it for signs of pipping: the process in which the chick starts to break through the shell. The chick remained in an isolet for four days and is now in a specially designed brooding box.
The box will be not be on exhibit, but will be accessible on Friday, March 14, by webcam on the Zoo’s Web site at http://nationalzoo.si.edu/Animals/Birds/Kiwi/default.cfm.
Since kiwis are nocturnal, the best time to view the chick exploring and foraging in its box will be in the evening.
The sex of the chick is still unknown and is difficult to determine by sight. For this reason, Bird House staff enlisted the help of National Zoo geneticists. Using DNA samples swabbed from the inside of the egg and from the bird’s beak, the geneticists hope to decipher its sex in the coming weeks.
This is only the third time in the Zoo’s history that a kiwi has successfully hatched. The first hatching occurred in 1975 and was the first to occur outside of New Zealand. The National Zoo did not have another successful hatching until 2005; that male bird, Manaia, may currently be seen Mondays, Wednesdays and Fridays at the 11 a.m. “Meet a Kiwi” program at the National Zoo’s Bird House. Kiwis in captivity are extremely rare—only four zoos outside of New Zealand have successfully bred kiwis, and only three U.S. zoos, including the National Zoo, exhibit them.
There are five species of kiwi and all are unique to New Zealand. The North Island brown species of kiwi is the national bird of New Zealand. They are widely thought to be the most ancient bird and have existed in New Zealand for more than 30 million years. Kiwis typically mate for life, and both parents share the responsibility of caring for the egg. After kiwi chicks hatch, however, they receive no parental care. Unlike other bird species, kiwis hatch fully feathered and equipped with all of the necessary skills they need to survive.
The North Island brown kiwi species is classified as endangered by the International Union of Conservation of Nature. The wild population is declining at a rate of approximately 5.8 percent a year. Nearly 60 percent of all wild North Island brown kiwi chicks are killed by stoats, a species of weasel and an introduced predator. The remaining wild population of the North Island brown kiwi is estimated at roughly 24,000, down from 60,000 in the 1980s.

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.
Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.
Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.
Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.
After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.
"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
