Bellybutton microbiomes

Ecological research on the human biome to be featured at ESA’s 2011 Annual Meeting in Austin

Public awareness about the role and interaction of microbes is essential for promoting human and environmental health, say scientists presenting research at the Ecological Society of America's (ESA) 96th Annual Meeting from August 7-12, 2011. Researchers shed light on the healthy microbes of the human body and other research on microbial and disease ecology to be presented at ESA's 2011 meeting in Austin, Texas.

Bellybutton microbiomes

Human skin is teeming with microbes—communities of bacteria, many of which are harmless, live alongside the more infamous microbes sometimes found on the skin. Nina Rountree from North Carolina State University and colleagues set out to dispel the myth that all bacteria on the skin are disease-causing germs. The researchers cultured the bacterial communities living within bellybuttons of 391 individuals from across the U.S. and published photos of the cultures anonymously in the online Bellybutton Bacteria Culture database. They chose bellybuttons as an area of the body that is generally protected from excretions, soaps and ultraviolet ray exposure.

The experiment generated interest among citizen scientists and provided clues about the stability of bacterial communities over time, the significant turnover between participants' bacterial communities and similarities of bacterial communities between family members. The Bellybutton Bacteria Culture database received 55,000 visitors in only three months.

The research entitled "Beta-diversity of human skin bacteria studied with the citizen science approach" led by Nina Rountree from North Carolina State University, will be presented Friday, August 12 during the "Biodiversity" poster session.

The Ecological Society of America is the world's largest professional organization of ecologists, representing 10,000 scientists in the United States and around the globe. Since its founding in 1915, ESA has promoted the responsible application of ecological principles to the solution of environmental problems through ESA reports, journals, research, and expert testimony to Congress. ESA publishes four print journals—and one online-only, open-access journal Ecosphere—and convenes an annual scientific conference. Visit the ESA website at or find experts in ecological science at

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
