Computational method for pinpointing genetic factors that cause disease

Posted: 05 Sep 2012 12:43 PM PDT

Researchers have developed a computational method of identifying "causal" genetic variants that lead to particular diseases, with wide application for genome-wide association studies.

LEDs winning light race to save energy, the environment

Posted: 05 Sep 2012 11:19 AM PDT

Light-emitting diode light bulbs, also known as LEDs, are more environmentally friendly than compact fluorescent and incandescent lights, new research shows. LEDs' environmental edge is expected to grow substantially as technology and manufacturing methods improve by 2017.

Seeing the birth of the universe in an atom of hydrogen: Radio waves used to uncover oldest galaxies yet

Posted: 05 Sep 2012 11:19 AM PDT

Astronomers are using radio telescopes to find radio waves emitted by hydrogen atoms, which were abundant in the early days of the universe. This new field of research, called "21-centimeter cosmology," opens the way to learning more about the universe's oldest galaxies.

First holistic view of how human genome actually works: ENCODE study produces massive data set

Posted: 05 Sep 2012 11:09 AM PDT

The Human Genome Project produced an almost complete order of the 3 billion pairs of chemical letters in the DNA that embodies the human genetic code -- but little about the way this blueprint works. Now, after a multi-year concerted effort by more than 440 researchers in 32 labs around the world, a more dynamic picture gives the first holistic view of how the human genome actually does its job.

Tough gel stretches to 21 times its length, recoils, and heals itself: Biocompatible material much tougher than cartilage

Posted: 05 Sep 2012 10:49 AM PDT

A team of experts in mechanics, materials science, and tissue engineering has created an extremely stretchy and tough gel that may pave the way to replacing damaged cartilage in human joints. Called a hydrogel, because its main ingredient is water, the new material is a hybrid of two weak gels that combine to create something much stronger. Not only can this new gel stretch to 21 times its original length, but it is also exceptionally tough, self-healing, and biocompatible -- a valuable collection of attributes that opens up new opportunities in medicine and tissue engineering.

Quantum teleportation goes the distance: Record-breaking distance of 143 kilometers through free space

Posted: 05 Sep 2012 10:43 AM PDT

An international research team has achieved quantum teleportation over a record-breaking distance of 143 kilometers through free space.

Champagne proves a fantastic playground for physicists

Posted: 05 Sep 2012 09:28 AM PDT

The fleeting life of champagne bubbles intrigues scientists; collapsing bubbles are common in our everyday lives but are still not fully understood. Two reviews explore collapsing bubbles and bubble flow patterns in champagne glasses. These phenomena are of much wider interest because of the huge importance of bubbles in many natural and industrial processes.

Explosion of galaxy formation lit up early universe

Posted: 05 Sep 2012 08:12 AM PDT

The universe was dark until the first stars began to form, but really lit up once massive hydrogen clouds began birthing galaxies of stars. A study by researchers using data from the South Pole Telescope finds that this period, the Epoch of Reionization, was later and more explosive than thought, ending 13 billion years ago. The clues come from minute temperature fluctuations in the cosmic microwave background radiation.

Robotic exoskeletal device: Preliminary research findings for Ekso in spinal cord injury

Posted: 05 Sep 2012 08:11 AM PDT

Preliminary research findings have been released from a clinical study of the wearable robotic exoskeletal device, Ekso (Ekso Bionics). Initial results are promising for the potential application of Ekso-assisted walking in rehabilitation, in exercise/wellness programs, in the community and for home use.

Galileo didn't invent thermometer that bears his name

Posted: 05 Sep 2012 08:11 AM PDT

The great Italian scientist Galileo may have been the first person to use a telescope to observe the heavens, helping spark the scientific revolution of the 16th century, but Galileo definitely did not invent the famous thermometer and captivating curiosity that bears his name, according to a new article.

Powerful new explosive could replace today's state-of-the-art military explosive

Posted: 05 Sep 2012 08:10 AM PDT

Borrowing a technology used to improve the effectiveness of drugs, scientists are reporting discovery of a new explosive more powerful than the current state-of-the-art explosive used by the military, and just as safe for personnel to handle.

Wireless window sentinel draws its power from its environment

Posted: 05 Sep 2012 08:09 AM PDT

Window contacts tell users if a window is open or closed. Typically, such sensors are wire-based. Scientists working with industry partners recently developed a new system that operates without wires or batteries. It draws its power from its environment: from sunlight and ambient heat.

Globular star cluster with a secret

Posted: 05 Sep 2012 05:39 AM PDT

A new image from the European Southern Observatory's La Silla Observatory in Chile shows the spectacular globular star cluster Messier 4. This ball of tens of thousands of ancient stars is one of the closest and most studied of the globular clusters and recent work has revealed that one of its stars has strange and unexpected properties, apparently possessing the secret of eternal youth.

Astronomers discover 'pigtail' molecular cloud

Posted: 05 Sep 2012 05:37 AM PDT

A research team has discovered a molecular cloud with a peculiar helical structure by observation with the NRO 45m Telescope at the National Astronomical Observatory of Japan. The team named it a "pigtail" molecular cloud from its morphology. The "pigtail" molecular cloud is located in the galactic center, approximately 30,000 light years away from the solar system.
