Figuring out flow dynamics Posted: 31 Jul 2013 01:47 PM PDT Scientists have been building models of turbulent flow. Recently, they developed a new and improved way of looking at the composition of turbulence near walls, the type of flow that dominates our everyday life. Their research could lead to significant fuel savings, as a large amount of energy is consumed by ships and planes, for example, to counteract turbulence-induced drag.

Spitzer Discovers Young Stars with a 'Hula Hoop' Posted: 31 Jul 2013 12:57 PM PDT Astronomers using NASA's Spitzer Space Telescope have spotted a young stellar system that "blinks" every 93 days. Called YLW 16A, the system likely consists of three developing stars, two of which are surrounded by a disk of material left over from the star-formation process.

NASA's Cassini sees forces controlling Enceladus jets Posted: 31 Jul 2013 12:53 PM PDT The intensity of the jets of water ice and organic particles that shoot out from Saturn's moon Enceladus depends on the moon's proximity to the ringed planet, according to data obtained by NASA's Cassini spacecraft.

Nanomaterials: Sized-up for strength Posted: 31 Jul 2013 12:20 PM PDT Experiments and numerical simulations show that miniaturized ultra-small platinum cylinders weaken when their constituents are reduced in number.

Universal law for light absorption in 2-D semiconductors Posted: 31 Jul 2013 10:32 AM PDT Researchers have demonstrated a universal law of light absorption for 2-D semiconductors. This discovery not only provides new insight into the optical properties of 2-D semiconductors and quantum wells, it should also open doors to exotic new optoelectronic and photonic technologies.

Game changer for synthesizing new materials: Method synthesizes thousands of new compounds with ultra low thermal conductivity Posted: 31 Jul 2013 10:32 AM PDT A chemist likens his lab's newly published accomplishments to combining two flavors of ice cream and churning out thousands of flavors to appeal to any taste bud. In reality, he is referring to his method of synthesizing thousands of new compounds with ultra low thermal conductivity.

Using gold and light to study molecules in water Posted: 31 Jul 2013 09:29 AM PDT Thanks to a new device that is the size of a human hair, it is now possible to detect molecules in a liquid solution and observe their interactions. This is of major interest for the scientific community, as there is currently no reliable way of examining both the behavior and the chemical structure of molecules in a liquid in real time.

Robots strike fear in the hearts of fish: Anxious zebrafish help researchers understand how alcohol affects fear Posted: 31 Jul 2013 09:29 AM PDT The latest in a series of experiments testing the ability of robots to influence live animals shows that bio-inspired robots can not only elicit fear in zebrafish, but that this reaction can be modulated by alcohol. These findings may pave the way for new methodologies for understanding anxiety and other emotions, as well as substances that modulate them.

Physicists discover theoretical possibility of large, hollow magnetic cage molecules Posted: 31 Jul 2013 09:29 AM PDT Researchers have discovered, in theory, the possibility of creating large, hollow magnetic cage molecules that could one day be used in medicine as a drug delivery system to non-invasively treat tumors, and in other emerging technologies.

Researchers successfully spoof an $80 million yacht at sea Posted: 31 Jul 2013 09:28 AM PDT A radio navigation research team discovered they could subtly coerce a 65-meter superyacht off its course, using a custom-made GPS device. The purpose of the experiment was to measure the difficulty of carrying out a spoofing attack at sea and to determine how easily sensors in the ship's command room could identify the threat.

Guided growth of nanowires leads to self-integrated circuits Posted: 31 Jul 2013 09:28 AM PDT Teaching nanowires self-control from the outset enabled scientists to produce complex electronic nanocomponents.

Tiny, brightly shining silicon crystals could be safe for deep-tissue imaging Posted: 31 Jul 2013 09:26 AM PDT Tiny silicon crystals caused no health problems in monkeys three months after large doses were injected, marking a step forward in the quest to bring such materials into clinics as biomedical imaging agents, according to a new study.

Surprising result discovered when looking into effects of carbon nanotubes and soil sorption of toxicants Posted: 31 Jul 2013 09:25 AM PDT When it comes to carbon nanotubes (CNTs) in the soil, recent research shows that the new materials do not affect the sorption of the toxic part of oil called polycyclic aromatic hydrocarbons (PAHs).

Key factors for wireless power transfer Posted: 31 Jul 2013 09:25 AM PDT What happens to a resonant wireless power transfer system in complex electromagnetic environments? Researchers explored the influences at play in this type of situation and describe how efficient wireless power transfer can be achieved in the presence of metal plates.

Saturn's Mimas and Pandora: Two moons passing in the night Posted: 31 Jul 2013 08:30 AM PDT The Saturn moons Mimas and Pandora remind us of how different they are when they appear together, as in this image taken by NASA's Cassini spacecraft. Pandora's small size means that it lacks sufficient gravity to pull itself into a round shape like its larger sibling, Mimas. Researchers believe that the elongated shape of Pandora (50 miles, or 81 kilometers across) may hold clues to how it and other moons near Saturn's rings formed.

Computational biology: Cells reprogrammed on the computer Posted: 31 Jul 2013 07:55 AM PDT Scientists have developed a model that makes predictions from which differentiated cells -- for instance skin cells -- can be very efficiently changed into completely different cell types -- such as nerve cells, for example. This can be done entirely without stem cells. These computer-based instructions for reprogramming cells are of huge significance for regenerative medicine.

Chemists develop innovative nano-sensors for multiple proteins Posted: 31 Jul 2013 06:35 AM PDT Chemists have developed a new method for parallel protein analysis that is, in principle, capable of identifying hundreds or even thousands of different proteins. It could be used to detect the presence of viruses and identify their type in tiny samples. At the same time, it is very cost-effective and quick.
