Black Hole Induced Galaxy Existence?

A new scenario has emerged from observations of a black hole without a home, may indicate that black holes may be building their own host galaxy. This may be the long-sought missing link to understanding why the masses of black hole are larger in galaxies that contain more stars. The study suggests that super-massive black holes can trigger the formation of stars
The chicken and egg analogy hence: did a galaxy or black hole come first?

Diminishing a Hurricane

Microsoft is steering funds to Intellectual Ventures, a private company that buys and licenses patents and inventions. The next task on the list is killing hurricanes. The idea is using large amounts of cool water from massive floating bowls, deployed by airplane. The temperature must drop at least 4.5 F in order to diminish a hurricane force.

Arming Immune System against H1N1

Viruses multiply at an incredible pace once it infects the victim, but researchers have developed a screening platform named LEAPS (Ligand Epitope Antigen Presentation System) that identifies epitopes, small parts of virus that elect specific immune reactions. It is guided to immature dendritic cells, immune system's conductors that fight against invaders. The LEAPS technology directs an immune response in a desired direction.

New Wound Dressing helps Infections from Burns

Statistically, 70% of all people die from infections after severe burns, but a new wound dressing developed at Tel Aviv University could cut that value dramatically. The dressing has fibres that is loaded with drugs like antibiotics to speed up the healing process and dissolve when complete, while eradicating infection causing bacteria. The technology is complex, even though the concept is simple. The wound dressing must maintain a certain level of moisture while acting as a shield and it must allow fluids to leave the wound at a specific rate.

32-bit One Instruction Computer

An abstract machine that uses only one instruction, without the need for a machine language opcode is called one instruction set computer. The advantage with RISC is simplifying the CPU core by reducing the complexity of the instruction set allows faster speeds, more registers, and pipelining to provide the appearance of single-cycle execution. There are several ways to construct a single instruction CPU.

Medical Imaging Improvement with Nanoparticles

Researchers from National Institute of Standards and Technology have discovered a method of using nano-particles to illuminate the cellular interior to reveal its slow processes. The quantum dot nano-particle glows when exposed to light. When coated with organic materials, scientists can manipulate the particle to attract to specific proteins to be examined. The research team focused primarily on characterizing quantum dot properties to target protein inside blood cells to study. However, there are concerns about toxicity and other properties of the nano-particles.

Microsoft experimenting a tool called Pivot that brings a new method of interacting with the Web on the PC. It combines the ideas of web-browsing, web search, image organizing and text information into a graphical interface to help users sift through data. Pivot's potential lies in the ability to see the whole data soup, stir it to see details within or zoom right in to see some of the individual ingredients.

Flying Spy Bots

The US military wants to shoot off loads of flying, spying robots using missiles to make for faster sureillance and aerial attack. The first time for military: unmanned, long-range, ultra-high speed surveillance. The military refrained from building global strike missles due to similiarity of an atomic attacker which may trigger another world war. Drones coming from missles may give a larger geographic range for surveillance, while analyzing their own video. However, analysts are not equipped to cope with loads of data and parse them in real time.

Research Inspired by Wings

Insect wings have evolved into incredible nanoscopic material structures. Some wings are superhydrophobic, meaning they cannot become wet and the tiniest droplet of water is instantly repelled. Researchers are now using insect wings as a model for making self-cleaning. frictionless and superhydrophobic materials. If successful, development of self-cleaning, water-resistant and friction-free coatings for a range of machine components, construction materials and other applications, including nano- and micro- electromechanical systems. The team has carried out atomic force microscopy analysis of the surface of insect wings in order to determine the forces with which fine dust particles stick, or rather don't stick to the wing. The work confirms that only very small forces are needed to shed nanoscopic dust particles, two to twenty nano-Newtons.

Penguin DNA Challenges Accuracy of Genetic Dating Techniques

Frozen DNA samples from penguins that died 44,000 years ago in Antarctica challenges the accuracy of traditional genetic aging measurements that underestimate the age of many specimens by several folds. Therefore, a biological specimen determined by traditional DNA testing can be two to six times older. DNA testing may be fundamentally flawed as a result of this discovery. The molecular clock rate is the key in determining the accuracy of genetic analysis.

Humaniod Robot's Task of Door Opening

It is still a challenge for Roboticsts to design humanoid robots to run, open doors and etc. Arisumi, researcher at Japan's National Institute of Advanced Industrial Science and Technology (AIST) and one of the top centers for humanoid research, explains that opening doors for humanoid robots is a challenge. A large force is needed initially to open a door, especially for old western style doors that spring back. A motion to open the door requires a desired angle and precise support for the entire open action in one-follow through movement. Many other facts need to be considered such as upper body position, foot position, opening angle of the door, angular velocity of the door, impact velocity of the robot and etc. The research team developed a technique and computation for HRP-2 humanoid robot to open the door.

Optomechanical Crystal Confines Light and Sound

Physicists and engineers at the California Institute of Technology have developed a nano-scale crystal that traps both light and sound. The interaction of light quanta and sound quanta are strong enough to produce significant mechanical vibrations. Frequencies as high as gigahertz can give devices the ability to send large amounts of information.

Harnessing Energy from Natural Motions

Scientists have been havesting electricity from the motions of everyday life for years, but efficiencies and methods to capturing energy is limited. The success of these devices is limited because they can only perform well under a narrow band of frequenies. The strategy is to develop a device that can convert a range of vibrations by using magnets to 'tune' the banwidth of the experimental device. The potential of the new approach surpasses conventional linear devices.

Nanofibre Solar Power

Researchers found a new way to make solar power more cheaper and flexible to use. The nano-scale wires built around optical fibres allow more surface area for light to interact with, which improves cell efficiency. Using this technology, photovoltaic generators are foldable, concealable and mobile. Traditionally, silicon based solar cells are most efficient because it absorbs the most light. The new method starts with commerical optical fibre without outer layer and wraps zinc oxide nanowires around the fibre. In addition, light only needs to enter at the ends of the fibre, making it space efficient.

The State of Hydrogen Research

Hydrogen fuel cell research is in the midst of a raging debate. There are great challenges to the electric-vehicle infrastructure and most people will overlook the challenges. Many people do not have access to plug-in garages and it would take billions to upgrade the smart grid to coupe with the demand. On the other hand, the cost of mass-producing fuel cells is going down. The biggest issue with electric vehicles is the fact that people lose interest in things that do not produce results quickly.
