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?

Clue to Mysterious Biological Clock Cycle

Humans as well as living organisms have a circadian life rhythm, generated from an internal clock. Researchers have found tiny molecules known as miRNAs are central constituents of the circadian clock. This discovery holds an array of applications for the future such as the sleep deprivation and disorders related to daily life cycle.

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.
