Future Health Technology

Probably you’ve head a lot about biotechnology. What is it? In short, bio technology is the technology based on biology. For instance biotechnology harnesses cellular and biomolecular processes to develop technologies and products that help improve people lives and the health or using the biological researches to make useful food products, such as bread and cheese, and to preserve dairy products.

Also progress in biotechnology is currently working on environmentally-friendly biodegradation processes for a cleaner, healthier planet, experimenting with until-now untapped energy sources, and devising useful consumer chemicals such as adhesives, detergents, dyes, flavors, perfumes, and plastics.

The predicted capabilities of biotechnology include
End of world hunger, global starvation
Foods that are better for you and last longer
Disease and pest resistant crops
Accurate delivery of precise amounts of drugs, e.g., targeting cancer cells without damaging nearby healthy cells
Regenerative medicine, replacement organs
Designer organisms
Slowing or stopping aging
Biological computing, wearable computers
Biological fabrication of clothing, plastics, and building materials
Environmentally friendly manufacturing processes that minimize waste
Microbial cleansers
Ultra-strength, lightweight materials

Mars Landing – Watch Online

NASA TV will broadcast the landing live from the Jet Propulsion Laboratory’s mission control room in Pasadena, California, along with expert commentary – and you can watch it below.

NASA’s MARS SCIENCE LABORATORY, also known as the Curiosity rover, is about to touch down on the Red Planet.

Launched on 26 November 2011, the one-tonne, nuclear-powered, US$2.5 billion explorer will spend years exploring the planet’s surface, searching for clues that Mars might have once have had – or could still have – conditions suitable for primitive, microbial life.

God Particle

You have probably head about Higgs boson. Scientists working at the world’s largest atom smasher say they have enough evidence of the long-sought-after Higgs boson. What is wxactly Higgs boson and how does it work?

There is a gist of the standard model, developed in the early 1970s: The Higgs boson appeared 13.7 billion years ago in the chaos of the Big Bang and turned the flying debris into galaxies, stars and planets. Our entire universe is made of 12 different matter particles and four forces. Among those 12 particles, you’ll encounter six quarks and six leptons. Quarks make up protons and neutrons, while members of the lepton family include the electron and the electron neutrino, its neutrally charged counterpart. Scientists think that leptons and quarks are indivisible; that you can’t break them apart into smaller particles. Along with all those particles, the standard model also acknowledges four forces: gravity, electromagnetic, strong and weak. Here is the picture found online trying to get illustrated explanation of the subject.

As theories go, the standard model has been very effective, aside from its failure to fit in gravity. Armed with it, physicists have predicted the existence of certain particles years before they were verified empirically. Unfortunately, the model still has another missing piece – the Higgs boson.

“We think the Higgs boson is a manifestation of the fact that the universe is filled with a force that we haven’t been able to detect yet that gives other particles mass,” Lykken told NPR. “It exists for a billionth of a billionth of a billionth of a second, or something like that, and then falls apart into other particles.”

Thus, scientists are in a bit of a quagmire, according to the AP. While they appear to have enough evidence to report the existence of the “God particle,” they still hedge on whether to report “a discovery.” It’s a fine line, indeed, but one that scientists will likely continue to debate.
