Three planets were discovered,

two orbiting stars similar to the

Sun and one orbiting a more

massive and evolved red giant

star. The first two planets both

have about one third the mass of

Jupiter and orbit their host stars in

seven and five days respectively.

The third planet takes 122 days to

orbit its host and is more massive

than Jupiter .

The first of these planets proved

to be orbiting a remarkable star --

it is one of the most similar solar

twins identified so far and is

almost identical to the Sun [5]. It is

the first solar twin in a cluster that

has been found to have a planet.

Two of the three planets are "hot

Jupiters" -- planets comparable to

Jupiter in size, but much closer to

their parent stars and hence much

hotter. All three are closer to their

host stars than the habitable zone

where liquid water could exist.

"These new results show that

planets in open star clusters are

about as common as they are

around isolated stars -- but they

are not easy to detect," adds Luca

Pasquini (ESO, Garching,

Germany), co-author of the new

paper [6]. "The new results are in

contrast to earlier work that failed

to find cluster planets, but agrees

with some other more recent

observations. We are continuing

to observe this cluster to find how

stars with and without planets

differ in mass and chemical

makeup."

Some Facts And Myths Regarding Diabetes

Diabetes

The Nobel Prize in Physics 2013

PETER W.HIGGS FRANCOIS ENGLERT

The Nobel Prize in Physics 2013 was awarded jointly to François Englert and Peter W. Higgs "for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed

through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN's Large Hadron Collider"

true. Being overweight or obese

raises the risk of becoming diabetic, they are risk factors, but

do not mean that an obese person will definitely become diabetic.

Many people with type 2 diabetes were never overweight. The

majority of overweight people do not develop type 2 diabetes.

Diabetes is a nuisance, but not serious - two thirds of diabetes

patients die prematurely from stroke or heart disease. The life

expectancy of a person with diabetes is from five to ten years

shorter than other people's. Diabetes is a serious disease.

Children can outgrow diabetes - this is not true. Nearly all children

with diabetes have type 1; insulin-

producing beta cells in the

pancreas have been destroyed. These never come back. Children

with type 1 diabetes will need to take insulin for the rest of their

lives, unless a cure is found one day.

Many presumed "facts" are thrown

about in the paper press, magazines and on the internet regarding diabetes;

some of them are, in fact, myths. It is important that people with diabetes,

pre-diabetes, their loved ones, employers and schools have an

accurate picture of the disease. Below are some diabetes myths:

People with diabetes should not exercise - NOT TRUE!! Exercise

is important for people with diabetes, as it is for everybody

else. Exercise helps manage body weight, improves cardiovascular

health, improves mood, helps blood sugar control, and relieves

stress. Patients should discuss exercise with their doctor first.

Fat people always develop type 2 diabetes eventually - this is not

However, they must keep an eye on the size of

the portions. Whole grain starchy foods are better, as is the case for people without

diabetes.

One person can transmit diabetes to another

person - NOT TRUE. Just like a broken leg is not infectious or contagious. A parent may pass

on, through their genes to their offspring, a higher susceptibility to developing the disease.

If you have diabetes you cannot eat chocolates or sweets - people with diabetes can eat

chocolates and sweets if they combine them with exercise or eat them as part of a healthy

meal.

.Children can outgrow diabetes - this is not true.

Nearly all children with diabetes have type 1; insulin-producing beta cells in the pancreas

have been destroyed. These never come back. Children with type 1 diabetes will need to take

insulin for the rest of their lives, unless a cure is found one day.

Don't eat too much sugar, you will become diabetic - this is not true. A person with

diabetes type 1 developed the disease because their immune system destroyed the insulin-

producing beta cells. A diet high in calories, which can make people overweight/obese,

raises the risk of developing type 2 diabetes, especially if there is a history of this disease in

the family. Diabetics cannot eat bread, potatoes or pasta -

people with diabetes can eat starchy foods.

along, as spiritual approaches maintain?" ask

Hameroff and Penrose in the current review.

"This opens a potential Pandora's Box, but

our theory accommodates both these views,

suggesting consciousness derives from

quantum vibrations in microtubules, protein

polymers inside brain neurons, which both

govern neuronal and synaptic function, and

connect brain processes to self-organizing

processes in the fine scale, 'proto-conscious'

quantum structure of reality."

After 20 years of skeptical criticism, "the

evidence now clearly supports Orch OR,"

continue Hameroff and Penrose. "Our new

paper updates the evidence, clarifies Orch

OR quantum bits, or "qubits," as helical

pathways in microtubule lattices, rebuts

critics, and reviews 20 testable predictions of

Orch OR published in 1998 -- of these, six

are confirmed and none refuted."

An important new facet of the theory is

The recent discovery of warm temperature

quantum vibrations in microtubules inside

brain neurons by the research group led by

Anirban Bandyopadhyay, PhD, at the

National Institute of Material Sciences in

Tsukuba, Japan (and now at MIT),

corroborates the pair's theory and suggests

that EEG rhythms also derive from deeper

level microtubule vibrations. In addition, work

from the laboratory of Roderick G. Eckenhoff,

MD, at the University of Pennsylvania,

suggests that anesthesia, which selectively

erases consciousness while sparing non-

conscious brain activities, acts via

microtubules in brain neurons.

"The origin of consciousness reflects our

place in the universe, the nature of our

existence. Did consciousness evolve from

complex computations among brain neurons,

as most scientists assert? Or has

consciousness, in some sense, been here all

introduced. Microtubule quantum vibrations

(e.g. in megahertz) appear to interfere and

produce much slower EEG "beat

frequencies." Despite a century of clinical

use, the underlying origins of EEG rhythms

have remained a mystery. Clinical trials of

brief brain stimulation aimed at microtubule

resonances with megahertz mechanical

vibrations using transcranial ultrasound have

shown reported improvements in mood, and

may prove useful against Alzheimer's

disease and brain injury in the future.

Manoj Rawat PGT Physics)

Discovery of quantum vibrations in 'microtubules' corroborates theory

of consciousness

A review and update of a controversial 20-year-old theory of consciousness published in Physics of Life Reviews claims that

consciousness derives from deeper level, finer scale activities inside brain neurons. The recent discovery of quantum vibrations

in "microtubules" inside brain neurons corroborates this theory, according to review authors Stuart Hameroff and Sir Roger

Penrose. They suggest that EEG rhythms (brain waves) also derive from deeper level microtubule vibrations, and that from a

practical standpoint, treating brain microtubule vibrations could benefit a host of mental, neurological, and cognitive condi tions.

The theory, called "orchestrated objective reduction" ('Orch OR'), was first put forward in the mid-1990s by eminent

mathematical physicist Sir Roger Penrose, FRS, Mathematical Institute and Wadham College, University of Oxford, and prominent

anesthesiologist Stuart Hameroff, MD, Anesthesiology, Psychology and Center for Consciousness Studies, The University of

Arizona, Tucson. They suggested that quantum vibrational computations in microtubules were "orchestrated" ("Orch") by synaptic

inputs and memory stored in microtubules, and terminated by Penrose "objective reduction" ('OR'), hence "Orch OR."

Microtubules are major components of the cell structural skeleton.Orch OR was harshly criticized from its inception, as the brain

was considered too "warm, wet, and noisy" for seemingly delicate quantum processes.. However, evidence has now shown warm

quantum coherence in plant photosynthesis, bird brain navigation, our sense of smell, and brain microtubules.

NANOTECHNOLOGY: what is it and how it is? Nanotechnology is the understanding and control of matter at the nanoscale, at dimensions

between approximately 1 and 100 nanometers, where unique phenomena enable novel applications.

Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging,

measuring, modeling, and manipulating matter at this length scale.

Matter such as gases, liquids, and solids can exhibit unusual physical, chemical, and biological

properties at the nanoscale, differing in important ways from the properties of bulk materials and single

atoms or molecules. Some nanostructured materials are stronger or have different magnetic properties

compared to other forms or sizes or the same material. Others are better at conducting heat or electricity.

They may become more chemically reactive or reflect light better or change color as their size or structure

is altered.

A nanometer is one-billionth of a meter. Find out just how tiny that actually is.

Special high-powered microscopes have been developed to allow scientists to see and manipulate

nanoscale materials. Learn about those microscopes here.

Learn how scientists can carefully create, control, move, and change materials at the nanoscale.

Benefits and Applications

After more than 20 years of basic nanoscience research and more than a decade of focused R&D

under the NNI, applications of nanotechnology are delivering in both expected and unexpected ways on

nanotechnology’s promise to benefit society.

Nanotechnology is helping to considerably improve, even revolutionize, many technology and

industry sectors: information technology, energy, environmental science, medicine, homeland security, food

safety, and transportation, among many others. Described below is a sampling of the rapidly growing list of

benefits and applications of nanotechnology.

Fibre optics technology

This article discusses the history of fiber optics, from the optical semaphore telegraph to the

invention of the first clad glass fiber invented by Abraham Van Heel, applications and

different uncharacteristic of Fiber Optics. Today more than 80 percent of the world’s long-distance voice

and data traffic is carried over optical-fiber cables.

Fiber-Optic Applications—Telecommunications applications of fiber-optic cable are widespread, ranging

from global networks to desktop computers.

Fiber-optic cables are constructed of three types of materials: glass, plastic, and plastic-clad silica (PCS).

Propagation Modes—There are two main modes of fiber-optic propagation: multimode and single mode.

Previous Page Next Page

These two modes perform differently with respect to both attenuation and chromatic dispersion.

Fiber-Optic Characteristics—Fiber-optic system characteristics include linear and nonlinear characteristics.

Linear characteristics include attenuation and interference. Nonlinear characteristics include single-phase

modulation (SPM), cross-phase modulation (XPM), four-wave mixing (FWM), stimulated Raman scattering

(SRS), and stimulated Brillouin scattering (SBS).

Fiber Types— it has various multimode and single-mode fiber types currently used for premise,

metro, aerial, submarine, and long-haul applications.

Fiber-Optic Cable Termination—Removable and reusable optical termination in the form of metal

and plastic connectors plays a vital role in an optical system

Short Message Service (SMS) :today’s fashion

Short Message Service (SMS) is a text messaging service component of phone, web, or mobile communication systems, using standardized communications that allow the exchange of short text messages between fixed

line or mobile phone devices.SMS text messaging is the most widely used data application in the world, with 3.6 billion

active users, or 78% of all mobile phone subscribers. The term "SMS" is used as an acronym for all types of short text

messaging, as well as the user activity itself, in many parts of the world. SMS is also being used as a form of direct

marketing known as SMS marketing.

The first SMS message was sent over the Vodafone GSM network in the United Kingdom on 3 December 1992, from

Neil Papworth of Sema Group (now Mavenir Systems) using a personal computer to Richard Jarvis of Vodafone using

an Orbitel 901 handset. The text of the message was "Merry Christmas."

The first commercial deployment of a short message service center (SMSC) was by Aldiscon part of Logica (now part

of Acision) with Telia (now TeliaSonera) in Sweden in 1993, followed by Fleet Call (now Nextel) in the US, Telenor in

Norway and BT Cellnet (now O2 UK) later in 1993. All first installations of SMS gateways were for network notifications

sent to mobile phones, usually to inform of voice mail messages. The first commercially sold SMS service was offered

to consumers, as a person-to-person text messaging service by Radiolinja (now part of Elisa) in Finland in 1993. Most

early GSM mobile phone handsets did not support the ability to send SMS text messages, and Nokia was the only

handset manufacturer whose total GSM phone line in 1993 supported user-sending of SMS text messages.

Initial growth was slow, with customers in 1995 sending on average only 0.4 messages per GSM customer per

month. One factor in the slow takeup of SMS was that operators were slow to set up charging systems, especially for

prepaid subscribers, and eliminate billing fraud which was possible by changing SMSC settings on individual handsets

to use the SMSCs of other operators. In 2010, 6.1 trillion SMS text messages were sent. This translates into 193000

SMS per second. SMS has become a massive commercial industry, earning $114.6 billion globally in 2010. The global

average price for an SMS message is $0.11, while mobile networks charge each other interconnect fees of at least

$0.04 when connecting between different phone networks.

from Andy Bechtolsheim in 1999. On

June 7, 1999, a $25 million round of

funding was announced, with major

investors including the venture capital

firms Kleiner Perkins Caufield & Byers

and Sequoia Capital. This funding has

triggered the growth of the Google

Corporation. The following year, the

creators of Google created advertising

system, which advertised various search

keywords. This system is one of the

major reasons behind the success of

Google.

During the following years Google

bought many famous companies and

extended its partnership. In 2004,

Google acquired Keyhole, Inc. The

result of this partnership was Earth

Viewer that gave a 3-D view of the

Earth. Google renamed the service to

Google Earth in 2005. Two years later,

Google bought YouTube for $1.65

billion. In 2007 Google purchased Grand

Central for $50 million. In addition

Google has many partners all around

the world. It’s hard to believe but

Google is even a partner of NASA.

Google was created in 1996 by two

Stanford university students – Larry

Page and Sergey Brin. They created it as

a research project for their PhD degree.

These two bright students came up with

an idea to create a universal search

engine that would compare internet

sites by the relationships between them

and other sites on the World Wide Web.

Page and Brin originally nicknamed their

new search engine "BackRub", because

the system checked backlinks to

est imate the importance of a

site. Eventually, they change the name

to Google, which was from the

misspelling of the name googol, which

means the number 1 followed by 100

zeros. Google originally started running

a t t h e u n i v e r s i t y ’ s d o m a i n

google.stanford.edu.

The company was incorporated in 1998

September 4 (at a friend’s garage by the

way).Google was incorporated in 1998

… at a garage.

At the early stages of Google

corporation, it has received various

funding starting with 100.000 $ funding

Today Google is as famous as

the internet. Google holds the

monopoly of internet search

engines and offers various

services starting with online

translators ending with Google

Maps. Recent development of

the company shows that Google

Corporation has a bright future

ahead.
