आरोग्य और विज्ञान समाचार

आरोग्य और  विज्ञान समाचार 


(१) अंगूर एक उपयोगी पादप यौगिक  Resveratrol से भरपूर है। यह 


रसायन हमारी मानसिक प्रतिक्रियाओं को तीव्रतर बनाता है। 

Resveratrol is a member of a group of plant compounds called polyphenols. These compounds are thought to 

have antioxidant properties, protecting the body against the kind of damage linked to increased risk for 

conditions 

such as cancer and heart disease. Resveratrol is found in the skin of red grapes, but other sources include 



peanuts and berries.


(२)सुखाये हुए अंजीर (Dried figs )फिनोल्स ,ओमेगा -३ और ओमेगा 


-६ लिए रहते हैं। ये तत्व हमें परिहृदय रोगों (Coronary artery 


disease ) से बचाये रहने में सहायक सिद्ध हुए हैं।


साइंसदानों की माने तो अंतरिक्ष में ऐसे अबूझ कण तैर रहें हैं जो हिग्स 


बोसोन (गॉड पार्टिकिल )से भी सूक्ष्मतर हैं जिनसे मिलकर ही हिग्स 


कणों  की निर्मिति हुई है। 



निराकार ,निर्गुण ,निर्विशेष ब्रह्म का एक गुण है :वह एक साथ सब जगह मौज़ूद होता है। निर्गुण  का मतलब

गुणहीना नहीं है बल्कि यह है वह चरम चक्षुओं से दिखलाई नहीं देता है दिव्यचक्षु चाहिए उसे देखने के लिए।

हालाकि वह स्वयं सब कुछ देखता है सब कारणों का कारण है लेकिन उसका स्वयं का कोई कारण नहीं है।

विज्ञानियों ने उसे गॉड पार्टिकिल नाम दे दिया। हिग्स कण कह दिया। अब कहा जा रहा है इस कण में भी इस

से सूक्ष्म संरचनाएं निहित हैं।जिनके संयोग से परस्पर आकर्षण से यह अस्तित्व में आता है। यानी द्रव्य के

बुनियादी कण हिग्स पार्टिकिल से भी छोटे हैं।

अब तक हिग्स बोसोन को ही बुनियादी माना जाता  था। अब तक यही समझा जाता था जड़ और जंगम

मनुष्य और वनस्पति कुछ बुनियादी कणों की ही निर्मिति हैं। अलबत्ता इनका नियंता एक फ़ोर्स पार्टिकल

(बलीय -कण )समझा जाता था।




यही इन्हें परसपर प्रतिक्रिया करके द्रव्यमान मुहैया करवाता था। और स्वयम सम्पूर्ण  अंतरिक्ष में  व्याप्ति

के बाद भी अदृश्य अगोचर बना रहता था।यानी एक अदृश्य बल क्षेत्र की निर्मिति है हिग्स बोसोन। जहां कुछ

भी न था वहाँ भी य़ह था ऐसा समझा जाता था। कुल मिलाकर किस्सा यह रहा है द्रव्य के कथित बुनियादी

कणों (बलीय  कणों )में भी आगे संरचनाएं मौज़ूद हैं। जिनका निरंतर अन्वेषण ज़ारी है।

पहले क्वार्क के संयोजन से न्यूट्रॉन ,प्रोटोन जैसे कणों  की अवधारणा ने पालथी मारी और अब हिग्स बोसोन

जो अब तक खुद बिचौलिए की भूमिका में था खुद अन्वेषण के दायरे में आ गया है पढ़िए इसी विषय पर मूल

आलेख इस सूचना के साथ कि बुनियादी कण उसे कहा जाएगा जिससे ज्यादा बुनियादी और कुछ भी नहीं हो

यानी जिसमें आगे संरचनाएं नहीं हों  :

Scientists announce possibility of particle 


smaller than Higgs Boson

Until 2012, nobody was certain it existed till the European Organisation for Nuclear Research 

(CERN) announced they had found the God Particle. 



Scientists now say that it is more likely than ever now that there must be particles smaller than 

Higgs particle 

"Nobody has seen them yet; particles that are smaller than the Higgs particle. However theories predict their existence, and now the most important of these theories have been critically tested," they said. 

The result: The existence of the yet unseen particles is now more likely than ever". 

The Higgs Boson is central part of the Standard Model of particle physics that describes how the 

world is constructed.

According to the Standard Model, everything, from flowers and people to stars and planets, consists of just a few building blocks: matter particles. These particles are governed by forces mediated by force particles that make sure everything works as it should. 

The entire Standard Model also rests on the existence of a special kind of particle: the Higgs particle. This particle originates from an invisible field that fills up all space. Even when the universe seems empty this field is there. Without it, we would not exist, because it is from contact with the field that particles acquire mass. 

On 4 July 2012, at the CERN laboratory for particle physics, the theory was confirmed by the discovery of a Higgs particle. 

CERN's particle collider, LHC (Large Hadron Collider), is probably the largest and the most complex machine ever constructed by humans. 

Last year, the Royal Swedish Academy of Sciences announced that the 2013 Nobel Prize for 

Physics to Peter Higgs after whom the particle is named. 

But in a new twist, Thomas Ryttov, particle physicist and associate professor at the Centre for Cosmology and Particle Physics Phenomenology refers to the theories, that over the last five years have been put forward for the existence of particles in the universe that are smaller than the Higgs particle. 

Having given these theories a critical review, he finds no new signs of weakness in them: 

"There seems to be no new or unseen weaknesses. My review just leaves them just stronger," he 

says. 

Over the past 5-8 years, a handful of theories have drawn particular interest from particle physicists. They all predict that there must be one or more types of particles that are even smaller than the Higgs particle. So far it has however not been possible to prove their existence. 

"Here we are interested in the pursuit of such as yet unknown particles. We know that there must be a force that binds them together so that they together can create something bigger than themselves, something composite; a Higgs particle. It must happen similarly to quarks binding together to form protons and neutrons. If we can understand this force, we can explain and predict new physical phenomena like new particles," explains Ryttov. 

This force is called the strong force, he says. It cannot be compared to gravity, which also has the ability to keep two objects close together. The effect of gravity depends on the fact that the two objects are not too far from each other, and the closer they are to each other the stronger the force of gravity will be. The strong force has the opposite effect: It is weak when two particles are close to each other, but strong - extremely strong - if you try to pull them apart.

Thomas Ryttov and his colleagues believe that the so-called techni-quarks can be the yet unseen particles, smaller than the Higgs particle. If techni-quarks exist they will form a natural exention of the Standard Model which includes three generations of quarks and leptons. These particles together with the fundamental forces form the basis of the observed matter in the universe.


Particles smaller than the Higgs boson exist? 

There are unknown particles floating around the universe that may be even smaller than the Higgs boson, the 'God 

particle' discovered in 2012, scientists say. 

The so-called techni-quarks can be the yet unseen particles, smaller than the Higgs particle that will form a natural 

extension of the Standard Model which includes three generations of quarks and leptons. 

These particles together with the fundamental forces form the basis of the observed matter in the universe. 

"Nobody has seen them yet; particles that are smaller than the Higgs particle. However theories predict their existence, 

and now the most important of these theories  have been critically tested. The result: The existence of the yet unseen 

particles is now more likely than ever," researchers said. 

"I gave them a very critical review," said Thomas Ryttov, particle physicist from the University of Southern Denmark. 

Ryttov referred to the theories that have been put forward over the last five years for the existence of particles in the 

universe that are smaller than the Higgs particle. 

"There seems to be no new or unseen weaknesses. My review just leaves them just stronger," he said.
