Unbelievable to Get Evidences from Saliva to a ‘Ghost’ Species

27 Jul 17

The history of evolution of salivary protein may direct towards interbreeding between humans and a mysterious ancient relative. Hints have been found by scientists in the saliva hinting that ghost species of archaic humans may have given genetic component to ancestors of people living in sub – Saharan Africa.

The research also suggested that sexual engagement between different archaic human species may not have been unusual. Omer Gokcumen, PhD, an assistant professor of biological sciences in the University at Buffalo College of Arts and Sciences said that it seems that interbreeding between different early hominine species is a norm and not an exception. He said that their research tracked the evolution of a crucial mucin protein called MUC7 which is found in saliva.

When they peeped at the history of gene coding for that particular protein, they saw print of archaic admixture in modern day Sub- Saharan African Populations.

Veteran Tennis Player Leander Paes Plays for His Passion

19 Sep 17

During a recent interview with Leander Paes, he said that he loves the game and is still playing it for his passion.

Leander might have been unseen in India's Davis Cup squad. However, the Indian tennis player is no mood to quit the game until now. Paes said he has nothing to prove to anyone at this stage of his career. Moreover, he also added that his career speaks for itself. The veteran sports person, Paes stated, “at this stage, I play because I love my tennis. I'm very passionate about being an athlete and the lifestyle it incorporates”.

As per the reports, Paes started his career at the age of 16 in 1990 and carries a record for the most Davis Cup doubles wins with 42 victories (equal to Nicola Pietrangeli). He was dropped by new non-playing captain Mahesh Bhupathi for the tie against Uzbekistan earlier this year.

In spite of the ignorance by his one-time partner, the 44-year-old Leander has not lost hope and by his own admission, he is still playing the game for the love of it.

Smart Software That Can Detect People’s Action

19 Sep 17

Scientists have recently developed a computer algorithm that is capable of detecting when drivers are texting or engaged in other distracting activities.

This system work with the help of internally attached cameras and artificial intelligence to identify hand movements that deviate from normal driving behavior and grades or classifies them in terms of possible safety threats.

The developer of this well-researched program, Fakhri Karray, stated that information could be used to improve road safety by warning or alerting drivers when they are dangerously distracted.

The scientists also added that advanced self-driving features are increasingly added to conventional cars which can harm drivers focus. Moreover, these self-driving features are signs of serious driver distraction that can trigger protective measures, said the developer.

This technology has been built while keeping the machine-learning techniques in mind.  The scientists stated that this system can recognize texting, talking on a cell phone or reaching into the backseat to retrieve something.

Wrestling Federation of India: Its Ins and Outs

18 Sep 17

There are clear evidences of wrestling in India since a long period of time; however it has emerged into its latest format after going through various modifications. Earlier it was known as Malla Yudha, Dwand and was played in Akharas. Duryodhna, Bhima, Karna, Jarasandha were counted as great wrestlers in ancient time. Several associations, at the state and national level are managing Wrestling in India.

The national body that is formed to monitor wrestling in India is the Wrestling Federation of India (WFI) that came into existence in 1967 and has been promoting the game in India, since then. There are many wrestling associations are there on state level which is working in collaboration with the WFI for the management of wrestling in India.

Wrestling Federation of India consists of various members including President, Senior Vice President, 8 Vice Presidents, Honorary Secretary General, Treasurer, 6 Joint Secretaries, Two Representative of the Wrestlers, 1 Male and 1 Female as the Member of the Executive Committee.

The prime responsibilities of WFI are: To encourage, promote and control amateur wrestling activities; Give affiliation to Wrestling Associations of States; to conduct systematic coaching camps; to do all such things as may be conducive to the promotion and development of Amateur wrestling etc. It has a Disciplinary Committee to look into any serious issue. 'Rustam-i-Hind' 'Rustam-i-Zamana', and the 'Bharat-Kesri' are some of the titles that are awarded to Wrestling Champion, by WFI.

Latest Mathematical Formula for Driving Quantum Experiments

18 Sep 17

Mathematics is a game of calculation that is always very tricky. Math is used in all aspects of science. Therefore researchers are always trying to discover methods that can be used in simplifying the mathematical problems. For the clinicians who requires to perform high-resolution magnetic resonance applications, like body MRIs for medical diagnosis or spectroscopy for discovering protein structures, a new formula has been developed that will enable them to generate that information themselves.

This formula is to design broadband pulse frequency to excite a population of nuclear spins over a wide band of frequencies that leads to enhanced signal or sensitivity. Traditionally it was done by purely numerical optimization. The challenge that was faced was to design a common magnetic field to excite so many particles. Many scientists had failed to do so. At the same time it is a time taking process.

With the help of the experiment of Washington University body MRIs for medical diagnosis will be very easy and will save time also. The newly designed broadband pulse sequence goes forward to enhance signal or sensitivity in diverse quantum experiments across the magnetic fields from protein spectroscopy to quantum optics. This new method will enhance the quality of result.

The Thrill of Experiencing Bungee Jumping

17 Sep 17

The Bungee Jumping activity remains at the top to be experienced by youth all around the globe. The thrilling activity is experienced when one jumps from a tall structure while being connected to a large elastic cord. Usually a fixed object like building, bridge or crane becomes the tall structure.

Sometimes, it is also possible to jump from a movable object. The movable objects which are able to hover above the ground like hot-air balloon and helicopter functions excellently for bungee jumping. The experience of thrill arises during free-falling and the rebound. Just after the jump of a person, the cord stretches and as the cord recoils, the jumper flies upwards. The jumper continues to oscillate up and down until all the kinetic energy is disappeared.

David Kirke, Geoff Tabin and Simon Keeling, the members of the Oxford University Dangerous Sports Club performed the first modern bungee jumps on 1st April, 1979 from the 250 – feet (76 m). It was done at Clifton Suspension Bridge in Bristol.
