Scientists Discovered a Gigantic Exoplanet, HATS-18b

                On 2 June 2016, International team of astronomers found an alien world named HATS-18b. It is a giant hot Jupiter exoplanet tidally spinning up its parent star. The team led by Kaloyan Penev of Princeton University carried out the observation campaign between April 2011 and July 2013.

About Exoplanet, HATS-18b:

•          The newly discovered planetary system could be a great laboratory for to test the theories of planet-star interactions.
•          The research team used the Hungarian-made Automated Telescope Network-South (HATSouth) to obtain over 1000 images of this sun-like star while finding the exoplanets orbiting HATS-18

Scientists Identified a Process to Remove DNA Molecules from X-Files

                On 6 June 2016, Scientists of the University of Sheffield identified the process of removal of DNA molecules from the iconic double-helical structure. Scientists were trying to unlock the mystery for over 20 years. The research has unlocked a crucial part of the mystery as to how the human DNA can replicate and repair itself. It is essential for all life forms. Jon Sayers, the Professor of Functional Genomics at the University of Sheffield is the lead author of the study.

NASA Successfully Deploys Bigelow Expandable Activity Module

                On 28 May 2016, The National Aeronautics and Space Administration (NASA) and Bigelow Aerospace successfully deployed the Bigelow Expandable Activity Module (BEAM) on the International Space Station. It is the first experimental inflatable room attached to the space station.

Highlights:

•          It is an expandable habitat technology demonstration for the International Space Station.
•          Expandable habitats greatly decrease the amount of transport volume for future space missions.
•          These expendables are light-weight and require minimal payload volume on a rocket, but expand after being deployed in space to potentially provide a comfortable area for astronauts to live and work.
•          They also provide a varying degree of protection from solar ad cosmic radiation, space debris, atomic oxygen, ultraviolet radiation and other elements of the space environment.

New Elements on Periodic Table get Names

                Time to rewrite the science textbooks: The periodic table has new names for four elements. The International Union of Pure and Applied Chemistry, the gatekeeper to the periodic table, announced on 8 June the proposed names for elements 113, 115, 117 and 118: nihonium, moscovium, tennessine and oganesson. The new names for the four super-heavy radioactive elements will replace the seventh row’s placeholders of ununtarium, ununpentium, ununseptium and ununoctium.

                IUPAC officially recognized the elements in December and gave naming rights to teams of scientists from the US, Russia and Japan, who made the discoveries. The proposed names had to follow IUPAC rules and are available for public review. People have until November to object to the proposals. Nihonium, symbol Nh, was discovered by scientists at the Riken Institute in Japan. They are the first from Asia to earn the right to propose and addition to the table. The name comes from “Nihon,” which is one of the two Japanese words for Japan.

                A trio of research Institutions – the Joint Institute for Nuclear Research, in Russia; Oak Ridge National Laboratory, in Tennessee; and Lawrence Livermore National Laboratory, in California – were given the right to propose names for elements 115 and 117. Moscovium, symbol Mc, is named for Moscow, which is near the Joint Institute for Nuclear Research.

                Tennessine, symbol Ts, gets its name from the state of Tennessee, where Oak Ridge National Laboratory is. After californium, it is second element named for one of the 50 states. Naming rights for element 118 went to the same Russian researchers and the Americans from the Lawrence Livermore National Laboratory. They selected Oganeson, symbol Og, for Yuri Oganessian, who helped discover several super-heavy elements.

New Device Could Predict Asthma Attacks

                Asthma patients may soon do away with their inhalers as researchers have developed an integrated, wearable system that monitors a user’s environment, heart rate and other physical attributes with the goal of predicting and preventing asthma attacks. They have tested the system in the lab and on a limited number of human subjects for proof of concept demonstration, and have confirmed that all of the sensors work, and that the system accurately compiles the data.

Scientists Propose to Build First Synthetic Human Genome

                A group of 25 scientists on 2 June proposed an ambitious project to create a synthetic human genome, or genetic blueprint, in an endeavour that is bound to raise concerns over the extent to which human life can or should be engineered. A synthetic human genome potentially could make it possible to create humans who lack biological planets raising the spectre, for instance, of made to order human beings with special genetic enhancements. The scientists said that was not their aim. They said potential applications from a synthetic human genome include: growing transplantable human organs; engineering immunity to viruses; engineering cancer resistance and accelerating vaccine and drug development using human cells and organs.

                The project aims to build such a synthetic genome and test it in cells in the laboratory within 10 years. The project, which arose after meeting of scientists in May at Harvard University, was unveiled in the journal Science. They acknowledged that their undertaking is controversial and said they would seek public involvement and the consideration of ethical, legal and social implications. They said they hoped to get $100 million in public and private funding to launch it this year and expect total costs of less than the $3 billion used for the original Human Genome Project that completely mapped human DNA for the first time in 2003. A synthetic genome would involve using chemicals to create the DNA present in human chromosomes.

A Bionic Leaf That Turns Sunlight Into Liquid Fuel

                Scientists have developed a bionic leaf that uses solar energy to split water molecules and hydrogen-eating bacteria to produce liquid fuels, that surpasses the efficiency of photosynthesis seen in fastest growing plants. Before, people were using artificial photosynthesis for water-splitting, but this is a true A-to-Z system, and we’ve gone well over the efficiency of photosynthesis in nature. While the study shows the system can be used to generate usable fuels, its potential does not end there.

                Dubbed “bionic leaf 2.0,” the new system builds on previous work by researchers – though was capable of using solar energy to make isopropanol – faced a number of challenges. Chief among those challenges was the fact that the catalyst used to produce hydrogen – a nickel molybdenum zinc alloy – also created reactive oxygen species, molecules that attacked and destroyed the bacteria’s DNA.

                To avoid that problem, researchers were forced to run the system at abnormally high voltages, resulting in reduced efficiency. They designed a new cobalt-phosphorus alloy catalyst, which they showed does not make reactive oxygen species. That allowed them to lower the voltage, and that led to a dramatic increase in efficiency. The system can now convert solar energy to biomass with 10% efficiency, far above the one percent seen in the fastest growing plants. In addition, researchers were able to expand the portfolio of the system to include isobutanol and isopentanol.
