1. Scientists using Large Hadron Collider accelerator (LHC) at CERN (European Organisation for Nuclear Research) have discovered a new system of five particles all in a single analysis. The new particles were found to be in excited states (a particle state that has a higher energy than the ground state or absolute minimum configuration) of a particle called Omega-c-zero. Omega-c-zero is a baryon. It is a particle with three quarks, containing two strange and one charm quark. It decays via the strong force into another baryon, called Xi-c-plus (containing a “charm”, a “strange” and an “up” quark) and a kaon K-. Xi-c-plusparticle further decays in turn into a proton p, a kaon K- and a pion p+.Scientists using Large Hadron Collider accelerator (LHC) at CERN (European Organisation for Nuclear Research) have discovered a new system of five particles all in a single analysis. This discovery is unique as observing five new states all at once is very rare. According to the standard convention, these particle states were named Oc(3000)0, Oc(3050)0, Oc(3066)0, Oc(3090)0 b Oc(3119)0. The numbers indicate their masses in megaelectronvolts (MeV), measured by LHCb experiment, one of seven particle physics detector experiments collecting data at LHC, world’s largest and most powerful particle accelerator.
2. Scientists from Eindhoven University of Technology in Netherlands have developed a new wireless Internet network based on infrared rays that is reportedly 100 times faster than existing Wi-Fi (Wireless Fidelity) networks. It has a huge capacity, more than 40 Gigabits per second (Gbit/s). It also does away with the need of sharing Wi-Fi, as every device gets its own ray of light.
3. According to recent report tabled in the Lok Sabha, West Bengal has the highest number of arsenic-affected people in the country. State’s 83 blocks in eight districts have ground water affected by arsenic contamination. So far, state government was able to provide safe drinking water to 52% of the arsenic-affected areas in Bengal. The total number of arsenic-affected people in the country is about 1.48 crore (as of March 2017). West Bengal has topped the list with more than 1.04 crore arsenic-affected persons. Bihar is second with 16.88 lakh persons, with Assam is third with 14.48 lakh victims. According to the WHO’s guidelines the permissible limit of Arsenic in groundwater is 0.01 mg/ litre. In India the permissible limit in drinking water was only recently been revised from 0.05 mg/litre to 0.01 mg/litre. Long-term exposure to arsenic from drinking-water and food can lead to chronic arsenic poisoning. It can cause cancer, skin lesions, developmental effects, cardiovascular disease, neurotoxicity and diabetes.

5. The Father Of Indian Meteorology Dev Raj Sikka, former Director of Indian institute of Tropical Meteorology passed away on 18th March 2017 due to cardiac arrest.

11. First fully India-made train (rake) Medha was flagged off at Dadar station in Mumbai, capital of Maharashtra by Railway Minister Suresh Prabhu via videoconferencing. It has been manufactured by the Integral Coach Factory (ICF) in Chennai, Tamil Nadu. Its rake with 12 coaches has capacity of 6,050 passengers and 1,168 seats. It has in-built systems to minimise breakdowns during the travel. The rake can run at a speed of 110 kmph, It also has LED lighting which reduces energy consumption by approximately 30-35% as compared to the existing rakes. It is also fitted with GPS-based information system to indicate the stations and also has a facility that will help motormen communicate with a guard in case of emergencies.
12. India’s longest surface tunnel in Jammu and Kashmir’s Udhampur district is complete. The 9-km-long tunnel at Chenani passes through the lower Himalayan mountain range on Jammu- Srinagar National Highway. The 9-km-long twin-tube tunnel located at an elevation of 1,200 metres. It is an important part of a 286-km-long four-lane project on the highway. It is India’s first tunnel equipped with world class integrated tunnel control system through which ventilation, signals, fire control, communication and electrical systems are automatically actuated. It reduces travel distance between Jammu and Srinagar by 30 kilometres and save time by three to four hours.
