David Rennie went through tough time for two years as he had to go through regular dialysis because of kidney problems he had. The 54-year-old Shelton resident was provided a means of survival by dialysis, but he was not able to perform certain daily tasks because of the condition.

Diabetes and high blood pressure worsened his condition to such an extent that he required a kidney transplant. He was all set for a surgery in December as his wife, Margaret, agreed to donate a kidney to him, but it later surfaced that his wife was not a good match for him.

They were in despair until they came to know about a historic eight-patient kidney transplant that took place March 3 at Yale-New Haven Hospital.

A new report released on Thursday shows that if legal age to buy cigarette is increased to 21 years then it can help in reducing smoking rate and would also save hundreds of thousands of lives by the end of the century.

Majority of the US states allow people to buy cigarettes at age 18. However, there are four states, Alabama, Alaska, New Jersey and Utah that allow tobacco to be sold only to those who are 19 years old and above.

The Campaign for Tobacco-Free Kids said that 58 localities in seven states do not allow the sale of cigarettes to people under-21 years of age. As per the law passed in 2009, the Food and Drug Administration has the authority to regulate tobacco.

The U.S. space agency NASA has revealed that it has recently captured images of a strong flare erupting from the surface of the sun.

The agency said that the X-class solar flare from the sun’s surface was the strongest category of sun storm noticed in 2015.

As per experts, solar flares are intense emissions of radiations spewed from the sun’s surface. These flares have the capability to disrupt the global positioning, radio, and satellite signals, but cannot penetrate earth’s atmosphere.

As per the details released by NASA, the rare image of the solar flares were captured on March 11, 2015, and peaked at 16:22 GMT.

The discovery of about 1,000 new fish species since 2008 has been reported by a census of the world’s marine species. Researchers put in efforts to review all databases to gather one definitive list of existing information of sea life known as World Register of Marine Species (WoRMS).

WoRMS co-chair Jan Mees, Chair of the European Marine Board and Director of the Flanders Marine Institute (VLIZ) in Belgium, said that WoRMS wants to make a master list of all organisms that have ever been noticed and described in the world oceans.

Mees also said that the work is almost completed and all the historical data have been entered in the database. Experts have identified the redundant names. Eight years have been utilized by researchers in order to combine the existing databases.

The latest results from China's first lunar rover have suggested that the moon's past was more active complex than previously thought.

China's Yutu moon rover has found a proof of at least nine different rock layers deep under its wheels, which indicated that the area was surprisingly geologically active over the past 3.3 billion years.

Long Xiao, lead author of the new study, a researcher at the China University of Geosciences in Wuhan, said they have found two interesting factors about Moon.

Researchers have developed an electrically conductive film that can aid devices having the ability to use sunlight and split water into hydrogen fuel.

Study’s co-author Nathan Lewis of the California Institute of Technology (Caltech) said, “We have developed a new type of protective coating that enables a key process in the solar-driven production of fuels to be performed with record efficiency, stability and effectiveness”.

The system also ensures safety and does not lead to the production of hazardous mixtures of hydrogen and oxygen. The researchers affirmed that the development is a significant one and could lead to the efficient artificial photosynthetic systems, which are also known as solar-fuel generators or artificial leaves.
