Airship concept, hybrid between drone and satellite

A new project of an autonomous airship has introduced which work as a drone and a satellite as well.This prototype airship is known as "StratoBus", has been developed in Europe.This project is organized by Thales Alenia Space ,Airbus Defence & Space, Zodiac Marine and CEA-Liten, and airship is able to perform a several actions such as border monitoring and maritime surveillance, telecommunications, broadcasting and navigation.

According to the company notes, "We design, integrate, test and operate high-performance satellite technologies in both civil and defense sectors."

The StratoBus is 70 to 100 meters long and 20 to 30 meters in diameter with the shell fabric is made of carbon fiber.The StratoBus will be able to support payloads up to 200 kg and work at an altitude of about 20 kilometers in the lower levels of the stratosphere but above air traffic and jet streams. 

"This prototype airship has Potential to perform different tasks like monitoring, boosting GSM network capacity for public events and GPS augmentation over dense traffic areas", company said.

One of the main purpose of this airship is carries "technological innovations" and will be able to capture the sun's rays.The airship will be equipped with solar panels and a light reversible fuel cell for energy storage.The first prototype is planned to be introduced within the next five years.

Sea Snake Survives Without Water To Drink, Research

Researchers have discovered the yellow-bellied sea snake can live out in the ocean because it can survive extreme dehydration, according to study published in Proceedings of the Royal Society B: Biological Sciences.

“These snakes refuse to drink salt water, even when dehydrated, they need fresh water to survive,” Lillywhite said.

To see this how sea snake survive without fresh water, researchers captured 500 yellow-bellied sea snakes on the Guanacaste coast off of Costa Rica and tested them in lab to found how they live without fresh water.

The yellow-bellied sea snake does not drink sea water because it is not able to filter out all the salt like sea turtles.In order to survive the sea snake is totally dependent on fresh water from rainfall.The researchers noticed that several specimens lost up to 18 percent weight when there is no fresh water for drink.

The researchers also found that snakes have glands that make it possible for snakes to remove salt from the foods they eat and also allow to drink saltwater.Snakes skin also help prevent salt from being absorbed.

Lillywhite said, "if global climate change causes drought conditions to worsen, sea snakes and other marine vertebrates that depend on rainfall for fresh water could be hurt.“
Lillywhite also said that understanding the water requirements and drinking behaviors of marine vertebrates could help with conservation efforts. In areas of intensifying drought, they will need to move or die out.”

Ocean Cleanup Project to Remove Wastes From Sea Surface

 A 19 year old aerospace engineering student at the Delft University of Technology, Boyan Slat has introduced a plan to clean the oceanic wastes from the surface of sea, this project is known the Ocean Cleanup Array.

Boyan Slat said, "it is a project to clean one-third of the total ocean surface plastic pollution or about 7,250,000,000 kilogrammes."This project could reduce the death rate of aquatic animals and also help out to reduce oceanic pollutants like PCB and DDT.

He posted in his website.“Plastic pollution costs governments, companies and individuals millions of dollars in damages per year, due to loss in tourism, vessel damages and (inefficient) beach clean-ups.”

Ocean Cleanup Array would have platform with booms to collect plastic waste due to the gyre current and by the flow of water wastes come to the platform then the trasher will recycle it.He said booms is better than nets because it covers a wider area and will save auqutic animals from catch.



The platforms would be stationary, will be self-supporting because of harnessing solar energy or currents.“According to current estimations – due to the plan’s unprecedented efficiency – recycling benefits would significantly outweigh the costs of executing the project,” Slat describes.The concept has the ability to remove 7,250,000,000 kg of world’s oceans plastic in just five years.This forcast is based on Ocean Surface Current Simulator (OSCURS) data.

This project is still under construction.If we want succee in this project we need to rise the importance of recycling, and reducing our consumption of plastic packaging,” said Slat.

Orange Light Makes People To Be More Alert, Research

In Belgium a team of researchers has discovered that people exposed to blue light show less brain activity and the other hand those exposed to orange light show more brain activity.

The study published in Proceedings of the National Academy of Sciences, researchers explain study, how they shined different colour lights in eyes of volunteers going for fMRI scanning and orange light might have an effect on the circadian rhythm.

The researchers was working on melanopsin and have believed that the melanopsin has an impact on the circadian rhythm.For more detail, the orange, blue or different lights were shined in volunteers eye's for ten minutes then their brains were scanned.

The researchers found during the brain scans studying, when the volunteers were exposed to orange light greater the brain activity, when exposed to green light a very small increase were noticed and blue light did not show any activity.The researchers said, orange light make melanopsin more active than other lights and messaging the brain to when it's time to be more alert.

The study did not show that orange light has an effect on the circadian rhythm and makes more alert.If it possible or turn out to be true in future then it might be a helpful for people to remain more alert where need to be.

Ancient Masks Go On Exhibition In Jerusalem

The oldest mildstone masks have discovered and have displayed at the Israel Museum in Jerusalem.These stone masks have been discovered in near the Jerusalem's Judean desert and hills.

The 9,000-year-old limestone masks think to be the world's oldest mildstone masks.They have been made to look like the spirits of dead ancestors and it is possible that they were used in religious or traditionals ceremonies.The masks have round gaps displays of noses, eyes and teeth.

The 9,000 year old masks have found near Jerusalem and offer a rare glimpse of some of civilisation's first communal rituals.They were found in the range of about 20-mile in Jerusalem where the Judean hills meet the Judean desert.Each mask stone weights about one or two kg.

James Snyder, said all of the masks were discovered near Jerusalem."It's quite exciting," said James Snyder, director of the Israel Museum, which is hosting the seven-month exhibit."When you go back to objects that are this old, that are so much before the theology that becomes Judaism, Christianity and then Islam, to feel that there is a kind of a connection, that this is all part of a continuous story, is something that is pretty thrilling."

"The masks dated back to the creators of civilisation",Debby Hershman said, the exhibition's curator.Hershman also said that the people who created the masks were the creators of civilization and were first farmers."

It took 10 years of carbon-14 testing for experts to decide origin of the collection, the Associated Press news agency reports.

The Face to Face exhibition opens for public from March 11 to September 13 at the Israel Museum in Jerusalem.

London Announces New Technique For Pedestrian Safety

London has introduced the new technology for pedestrian to cross the raod more safely.The new pedestrian crossing sensors to help make it easier and safer for people to cross the road throughout the capital.

The Mayor of London "Boris Johnson" said the system has ability to adjust times of traffic signals automatically, traffic lights help the system to measure situations how many pedestrians are standing on the side of raod and need some more time.

The new technology "Pedestrian Split Cycle Offset Optimization Technique" or "pedestrian SCOOT", uses state-of-the-art camera technology to notice circumstances like how many pedestrians are waiting to cross the raods.If the cameras detect the number of pedestrians are waiting , they inform the signals that pedestrians want more "green light" time with the signaling system.

"The system would be bringing huge benefits to those waiting to cross the road where there is heavy pedestrian demand," managing director of surface transport at TfL, Leon Daniels said.

TfL made its Safe Streets for London in July, according to report on a road safety action plan for London 2020 and the main purpose of the report is to discrease the rate of people killed and badly injured on London's streets.

Increase, Decrease in Pain By Light, Researchers

Scientists are working on the nature of pain, by the help of light researchers get pain relief and get more pain as well.The mice in Scott Delp's lab are making it possible for scientists study about pain and about more like without any injury why pain feel.

The researchers used a technique called optogenetics, which involves light sensitive proteins to put into the nerves called opsins.One light color causes the mice to feel more pain and other causes the reduction in pain. Delp's colleague Karl Deisseroth, MD, PhD, a co-author of the study was developed Optogenetics and the study published on Feb. 16 in Nature Biotechnology.

The researchers said that the new research allows to better understand different kinds of pain and gives a chance researchers to discover more in future on the nature of pain, touch and other feelings.

"The fact that we can give a mouse an injection and two weeks later shine a light on its paw to change the way it senses pain is very powerful," Shrivats Iyer said.

Scott Delp, who takes an interest in muscles and movement , whose lab made this discovery,was using optogenetics to control movement, pain, touch and other sensations suddenly he found that the opsins were also making the nerves to control pain."We thought, wow, we're getting pain neurons—that could be really important," Scott Delp said.

At the end, Scott Delp said, "Developing a new therapy from the ground up would be incredibly rewarding," he said. "Most people don't get to do that in their careers."
