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

Herbs-for-Muscles-Pain.jpg (400×265)
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."

New Apps Analyzation For Malicious Behavior Have Discovered

 In July 2013 the Russian software company "Doctor Web" discovered malicious apps in the app store "Google Play".Doctor Web, comes with its own terms and conditions, informed Google, the apps were still available for download for several days.Doctor Web estimates that in this way approximately 25,000 smartphones were used in order to cheat and make money illegally.

Computer scientists have made software which helps to discover malicious apps in the app store, from the German Saarland University.This software notice where the app gains sensitive data and where data is going from the smartphones and if software finds any link between source and sink then it gives information about suspect behavior or reports about that.

"Your address book is read, hundreds of instructions later and without your permission an SMS is sent or a website is visited", said Erik Derr.

The computer scientists from Saarbrucken use new technique to recognize a link between source and sink and give suspicious combinations as input.
Erik Derr said, "So far we have tested up to 3000 apps with it. The software analyzes them fast enough that the approach can also be used in practice."

4 To 6 Years Old Nursery Kids Can Solve Algebra


140306130048-hero.jpg (323×182)

Solving algebraic equations is not so much easy for every student, but most nursery kids and kindergarteners can solve algebraic questions before becoming a part of maths class.

Recently published study in the journal Developmental Science, reseachers find that most nursery students and kindergarteners, children between four and six, can solve basic algebra and study lead by author and post-doctoral fellow Melissa Kibbe and Lisa Feigenson, associate professor of psychological and brain sciences at Johns Hopkins University's Krieger School of Arts and Sciences.

Post-doctoral fellow Melissa Kibbe said, "these are very young children, some of whom are just learning to count, and few of whom have even gone to school yet, are solving basic algebra with little effort." "They do it by using their "Approximate Number System" their inborn sense of quantity and number."

The "Approximate Number System" is also known as "number sense" and helps humans and animals to size up the quantity of objects.

In the study, children sat one by one with an examiner who told them about the two characters, each of whom had a cup filled with an unknown quantity of items.They saw the pile before it was added to, and after, so they had to decide how many objects Gator's cup and Cheetah's cup kept.


At the end, the examiner mixed up the cups, and asked the children select whose cup it was.Mostly the children knew whose cup it was.Director of Johns Hopkins Laboratory for Child Development, Feigenson said , "What was in the cup was the x and y variable, and children nailed it." "Gator's cup was the x variable and Cheetah's cup had y variable. We found that young children are very good at this. It appears that they are harnessing their gut level number sense to solve this task."

Algebra is difficult for teenagers because "One possibility is that formal algebra relies on memorized rules and symbols that seem to trip many people up," Feigenson said.The ANS helps in solving basic algebra and are needed to master the complex algebra problems that are taught later in the school age years.The study find that an ANS ability does not follow gender boys versus girls, both have equal proportions in solving algebra.Feigenson said, "we see no evidence for gender differences in our work on basic number sense."

Feigenson said, "We find links at all ages between the precision of people's Approximate Number System and their formal math ability." "But this does not necessarily mean that children with poorer precision grow up to be bad at math. For example,children with poorer number sense may need to rely on other strategies, besides their gut sense of number, to solve math problems. But this is an area where much future research is needed."

"Tribo-Electric" Which Converts Movement Into Power,Human Movement as well



Researchers had built a prototype device which changes movement into power, at the Georgia Institute of Technology.Scientists in the United States said Tuesday it lies within reach, thanks to a smart way to harvest energy called tribo-electricity.

A professor of materials science and engineering, Zhong Lin Wang described the invention a "breakthrough." He told AFP by email, "Our technology can be used for large-scale energy harvesting, so that the energy we have wasted for centuries will be useful."

"Tribo-electric" is a modern device with previous rules from the Greek word for "rub."The device generates electricity from friction between two things that cause a charge of electrons travel from one to the other like walking on nylon carpet with plastic-soled shoes.The device has ability to generates 1.5 watts.



In a new study published in the journal Nature Communications, Wang's team said they had overcome key hurdles to converting a haphazardly-generated electrical charge into current.

There are two circular sheets, an electron "donor" and the other an electron "receiver" moved together by rotary movement.An electrical charge isolate would use if the sheets are separated.It has one more disc with electrodes, work as a bridges the gap and allows the current to flow at a top speed of 3,000 revolutions per minute.

Wang said, "It can run on a gentle wind or tap water, or "random jerky motions," including human movement, to provide the rotation.""As long as there is mechanical action, there is power that can be generated."

Wang also said, "the prototype used copper for the rotator and gold for the electrodes in lab tests, but these could easily be substituted for low-cost synthetics."

The team of researchers is still working to harvest power from the ocean.


By 3D Printer Teen Develops Robohand for Boy(Video)


Mason Wilde is interested in 3-D printers and made a hand for a 9-year-old family friend. Matthew was born with only a thumb on his right hand, but a 3-D printer solves this problem.

Mason Wilde, a 16-year-old Louisburg High School junior, loaded blueprints from "Robohand" onto computers and using their 3-D printer at Johnson County Public Library made a prosthetic hand that is driven by the motion of the wrist.The hand opens if the wrist move up and the fingers close if move down.Mason Wilde wants eight hours to build this Robohand with the 3-D printer.

Jennifer said, “Every day, kids were asking him, ‘What happened to your hand, what happened to your hand,’ and I noticed it was wrecking his spirit,”. “Social stigma was starting to creep in on him.”

Matthew's mother discovered a Robohand on the internet but it is so expensive approximately $18,000, his mother cannot afford this hand.Mason Wilde made ​​some changes to the hand developing the structures of the mechanism.

"When it is all done, to be able to say you gave a kid a hand, gave a kid the ability to grasp something and let him high five or hand shake, it is a pretty amazing feeling," Mason Wilde said.

"I actually have fingers. I didn't know what that felt like until now," Matthew said.

Matthew said, “I call it my toy tool, It is the future.”

"It has been a huge blessing. It has changed the conversation from, 'what happened to your hand?' to, 'oh my gosh! That is so cool.' That is huge when you are 9 and when you're a little bit different," Matthew's mom said.

Mason Wilde is looking into a career in the biomedical field and has inspired to start a non-profit to make prosthetics from 3-D printers for other children.
