Digital Holographic Microscopy hunts down microbes in Enceladus

Tinuku ~ The researchers designed holographic imagery to detect signs of life in outer space. An attempt to explore samples and identify microbes as signs of life on the moon Enceladus, a team of researchers at the California Institute of Technology offers a technique called Digital Holographic Microscopy using lasers to record 3-D images to find space microbes.

Tinuku Digital Holographic Microscopy hunts down microbes in Enceladus

The Saturn orbiting Enceladus Moon has a lot of ocean-sized water hidden beneath the ice shell that lines the entire surface, but scientists on Earth at a distance of about 790 million miles have difficulty identifying the marked life potential of microbial existence.

"You have more difficulty identifying microbes than a speck of dust, you have to distinguish between Brownian motion as a random motion of matter and the movement of deliberate living organisms," said Jay Nadeau of the California Institute of Technology in Pasadena, California.

Enceladus is the sixth moon of Saturn and 100,000 times smaller than Earth. A world allows objects on the surface to have a speed of 239 meters per second. A very large geyser wreaks 250 kilograms of water vapor every second through cracks in the moon ice shell and regularly spills to a height of nearly 500 kilometers above the surface.

Nadeau said the water mixture into space gave a rare opportunity in which a probe on Enceladus' surface collected samples that might contain microbes. But the continued problem is finding microbes in water samples is a difficult job.

"Bacteria are lacking a lot of cellular features. Bacteria are usually in the form of lumps and smaller in diameter than a hair, sometimes not different from dead material granules. Looking at patterns and chemistry seems useful, but you do not know the material is alive and not because of movement," Nadeau said.

Nadeau and the team suggest the movement of many living organisms potentially used for extraterrestrial life. Movements of living organisms can also be triggered or enhanced by "feeding" the microbial electrons and observing active development. They send research results to Astrobiology.

Digital Holographic Microscopy is built for astrobiology using lasers and light that bounces off objects and is measured when returned to the detector. These scattered lights contain information about amplitude and phase, while the computer reconstructs 3-dimensional object imagery to show movement.

Nadeau and colleagues used water samples from the Arctic rarely inhabited bacteria to identify organisms with a population density of just 1,000 cells per milliliter or similar to those in some of Earth's most extreme environments such as subglacial lakes.

European Union and ASEAN to restart Free Trade Agreement

Tinuku - European Union (EU) and ASEAN have agreed to restart the process of forming Free Trade Agreement (FTA). Singapore Prime Minister Lee Hsien Loong as ASEAN coordinator for EU-ASEAN relations said on Saturday to build a framework to identify potential sectors to finalize the deal.

Lee also said the EU and ASEAN had agreed to restart the process of establishing a free trade agreement between the two blocs. The EU and ASEAN launched talks towards a pact in 2007 but ignored the process two years later as the EU voted to negotiate bilaterally with each country.


"As coordinators, we look forward to forming a framework to identify where areas where we have the potential to make a deal," Lee said.

"Working on a deal may take longer than the end of the year. But if we can identify where the big opportunities are, our trade-offs, then I hope we will have better success," Lee said.

"One of the things we expect is that European nations are able to manage their soci…

Rolls-Royce plans for flying taxi service

Tinuku - Rolls-Royce Holdings plc has designed a propulsion system for flying taxi and is starting search for partners to help develop a project it hopes could take to the skies as soon as early next decade. British jet engine maker said on Sunday it had drawn up plans for an electric vertical take-off and landing (EVTOL) vehicle which could carry to five people at speeds of up 250 mph for approximately 500 miles.

The company joins a variety of companies racing to develop flying taxis, which could revolutionize the way people travel. Aviation and technology leaders are working to make electric-powered flying taxis a reality, including Airbus, U.S. ride- sharing firm Uber and a range of start-ups including one backed by Google co-founder Larry Page, called Kitty Hawk.


Rolls-Royce’s design will be showcased in digital form at the Farnborough Airshow, which starts on Monday. The company is looking for an airframer and a partner to provide aspects of the electrical system to help commerci…

Britain announced its first launch site for the space market

Tinuku - UK on Monday ran an important leap for the construction of the first vertical launch space launch site. The proposed space port at Sutherland in the north of Scotland has been awarded US$3.3 million in funding by the government-owned UK Space Agency to develop a ground-breaking launch site.

Government Business Secretary Greg Clark Monday launched the start of a Great British Space Age that will see vertically-launched space rockets and satellites take off from the new spaceport. UK Space Agency said it selected the Sutherland site because Scotland is the best place in Britain to reach highly sought-after satellite orbits with vertically launched rockets.


The initial funding will go to Scotland's Highlands and Islands Enterprise agency to develop the Sutherland site which will use a combination of proven and innovative rocket technologies to pave the way for a world-leading spaceflight market.

The UK Space Agency is also making available a new 2.65 million U.S. dollar fund…
