WINNER OF A GLOBAL COMPETITION: MEET DXTER, THE REAL-LIFE STAR TREK TRICORDERScience
WINNER OF A GLOBAL COMPETITION: MEET DXTER, THE REAL-LIFE STAR TREK TRICORDERScience
fiction has given inventors a lot of inspiration, for instance, who wouldn’t like to have the sonic screwdriver of Dr. Who or the Tricorder from Star Trek? Well, while there hasn’t been any news on the sonic screwdriver, there is news about the all-purpose medical device known as the Tricorder.
The medical world would be changed forever with the Tricorder as it would be able to diagnose a patient instantly. The X-Price Foundation wanted the Tricorder so badly that they started a worldwide competition to find out if anyone out there could invent one. DXTER IS THE REAL-LIFE TRICORDER One team has come out victorious; a family team with the name of Final Frontier Medical Devices from Pennsylvania in the USA. The non-profit foundation managed to get hold of the $2.5 million prize fund, while the Dynamical Biomarkers Group from Taiwan came in second place and took home $1million.
The whole objective of the Qualcomm Tricorder XPRIZE competition was to come up with a handheld device that was non-invasive and which was lightweight, which was able to identify 13 different health conditions, 12 of which were diseases and the absence of disease, within 90 minutes to 24 hours and without additional help from any medical professionals. Vital health metrics that were required to be constantly monitored included heartbeat and respiratory functions. It was said that the winning device from the team was, in fact, more advanced that the fictional version from Star Trek. The competition started in 2012 and out of the 312 teams that started out, it was cut down to just ten teams. The two finalists had been revealed in December last year, and six were honored at the Los Angeles prizegiving ceremony. Dr. Basil Harris, an emergency physician, and brother George Harris, a network engineer headed the winning team. They designed DxtER, a device that had artificial intelligence, which they funded along with two other members of the family. They decided that one device wasn’t sufficient to be able to diagnose, accurately and quickly, various conditions in the patient and found they needed to link the device to a wealth of medical data. winner of a global competition meet dxter the reallife star trek tricorder
NASA just discovered the first food source for potential aliens
NASA just discovered the first food source for potential aliens
Searching for aliens is a tricky business. Most likely, the first alien life we discover will be hidden beneath miles of ocean on a distant world like Jupiter's moon Europa or Saturn's moon Enceladus.
That's why the best way to search for alien life today is to find pieces of the puzzle that make up the larger picture. In recent years, NASA has done just that with its Cassini spacecraft.
Cassini first discovered evidence of a vast ocean on Enceladus by spotting plumes of water vapor jutting out of Enceladus' surface. Now, the Cassini team has announced that this distant ocean contains hydrogen.
Hydrogen is the most abundant element in the universe, so it might not come as a surprise it exists in the oceans of Enceladus. However, this hydrogen could serve a very important purpose: food for alien microbes.

That's exactly what some of the hydrogen here on Earth does — it feeds microbes that live on the seafloor in extreme environments where sunlight can't reach. So, the discovery of hydrogen on another water world is extremely exciting.

NASA ANNOUNCES MAJOR PRESS CONFERENCE ABOUT ITS SEARCH FOR LIFE BEYOND EARTH
EUROPA OCEAN WORLD
Space enthusiasts from all over the world have been left giddy with excitement after NASA has issued another cryptic message announcing a press conference this Thursday that will reveal new discoveries about ‘water worlds’ within this solar system.
While the press release didn’t give much away about the content of the planned press conference, it did make reference to ‘future ocean world exploration’ which is said to include NASA’s upcoming Europa Clipper mission which will launch in the 2020s and will focus on ‘the broader search for life beyond Earth.’ The discoveries that will inform this press release are believed to come from data derived from the Hubble Space Telescope and the extraordinarily successful Cassini mission which has been examining Saturn and its numerous satellites for the past thirteen years. The wording of the press release suggests that NASA will not announce that they have actually discovered life beyond this planet as of yet. However, the specific and direct reference to Jupiter’s Europa moon seems to indicate that the space agency believes that it is very likely that the icy moon is hosting extra-terrestrial life.
Europa is one of Jupiter’s sixty-seven moons.and has long been believed to be one of the best candidates in this solar system capable of supporting extra-terrestrial life. Europa is a relatively small moon, a little smaller than Earth’s moon, with a thick layer of ice covering the surface and a huge liquid ocean. It is estimated that Europa’s ocean is almost ten times deeper than the oceans on planet Earth and that the reasonably small moon might hold as much as two to three more times the volume of liquid water than this planet. The presence of water is deemed to be one of the most important elements when it comes to establishing the existence of life. The new information about Europa will certainly enthrall space enthusiasts, especially if it involves moving closer to establishing the existence of life outside of planet Earth. The announcement will be made to the public at 2pm ET (6pm UTC) Thursday 13 April 2017, and you can watch the whole thing live below. nasa announces press conference about search for life beyond earth.....
An edible water bottle that could save the planet. Meet OOHO!
Ooho is a container made of an edible algae membrane.
Created by London-based industrial design students Rodrigo García González, Pierre Paslier, and Guillaume Couche, the Ooho is a blob-like water container made out of an edible algae membrane.
The design is inspired by how liquid drops form and how egg yolks work. The container is created using a culinary technique called “spherification” and the water is held inside by a double gelatinous membrane. The gel around the water is created from brown algae and calcium
The designers envision the product as something that people can create in their own kitchens. People can modify and innovate the recipe and CIY (“Cook-It-Yourself”) the Ooho on their own.Similar to Wikipearl, the Ooho promotes the use of natural and edible packaging. It proposes a simple and cheap, biodegradable and edible alternative to plastic bottles and aims to eliminate the inconceivable amount of water bottles that end up in landfills.
Ooho is a Lexus Design Award 2014 winner and will be on exhibit at Milan Design Week.....
Science isn't a matter of opinion

The current state of scientific discussion within society is beginning to resemble Issac Asimov's famous quote that ignorance is "… nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge.' "
This emerging paradigm is likely caused by a combination of factors. The first is inadequate science education, the second an intersection of hyper-partisanship and cognitive bias, in which people wield scientific data only when it suits their argument. In this way, the input of researchers is not only commonly dismissed in policy discussions, but often denigrated as "partisan screed of the biased liberal elite" or "tool of systemic oppression" when it runs contrary to the speaker's preconceived notions.
These statements could not be further from the truth. More to the point, the body of knowledge built by the scientific community is so interwoven and complex that one could not possibly cherry-pick the things that support their conclusions without committing to a massive number of logical paradoxes.
To illustrate my point, the body of knowledge upon which the assertions that man-made greenhouse gases are responsible for warming our atmosphere is based on the law that matter (specifically carbon dioxide and other gasses) absorbs and re-emits light as described in an equation derived by Svante Arrhenius in 1896.
[A march for science steps into the unknown]
If the case were made that warming of Earth's atmosphere is independent of the increasing levels of greenhouse gases, it would mean that his equation was wrong. But that equation also governs our understanding of chemistry, as we use the amount and wavelength of light that a chemical absorbs to determine its structure, which we cross-reference for accuracy by subjecting the chemical to intense magnetic fields in various instruments and observing its behavior. If Arrhenius was wrong, then these other systems would also be wrong. This implies that our understanding of magnetism and electromagnetism is flawed.

China has handed a 600-ton patrol ship over to Pakistan’s
China has handed a 600-ton patrol ship over to Pakistan’s maritime safety authority in Guangzhou, Guangdong province, reported the Chinese newspaper People’s Daily.
Among other things, the ship will be used to safeguard Pakistan’s maritime interests.
The new ship, just the third of its kind, was built by China Shipbuilding Trading Company Ltd. (CSTC) and China State Shipbuilding Corporation (CSSC) Xijiang Shipbuilding Co., Ltd. Its two predecessors have already demonstrated their reliability and excellent performance during visits and exchanges, joint drills, maritime rescue and other missions in Pakistan.
Pakistan’s maritime safety authority expressed appreciation for the quality of the ships and for sound cooperation with Chinese ship manufactures, who have promised to provide after-sale services, the report said.
“The ships are key to consolidating China-Pakistan relations, protecting Pakistan’s sea transportation and pushing forward the China-Pakistan Economic Corridor and Belt and Road Initiative.”
