Dino-era Rat-Like Fossil Claimed As Earliest Human Ancestor

Well, from our very childhood days, in schools as well as in colleges we have been taught that we humans are originated from the species called as apes, but a current discovery of  146 million-year-old new eutherian creature or species imply that homo sapiens ancestry comes has come from the family of rats, based on the new research. The fossil revealed on the Jurassic Coast of Dorset is supposed to be remains of one of the oldest mammals on the earth. The two teeth species are from small family, rat-like creatures that existed 146 million years ago in the shadow of the dinosaurs.

Dino-era Rat-Like Fossil Claimed As Earliest Human Ancestor

The research was detailed in the academic journal called as “Acta Palaeontologica Polonica” by the scientists and it was on air by November 7, 2017. Grant Smith, an undergraduate apprentice from the University of Portsmouth, who made the innovation, said that the invention is undisputedly the most primitive fossils of mammals fitting in to the line that led to human beings. “These rodents are also in relations to utmost living mammals which consist of: blue whale,” as stated by Smith.

Research lead instigator Steven Sweetman, who is a paleontologist at the University of Portsmouth, located in England, in an announcement stated by him, “Smith got not one but two moderately notable teeth of a kind. The revealed fossils are absolutely the most primitive eutherians known nevertheless in the fossil record. The teeth are extremely developed. As soon as I saw them I came to know straight away, that I was looking at remains of primitive and oldest Cretaceous mammals. ”

The scientists have named the species as Durlstotheriunm newmani and Durlstodon ensomi. The researchers said Durlstotherium was likely about the size of a mouse, while Durlstodon was as big as a juvenile rat. The teeth are highly advanced type which can pierce, cut and crush food. “The discovered teeths are also very worn, which suggests the rodents lived to a good age for their species,” added Sweetman. According to the researchers both the creatures were likely nocturnal. Durlstotherium fed on insects and Durlstodon ate plants. The duo animals lived in Mediterranean type climate.

Short Breaks Of Video Games During Work May Battle Stress

Feeling tensed at the time of working hours? Playing video games may assist, claims researchers who recommend that getting busy in such pleasuring activities during short break can assist workers revitalize themselves.

People frequently go through cognitive exhaustion associated to frustration, stress, and anxiety at work place. Those in safety-critical sectors, such as health care and air traffic control, are at an even superior jeopardy for cognitive exhaustion. This might result in errors. Given the quantity of time that individuals invest playing games on their tablets and smartphones, scientists needed to check whether casual playing of video game is an effectual approach to battle stress at workplace during short breaks.

Short Breaks Of Video Games During Work May Battle Stress

Scientists in the U.S. from University of Central Florida utilized a task based on computer to provoke cognitive exhaustion in 66 members, who were then provided a short break of 5 minutes. During the break, members were found either playing a casual video game dubbed Sushi Cat or sitting quietly in the testing room without utilizing a computer or phone. At various stages during the experiment, the scientists measured members’ cognitive performance and behavior (for instance: mood, stress level).

Those who decided to take a silent rest break said that they felt less occupied with work and experienced anxiety as a result. On the other hand, those who took part in the guided activity of relaxation witnessed reductions in distress and negative effects. Only the members who played video game said that they, after taking the break, felt better. “We frequently try to fuel through the day to get more job done, which may not be as effectual as taking some time to separate for a couple of minutes,” claimed a student doctor at the University of Central Florida, Michael Rupp, to the media in an interview.

“Individuals must make arrangement for short breaks to make time for an enjoyable and engaging activity, such as playing video games. This might help them revitalize,” claimed Rupp to the media in an interview. The survey was posted in the journal Human Factors this week, as per the sources having deep knowledge of this matter.

Study: Pokémon Go Helps Students to Develop Skills

Almost a year ago, the new augmented reality game, Pokémon Go, created a storm in the market. The game was addicting and was one of its kinds. And now, according to a latest research, playing Pokémon Go may assist students to enhance their communication abilities in classrooms.

Study: Pokémon Go Helps Students to Develop Skills

Scientists from the U.S. in Iowa State University targeted on providing students evenhanded authority to tools and assisted them construct multi-modal communication abilities. That intended not only employing technology to replace traditional classroom tools or guzzle information, but testing with innovative types of communication.

Slotting-in students via Pokémon Go, a game that lot of people are playing outside by now, also connects students and creates interest to their work, as per the scientists.

“It is essential to provide students genuine options that actually have meaning in their life. We require encouraging them to build up questions, investigate the answers and after that distribute the data in writing,” they claimed.

Pokémon Go, similar to many games, offers players with partial data or what scientists explain as “just in time learning.” Consequently, students have queries about how to advance to the next level or employ particular tools.

At the same time as enjoying the game with her own kids, Emily Howell, assistant professor, Iowa State University, witnessed that it might assist students with research and writing.

“Pokémon Go slots-in various stages of communication such as visuals, gestures, and directions, which crafts it a fine fit for the students in classroom,” Howell claimed.

Students see the Pokémon on their smartphone, the Pokémon is incorporated into a map and the students handle catching the Pokémon.

“Pokémon Go demonstrates the requirement to recognize multimodal text, which mirrors how we converse with other individuals,” Howell further added.

“We do not simply launch an email or text; we have a video conference or live chats. Teachers can anytime discover, to some extent, what students are by now doing, and arrive in multimodal state; they can strap up that curiosity of students and educate them about the potential of the tool,” Howell added.

In a nutshell, it has been proved that Pokémon Go is not only employed as a game but also to educate students.

Researchers Trap Surplus Photon Energy to Generate Solar Fuels

At present, many studies are focusing on the usage of renewable energy for various purposes in order to meet the energy demand across the world. A research team at the National Renewable Energy Laboratory of the U.S. Department of Energy has developed a photoelectrochemical cell that has the potential of capturing surplus photon energy that is generally lost to producing heat.

Researchers Trap Surplus Photon Energy to Generate Solar Fuels

With the use of a method known as Multiple Exciton Generation and quantum dots, the research team was capable of advancing the peak external quantum effectiveness to 114% for hydrogen generation. The push could notably drive the generation of hydrogen from the sunlight with the use of cell to cleave water at low cost and higher efficacy in comparison to the available photoelectrochemical approaches.

In 2011, a paper was published demonstrating for the first time how a multiple exciton generation enabled a solar cell to surpass 100% quantum efficiency by generating additional electrons in the electric current that the total photons inflowing the solar cell.

Matthew Beard said, “The key distinction here is that we captured the multiple exciton generation improvement not only in the electrical current but also in a chemical bond. We illustrated that the similar method that generates surplus current in a solar cell can also be utilized to generate additional chemical reactions.

The utmost hypothetical competence of a solar cell is restricted by how much photon energy can be transformed into functional electrical energy. The multiple exciton generation method takes benefit of the surplus photon energy to produce additional electrons and hence, extra electrical or chemical potential instead of producing heat. Quantum dots that are spherical semiconductor nanocrystals with a diameter of 2–10 boost the process of multiple exciton generation.

In the present study, the charge carriers, or the multiple electrons, that are produced via the multiple exciton generation method within the quantum dots are trapped and stored within the H2 molecule’s chemical bonds.

The chemical reaction that is directed by the surplus electrons showed a new path in discovering high-efficiency methods for producing solar fuels.

What is your opinion regarding this new way of producing solar fuels?

Traces of Planet Nine found out in solar system

Astronomers must have established a new world, concealed in our own solar system. And it must have been exposed by a group of astronomers, almost 60,000 who pulled out via images of rocks and might have discovered the inexplicable ‘Planet Nine’.

Traces of Planet Nine found out in solar system

The Australian National University’s astronomers are looking into 4 unidentified items, each of which might be an aspirant for an up-to-the-minute, as yet mysterious planet in our own solar system. The items were discovered by a terrestrial search that was encouraged by a T.V. program that inspired citizens, above 60,000, to decide on via more than 4 Million substance and observe whether there may be chances of a new world.

The hunt has by now revealed two trivial planets. That establishes that the move could finally stagger on the much-rumored Planet Nine, they say. Now you must be confused as to what is Planet Nine? Well, Planet Nine is a supposed world hanging about on the perimeter of our solar system. It has by no means been seen openly, but it has been theorized based on extraordinary gravitational samples that appear to propose something is out there, further than Pluto.

The national astronomers lent a hand exclude big fractions of the southern sky, overcrowding out seats where Planet Nine could be located. “We have supervised to discover a planet out to a depth of about 350 times the distance the Earth is from the Sun about the dimension of Neptune being in about 90% of the southern sky,” said lead researcher on the project Brad Tucker.

“With the assistance of thousands of devoted and enthusiastic volunteers separating through thousands of hundreds of pictures taken by the SkyMapper device, we have accomplished 4 years of systematic examination in less than 3 days. Toby Roberts, one of those astronomers, has made more than 12,000 categorizations.”

Now astronomers around the world will point telescopes at the unidentified objects to discover out whether the items belong to Planet Nine. If not, they will examine them for other small planets or asteroids. But for time being, the mere thought of existence of another planet is just chilling us out.

Evolution: Survival of the Friendliest

We have heard and learned from the beginning that evolution is nothing but the survival of the fittest. But it seems that it is other way around. Today, the real meaning of evolution has changed to survival of the friendliest. How? Let’s find out.

Evolution: Survival of the Friendliest

Games of life are not all violent fights. And you do not need brain to understand that survival is not a fight. Fighting may not be the best way. Even a single-celled bacterium has the ability to understand this.

  1. Kelly Clancy speaks about the “Survival of the Friendliest”. She explains the logic behind the evolution and its relationships past rivalry
  2. For instance, approximately 98% of species belonging in the bacteria category do not flourish outside colonies with mixed species.
  3. “Bacteria are not self-adequate: They’ve evolved in the presence of each other to be dependent on each other.” They have found specialization, division of labor, and cooperation.
  4. That specialization is a game-changer. You now need colleagues. If they do not flourish now, you will not thrive ever.
  5. In a type biochemical where the brains are not needed, also known as “social contract,” colonies of bacteria, like communities of human, have to control the “common good”
  6. For instance, “helper” species that “offer an ordinary good… may come to be protected from rivalry by the species that depend on them, as occurs with corals”
  7. Such mutually dependent logic of survival permeates biology (e.g., all trees, all “selfish genes,” all animals).
  8. Mankind is also deeply underprovided by itself (likely the most ordinary-goods-requirement and various-dependent classes ever). We control because we’re the most excellent cooperators
  9. Daniel Dennett refers this case as “free-floating rationales”: logic outlines that are natural in various cases but are not restricted in (or “aware” to) the players or elements occupied (they are distributed, free-floating, systemic, relational).

Well, these points surely state that evolution is not survival of the fittest but it means survival of the friendliest. Even in our everyday life we can feel this. We guess it is time to change the course of history. Do you agree?

Vital Signs Measurement Using Graphene Tattoo

The researchers, Nanshu Lu and Deji Akinwande, from University of Texas, Austin, have developed a health sensor that is bio-integrated and applied to the skin like a temporary “tattoo” to take vitals signs measurements. This graphene tattoo has a small form factor than usual sensors. The graphene tattoo has unique characteristics such as flexibility, that is, its atom-thick structure moves with the skin while the mechanical resilience bears the stretching and compression damage to the tattoo. Its conductive nature makes it a perfect non-invasive method for vital signs monitoring.

Vital Signs Measurement Using Graphene Tattoo

The tattoo is developed by placing an atom-thick layer of graphene on a copper sheet followed by graphene coating with a stretchy base layer polymer and copper etching. Further, the sheet is placed on an impermanent dissolvable tattoo paper for the future use. The graphene is designed into electrodes and spiral connections to bridge the gaps between them. The tattoos shape and flexibility builds a close contact with the skin surface and the sensor, which in turn eliminates the use of adhesives.

The graphene tattoo is applied by placing the temporary tattoo paper on the skin with water. The atom-thick circuitry of the sensor is held by the electrostatic forces that is strong enough for adherence and also makes the device take high-quality measurements. The vital signals produced by the heart, brain, muscle, skin temperature change, and hydration levels are measured. The measurement obtained from this small form factor is similar to the one from usual devices.

Thus, the scientists’ development of the bio-integrated technology, that is, the graphene tattoo, is creating a bright future for a more non-invasive and portable vital measuring device.

Turning Sunglasses into Credit Cards, New Invention by Visa

Have you ever imagined how it would be if your sunglasses functioned as credit cards? Yes, if it happened so, there would probably be no need of carrying your wallet all the way with you. And now, Visa has declared that it will start a new pilot program of their contactless payment by sunglasses, WaveShades. Thus, with such a facility, the sunglasses can even protect your eyes and when needed can be used to make cashless payments.

Turning Sunglasses into Credit Cards, New Invention by Visa

The pilot program will be initiated at the World Surf League’s 2017 Roxy and Quiksilver Pro Gold Coast contest, where Visa is one of the sponsors. The glasses looks like any ordinary pair of shades, the only exception to be the add-on contactless card that makes it possible to utilize the sunglasses as a means of contactless payment approach.

The WaveShades are entrenched with payWave technology owing to which they function in a similar way as your phone may when addressed to a contactless payment system. Taking into consideration the bulky profile of sunglasses, there are fewer chances for anyone to lose them, and also the glasses are likely to be on the face of an individual for most of the time during the day. It’s an interesting idea, and in order to grab the attention of the people around, Visa just gave away selected pairs of sunglasses that were pre-loaded with $50 that could be spent at the festival.

This is quite similar to the concept of the Microsoft Band 2 that involves the capability of buying Starbucks drinks directly via the wearable device when the wearer is out on a run. This can be a good option of carrying your money safely with you in high-theft surroundings. But, the question here is, what if someone steals these glasses, how would you prevent them from spending your money?

3D-printed bacteria make graphene-like materials

We have seen houses, foodstuffs, and many other things being made using a 3D printer. But have you ever thought about a life form such as bacteria been printed using a 3D printer? This very thought of printing life forms can be surprising, but that’s what technology is about. Using the 3D-printed bacteria, the scientists have made a modified version of the graphene-like material.

Bacteria used to build a material that resembles graphene with similar properties using a printer can prove to be a turning point in the 3D printing world. For testing the bacteria’s activities the researchers placed the bacteria on a sheet of graphene oxide, which the bacteria reduced by metabolizing, by pulling the oxygen atoms from the sheet together.

According to Anne Meyer from the Delft University of Technology, Netherlands, the reduction process of the graphene oxide using bacteria is preferred rather than the chemical processes as it is cost effective as well as eco-friendly. The bacteria can reduce the sheet of graphene oxide using sugar water and a temperature condition adjusted to about normal room temperature. Though the quality of the chemically-processed graphene version is better than the bacteria, it has a number of cones. So, this is where 3D printing comes into play to enhance the reduced graphene oxide quality.

With the help of 3D printer, the researchers printed a line of bacteria at 1mm distance from each other onto a surface. They added the E. coli bacteria in a gel made from algae and printed it onto a dish containing calcium ions. When the gel comes in contact with calcium, it solidifies so that the bacteria stay in place. After E. coli, its bacterium Shewanella oneidensis turn to prove its properties. The major concern is to maintain the shape, properties, and form of the bacteria even after been squeezed out of the 3D printer muzzle. The precision in the spreading of the 3D printed bacteria is a must while carrying out the process.

Now the researchers are looking forward to develop small conductive wires into the graphene oxide surface while the rest of the surface remains non-conductive. The use of bacteria to convert silica to silicon and iron oxide to iron is been carried out so that it is possible to sue this technology in converting the lunar dust substances as well.

Currently, this technology will be presented in April 2017 at the Microbiology Society’s annual conference, Edinburgh, U.K.
