Google AI can now write Wikipedia articles by itself

GoogleAI

The team behind the Google AI (Artificial Intelligence) bot revealed that their new software application is a capable generating article like Wikipedia. The software is capable of summaries an article by collecting pieces of information and images related to a topic from the internet.

A paper presented at ICLR (International Conference on Learning Representations) states that it is really a difficult task to summarize an article based on the information collected from the online resources. There are many top MNC’s investing a lot of time and money developing software which can summarize on its own. Salesforce could train its software to collect information’s and present it in a nutshell which is not so easy.

One major problem with AI generated sentences is it is short and simple than how humans do. Google AI perform slightly better in this problem as it could write longer sentences.

The below image is an example to show the difference between AI bot generated summary and Wikipedia page. The paragraph shown in left is an AI generated one and the right one is taken from Wikipedia page.

Google AI

The AI generated sentences are difficult to read as it lacks capital letters, grammar, and formation. Overall, we should still appreciate its work as it is still human-readable. The summarization done by AI is much longer than that of Wikipedia page, but with continuous improvement one day it can reach the same level.

The software uses an abstractive model where long sentences are broken into shorter one and summarize it. The software currently searches only for the top 10 search list from the internet to write on a topic. Thus, the credibility of writing which the AI does completely depends on the how accurate the contents of the top 10 web pages which it refers.

The team behind this great achievement of Google AI said we still have a long way to go in the development of AI and they are continuously working on it.

Meditation and yoga best medicine for body and mind

Yoga & Meditation

As we all know that “Health is wealth”. If you have health you have the most precious blessing in the world. There are many ways to get health but yoga and meditation are best for health. It is reported by many people that they get physical and mental health benefits through yoga and meditation.

This is not only stated by the people; it is proved by the researchers also. And a new article which is published in “Frontiers in Human Neuroscience” stated that yoga and meditation have a positive effect on mind and body. They found these results by an experiment which they have done on the participants who practice yoga and meditation for 3-months. And the researchers found that it put the positive effect on (BNDF) signaling, the cortisol awakening response (CAR) and immunological markers. And this also enhanced subjective well-being.

The study examined the participant before and after practicing yoga. And the results show the positive effects of the yoga and meditation on the mental and physical health of the participants. The participants practice meditation daily and also yoga along with vegetarian diet. The researchers also observed the relationship between yoga and meditation with depression and anxiety and the result was the yoga and meditation eliminate the anxiety and depression. The mindfulness is also increased in the participants of this research. These practices play a vital role
in mood regulation, stress response, immunity, inflammation, and metabolism.

The research team said that they have observed in their study that these practices have a positive link to increase flexibility and well-being.“The observed increased BNDF signaling possibly related to enhancing neurogenesis and/or neuroplasticity, increased CAR likely related to enhanced alertness and readiness for mind-body engagement, and increased anti- and pro-inflammatory cytokines possibly indicating enhanced immunological readiness.” Said by Dr. Cahn.

About positive effect of yoga and meditation to reduce depression Dr. Cahn further said: “An intriguing possible link between the effects on BNDF and the CAR is hippocampal functional integrity since increased BNDF levels due to physical exercise has previously been shown to relate with hippocampal neurogenesis and likely relate to its positive effects on well-being and depression.”

So, yoga and meditation both are best for both mental and physical health and it also enhanced flexibility and bring positive effects on people who practice both of these best health exercises.

Bigger Honey bee colonies have quite combs than smaller ones

honeybee

It is a common a belief that as bee colonies getter bigger, more the bees buzzing sound. But the latest study conducted by researchers from Cornell University reports that bigger honey bee colonies make less noise than smaller ones.

Michael Smith, from Cornell University, says, “The surprising result was that—and at first I thought something must be wrong—when there are more bees on the comb, the vibrations are actually reduced”.

Studies reveal that bees vibrate to communicate with other bees among its colonies. They perform a waggle dance to pass the message among the comb regarding the location of flowers. Queen bees also use the same way of dance vibrations to communicate with other queens. But to convey the message vibrations efficiently, the noise in the comb should be reduced.

To study the exact noise level, Smith with the help Po-Cheng Chen who built chips to measure vibrations in three dimensions using an accelerometer. The chip can absorb 800 samples of vibration in one by eight of a second.

Chen and Smith then placed the chip near a comb with different colony size, such as entire colony, half colony etc. They even performed the same studies with an entire colony at different times of a day. The number of bees in and out of a comb varies at a different time a day.

Smith also tested whether combined weight of bees reduces the comb vibration. Plain sheet wiggles more than a piece of paper with paper clips. For this, he added some dead bees to comb to see how it has any effect on vibration. From the detailed research, Smith says the additional bees “had absolutely no effect whatsoever on the comb vibrations, which showed us that the bees are actually doing something to damp these vibrations,”

The research shows that the superorganism such as bees, ants can overcome the physical obstacles in their own ways. The National Science Foundation, the Andrew W. Mellon Foundation, and the Garden Club of America funded the work.

Reports shows, Facebook has zero tolerance to those pages and account which spread such contents online.

Facebook acquires Confirm.io – an ID verification startup.

Confirm.io

Facebook Inc is acquiring Boston based software company – Cofirm.io which specializes in authenticating government-issued identification cards, the two companies said on Tuesday. The software helps to understand more about who purchases the ads on its network.

Recently the US. lawmakers expressed their fear on Facebook’s limited source to track its advertisement buyers. Social media advertisements influence the election-related campaigns in a huge way.

Confirm.io, a Boston based privately held company shared this news through their official website. The acquisition will take three years to integrate this technology with Facebook to keep its users safe.

Facebook through its official website confirms “technology and expertise will support our ongoing efforts to keep our community safe.”

As per the report shared by Reuters, Confirm Inc employees will continue their operations from Facebook Boston office. Terms and conditions of this acquisition are yet to be revealed.

Facebook has earlier suspected Russian agents had been paying to influence the electorate during 2016 presidential election. As a precaution to these activities, Facebook has decided to have more hold on its advertisement buyer’s identity.

The company later said it would begin requiring organizations running election-related ads to confirm their identities.

With a Facebook page and credit card, an advertiser can purchase the ads as per his wish. The social media giant has more than 6 million advertisers all over the world.

Confirm.io says that its technology will ask for proof of identity for online transactions made by the users which could bring down fraudulent activities.

Blinking dead stars to chart way for Space Station

Space Station

An experiment by International Space Station demonstrated that blinking dead stars can help on charting the path for Spaceships. During a meeting of the American Astronomical Society, researchers with the SEXTANT (Station Explorer for X-ray Timing and Navigation Technology experiment, SEXTANT) reported this experiment. The technique works like a GPS.

Pulsars are another name for Dead stars. They emit beams of radiation that regularly sweeps past our Earth like a lighthouse. Tackling these radiation beams help the space station to find its exact location in the space. This works like how GPS uses the satellite signals to determine your position of your mobile device. Thus, a space station no longer needed to rely on radio telescope communication to determine its coordinates. Radio telescope communication gradually gets inaccurate as the spaceship move from earth.

With the help of 52 X-ray telescopes SEXTANT measure the signals from five pulsars. Astronomer Keith Gendreau of NASA’s Goddard Space Flight Center in Greenbelt, Md., reported that with the help of these signals, researchers were able to locate SEXTANT’s position.

On Earth, knowing your location within 10 kilometers isn’t that impressive — GPS can do much better. But “if you’re going out to Pluto, there is no GPS navigation system,” Gendreau said. Thus, when we travel far from earth pulsar navigation will help us to estimate the positions with less effort and high accuracy.

Virtual Reality with Magnetic Skin Sensor

Magnetic sensor

Leibniz Institute for Solid State and Materials Research(IFW) and Johannes Kepler University Lin(JKU) have developed a magnetic sensor which is extremely thin and can be worn on the skin. People are very familiar with “augmented reality”: a computer-generated virtual reality with the success of Pokémon Go game. The electronic magnetic sensor will enable touchless manipulation of both physical and virtual objects.

At first glance, the glossy little gold bracelets looked like a modern tattoo. But in this very thin and invisible like foil that sticks to the palm like a second skin. The magnetic fields provide a feeling of “Sixth sense” with the help of sensors. These sensors enable people to access not only the physical world but also merely embedded with emotions, such as how a smartphone and control day to day objects.

For the first time, physicist and his team –  Prof. Oliver G. Schmidt at IFW Dresden and Prof. Martin Kaltenbrunner in the Soft Electronics Laboratory at JKU Linz -demonstrated that the magnetic field sensors can identify and process body movement in a room with a stable magnet. “Our electronic skin traces the movement of a hand, for example, by changing its position with respect to the external magnetic field of a permanent magnet,” explains Cañón Bermúdez of HZDR, the lead author of the study. “This not only means that we can digitize its rotations and translate them to the virtual world but also even influence objects there.” Using this technique, the researchers managed to control a virtual light bulb on a computer screen in a touchless way.

Tesla Roadster into the space with most powerful rocket

Elon Musk

Elon Musk the CEO of Space X is planning to launch the world’s most powerful rocket by the end of this month. Falcon Heavy was successfully launched from the Kennedy Space Center in Florida. Falcon Heavy will be carrying Elon Mask’s electric car Tesla Roadster.

Falcon Heavy will be tested on 27 engines. There are three recyclable sections which help Falcon Heavy to return to earth after its use. The launch and shutdown will be testing the technology expense of Space X.

The 2500 tons of 18 Boeing 747s will be burned during the launch of this huge rocket. The Falcon Heavy has a capacity to expose 63,500 kilograms of cargo from the earth. Elon Musk founded Space X in 2002. The company’s major missions are aimed at the cost-effective space carriers. This test is the biggest mission of Space X.

Last month, a picture of the Elon Musk’s 2008 model Tesla Roadster’s car revealed in the rocket. Elon Musk also revealed the reason for the inclusion of this extraordinary commodity in the rocket. Usually, the concrete or the rolling boats will be used as a burden during the test flight. Elon Musk says that he decided to leave his personally attached thing with the rocket.

If all goes well, the Falcon Heavy will fly from the earth. Two mission-packed rockets will be rolled back to Earth before the spacecraft outer space. The rockets are planned to return to Cape cannon after its mission. A part of the car will be separated from the main part of the rocket and returned to Earth. Elon Musk’s car will be returned in a deserted part of Pacific Ocean.

The scientists are waiting for the launch of the world’s most powerful rocket for testing and unprecedented retreats.

Scientists discover giant burrowing bat fossils in New Zealand

Scientists discover giant burrowing bat fossils in New Zealand

The researchers have found giant burrowing bat fossils in the South Island of New Zealand on Thursday that lived millions of years ago. The researchers belonging to the University of South Whales and the international scientists found the bones as well teeth of the extinct bat. The fossil remains of the burrowing bat reveal that it was thrice the size of an average bat and could walk on all the four legs.

The fossil remains of the bat, found in St Bathans in South Island’s Central Otago, are said to be dated back to an estimated period of 16 to 19 million years old. The study is published in the journal Scientific Reports.
The fossils of the burrowing bat weigh about 40 grams and make it the biggest burrowing bat which has been discovered to date. The findings reveal that the peculiar bats did not fly and walked on all four legs while searching for animal food or plants hidden under the tree branches or leaves. The name given to the giant burrowing bat is Vulcanops jennyworthyae, derived from the research team member Jenny Worthy who discovered the fossils and the Roman god of fire and volcano.

The burrowing bats are closely related to the South American bats. The burrowing bats found in New Zealand have a varied diet, including invertebrates like spiders and some other insects. The giant teeth of the Vulcanops jennyworthyae suggest that its diet was different and included more of vertebrates and plants.
Paul Scofield, the co-author of the study and a senior curator of natural history at the Canterbury Museum, said that the South American relatives of these bats lived alongside the iconic species in New Zealand like Moas, Kiwi and Tuataras. But on the other side, these species evolved in a way more complex community.

For survival, the Vulcanops jennyworthyae consumed of spiders, insects and weta as well. A weta dominates the territory of New Zealand and is a common name given to 70 different species. The bats utilised their big sized teeth to consume both plant material and smaller version of vertebrates which is similar to its modern cousins in South America. But still, the bats dominating Australia do not have the same diet.

The cooling and drying trend of New Zealand for an extended period of time could have caused the extinction of many bat species thriving in this area, leaving just two species in the modern fauna of New Zealand. Thus, the humans introduced some other varieties of bats in this area to increase the diversity. And now, the latest study shows on the prehistoric burrowing bat gives evidence that a wide diversity of bat species lived in the Gondwana supercontinent many years ago.

Frozen embryos for IVF are as good as fresh ones

Frozen embryos for IVF are as good as fresh ones

The researchers from Ho Chi Minh City, Vietnam, and Adelaide, Australia conducted a study and have discovered that infertile couples can now have a child by using freezing embryos. According to the study, frozen embryos used during in vitro fertilization (IVF) give a similar result like the use of fresh embryos.

The study is published in journal The New England Journal of Medicine. The researchers found a higher chance of having a child by using fresh embryos during in vitro fertilization. And when the result of this study was compared, the results showed that pregnancy and live births rates were similar in a group of in vitro fertilization women implanted with frozen embryos compared with fresh embryos.

The researchers conducted the study by selecting 800 infertile women, not related to polycystic ovarian syndrome (PCOS). As per results, about 36 percent the women who completed the first cycle of IVF got pregnant by frozen embryos techniques while in the fresh embryo group, the figure was 32 percent.

Dr Lan N. Vuong, from the Department of Obstetrics & Gynecology, University of Medicine and Pharmacy in Vietnam and the lead author of the study stated that the frozen embryo techniques are now growing rapidly in fertility clinics all across the globe. The research is thus very important for fertility clinicians and researchers and for those couples who are hoping to have a child.

Professor Ben Mol, from the University of Adelaide’s Robinson Research Institute, said that this new study shows that the infertile women not related to PCOS have similar live IVF birth rates from frozen embryos technique. This is important news for the infertile women across the globe, he further said.

Dr Vuong said the results are based on a particular freezing method called Cryotech vitrification, and there are low chances that the method will work with all embryo freezing methods or not. So the researchers will compare the pregnancy chances and live birth rates of this method with other freezing embryos techniques. Besides this, the method is considered to be one of the most effective, easiest and safest method of preserving oocytes and embryos.

However, the researchers say that in case of a large population, this method may not be effective to increase the chance of live birth like fresh embryos. Thus, the researchers are now conducting the further study so that it can be used in all fertile clinics worldwide as infertility is one of the major issues in the world.
