World’s Longest Running Synchrotron Light Experiment Reveals Long Term Behaviour Of Nuclear Waste Materials

Longest ongoing synchrotron light experiment in the World unveils behaviour of nuclear waste materials that are long term

University of Sheffield researchers, in collaboration with the Diamond Light Source, are the forerunners in studying and understanding gradual transformations in nuclear waste materials. Their experiment just reached a major milestone of 1000 days which makes it the world’s longest running synchrotron light experiment.

Led by Dr Claire Corkhill from the University’s Department of Materials Science and Engineering, the research has utilised the world’s best facilities at the Diamond Light Source to study the long-term behaviour of cement materials used in nuclear waste disposal through the synchrotron experiment.

Dr Corkhill explained that these cements are used to securely lock away the radioactive elements present in nuclear waste for a time period of more than about 10,000 years, hence it is vital that the properties of these materials are accurately predicted in the future. She also added that the exclusive provision at Diamond has enabled them to follow this reaction in situ, for a period of 1000 days and the data received from this study is already helping them recognize exact phases that will securely and safely lock away radioactive elements in a time span of 1000 years’ which is something they would not have been able to determine otherwise.

Dr Corkhill also stated that she has definite plans to return to Diamond Light Source to investigate and observe the reaction of these particular phases with uranium, plutonium and technetium on a single beamline of the X-ray absorption spectroscopy.


The Director of the Immobilisation Science Laboratory and co-investigator of this particular research, Professor Neil Hyatt, said that they all are very enthusiastic to be chosen to partake in this synchrotron experiment as the first ever consumers, in this world’s best facility and capability and are grateful to the people at the Diamond Light Source, Dr Chiu Tang, Dr Sarah Day and Dr Claire Murray from I11 in particular, for all the support they provided in helping all their experiments seeing the light of day and for being the perfect curators of their samples for a period of 1000 days. He added that they were very pleased that this 1000 day milestone established firmly their long-term association between the University of Sheffield and the scientists present at the Diamond Light Source.

Dr Corkhill is, at present, keeping an eye on the alterations in eight nuclear waste cement materials by determining the high resolution diffraction patterns at Diamond Light Source on the I11-1 beamline. Diamond Light Source happens to be UK’s national synchrotron science facility which was financed as a joint venture by the UK Government with the help of the Science & Technology Facilities Council (STFC) in collaboration with the Wellcome Trust. Dr Corkhill’s results and findings are currently being utilised to provide support to the ongoing safety case development meant for the UK Government policy to get rid of nuclear waste in a disposal facility that is geologically deep.
Scientists at Diamond plan to construct five more beamlines for these synchrotron experiments by 2020. But for now, there are no plans to put a stop to this experiment and it will in all probability continue to break records until the materials don’t change anymore or the space is required by another space.

The Most Secure Way To Unlock Your Phone, Revealed

Unlock Devices – Shoulder Surfing Attacks
 
Researchers have warned that users should stop utilising patterns to unlock their devices. According to latest study it has been observed that it seems much easier for people to glance over your shoulder while the user unlock his phone and memorise a pattern than a passcode.

According to the researchers, the so-called `shoulder surfing attacks’ could be cool for a criminal to intend and execute, though the user can protect themselves by turning to a PIN code and on increasing its length from four digits to six. They acquired more than 1,000 volunteers to pose as attackers, challenging them to memorise a range to unlock authentications of four and six digit PINs and four-and six-length patterns with and without tracing lines, by observing a victim over their shoulder from a variety of angles.

The two handsets utilised in the study were the 5-inch Nexus 5 and 6-inch OnePlus One which according to the researchers were identical to a wide variety of displays and form factors available in the present market for Android as well as iPhone. Moreover the researchers also measured single and various views for the attacker with two different hand positions for the victim for single-handed thumb input as well as two-handed index-finger input.
 
PINs – Most Secure
 
They observed from the research that four-length patterns having visible lines had been quite easy to unlock owing to shoulder surfing than any other means to unlock authentication that was tested. Researchers from United States Naval Academy and the University of Maryland commented that they observed that PINs were the most secure to shoulder surfing attacks and though both types of pattern input were poor, patterns without lines provided greater security.

Moreover the length of the input also tends to have an impact and longer authentication seemed more secure to shoulder surging. In addition, if the attacker tends to have multiple-views of the authentication, then the performance of the attacker is greatly improved. During the experiments about 10.8% of six-digit PINs were successful to unlock after a single observation and this figure increased to 26.5% after two observations. Around 62.5% of six-length patterns having tracing lines on the other hand could unlock after a single observation which increased to 79.9% after two observations.
 
Shorter Patterns More Susceptible
 
About 35.3% of six-length patterns devoid of tracing lines could unlock after a single viewing which rose to 52.1% after two observations. The researchers stated that shorter patterns had been even more susceptible, adding that even individuals using fingerprint or face-scanning technology for the purpose to unlock their phones need to be wary of their discoveries.

They further stated that biometrics seems to be a promising advancement in mobile authentication, though they can be considers a reaauthenticator or a secondary-authentication device since individual tend to need to have a PIN or pattern which they could enter somewhat often owing to environmental impacts for instance, wet hands.

There are also instances of high false negatives rates linked with biometrics. Besides this user with biometrics tend to opt for weaker PINs in comparison to those without, signifying that the classical unlock authentication tends to be an important attack course going forward. From a separate research published earlier in the year, it was observed that most of the security device patterns can unlock within a span of five attempts.

Ask More Of Your Phone: Google Pixel 2

Google is all set to launch the next iteration of its flagship Pixel 2 smartphones this week. Tech enthusiasts and industry experts are holding the opinion that Google next offering will have enough features packed into it to win over the Apple’s iPhone 8. Here are some of the predictable features which are expected to be seen in the Pixel 2 to win over its competition and other gadgets are as follows:

Wide Angle Lens - It is worth noting that Google Pixel XL simply became world’s best camera on a smartphone last year. However it didn’t had the wide angle lens that time around, so it is being expected that Google will opt for some good wide-angle lens for its Pixel 2 devices. Secondly Pixel devices didn’t even have the ISO and shutter speed control which were sorely missed by the users.
Headphone jack – It is highly expected Google will finally give in the way just like Apple and it will get rid of lovely 3.5 mm headphone jack in order to make its device more slim. Almost every major flagship device is following the single-port ethos nowadays wherein users had make use of adapters in order to charge and listen to music on the go. Bluetooth headphones are the option but nobody likes them as much as manufacturers like them.

BoomSound – Just a few weeks ago Google acquired a massive part of HTC which has been critical in the development of the Google devices in the past. It is expected that new Pixel 2 devices will feature the BoomSound which has been developed by HTC and happens to offer incredible audio output from the external speakers. In simple words Pixel 2 devices will offer simply the best speaker audio rendition through the use of BoomSound technology in the upcoming Pixel 2 smartphones.

No Limit on GDrive Storage – Google won over the smartphone customers by offering one of a kind ‘Unlimited’ GDrive storage for pictures and videos on the Pixel devices. When most of the OEM and cloud storage providers are happily charging certain amount for extra cloud storage Google has simply done away with it. Better phones simply translate larger audio and video files which ultimately require larger storage. Some experts believe that Google will take everyone by surprise this year as well by offering unlimited GDrive storage to the Pixel 2 and Chromebook owners.

A flexible device – Google has taunted the users with its secretive next generation of the flexible technology. It is will suspected that Google might well go ahead and bring a flexible Pixel 2 device to the world. This would make 2017 best year in the smartphone innovation after years of stagnant development.

All of these features are merely speculation fueled by the recent development made by its rival and most importantly Apple’s iPhone 8. If Google Pixel 2 devices of 2017 do come with these features and or something better than these then it will surely give Apple’s iPhone 8 and other gadgets run for its money.

Biological Clock Discoveries by 3 Americans Earn Nobel Prize

The discoverers of the 'internal clock' of the body, Nobel Medicine 2017

The winners are Jeffrey C. Hall, Michael Rosbash, and Michael W. Young

US scientists Jeffrey C. Hall, Michael Rosbash and Michael W. Young today won the 2017 Nobel Prize in Medicine, "for their discoveries of the molecular mechanisms that control the circadian rhythm," according to the jury of the Karolinska Institute in Stockholm, responsible for the award. The prize is endowed with nine million Swedish crowns, about 940,000 euros.

Thanks in part to his work, today it is known that living beings carry in their cells an internal clock, synchronized with the 24-hour turns of the planet Earth. Many biological phenomena, such as sleep, occur rhythmically around the same time of day, thanks to this inner clock. Its existence was suggested centuries ago. In 1729, the French astronomer Jean-Jacques d'Ortous de Mairan observed the case of mimosas, plants whose leaves open during the day into the sunlight and close at dusk. The researchers discovered that this cycle was repeated even in a dark room, suggesting the existence of an internal mechanism.

In 1971, Seymour Benzer and his student Ronald Konopka of the California Institute of Technology took a momentous leap in research. They caught vinegar flies and induced mutations in their offspring with chemicals. Some of these new flies had alterations in their normal 24-hour cycle. In some, it was shorter and in others, it was longer, but in all of them, these perturbations were associated with mutations in a single gene. The discovery could have earned the Nobel, but Benzer died in 2007, at age 86, for a stroke. And Konopka died in 2015, at age 68, of a heart attack.

The Nobel, finally, was taken to Hall (New York, 1945), Rosbash (Kansas City, 1944) and Young (Miami, 1949). The three used more flies in 1984 to isolate that gene, baptized "period" and associated to the control of the normal biological rhythm. Subsequently, they revealed that this gene and others self-regulate through their own products - different proteins - generating oscillations of about 24 hours. It was "a change of paradigm", in the words of the Argentine neuroscientist Carlos Ibáñez, of the Karolinska Institute. Each cell had a self-regulating internal clock.

The scientific community has since established the importance of this mechanism in human health. This inner clock is involved in the regulation of sleep, in hormone release, in eating behavior and even in blood pressure and body temperature. If, as occurs in people working in shifts at night, the pace of life does not follow this internal script, can increase the risk of suffering different diseases, such as cancer and some neurodegenerative disorders, says Ibanez. The syndrome of fast time zone change, better known as jet lag, is a clear sign of the importance of this internal clock and its mismatches.

The Karolinska researcher sets an example with a 24-hour cycle, in which the internal clock anticipates and adapts the body's physiology to the different phases of the day. If the day begins with deep sleep and a low body temperature, the release of cortisol at dawn increases blood sugar. The body prepares its energies to face the day. When night falls, with a peak blood pressure, melatonin, a hormone linked to sleep, is secreted.

These inner rhythms are known as circadian by the Latin words circa, around, and dies, day. The scientific community now knows that these "around the clock" molecular dashes emerged very soon in living things and were preserved throughout its evolution. They exist in both single-cell life forms and in multicellular organisms such as fungi, plants, animals, and humans.

At the time of its discovery, Hall and Rosbash were working at Brandeis University in Waltham, and Young was researching at Rockefeller University in New York. Its recognition follows the tonic of the Swedish awards. Men have won 97% of Nobel prizes in science since 1901. In the category of Medicine, statistics improve slightly: 12 of the 214 women are awarded the prize: 5.6%.

Pixel 2, Home Mini and Pixelbook What You Need to Know

At an event on October 4, the Silicon Valley firm is all set to expose its latest gadgets comprising of latest phone. However before the event can take place, a consumer publication has got itself a series of images which displays the majority of what Google would probably launch. The following are what can be expected from the Google event together with its fresh line-up of gadgets:

Google makes hardware

Together with its search ability and drives in AI, Google is said to have moved firmly in the hardware area in the last few years. Moving away from its Nexus phone brand and trying to reinvest its attempts under the moniker of Made by

Google, the company has now released various high end gadgets. These comprises of its Pixel and Pixel XL phones, a mobile virtual reality headset known as Daydream, together with a Google Wi-Fi box and its amazon Echo voice assistant competitor, Google Home. Many have been expecting to see new repetitions of these devices at the forthcoming event of the company.

What’s the event holding?

The company had called another press conference; precisely a year after Google had released the Pixel, its first own-name branded phone. This would most probably see the overview of its latest hardware attempts though no one could be completely sure till it shows up. The event is said to take place at 9 AM PT in San Francisco and there would also be a press event that would take place at the same time in the UK. This would kick-off at 5PM and would also be live-streamed online

What would the latest phones look like?

Owing to the outburst of leaks the latest being from DroidLife, it is a known fact that the upcoming gadgets, Pixel 2 and Pixel 2 XL Android devices would have a same form factor to their predecessors. From the leaked images of the two phones, it displays a single camera on the rear, a fingerprint scanner together with colours ranging from light blue to white and black combo. DroidLife reported that the Pixel XL 2 a bigger screened version of the phone would have 64GB or 128GB storage and the price is from $849 to $949. The smaller gadgets Pixel is said to have the identical storage choice and is priced at $649 and $749. With regards to specs, the reported details are scarce on the ground presently. The Verge had reported that the XL would be having a 6-inch OLED screen, a Snapdragon 835 process with the potential of controlling the phone by squeezing it which had been introduced in the HTC U11. The company had spoken a lot about the Google Lens, a feature enabling a phone camera to comprehend what it tends to see, at the developers conference earlier in the year. It is also expected that the Pixel 2 XL would be having a much less of a bezel than the smaller product devices.

Google Home – Mushroom-Like Speaker

Google seems to be established in introducing smaller gadgets version of the Google Home if one is into voice assistants. Details of the Home Mini was made available by source, which is a mushroom-like speaker that tends to sit in one’s home , pay attention and chat with you. Similarly, Amazon provides a low-priced Echo Dot which tends to rival with Google. The price of the Home Mine is said to be around $49, with shades of silver, orange and dark grey featuring the Google Assistant. The company had mentioned that it is an AI company instead of a search giant and it would not be surprising for Google to disclose more update regarding its Assistant. The company desires its voice assistant to be implanted in several third-party gadgets as imaginable. It has reported that VR viewer DayDream of Google would be provided with an update and would be offered in various colours. Further details with regards to the interior of the device is not clear though it would remain to be a mobile VR viewer housing a phone and it would come at a price of $99.

Chromebook Pixel - PixelBook

According to some sources as informed to Android Police the re-born Chromebook Pixel gadgets will show up soon. A Pixel Chromebook would be launched according to Android Police had been confirmed in the latest series of report. The device has been dubbed the PixelBook and is said that the same would comprise of 128GB, 256GB and 512GB of storage and priced at £1,119. The original Chromebook Pixel had been released by Google in 2013 and had been revitalized in 2015 and has not launched a newer version since then. For several years, third-party vendors like HP and Acer have been proposing some cool Chromebooks. At this point of time not much is revealed. Android Police wonders that it could be born out of the Project Bison of the company that had been planned to be presented during the third quarter this year. We need to wait and watch for the forthcoming event of October 4 for the surprises in store by Google.
