Report: 4-inch ‘iPhone SE’ and small iPad Pro will be revealed on March 21

According to multiple sources, Apple will announce a new 4-inch iPhone and new 9.7-inch iPad on March 21 and not on March 15 as previously reported.

The Korean website UnderKG was the first to report Apple’s decision to push back the event by a week.

And now BuzzFeed‘s well-connected John Paczkowski has confirmed the date change to March 21. Apple blogger Jim Dalrymple from The Loop, who’s been privy to top-secret Apple information, also corroborates Paczkowski’s report.

Mashable has reached out to Apple for comment, but the company declined to comment on rumor or speculation.

As per previous rumors and reports, Apple will reportedly unveil a new 4-inch iPhone SE. The new small-sized iPhone will be the first time Apple’s added a new 4-inch iPhone to the lineup since the iPhone 5C was released in 2013.

It’s believed the iPhone SE will retain a similar look to the iPhone 5S and possibly come in ahot pink color. The display’s glass will be ever-so-slightly curved on the edges, like on the iPhone 6 and 6S, though. It will reportedly come with the iPhone 6S’s A9 processor and M9 motion co-processor and a Touch ID fingerprint sensor for security and Apple Pay.

An earlier report said Apple would go with an 8-megapixel camera, but that appears to have changed as well. KGI Securities analyst Ming-Chi Kuo’s latest report claims the iPhone SE will have a 12-megapixel camera just like the iPhone 6S and 6S Plus. Kuo has a history of accurately leaking specs for new Apple products before their official announcement.

Though the iPhone SE won’t support 3D Touch, the pressure-sensitive technology embedded into the iPhone 6S and 6S’s display, it will support Live Photos.

Alongside the new iPhone 4-inch iPhone SE,

Apple is also expected to unveil a new 9.7-inch iPad Pro.

Apple is also expected to unveil a new 9.7-inch iPad Pro. Previously thought to be the iPad Air 3, the new tablet will be be part of the new iPad Pro family.

Like the 12.9-inch iPad Pro, the smaller iPad Pro will have a new design with four stereo speakers, the new Smart Connector for connecting accessories like a Smart Keyboard, and support for the Apple Pencil.

It’s unclear if Apple will discontinue the iPad mini and iPad Air. It’s likely that Apple will simplify its iPad lineup; 9to5Mac’s Mark Gurman says Apple is slowing down production for the iPad mini and “the iPad mini 2 and first-generation iPad Air are likely to be discontinued” when the new 9.7-inch iPad Pro launches.

Apple is expected to send out invitations for its upcoming event in the coming days. In the meantime, would you buy an iPhone SE or a smaller iPad Pro?

Entire science community was surprised last month whentwo Caltech astronomers claimed that they have foundninth planet of our solar system, approximately 20 timesfurther than Neptune. Now, NASA’s Cassini probe is goingto help astronomers locate the elusive planet far beyondthe orbit of Pluto.

Presence of Planet Nine hypothesized by Caltechastronomers Mike Brown and Konstantin Batygin is based on modeling, not directobservations. But the duo predicted that the search of the elusive planet can benarrowed with the help of some good quality telescopes.

Another team of astronomers stated that the possible ninth planet with a mass 10times that of earth could affect other planets’ motions. They said observations theyhave made are based on data from Cassini probe. It guides researchers where exactlyto search for the elusive ninth planet, the astronomers added.

The Cassini probe of the NASA has been studying the gas giant Saturn and its naturalsatellites since its arrival in 2005. The spacecraft has already captured manybreathtaking images of the planet and collected important data about it and its moons.The information sent by the probe to a team of scientists here on earth has been usedto create a model of the solar system that can track the movement of its largest bodieshovering in the observable universe.

Caltech astronomers predicted the presence of Planet Nine by observing orbits of sixrelatively large space bodies from Kuiper Belt. Many scientists are hopeful that theremay be a hidden planet. But, there are some space experts too who think theobservations by astronomers could be wrong. Now, only observational evidence cansettle the debate and prove whether our solar system has nine planets or not.

How an MIT team created a warning system for rogue waves

A new way of predicting the onset of rogue waves, also known as killer waves, has been developed by researchers at Massachusetts Institute of Technology (MIT).

Until now, efforts at predicting them were limited to costly, inefficient, and time-consuming computer models that aimed to map out every individual wave in a body of water.

This new method, published Feb. 11, 2016, in the Journal of Fluid Mechanics, is simpler, easier, and faster. It aims to give sailors and sea-platform workers a window of two to three minutes to prepare, including shutting down vital systems.

“It’s precise in the sense that it’s telling us very accurately the location and the time that this rare event will happen,” said coauthor Themis Sapsis, the American Bureau of Shipping Career Development Assistant Professor of Mechanical Engineering at MIT. “We have a range of possibilities, and we can say that this will be a dangerous wave, and you’d better do something. That’s really all you need.”

The new tool, which takes the form of an algorithm, hunts through data collected about surrounding waves, sifting for signs of clusters that could coalesce and crest into one of these behemoths.

By considering the length and height of a wave group, the new tool can calculate the probability of it mutating into a rogue wave.

“Using data and equations, we’ve determined for any given sea state the wave groups that can evolve into rogue waves,” Dr. Sapsis said in an MIT news release. “Of those, we only observe the ones with the highest probability of turning into a rare event. That’s extremely efficient to do.”

He contrasts this to previous efforts, which have adopted a “leave-no-wave-behind” approach, whereby they have aimed to provide a high-resolution simulation of the entire surrounding ocean surface, thereby keeping a beady eye out for suspicious activity of a rogue-like nature.

But the computer power required to run the necessary equations, not only for every wave, but also for the interactions between them, is considerable, demanding clusters of computers working in tandem.

“It’s accurate, but it’s extremely slow — you cannot run these computations on your laptop,” Sapsis said. “There’s no way to predict rogue waves practically. That’s the gap we’re trying to address.”

The new capabilities developed by Sapsis and his team built on previous efforts, whereby they had noticed that while most waves plough through the ocean single-mindedly, heedless of those around it, some roam in packs, toiling through the water in unison.

Further research led them to understand that some of these groups focus, or exchange, energy, in a way that ushers in the formation of a rogue wave.

“These waves really talk to each other,” said Sapsis. “They interact and exchange energy. It’s not just bad luck. It’s the dynamics that create this phenomenon.”

By analyzing the length and height of wave groupings, the researchers were able to produce an algorithm capable of predicting which were most likely to create the monster waves.

In order to take advantage of this new technology, ships and ocean-going platforms will need high-resolution scanning technologies such as LIDAR and radar to allow constant monitoring of the surrounding waves.

“If we know the wave field, we can identify immediately what would be the critical length scale that one has to observe, and then identify spatial regions with high probability for a rare event,” Sapsis said. “If you are performing operations on an aircraft carrier or offshore platform, this is extremely important.”

A Harvard psychologist says your success in any situation hinges on 3 things

Harvard psychologist Amy Cuddy is perhaps best known as the creator of the “power pose.”

As she described in her 2012 TED Talk, power-posing is about taking advantage of the body-mind connection: You adopt the body language of powerful people so that you feel and act more confident.

But power posing is just one path to a state of calm self-confidence that will help you succeed in challenging situations. That state, which Cuddy calls “presence,” is the subject of her new book by the same name.

Cuddy defines presence as being attuned to and able to express your full potential. When you’re present, you approach challenges without a sense of threat.

Whether you’re interviewing for a job or pitching your startup, people can tell right away if you’re present, and they judge you more positively when you are.

In an interview with Business Insider, Cuddy said there are three things people see when you’re present:

1. You believe your story

When you’re present, you demonstrate conviction and passion so that other people come to believe your story, too.

In the book, Cuddy describes a yet-unpublished study she conducted, in which participants went through mock interviews. For five minutes, they had to persuade the interviewer that they were the best person for the job, while being completely honest. All the while, the interviewer held a completely neutral expression.

Three independent pairs of judges watched videos of the interviews, looking for presence, believability, and hireability. Sure enough, the interviewees who were rated more present were also rated more believable and more hireable.

Cuddy writes: “Presence mattered to the judges because it signaled authenticity, believability, and genuineness; it told the judges that they could trust the person, that what they were observing was real.”

confident presentation public speakingJon Gosier/Flickr“A truly confident person does not require arrogance.”

2. You’re confident without being arrogant

In the book, Cuddy quotes a venture capitalist describing what turns him off during an entrepreneur’s pitch: “They’re too high energy and aggressive, maybe a little pushy. It seems defensive, I don’t expect them to have all the answers. Actually, I don’t want them to have all the answers.”

Being open to feedback is key, Cuddy told Business Insider. The more you shut down other people and their perspectives, the less appealing you become. That’s because it can seem like you’re trying to cover up a sense of uncertainty.

“A truly confident person does not require arrogance, which is nothing more than a smoke screen for insecurity,” Cuddy writes. “A confident person can be present to others, hear their perspectives, and integrate those views in ways that create value for everyone.”

3. Your verbal and nonverbal communication is in sync

When we’re being inauthentic — or when we’re intentionally deceiving someone — Cuddy said our verbal and nonverbal communication is incongruent.

In the book, she explains that’s because you’re constantly trying to adjust what you’re saying and doing to create the impression you think others want to see.

On the other hand, when we’re present, our verbal and nonverbal behavior matches. People aren’t distracted trying to figure out why something feels “off,” and they’re more likely to put their trust in you.

Ultimately, if you’re confident in yourself, other people will be more likely to be confident in you, too. It doesn’t necessarily mean you’ll get the job or the investor’s money, but you’ll walk away knowing that you did the best you could — and the right opportunity for you is out there.

Artificial control of exciplexes opens possibilities for new electronics

Artificial control of exciplexes opens possibilities for new electronics
This schematic shows the basic structure of an exciplex-based OLED with emission color and efficiency that can be controlled simply by changing the spacer thickness. An exciplex forms when a hole in the highest occupied molecular orbital …more
Demonstrating a strategy that could form the basis for a new class of electronic devices with uniquely tunable properties, researchers at Kyushu University were able to widely vary the emission color and efficiency of organic light-emitting diodes based on exciplexes simply by changing the distance between key molecules in the devices by a few nanometers.

This new way to control electrical properties by slightly changing the device thickness instead of the materials could lead to new kinds of organic electronic devices with switching behavior or light emission that reacts to external factors.
Organic electronic devices such as OLEDs and organic solar cells use thin films of organic molecules for the electrically active materials, making flexible and low-cost devices possible.
A key factor determining the properties of organic devices is the behavior of packets of electrical energy called excitons. An exciton consists of a negative electron attracted to a positive hole, which can be thought of as a missing electron.
In OLEDs, the energy in these excitons is released as light when the electron loses energy and fills the vacancy of the hole. Varying the exciton energy, for example, will change the emission color.
However, excitons are commonly localized on a single organic molecule and tightly bound with binding energies of about 0.5 eV. Thus, entirely new molecules must usually be designed and synthesized to obtain different properties from these Frenkel-type excitons, such as red, green, or blue emission for displays.
Researchers at Kyushu University’s Center for Organic Photonics and Electronics Research (OPERA) instead focused on a different type of exciton called an exciplex, which is formed by a hole and electron located on two different molecules instead of the same molecule.
By manipulating the molecular distance between the electron-donating molecule (donor) and the electron-accepting molecule (acceptor) that carry the exciplex’s hole and electron, respectively, the researchers could modify the properties of these weakly bound excitons.
“What we did is similar to placing sheets of paper between a magnet and a refrigerator,” said Associate Professor Hajime Nakanotani, lead author of the paper reporting these results published online February 26, 2016, in the journal Science Advances.
“By increasing the thickness of an extremely thin layer of organic molecules inserted as a spacer between the donor and acceptor, we could reduce the attraction between the hole and electron in the exciplex and thereby greatly influence the exciplex’s energy, lifetime, and emission color and efficiency.”
Indeed, the changes can be large: by inserting a spacer layer with a thickness of only 5 nm between a donor layer and an acceptor layer in an OLED, the emission color shifted from orange to yellowish green and the light emission efficiency increased 700%.
For this to work, the organic molecule used for the spacer layer must have an excitation energy higher than those of the donor and acceptor, but such materials are already widely available.
While the molecular distance is currently determined by the thickness of the vacuum-deposited spacer layer, the researchers are now looking into other ways to control the distance.
“This gives us a powerful way to greatly vary device properties without redesigning or changing any of the materials,” said Professor Chihaya Adachi, director of OPERA. “In the future, we envision new types of exciton-based devices that respond to external forces like pressure to control the distance and electrical behavior.”
In addition, the researchers found that the exciplexes were still formed when the spacer was 10 nm thick, which is long on a molecular scale.
“This is some of the first evidence that electrons and holes could still interact like this across such a long distance,” commented Professor Adachi, “so this structure may also be a useful tool for studying and understanding the physics of excitons to design better OLEDs and organic solar cells in the future.”
“From both scientific and applications standpoints, we are excited to see where this new path for exciton engineering takes us and hope to establish a new category of exciton-based electronics.”

‘MOTH EYE’ GRAPHENE BREAKTHROUGH COULD CREATE INDOOR SOLAR CELLS

A scientific breakthrough with the “wonder material” graphene has opened up the possibility of indoor solar cells that capture energy from indirect sunlight, as well as ambient energy from household devices.

Researchers from the University of Surrey in the U.K. studied the eyes of moths to create sheets of graphene that they claim is the most light-absorbent material ever created. The energy capture method could be used to power Internet of Things (IoT) devices, such as smart clothing, wearables and smart wallpaper.

“We realized that the moth’s eye works in a particular way that traps electromagnetic waves very efficiently,” Professor Ravi Silva, head of the Advanced Technology Institute at the University of Surrey, tells Newsweek . “As a result of our studies, we’ve been able to mimic the surface of a moth’s eye and create an amazingly thin, efficient, light-absorbent material made of graphene.”

“For many years people have been looking for graphene applications that will make it into mainstream use,” Silva says. “We are finally now getting to the point where these applications are going to happen. We think that with this work that is coming out, we can see an application very close because we’ve done something that was previously thought impossible: optimizing its incredible optical properties.

“Organic solar cells are based on polymers and these only really capture energy from the visible range. Now with the materials we have, it transcends all of that by being able to absorb over a much larger range. What we need to do is come up with a technology that allows you to use that efficiently, such as rectennas.”

Rectennas—or rectifying antennas—are a special type of antenna that can convert electromagnetic energy into direct current (DC) electricity. First conceived in 1964, Silva says rectennas are yet to realize their real-world potential.

Combined with Silva’s graphene breakthrough, rectennas would be able to efficiently capture and convert energy from ambient microwave and radio frequencies from household devices, such as smartphones, computers and lightbulbs. This scavenged energy could then be used to power smart sensors and IoT devices without the need for batteries or wired connectivity.

The research is published in Science Advances.
