Jetjacky:
How can kissing be related to science and technology Abi you high?? Educating us about kissing doesn't go to science and technology... It goes to health. Stop given me a headache

If you don't see how this belongs in science and technology then you're the one that must be high and you obviously didn't read the article, which makes your argument invalid.

Jetjacky:
More like education or romance...

Please tell me that's a joke.

Jetjacky:
Guy this is not the room for that

Where does this belong then?

It’s been tenuously suggested that kissing puts people at a greater risk of getting oral cancer than smoking, with more people developing the disease due to the human papillomavirus (HPV) than those who smoke.

HPV is a common infection that is spread through skin-to-skin contact and is normally harmless. It can survive in the genitals and mouth of both men and women, and is the leading cause of cervical cancer. So does HPV really put you at a greater risk for mouth cancer than smoking?

Around eight out of 10 people will be infected with HPV at some point in their life, but that is no reason to panic. There are hundreds of different types of HPV, most of which are harmless, with only around 15 implicated in causing cancer. These are known as “high-risk” HPV types. The vast majority of the time, our immune system can deal with the virus and overcome it, but occasionally people with persistent infections of high-risk types might go on to develop cancer.

The virus causes the cancer to develop indirectly. HPV infections start in the deepest layers of the skin, causing the cells to rapidly divide so that it can make more viruses. Sometimes, in high-risk cases, the virus will damage the cells’ DNA, meaning the cells start to grow out of control and lead to cancer.
The main risk factors for developing mouth cancer are thought to be drinking alcohol and smoking, but a growing body of evidence suggests HPV might also be a significant cause. According to the NHS, around 25% of mouth and 35% of throat cancers are HPV-related, though the numbers vary. Cancer Research UK report that more than 40% of oral cancers are linked to HPV infection, a figure that is growing.

So will kissing give you cancer? Well, the CDC states that around 7% of people in the U.S. have oral HPV, and of those, around 1% have the specific high-risk type that can lead to cancer. Most cases of the infection are likely through MouthAction, with straight men in their 40s and 50s the most likely to be infected. This implies that MouthAction on a woman is riskier than MouthAction on a man, which is thought to be linked to how much of the virus is shed by the vulva and penis, respectively.

So while HPV-related oral cancer might be on the rise, it is still incredibly rare, and it's probably not worth worrying about whether or not the next person you kiss will increase your risk.

Teempakguy:
you're right. They're not competing. In fact, this technology might be later used to power augmented reality devices.

I'm agreeing with you on this one. the technology seems to have potential, now that I think of it, so, we will have to wait and watch.

Meanwhile, holographic displays now have a new meaning . . . apparently. Much different from what you think they are . . .

Ok let me correct you one more time, it may power virtual reality devices not Augmented reality.

And yes holographic displays now seem to mean something different to what everyone thought they would be in the past.

Limbo is the only game I've played on this list, twice once on my pc then again on my tablet. I love that game.

IamforGod:
This is what u get when a 24 yrs old kid is the mentor of a 32 yrs old full grown wannabe musician smh!

hahahahahah you don kill person.

Teempakguy:
kindly google search microsof hololens Demo

after that, go on to google magic leap.
Then tell me what you think.

You're talking about Augmented reality? seriously man 1st those are not hologram displays,
2nd these two technologies have different applications, they're not competing with each other, it's like saying the oculus rift is going to replace pc monitors.

Teempakguy:
holograms.
Computers that project screens into the real world. These screens can be resized, bent, and manipulated in anyway because they are virtual constructs.
Who needs a flexible screen when you can have five or more, following you around anywhere you go? And that you can resize at will?

So, one can only hope that we find this technology attractive enough to choose it.

Holographic displays are still a concept, when they become a reality then maybe they'll outpace current display technology, like flexible displays which exist now.

Teempakguy:
Nice technology.
Unfortunately, it may not be successful.

What do you mean?

The position in which you sleep might be have an impact on more than your just your posture; it could also impact your mental health. New research suggests that it might be related to how the brain removes waste chemicals, and that some positions might be better for this than others.

The researchers found that sleeping on one’s side, compared to sleeping on one’s back or stomach, appeared to allow the body to more efficiently clear waste chemicals from the brain. “It is interesting that the lateral [side] sleep position is already the most popular in humans and most animals – even in the wild – and it appears that we have adapted the lateral sleep position to most efficiently clear our brain of the metabolic waste products that build up while we are awake,” explained Maiken Nedergaard from the University of Rochester in New York, who was involved with the study.

The scientists used "dynamic contrast" magnetic resonance imaging (MRI), which uses a special chemical to improve visability of internal structures, to image what’s called the brain’s “ glymphatic pathway.” This is the system whereby cerebrospinal fluid (CSF), the clear liquid found in the brain, filters through the brain and exchanges with interstitial fluid (ISF), the liquid found around all other cells in the body. This allows chemicals and waste that build up in the brain to be removed, such as amyloid beta and tau proteins, which are associated with Alzheimer’s and Parkinson’s.

It’s been known that this process happens more when we’re sleeping, with clinical studies showing that sleep drives the removal of amyloid beta from the brain, but this study shows that apparently the position in which we sleep might also influence this clearance. The team anesthetized rats, and then tracked the efficiency of the glymphatic pathway when the rodents were sleeping in one of three positions, either lateral (on their side), prone (on their bellies), or supine (on their backs).

“The analysis showed us consistently that glymphatic transport was most efficient in the lateral position when compared to the supine or prone positions,” explained Dr. Helene Benveniste, who coauthored the study published in the Journal of Neuroscience. “Because of this finding, we propose that the body posture and sleep quality should be considered when standardizing future diagnostic imaging procedures to assess CSF-ISF transport in humans.”

It’s interesting in that many mammals naturally tend to sleep on their sides, from dogs to cats and even elephants, although the authors do note that a wild animal's sleeping behavior is also probably influenced by survival, and thus might be different when compared to humans. As this study was done on rats, it’s not yet known whether the same conclusions can be drawn for humans, but considering it’s been shown that both the rodents and people tend to favor sleeping on their side, it’s not such a wild idea.

“Many types of dementia are linked to sleep disturbances, including difficulties in falling asleep,”
concludes Nedergaard. “It is increasingly acknowledged that these sleep disturbances may accelerate memory loss in Alzheimer’s disease. Our finding brings new insight into this topic by showing it is also important what position you sleep in.”

Newest flexible technology. LG Display

LG Display continues to be the leading pioneer in flexible technology - debuting its new flexible TV panel at an event in Korea this week.
18 inches wide, the screen offers high definition viewing and 1 million megapixels – but can be rolled up into a 3 cm radius without damage to the screen or technology.

The screen was made possible by its OLED , or organic light emitting diode, technology, which allows it to be lighter, thinner and more flexible than standard LCD screens.

At an event in Korea earlier this week, LG demonstrated its newest flexible display screens, which are 55 inches wide and paper-thin at 0.97 mm thick, and weigh just 1.9 kg – all the while still offering high definition. Attachable to surfaces via magnets, the new screen can be fitted to curved walls.

The benefits of this technology are that eventually, bendable TVs, tablets and smartphones will be much easier to transport and a lot less likely to sustain damage. Other companies such as Apple and Samsung have also been developing the technology – but although Apple offered up its most malleable iPhone yet in the form of the 6th generation smartphone, and Samsung previously promised flexible smartphones in 2015, neither have released any devices with the new fully-flexible technology.

LG Display uploaded a video to YouTube showing the screen in action.

A cutaway view of the proposed ARC reactor. MIT ARC team.


Ah, fusion power. Holy grail of our energy problems. The savior of life on Earth. Our key to the stars. Source of power for Tony Stark's Iron Man .

But the only problem is that people have been saying this for many, many years (except the Iron Man bit). Fusion power always seems like it’s just on the horizon before, a few years later, we seem to be back to square one again.
Now a team from the Massachusetts Institute of Technology (MIT) thinks we might finally have a reason to get excited, although we should still err on the side of cautious optimism. Using a new type of superconductor, they say they can reduce the size of a potential fusion reactor while drastically increasing its power output. “It changes the whole thing,” Dennis Whyte, a professor of Nuclear Science and Engineering and director of MIT’s Plasma Science and Fusion Center, said in a statement .
Quite.

Their proposal involves a type of reactor known as a tokamak , which is donut-shaped. A fusion reactor recreates the Sun’s process of fusing hydrogen atoms together to form helium at its core, which releases enormous amounts of energy. One of the hardest parts of replicating this, though, is heating the plasma required for the reaction to temperatures equivalent to the core of a star, about 15 million degrees Celsius (27 million degrees Fahrenheit), while keeping it confined.

Doing so has relied on using magnetic fields produced by copper conductors to trap the heat and particles in the center of a reactor, but producing strong enough magnetic fields via this method is a complicated, not to mention bulky, process.

So, what if there was another way?

In their paper in Fusion Engineering and Design , the MIT team explain that by using rare-earth barium copper oxide (REBCO) superconducting tapes instead of copper, high-magnetic field coils can be created at a fraction of the size. In fact, they say they could actually increase the fusion power by a factor of 10 in their experimental reactor, nicknamed ARC (hat tip to Iron Man), when it is cooled to the temperature of liquid nitrogen, about -200°C (-330°F). This is because the new superconductors produce a stronger field than their copper counterparts.

“The much higher magnetic field allows you to achieve much higher performance,” said Ph.D. candidate Brandon Sorbom from MIT in a statement .

These new superconductors also do not overheat quickly, unlike copper, so they can theoretically produce a steady power output. The team said the reactor could produce up to six times as much energy as is needed to actually keep it running, enough for 100,000 people. No fusion reactor has ever been demonstrated to produce as much or more energy as it uses.

“Fusion energy is certain to be the most important source of electricity on Earth in the 22nd century, but we need it much sooner than that to avoid catastrophic global warming,” said David Kingham, CEO of Tokamak Energy Ltd. in the U.K., who was not connected with this research, in the statement . “This paper shows a good way to make quicker progress."

The ARC reactor is simply a proposal for now, but the team said it could potentially be built in just five years. For comparison, construction on a huge $40 billion (£26 billion) experimental fusion reactor in France called the International Thermonuclear Experimental Reactor (ITER) began in 2013, and is expected to be completed in 2019. It was designed before these new superconductors were available.

Whether this research proves to be the real deal, or proves no more real than the contraption worn by Tony Stark, remains to be seen. So, let’s all nervously raise a glass to what may or may not be a breakthrough in what may or may not be the answer to our energy woes.

How do I get it in Asaba?

Life after GEJ has indeed become an economic hell for Raymond Dokpesi and his Daar Group. It has now become obvious that AIT has been secretly funded by the past administration hence the recent bankruptcy and inability to pay staff.

Really? I wonder how dey were getting their funding before GEJ's administration.
yeye dey worry you

U are right but wrong when you said retract message feature is subscription based. Its not. Its a permanent feature in all updated BBM.

It is subscription based, along with timed messages and the rest. When you have used it for awhile you'll start getting this message. ↓

intrepid:
Meaning that one is stuck right? No delete message feature is available on bbm?

Right.

1st End Chat doesn't delete the contact or messages, and only way to delete specific messages on bbm is to update your bbm to the latest version and use the retract message feature but that feature is subscription based and you are only able to use it for a trial period and its also dependent on whether the person you're trying to retract their message has the updated version of bbm.

nawa o, another one? this is getting too much o, what is wrong with Nigerian men nowadays na

What do you mean by nowadays?

They got fired for criticising the government?!
I thought freedom of speech was part of our Constitution?
This is a human rights violation and the sacked officials shouldn't take it lying down.

I'm interested, how I get it in Asaba?

I noticed it too, it's good.

If only..... As much as I like Nairaland I've been slowly getting sick of it's continuous BS.

These days i prefer to skip the front-page and just view my boards of interest, because one glance at the garbage on front-page makes me sad.

Nairaland seriously needs to fix their anti-spam bot, that shît's overzealous.

Tufia! Nairaland has become trash, of all the informative and Educational posts on Nairaland this garbage is what is put on front-page. una sorry.

Pineapples are thought to have originated in South America and were first discovered by Europeans in 1492 on the island of Guadeloupe. However, pineapples didn't make it to England until the late 1600's, where it quickly became a must-have item for the wealthy. Worth around $8,000 (£5000) each, only the absolute elite could afford this exotic fruit, and according to one [url=blogs.unimelb.edu.au/sciencecommunication/2012/10/07/the-flesh-eating-pineapple/]source[/url] , the fruit wasn't even eaten – just carried around under one's arm at parties and social events as a status symbol.

If you've ever eaten a pineapple, you'll have experienced that weird, scratchy, rough feeling on your tongue after you've munched through a few chunks. So why does that happen?

It turns out that pineapple contains bromelain , a mixture of enzymes that digest proteins. Despite bromelain being an approved anti-inflammatory treatment and having other health benefits, when it comes into contact with the sensitive skin in and around one's mouth, it's actually breaking down proteins, causing the tissue to become sore and inflamed.

So your favorite fruit is essentially eating your mouth. Yes, we're being dramatic. But you get the point.
