Hearing is something that unfortunately always seems to go with age.

There is one animal however that doesn’t suffer these effects and its remarkable ability could hold the key to helping us prevent age-related hearing loss.

Barn owls are able to maintain their incredible sense of hearing even into old age.

Scientists at the University of Oldenburg, Gemrany, found that barn owls were able to actually regenerate cells and repair any damage to the inner ear.

Publishing their results in the journal Royal Society Publishings B, the team tested the hearing of seven captive barn owls, all varying in age.

Using a series of sounds covering the owl’s entire hearing range the team found that there was almost no difference in ability between young owls and the oldest that was 23-years-old.

The paper suggests that all birds somehow have a remarkable ability to avoid age-related hearing through inner ear regeneration.

If we can better understand how birds and in particular owls are able to do this we could eventually find a way to prevent it from happening in humans.

Sadly for our species, while we can heal wounds we can’t repair age-related damage to the inner ear.

According to the UK charity Action On Hearing Loss, the main cause of age-related hearing loss is damage to the cochlea known as presbycusis.

Presbycusis occurs when there is wear and tear to the tiny sensory cells within the cochlea known as hair cells.

Google Pixel 2 Leaks As Rival To The iPhone X And Galaxy S8

The Huffington Post UK - 7 hours 53 min ago
function onPlayerReadyVidible(e){'undefined'!=typeof HPTrack&&HPTrack.Vid.Vidible_track(e)}!function(e,i){if(e.vdb_Player){if('object'==typeof commercial_video){var a='',o='m.fwsitesection='+commercial_video.site_and_category;if(a+=o,commercial_video['package']){var c='&m.fwkeyvalues=sponsorship%3D'+commercial_video['package'];a+=c}e.setAttribute('vdb_params',a)}i(e.vdb_Player)}else{var t=arguments.callee;setTimeout(function(){t(e,i)},0)}}(document.getElementById('vidible_1'),onPlayerReadyVidible);

Apple aren’t the only tech giant to suffer from leaky smartphone launches.

Images claiming to show the brand-new Pixel 2 XL have leaked just weeks before Google is expected to unveil the flagship smartphones at a major event on the 4 October.

The images, obtained by DroidLife, show a phone with a much larger camera but a similar design language to that of the original Pixel.

Reportedly made by LG, the Pixel 2 XL is expected to come with a bezel-less display that looks very similar to the displays found on both LGs own flagship phones.

Another website Android Police were able to obtain a similar image of the Pixel XL which better shows the phone’s OLED display.

According to DroidLife, the Pixel will be available in just Black and White and will come with two storage sizes: 64GB and 128GB.

Unfortunately that’s just about all we know about Google’s rival to the Galaxy S8 and the iPhone X.

In addition to both phones leaking, it looks as though Google will also be announcing a smaller version of their Google Home smart speaker designed presumably, to compete with Amazon’s Echo Dot.

Porsche Mission E Is A Rival To The Tesla Model S And It Looks Incredible

The Huffington Post UK - 19 September 2017 - 5:34pm
function onPlayerReadyVidible(e){'undefined'!=typeof HPTrack&&HPTrack.Vid.Vidible_track(e)}!function(e,i){if(e.vdb_Player){if('object'==typeof commercial_video){var a='',o='m.fwsitesection='+commercial_video.site_and_category;if(a+=o,commercial_video['package']){var c='&m.fwkeyvalues=sponsorship%3D'+commercial_video['package'];a+=c}e.setAttribute('vdb_params',a)}i(e.vdb_Player)}else{var t=arguments.callee;setTimeout(function(){t(e,i)},0)}}(document.getElementById('vidible_1'),onPlayerReadyVidible);

Porsche’s incredible Mission E all-electric concept car pretty much took everyone by surprise when it was first unveiled in 2015.

Thanks to its futuristic styling it seemed unlikely that the car would ever become more than simply a reference point for far more sensible-looking electric cars in the future.

Well think again, because the Mission E is in fact a real car, and it’s being released in 2019.

According to Car Magazine, Porsche greenlit the car and will actually start road testing it next year.

It’s a huge project too, requiring around €700m of investment and a brand-new manufacturing facility where the car’s electric batteries and motor will be produced.

 

The magazine goes on to confirm that the Mission E will feature the same specs as the concept car including a 0-60mph time of less than 3.5 seconds and a range of around 300 miles.

What’s really impressive however is how quickly it will be able to charge itself.

According to Porsche it will feature a new fast-charging technology that will allow the Mission E to charge to 250 miles in just 15minutes.

Finally, and perhaps most importantly, the company has confirmed that the finished car will look very similar to the stunning concept that was first unveiled back in 2015.

So how much will one of these cost? Well Porsche says it will have the same price as its entry-level saloon the Panamera.

That’ll mean it should have a UK price of around £67,000-70,000 placing it right alongside Tesla’s Model S.

Porsche’s parent company Volkswagen recently announced that it would make electric versions of every car within its range by 2030.

The landmark decision will see the world’s largest carmaker develop some 300 electric or hybrid models across 12 manufacturers.

UK Facility To Engineer One Billion 'Safe' Mosquitos A Week In Fight Against Diseases

The Huffington Post UK - 19 September 2017 - 5:14pm
function onPlayerReadyVidible(e){'undefined'!=typeof HPTrack&&HPTrack.Vid.Vidible_track(e)}!function(e,i){if(e.vdb_Player){if('object'==typeof commercial_video){var a='',o='m.fwsitesection='+commercial_video.site_and_category;if(a+=o,commercial_video['package']){var c='&m.fwkeyvalues=sponsorship%3D'+commercial_video['package'];a+=c}e.setAttribute('vdb_params',a)}i(e.vdb_Player)}else{var t=arguments.callee;setTimeout(function(){t(e,i)},0)}}(document.getElementById('vidible_1'),onPlayerReadyVidible);

A UK-based biotech company is stepping up its fight against viruses like Zika by building a huge facility that can engineer one billion ‘safe’ mosquitos every single week.

Known as the Friendly Aedes mosquito, these males do not bite or transmit diseases. When they mate with a female the offspring inherit a self-limiting gene that causes them to die before reaching functional adulthood.

By introducing vast numbers of these engineered mosquitos governments can start to effectively combat wild populations that can spread deadly diseases such as Zika, yellow fever and dengue.

Run by Oxitec Ltd, a subsidiary of Intrexon Corporation, the UK facility was unveiled by both Intrexon’s CEO and Prime Minister Theresa May at a roundtable event in New York City.

The new £7.3m facility will increase Oxitec’s production of the ‘safe’ mosquito eggs by more than 20-fold and has been designed to meet increasing demand.

Oxitec believe its approach to mosquito population control is unique thanks to two key features.

type=type=RelatedArticlesblockTitle=Related... + articlesList=596ca874e4b03389bb18ba67,57188cbbe4b0f9085c2cdb87,59afad4ee4b0dfaafcf3aeb8

The first is that every one of their mosquitos passes on a flourescent market that allows for precise tracking. Secondly, all Friendly Aedes mosquitos die along with their offspring, effectively preventing them from persisting in the environment and removing any ecological footprint.

Oxitec certainly aren’t the only company to been investing in this form of mosquito control.

Earlier this year Google’s sister company Verily Life Sciences revealed an ambitious plan to unleash 20 million infected mosquito’s into the heart of California.

In this instance the mosquitos are infected with a bacteria called Wolbachia. This makes the mosquito sterile, so when they go out and mate with the biting females, the results are eggs that never hatch.

Eventually Verily believe they can reduce local populations by a significant amount, but without any genetic modification at all.

Scientists Find That If You 'Trust Your Gut' You're More Likely To Believe Fake News

The Huffington Post UK - 19 September 2017 - 2:41pm
function onPlayerReadyVidible(e){'undefined'!=typeof HPTrack&&HPTrack.Vid.Vidible_track(e)}!function(e,i){if(e.vdb_Player){if('object'==typeof commercial_video){var a='',o='m.fwsitesection='+commercial_video.site_and_category;if(a+=o,commercial_video['package']){var c='&m.fwkeyvalues=sponsorship%3D'+commercial_video['package'];a+=c}e.setAttribute('vdb_params',a)}i(e.vdb_Player)}else{var t=arguments.callee;setTimeout(function(){t(e,i)},0)}}(document.getElementById('vidible_1'),onPlayerReadyVidible);

Researchers from Ohio State University have found that people who tend to rely on their ‘gut feelings’ are more likely to believe fake news.

The study, which involved three surveys, looked at how people form their beliefs and what factors help guide those decisions whether it’s hard evidence, previously political bias or simply just going with instinct.

Each participant was asked 12 questions including “I trust my gut to tell me what’s true and what’s not,” “Evidence is more important than whether something feels true” and “Facts are dictated by those in power.”

Analysing the responses to these questions the team then assessed how much each person relied on their intuition or ‘gut instinct’, how much they valued hard evidence and whether or not their believed that the ‘truth’ was political.

Kelly Garrett, lead researcher and a professor of communication at The Ohio State University, explains:

“A lot of attention is paid to our political motivations, and while political bias is a reality, we shouldn’t lose track of the fact that people have other kinds of biases too.”

The team did indeed find that other biases did play an important role in how people cemented their beliefs.

To gauge how people were coming to these decisions they used a number of controversial topics including the link between vaccines and autism and the old favourite of whether or not climate change is the fault of humanity.

The team then expanded this to well-known conspiracy theories. They found that more than 45% don’t buy that Kennedy was killed by Lee Harvey Oswald while 33% believe Martin Luther King was assassinated by the U.S. government.

Ultimately Garrett found that overall the results were as you would expect: People who believe the truth is political were much more likely to believe falsehoods. Whereas those who rely on hard evidence for their beliefs are less likely to fall foul of fake news.

What was really interesting though was a third connection they found which was that those who rely on intuition in order to learn the truth are more likely to endorse conspiracies or falsehoods.

type=type=RelatedArticlesblockTitle=Related... + articlesList=5938002ae4b0aba888ba6986,58ee4597e4b0f3927474802e,58f5b05de4b0da2ff862c1ce

“While trusting your gut may be beneficial in some situations, it turns out that putting faith in intuition over evidence leaves us susceptible to misinformation,” said Brian Weeks, who worked on the research as an Ohio State graduate student.

This is important because it shows that people’s decisions about whether something is true is not based solely on their political views or political bias.

“Misperceptions don’t always arise because people are blinded by what their party or favourite news outlet is telling them,” says Garrett.

The solution? “People sometimes say that it’s too hard to know what’s true anymore. That’s just not true. These results suggest that if you pay attention to evidence you’re less likely to hold beliefs that aren’t correct,”

When Is iOS 11 Out? UK Release Time And Tips On How To Download

The Huffington Post UK - 19 September 2017 - 12:36pm
function onPlayerReadyVidible(e){'undefined'!=typeof HPTrack&&HPTrack.Vid.Vidible_track(e)}!function(e,i){if(e.vdb_Player){if('object'==typeof commercial_video){var a='',o='m.fwsitesection='+commercial_video.site_and_category;if(a+=o,commercial_video['package']){var c='&m.fwkeyvalues=sponsorship%3D'+commercial_video['package'];a+=c}e.setAttribute('vdb_params',a)}i(e.vdb_Player)}else{var t=arguments.callee;setTimeout(function(){t(e,i)},0)}}(document.getElementById('vidible_1'),onPlayerReadyVidible);

Apple has released iOS 11, its latest version of its mobile operating system for iPhone, iPad and iPod Touch.

The release, scheduled ahead of the iPhone 8 and iPhone X release dates, is one of Apple’s biggest updates yet with some powerful new features and a complete redesign of some of the iPhone’s most-used features.

Where iOS 11 will really make an impact however is with the iPad, giving it more Mac-like features including the ability to manage your files using folders, a Mac-style dock at the bottom and seamless multi-tasking.

When is iOS 11 out?

iOS 11′s UK release date is the 19 September. Now contrary to what you might think the update does not go live in the morning, so don’t panic if you haven’t seen that little notification pop up yet.

Instead iOS 11 will go live in the UK from 6PM GMT.

How to download iOS 11

Downloading iOS 11 is a relatively straightforward process but it does require you do to a bit of housecleaning before you can press that ‘Download and Install’ button.

1. Backup your iPhone/iPad to iCloud.

Apple’s software updates are almost always smooth hiccup-free experiences, however in the off-chance that something does go wrong and your iPhone didn’t backup the night before then you’re going to be in trouble.

This is really easy to avoid. Simply plug in your iPhone or iPad to a charging outlet, connect to a WiFi network and then go to: Settings - Tap on your name at the top - iCloud - iCloud Backup - Back Up Now.

You’ll then see a small bar indicating that your device is backing up.

2. Make sure you have enough storage.

One of the most common issues is that people will press ‘Download and Install’ but then get an error message informing them that they don’t have enough storage.

This is annoying but again there are some simple things you can do to prevent it happening and in the long run it’ll let you take more photos, videos and store more songs on your device.

Check out our article for easy tips on how to free up storage: 

3. Download and install iOS 11

Now you’re backed up and you have enough space you’re ready to go.

Your iPhone or iPad will be out of action for a while and make sure it either has over 50% of battery or is charging while you’re doing it.

Anytime past 6PM GMT on the 19 September simply head to: Settings - General - Software Update - Download and Install.

What’s new in iOS 11

To check out a complete list of all the new features coming to iOS 11 on iPhone and iPad head here.

Here are some highlights though:

Messages is a lot better

Apple’s Messages app has been given a subtle but important update. Before you bring up the keyboard, conversations will now allow you to quickly access your iMessage apps.

Your iMessage conversations are now also synched across all your Apple devices automatically which means everything from conversations to individual messages can now be synched and deleted across all devices.

You can take a LOT more pictures

The camera gets a small update but one that’s going to make a huge difference to your storage woes.

Apple’s moving over from JPEGs to a new type of image formate called HEV. It’s still compatible with everything you use currently but thanks to compression technology that’s twice as good it now massively reduces the amount space it’s going to take up on your phone.

Control Centre has been completely redesigned

Control Centre now has a new minimalist look that takes up just one screen so there’s no swiping between different cards. It looks more simplistic but Apple’s using 3D Touch on the newer iPhones to let you expand them into more complex settings menus.

Apple Music is more social 

Apple Music hasn’t been given the major overhaul it was given last year. This time it’s about bringing your friends into the mix. You now have a profile that can be set as public or private.

Your friends’ Apple Music listening habits will then appear on your app and help you find new music or allow you to tap into their playlists and music tastes.

The iPad is now more like a computer

iOS 11 has the potential to fundamentally change how we use the iPad thanks to some major new features.

First up is Files, a new iOS app that lets you see every photo, video and document stored both on your device and in the cloud in a way that will feel very familiar to anyone who uses a MacBook or iMac.

Secondly there’s the new Dock, which is a permanent tray of apps that you can swipe up and access at any given point, again very similar to macOS. To open multiple apps you simply press and hold on the dock and drag that app up into the screen.
