Hearing Loss Increases Risk of Dementia, Depression | Your Lupus ...

Because of the gradual nature of the condition, it?s quite possible for someone to have hearing loss and not know it. In fact, it?s usually friends and family members who have to bring it to the affected individual?s attention. High television and radio volumes, trouble with phone calls, and missing portions of conversations are major warning signs. If you or someone you know is suffering from hearing loss, you should seek the aid of Los Angeles hearing specialists.

There are many factors that contribute to hearing loss, such as trauma, infections, heredity, and ear wax build-up. Noise exposure is the number one cause of hearing loss. This can come from sudden, loud noises or prolonged exposure.

Hearing loss is usually classified into two categories: conductive and sensorineural. Problems with the middle and outer ear are associated with conductive hearing loss. The auditory nerve functions normally, but blockage prevents sound from reaching the inner ear. Sensorineural hearing loss is the result of damage to the auditory nerve or auditory hair cells. Mixed hearing loss is a combination of the two.

Aside from the immediate effects of hearing loss, the condition puts you at risk for other health problems like diabetes, kidney disease, and dementia. Also, since hearing is linked with balance, hearing loss increases your risk of suffering from falls.

When treating hearing loss, hearing aids are the most common and effective remedy. There are a lot of preconceived notions about hearing aids, which cause people to think that they won?t work for them . Early hearing aid technology had its issues: feedback, constant adjustment, and inadequate amplification just to name a few. Advances in digital technology have fixed these problems. Digital noise reduction detects bothersome background noise and filters it out. Digital feedback reduction does much the same by preventing sound, such as those produced by the hearing aid, from being re-amplified, which results in feedback.

To get a hearing aid, it is suggested that you go to either a hearing aid dispenser or an audiologist. A hearing aid dispenser is licensed to prescribe hearing aids, but their training is less comprehensive. An audiologist, on the other hand, has more experience and training and a better overall understanding of how the ear functions. As with most health conditions, the more experience the better. So, if you have trouble hearing, it is best to seek the help of an audiologist .

No matter the severity of hearing loss, it is a safe bet to get your hearing tested. Your hearing affects more than you may think. If you have trouble hearing, your conversations with friends and family will suffer, resulting in damaged relationships. Your hearing could also cost you a great business opportunity or, worse yet, your career. Hearing also plays a significant role in day-to-day safety; the honk of a car horn or a smoke alarm could save your life.

Hearing loss is nothing to be ashamed of. Hearing degrades naturally over time, so each and every one of us will have to accept the fact that our hearing?s not what it used to be, at least at some point in our lives. Why wait any longer? Seek the help of a Los Angeles hearing specialist or audiologist today.

Official: US troop opened fire on Afghan civilians

KABUL, Afghanistan (AP) ? A U.S. service member walked out of his base in southern Afghanistan before dawn Sunday and started shooting Afghan civilians, Afghan and NATO officials said. There were widely varying reports of casualties.

People were killed in the shooting spree in Kandahar province, Gov. Tooryalai Wesa said, though he did not provide numbers.

"The incident happened. There are some people killed, some wounded. But I don't have the details," Wesa said in a phone interview.

Helicopters were circling overhead at Alkozai village in Panjwai district as a delegation from the governor's office arrived to determine exactly what happened, but details were still sketchy.

A resident of Alkozai, where the shootings took place, told an Associated Press reporter that 16 people were killed as the U.S. service member went into three different houses and started shooting. The villager, Abdul Baqi, said he had not seen the bodies himself, but had talked to the family members of the dead.

"When it was happening in the middle of the night we were inside our houses. I heard gunshots and then silence and then gunshots again," Baqi said.

NATO spokesman Justin Brockhoff said a U.S. service member had been detained as the alleged shooter and that the coalition had reports of "multiple wounded" but none killed. The wounded were evacuated to NATO medical facilities, he said.

The service member was being held at a NATO base and U.S. forces are investigating the shooting in cooperation with Afghan authorities, Brockhoff said. He said it was not clear if the alleged shooter knew the victims.

"This is a deeply regrettable incident and we extend our thoughts and concerns to the families involved," NATO said in a statement.

There were reports of protests in Panjwai following the shooting and the U.S. embassy warned travelers in Kandahar province to "exercise caution."

The shooting comes after weeks of tense relations between U.S. forces and their Afghan hosts following the burning of Qurans and other religious materials at an American base. Though U.S. officials apologized and said the burning was an accident, the incident sparked violent protests and attacks that killed some 30 people. Six U.S. troops have been killed in attacks by their Afghan colleagues since the Quran burnings came to light.

In the capital, meanwhile, Afghan President Hamid Karzai said the government still expects to sign a strategic partnership agreement with the United States by the time a NATO summit convenes in Chicago in May. The agreement would formalize the U.S.-Afghan relationship and the role of U.S. forces in Afghanistan after NATO's scheduled transfer of security responsibility to the Afghan government at the end of 2014.

But Karzai stressed the importance of foreign forces leaving Afghanistan to preserve the country's national sovereignty. Any international forces that remain after 2014 would have to operate under strict guidelines governing their responsibilities and when they could leave their bases, he said.

"We have a strong army and police, so it is to our benefit to have good relations with the international community, not have international troops in our country," Karzai said at a public event in Kabul.

The president has demanded that international forces stop night raids on the homes of suspected militants as a condition to signing the strategic partnership agreement. The raids have caused widespread anger among Afghans.

Also Sunday, a prominent Afghan women's rights activist said gunmen attacked her office in a western province in an apparent assassination attempt.

Malalai Joya, a former Afghan lawmaker and vocal critic of both the Taliban and of criminality in the Afghan government, said the attack on her office in Farah province was the sixth attempt on her life to date.

Armed men tried to storm the compound before dawn on Saturday, she said. The attackers did not get into the building but two of her guards were seriously injured and are currently in the hospital.

Joya said she was in Kabul at the time but had planned a trip to Farah soon and news of that may have leaked out. She said she believes the attackers thought she was in the building.

The Cascade Inn ? Does Your Mother Know?

Do your parents know where you are at night? According to 36 per cent of 15 year old boys and nearly a quarter of 15 year old girls the answer to that question, at least once a month, is no.

This is the finding from Understanding Society, a long term study of 40,000 UK households, which asked more than 2,000 10-15 year olds how frequently they stayed out past 9.00pm without their parents knowing where they were. The study, which is funded by the Economic and Social Research Council (ESRC), also found that staying out late without telling your parents is unrelated to factors such as family income, the number of children in the family or being in a step-family, but is related to the quality of the emotional relationship the child has with their parents and whether they live in a city or in the country.

Staying out late in adolescence is an accepted sign of growing independence, but this study finds that there is a small minority of 15 year olds ? seven per cent of boys and five per cent of girls ? who regularly stay out late without their parents knowing where they are. It is within this group that the association with problem behaviours such as smoking and drinking is found. Regularly staying out late is linked with visiting pubs or bars more often; with frequency of alcohol consumption; with smoking, and with cannabis use. These associations are visible for both boys and girls, though they are more pronounced for girls in relation to smoking and drinking.

* 64 per cent of 15 year old girls who stay out frequently past 9.00pm without their parent?s knowledge consumed alcohol more than once in the last month, compared with only 25 per cent of girls who hadn?t stayed out in the past month;

* 18 per cent of 15 year old girls who have not stayed out past 9pm smoke. This rises to 51 per cent among girls who stay out frequently

* Five times more boys who frequently stay out late without their parents knowing where they are report ever having used cannabis, compared to boys who do not stay out late

Dr Maria Iacovou from the Institute for Social and Economic Research at the University of Essex, who analysed the data, says: Staying out late does not cause young people to smoke and drink, but regularly staying out late without telling their parents where they are is symptomatic of a young person with underlying problems. This is revealed by the fact that 19 per cent of boys regularly staying out late have behaviour problems and 26 per cent of girls in this group score highly for hyperactivity. We also see a third of young women in this group with self-esteem problems.

When the researchers looked at the home life of the young people they found that being in a step family, the number of family members living at home or family income does not increase the likelihood of them regularly staying out past 9.00pm without telling their parents where they are. What is important are family relationships, with children who hardly ever talk about important matters with their mothers and often quarrel with them more likely to stay out late.

Living in social housing or with a single mother also increases the probability of young people staying out without informing their parents of their whereabouts. There are differences by nationality and ethnicity: there are no meaningful differences between white and African/Caribbean youngsters, but Scottish teenagers are more likely, and those from Asian backgrounds are less likely, to stay out late.

There are also differences by the size of the community in which young people live: those living in hamlets and villages are less likely than those in towns and cities to go out at night without their parents knowing where they are. Young people who travel to school by independent means (on foot, bicycle, bus or train) are more likely than those who are taken to school by car to stay out at night.

Dr Iacovou added: This study shows that that the factors associated with staying out late without your parents knowing where you are, are complex and cannot simply be attributed to bad parenting. Geographical location plays a part too and may relate to local entertainment opportunities. Other factors such as the mode of travel to school probably relate to independence on the part of young people and trust on the part of their parents; while others, most notably family relationships, demonstrate that social and emotional deprivation also plays a role.

Seagate GoFlex Turbo (750GB)


The Seagate GoFlex Turbo (750GB) ($169.99 list) is a compact laptop-class drive in Seagate's GoFlex portable hard drive family. Like the Seagate GoFlex Slim ($99.99 list, 4 stars), the Turbo contains a speedy 7,200rpm drive mechanism. Unlike the 320GB Slim, the Turbo comes in 500GB and 750GB (tested) capacities plus it fits Seagate's other GoFlex adapters better, so it's ultimately more useful. If you have Thunderbolt or USB 3.0 on your Mac or PC, get this drive. We've made it our new Editor's Choice for notebook-class external hard drives. It's the one you've been waiting for.

Design and Features
The GoFlex Turbo is a compact hard drive, measuring about 0.5 by 3.5 by 4.5 inches (HWD). It has the same glossy black plastic top panel and matte bottom panel styling as other GoFlex drives, but the wrap-around sides have a faux-aluminum look with a prominent "Turbo" logo on the front. The logo is kind of obvious sports car-style branding, but otherwise the look is professional. The GoFlex Turbo has the usual SATA-style GoFlex connector on the back, and comes with a combo USB2.0/3.0 adapter. Seagate has a plethora of optional adapters including FireWire 800 and eSATA, but the hot adapter for this drive is the speedy Seagate GoFlex Thunderbolt Adapter ($99 list, 4 stars). The Thunderbolt adapter will let you eke every bit of throughput out of this speedy drive, though USB 3.0 isn't too shabby either. The combo of the GoFlex Turbo plus the Thunderbolt adapter will be a lot less expensive ($269.98) than the LaCie Little Big Disk Thunderbolt (240GB SSD) ($899.99 list, 4 stars).

The drive comes with a few utilities packed in, including backup and encryption utilities. Of course, you can simply use the backup utilities built into Windows 7 or Mac OS X. The drive comes formatted for NTFS (native Windows format), but the GoFlex Turbo can be easily reformatted. The drive comes with two years of SafetyNet data recovery services. This means that for those two years, you can rest assured that even if the drive fails, Seagate will attempt to recover the data from it for you. The first level of recovery is used if you can still access the drive: Seagate will try to recover the data remotely over the Internet. If that doesn't work, you'll be asked to send the drive for in-lab recovery. Like the ioSafe Rugged Portable SSD (120GB) ($499 list, 4.5 stars), you get one attempt during the subscription time period. Unlike the ioSafe, Seagate doesn't automatically send you a replacement drive while they're working on the in-lab recovery: you have to go through Seagate warranty claims if you still have a valid warranty. Also, while ioSafe provides shipping for free, you'll have to ship it yourself with Seagate.

Performance
The GoFlex Turbo is a 7,200rpm drive, which is faster than the 5,200-5,400 rpm GoFlex Ultra-Portable drives. With the USB 3.0 interface, it was able to copy our standard test folder in a quick 18 seconds. That's a bit faster than the 21 seconds that it took the previous Editor's Choice Seagate FreeAgent GoFlex Ultra-Portable Drive (500GB) ($99.99 list, 4.5 stars). If you're copying multi-GB files, the time saved is likely to grow. Likewise the GoFlex Turbo excelled at the PCMark 7 test with a high 1,498 point score. We tested the drive with the older PCMark05 test for comparison, and the newer Turbo drive (6,025 points) outpaced the slower GoFlex Ultra-Portable handily (4,794 points). The Turbo drive was a little faster than the older drive under USB 2.0, but by less of a margin. The takeaway is that the Turbo's extra speed makes a difference when you have USB 3.0 on your PC, but less so if you're stuck with USB 2.0. For the quickest speed on a Mac, take a look at the Thunderbolt adapter.

The versatility and speed of the Seagate GoFlex Turbo (750GB) make the drive very attractive, particularly to enthusiasts that need to shuttle data from one PC to another. It works equally well with a Mac and with a Windows PC. It has a larger capacity than the previous Seagate GoFlex portable drive, it's faster than the previous Editors' Choice, and it shares the GoFlex interface and adapter infrastructure. Plus the drive comes with a "free" data recovery session in case things go south with the drive mechanism. It's kind an update rather than a radically new drive, but it's enough to give the GoFlex Turbo our Editor's Choice award for notebook drives and our highest recommendations. If you're looking for a high-performance portable drive that will work with just about any PC or Mac, get a Seagate GoFlex Turbo.

Proposed nuclear clock may keep time with the universe

Accurate to 1/20th of a second in 14 billion years

A proposed new time-keeping system tied to the orbiting of a neutron around an atomic nucleus could have such unprecedented accuracy that it neither gains nor loses 1/20th of a second in 14 billion years - the age of the Universe.

In a paper accepted for publication in the journal Physical Review Letters - with US researchers at the Georgia Institute of Technology and the University of Nevada UNSW's Professor Victor Flambaum and colleague Dr Vladimir Dzuba report that their proposed single-ion clock would be accurate to 19 decimal places.

"This is nearly 100 times more accurate than the best atomic clocks we have now," says Professor Flambaum, who is Head of Theoretical Physics in the UNSW School of Physics.

"It would allow scientists to test fundamental physical theories at unprecedented levels of precision and provide an unmatched tool for applied physics research."

The exquisite accuracy of atomic clocks is widely used in applications ranging from GPS navigation systems and high-bandwidth data transfer to tests of fundamental physics and system synchronization in particle accelerators.

"With these clocks currently pushing up against significant accuracy limitations, a next-generation system is desired to explore the realms of extreme measurement precision and further diversified applications unreachable by atomic clocks," says Professor Flambaum.

"Atomic clocks use the orbiting electrons of an atom as the clock pendulum. But we have shown that by using lasers to orient the electrons in a very specific way, one can use the orbiting neutron of an atomic nucleus as the clock pendulum, making a so-called nuclear clock with unparalleled accuracy."

Because the neutron is held so tightly to the nucleus, its oscillation rate is almost completely unaffected by any external perturbations, unlike those of an atomic clock's electrons, which are much more loosely bound.
