A sleep expert explains why naps can be dangerous for your health

Sleep expert Matthew Walker explains how naps can negatively impact your body. Following is a transcript of the video.

Matthew Walker: My name is Matthew Walker. I am a professor of neuroscience and psychology at the University of California Berkeley and I am the author of the book, "Why We Sleep."

Should we actually be taking naps during the day? Well, we certainly know from evidence in my own sleep center and that of many other scientists that naps can give you benefits for both your brain and your body. But naps can actually be a double-edged sword because whilst we're awake during the day, we're building up sleepiness or sleep pressure. So that when you try to fall asleep at night, you'll fall asleep quickly and then you'll stay asleep. And when we sleep, we actually release that sleepiness, almost like a valve on a pressure cooker, so that we wake up the next morning feeling refreshed.

Celebrities Who Faced Prostate Cancer

In early October 2016, actor and comedian Ben Stiller, now 51, shocked fans and colleagues when he announced he had been diagnosed with prostate cancer two years earlier.

But he wasn’t alone: More than 200,000 American men are diagnosed with prostate cancer each year, according to the National Cancer Institute (NCI). It occurs when cells in the prostate – a male gland that produces seminal fluid – start to grow uncontrollably. In many cases, it’s a slow-growing cancer, and treatments range from careful monitoring to surgery, radiation and chemotherapy, the NCI says.

The American Cancer Society advises most men to begin testing for prostate cancer at age 50. Screening is recommended at age 45 for African Americans and those with a close relative who was diagnosed with the disease before they were 65; those with more than one close relative should start tests at 40.

Read on to learn about Stiller and other famous men who have been diagnosed with prostate cancer.

Leukaemia treatment can be made more effective by using a drug for iron overload

Chemotherapy for one type of leukaemia could be improved by giving patients a drug currently used to treat an unrelated condition, new research shows.

Acute myeloid leukaemia (AML) is an aggressive cancer that stops healthy blood cell production. Chemotherapy is the standard treatment, but improvements are needed as the five-year survival rate in patients older than 60 is only 5-15 per cent.

Now, by studying how leukaemia cells infiltrate bone marrow, where blood cells are created, researchers led by a team from Imperial College London have made a crucial discovery.

Studying mice and human samples, they found that certain areas in the bone marrow support blood stem cells, and when these are overtaken by leukaemia cells, these stem cells are lost and production of healthy blood is significantly reduced. This can cause anaemia, infection, and bleeding in patients, and affects the success of chemotherapy.

The memes that took over Korea’s internet in 2017 show people are done with elites and corruption

Despite a year of unrelenting provocations from North Korea that has sent the globe into a state of alarm over the prospect of war on the Korean peninsula, South Koreans will more likely remember 2017 as the year the people brought down a president and installed a new, progressive leader in power.
As such, it was no surprise that memes related to the downfall of disgraced president Park Geun-hye and the subsequent election of the affable and humble former human-rights lawyer Moon Jae-in dominated the internet in 2017.


Face hegemony

Not only is president Moon wildly popular in Korea, but so are the people around him. Together with senior secretary for civil affairs Cho Kuk, chief of staff Im Jong-seok, and the president’s bodyguard, the popularity of this group of handsome men lies partly in their “face hegemony.” Moon and his cabal have been dubbed the “F4,” or “Flower 4” (link in Korean) of the presidential Blue House, after the moniker given to the four male heartthrobs in the Korean TV series Boys Over Flowers.

NASA Astronaut, 1st to Fly Untethered in Space, Dies at 80

NASA astronaut Bruce McCandless, the first person to fly freely and untethered in space, has died. He was 80.

He was famously photographed in 1984 flying with a hefty spacewalker's jetpack, alone in the cosmic blackness above a blue Earth. He traveled more than 300 feet away from the space shuttle Challenger during the spacewalk.

“The iconic photo of Bruce soaring effortlessly in space has inspired generations of Americans to believe that there is no limit to the human potential,” Sen. John McCain said in a statement. The Arizona Republican and McCandless were classmates at the U.S. Naval Academy.

Diet rich in apples and tomatoes may help repair lungs of ex-smokers, study suggests

A study from the Johns Hopkins Bloomberg School of Public Health found the natural decline in lung function over a 10-year period was slower among former smokers with a diet high in tomatoes and fruits, especially apples, suggesting certain components in these foods might help restore lung damage caused by smoking.

The researchers found that adults who on average ate more than two tomatoes or more than three portions of fresh fruit a day had a slower decline in lung function compared to those who ate less than one tomato or less than one portion of fruit a day, respectively. The researchers inquired about other dietary sources such as dishes and processed foods containing fruits and vegetables (e.g. tomato sauce) but the protective effect was only observed in fresh fruit and vegetables.

Argentina submarine: Police raid navy and German company offices

Argentine police have raided navy shipyards as a probe into repair irregularities deepens. One of the two German companies implicated in the sub's repairs, Ferrostaal, has also had its local offices searched.
Argentine police searched through navy headquarters and state-run shipyard offices on Wednesday in a bid to investigate the disappearance of a submarine last month.
A judge ordered the searches to help probe alleged irregularities with repairs on the German-built submarine.
The searches came after the navy appeared to implicate two German companies Ferrostaal and Hawker, for electrical repair problems with the submarine. Argentine authorities on Wednesday also searched the Buenos Offices of Ferrostaal.

Ukraine arrests official who doubled as 'agent of Russian intelligence'

Ukraine's state security service (SSU) on Thursday arrested a government official they claim was doubling as an "agent of Russian intelligence." The official formed part of Prime Minister Volodymyr Groysman'sinner circle, according to authorities.
"Together with the Security Service of Ukraine, an official in the government's secretariat was found to be working for a long time in the interests of the enemy state. He was detained," Groysman said in a post on Facebook.
Kremlin spokesman Dmitry Peskov said Russian authorities are aware of the arrest, "but we have no information," reported state-owned TASS news agency.

Authorities did not provide a name or position for the suspect, but local media reported that Stanislav Yezhov, the premier's assistant, had been detained a day earlier.
Yezhov reportedly accompanied Groysman on all international trips during his time as assistant, and previously worked in the president's office and the Ukrainian embassy in the US. Ukraine's state security service said he had been recruited by Russia's Federal Security Service (FSB).

These Canned Foods Are Destroying Your Health — Avoid Them at All Costs

it’s pretty amazing how many foods we’ve preserved in a can over the years. The usual suspects, such as tuna fish, beans, and soup, probably come to mind first and foremost. But if you peruse your local grocery store aisles, there are hundreds of cans left and right. You might have even popped open a can of food to add to a meal today and didn’t even think twice about it.
Canned foods certainly have their place. But not every canned food is good for you. There are plenty that sound convenient and tasty but are truly horrible for your health. Let’s take a quick look at 11 canned foods that are destroying your health (No. 6 might be too tasty to give up). We’ll also take a brief look at which canned foods are actually good for you.

Regular Exercise, Vitamins, Brain Training, Or A Healthy Diet Can't Prevent Dementia: Study

There is no method that has been proven to prevent the occurrence of dementia later in life, according to an analysis of numerous studies.

A team of researchers from the Minnesota Evidence-based Practice Center wanted to see whether vitamins and supplements, brain training, prescription medications, or physical activity can help in preventing dementia.

The researchers wanted to analyze possible interventions for dementia because the number of dementia patients is expected to rise sharply as the population ages.

The team, however, found that none of the interventions was successful and nothing seemed to prevent the condition after analyzing four systematic reviews and their findings. The researchers published their paper in the journal Annals of Internal Medicine.

Notable deaths of 2017 -- Hugh Hefner, Edith Windsor, Charles Manson,Tagbo, Jerry Sutol O, and others we lost this year

 

Beloved celebrities, athletes that transcended generations and innocent people gunned down in two of the most horrific mass shootings in modern United States history were all taken from us in 2017.

One of the first notable losses of the year came in January with the passing of legendary actress Mary Tyler Moore. The television icon who starred in "The Mary Tyler Moore Show" and "The Dick Van Dyke Show" was one of the most beloved actresses in modern history. She was diagnosed with Type 1 diabetes in her early thirties and went on to become an advocate for the Juvenile Diabetes Research Foundation.

Female pioneers who helped shape our history were lost this year, including Clare Hollingworth, a veteran war correspondent widely known for breaking the news that WWII had started, died at the age of 105 in January.

Norma McCorvey was also among the year's deaths. She was the person behind the anonymous "Jane Roe" in the landmark Roe v. Wade case, which ultimately led to the legalization of abortion in the United States in the 1970s. McCorvey eventually split from pro-choice activists and joined the pro-life movement to advocate against abortion, despite her role in its legalization.

Amber alert issued for Houston baby after mother stabbed to death

Authorities have issued an Amber Alert for an infant girl in Houston who was reported missing after her mother was found fatally stabbed. Police initially believed the infant girl was with her father, but Houston police said later that they had found the father in San Antonio, but the 6-week-old baby was still missing.

Houston police said Thomas Bernardez "stated he was not involved in the murder."

Pastor to give money from sale of 709-carat "Peace Diamond" to the poor

An African pastor's miracle discovery of a massive uncut diamond has just been sold at auction so the community leader can bring clean water and medical supplies to his village, CBS Denver reports. The 709-carat "Peace Diamond" was discovered in the village of Koryardu in March.

The diamond's owner, Pastor Emmanuel Momoh, vowed to sell the gem in order bring the struggling village the relief it needed.

"The Peace Diamond will greatly improve the lives of our people as it will bring clean water, electricity, schools, medical facilities, bridges and roads to our villages and the Kono District," Momoh said in a statement, obtained by Forbes.

After an initial offer for the world's 14th largest diamond was rejected by Sierra Leone's government in May, the stone went back on the auction block and sold for $6.5 million in New York on Dec. 4. The hefty price tag, which is actually $1.3 million less than the offer in May, was paid by British jeweler Graff Diamonds.

Eric Lefkofsky: One Of The Most Unique Entrepreneurs Of Our Time

Eric Lefkofsky is a Jewish-American entrepreneur who is the co-founder and CEO of Tempus. It was his desire to help people who suffer from cancer that motivated him to take part in Tempus, which is a company that has made it its mission to change the way that cancer is dealt with. They are continuing to do so and have already done so by creating a database of information that draws from the treatment of previous cancer patients. In doing so, new patients can receive better focused treatment because their physicians have the kind of information in their hands that allows them to make decisions based on solid scientific data rather than taking shots in the dark.

The Athletics Integrity Unit and the US Anti-Doping Agency are seeking urgent answers from Gatlin’s camp after it was claimed his coach Dennis Mitchell and agent Robert Wagner offered to supply testosterone and human-growth hormone to an undercover reporter.

The Daily Telegraph newspaper alleged that, in an undercover investigation, Mitchell and Wagner had offered to supply banned drugs for an actor training for a film.

Undercover reporters visited Gatlin's Florida training camp and they claim the pair offered to supply and administer testosterone and human growth hormone.

More than 6,500 inmates are linked to increase in smuggling of drugs, weapons and phones into prisons

More than 6,500 prisoners linked to organised crime gangs are helping orchestrate smuggling rackets behind bars, a new study has found.
One in every 13 of England and Wales' 85,500 inmates are involved in, or have connections to, gangs sneaking drugs, weapons and mobile phones over the walls.
The figure, calculated by the National Crime Agency and the Prison Service, reveals for the first time the scale of a problem fuelling a surge in violence and disorder in jails.
Justice Secretary David Lidington used a keynote speech yesterday to warn that smuggling gangs were attacking prisons to exploit the 'captive market'.
Illegal operations to sneak contraband into jails had changed from 'crude and opportunistic' to 'sophisticated and systematic' – including the use of new technologies including smartphones and drones.
He said: 'The fact is, our prisons are facing a clear and present danger from well-organised individuals and criminal networks.
'These are networks that are every bit as professionally operated as a legitimate business but they happen to be engaged in criminal activity.

Victim of horror crash which killed six people was drug dealer who once led police on terrifying 120mph chase

A victim of a horror crash which claimed the lives of six people was a drug dealer who once led police on a terrifying 120mph chase.

Kasar Jehangir was in a high-powered Audi S3 with three friends which slammed head-on into a taxi in Birmingham on Sunday.

The 25-year-old and pals Tauqeer ‘Tokx’ Hussain, 26, and Mohammed Fasha 30, died in the crash.

Taxi driver Imtiaz Mohammed, 33, and his two passengers - a man aged 42 and woman aged 43 - were also killed.

Zakkria Khan, 22, who was in the Audi, survived the crash and remains in a serious but stable condition in hospital.

It emerged tonight that Jehangir had only recently been released from prison.

Breast Cancer in Young Women

Breast cancer is more common in older adults. At age 30, a woman’s risk of getting the disease is 1 in 227. By age 60, a woman has a 1 in 28 chance of receiving this diagnosis. Although the odds are much lower for younger women, they can and do get breast cancer. More than 13,000 women ages 40 or under will be diagnosed this year.

When breast cancer is diagnosed at a young age, it’s more likely to be aggressive and to spread quickly. Young women may not get a diagnosis right away because many organizations don’t recommend regular mammogram screenings until age 45 or 50. It’s also harder for doctors to find breast cancer in young women than in older women because younger women have denser breasts. This means that they have more breast tissue than fat tissue. Tumors don’t show up as well on mammograms in women with dense breasts.

Read on to learn about some of the unique challenges young women with breast cancer face and what to do if you’ve been diagnosed.

Kaká announces his retirement, wrapping an elite pro soccer career

aká announced his retirement Sunday, officially wrapping an elite pro soccer career that included a final stop helping Orlando City make the jump to Major League Soccer.

The 35-year-old midfielder said in October he would not renew his contract with Orlando City, passing on an offer that would pay him less than the original $7.167 million deal he first signed when the Lions were joining MLS.

Kaká left open the possibility he would play one more year in his native Brazil, take a year off before playing again or retire. More recently, he was linked to a possible return to Italian club A.C. Milan.

He announced his decision to wrap up his career as a player on his social media accounts, posting a picture of himself kneeling on a pitch next to a soccer ball while wearing a T-shirt that read, “I belong to Jesus.”
