A giant piece of space junk is hurtling towards Earth. Here’s how worried you should be

 

A large piece of space debris, possibly weighing several tonnes, is currently on an uncontrolled reentry phase (that’s space speak for “out of control”), and parts of it are expected to crash down to Earth over the next few weeks. If that isn’t worrying enough, it is impossible to predict exactly where the pieces that don’t burn up in the atmosphere might land. Given the object’s orbit, the possible landing points are anywhere in a band of latitudes “a little farther north than New York, Madrid and Beijing and as far south as southern Chile and Wellington, New Zealand”.

The debris is part of the Long March 5B rocket that recently successfully launched China’s first module for its proposed space station. The incident comes roughly a year after another similar Chinese rocket fell to Earth, landing in the Atlantic Ocean but not before it reportedly left a trail of debris in the African nation of Cote D'Ivoire. At the time, experts noted this was one of the largest pieces of human-made debris ever to fall to Earth. We cannot say with certainty what fate awaits this latest piece of space junk.

The Indian government is silencing its critics on Twitter and Facebook.

A major battle over free speech on social media is playing out in India during the pandemic, As the coronavirus pandemic rages in India, claiming thousands of lives, many Indians are turning to social media to demand that the government handle the public health crisis better. And now, the government is silencing these critics in its latest threat to the future of free speech on the internet in the world’s second-most populous country.

In recent weeks, the Indian government has requested that companies like Twitter take down content that it says contains misinformation about the Covid-19 pandemic. But critics say that India’s political leadership under Prime Minister Narendra Modi is using the premise of misinformation to overreach and suppress criticism of the administration’s handling of the pandemic.

A similar debate has also played out in the US around how companies like Twitter and Facebook should moderate harmful speech on their platforms, particularly when that speech comes from world leaders. But the issue has taken on an increased intensity in India, where the government is more aggressively and directly pressuring tech companies to block content it takes issue with.

“Internet companies are stuck between a rock and a hard place,” said Anupam Chander, a law professor at Georgetown University who focuses on the regulation of international speech online. “They face a government that is accusing them of essentially abetting a violation of law. At the same time, there are huge free expression concerns here.”

Christina Aguilera Talks Confidence and Working Through Insecurities in the Public Eye

 

Over the past 20 years, while Christina Aguilera has been topping the music charts, her voice has been described as soulful and powerful, with just a bit of grit. Interestingly enough, those words also perfectly reflect who she is in her life at this very moment. Having turned 40, the singer says she's been doing a lot of reflection and is determined to live every moment for herself—and to stop worrying about what others think.

As Christina talks about this goal, a mix of vulnerability and determination shines through. "No matter what I've been through—successes, childhood trauma, hardships—I still have a fighting spirit," she says. "I never want to stop learning and growing to be the best person I can be." 

Christina was just 9 years old when she commanded the stage on Star Search. At 13, she more than held her own on The All New Mickey Mouse Club alongside costars Justin Timberlake and Britney Spears. By 19, she had released her debut album and won a Grammy for Best New Artist. In 2002 came her album Stripped. With empowering anthems like "Beautiful," everything about the effort seems to message staying true to yourself. More albums followed, as did roles in movies and TV shows. The other role Christina takes very seriously: being "mama bear" to her kids—Max, 13, and Summer, 6.

So, hearing that she has gotten caught up with what others think? It's a bit surprising. And when we tell Christina that, she laughs—and says that as she's been more open, she's been getting this reaction more and more. But then, she's quick to insist that everyone has their struggles—even world-famous, award-winning singers. 

Bill and Melinda Gates divorce after 27 years of marriage

 

Bill and Melinda Gates have announced their divorce after 27 years of marriage, saying "we no longer believe we can grow together as a couple".

"After a great deal of thought and a lot of work on our relationship, we have made the decision to end our marriage," the pair tweeted. They first met in the 1980s when Melinda joined Bill's Microsoft firm. The billionaire couple have three children and jointly run the Bill & Melinda Gates Foundation.

The organisation has spent billions fighting causes such as infectious diseases and encouraging vaccinations in children. The Gates - along with investor Warren Buffett - are behind the Giving Pledge, which calls on billionaires to commit to giving away the majority of their wealth to good causes.

Bill Gates, 65, is the fourth wealthiest person in the world, according to Forbes, and is worth $124bn (£89bn).

He made his money through the firm he co-founded in the 1970s, Microsoft, the world's biggest software company. The pair both posted the statement announcing their divorce on Twitter. "Over the last 27 years, we have raised three incredible children and built a foundation that works all over the world to enable all people to lead healthy, productive lives,"

The Reason treating Covid-19 with drugs is harder than you think

 

Viruses are much more varied, rapidly evolving and hard to access than bacteria – so scientists searching for drug-based treatments have their work cut out.While there are anti-inflammatory drugs that reduce the risk of death from Covid-19, such as dexamethasone and tocilizumab, they are only given to people hospitalised with severe Covid-19. But Johnson wants drugs that can be taken at home, in pill form, that stop people ending up in hospital on a ventilator.

It usually takes years to develop and approve new antiviral drugs because the discovery pipeline involves a painstaking process of identifying chemical compounds that target the virus and then testing their efficacy and safety. For this reason, scientists are also looking at reusing existing drugs that have been approved for treating other viruses or diseases.

Unlike broad-spectrum antibiotics, which can be used to treat a wide range of bacterial infections, drugs that work against one type of virus rarely work at treating other viruses. For example, remdesivir, originally developed for treating hepatitis C, was at one point suggested as a treatment for Covid-19, but clinical trials have shown that it has only a limited effect against this coronavirus.The reason there are few effective broad-spectrum antivirals is that viruses are much more diverse than bacteria, including in how they store their genetic information (some in the form of DNA and some as RNA). Unlike bacteria, viruses have fewer of their own protein building blocks that can be targeted with drugs.

For a drug to work, it has to reach its target. This is particularly difficult with viruses because they replicate inside human cells by hijacking our cellular machinery. The drug needs to get inside these infected cells and act on processes that are essential for the normal functioning of the human body. Unsurprisingly, this often results in collateral damage to human cells, experienced as side-effects.Targeting viruses outside cells – to stop them from gaining a foothold before they can replicate – is possible, but is also difficult because of the nature of the virus shell. The shell is extraordinarily robust, resisting the negative effects of the environment on the way to its host. Only when the virus reaches its target does its shell decompose or eject its contents, which contain its genetic information.

Navy SEAL teams plagued by "lawlessness" within their ranks

 

Both former and active-duty Navy SEALs are sounding the alarm over well-documented cases of criminality, drug use and exploitation of the elite military unit's brand, just as they prepare to mark 10 years since a SEAL team killed Osama bin Laden in a daring raid in Pakistan.

Ceniplug News senior investigative correspondent Catherine Herridge spoke with more than a dozen people in the SEAL community, including current and former SEALs,  on the condition of anonymity. They told her that while the vast majority of their fellow SEALs serve honorably, there is a corrupt element in their brotherhood.

"We love the job. We love the community. But it has taken a wrong turn," one SEAL told Herridge.

Three of them agreed to sit down with ceniplug News for interviews on the condition that their voices be changed and their identities hidden. 

Days after September 11, 2001, standing at Ground Zero in New York, President George W. Bush launched a massive global manhunt for the chief culprit behind the terror attacks. A decade later, the search ended at a compound in Abbottabad, Pakistan, where SEAL Team 6 had zeroed in on Osama bin Laden

Herridge asked the three SEALs who spoke to CBS News why they'd insisted on hiding their identities. "We are risking a lot to be here, risking careers, possible safety," replied one of the men. The group claims there are bad SEALs who have outsized influence on the teams.

New Heart Health Guidelines Focus on Belly Fat, Not Just Body Weight

 

When it comes to assessing your risk for heart disease, you need to think not only about how much you weigh, but where you carry any extra pounds. That’s because people who have what’s considered a healthy weight based on their body mass index (BMI) can still have an increased risk for heart disease if they have extra fat around their midsection, according to guidelines from the American Heart Association (AHA) published in April 2021 in Circulation.

This means that even if you’re not overweight, your next physical should involve a tape measure around your waist in addition to a check of your height and weight, according to the AHA. That’s because a growing body of evidence suggests that extra belly fat is a sign that you may have too much so-called visceral adipose tissue, a type of fat that wraps around abdominal organs and is a risk factor for cardiovascular disease. “Having more visceral adipose tissue is associated with greater risk of cardiovascular disease at all BMI levels,” says Marie-Pierre St-Onge, PhD, senior author of the AHA guidelines and an associate professor of nutritional medicine at Columbia University Irving Medical Center in New York City.

Foods to Avoid If You Have Sensitive Teeth

 Having sensitive teeth is common: As many as 40 million Americans report having some pain in their teeth when eating or drinking hot, cold, acidic, sticky, or sugary foods, according to the Academy of General Dentistry (AGD).  Women and young adults as well as those with receding gum lines reported the most tooth sensitivity in a study of nearly 800 patients at dental practices in the northwestern United States that was published in The Journal of the American Dental Association in March 2013.

While foods that are very hot or very cold can cause tooth pain, avoiding these eight foods in particular may help you find relief:

Tooth Sensitivity

 

Tooth sensitivity occurs when hot, cold, sweet, or acidic substances irritate tooth nerves.

What Causes Sensitive Teeth?

Teeth are covered by a protective substance called enamel. Under the gum line, the protective substance is called cementum. The layer under the enamel and cementum is the dentin. Dentin supports the enamel and protects the tooth pulp and nerve root in the middle of the tooth. A series of small tubes (tubules) runs through the dentin. Erosions in enamel and cementum allow substances to come into contact with tubules, which irritates the tooth nerve and results in pain. Cavities, gum disease, cracks in teeth, and enamel erosion may all contribute to tooth sensitivity.

How to Reduce Tooth Sensitivity

Treatments may include the use of toothpaste or fluoride gel that blocks pain sensation. A dentist may apply a crown or bonding material over the sensitive area. A gum graft may be necessary to cover a sensitive area in which gums have receded.

What Are the Three Most Common Symptoms of Undiagnosed Diabetes?

 

Diabetes is a metabolic disorder that happens when blood sugar (glucose) is too high (hyperglycemia). Glucose is the body’s main source of energy, and the pancreas produces the hormone insulin that converts glucose from the food you eat into energy the body uses. When the body doesn’t make enough insulin or doesn’t produce any at all, or the body becomes insulin resistant, glucose doesn’t reach the cells to be used for energy. This results in diabetes. 

Types of diabetes include:

Type 1 diabetes (formerly called juvenile diabetes) is an autoimmune condition in which the body does not produce insulin 

Type 2 diabetes, the most common form of diabetes, is a condition in which the body does not produce adequate insulin or does not use it efficiently

Gestational diabetes develops in some women during pregnancy and usually goes away after the baby is born

6 crucial steps to a good night’s sleep, according to an insomnia expert

 

• Sleep is defined as a state of unconsciousness from which a person can be aroused, therefore, external stimuli have no effect. In this state, the brain is relatively more responsive to internal stimuli than external stimuli.
• Sleep should be distinguished from coma. Coma is an unconscious state from which a person cannot be aroused.
• Sleep is essential for the normal, healthy functioning of the human body. It is a complicated physiological phenomenon that scientists do not fully understand.
• Historically, sleep was thought to be a passive state. However, sleep is now known to be a dynamic process and our brains are active during sleep.
• Sleep affects our physical and mental health and is essential for the normal functioning of all the systems of our body, including the immune system. The effect of sleep on the immune system affects one's ability to fight disease and endure sickness.
• Brain activity during sleep and wakefulness is a result of different activating and inhibiting forces that are generated within the brain. Neurotransmitters (chemicals involved in nerve signaling) control whether one is asleep or awake by acting on nerve cells (neurons) in different parts of the brain.
• Neurons located in the brainstem cause sleep by inhibiting other parts of the brain that keep a person awake.

The past year has wreaked havoc with our sleeping patterns, you know this already but studies back it up. Yet sleep has a huge impact on our emotional and physical wellbeing, and a chronic lack of it puts you at greater risk of obesity and developing certain conditions, such as heart disease and diabetes. If you are one of the many currently struggling with shuteye, help is at hand. Insomnia specialist Kathryn Pinkham, founder of The Insomnia Clinic and a Boots sleep expert, has shared some of her top tips for getting a good night's kip.

Build your 'sleep drive'

“In order to fall asleep quickly and get good quality sleep we need to build up a strong ‘sleep drive,’” Pinkham explains. “This is basically an appetite for sleep – the longer we have been out of bed, the bigger our appetite. “ Our bodies are designed to build up a sleep drive during the day and go to sleep when the drive is highest “to take back the debt we have been building.”  Going to bed early and waking later will mean you struggle to fall asleep or wake throughout the night (or both) as your sleep drive is simply not strong enough, so the best way to strengthen your sleep drive is to shorten the amount of time you spend in bed.“Most poor sleepers tend to go to bed early or lie in in an attempt to get more sleep, but this results in a weak sleep drive. Try going to bed later and setting your alarm earlier, even if it’s only 30 minutes each end of your sleep window; you’re creating a much stronger sleep drive which results in better quality sleep,” she says.

Ryan Giggs appears in the dock to deny assaulting his ex-girlfriend and her younger sister

 

Former Manchester United footballer Ryan Giggs is accused of “humiliating and degrading” his ex-girlfriend during a three-year relationship, a court heard today.

The 47-year-old appeared in the dock at Manchester and Salford magistrates court today, facing three criminal charges including alleged attacks on two women.It is said Giggs caused actual bodily harm to his ex-girlfriend, PR executive Kate Greville, 36, at his home in Worsley, Greater Manchester on November 1 last year.

He has also been charged with engaging in coercive or controlling behaviour against Ms Greville between December 2017 and November last year. And the former winger is accused of the common assault of Ms Greville’s younger sister Emma during the same incident last November. Appearing in the dock with his hands clasped in front of him, Giggs entered not guilty pleas to the charges. Prosecutor Andrea Griffiths said Giggs’s alleged offending began at the start of their romance.

Deputy Chief Magistrate Tan Ikram sent the case to be tried by a jury, freeing Giggs on bail until a hearing at Manchester crown court on May 26. The former footballer, wearing a suit and black face mask, was greeted by calls of “Giggsy” as he arrived at court today shortly before 10am. He stepped back from his role as Wales manager after reports of his arrest last November, in the wake of a disturbance at his home.

Woman who didn’t return VHS tape for 22 years charged with felony

 

She was on tape delay.

A Texas woman learned earlier this week that she was a wanted felon for not returning a 22-year-old VHS tape. Caron McBride lived in Oklahoma when she rented the copy of “Sabrina the Teenage Witch” in 1999, Oklahoma City Fox affiliate KOKH reported. The Norman, Okla., store she rented it from, Movie Place, went out of business in 2008.

In March 2000, McBride was charged with felony embezzlement after the tape was not returned, according to KOKH.

“I had lived with a young man, this was over 20 years ago,” McBride told the station. “He had two kids, daughters that were 8, 10 or 11 years old, and I’m thinking he went and got it and didn’t take it back or something. I have never watched that show in my entire life, just not my cup of tea.”

McBride learned about the charges while trying to change her name on her driver’s license after getting married in Texas, KOKH reported. The local district attorney in Oklahoma dismissed the case Wednesday after reviewing it.

“I mean, I didn’t try to deceive anyone over ‘Samantha the Teenage Witch.’ I swear,” McBride said, getting the title character’s name wrong and indirectly strengthening her case that she never watched the show.

McBride told KOKH she lost multiple jobs over the past 20 years for unexplained reasons. She will have to sue the state of Oklahoma to clear her record.

How to Cure Adrenal Fatigue Fast

Source

Have you been watching the news, and now feel very stressed out? Well, if you've been stressed more than usual lately, you might be experiencing adrenal fatigue. Keep on scrolling down to how to help cure adrenal fatigue effectively. 

What is adrenal fatigue? 

Let's dive into biology 101. Your adrenal glands produce different hormones that are essential to the function of your body. They're about the size of a nickel and sit above your kidneys. One of the hormones that they produce is cortisol, which correlates to stress. Adrenal fatigue happens when you push your body to the point where it is experiencing chronic stress. When this happens, your body stops producing cortisol as it should. Adrenal fatigue causes various symptoms, including body aches, fever, fatigue, nervousness, low energy, and digestive problems.
