Ebola Can Survive in Men Cement For More Than 2 Years

Ebola may linger in men’s semen for more than two years, a new study suggests.

What’s more, at least one man who survived Ebola and then tested negative for the presence of the virus in his semen later tested positive, the new study found.

The findings raise questions about how long Ebola can linger in special immune hideouts in the body. However, the new findings only show some men carry RNA or genetic material from Ebola long after recovering from the disease. They don’t necessarily mean all men who test positive for Ebola RNA are still capable of transmitting the virus. [What Are the Long-Term Effects of Ebola?]

Ebola virus is a rare and deadly virus that starts with common flu-like symptoms, such as fever, muscle and joint pain, and headache, according to the Centers for Disease Control and Prevention. As the virus progresses, however, people suffer from extreme diarrhea and vomiting, and in the late stages of the disease, people’s blood vessels may become leaky, causing bleeding from the rectum, nose or mouth. People infected with the virus can

Anorexia Following Causes, Symptoms & Treatment

Anorexia nervosa involves an extreme obsession with limiting food intake and weight that can end up taking over a person’s life. It is defined as a perceived intense need to drastically limit food intake to produce weight loss.

Anorexia is often thought to affect mostly women. “There is evidence that this is the case, but also conflicting information that boys are equally anorexic but it goes unnoticed and underreported,” said Jeanette Raymond, a licensed psychologist. Anorexia affects 0.9 percent of American women, according to the National Association of Anorexia Nervosa and Associated Disorders (ANAD). From 5 to 10 percent of people diagnosed with anorexia are male, according to the University of Pittsburgh.

Anorexia is not really about food, according to the Mayo Clinic. People with anorexia are looking for a way to cope with emotional problems, so they try to find something in their life they can control. Food is something that is a constant in a person’s life, so it can be controlled.

As with many mental-health conditions, the exact causes of anorexia are difficult to pinpoint. Scientific research has helped to

Is Drinking Less Reducing Your Diabetes Risk?

Is alcohol good or bad for your health? With no shortage of contradictory findings, it’s understandable if you’re left feeling like you’ve had a little too much to drink.

Now, new research from Denmark suggests that moderate levels of alcohol drinking — not binge drinking — may be linked to a lower risk of developing diabetes. But it’s not just how much people drink, but how often they drink, that plays a role, the researchers said.

It’s important to note, however, that most experts recommend that if you don’t already drink alcohol, you shouldn’t start because of possible health benefits.

In the study, published today (July 27) in the journal Diabetologia, researchers found that drinking alcohol three to four days a week was associated with a lower risk of diabetes compared with drinking less than one day a week. [7 Ways Alcohol Affects Your Health]

The “findings suggest that alcohol drinking frequency is associated with risk of diabetes, and that consumption of alcohol over three to four days per week is associated with the lowest risk of diabetes, even after taking average weekly alcohol

Swipe left for sadness: Reminder users report more grief

Swiping through Tinder may be taking a toll on your mental health and self-esteem: A new study finds that Tinder users had lower levels of self-esteem and more body dissatisfaction than people who didn’t use the dating app.

The reason may have to do with the fact that a person’s looks play a major role in Tinder. People accept or reject potential matches based primarily on photos, and sometimes, a short description. And this type of judgment can take a toll, the study found.

Both male and female Tinder users in the study experienced low self-esteem, body shame and negative moods, said lead study author Jessica Strubel, an assistant professor of textiles, merchandising and design at the University of Rhode Island, whose research includes looking at the effects of body image on decision-making. [13 Scientifically Proven Signs You’re in Love]

Strubel has studied the links between Tinder and self-esteem before. In astudy published online earlier this year, she found that male Tinder users had lower self-esteem than men who weren’t on the app.

In the new study, which was presented here today (Aug. 3) at the American Psychological Association’s annual meeting, Strubel and her

Scientists Have Removed Heart Disease Defects on Human Embryos

A group of scientists in Oregon has successfully modified the genes of embryos using CRISPR, a cut-and-paste gene-editing tool, in order to correct a genetic mutation known to cause a type of heart defect.

The experiments, which were described today (Aug. 2) in the journal Nature, were conducted by biologist Shoukhrat Mitalipov and colleagues at Oregon Health & Science University in Portland. Mitalipov conducted the experiments on dozens of single-celled embryos, which were discarded before they could progress very far in development, MIT Technology Review reported last week when the results were initially leaked. This is the first time that scientists in the United States have used this approach to edit the genes of embryos.

The CRISPR/Cas9 gene-editing system is a simple “cut and replace” method for editing precise spots on the genome. CRISPRS are long stretches of DNA that are recognized by molecular “scissors” called Cas9; by inserting CRISPR DNA near target DNA, scientists can theoretically tell Cas9 to cut anywhere in the genome. Scientists can then swap a replacement gene sequence in the place of the snipped sequence. The replacement sequence then gets automatically incorporated into the genome by natural DNA

After Terrorist Attacks, Too Much TV Can Be Dangerous

During a terrorist attack, it may be best to avoid wall-to-wall news coverage, a new study suggests.

Watching television news coverage during terrorist events was associated with higher levels of post-traumatic stress and feelings ofdepression as well as decreased feelings of safety, the researchers found.

In the study, which was presented here today (Aug. 3) at the annual meeting of the American Psychological Association, the researchers focused on a terrorist event that captured news coverage in 2002: a series of sniper attacks in the Washington, D.C., area that killed 10 people and left three others wounded. Local media covered the events extensively as they unfolded. [7 Ways Depression Differs in Men and Women]

“We understand that [the] media plays a critical role in people’s feelings of safety or feelings of threat in the environment,” said lead study author Holly Mash, a research assistant professor of psychiatry at the Uniformed Services University of the Health Sciences in Bethesda, Maryland.

Mash and her colleagues had more than 1,200 people complete online questionnaires about their moods and feelings during the sniper attacks. In addition, the researchers collected data on how much sniper-related TV the people watched each

Western Men See Drop in Sperm Counts, But The Cause Is Still Unknown

Sperm counts among men in Western countries have dropped considerably in the last several decades, according to a new study.

Researchers analyzed information from 185 previous studies involving a total of more than 42,000 men in 50 countries. These men had all given semen samples for research, but typically not for reasons related to fertility problems. For example, some were college students, or were men who were undergoing health screenings before entering military service.

The results showed that, from 1973 to 2011, there was a decline of more than 50 percent in sperm counts among men living in North America, Europe, Australia and New Zealand.

The researchers said that they cannot determine from their data what might have caused the decline, but it could be related to environmental or lifestyle factors. The findings are concerning, not only because men’s sperm counts are linked with their chances of conceiving a child, but also because poor sperm counts have been linked with a number of other poor health outcomes, including an increased risk of early death.

“Given the importance of sperm counts for male fertility and human health, this

Penis Enlarger Leads Human Death! Here’s his Explanation

A man in Sweden died just after penis enlargement surgery, according to a new report of the case.

As a part of the procedure, doctors injected fat into the healthy 30-year-old man’s penis, according to the report, written by pathologists who examined the man’s body after his death. Some of this fat entered the man’s veins, and then traveled through the blood to his lungs. When fat droplets enter the small blood vessels in the lungs, they can cause blockages, and the body can’t properly absorb oxygen, leading to death.

This type of blockage, called a fat embolism, is a known risk of moving fat from one part of the body to another, said Dr. Lee Zhao, a urologist at NYU Langone Health in New York City, who was not involved in the man’s case. Still, “it’s an extremely rare event,” Zhao added. [8 Wild Facts About the Penis]

But it’s not clear from the case report exactly where in the penis the fat was injected, Zhao told Live Science.

“The penis works by filling erectile tissue with blood,” Zhao said. “If the fat was injected into the erectile tissue, then the risk of

Will talcum powder Could cause ovarian cancer?

Some people may sprinkle on powder after showering and never think much of it. But recent court cases have shined a spotlight on the possible link between women’s regular use of talcum powder on their genitals and an increased risk of developing ovarian cancer.

Yesterday (Aug. 21), a jury in Los Angeles ordered Johnson & Johnson to pay a record $417 million to a woman who claims that the company’s baby powder led to her ovarian cancer. The woman, Eva Echeverria, said in the lawsuit that she developed ovarian cancer as a “proximate result of the unreasonably dangerous and defective nature of talcum powder,” according to the Associated Press. (Johnson & Johnson’s baby powder is made from talcum powder or talc, which is a mineral made up of magnesium, silicon and oxygen.)

In a case that was settled in February, a jury determined that the family of a 62-year-old Alabama woman, who died from ovarian cancer in 2015 after decades of using talcum powder for feminine hygiene, was entitled to $72 million in damages from Johnson & Johnson. The company did not inform customers of the potential dangers of its powders despite being aware of the

Friends with Ex Check Your First Motive, Science Says

Can you really stay friends with an ex? It depends on why you want to continue the relationship, a new study finds.

Staying friends with an ex is a “very pervasive phenomenon,” said lead study author Rebecca Griffith, a master’s student in psychology at the University of Kansas. Indeed, previous research suggests that about 60 percent of people maintain a friendship after a breakup, Griffith said.

But these friendships aren’t always successful.

In the study, the researchers developed a way to examine the reasons why a person might stay in a friendship after ending a romantic relationship. In one experiment, which included more than 170 women and more than 110 men, the researchers tried out this new measurement technique, which consisted of several questionnaires. In a second experiment, with nearly 300 women and nearly 250 men, the researchers confirmed that the questionnaires worked. [The Science of Breakups: 7 Facts About Splitsville]

The researchers found that are four main reasons that someone stays friends with an ex after a breakup, said Griffith, who presented the study here on Aug. 4 at the American Psychological Association’s annual meeting.

The first reason is security, Griffith told
