Study shows social media may harm teens' mental health
CNN's Dr. Sanjay Gupta explains the details of a new study linking social media use to mental health issues in teens.
How Does Social Media Affect Girls? They Feel Effects More Strongly Than Boys, New Research Says

Straight men fear that recycling makes them look gay
One study, Sex Roles, explores the idea of society associating genders with specific environmentally-friendly behaviors.
It shows that straight men are avoiding pro-green behaviors in the fear that they might be accused of being gay.
They also fear that making small changes like using reusable bags, disposing of waste correctly, and using more public transport could damage their masculinity.
More than half of U.S. beaches have fecal bacteria, environmentalists say
While Massachusetts beachgoers may be worried about sharks this summer, environmentalists are warning about a much smaller organism. E. coli, a bacteria present in animal and human waste, could hurt many more people—and it shows up on half of America's beaches, according to new research from Environment America and the Frontier Group.
Half the beaches in the U.S. have at least one day per summer season in which it's not safe to swim because of elevated bacteria levels in the water, according to a report the group released recently. Some states had it much worse. In Louisiana, all of the 24 beach sites sampled were potentially unsafe for at least one day last summer. In Mississippi, all 21 of 21 beach sites sampled were.
There are several ways for bacteria to get into water, but two of the most common ones are overflows from sewage treatment plants or runoff during heavy rain.
Playing video games does not make you a mass shooter, expert says
During a speech on Monday addressing the recent mass shootings in El Paso, Texas and Dayton, Ohio, President Trump call for an end to — or substantial reduction of — the "glorification" of violence in "gruesome and grisly" video game culture. While some are quick to blame video games for real-life acts of violence, experts say there is no such link.
"When it comes to actual serious criminal violence, there's virtually no evidence that video games matter," James Ivory, professor and research director at Virginia Tech, told CBS News.
Ivory has researched the social and psychological dimensions of media, particularly the content and effects of video games. He says he's determined that a lot of things influence violent crime — but the media we consume is not one of them.
First human-monkey chimera raises concern among scientists
Efforts to create human-animal chimeras have rebooted an ethical debate after reports emerged that scientists have produced monkey embryos containing human cells.
A chimera is an organism whose cells come from two or more “individuals”, with recent work looking at combinations from different species. The word comes from a beast from Greek mythology which was said to be part lion, part goat and part snake.
The latest report, published in the Spanish newspaper El País, claims a team of researchers led by Prof Juan Carlos Izpisúa Belmonte from the Salk Institute in the US have produced monkey-human chimeras. The research was conducted in China “to avoid legal issues”, according to the report.
Chimeras are seen as a potential way to address the lack of organs for transplantation, as well as problems of organ rejection. Scientists believe organs genetically matched to a particular human recipient could one day be grown inside animals. The approach is based on taking cells from an adult human and reprogramming them to become stem cells, which can give rise to any type of cell in the body. They are then introduced into the embryo of another species.
22 percent of millennials say they have “no friends”
Today, members of the millennial generation are ages 23 to 38. These ought to be prime years of careers taking off and starting families, before joints really begin to ache. Yet as a recent poll and some corresponding research indicate, there’s something missing for many in this generation: companionship.
A recent poll from YouGov, a polling firm and market research company, found that 30 percent of millennials say they feel lonely. This is the highest percentage of all the generations surveyed.
The life expectancy for every country in the world
Why it matters: The developed world is having fewer children and will soon have a much larger population of retired, elderly people with health care needs. This is likely to cause significant financial strain on government programs and the labor force in many countries. But if people are staying healthy longer, it could lessen some of those economic impacts.
Key quote: "There’s a potential for some significant positive offset through higher elderly workforce participation," Richard Jackson, president of the Global Aging Institute, told Axios. "It’s also possible — but not certain — that health spans will continue to rise along with life spans, and that may take some pressure off."
China surpassed the U.S. for healthy life expectancy for the first time in 2016. Yun Sun, director of the China program at the Stimson Center, told Axios that one reason is that obesity and drug use are not as common in China.
Aspartame Still Hasn’t Been Proven Safe to Eat, Say Scientists
Too much sugar is bad for your health — but the world’s most popular alternative might not be any better.
For decades, experts have questioned the safety of artificial sweetener aspartame — also known as NutraSweet — with some studies concluding that the sugar substitute can cause a host of health problems, from brain damage to cancer.
To put the issue to rest, the European Food Safety Authority (EFSA) conducted a closed-door review of available aspartame studies in 2013 and found it to be safe — but according to new research, that’s only because they threw out all the studies claiming otherwise.
Consumer Reports finds potentially deadly bacteria in pre-washed greens
A new report out Friday reveals some leafy greens recently sold at supermarkets were contaminated with a potentially deadly bacteria. Consumer Reports says it tested nearly 284 samples of fresh greens like lettuce, spinach and kale and found six of those samples tainted with listeria.
Consumer Reports says the six contaminated samples included both pre-washed and unbagged greens sold at retailers in Connecticut, New Jersey, and New York in June, including Acme, Costco, Hannaford, and Whole Foods. All of the retailers stress that food safety is a top priority, and public health officials have not reported any illnesses or concerns following their own inspections.
Consumer Reports notes their study is not large enough to draw any conclusions about a specific brand or retailer, but rather is a "snapshot" intended to highlight that more needs to be done to ensure safety.
Climate change: 12 years to save the planet? Make that 18 months
Do you remember the good old days when we had "12 years to save the planet"?
Now it seems, there's a growing consensus that the next 18 months will be critical in dealing with the global heating crisis, among other environmental challenges.
Last year, the Intergovernmental Panel on Climate Change (IPCC) reported that to keep the rise in global temperatures below 1.5C this century, emissions of carbon dioxide would have to be cut by 45% by 2030.
But today, observers recognise that the decisive, political steps to enable the cuts in carbon to take place will have to happen before the end of next year.
The idea that 2020 is a firm deadline was eloquently addressed by one of the world's top climate scientists, speaking back in 2017.
Death rates increasing for U.S. adults aged 25 to 44: CDC
Death rates are on the rise for young and middle-aged U.S. adults, with white and black people experiencing higher mortality than Hispanic people, according to new research from the Centers for Disease Control and Prevention (CDC) published Tuesday.
Between 2012 and 2017, the rates for white and black people aged 25 to 44 increased 21% each for both groups, while Hispanic people of the same age range saw a 13% rise.
Sally Curtin, a statistician at the CDC’s National Center for Health Statistics and one of the report’s authors, said an uptick in suicides, homicides and drug overdoses contributed to the higher rates for the younger part of the group.

Research Shows High Prices Of Healthy Foods Contribute To Malnutrition Worldwide
First global examination of affordability of both healthy and unhealthy foods shows prices matter for diet and health outcomes
Poor diets are the now the leading risk factor for the global burden of disease, accounting for one-fifth of all deaths worldwide. While the causes of poor diets are complex, new research finds the affordability of more nutritious foods is an important factor.
A new study by researchers at the International Food Policy Research Institute (IFPRI) is the first to document that the affordability of both healthy and unhealthy foods varies significantly and systematically around the world. The study also suggests that these relative price differences help explain international differences in dietary patterns, child stunting and overweight prevalence among adults.
These Horrible Portion-Control Plates Are a Symptom of a Bigger Problem
Boys are hitting puberty earlier, partially due to rise in BMI, study suggests
Girls aren't alone in hitting puberty earlier -- boys are, too, according to a study published Monday in the medical journal JAMA Pediatrics. And boys' body mass index as children might play a role.
Researchers looked through school health records and assessed trends in height and growth for 4,090 boys born in Sweden from 1947 to 1996. Boys born later in that 50-year time period hit puberty sooner. For every decade born later, boys reached peak height velocity, or PHV -- the study's marker for puberty -- 1.5 months earlier.
The age at PHV became progressively younger for boys born later, dropping from about 14.2 years in 1947 to 13.7 years in 1996.
Yes, women like porn, too – we're all just trained to believe they don't
Cover up, men! You’re distracting women...
Shocking neuroscience news this week, as a rousing new study discovers women have sex drives. Researchers from the Max Planck Institute for Biological Cybernetics in Germany analyzed brain-imaging findings from a wide body of research and found that the “the neuronal response to visual sexual stimuli … is independent of biological sex”. In other words, women and men get just as horny when they look at erotic imagery. These revelations were published in the Proceedings of the National Academy of Sciences.
Teens are increasingly depressed, anxious, and suicidal. How can we help?
Suicide rates lately have been increasing in all age groups in America, in almost every state. But the epidemic of youth suicide is particularly stymying, even for experts who study it.
There are plenty of hypotheses about what’s driving it floating around. They include the changing way teens interact with each other in digital spaces, economic stress and fallout from the 2008 recession, increasing social isolation, suicide contagion, and the fact that teens can more easily look up suicide methods online.
Two other enormous public health issues of our time are at play too. Children of opioid users appear to be more at risk for suicide. Same goes for young people who live in a house with a gun.
But the bottom line is that no one really knows why. That doesn’t mean more suicides can’t be prevented, however.
