The bald facts about diet: to avoid hair loss, you need meat
"Eating a healthy, balanced diet and avoiding excessive stress, extreme diets and fast weight loss are vital in maintaining healthy hair growth," says Lisa Caddy, a certified trichologist with Philip Kingsley, a leading authority in hair and scalp health from London.
The irony: what many people think of as a healthy diet - that is, mainly consisting of fruit and vegetables, with minimal protein and calories - often doesn't include all the elements needed for optimum hair growth, Caddy says.
To function at their best, the cells in the hair and throughout the body need a balance of proteins, complex carbohydrates, iron, vitamins and minerals.
Meats, especially red meats, are particularly important because they're the richest sources of ferritin, a stored iron that helps the body produce hair cell protein.
Here's what happens to your body when you cut out dairy
Making any change to your diet, whether large or small, can be nerve-wracking. When your body has become so accustomed to consuming and digesting a product, it can be concerning to completely eliminate it. One product that more and more people seem to be cutting out is dairy.
Whether you want to cut out dairy for ethical reasons, because consuming it doesn't make your body feel great anymore, or because you've seen it have a positive impact on others — such as with celebrity Khloe Kardashian who credits the elimination of dairy for part of her weight loss— this could be a great choice for you. There's a lot you need to consider, however, before you make the leap, including how your body could react.
Here's what could happen to your body if you cut our dairy.
Gay men more likely to cheat than straight men, say psychologists
"In the gay life, fidelity is almost impossible. Since part of the compulsion of homosexuality seems to be a need on the part of the homophile to “absorb” masculinity from his sexual partners, he must be constantly on the lookout for [new partners]. Constantly the most successful homophile “marriages” are those where there is an agreement between the two to have affairs on the side while maintaining the semblance of permanence in their living arrangement. [p. 208]"
Gay life is most typical and works best when sexual contacts are impersonal and even anonymous. As a group the homosexuals I have known seem far more preoccupied with sex than heterosexuals are, and far more likely to think of a good sex life as many partners under many exciting circumstances.

Why Drinking Water All Day Long Is Not the Best Way to Stay Hydrated
Water is cheap and healthy. And drinking H2O is an effective way for most people to stay hydrated. The National Academy of Medicine recommends that adult women and men drink at least 91 and 125 ounces of water a day, respectively. (For context, one gallon is 128 fluid ounces.) But pounding large quantities of water morning, noon and night may not be the best or most efficient way to meet the body’s hydration requirements.
“If you’re drinking water and then, within two hours, your urine output is really high and [your urine] is clear, that means the water is not staying in well,” says David Nieman, a professor of public health at Appalachian State University and director of the Human Performance Lab at the North Carolina Research Campus. Nieman says plain water has a tendency to slip right through the human digestive system when not accompanied by food or nutrients. This is especially true when people drink large volumes of water on an empty stomach. “There’s no virtue to that kind of consumption,” he says.
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.
Deadly Virus Found In Florida, Causes Brain Swelling From Mosquito Bites
The latest U.S. healthcare news warns the rapid spread of a deadly mosquito-borne virus known as Eastern equine encephalitis (EEE) in Florida that causes brain-swelling.
According to reports, many sentinel chickens have tested positive for EEE.
The confirmed presence of the virus in Orange County’s sentinel chickens have raised “the risk of transmission to humans,” according to a statement by the county’s department of health.
Sentinels are fowls tested for the West Nile virus and EEE. Their blood samples may show the presence of the diseases but it is not necessary that they would suffer from the viruses.
The EEE virus spreading to humans via carriers like mosquitoes will lead to brain infection and swelling.
Maine Confirmed Its First Case of a Rare Tick-Borne Virus in Years. Here's What to Know About Powassan
Health officials have confirmed that an individual in Maine is sick with Powassan virus disease, marking the first time since 2017 that a person in the state has come down with the rare and serious tick-borne illness.
The Maine Center for Disease Control and Prevention announced Wednesday that a southern Maine resident was hospitalized for Powassan encephalitis—brain inflammation associated with the virus—after showing symptoms in late June. The announcement did not specify the individual’s current condition, but health officils doctors to stay vigilant about the potential spread of Powassan throughout the summer and early fall.
Here’s what to know about the tick-borne Powassan virus disease.
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.
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.
Cameron Boyce's death shines a light on fatal stigma
The death of Cameron Boyce, the talented Disney actor who according to his family died in his sleep following a seizure at the age of 20, resonates deeply with the experiences of so many other families who have lost their loved ones to Sudden Unexpected Death in Epilepsy (SUDEP). Boyce's family has said his fatal seizure was the result of epilepsy, and while Boyce's final cause of death has yet to be determined, his tragic loss is a reminder that every year, about 1 in 1,000 people with epilepsy suddenly die. Among those whose seizures are not controlled by medicine, the rate rockets to a stunning 1 in 150.
MILEY CYRUS WON’T HAVE CHILDREN BECAUSE ‘THE EARTH IS ANGRY’
The "Mother’s Daughter" singer said the planet has been depleted and that she will not have children “until I feel like my kid would live on an earth with fish in the water”.
“We’ve been doing the same thing to the earth that we do to women. We just take and take and expect it to keep producing. And it’s exhausted. It can’t produce,” the 26-year-old said. “We’re getting handed a piece-of-shit planet, and I refuse to hand that down to my child.
How rich people could help save the planet from climate change
Rich people don't just have bigger bank balances and more lavish lifestyles than the rest of us -- they also have bigger carbon footprints.
The more stuff you own, and the more you travel, the more fossils fuels are burned, and the more greenhouse gases are emitted into the atmosphere.
Jetting around, buying luxury goods, keeping mansions warm and driving supercars -- they all have a carbon footprint.
Oxfam has estimated that the average carbon footprint of someone in the world's richest 1% could be 175 times that of someone in the poorest 10%. Studies also show that the poor suffer the most from climate change.

But some argue that the wealthy can do the most to help fix the climate crisis. Here's how they could make a difference.
Now Fruit Juice Is Linked to a Higher Cancer Risk
Drinking soda doesn’t just threaten to make us fat, it could be linked to a higher risk of cancer, judging from a new study. But here’s the more surprising part: so could fruit juices.
Increased daily consumption of about 3.4 ounces of soda -- roughly a third of a can of Coke -- was associated with an 18% greater risk of some cancers in a study published in the British Medical Journal. The likelihood of breast tumors alone rose even more, by 22%. When people drank the same amount of unsweetened fruit juice, they were also more likely to develop cancer, the researchers found.
The research, part of a broader effort carried out in France to investigate links between nutrition and health, is one of the first to find a connection between sweet drinks and cancer. The findings may also taint the image of fruit juices, which are often perceived -- and promoted -- as healthy.
