The Amazon Rainforest: Was it ‘Man Made’ by Our Ancestors?

It is often held aloft by environmental campaign groups as an example of one of the last remaining regions of unspoiled habitat left in the world. But instead of being a pristine rainforest untouched by human hands, the Amazon appears to have been profoundly shaped by mankind. An international team of researchers have published evidence that suggests the Amazon was once home to millions of people who lived and farmed in the area now covered by trees. The scientists claim the Amazon basin was a major centre of crop domestication that saw at least 83 native species being cultivated to some degree.

Women’s Brains May Be the Most Vulnerable to Alzheimer’s

Women’s Brains May Be the Most Vulnerable to Alzheimer’s

Women’s brains might be more vulnerable to the degenerative effects of Alzheimer’s disease than men’s, causing them to decline in memory and cognitive function twice as fast, according to new research that could explain why women make up two-thirds of all diagnosed Alzheimer’s cases in the US.

The finding was presented this week at the 2015 Alzheimer’s Association International Conference (AAIC) in Washington, DC, with the team also noting that women tend to decline more dramatically than men in cognition, function, and brain size after they’ve been in surgery or under general anaesthesia.

Brain Area Found That May Make Humans Unique

Neuroscientists have identified an area of the brain that might give the human mind its unique abilities, including language. The area lit up in human, but not monkey, brains when they were presented with different types of abstract information.

We’re Not All Aging at the Same Rate, Researchers Say

We’re Not All Aging at the Same Rate, Researchers Say

How long we’ve been on the planet isn’t necessarily reflected in our biological age, an international team of scientists has found. According to a new study, some of us are ageing faster than others, and there can be significant variations in how run-down our bodies become as we develop as adults. The team looked at physiological markers in almost 1,000 38-year-olds, and while most had biological ages that roughly matched the number of birthdays they’d celebrated, some of the test subjects had bodies that appeared to be much younger or older, based on a series of medical examinations.

Watch The Awesome Chemistry of Fireworks (Video)

Gunpowder is the key ingredient, but as adjunct professor of chemistry John Conkling from Washington College in the US explains in this video, without chemistry, you wouldn’t have burning mixtures and without these you simply can’t have fireworks.

This Just in: Emotional & Rational Brains ‘physically different’

This Just in: Emotional & Rational Brains ‘physically different’

Researchers at Monash University have found physical differences in the brains of people who respond emotionally to others’ feelings, compared to those who respond more rationally, in a study published in the journal NeuroImage. The work, led by Robert Eres from the University’s School of Psychological Sciences, pinpointed correlations between grey matter density and cognitive and affective empathy. The study looked at whether people who have more brain cells in certain areas of the brain are better at different types of empathy.

Plants Know When They Are Being Eaten (and Freak Out)

If you didn’t already recognize plants as sentient beings, maybe this study from the University of Missouri will change your mind: Researchers at the University of Missouri, in a collaboration that brings together audio and chemical analysis, have determined that plants respond to the sounds that caterpillars make when eating plants and that the plants respond with more defenses.

First Evidence That Parents’ Life Choices May Change Kid’s DNA

First Evidence That Parents’ Life Choices May Change Kid’s DNA

For the first time, scientists have discovered a mechanism in humans that could explain how your lifestyle choices may impact your children and grandchildren’s genes. Mounting evidence suggests that environmental factors such as smoking, diet and stress, can leave their mark on the genes of your children and grandchildren. For example, girls born to Dutch women who were pregnant during a long famine at the end of the second world war had twice the usual risk of developing schizophrenia. Likewise, male mice that experience early life stress give rise to two generations of offspring that have increased depression and anxiety, despite being raised in a caring environment. This has puzzled many geneticists, as genetic information contained in sperm and eggs is not supposed to be affected by the environment, a principle called the August Weismann barrier.

Tiny Songbird Discovered to Fly 1,700 Miles Non-Stop Over Open Ocean

For more than 50 years, scientists had clues suggesting that a tiny songbird known as the blackpoll warbler fly’s nonstop over the Atlantic Ocean, but proof was hard to come by. Now, an international team of biologists report “irrefutable evidence” that the birds complete a nonstop flight ranging from about 1,410 to 1,721 miles (2,270 to 2,770 km) in just two to three days.

The Fourth Phase of Water

The reason this fourth phase of water is called the exclusion zone or EZ is because the first thing Dr. Pollack’s team discovered is that it profoundly excludes things. Even small molecules are excluded from EZ water. Surprisingly, EZ water appears in great abundance, including inside most of your cells. Even your extra-cellular tissues are filled with this kind of water.

Reinventing the Wheel, Just So the Greedy Can Patent & Profit from it: Focus on Alzheimer’s

I have recently read 2 articles, and received a plea for pledges, regarding Alzheimers. So, I began to reflect upon how, and question why, in the quest to blaze new trails on which to diagnose or fight a disease, our scientific and research programs often do not look at the tools around them and fashion those tools to do the job just as well.

Cancer Develops from Fungal Infections, like Candida

There are very few common threads among experts on what causes cancer, aside from obvious lifestyle choices like smoking and alcohol. However, to think cancer is largely caused by one thing is a bit too simplistic…or is it? Turns out, it may not be that complicated. A simple fungal infection can cause cancer…Candida.
