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.

Newfound Brain/Lymph System Link May Lead to Better Health

Researchers in Finland confirmed a suspected link between the brain and lymphatic system using new imaging technology to answer the question of brain fluid draining into the lymph system without a direct link between the two. The research team at the University of Helsinki said the discovery could be significant for the way brain diseases and disorders are handled.

Humans’ Built-in GPS is our 3-D Sense of Smell

Humans’ Built-in GPS is our 3-D Sense of Smell

Like homing pigeons, humans have a nose for navigation because our brains are wired to convert smells into spatial information, new research from the University of California, Berkeley, shows. While humans may lack the scent-tracking sophistication of, say, a search-and-rescue dog, we can sniff our way, blindfolded, toward a location whose scent we’ve smelled only once before, according to the UC Berkeley study published today (June 17) in the journal PLOS ONE.

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.

Darwin Was Wrong: Compassion Helped Fuel Human Evolution – NOT Survival of the Fittest

A new study of early humans has challenged one of the main tenets of Darwin’s evolutionary theory, the idea of the survival of the fittest, by suggesting compassion and the ability to accommodate “defective” members of the community actually played a significant role in how humans developed.

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.

Strange Behavior Of Quantum Particles May Indicate The Existence Of Other Parallel Universes

Strange Behavior Of Quantum Particles May Indicate The Existence Of Other Parallel Universes

In his theory, Poirier postulates that small particles from many worlds seep through to interact with our own, and their interaction accounts for the strange phenomena of quantum mechanics. Such phenomena include particles that seem to be in more than one place at a time, or to communicate with each other over great distances without explanations. There is no fuzziness in his theory. Particles do occupy well-defined positions in any given world. However, these positions vary from world to world, explaining why they appear to be in several places at once. Likewise, quantum communication of faraway particles – something Albert Einstein called “spooky action at a distance” – is actually due to interaction of nearby worlds.

New Evidence Emerges on the Origins of Life

New Evidence Emerges on the Origins of Life

In the beginning, there were simple chemicals. And they produced amino acids that eventually became the proteins necessary to create single cells. And the single cells became plants and animals. Recent research is revealing how the primordial soup created the amino acid building blocks, and there is widespread scientific consensus on the evolution from the first cell into plants and animals. But it’s still a mystery how the building blocks were first assembled into the proteins that formed the machinery of all cells. Now, two long-time University of North Carolina scientists – Richard Wolfenden, PhD, and Charles Carter, PhD – have shed new light on the transition from building blocks into life some 4 billion years ago.

Should Flibanserin (the New “Female Viagra”) Be Approved by the FDA?

As women age, their sex drive can decrease significantly. Have doctors found a pill that can relight a woman’s sexual desire? On 3 and 4 June, the US Food and Drugs Administration (FDA) will convene an advisory panel to recommend whether Flibanserin – touted as the “female Viagra” – should be approved for use in patients. The question is divisive, however – with strong arguments for and against.
