Scientists know very little about the matter that makes up the galaxies in the Universe. About 20% of the matter in galaxies is visible or baryonic: subatomic particles like protons, neutrons and electrons. The other 80%, referred to as “dark matter”, remains mysterious and unseen.
In fact, it may not exist at all. “Dark matter” is just a hypothesis. Physicists and astronomers may be chasing a phantom – but that doesn’t stop us from looking. Why? Because if dark matter isn’t real, then the behaviour of the stars, planets and galaxies makes little sense.
The online posting, sending or sharing of hurtful content is like being trapped in a small town, except possibly the whole world sees it. So why would someone do it to themselves?
That's the puzzle of digital self-harm. Like older forms of self-harm (cutting, burning, hitting oneself), there is worry it will lead suicidal ideation and attempts, but since peers assume a third-party is the culprit, the dysphoric or abnormal reasons to post cruel, embarrassing or threatening content about themselves is compounded.
Not all that much to do with Hank’s recent blog about the Galileo document that isn’t, but a note about how Einstein could be somewhat “pig-headed”, similar misunderstandings and new developments in contemporary fundamental physics.
Across the Roman Empire, funerary rituals were conducted to ensure the protection of deities and the memory of the deceased. They were required by law.
Alternative Medicine Claims Another Victim - This Time Lori McClintock, Wife of U.S. Rep. Tom McClintock
Such deaths are considered accidental but if you wouldn't drink and drive on the windy roads of the Pacific Coast Highway, you shouldn't believe in folk medicine, traditional medicine, alternative medicine, complementary medicine, integrative medicine, or whatever else naturopaths and supplement charlatans are calling their dangerous money-making schemes these days.

Many of us enjoy a drink at the end of a stressful day. But for some, this is less of a discretionary treat and more of a nightly must-have.
While alcohol reduction campaigns ask us to check our relationship with alcohol, emphasising the role it can play in causing violence and disease, our research has found many Australian women view alcohol in a different way. Many don’t see alcohol as only a bad thing and have complex reasons for their relationships with alcohol.
We conducted 50 interviews with midlife women (45–64 years of age) from different social classes living in South Australia. All women had a relationship with alcohol but the nature of the relationship was really different according to their social class.
A launch window – the period during which a rocket must be launched to reach its destination – opens on August 29 for the first flight to the Moon since 1972 by a spacecraft designed to carry humans there. If all goes well, the Artemis project will be on track to meet its goal of putting humans back on the Moon in 2025.

Unlike databases of where people live such as companies like Ancestry.com uses to claim 'you are 12 percent Irish', biology is not a marketing gimmick. Once the science is settled, social fields like anthropology and other exploratory studies can fill in some gaps.
A new exploratory paper assessed the facial structure of prehistoric skulls, hoping to support the hypothesis that a lot of Neanderthal-Modern interbreeding took place in the Near East – the region ranging from North Africa to Iraq.

Their second introduction to reality is charging. If you are sleeping, and can sleep well knowing your electric car charging is equivalent load to an entire extra house on the grid, long charging times are fine, but it makes long trips a source of anxiety for most.
Mitochondria remain important throughout our lives. People with higher mitochondria function age 'better.'
Yet how mitochondrial defects lead to disease and aging has not been well understood. A paper published today in Aging Cell links mitochondrial dysfunction to the shortening of telomeres, specialized DNA sequences that act as caps that stabilize the ends of chromosomes, and premature aging.
