But the story of water gets a lot more scientifically interesting the deeper you go. Water actually exists in two different forms, called isomers, at the molecular level.
They have almost identical physical properties, you can't tell the difference, but chemists can tell them apart by the relative orientation of the nuclear spins of the two hydrogen atoms. They are called ortho- or para-water depending on whether the spins are aligned in the same or opposite direction.
Marine litter is a big deal thanks to environmental publicity but it is highly exaggerated - think mercury in salmon, alar on apples, floating barges of garbage, estrogen in drinking water and more to get an idea of how these issues get magnified.
Sub-Saharan Africa has around 80 million people infected with hepatitis B, a liver infection caused by the hepatitis B virus, but it infects around 250 million people worldwide. It can be a mild illness lasting a few weeks or a serious, lifelong condition. It is transmitted through blood and bodily fluids.
An accurate diagnostic score that consists of inexpensive blood tests costing around $20 could help diagnose thousands of patients with hepatitis B in need of treatment in some of Africa's poorest regions, far more affordable than the $100-500 for current tests.
For do-gooders, the ends justify the means. Do-gooders believe they are saving the world, therefore any tactic is completely defensible. In Santa Barbara, selling a drink with a plastic straw could result in a $1,000 fine and six months in jail.
Cancer Patients Who Use Complementary Medicine (Refuse Conventional) Twice As Likely To Die, Says Study
Complementary medicine (CM) ranges from authentic stress relieving massage and well-meaning, but expensive placebo to outright spurious healing claims. Researchers decided to study its impact on patients with curable cancers.
For women the risk is even higher, not just of cancer but also leukemia and cancers of the stomach, mouth and kidney. Men, however, had less risk for liver cancer. If none of that makes sense, you see the flaws in replacing science with epidemiological statistics.
Paracelsus famously noted that the dose makes the poison.
Medicaid is a taxpayer-funded program that provides free or low-cost health coverage to low-income people, the elderly, and people with disabilities. As many states are considering work requirements for Medicaid eligibility, the authors of a new paper believe Medicaid expansion is acting as an employment incentive for people with disabilities.
Evolution has an explanation for that. But like a lot of things in evolution, it may seem puzzling.
It shouldn't make sense, since dying young or becoming infertile due to infection means organisms will be unable to reproduce, but many species may have evolved to prioritize growth over immunity while maturing. And that complexity may be why immunity varies with age in different species.
While aspirin has been shown to be effective in reducing the risk of cardiovascular events, there have previously been no dosage recommendations tailored to a person's weight. But a new study indicates that a weight needs to be considered to improve helpful outcomes and prevent any harmful effects from occurring.
And that even people who didn't want to stop smoking have eventually quit because they found vaping more enjoyable. E-cigarettes contain nicotine, which is the addictive component of cigarettes also, but it's toxic chemicals in smoke that cause the harms of smoking. That is why e-cigarettes have caught on as an aid to help people quit smoking for good, whereas patches and gums are only effective for about 10 percent.
