Being a giant in a country like New Zealand, well known for giant birds, is common. Moa dominated avifaunas but giant geese and adzebills shared the forest floor, while a giant eagle ruled the skies. But a giant extinct parrot? That is special.
The products of these keratin genes assemble to form the girders of the cytoskeleton in skin cells, called keratinocytes, that maintain a tight barrier between the body and the outside world.
Mental Health Disorders Are Not Like Measles, Which Makes It Difficult To View Them Using A Medical Lens
With two recent mass homicides, one by someone who endorsed "white supremacist" views and one that supported "Antifa" violence, the search is on for commonality between two people in opposition to each other in many ways. One commonality is skin color but there is no biological hypothesis for how melanin might increase violence. There certainly are not a lot of women doing these shootings so the chromosome correlation is one of the questions that needs to be asked.
However, a history of mental illness is common in almost all cases of mass violence.
In a small pilot study consume who consumed a natural dietary supplement called nicotinomide riboside (NR) daily showed signs of mimicking caloric restriction, which in mice has been linked to health benefits.
Caloric restriction is a starvation diet. When lower level organisms such as fruit flies, roundworms, rodents are raised on such a diet from birth, slashing of caloric intake by about a third has health benefits and, in some cases, extended lifespan. No humans have done that, it would be a human rights violation to wean a baby on a starvation diet, and claims about benefits in adults who took it up have too many confounders to be anything more than anecdotes.
Though the pancreas is an organ with little exposure to sex hormones, one form of pancreatic cancer affects specifically women, often young.
How is this possible, even though the pancreas ? This pancreatic cancer, known as "mucinous cyst", has strange similarities with another mucinous cancer, affecting the ovaries.
A new paper has a plausible answer. Both tumors originate from embryonic germ cells. While still undifferentiated, these cells migrate to the reproductive organs. On their way, some can mistakenly stop in other organs, bringing a risk of tumor that may occur 30 years later.
In developed countries, air quality is now great. So great that true smog (PM10 - particulate matter 10 microns in diameter) is basically going extinct in countries like America so epidemiologists and demographers have taken to promoting concern about particles so small they can only be detected with an electron microscope (such as PM2.5).
While claims of increased mortality due to PM2.5 have fallen flat, asthma still exists and it is well-known that asthmatics have shorter lifespans.(1) A new paper speculates that as many as 170 cases of asthma per 100,000 kids each year could be caused by traffic pollution, and specifically Nitrogen dioxide (NO2), which is really common at trace levels everywhere.
Oxidative stress plays a major role in the pathogenesis of both types of diabetes mellitus and cardiovascular diseases including hypertension. The low levels of antioxidants accompanied by raised levels of markers of free radical damage play a major role in delaying wound healing.
Rich Or Poor, Scammers Don't Cheat Because They Need The Money — They Cheat Because They're Cheaters
Why do people cheat?
When we hear that a poor person scammed others out of money, we may attribute this behavior to their poverty, rationalizing that the person violated ethics and the law because they needed the money.
Ingenious Responses To Rising Seas In Netherlands, Florida And Bangladesh - And How High Will The Sea Rise?
2019 Greenland Melt Not Likely To Beat 2012 Record - 0.5 Mm Sea Rise Ice Melt Is Dramatic, But Glacier Flow Is Long Term Issue
Short summary. The 0.5 mm sea level rise due to ice melting in July is dramatic but you need to compare it with the rest of the year. July is usually the top month for ice loss. In the winter the Greenland ice sheet gains ice through snowfall, so you need to look at the balance between losses and gains.
Also you need to compare it with previous years. It’s actually not quite enough of a melt so far to beat the 2012 record. The Arctic sea ice minimum this year is also not expected to be as low as the 2012 minimum. .
This is nothing to be scared of. Just an unsurprising increased melt, after a previous year when there was so much snow that Greenland actually gained ice due to heavy winter snowfall in 2017–8
Around the world thousands of people are on organ donor waiting lists. While some of those people will receive the organ transplants they need in time, the sad reality is that many will die waiting. But controversial new research may provide a way to address this crisis.
Japan has recently overturned its ban on the creation of human-animal hybrids, or “chimeras”, and approved a request by researchers from the University of Tokyo to create a human-mouse hybrid.
There is a reason that fossil fuels have stuck around for so long. No longer do they have terrific energy density in the form of gasoline but they make up many useful products. But many of those products can be difficult to recycle.
A new wood membrane takes a page out of the book of trees instead. In a limited sense, the intricate system of water circulating in a tree can filter it and a team of researchers have figured out how to use a thin slice of wood as a membrane through which water vapor can evaporate, leaving behind salt or other contaminants.
Whether you realize it or not, there’s a good chance that you are being exposed to bisphenol F (BPF). There’s even a fair chance that you are highly exposed. If so, should you be concerned and what should you do about it?
The high crests on their molar teeth are at risk of damage if they eat hard objects, such as nuts encased in a woody shell, but they do it anyway. And an anthropology paper seems surprised a primate might engage in behavior that is not a force of evolution.
Science has been doing something right in the last few years. That number is up by almost half, to 35 percent.(2)
Telepathic communication might be one step closer to reality thanks to new research from the University of Washington. A team created a method that allows three people to work together to solve a problem using only their minds.
In BrainNet, three people play a Tetris-like game using a brain-to-brain interface. This is the first demonstration of two things: a brain-to-brain network of more than two people, and a person being able to both receive and send information to others using only their brain. The team published its results in Scientific Reports after being posted on arXiv last year.
Fake News: Blame Partisan Media, Blame Social Media, But It's A Monster We All Created, And It's Worldwide
The term "fake news" has been popularized by President Donald Trump in recent years, and while its meaning has been hotly debated, the spreading of false information to fulfill a political agenda is far from a new concept. It's not just an American thing.
Agricultural areas cover 174 million hectares, 40 percent of the EU, yet despite what may be the world's most fertile land, Europe still accounts for 85 percent of the world's agricultural subsidies. Their products are too expensive to sell elsewhere without them.
