Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
Did french fries taste better when they were cooked in fat? How about Coca-Cola when it was made with cane sugar or Fritos when they were salty?People will insist they can tell the difference and they probably can, but sales show that different is not worse. Today, adults are nostalgic about the stuff that older people say is no good.What about the taste of coffee? It is entirely subjective. Dark roast or light, Arabica or Robusta, you like what you like. What if what you like changes?A new paper seeks to sound the climate change around using coffee growing conditions.
A tipping point in climate computer estimates is a threshold where large and perhaps irreversible changes occur. Some estimates are silly, 20 foot ocean rises, etc., but without data from recent times it is hard to make models more reliable. There was a period of high warming nearly 1,100 years ago and in 10,000 B.C. we were still in an ice age, but with only accurate temperature readings for the last 40 years, and formal observation at all only done for the last 150 years, the only way for climate models of the future to be calibrated is to 'predict the past.'
A research team is working to better define how the finger interacts with a device to create technology that goes beyond sensing and reacting to touch - they want the ability to mimic the feeling of physical objects. Like virtual shopping experience that would let the user feel the texture of materials before purchasing them. And that's actually better for us in many ways.
Even if insurance and household incomes are similar, white people are more likely than people of color to be sent home after surgery rather than to a skilled nursing facility. People of color are also more likely to stay in long-term care or get care at home, according to results presented at the ANESTHESIOLOGY 2021 annual meeting.The reason, the authors believe, it is that people of color are more likely to have severe diabetes and high blood pressure, which can impact recovery.
It used to be that allergies were somewhat rare but if you go to an allergist today, you are almost certain to be declared allergic, or at least sensitive, to something. How much of that is actual biological change versus how much is that the country that purchases 85% of the world's prescription medication loves to get medical diagnoses is unclear.Now the European Academy of Allergy and Clinical Immunology believes that nearly half of the population of the EU have allergies to something. A survey of Americans in 2020 estimated that approximately 30 percent of Americans of all ages have allergies. Since they are self-reported surveys rather than dianoses, what is unclear is how many of those are people claiming issues like gluten sensitivity.
Though it is common to see environmental videos of birds caught in plastic, less well known is that, like cats, seabirds love to eat it.Paracelsus famously noted that the dose makes the poison but in the 1990s some activist scientists began claiming that any dose is a poison, so even if birds excrete the plastic, chemicals can "bioaccumulate" and cause harm.
Telescopes and inference told scientists that the asteroid Bennu was covered in large swaths of fine regolith, smaller than a few centimeters. What they found when OSIRIS-REx arrived at Bennu was something else: A surface covered in boulders. The surprise lack of fine regolith became even more interesting when mission scientists observed evidence of processes capable of grinding boulders into fine regolith. Yet they had not.
Pancreatic cancer tends to develop from chronic inflammation that happens when a mutation has caused digestive enzymes to digest the pancreas itself.What if we could go 'back in time' and reverse that process?Purdue University Professor Bumsoo Han and his team built is a lifelike reproduction of a pancreatic structure called the acinus, which produces and secretes those digestive enzymes into the small intestine. The goal is reprogram the cancerous acinar cells that produce those enzymes, and perhaps completely reset the pancreas.
In 2019, three free-ranging cheetahs in the Namib Desert died within 24 hours of each other. Scholars set out to determine why.On October 5th 2019, the carcass of a GPS-collared cheetah in the Namib desert was found dead from the air. After they went in on foot to investigate, two other cheetahs were also found dead. The GPS data showed they had all died within a short period of each other so the team then identified a cluster of GPS locations approximately two kilometers away from the location where they were found dead.
For a pilot study, a team examined blood samples from 50 patients and 16 healthy subjects. Using atomic force microscopy technology, they analyzed the surface of around 1000 red blood cells per person without knowing anything about their state of health. They were able to detect the presence of suspicious proteins, beta-amyloid peptides and tau proteins associated with the neurodegenerative disease commonly called dementia. but also to determine their variable shape and form as well as their amounts.
Exercise is healthy. That is common knowledge. But just how rigorous should that exercise be in order to really impact a person’s fitness level? And, if you sit all day at a desk, but still manage to get out and exercise, does that negate your six, seven, or eight hours of sedentary behavior? These were the sort of questions Matthew Nayor and his team at Boston University School of Medicine set out to answer in the largest study to date aimed at understanding the relationship between regular physical activity and a person’s physical fitness.
The rapid development of effective mRNA vaccines for COVID-19 has led some observers to suggest that mRNA will push other types of vaccines out of the market completely in the near future. But is that desirable? Is it even possible?
