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.
