Is there an electronic component that can change its resistance based on the current that flowed trough it? A bit like air ionization just more permanently.

Basically satisfying the following equation: R(q) = C * sum(q) where R is the resistance, C is an arbitrary constant and q is the charge that traveled trough the device with a negative and a positive direction.

If an individual has 1 or more long bones amputated, is the body put under stress directly in effect of loosing a percentage of the site of blood cell production?

Would they be deficient in blood cells, or would the rate of hematopoiesis increase in the remaining bone marrow in order to compensate?

If humans went extinct, could we come back in a billion years in our exact current form?

Prisms are able to split light based on their wavelength, so what exactly causes the different wavelengths to be split?

Can serum sickness be caused by the injected antibodies?

Posted: 07 Apr 2022 03:37 PM PDT

Maybe a dumb question. Serum sickness as I've seen it defined is due to an immune response against some proteins within an antiserum. Is it possible for an injected foreign antibody to itself be recognized as an antigen?

Evidence of natural disasters?

Science people How do people know about natural disasters in the past, such as tsunamis a 100,000 years ago?
