Can altering the amount or rate of fluid injection and production in an oil and gas field or carbon storage site affect induced earthquakes in that field? Researchers have developed a technique that allows them to speed up or slow down human heart cells growing in a dish on command -- simply by shining a light on them and varying its intensity.
Carbon-based rocks, such as bitumen and tephra, can also be dated in this manner.
Carbon dating is most effective on material that predates the 1940s; this is due to above-ground nuclear tests increasing the amount of carbon-14 in the environment.
The study finds that the available budget is on the low ...
Hunting with lead shot is highly restricted or entirely banned in many countries due to the danger of poisoning birds and environment.
This inconsistent amount of carbon-14 renders the test less accurate but opens up testing possibilities not available for older samples.
