While it's only an estimate and relies on lots of assumptions, it's a good reminder that the fossil record only captures a tiny fraction of ancient life. The same team of researcherspurportsthat for every 80 million ad...

The defining feature of modern-day plant roots is the meristem—a self-renewing structure that is covered by a cap at its apex. Root meristems are hard to spot in the fragmentary fossil record, which can make it challenging to unearth the evolutionary origin of roots. The authors found evid...

Most importantly, they have been called the new oil because: (1) 'data powers today's most profitable corporations, just like fossil fuels energized those of the past' (Matsakis 2019) and (2) this means these qualities can be financialised. The amount of data on individuals that are now...
Bullet-fast moon rocks carved 2 lunar gorges deeper than the Grand Canyon Scientists discover black holes spinning unexpectedly fast: 'You’re essentially looking at its fossil record' The moon will cover the Seven Sisters of the Pleiades this week. Here's how to see itMORE...
indeed allow bacteria to break these items down into small particles at a far faster rate than normal (5 years versus over 100 years), the resulting particles are still fossil-fuel based environmental contaminants. One might actually argue that this process is more deleterious to the environment....

Opinion polls from Gaza and the West Bank, conducted last week show that students and professionals are more likely than the unemployed or...
