Spider blood found in 20 million year old fossil

...g up a tree when it was struck head-on by a sudden strong flow of resin. The spider then became engulfed in the resin and died. He argues that the shape and position of the blood droplets reveals which direction the spider was travelling in. It also reveals which of the spider's legs broke first. David di...

Space matters: Estimating species diversity in the fossil record

...nce the number of species, Barnosky et al. found a strong species-area effect. These results, they argue, suggest that many fluctuations in diversity seen in fossil analyses actually arise from the species-area effect and are not actually the result of true changes in the distribution of species. Given the...

A novel virus for croup

...se where no other virus could be detected. Here, a strong relationship with the clinical symptoms associated with croup was apparent: 43% of the HCoV-NL63 positive patients with high HCoV-NL63 load and absence of co-infection had croup, compared with 6% of HCoV-NL63 negative patients. Previous studies have ...

Biased reporting found in cancer prognostic studies

... of these details may have helped to fabricate the strong prognostic factor/cancer association in these studies, according to the authors. "These biases may create a spurious knowledge base of cancer predictors that may be of no use and may be potentially harmful," conclude the authors. However, they cauti...

Study casts doubt on 'Snowball Earth' theory

...reviously unexamined rock formations has turned up strong evidence on the "Slushball Earth" side of a decades-long scientific argument. The study appears in the Sept. 29 Science Express.
