Natural evolution has given us opposable thumbs, the ability to walk fully upright and brains that can reason. Now, scientists are poised to revolutionise fields from drug discovery to goods manufacturing by further harnessing evolution’s power in the laboratory.
ATM and ATR Form Separate Synaptic Vesicle Patterns
25 Jan 2018
In a recent study, an interdisciplinary team of scientists from The Hong Kong University of Science and Technology (HKUST) and The Chinese University of Hong Kong (CUHK) discovered that two large protein kinases, ATM and ATR, cooperate to help establish the go/stop balance.
Scientists culture human placenta stem cells for first time
24 Jan 2018
Scientists have derived and grown trophoblast stem cells for the first time, which will lead to better understanding of the human placenta.

Young Masu salmon, the host of Margaritifera laevis. The circled inset shows the gill of a Masu salmon infected with parasites. The white dots are larvae of the freshwater mussel.
22 Nov 2017
Large, physically strong Masu salmon disperse farther when infected with parasites, potentially escaping from further infections at the contaminated site but ironically resulting in the greater expansion of the parasite, according to Hokkaido University researchers.
Twisted sex allows mirror-image snails to mate face-to-face, research finds
21 Nov 2017
According to a recent study, differently-coiled types of Japanese land snails should in fact be considered a single species.
