Palaeontology: Girls and boys come out to play

The Economist - 23 Oct 2014 16:53
Palaeontology: Girls and boysTo have and to hold SEX is ubiquitous, but sexual intercourse is not. On dry land, it is more or less de rigueur. Sperm and eggs risk dessication otherwise. Mammals, birds and reptiles do it. Insects... do it. Even snails do, it--firing darts at each other as part of the preliminaries. But many creatures live in the oceans, and a lot of them simply broadcast eggs and sperm into the water and hope that these will meet. Even those marine animals that do come together to mate--bony fish, for example--often employ external fertilisation. That has led researchers to assume that copulation, in which a male's sperm are inserted into a female's reproductive tract, and fertilisation takes place therein, is a derivative rather than an original characteristic of the vertebrate line that leads from the...
No Proof That 'Brain Training'Many "brain-training" games may be marketed as a way to boost people's alertness and intelligence, but scientists are now warning that such claims are not based on actual science.
The flu virus is responsible for about 36,000 deaths in the U.S. every year, but the common killer hardly elicits the same panic as Ebola, a disease that has devastated parts of Guinea, Liberia and... Sierra Leone, but has killed just one person in the U.S.
Man Recovers From Ebola inOne man who contracted Ebola and even had further complications of the infection has now recovered after receiving routine intensive care at a hospital in Germany.

New microscope collectsOver the last decade, powerful new microscopes have dramatically sharpened biologists' focus on the molecules that animate and propel life. Now, a new imaging platform developed by Eric Betzig and... colleagues at the Howard Hughes Medical Institute's Janelia Research Campus offers another leap forward for light microscopy. The new technology collects high-resolution images rapidly and minimizes damage to cells, meaning it can image the three-dimensional activity of molecules, cells, and embryos in fine detail over longer periods than was previously possible.
