Women who work during pregnancy are almost five times as likely to develop pre-eclampsia, concludes research in the Journal of Epidemiology and Community Health.

In pre-eclampsia abnormally high blood pressure, blood poisoning, and swelling develop. Pre-eclampsia can be dangerous for both mother and child.

The blood pressure of 933 women in their early to late 20s was monitored over 24 hours while they went about their daily routines. The women were all between 18 and 24 weeks of pr

Optimism about the success of heart and lung transplants at the start of the 1990s is not supported by the evidence, shows an audit of the procedure, published in Heart.

Transplants continue to be hampered by the high death rates after surgery and a shortage of suitable donors, finds the study. Almost half of those waiting for a lung transplant will not receive one, and at least a quarter will die within two years of being listed.

All nine UK units performing heart, lung, or heart

Brass instrument makers could soon be using the latest technology to refine the manufacturing of trumpets and cornets. An improved way of taking internal measurements of musical instruments, published today in the Institute of Physics journal, Measurement Science and Technology, has been developed by scientists at the University of Edinburgh, the Open University and Smith-Watkins Brass.

In a trumpet or cornet the musical qualities of the instrument, for example the tone, response and intonat

One lump of rock is revealed as two in the distant Kuiper belt.

The stand-offish dance of two asteroids at the outer reaches of the Solar System is captivating astronomers. The two rocky objects, discovered locked in mutual orbit, could tell us about the properties of the far-flung Kuiper belt.

Christian Veillet and his team 1 studied an object called 1998 WW31 in the Kuiper belt, a sparsely populated region of space beyond the orbit of Neptune. The object w

Two cricket-like creatures establish new insect group.

The first new order of insects to be discovered for more than 80 years has emerged from the mountains of Namibia. The order’s first official members are two creatures about 2 cm long that look a bit like a cross between a cricket and a stick insect 1 .

The group, called Mantophasmatodea, joins the other 30 or so insect orders such as beetles, flies and termites. “If it was in mammals it’d be like

Between now and Saturday, 20 April, you can follow via the Internet the progress of the new-found Comet SOHO-422. Usually, comets seen by the SOHO spacecraft quickly burn up in the Sun’s hot atmosphere. This one won’t, so there is still time to monitor its progress.

Like most of the hundreds of comets found with the ESA-NASA sun-watching spacecraft, SOHO-422 was first noticed by an amateur astronomer. Pictures from SOHO are made available, freely and rapidly, on the Internet. Peop
