Life Sciences and Chemistry

Articles and reports from the Life Sciences and chemistry area deal with applied and basic research into modern biology, chemistry and human medicine.

Valuable information can be found on a range of life sciences fields including bacteriology, biochemistry, bionics, bioinformatics, biophysics, biotechnology, genetics, geobotany, human biology, marine biology, microbiology, molecular biology, cellular biology, zoology, bioinorganic chemistry, microchemistry and environmental chemistry.

’Eau de dad’ woos women

Genes mean ladies like friends and partners that smell like their father.

Bachelors – ditch the Old Spice and don your prospective father-in-law’s clothes. Women prefer the scent of their dad, a study shows, and may choose their friends and partners accordingly.

Nervous new boyfriends can live or die by the nod of a date’s daunting dad. But Carole Ober and her team at the University of Chicago in Illinois have found a more fundamental fatherly influence: women prefe

Chimpanzee waste could shed light on the origins and spread of HIV.

Delving into droppings has given AIDS researchers a surprise. Far fewer chimpanzees than they had suspected have SIVcpz, the animal virus most like HIV.

The technique could shed much-needed light on the origins and evolution of the viruses that cause AIDS. “It’s a non-invasive means to study the wild relative of HIV in its natural environment,” says Beatrice Hahn, of the University of Alabama in Birmingham,

Life, as it was in the beginning?

A new type of Earth ecosystem could be found on other planets.

Scientists have found a community of microbes unlike anything else on Earth. Conditions in this ecosystem could mimic those on Earth when life began, and might exist elsewhere in today’s Solar System.

Home to the microbes is a hot spring 200 metres beneath the US state of Idaho. Their lives owe nothing to the Sun. They generate energy by combining hydrogen from rocks with carbon dioxide, releasing methane as a by

Uprooting and replanting the tree of life

A new theory on the evolution of ancient microbes is set to challenge widespread scientific views of early life on earth and could overturn previous interpretations of the huge bank of molecular taxonomic data that has been built up in recent years, according to research published today in the International Journal of Systematic and Evolutionary Microbiology.

“I`ve reinterpreted fossil records to show that eukaryotes, which includes plants, animals and fungi, are only half as old as previous

Mother Finch Controls Baby’s Sex to Increase Survival Odds

Most mothers-to-be must simply hope for healthy offspring. But female house finches tip the odds in their babies’ favor by pre-determining their gender, a new study suggests. According to a report published in the current issue of the journal Science, enterprising mother house finches adjust the sex and growth of their offspring to account for the order in which the eggs are laid, thereby reducing the mortality of their sons and daughters by 10 to 20 percent.

Introducing the biology of the future: Researchers at CellZome AG and EMBL publish record-breaking analysis of a cell’s proteome

Scientists are calling it “biology of the next generation,” and a major step towards transforming information from genome projects into applications such as the discovery of new drugs. Today researchers from Heidelberg have announced the completion of a large-scale study of the “molecular machines” formed by nearly two thousand proteins in a living cell.

In a paper published in the current edition of Nature, a team of scientists from the biotechnology start-up company CellZome and the Europe
