From car design to drug discovery, the failure to acknowledge sex differences can be costly and even lethal, argues Londa Schiebinger.
Archaeology: Ancient cheese found with mummies
Nature 507, 7490 (2014). doi:10.1038/507010a
The oldest known pieces of cheese have turned up in the tombs of an early Bronze Age cemetery in Xinjiang, China.Andrej Shevchenko at the Max Planck Institute of Molecular and Cell Biology and Genetics in Dresden, Germany, Changsui Wang at the University of Chinese
Cancer: How cancer skirts brain defences
Nature 507, 7490 (2014). doi:10.1038/507010b
Proteins that block cell death and help cells to integrate with blood vessels are crucial in the spread of cancer to the brain.Brain metastasis is often deadly, but most cancer cells that invade the brain die without establishing a tumour. To find ways in
Materials: Changing colour under pressure
Nature 507, 7490 (2014). doi:10.1038/507010c
Materials that change colour when pulled or squeezed could form the basis of display screens or sensors. But existing photonic gels, which change colour when deformed, cannot cover the entire rainbow or switch quickly.Now, Jianping Ge at East China Normal University in Shanghai and
Genetic engineering: Genes make bacteria magnetic
Nature 507, 7490 (2014). doi:10.1038/507010d
Researchers have transferred genes for the production of magnetic nanocrystals from one species of bacteria to another, a step towards making bacterial bioreactors that generate such particles.Dirk Schueler at Ludwig-Maximilians University in Munich, Germany, Youming Zhang at the Helmholtz Joint Institute at Shandong University
Microbiology: Stubborn microbe finds hiding spots
Nature 507, 7490 (2014). doi:10.1038/507011a
Salmonella bacteria can escape antibiotics and immune-system attack by hiding inside a host's immune cells.Roland Regoes and Wolf-Dietrich Hardt of the Swiss Federal Institute of Technology in Zurich and their colleagues infected mice with Salmonella enterica and then treated the animals with
Animal behaviour: Worms bond to reach new heights
Nature 507, 7490 (2014). doi:10.1038/507011b
To reach passing beetles, parasitic worms congregate into towers up to 30 times taller than an individual.Hans-Joachim Knölker at the Dresden University of Technology in Germany, Teymuras Kurzchalia at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, and their team
Materials: Waste glass finds diffuse use
Nature 507, 7490 (2014). doi:10.1038/507011c
A by-product of antiquated glass-making processes could find a new lease of life as an optical diffuser.Manufacturers now avoid producing crystals, called devitrite, in their soda–lime–silica glass because they degrade the material's optical qualities. But Haider Butt at the University of Birmingham, UK, and
Palaeontology: Algae dealt blow to ancient whales
Nature 507, 7490 (2014). doi:10.1038/507011d
The unearthing of more than 40 marine mammal fossils (pictured) at a site in Atacama, Chile, has revealed that they probably died en masse in four events due to toxic algae.Nicholas Pyenson of the Smithsonian Institution in Washington DC and his colleagues
Zoology: Pheromone turns on goat brains
Nature 507, 7490 (2014). doi:10.1038/507011e
Researchers have pinpointed a molecule produced by male goats that activates reproduction in females outside of their normal breeding season.Yukari Takeuchi at the University of Tokyo and her colleagues used a special cap to capture 18 different pheromone molecules emitted from the heads of

Books in brief
Nature 507, 7490 (2014). doi:10.1038/507037a
Marine biologist Stephen R. Palumbi and writer Anthony R. Palumbi survey an impressive catch of extreme oceanic species, from the oldest to the deepest-dwelling. They are inspired guides, weaving evolutionary and geological backstories into accounts of wonders such as the exquisite architecture of sharks' teeth.
