We show that the shape of the birth canal varies among human populations, with important implications for obstetric practice in multi-ethnic societies. These differences reflect genetic variation among populations and ancient global migrations.

The relationship between metabolism and hypertension should not be underestimated! There is a new way of treating hypertension caused by dietary salt: increasing the intake of a water-soluble small molecule called beta-hydroxybutyrate (βOHB).

Using a trick inspired by noise-cancellation headphones, we have been able to control the motion of a millimeter-sized drum at the “quantum level”, even though it is big enough to see with our bare eyes.

Semiaquatic fur seals have little or no REM sleep when in water for 2 weeks. Upon coming back to the land-life they return to have normally about 80 min of REM sleep a day. Such a unique ability to turn REM sleep on and off leads us to better understand its biological role.

The taste of a fruit is largely determined by its sugar composition. Understanding the mechanisms responsible for the accumulation of different sugars will enable us to select fruits to increase their consumption. A model of sugar metabolism allowed the identification of a candidate mechanism to explain the difference in sugar composition observed in commercial and wild peach fruits.

The current study highlights the effect of a meningococcal vaccine on gonorrhoea, a disease caused by a superbug that has evaded vaccine development for over 100 years.
