Cells control energy metabolism via hedgehog signalling pathway

Cancer, diabetes, and excess body weight have one thing in common: they alter cellular metabolism. Scientists from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and the Medical University of Vienna ...

Bouncing on Titan: How Huygens landed

(Phys.org)—ESA's Huygens probe bounced, slid and wobbled its way to rest in the 10 seconds after touching down on Saturn's moon, Titan, in January 2005, a new analysis reveals. The findings provide novel insight into the ...

Making and breaking heterochromatin

To fit the two-meter long DNA molecule into a cell nucleus that is only a few thousandths of a millimetre in size, long sections of the DNA must be strongly compacted. Epigenetic marks maintain these sections, known as heterochromatin. ...

Insecticide resistance caused by recombination of two genes

Larvae of the cotton bollworm (Helicoverpa armigera) are dreaded pests all over the world. They have a very wide host range: About 200 different plant species are known as potential food for the voracious insect. The herbivore ...

Fungi discovered to be source of methane

(Phys.org)—Some six years ago scientific textbooks had to be updated because of the surprising discovery made by the research group led by Frank Keppler that plants produce methane in an oxygen-rich environment. At that ...

Mystery of dark matter may be near to being deciphered

(Phys.org)—The universe is comprised of a large amount of invisible matter, dark matter. It fills the space between the galaxies and between the stars in the galaxies. Since the prediction of the existence of dark matter ...

Human evolution has become multi-colored

Thus far, a tiny finger bone and two back teeth in a cave in the Altai Mountains are the only known remains of the Denisovans – a humanoid that Max Planck researchers have identified solely through their genetic material. ...

Small droplets grow differently

(Phys.org)—Fine dew drops on spider webs, blades of grass, and even insects can lend them breathtaking beauty. And, examining them very closely, one recognises that the drops themselves form astonishingly regular and aesthetic ...
