How genome doubling helps cancer develop
How genome doubling helps cancer develop
Researchers at EPFL and UNIL have uncovered a new way in which cancer can develop: whole genome doubling (WGD) changes the way DNA is organized in the 3D space, leading to the activation of oncogenes that drive cancer growth. A single cell contains 2-3 meters of DNA, meaning that the only way to store it is to package it into tight coils.

Scientists open door to manipulating 'quantum light'
Scientists open door to manipulating ’quantum light’
Light particles, also called photons, do not normally interact with each other. An international research team has now demonstrated for the first time that a few photons can be manipulated and made to interact in a controlled manner. This could advance both medical imaging and quantum computing. Photons do not interact with each other in a vacuum; they can fly through each other undisturbed.

Can we learn without a brain?
Can we learn without a brain?
Some animals do not need a brain to be able to learn. This is what Professor Simon Sprecher of the University of Freiburg has revealed in a study that has just been published. With his team, the biologist taught a sea anemone to adapt its behavior according to past experiences . We spontaneously associate the faculties of learning and memorization with the existence of a brain.

Following the water cycle in the forest
Following the water cycle in the forest
In the Forest Laboratory "Waldlabor" on Hönggerberg, researchers investigate the storage and transport processes of water in the forest. Recently they showed that forest-floor litter and deadwood have a far larger influence on the forest water balance than expected. The forest on Hönggerberg in the north of Zurich is both, a recreational space and a laboratory.

Lower energy consumption thanks to daylight-saving time
Lower energy consumption thanks to daylight-saving time
The abolition of daylight saving time is a frequently - and hotly - debated topic. Often, only the aspect of electricity consumption due to artificial lighting is considered. In a new study, researchers have analyzed whether daylight saving time also has an impact on the energy needed to heat and cool office buildings, and what role climate change might play in this.

How tumours transform blood vessels
How tumours transform blood vessels
Increasingly dense cell clusters in growing tumours convert blood vessels into fibre-filled channels. This makes immune cells less effective, as findings by researchers from ETH Zurich and the University of Strasbourg suggest. It was almost ten years ago that researchers first observed that tumours occurring in different cancers - including colorectal cancer, breast cancer and melanoma - exhibit channels leading from the surface to the inside of the cell cluster.
