Embryonic development in slow motion
Research
ETH Zurich
Roe deer are among the few mammals whose embryos go into a particularly long period of dormancy. Using modern molecular methods, ETH Zurich researchers have shown for the first time exactly what happens to the embryo during this phase. They have identified signals that control the embryo`s awakening.
“Junk” DNA plays a key role in speciation
Research
ETH Zurich
Researchers propose a new framework for how satellite DNA, sometimes called “genomic junk,” is essential in the organization of chromosomes in cells. They suggest this quickly-evolving DNA is one reason different species are unable to successfully interbreed.
Recreating biology in computer language
Research
Eawag
Toxic substances in the environment can harm the nervous system of fish embryos. Now, researchers at Eawag have developed a computer model that helps to better understand how the damage occurs.
Getting oxygenated blood to exercising muscles
Research
ETH Zurich
ETH Zurich Professor Katrien De Bock and her team have discovered a certain type of blood vessel cell in muscles that multiplies rapidly upon exercise, thereby forming new blood vessels. Researchers can use this to find novel therapies for vascular disorders of the muscle.
Bacteria navigate on surfaces using a "sense of touch"
Research
EPFL
EPFL researchers have characterized a mechanism that allows bacteria to direct their movement in response to the mechanical properties of the surfaces the microbes move on — a finding that could help fight certain pathogens.
Illuminating tissue formation
Research
ETH Zurich
Researchers at ETH Zurich have developed a molecule that fluoresces where new tissue is forming in the body. Alongside helping to detect tumours, the molecule could play a significant role in research of wound healing disorders.
