Vitamin B3 analogue boosts production of blood cells

Scientists from EPFL and the UNIL/Ludwig Cancer Research have found that supplementing diet with nicotinamide riboside, an analogue of vitamin B3, boosts the production of blood cells by improving the function of their stem cells.

CRISPR reveals the secret life of antimicrobial peptides

In France, scientists from the lab of Bruno Lemaitre at EPFL’s Global Health Institute have used CRISPR, the gene-editing technique, to delete no less than 14 AMPs from the fruit fly Drosophila. By deleting single AMP genes, various combinations of genes, or even all 14 genes, the scientists were able to remove their corresponding AMPs and observe how their absence affected the fly’s resistance to different bacterial and fungal pathogens. The results showed that, at least in Drosophila, AMPs act...

Prototype prosthesis proffers proper proprioceptive properties

Researchers have created a prosthetic hand that offers its users the ability to feel where it is and how the fingers are positioned — a sense known as proprioception. The headline may be in jest, but the advance is real and may help amputees more effectively and naturally use their prostheses. Prosthesis rejection is a real problem for amputees, and many choose to simply live without these devices, electronic or mechanical, since they can complicate as much as they simplify. Part of that is the ...

Why a blow to the chest can kill or save you

It is still a mystery why a blow to the chest can kill people by inducing cardiac arrest yet save others that are in cardiac arrest. We may be one step closer to an answer, however, thanks to a device developed by researchers of the University of Bern and the EPFL that can replicate the experience in the laboratory.

These hyper-efficient solar panels could actually live on your roof soon

The clean energy boffins in their labs are always upping the theoretical limit on how much power you can get out of sunshine, but us plebes actually installing solar cells are stuck with years-old tech that’s not half as good as what they’re seeing. This new design from Insolight could be the one that changes all that. Insolight is a spinoff from the École Polytechnique Fédérale de Lausanne, where they’ve been working on this new approach for a few years — and it’s almost ready to hit your roof....

Let’s save the bees with machine learning

Machine learning and all its related forms of “AI” are being used to work on just about every problem under the sun, but even so, stemming the alarming decline of the bee population still seems out of left field. In fact it’s a great application for the technology and may help both bees and beekeepers keep hives healthy. The latest threat to our precious honeybees is the varroa mite, a parasite that infests hives and sucks the blood from both bees and their young. While it rarely kills a bee out...

Shapeshifting microrobots to travel through your bloodstream

Continuing the quest to design robots that could travel through our bodies to deliver drugs and cure disease, researchers at EPFL and ETH Zurich demonstrated tiny shape-shifting microrobots that swim through blood vessels. Made from hydrogel nanocomposites, the microbots can fold into various shapes for easy travel through tight spaces and flowing with dense, viscous, or fast-moving liquids. The microbots are peppered with magnetic nanoparticles so that they can be "steered" with an external ma...

Chirality in 'real-time'

Distinguishing between left-handed and right-handed ('chiral') molecules is crucial in chemistry and the life sciences, and is commonly done using a method called circular dichroism. However, during biochemical reactions the chiral character of molecules may change. EPFL scientists have for the first time developed a method that uses ultrashort deep-ultraviolet pulses to accurately probe such changes in real-time in (bio)molecular systems.
