Nanodiscs catch misfolding proteins red-handed

2 hours 55 min ago
When proteins misfold, accumulate and clump around insulin-producing cells in the pancreas, they kill cells. Now, researchers have obtained a structural snapshot of these proteins when they are most toxic, detailing them down to the atomic level.

What does hair loss have to teach us about cancer metastasis?

2 hours 55 min ago
Researchers have identified a signaling pathway regulating cell migration and metastasis. Unexpected hair loss in a preclinical model helped them to identify the pathway. When cells within the skin that maintain hair follicles migrate too often, hair follicle maintenance is disrupted. Researchers speculated that this pathway might also play a role in cancer cell migration. Indeed, they showed that disrupting this pathway in preclinical models increased metastasis.

3-D nanoscale imaging made possible

5 hours 30 min ago
Imaging at the nanoscale is important to a plethora of modern applications in materials science, physics, biology, medicine and other fields. Limitations of current techniques are, e.g. their resolution, imaging speed or the inability to look behind opaque objects with arbitrary shapes. Scientists have now demonstrated a method for meeting this challenge with stunning properties.

Exposure to larger air particles linked to increased risk of asthma in children

5 hours 53 min ago
Researchers report statistical evidence that children exposed to airborne coarse particulate matter — a mix of dust, sand and non-exhaust tailpipe emissions, such as tire rubber — are more likely to develop asthma and need emergency room or hospital treatment for it than unexposed children.

The locomotion of hominins in the Pleistocene was just as efficient as that of current humans

5 hours 55 min ago
Researchers have analyzed the influence of body proportions on the cost of locomotion by means of an experimental energetic study with 46 subjects of both sexes, whose results indicate that the walk of Pleistocene hominins was no less efficient energetically than that of current humans.

Nanoparticles as a solution against antibiotic resistance?

7 hours 2 min ago
Scientists have succeeded in developing an efficient method to treat mucoviscidosis. Crucial are nanoparticles that transport the antibiotics more efficiently to their destination. First of all, the active particles need to have a certain size to be able to reach the deeper airways and not to bounce off somewhere else before. Ultimately, they have to penetrate the thick layer of mucus on the airways as well as the lower layers of the bacteria biofilm.
