Unexpected findings on medical imaging are usually harmless

by Helen Jaques in In Sickness and In Health

Imagine you go for an MRI or an x ray and the radiologist spots something they didn’t anticipate on your scan – you would be worried, right? Well, maybe you don’t need to be.

HEAVY METAL SHIELDS FLOWERS FROM DISEASE

by Casey Rentz in Natural Selections


Look out! This little white flower can protect itself...in a major way. Alpine pennycress, a dandelion-looking plant found growing in the dirt next to former mines can absorb metal and use it to shield itself from disease, says a recent study in PLoS Pathogens. Why are we always so surprised to witness a seemingly primitive plant or animal adapting to things in post-industrial human societies? It's their world, too.
Anyway, back to the story--Zinc, nickel, or cadmium, if sucked up in high enoug........ Read more »

What Happens When A White Dwarf Collides With A Neutron Star?

by Joseph Smidt in The Eternal Universe

                             Image via WikipediaPaschalidis et al. recently simulated what will happen when a white dwarf collides with a neutron star in a head on collision incorporating the effects of general relativity.

In each case I will list the mass of the white dwarf and neutron star in solar masses, (meaning the mass of these objects after dividing my the mass of the sun) the ratio of

Giraffes – Necks for food or necks for sex?

by Laelaps in Laelaps

The neck of a giraffe (Giraffa camelopardalis) is a marvelous thing. Comprised of only seven vertebrae* – no more than in your neck – the towering feat of natural engineering is at once stunning and ridiculous. How could such a structure have evolved? This question is not just a throw-away. For the past century and [...]... Read more »

Dali on the Brain: Voltaire and the Nuns

by Psychology 379 bloggers in Cognition & the Arts

When daring to venture into the modern art wing of your local museum, you often only superficially browse through the paintings. You pause at each one for maybe eight seconds, describing the work as modern, abstract, or thinking “oh, it’s all so ambiguous and undefined, I feel like an intellectual,” (while pausing to layer a smidgen of cheese over a cracker and audibly swill some wine). However, within the small aperture of time spent ogling a visually-ambiguous and confounding........ Read more »

Deriving Inhibitory Peptides from Globular Protein–Protein Interactions

by Nir London in Macromolecular Modeling Blog

There are several forms of peptide-protein interactions, one of which are globular PPIs mediated by a dominant linear peptide at the interface. To what extent could peptides extracted from a globular protein monomer be used to inhibit the interaction to its partner? In this work, we have investigated the possibility of deriving peptides from the interface of globular proteins to design inhibitors that would compete with their native interaction.
