Weightlessness affects health of cosmonauts at molecular level

A team of scientists from Russia and Canada has analyzed the effect of space conditions on the protein composition in blood samples of 18 Russian cosmonauts. The results indicate many significant changes in the human body ...

Protein aggregates save cells during aging

As an organism ages, a gradual loss of cellular protein quality control occurs. This results in the increased production of toxic protein clumps, so-called aggregates. Using a comprehensive approach, researchers in the teams ...

Alzheimer substance may be the nanomaterial of tomorrow

Amyloid protein causes diseases like Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease. But amyloid also carries unique characteristics that may lead to the development of new composite materials for the nano processors ...

Tiny nanocubes help scientists tell left from right

(Phys.org) —In chemical reactions, left and right can make a big difference. A "left-handed" molecule of a particular chemical composition could be an effective drug, while its mirror-image "right-handed" counterpart could ...

X-rays reveal why sea urchins are no easy prey

(PhysOrg.com) -- The spine of a sea urchin is 99.9% chalk, a very common material forming tiny crystals that are very hard but easy to break apart. Scientists have now discovered how these marine animals use chalk or lime ...

Crystal clear research

(PhysOrg.com) -- Scientists have successfully created synthetic crystals whose structures and properties mimic those of naturally occurring biominerals such as seashells.

Nanoparticles Unlock Tumor Identity

(PhysOrg.com) -- Using nanoparticles designed to recognize specific sugar-binding molecules on the surfaces of cells, a team of investigators at Michigan State University has developed a process that uses magnetic resonance ...

Genetic analysis reveals secrets of scorpion venom

Transcriptomic tests have uncovered the protein composition of venom from the Scorpiops jendeki scorpion. Researchers writing in the open access journal BMC Genomics have carried out the first ever venom analysis in this ...
