For the first time, scientists have visualized the fine details of bacterial microcompartment shells -- the organisms' submicroscopic nanoreactors, which are comprised completely of protein.
It's a tiny marine invertebrate, no more than 3 millimeters in size. But closely related to humans, Botryllus schlosseri might hold the key to new treatments for cancer and a host of vascular diseases.
In a study published in Current Biology on June 22, the lab of Professor John Werren at the University of Rochester describes how four closely related species of parasitic wasps change their venoms rapidly in order to adapt to new hosts, and proposes that co-option of single copy genes may be a common but relatively understudied mechanism of evolution for new gene functions, particularly under conditions of rapid evolutionary change.
Published in Applied Catalysis B: Environmental, the study demonstrates a process with great potential for developing technologies for reducing CO2 levels.
Exosomes - tiny biological nanoparticles which transfer information between cells - offer significant potential in detecting and treating disease, the most comprehensive overview so far of research in the field has concluded. Areas which could benefit include cancer treatment and regenerative medicine.
Noting that the prescription of proton pump inhibitors is on the rise among middle-aged and older adults, a team of researchers designed a new study to examine PPIs and the risk of dementia, mild cognitive impairment, and Alzheimer's disease. They published their study in the Journal of the American Geriatrics Society.
The anchors that hold Venus' flower basket sea sponges to the ocean floor have an internal architecture that increases their ability to bend, according to a new study. Understanding that natural architecture could inform future human-made materials.
NASA's James Webb Space Telescope was placed in Johnson Space Center's historic Chamber A on June 20, 2017, to prepare for its final three months of testing in a cryogenic vacuum that mimics temperatures in space.
joint European-US study led by experts from Niels Bohr Institute (NBI) at University of Copenhagen, Denmark, reveals a rotating stellar disk à la the Milky Way in a stone-dead galaxy 10 billion light-years from Earth. This has never been shown before. The galaxy examined is an early version of elliptical-shaped galaxies.
Researchers at the Niels Bohr Institute have introduced a new type of nanomechanical resonator, in which a pattern of holes localizes vibrations to a small region in a 30 nm thick membrane. The pattern dramatically suppresses coupling to random fluctuations in the environment, boosting the vibrations' coherence. The researchers' quantitative understanding and numerical models provide a versatile blueprint for ultracoherent nanomechanical devices. Among others, this enables a new generation of nanomechanical sensors to probe quantum limits of mechanical measurements, and more sensitive force microscopy.
