New microscope peers at subcellular gears in action

Thanks to a new microscope that captures 3-D images of subcellular activity in real time, scientists can trace the pathways of nerve cells that form synapses in the brain, observe developmental activity in fertilized eggs, or follow progress of proteins that clump together to cause disease, among other imaging feats once thought impossible.

Intelligent materials that work in space

ARQUIMEA, a company that began in the Business Incubator in the Science Park of the Universidad Carlos III de Madrid (UC3M), will be testing technology it has developed in the International Space Station. The technology is based on intelligent materials that allow objects to be sent into orbit without the use of explosives.

Triplet Threat from the Sun

Researchers from the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have shown that certain peptides (small proteins) degrade under UV light by first passing through a triplet quantum state, a reactive arrangement that can cause greater damage than fragmentation alone. Their results, described in a paper appearing this week in The Journal of Chemical Physics, from AIP Publishing, explore this pathway of protein degradation and could facilitate the development of better UV protection mechanisms.

New imaging probe detects drug-resistant bacteria

A new molecular imaging probe can detect whole-body infection by Enterobacteriaceae in mice, as well as antibiotic-resistant strains of the bacteria known as CRE. The probe can also distinguish between true infection and non-pathogenic inflammation.

According to a study, species diversification in post-Cambrian clades associated with anatomical traits may be driven to a greater extent by hastened extinction of primitive taxa without the trait than by high rates of diversification among derivative taxa with the trait.

Bone remodeling in billfish

A study finds that the heavily-loaded rostral bones of billfishes, such as marlins and swordfish, are maintained by remodeling despite lacking osteocyte cells, which are abundant in the bones of mammals and were previously considered essential for detecting and repairing bone damage. A basic tenet of bone biology states that bone strength is maintained by remodeling, in which osteocytes detect and orchestrate the repair of micro-damage caused by repeated loading.

El Niño Southern Oscillation and flood risk

Global variability in flooding and risk of economic damage is influenced by the El Niño Southern Oscillation (ENSO), with higher or lower than normal damage occurring during ENSO years depending on geographical location, according to a study. ENSO is characterized by extended periods of above or below average sea surface temperatures west of South America and can cause extreme climate fluctuations around the world that sometimes result in severe weather events including hurricanes, flooding, or drought.

Stress, biological dysfunction, and type 2 diabetes

A study suggests a link between type 2 diabetes, increased exposure to stress, and a weakened biological ability to recover from stress. Epidemiological studies have suggested a link between psychological stress processes and biological dysfunction in the development and progression of type 2 diabetes, but the mechanisms underlying this relationship remain unclear.

Grafted neurons and Parkinson disease

Researchers report that grafted neural stem cells may partially reverse the symptoms of Parkinson disease in rats via the direct release of dopamine into a part of the forebrain known as the striatum. Loss of dopaminergic neurons and a corresponding decline in dopamine release are hallmark signs of Parkinson disease.

Inflammation and risk for depression

A cytokine called interleukin-6 may be a risk factor for the development of depression, a study in mice suggests. Depression and anxiety are associated with high levels of inflammatory molecules called cytokines, but it has not been clear whether inflammation causes these stress-related disorders.

Health problems and neighborhood attainment

Health problems might drive socially vulnerable individuals to live in poor neighborhoods after a natural disaster, according to a study. Researchers have known that individuals who live in poor neighborhoods tend to have worse health outcomes than those who live in wealthy neighborhoods, but previous research has focused on the effects of neighborhood on health and not vice versa.

Resting memory processing and future learning

Processing of memories during rest periods may enhance future learning, especially learning of related content, according to a study. Offline memory processing, such as spontaneous reactivation of memories during rest, can strengthen memories, although the effect of offline processing on future encoding of new memories is unknown.

Disease transmission and antibiotic-induced hyperinflammation

Highly infectious individuals within a population, known as superspreaders, may be more tolerant to intestinal perturbations caused by antibiotic treatment than non-superspreaders, according to a study. Superspreaders comprise a minority of infected hosts but spread the majority of infections to new hosts.

When herbivore numbers drop, plants ditch thorny defenses

Plants can persist in landscapes full of hungry herbivores either by shielding themselves with special defenses, or by putting down roots in regions where carnivores – who hunt the herbivores – roam. The study revealing these results shows how predation and plant defenses interact to shape plant communities.

Unlocking a youthful brain

Researchers show in mice that it’s possible to return adult neural circuits to a more youthful, immature state by targeting a receptor in the brain called PirB. Developing therapeutics to block PirB could potentially help patients recover faster from brain injury or stroke, or improve learning and memory in developmental disorders.
