Chip-based nanoscopy: Microscopy in HD quality

Mon, 24/04/2017 - 3:08pm
Physicists have developed a photonic chip that makes it possible to carry out super-resolution light microscopy, also called 'nanoscopy,' with conventional microscopes. In nanoscopy, the position of single fluorescent molecules can be determined with a precision of just a few nano-meters, that is, to a millionth of a millimeter.

After the death of a friend, healing in a human social network

Mon, 24/04/2017 - 3:08pm
The first large-scale study of recovery and resilience after a death in a friend group -- based on analysis of interactions in 15,000 anonymized networks on Facebook -- finds that when a friend dies, we get closer to that person's friends. The social network repairs itself in ways that keep our total connectedness the same.

Disease-associated genes routinely missed in some genetic studies

Mon, 24/04/2017 - 3:07pm
New research reveals two new ways to identify genes that routinely are missed in studies using a common gene-sequencing method. Many of these missed genes are associated with leukemia, psoriasis, heart failure, and other diseases. As part of their new research, the team of scientists have packaged their new methods into open-source software for other researchers to use.

Freezing lithium batteries may make them safer, bendable

Mon, 24/04/2017 - 2:16pm
A new method that could lead to lithium batteries that are safer, have longer battery life, and are bendable has now been developed, providing new possibilities such as flexible smartphones. His new technique uses ice-templating to control the structure of the solid electrolyte for lithium batteries that are used in portable electronics, electric vehicles, and grid-level energy storage.

Recommendation against inhaled flu vaccine is good -- for now

Mon, 24/04/2017 - 2:12pm
Recent federal recommendations against offering the inhaled nasal influenza vaccine due to lack of effectiveness could lead to more flu illness in the US if the inhaled vaccine becomes effective again or if not having the choice of the needle-less vaccine substantially reduces immunization rates, according to a new analysis.

Alternating skimpy sleep with sleep marathons hurts attention, creativity in young adults

Mon, 24/04/2017 - 2:12pm
Skimping on sleep, followed by 'catch-up' days with long snoozes, is tied to worse cognition -- both in attention and creativity -- in young adults, in particular those tackling major projects, researchers have found.

Photosynthesis in the dark? Unraveling the mystery of algae evolution

Mon, 24/04/2017 - 2:12pm
Researchers compared the photosynthetic regulation in glaucophytes with that in cyanobacteria, to elucidate the changes caused by symbiosis in the interaction between photosynthetic electron transfer and other metabolic pathways. Their findings suggest that cyanelles of the glaucophyte Cyanophora paradoxa retain many of the characteristics observed in their ancestral bacteria, and that C. paradoxa is the primary symbiotic algae most similar to cyanobacteria than other lineages of photosynthetic organisms in terms of metabolic interactions.

New breakthrough in battery charging technology

Mon, 24/04/2017 - 2:12pm
A new study has introduced a new battery charging technology that uses light to charge batteries. This newly-developed power source is designed to work under sunlight and indoor lighting, allowing users to power their portable electronics anywhere with access to light. In addition, the new device could power electric devices even in the absence of light.

Novel method to detect toxic effects of chemicals could reduce need for animal testing

Mon, 24/04/2017 - 2:12pm
Traditional toxicological investigations performed on animals (in vivo) are expensive, time-consuming and may cause animal suffering. But new research demonstrates that a neuronal cell model, derived from mouse, can be used to evaluate the neurotoxic effect of chemicals. The alternative toxicity risk assessment could reduce reliance on animal testing while also enable quick large scale toxicity evaluations.
