- Silver nanowires are an ideal material for current and future flexible touch-screen technologies
- Traditional touchscreen material is facing supply shortfall, as well as being unfit for flexible devices
- Material can be manufactured easily, using less energy than current material

To cope with changes in its aquatic environment and the nutrient deficiencies that may result, Chlamydomonas reinhardtii, a mobile single-cell alga, must adapt its metabolism for subsistence, notably in terms of sugar. The latter is produced by photosynthesis. To this end, plants and algae use internal cell structures called chloroplasts, which are equipped with protein complexes, the photosystems. If certain nutrients are missing, such as iron, the alga temporarily dismantles its photosystems to recycle some of their components.
A report investigating the educational needs of students with autism has identified social and emotional needs as the top priority to ensure success at school.
The Australian Educational Needs Analysis report was released at the ASPECT Autism in education conference in Melbourne's Convention & Exhbition Centre on Friday May 6.
With an increase in the numbers of children diagnosed with autism in the past 10 years, the report indicated a high rate of exclusion with social and academic needs not often understood or supported.
THE last Ice Age made much of the globe uninhabitable, but there were oases - or refugia - where people 20,000 years ago were able to cluster and survive. Researchers at the University of Huddersfield, who specialise in the analysis of human DNA, have found new evidence that there was one or more of these shelters in what is now Southern Arabia.
Once the Ice Age receded - with the onset of the Late Glacial period about 15,000 years ago - the people of this refugium then dispersed and populated Arabia and the Horn of Africa, and might also have migrated further afield.
A Japanese research group has identified the enzymes that change the grassy odor of plants into a sweeter "green" fragrance. This discovery can potentially be used to grow sweet tomatoes with less of a grassy odor. These findings were published on April 29 in The Journal of Biological Chemistry.
Mountain gorillas from Volcanoes National Park in Rwanda eat up to 30 kilos of plants a day and their diet is highly varied in a habitat that is becoming increasingly fragmented as a result of illegal hunting and deforestation. For the first time, a study shows how dental morphology adapts to the food that is available. The information from the wear on their teeth is used to identify specimens that disappear.
Many cancers could be successfully treated if the patient consulted the doctor sufficiently early. But how can a developing cancer be detected if it doesn't give rise to any symptoms? In the near future, suitably early diagnosis could be provided by simple and cheap chemical sensors - thanks to special recognizing polymer films developed at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw.
A remarkably high diversity of the wingless long-horned beetles in the mountains of northern Borneo is reported by three Czech researchers from the Palacký University, Olomouc, Czech Republic. Apart from the genera and species new to science, the entomologists report the first case of reproduction by live birth in this rarely collected group of beetles. The study was published in the open access journal ZooKeys.
A doctoral student at the University of Pennsylvania has identified a new species of fossil dog. The specimen, found in Maryland, would have roamed the coast of eastern North America approximately 12 million years ago, at a time when massive sharks like megalodon swam in the oceans.
It's been more than 30 years since the invention of 3-D printing, and yet in some ways the technology is still a frontier of unexplored potential.
Three-dimensional printing -- and additive manufacturing in general -- is the process of depositing material, layer by layer, in patterns determined by computer software, to precisely fabricate a three-dimensional object. The technology has been used to make hip and dental implants, as well as architectural models and aerospace tools, including a socket wrench that astronauts recently printed aboard the International Space Station.
Attosecond light pulses in the extreme ultraviolet have drawn a great deal of attention due to their ability to interrogate electronic dynamics in real time. Nevertheless, to follow charge dynamics and excitations in materials, element selectivity is a prerequisite, which demands such pulses in the soft X-ray region, above 200 eV, to simultaneously cover several fundamental absorption edges of the constituents of the materials.
New research from the University of Pittsburgh School of Medicine suggests two simple ways dermatologists can make patients more comfortable during full-body skin cancer checks: respect patient preferences for the physician's gender as well as whether, and how, they prefer to have their genitals examined. The findings are published online today in JAMA Dermatology.
DENVER - Immunohistochemistry (IHC) is an effective tool that can be used for identifying proto-oncogene 1 receptor tyrosine kinase (ROS1) gene rearrangements and screening patients for the administration of the targeted therapy crizotinib, a small-molecule tyrosine kinase inhibitor.
- Researchers exposed rodents' lung and skin cells to different oxygen concentrations to observe how they react
- Despite popular belief that sensitivity to oxidative stress is associated with a decreased lifespan, the study found this was not the case in the majority of rodents
- Laboratory mouse strains are atypically sensitive to oxidative stress compared to wild mice and may not be a good model for aging research
- Findings offer new opportunities to further investigate how to slow down the ageing process in humans
A new UBC-developed method to isolate cancer cells that have escaped from a tumour could soon pave the way for improved diagnosis and treatment.
The simple process involves a special device that squeezes cells in a blood sample through tiny funnels, which drive the cancer cells and blood cells into separate streams based on differences in their size and softness.
