Russian researchers present a smart material with unique properties, which holds promise for express DNA analysis and next-generation drugs against cancer and other serious diseases.
People rely on a highly tuned sense of touch to manipulate objects, but injuries to the skin and the simple act of wearing gloves can impair this ability. In this week's Applied Physics Reviews, scientists report the development of a new tactile-enhancement system based on a highly sensitive sensor. The sensor has remarkable sensitivity, allowing the wearer to detect the light brush of a feather. This crack-based sensor was inspired by a spider's slit organ.
The continuing epidemic of pre-term births includes this stark reality: tiny, fragile babies are born with underdeveloped lungs and prone to lifelong respiratory infections and related chronic illnesses. Researchers report new findings in Immunity that that will help in the development of new and cost effective methods to boost innate lung immunity in preterm babies.
Engineers from Duke University are reporting results from the first large-scale, real-world field trials of critical components of their off-grid sanitation system funded by the Bill & Melinda Gates Foundation's 'Reinvent the Toilet' program. Besides being pleasantly surprised at the longevity of their system and discovering their nutrient removal processes needed improvement, the Duke researchers were reminded of just how important cultural practices can be to the success of a global engineering challenge.
A new study in rats suggests that the natural antioxidant L-ergothioneine could alleviate the characteristics of pre-eclampsia. Researchers at DTU Biosustain work to produce L-ergothioneine biologically.
Scientists have created one of the most detailed maps of breast cancer ever achieved, revealing how genetic changes shape the physical tumour landscape, according to research funded by Cancer Research UK and published in Nature Cancer today (Monday). An international team of scientists has developed intricate maps of breast tumour samples, with a resolution smaller than a single cell.
Scientists have a developed a new technique to decipher how millions of individual cells are communicating with each other in miniature tumours grown in the lab, known as organoids, according to new research published in Nature Methods today (Monday). This is the first time that scientists have been able to analyse many different signalling molecules at once in individual cells within replicas of patients' tumours.
Like finding a needle in a haystack, Liviu Movileanu can find a single molecule in blood.
Genes are like instructions, but with options for building more than one thing. Daniel Larson, senior investigator at the National Cancer Institute, studies this gene 'splicing' process, which happens in normal cells and goes awry in blood cancers like leukemia.
Sleep-deprived fruit flies helped reveal what induces sleep. University of Oxford researchers Anissa Kempf, Gero Miesenböck, and colleagues reveal that fruit fly sleep is driven by oxidative stress, the imbalance of free radicals and antioxidants in the body.
