The question of the origin of the language is one of the most important and at the same time one of the most difficult to solve. It was formulated in antiquity and has inspired religion and philosophy ever since, in some periods, above all the Enlightenment, becoming the axis of reflection on other fundamental issues, such as human nature. In the last few decades, research in this field has intensified, drawing on evolutionism and having an interdisciplinary character, involving linguists, psychologists, primatologists and neuroscientists.
Rapid 3D microscopic imaging of fluorescent samples has gained increasing importance in numerous applications in physical and biomedical sciences. Given the limited axial range that a single 2D image can provide, 3D fluorescence imaging often requires time-consuming mechanical scanning of samples using a dense sampling grid. In addition to being slow and tedious, this approach also introduces additional light exposure on the sample, which might be toxic and cause unwanted damage, such as photo-bleaching.
NIMS and the Tokyo Institute of Technology have jointly discovered that the chemical compound Ca3SiO is a direct transition semiconductor, making it a potentially promising infrared LED and infrared detector component. This compound--composed of calcium, silicon and oxygen--is cheap to produce and non-toxic. Many of the existing infrared semiconductors contain toxic chemical elements, such as cadmium and tellurium. Ca3SiO may be used to develop less expensive and safer near-infrared semiconductors.
Metallic microstructures are the key components in almost every current or emerging technology. For example, with the next wireless communication standard (6G) being established, the need for advanced components and especially antennas is unbroken. The drive to yet higher frequencies and deeper integration goes hand in hand with miniaturization and fabrication technologies with on-chip capability. Via direct laser writing - an additive manufacturing technology that offers sub-micron precision and feature sizes - highly sophisticated and integrated components come into reach.
A study has found that a new 'care bundle' can reduce the incidence of facial pressure injuries in frontline COVID-19 healthcare workers caused by the prolonged wearing of Personal Protective Equipment (PPE).
The study, led by researchers from RCSI University of Medicine and Health Sciences Skin Wounds and Trauma (SWaT) Research Centre, is published in the current edition of the Journal of Wound Care.
In 2016 the Bank of England introduced plastic (polymer) banknotes, alongside 50 other countries that use polymer banknotes
Counterfeit polymer banknotes on the streets have increased over the last few years, therefore the need to prevent and identify counterfeit banknotes has increased
Using a technique called Polymer Substrate Fingerprinting, researchers from the University of Warwick are able to identify each banknote's own fingerprint, which is unique and unclonable
CABI-led Plantwise plant clinics can help promote more sustainable ways to fight crop pests and diseases in Rwanda and Zambia - such as the fall armyworm - with the judicial use of pesticides within Integrated Pest Management (IPM) plans.
Denver--March 26, 2021---A lymph node collection kit can help surgeons attain compete resection and improve long-term survival after curative-intent lung cancer surgery, according to a study published in the Journal of Thoracic Oncology Clinical and Research Reports. The journal is published by the International Association for the Study of Lung Cancer.
The discovery of the material graphene, which consists of only one layer of carbon atoms, was the starting signal for a global race: Today, so-called "2D materials" are produced, made of different types of atoms. Atomically thin layers that often have very special material properties not found in conventional, thicker materials.
Russian scientists have proposed a new algorithm for automatic decoding and interpreting the decoder weights, which can be used both in brain-computer interfaces and in fundamental research. The results of the study were published in the Journal of Neural Engineering.
Researchers at North Carolina State University have designed and demonstrated a new system that allows them to remotely monitor the behavior of freshwater mussels. The system could be used to alert researchers to the presence of toxic substances in aquatic ecosystems.
Many organisms use sunlight to fuel cellular functions. But exactly how does this conversion of solar energy into chemical energy unfold?
In a recent experiment, an international team of scientists, including two researchers from UWM, sought answers using an advanced imaging technique called time-resolved serial femtosecond crystallography to watch a pigment found in some marine bacteria as it was exposed to sunlight outside the cell.
The BioRescue consortium develops and applies new technological approaches as a last straw for saving critically endangered species such as the northern white rhinoceros. Advanced Assisted Reproductive Technologies (aART) push the boundaries of what can be done to create new offspring. Consequently, new ethical questions regarding the application of these tools arise and need to be answered, and relevant animal welfare issues to be addressed.
Most people relate cholesterol to heart health, but it is also a critical component in the growth and spread of brain cancer. VCU Massey Cancer Center researcher Suyun Huang, Ph.D., recently discovered how cholesterol becomes dysregulated in brain cancer cells and showed that the gene responsible for it could be a target for future drugs.
Some 40% of critically ill patients who undergo tracheal intubation to support their breathing suffer a life-threatening complication, research from National University of Ireland Galway has revealed.
The study, published today in JAMA: The Journal of the American Medical Association, involved 2,964 critically ill men and women. It was carried out across 29 countries from 1 October 2018 to 31 July 2019 to determine the risk of adverse events arising from the invasive procedure.
