High-resolution 3D images of polymer solar cells reveal new insights into their nanoscale structure and effect on performance. Researchers shed light on operational principles, highlighting potential for cost-effective, flexible, and lightweight technology.
A new sensor array can detect multiple airborne toxins in a matter of seconds, providing essential monitoring for workers handling chemicals. The technology uses colorimetric sensors that are not affected by humidity, making it more reliable than previous electronic-nose technologies.
Studies suggest that genetic factors, particularly those related to monoamine neurotransmitters, may contribute to the development of conduct disorders. Variations in genes encoding enzymes such as MAO-B have been linked to increased risk of antisocial behaviour, with associations strengthening when environmental factors are considered.
Researchers have identified the 'master gene' E4bp4, which drives blood stem cells to produce disease-fighting Natural Killer immune cells. The discovery could lead to new ways to treat cancer and autoimmune diseases by boosting the body's production of these frontline tumour-killing cells.
Researchers identified two proteins, C/EBPα and β, that control the transition from stem cell to skin cell development in mice. Mice lacking these proteins had defective skin formation and died shortly after birth. The study sheds light on the mechanisms involved in skin cancer and other epithelial cancers.
The University of Utah has developed a two-minute water quality monitoring method that uses a handheld color sensor to detect iodine or silver levels in drinking water. The system is designed to be simple, low-cost and safe for use on the International Space Station.
A team of scientists has confirmed a major link between declining CO2 levels and the formation of Antarctica's ice caps. The study found that atmospheric CO2 levels reached a tipping point of around 760 parts per million when the Antarctic ice sheet began to form.
A University of Warwick researcher has demonstrated that an Xbox chip can be used as a cheaper alternative for modeling complex processes like cardiac arrhythmias. The study found that the XBox 360 GPU can perform high-end parallel computing on domestic hardware, saving researchers thousands of pounds.
A new endothelin type A antagonist, darusentan, provides significant reduction in blood pressure for patients with treatment-resistant hypertension. The study shows that darusentan is generally well-tolerated, but fluid retention is a main adverse effect.
A new study by an international team of researchers argues that the current definition of nanoparticles is not specific enough to determine their potential impact on human health and the environment. The study suggests that only particles smaller than 30 nanometers should be scrutinized for their unique properties.
A new structure of the zinc transporter protein has been revealed, showing how it senses and regulates zinc levels in cells. The discovery suggests an auto-regulatory mechanism for zinc transport and may lead to the development of treatments for diseases like seizure disorders or diabetes.
Researchers at UCSF have developed a way to control mammalian cells using light, enabling the creation of 'microscopic robots' that can follow light beams or stop on command. This breakthrough offers new possibilities for cancer and cardiovascular research, as well as potential applications in nerve growth and repair.
A new optoelectronic nose can detect and identify 19 toxic industrial chemicals, including ammonia and sulfur dioxide, in a matter of seconds. The wearable sensor uses a disposable array with 36 dyes that change colors when exposed to different chemicals.
Researchers discovered molecular evidence supporting Darwin's theory of evolution, finding that complex machines evolved through a process of combination and modification of existing proteins. The study provides a blueprint for understanding the evolution of cellular machinery, contradicting Intelligent Design explanations.
