The construction sector accounts for a quarter of carbon dioxide emissions, in Sweden and globally. Researchers from Chalmers University of Technology and the University of Gothenburg studied the construction of an eight km stretch of road in detail and calculated how much emissions can be reduced now and until 2045, looking at everything from materials choice, production technology, supply chains and transport.
Roboticists at the University of California San Diego have developed an affordable, easy to use system to track the location of flexible surgical robots inside the human body. The system performs as well as current state of the art methods, but is much less expensive. Many current methods also require exposure to radiation, while this system does not.
The prospect of the widespread commercialization and application of flexible electronics has kept researchers worldwide searching for ingenious ways to enhance their performance and durability. From wearable smart devices to solar cells and health sensors, flexible electronics holds much promise in many engineering fields. Unfortunately, flexible devices are usually as fragile as they look; mechanical deformations, such as bending, can induce the formation and propagation of microscopic cracks that ultimately cause devices to fail.
KAIST physicists described a route to design the energy-efficient generation, manipulation and detection of spin currents using nonmagnetic two-dimensional materials. The research team, led by Professor Sungjae Cho, observed highly efficient charge-to-spin interconversion via the gate-tunable Rashba-Edelstien effect (REE) in graphene heterostructures.
This research paves the way for the application of graphene as an active spintronic component for generating, controlling, and detecting spin current without ferromagnetic electrodes or magnetic fields.
Researchers at the University of Eastern Finland have developed a new and promising drug compound for the treatment of cancer that inhibits natural amino acids from entering cancer cells. Since amino acids are essential for the growth and division of cancer cells, the new LAT1 inhibitor makes it possible to inhibit their growth. The study was published in the journal Apoptosis.
Lung Cancer is a leading cause of death worldwide, accounting for an estimated 2.09 million new cases in 2018 according to WHO, which is also the leading cause of cancer-related mortality in China [1].
The latest screen-time related research from Dr. Pooja Tandon, a child health and development expert at Seattle Children's Research Institute, was inspired by her oldest son.
Understanding the genetic mutations and protein changes that take place in the progression of cancer is key to its treatment. Mutations in the gene TP53 and concomitant mutant p53 proteins in cancer cells have become notorious over the course of multiple studies of several different types of cancers. Yet so far, the mechanisms behind the role of these protein changes in propagating the disease has been poorly understood.
Heating accounts for over 50 per cent of final energy consumption. So reducing the emissions that result from heating buildings would make a huge difference to the climate. What strategies are being pursued to realise this potential in Germany and the UK? A study by researchers from the Institute for Advanced Sustainability Studies (IASS) finds that both countries could do a lot more to mitigate climate change in the heating sector.
What happened yesterday and what will happen tomorrow are usually two different and quite independent matters. The past and the future of human life are not symmetric and therefore not reversible. In physics, this is different. The fundamental forces of nature in elementary particles, atoms and molecules are symmetric with respect to their development in time: Forwards or backwards makes no difference, scientists call this a time-reversal symmetry.
Researchers have uncovered the highly efficient strategy used by a group of crickets to distinguish the calls of predatory bats from the incessant noises of the nocturnal jungle. The findings, led by scientists at the Universities of Bristol and Graz in Austria and published in Philosophical Transactions of the Royal Society B, reveal the crickets eavesdrop on the vocalisations of bats to help them escape their grasp when hunted.
ANN ARBOR, Mich. -- Health apps have become a popular tool among teens and adults to track fitness, weight loss, sleep and even menstrual cycles - but are they appropriate for tweens?
Most parents say they have concerns about how health apps may impact children ages 8-12, according to the C.S. Mott Children's Hospital National Poll on Children's Health at Michigan Medicine. But despite concerns, most parents aren't against tweens using apps.
In a collaborative study in this month's issue of Engineering Structures, researchers at Princeton University and the University of Bergamo revealed the engineering techniques behind self-supporting masonry domes inherent to the Italian renaissance. Researchers analyzed how cupolas like the famous duomo, part of the Cathedral of Santa Maria del Fiore in Florence, were built as self-supporting, without the use of shoring or forms typically required.
Many people turn to 'Dr Google' to self-diagnose their health symptoms and seek medical advice, but online symptom checkers are only accurate about a third of the time, according to new Edith Cowan University (ECU) research published in the Medical Journal of Australia today.
The study analysed 36 international mobile and web-based symptom checkers and found they produced the correct diagnosis as the first result just 36 per cent of the time, and within the top three results 52 per cent of the time.
New York, NY--May 15, 2020--Researchers at Columbia Engineering and the University of South Carolina have developed a method that combines big data and machine learning to selectively design gas-filtering polymer membranes to reduce greenhouse gas emissions.
Their study, published today in Science Advances, is the first to apply an experimentally validated machine learning method to rapidly design and develop advanced gas separation membranes.
