A Southern California high school junior has built a low-cost seismometer device that delivers earthquake early warnings for homes and businesses. Costing less than $100 for her to make today, the seismometer could someday be a regular household safety device akin to a smart smoke detector.
Oxygen radicals in the body are generally considered dangerous because they can trigger something called oxidative stress, which is associated with the development of many chronic diseases such as cancer and cardiovascular disease. In studies on mice, scientists at Goethe University Frankfurt have now discovered how oxygen radicals, conversely, can also reduce the risk of cancer and mitigate...
Dr. Sabrina Coninx from Ruhr-Universität Bochum and Dr. Peter Stilwell from McGill University, Canada, have investigated how philosophical approaches can be used to think in new ways about pain and its management. The researchers advocate not merely reducing chronic pain management to searching and treating underlying physical changes but instead adopting an approach that focuses on the person...
In celebration of the 31st anniversary of the launching of NASA's Hubble Space Telescope, astronomers aimed the renowned observatory at a brilliant "celebrity star," one of the brightest stars seen in our galaxy, surrounded by a glowing halo of gas and dust.
In celebration of the 31st anniversary of the launching of the NASA/ESA Hubble Space Telescope, astronomers aimed the celebrated observatory at one of the brightest stars seen in our galaxy to capture its beauty.
Strawberry geranium (Saxifraga stolonifera) has been used in Japan as a herbal medicine to treat wounds and swelling, and continues to be an ingredient in food and cosmetics. Pharmacological studies have shown that extracts of strawberry geranium have antioxidant and antitumor activities. However, the anti-inflammatory effect of strawberry geranium on the skin had not been well characterized.
A new study, conducted by three UC Davis Comprehensive Cancer Center researchers, studies young adult smoking trends three years after the start of California's law raising the sales age of tobacco to 21.
* High-level vaccine efficacy of 77% in African children achieve WHO-specified efficacy goal of 75%* Vaccine, trialled in 450 children, shows favourable safety profile and was well-tolerated* Vaccine candidate, R21/Matrix-M, has excellent potential for large-scale manufacturing and low-cost supply
Mount Sinai Researchers Find That Blood Clotting Drug Commonly Used for Surgeries Does Not Increase Complications for High-Risk Patients
People with type 2 diabetes tend to have poorer muscle function than others. Now a research team at Lund University in Sweden has discovered that in type 2 diabetes, a specific gene is of great importance for the ability of muscle stem cells to create new mature muscle cells. The findings are published in Nature Communications.
The new alloys created by NUST MISIS scientists in cooperation with LG Electronics will help reduce the weight of radiators and heat removal systems in electric vehicles and consumer electronics by one third. The research results are published in the Journal of Magnesium and Alloys.
When a patient with chest pain arrives at hospital, time is of the essence. Doctors must quickly rule heart attack in or out and start treatment as soon as possible. A new study reveals blood biomarkers that could help. By analyzing blood samples from patients with chest pain, researchers found a unique fingerprint of heart attack in the form of blood biomarkers. The results could help doctors to...
Newly published papers with data from polls of teens and young adults about COVID prevention show that messaging around their role in protecting others may resonate best in new efforts to promote prevention and vaccination.
Cardiovascular disease, the most common cause of death, is the result of oxygen deprivation as blood perfusion to affected tissue is prevented. To halt the development of the disease and to promote healing, re-establishment of blood flow is crucial. Researchers at Uppsala University have now discovered that one of the most common immune cells in the human body, macrophages, play an important role...
Researchers from Osaka University and JOANNEUM RESEARCH develop ultrathin piezoelectric flexible patches that harvest the body's energy to monitor the patient's pulse and blood pressure. This work may lead to novel biosensors and self-powered wearable electronics.
: A study of 2.4 million hospitalised cannabis users has found that those with an arrhythmia were 4.5 times more likely to die while in hospital than those without. The research is presented at EHRA 2021, an online scientific congress of the European Society of Cardiology (ESC). "People should be aware of this devastating outcome and be careful when using cannabis if they have a concomitant heart...
Marinas are highly modified ecosystems that have a great impact on marine biota. On the one hand, they alter the area's hydrodynamism, tending to concentrate pollutants (heavy metals, hydrocarbons, etc.). In addition, recreational boats can transport invasive species.
Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist at the University of Basel has now proposed a new scheme for such measurements that uses a particular kind of correlation between quantum particles.
New research led by Curtin University has revealed how radar satellites can improve the ability to detect, monitor, prepare for and withstand natural disasters in Australia including bushfires, floods and earthquakes.
The Red Sea is a fascinating and still puzzling area of investigation for geoscientists. Controversial questions include its age and whether it represents a special case in ocean basin formation or if it has evolved similarly to other, larger ocean basins. Researchers from Germany, Saudi Arabia and Iceland have now published a new tectonic model that suggests that the Red Sea is not only a typical...
In the first experimental pain study of CBD in humans, researchers led by Syracuse University's Martin De Vita and Stephen Maisto conclude that CBD pain relief is driven by both pharmacological action and psychological placebo effects. The research is published in the American Psychological Association's Journal of Experimental and Clinical Psychopharmacology.
Anastasia Malashina, a doctoral student at HSE University, has proposed a new method to assess vulnerabilities in encryption systems, which is based on a brute-force search of possible options of symbol deciphering. The algorithm was also implemented in a programme, which can be used to find vulnerabilities in ciphers. The results of the study were published in a paper 'Software development for...
Researchers realized efficient frequency conversion in microresonators via a degenerate sum-frequency process, and achieved cross-band frequency conversion and amplification of converted signal through observing the cascaded nonlinear optical effects inside the microresonator.
Batteries are a part of everyday modern life, powering everything from laptops, phones and robot vacuums to hearing aids, pacemakers and even electric cars. But these batteries potentially pose safety and environmental risks.
