Over the last two decades, biomaterials research has made significant progress, transitioning from traditional biomaterials to biomaterials with controlled structure and dynamic functionality. A number of building blocks have been explored for developing biomaterials by self-assembly, but SAPs have garnered special attention due to their tunability and potential use in various applications such as tissue engineering, wound healing, and vaccinations. Despite these benefits, the SAP-based approach is less explored in the intracellular context.
Most babies born prematurely or with health problems are quickly whisked away to the Neonatal Intensive Care Unit (NICU) where they might require assisted heating devices to regulate their temperature. A University of Houston College of Nursing researcher is reporting that the traditional use of cloth blankets and towels during peripherally inserted central catheter (PICC) placement may hinder heat transfer from the assisted heating mechanisms, increasing the risk for neonatal hypothermia.
Scientists have developed a new technology to detect a wider variety of T cells that recognize coronaviruses, including SARS-CoV-2. The technology revealed that killer T cells capable of recognizing epitopes conserved across all coronaviruses are much more abundant in COVID-19 patients with mild disease versus those with more severe illness, suggesting a protective role for these broad-affinity T cells.
More than 80 percent of people around the world consider themselves to be religious or spiritual. But research on the neuroscience of spirituality and religiosity has been sparse. Previous studies have used functional neuroimaging, in which an individual undergoes a brain scan while performing a task to see what areas of the brain light up. But these correlative studies have given a spotty and often inconsistent picture of spirituality.
People lived without plastic until the last century or so, but most of us would find it hard to imagine how.
Plastics now are everywhere in our lives, providing low-cost convenience and other benefits in countless applications. They can be shaped to almost any task, from wispy films to squishy children's toys and hard-core components. They have shown themselves vital in medicine and have been pivotal in the global effort to slow the spread of the COVID-19 pandemic over the past 16 months.
Plastics seem indispensable these days.
As smart watches are increasingly able to monitor the vital signs of health, including what's going on when we sleep, a problem has emerged: those wearable, wireless devices are often disconnected from our body overnight, being charged at the bedside.
"Quality of sleep and its patterns contain a lot of important information about patients' health conditions," says Sunghoon Ivan Lee, assistant professor in the University of Massachusetts Amherst College of Information and Computer Sciences and director of the Advanced Human Health Analytics Laboratory.
WASHINGTON -- If you've ever tried to capture a sunset with your smartphone, you know that the colors don't always match what you see in real life. Researchers are coming closer to solving this problem with a new set of algorithms that make it possible to record and display color in digital images in a much more realistic fashion.
Evidence shows significant reduction in indicators of potential harm over 6-months for smokers switching to exclusive use of glo compared with continuing to smoke cigarettes
Gold-standardi indicator supports scientific substantiation of glo's potential as a reduced risk product*
First ever long-term study showing sustained reduction in exposure to certain toxicants and indicators of potential harm in smokers switching completely to glo
SAN ANTONIO (June 30, 2021) — In a U.S. and Swiss study, nearly all patients with cancer developed good immune response to the COVID-19 mRNA vaccines three to four weeks after receiving their second dose, but the fact that a small group of the patients exhibited no response raised questions about how their protection against the virus will be addressed moving forward.
Scientists show that an ocean-bottom seismometer deployed close to the calving front of a glacier in Greenland can detect continuous seismic radiation from a glacier sliding, reminiscent of a slow earthquake.
Over the past 20 years, many studies have investigated the effects of acute aerobic exercise on cognitive performance. In recent years, meta-analyses*1 of data from these previous research studies have demonstrated that these a single bout of moderate aerobic exercise temporarily improves cognitive performance. However, close examination of the individual research studies on this topic revealed that in approximately 50% of studies, no beneficial link between acute aerobic exercise and cognitive function was found.
Ibaraki, Japan - Flowers come in a multitude of shapes and colors. Now, an international research team led by a researcher from Japan has proposed the novel hypothesis that trade-offs caused by different visitors may play an important role in shaping this floral diversity.
In a study published last month, the team explored how the close associations between flowers and the animals that visit them influence flower evolution.
Plastic waste is considered one of the biggest environmental problems of our time. IASS researchers surveyed consumers in Germany about their use of plastic packaging. Their research reveals that fundamental changes in infrastructures and lifestyles, as well as cultural and economic transformation processes, are needed to make zero-waste shopping the norm.
Election outcomes are notoriously difficult to predict. In 2016, for example, most polls suggested that Hillary Clinton would win the presidency, but Donald Trump defeated her. Researchers cite multiple explanations for the unreliability in election forecasts -- some voters are difficult to reach, and some may wish to remain hidden. Among those who do respond to surveys, some may change their minds after being polled, while others may be embarrassed or afraid to report their true intentions.
