Tropical forests are being cleared for agriculture and other uses at alarming rates. While scientists say it is essential to protect old-growth forests and stop further deforestation, studies by an international team of tropical ecologists — including Clemson University professor Saara DeWalt — showed that naturally regrowing forests recover surprisingly fast and can play a role in climate change mitigation.

The 2010 Deepwater Horizon oil spill was the largest marine oil spill in United States history. The disaster was caused by an explosion on the Deepwater Horizon oil rig, taking 11 lives and releasing nearly 210 million gallons of crude oil into the Gulf of Mexico. Twelve years and hundreds of millions of dollars later, scientists are still working to understand where all this oil ended up, a concept known as environmental fate.

Irvine, Calif., Feb. 16, 2022 — Wearable activity trackers are not only popular with consumers but also commonly employed by clinicians for both real-time and remote monitoring of patients’ physical fitness. When these devices are used as healthcare monitoring tools in medical research studies, however, there’s an issue: inconsistency.

University of Utah researchers know well how rock towers and arches shimmy, twist and sway in response to far-off earthquakes, wind and even ocean waves. Their latest research compiles a first-of-its-kind dataset to show that the dynamic properties, i.e. the frequencies at which the rocks vibrate and the ways they deform during that vibration, can be largely predicted using the same mathematics that describe how beams in built structures resonate.

Ivermectin is not approved by the FDA to treat or prevent COVID-19. Nonetheless, prescriptions of ivermectin by U.S. health care providers increased more than tenfold from 3,589 per week pre-COVID-19 to 39,102. In addition, the NIH, WHO and European Medicine Agency have all advised against using ivermectin to treat or prevent COVID-19. Researchers urge all health care providers to always prioritize compassion with reliable evidence on efficacy and safety. As such, they recommend a moratorium on prescribing ivermectin to treat or prevent COVID-19, except to provide the necessary evidence in data from large-scale randomized trials.

The researchers found that increased viral load in nasal samples was associated with higher viral loads in the air and on surfaces in the room. In addition, increased filtration and ventilation significantly reduced viral loads in the air and on surfaces. And higher relative humidity reduced viral particles in the air by half, while leading to more viral particles on surfaces, where they are less likely to spread disease.

The ocean twilight zone, also called the mid-water or the mesopelagic, lies far beneath the sunlit surface waters, about 650 to 3,300 feet deep to be exact. This region is a fundamental part of the ocean that has great benefit to humans – and scientists are working hard to learn more on its role in global climate. The ocean twilight zone helps to transport carbon from the upper ocean into deeper waters, where it is removed from the atmosphere for hundreds to thousands of years. In the process, the zone can act as a buffer to climate change, slowing the effects of human carbon emissions. Without the benefits that it provides, CO2 levels in the atmosphere would jump by nearly 50 percent, amplifying the speed and severity of climate change. Yet how could the twilight zone simply stop working?

This is the first pediatric study to link many neighborhood-level factors that influence health – such as quality of schools, housing, safety, and economic opportunity – to timely surgical care access.

Researchers at Michigan Medicine have developed a novel method of measuring growth in the aorta that may help clinicians to identify potentially fatal heart conditions earlier. The technique, called vascular deformation mapping, measures changes in the thoracic aorta by using high-resolution CT imaging to calculate three-dimensional changes in the aortic wall. In the study, VDM significantly outperformed the standard manual rating methods performed by experts.

Eyespots, the circular markings of contrasting colours found on the wings of many butterfly species, are used by these fluttering creatures to intimidate or distract predators. A team of scientists led by Professor Antónia Monteiro from the National University of Singapore (NUS) conducted a research study to better understand the evolutionary origins of these eyespots, and they discovered that eyespots appear to have derived from the recruitment of a complex network of genes that was already operating in the body of the butterflies to build antennae, legs, and even wings.

Inspired by the tsetse fly, scientists have developed a theory about how an individual’s age and experience affect investment in their offspring. Parents face a trade-off between putting resources into their offspring versus using resources to enhance their chances of survival so they can have more offspring. The best allocation of resources depends on age. More experienced parents are better at getting food, so they can pass on more to their offspring. However, resources are needed to combat ‘wear and tear’, so in old age less can be passed on.
