Abstract Introduction Implementation of community-based healthcare services offering effective contraception, antenatal care (ANC), and treatment for symptomatic children under five has reduced maternal and child mortality in Togo. However, understanding if women are utilizing these services differentially based on social or demographic factors is important. This study identifies whether sexual relationship and socio-demographic factors...

Researchers think that the new coronavirus may bind to receptors on endothelial cells, which are found on the inside of blood vessels, like veins and arteries. (Pixabay/)COVID-19 may be causing strokes and heart attacks, even in patients who don’t seem to be at risk for those conditions. This alarming news has made headlines in recent days, but researchers say the link between infection with the new virus and these conditions is complicated and still poorly understood.J Morro, a Mount Sinai neurosurgeon,...

Sensors on the back, front, and bottom help the DJI Mavic Air 2 navigate. (DJI/)The Mavic Air is the middle child. At $799, it fits nicely between the pint-sized Mavic Mini and the more advanced Mavic Pro models. That can be an awkward position, but in DJI’s case, the Mavic Air 2—just announced today—looks more like it’s in the sweet spot.The Mavic Air 2 replaces the original, which debuted back in 2019, and features a very similar folding form factor that should be familiar at this point—the company...

You're suddenly everybody's best friend. (Jo Jo via Unsplash/)Picture this: it’s perfect outside on the longest day of the year. You’re surrounded by loved ones, and they’re all getting hungry after hours in the sun. Twilight is just starting to make its approach as you fire up the grill, an assortment of meats and veggies at the ready. Beer, margarita, or lemonade in hand, you preside over the evening’s deliciousness as people come up to chat with you. Some might even try some backseat grilling,...

Give yourself some extra support. (Carl Barcelo via Unsplash/)Even when we’re in great shape, our bodies aren’t the same day-to-day. Some days, we feel limber and can stretch easily. Other days, our muscles are tight and sore. Fortunately for most people, yoga is not a competition. The most important goal is to bring yourself to the mat to practice regularly. With these supportive yoga blocks, sink carefully into a properly-aligned pose that’s right for where you are right now.Just like the ones...

Trade your bulky machine for a light and maneuverable stick vacuum. (Amazon/)Whether we like it or not, spring cleaning is upon us. And while sponges, mops, and feather dusters are all fine and dandy, there is one cleaning tool that tops them all: the stick vacuum. This handy tool allows you to reach even the trickiest of corners in the house, to extend far beneath couches, and suck up even the most stubborn of dust bunnies. In short, it makes cleaning your home quick and hassle-free.From the creme...

A place for everything that doesn't fit in the garage. (Zoltan Tasi i/)If your spare room and garage are already short on space, a storage shed is just the place to stash your lawn mower, wheelbarrow, and other bulky home improvement gear that’s essential but not used regularly. Installing a dedicated shed for your equipment keeps it from getting rusty in the weather while safely in a space of its own and out of your way. With every imaginable material and size available, there’s a shed out there...

Have you always wanted to make a short film? (Sam McGhee via Unsplash/)Your phone delivers 4K footage and it’s always in your pocket, so why on earth would you buy a dedicated video camera? Because image resolution isn’t everything and you’ll eventually run up against the phone’s inherent limitations, like tiny sensors, static lenses, and limited controls. Among other features, video cameras often have larger 4K and 6K sensors for better color, contrast, and low-light performance; an ability to use...

The aircraft are F-16s and F/A-18s, flown by the Thunderbirds and Blue Angels, the Air Force and Navy aerial demonstrations teams. The purpose of the flights is a chance “to salute those working on the frontline of the COVID-19 response,” the Blue Angels’ commander Brian Kesselring...

Snuggly, stinky, lemurs. (Daniel C. Devor/)For ring-tailed lemurs, love stinks. They practically use body odor as a pick-up line, with ring-tails rubbing their fluffy tails into scent glands on their wrists so that they might wave the aroma around enticingly.Lemur researchers have witnessed this behavior in the wild for years, and knew the stinky courtship ritual was uniquely important to the animals’ way of life. But they weren’t sure what exactly made the smell so intriguing to females. In a paper...

Case Description During atrial septal defect repair, a pulmonary artery (PA) catheter was placed via the left internal jugular vein. Although placement of the PA catheter in the main PA was confirmed by transesophageal echocardiography, the central venous pressure (CVP) waveform was...

The study of the mechanisms involved in adaptation remains a timely issue, particularly in the context of global changes. To better understand these mechanisms of rapid adaptation, invasive species are a good model because they are subjected to new and/or different environmental factors. Using different lines of different geographical origin of the invasive pest Drosophila suzukii, we characterized the phenotypic response to oxidative stress. Subsequently, we tested the involvement of the Jheh gene...

Microorganisms are famous for adapting quickly to new environments. However, most evidence for rapid microbial adaptation comes from laboratory experiments or domesticated environments, and it is unclear how rates of adaptation scale from human-influenced environments to the great diversity of wild microorganisms. We examined potential monthly-scale selective pressures in the model forest yeast Saccharomyces paradoxus. Contrary to expectations of seasonal adaptation, the S. paradoxus population was...

The ongoing environmental crisis poses an urgent need to forecast the who, where, and when of future species extinctions, as such information is crucial for targeting conservation efforts. Commonly, such forecasts are made based on conservation status assessments produced by the International Union for Conservation of Nature (IUCN). However, when researchers apply these IUCN conservation status data for predicting future extinctions, important information is often omitted, which can impact the accuracy...

Standing genetic variation is considered a major contributor to the adaptive potential of species. The low heritable genetic variation observed in self-fertilising populations has led to the hypothesis that species with this mating system would be less likely to adapt. However, a non-negligible amount of cryptic genetic variation for polygenic traits, accumulated through negative linkage disequilibrium, could prove to be an important source of standing variation in self-fertilising species. To test...

Demographic events shape a population's genetic diversity, a process described by the coalescent-with-recombination (CwR) model that relates demography and genetics by an unobserved sequence of genealogies. The space of genealogies over genomes is large and complex, making inference under this model challenging. We approximate the CwR with a continuous-time and -space Markov jump process. We develop a particle filter for such processes, using waypoints to reduce the problem to the discrete-time case,...
