Unemployment among the youth is a serious problem in many developing countries, especially in Africa. This issue stems in great part from a stagnant manufacturing sector. Firms in African countries have failed to grow significantly over the past decade, leading to fewer job positions for the youth. Foreign direct investment (FDI) is a promising avenue for addressing this challenge. Local firms in developing countries can learn advanced technologies and management strategies from multinational companies. This transmission of knowledge, in general, helps make ...

G protein-coupled receptors (GPCRs) are the largest and most diverse group of cell surface proteins in humans. These receptors, which can be seen as ‘traffic directors,’ transmit signals from the outside to the inside of cells and are involved in many physiological processes. Given their prominent roles in cellular communication, cell growth, immune responses, and sensory perception, many drugs have been developed to target GPCRs, for the treatment of conditions such as asthma, allergies, depression, hypertension, and heart disease. In fact, more than 300 GPCR-related drugs are currently in clinical trials, 36% ...

Proteins are important molecules that perform a variety of functions essential to life. To function properly, many proteins must fold into specific structures. However, the way proteins fold into specific structures is still largely unknown. Researchers from the University of Tokyo developed a novel physical theory that can accurately predict how proteins fold. Their model can predict things previous models cannot. Improved knowledge of protein folding could offer huge benefits to medical research, as well as to various industrial processes. You are literally made of proteins. These chainlike molecules, made from tens to thousands of smaller molecules called amino acids, form things like hair, ...

Toronto, ON — New research from the University of Toronto has revealed the mental health toll of the COVID-19 pandemic on older adults with peptic ulcer disease (PUD), a painful condition in which gastric sores develop in the lining of the stomach or upper portion of the small intestine. The researchers examined a subsample of older adults from the Canadian Longitudinal Study on Aging, a national dataset of older Canadians. The sample consisted of 1,140 older adults with PUD, of whom 689 had a pre-pandemic history of depression and 451 had no history of depression. By using longitudinal data, the researchers were ...

Key takeaways: Eating more than one weekly serving of red meat may raise type 2 diabetes risk. Replacing red meat with plant-based protein sources, such as nuts and legumes, may reduce risk of type 2 diabetes. Embargoed for release: Thursday, October 19, 4:00 AM ET Boston, MA — People who eat just two servings of red meat per week may have an increased risk of developing type 2 diabetes compared to people who eat fewer servings, and the risk increases with greater consumption, according to a new study led by researchers from Harvard T.H. ...

Grouping English learners together in classrooms, a longstanding practice in schools, has no impact—positive or negative—on reading development for elementary school students, shows a new study by a team of literacy education researchers. “When I taught middle school 20 years ago, I noticed that my English learner students were separated from their native English-speaking peers all day long,” says NYU Steinhardt associate professor Michael Kieffer, the study’s lead author. “Data show that this practice continues in many places today, ...

Arlington, Va. — October 19, 2023 — A new report published today in the American Journal of Infection Control (AJIC) demonstrates that implementing a dedicated team of nurses to assist with central line insertions can reduce patients’ risk of developing bloodstream infections due to those central lines. In this report, infection preventionists at UNC Health found that having this dedicated team reduced the proportion of central line-associated bloodstream infections occurring within ...

Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. The damage – attributed to a 30% rise in sea temperatures caused by the Indian Ocean dipole – harmed up to 80% of the reefs in certain parts of the seabed, at depths previously thought to be resilient to ocean warming. However, scientists say it serves as a stark warning of the harm caused in our ocean by rising ocean temperatures, and also of the hidden damage being caused throughout the natural world as a result of climate change. The findings, highlighted in a study published ...

Of all the mammals, bats have one of the poorest fossil records, with palaeontologists estimating that about 80 per cent of it is missing. This has made it difficult to pinpoint exactly when they first began to fly, or began roosting in caves, or developed their unique way of ‘seeing’ their surroundings in the dark using sound – called echolocation. But a near-perfectly preserved bat’s skull discovered by French palaeontologists in a cave that dates back about 50 million years has shed new light on what we thought we knew about this ancient, ...

Many aquifers in California and around the world are being drained of their groundwater because of the combined impacts of excess pumping, shifts in land use, and climate change. However, a new study by scientists at UC Santa Cruz and UC Berkeley, published on Oct. 18 in Nature Water, may offer a solution. It describes the development and operation of a novel incentive program that uses water rebates to pay for some of the costs of getting stormwater runoff into the ground. The program is called recharge net metering (ReNeM). Although ...

In vitro fertilization (IVF) is a time-intensive and often stress-inducing fertility procedure. Yet how does that stress impact its success? Investigators at Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, assessed the effects of anxiety and depression in men on fertility and IVF outcomes. Their findings reveal no correlation between anxiety, regardless of antidepressant use, on IVF outcomes or live birth rate. Results are published in Human Reproduction. “Our findings indicate that despite past concerns over antidepressant medication’s ...

Niigata, Japan - A new Japanese ecological study revealed that prefecture-specific participation rates for Specific Health Checkups (SHC participation rates) had significant negative effects on prefecture-specific standardized incidence rates (SIRs) of treated ESKD and prefecture-specific prevalence of chronic kidney disease (CKD). The findings support the importance of increasing SHC participation rates at the population level and encouraging people to undergo regular health checkups. "Japan has one of the highest incidence and ...

A 2000-year-old practice by Chinese herbalists – examining the human tongue for signs of disease – is now being embraced by computer scientists using machine learning and artificial intelligence. Tongue diagnostic systems are fast gaining traction due to an increase in remote health monitoring worldwide, and a study by Iraqi and Australian researchers provides more evidence of the increasing accuracy of this technology to detect disease. Engineers from Middle Technical University (MTU) in Baghdad and the University of South Australia (UniSA) used a USB web camera and computer to capture tongue ...

Two widely used statins, rosuvastatin and atorvastatin, are equally effective at preventing heart attacks, strokes and death in people with coronary artery disease. But while rosuvastatin treatment is associated with lower cholesterol levels, it also carries a higher risk of developing type 2 diabetes than atorvastatin, finds a study published by The BMJ today.  Lowering “bad” (LDL) cholesterol levels with statins is recommended for people with coronary artery disease - a condition where the blood vessels supplying the heart are ...

Surgery to straighten a crooked septum (the thin wall of bone and cartilage dividing the space between the two nostrils) is more effective than nasal sprays, and should be offered to adults with at least moderate symptoms such as breathing disruption, suggests a UK trial published by The BMJ today. A crooked (deviated) septum often means that one nasal passage is narrower than the other, making it feel blocked, which can affect breathing, sleep or exercising. Surgery to correct this (septoplasty) is a common operation. In 2019-20, 16,700 septoplasties were carried ...

  Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a University of Otago study showing they are still harmful to fish.   Petroleum-derived microplastics are known to impact marine life, but little is known about the impact of biodegradable alternatives.   The study, published in Science of the Total Environment and funded by a University of Otago Research Grant, is the first to assess the impact petroleum-derived plastic and biodegradable plastic have on wild fish.   Lead author Ashleigh Hawke, who completed a Master of Science in Otago’s Department of Marine Science, ...
