A new subtype of diabetes has been identified in children and young people in sub-Saharan Africa and could mean many patients are not on the best treatment for them.   The new finding, published in The Lancet Diabetes & Endocrinology and funded by the UK’s National Institute for Health and Care Research (NIHR), challenges the global understanding of diabetes in young people. It raises concerns that many patients across the continent, and possibly beyond, may need their diagnosis updated to access the best treatment. The discovery was made through the largest study of its kind in the region. Researchers found that nearly two thirds (65 per cent) of young ...

An international team of researchers has made a key discovery: many children and young adults in Sub-Saharan Africa diagnosed with type 1 diabetes (T1D) may have a different form of the disease - one not caused by the immune system, unlike classic T1D. This discovery could change how diabetes is diagnosed, treated and managed across the region, paving the way for more accurate care and better outcomes. The research was published today in Lancet Diabetes and Endocrinology. “This is the first study across several Sub-Saharan African countries to use the same lab tests and genetic tools to learn more about type 1 diabetes. We've done similar research in the U.S. with different groups, ...

(Santa Barbara, Calif.) — Rare earth elements sustain the Information Age, and securing a supply of these metals has become a matter of national and economic security. They’re ubiquitous in our smart technologies, high performance materials and industrial catalysts. Yet reclaiming them is complex, dangerous and expensive. That’s why UC Santa Barbara’s Justin Wilson has partnered with the mineral recovery company REEGen. “We’ve developed a new approach to extract rare earth elements from end-of-life products like electronic waste from phones, batteries and discarded catalytic converters,” said Wilson, a professor in UCSB’s Department ...

Lunar dust is more than a mild irritant or hallmark of an untidy room like dust found on Earth. Lunar dust particles are sharp and abrasive due to the lack of atmosphere gradually dulling their surfaces, leading them to potentially damaging critical lunar equipment or causing respiratory issues for astronauts. Managing lunar dust (also known as regolith) and safeguarding astronauts or sensitive equipment on the moon isn’t as simple as sweeping it up with a broom and pan. That’s why a team of NASA-funded UCF researchers is pioneering a new nanocoating to passively mitigate the effects of lunar dust, ...

Around 10 million people globally live with the life-threatening virus HTLV-1. Yet it remains a poorly understood disease that currently has no preventative treatments and no cure. But a landmark study co-led by Australian researchers could change this, after finding existing HIV drugs can suppress transmission of the HTLV-1 virus in mice. The study, published in Cell, could lead to the first treatments to prevent the spread of this virus that is endemic among many First Nations communities around the world, including in Central Australia. The research by WEHI and the Peter Doherty Institute for Infection and Immunity ...

Organic thermoelectric devices (OTEs) convert waste heat into useful electric power, but they are not yet efficient enough for practical use. KAUST researchers have now developed a tool that predicts the best solvent to use when processing the devices’ polymer films, significantly improving their power output[1]. “Waste heat is present everywhere: industrial processes, car engines, air conditioners, and even in your cup of coffee, so it would be useful to recover a portion of this energy into electricity,” says ...

People are diverse, and the environments they live in may influence them differently. This broad diversity increases the need for neuroimaging studies that collect data from large communities. In a new eNeuro paper, Tara Thiagarajan, from Sapiens Labs, and colleagues showcase the feasibility of going to low- and middle-income communities and collecting large-scale, high-quality data.  In their paper, the authors share the methods they used to create two ongoing data acquisition programs in India and Tanzania. These programs provide nonspecialist training, structured teams, and automated data ...

In a new JNeurosci paper, Julie Royo, from the Institute of Cerveau, and colleagues explored the neuroanatomy that underlies social dominance in nonhuman primates.  The researchers focused on brain tracts associated with human emotion, motivation, and memory as they assessed structural brain properties and behavioral measures of social dominance in 15 squirrel monkeys. These behavioral measures were related to hierarchy, aggression, and submission. Royo and colleagues found that one of the brain tracts they focused on—the uncinate fasciculus—highly correlated with their social dominance measures. This correlation was particularly true for the uncinate fasciculus ...

Betelgeuse is one of the brightest stars in the night sky, and the closest red supergiant to Earth. It has an enormous volume, spanning a radius around 700 times that of the Sun. Despite only being ten million years old, which is considered young by astronomy standards, it’s late in its life. Located in the shoulder of the constellation Orion, people have observed Betelgeuse with the naked eye for millennia, noticing that the star changes in brightness over time. Astronomers established that Betelgeuse has a main period of variability of around 400 days and a more extended secondary period of around six years. In 2019 and 2020, ...

Hollow, pumpkin-shaped molecules can efficiently separate valuable hydrocarbons from crude oil, KAUST researchers have shown[1]. These ‘molecular sieves’, known as cucurbiturils, could enable a more sustainable approach to producing raw materials for the chemicals industry. Crude oil is a complex mixture of hydrocarbons vital for almost every aspect of life, from fuels to plastics. Cyclohexane, for example, is used in nylon production, but isolating it at sufficient purity typically involves multiple energy-intensive fractional distillation steps. The KAUST team has now developed an alternative separation strategy based on cucurbiturils, named for their ...

Near-infrared (NIR) spectroscopy is a powerful technique for probing molecular compositions and structures non-invasively. However, traditional NIR spectrometers are often bulky and expensive, limiting their applications in portable or resource-constrained settings. A team of researchers from Huazhong University of Science and Technology (HUST) has addressed this challenge by developing a miniaturized NIR computational spectrometer using PbS quantum dots (QDs). Their work, published in Nano Research, demonstrates how finely-tuned QDs can achieve a spectral resolution of 1.5 nm, a significant improvement over previous works. Why is this study important? NIR ...

The efficacy of CAR-T cells in ablating solid tumors is significantly impeded by the densely packed tumor extracellular matrix (ECM). This physical barrier severely restricts CAR-T cell infiltration within the tumor, thereby inhibiting their immunogenicity and antitumor response. While combining CAR-T with hyaluronidase (HAase) to reduce ECM is apparent, the efficacy is limited because of low accumulation and penetration efficiency of HAase inside the tumor tissue.   A team of material scientists led by Xuesi Chen from Key Laboratory of Polymer Ecomaterials at Changchun Institute of Applied Chemistry ...
