Engineers at the University of California San Diego have developed a simple, low-cost clip that uses a smartphone's camera and flash to monitor blood pressure at the user’s fingertip. The clip works with a custom smartphone app and currently costs about 80 cents to make. The researchers estimate that the cost could be as low as 10 cents apiece when manufactured at scale. The technology was published May 29 in Scientific Reports. Researchers say it could help make regular blood pressure monitoring easy, affordable and accessible to people in resource-poor ...

Osaka, Japan – Researchers from the Department of Mechanical Science and Bioengineering at Osaka University have invented a new kind of walking robot that takes advantage of dynamic instability to navigate. By changing the flexibility of the couplings, the robot can be made to turn without the need for complex computational control systems. This work may assist the creation of rescue robots that are able to traverse uneven terrain. Most animals on Earth have evolved a robust locomotion system using legs that provides them with a high degree of mobility over a wide range of environments. Somewhat disappointingly, engineers who have attempted to replicate this ...

How do you diagnose and manage depression in adolescents? A new review published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.220966 aims to help primary care clinicians address this increasingly common, yet under-detected condition, in teenagers. "Although more than 40% of people with depression experience onset before adulthood, depression remains undetected in many adolescents in Canada, and most are untreated," writes Dr. Daphne Korczak, a psychiatrist with the Hospital for Sick Children (SickKids) and the University of Toronto, Toronto, Ontario, with coauthors. "Clinicians consistently ...

The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study from University of Illinois Urbana-Champaign Electrical and Computer Engineering researchers has found that the assumption of always perfect IQE is wrong: the IQE of an LED can be as low as 27.5%. This new research, “Low temperature absolute internal quantum efficiency of InGaN-based light-emitting diodes”, was recently published in Applied Physics Letters. As ECE associate professor Can Bayram puts it, LEDs are the ultimate lighting source. ...

Infections caused by fungi, such as Candida albicans, pose a significant global health risk due to their resistance to existing treatments, so much so that the World Health Organization has highlighted this as a priority issue. Although nanomaterials show promise as antifungal agents, current iterations lack the potency and specificity needed for quick and targeted treatment, leading to prolonged treatment times and potential off-target effects and drug resistance. Now, in a groundbreaking development with far-reaching implications for global ...

Earth’s magnetic field, generated by the flow of molten iron in the planet’s inner core, extends out into space and protects us from cosmic radiation emitted by the Sun. It is also, remarkably, used by animals like salmon, sea turtles and migratory birds for navigation.    But how? And why? A new study from researchers at Western’s Advanced Facility for Avian Research (AFAR), home to the world’s first hypobaric climatic wind tunnel for bird flight, explores a brain region called cluster N that migratory birds use to perceive Earth’s magnetic field. The team discovered the region is activated very ...

A new study from Swansea University and the University of Cape Town provides the first documented evidence of a cessation in urban space use by a female baboon after giving birth: another example of how wild animals are adaptively responding to urbanisation. The study, recently published in the journal Ecology & Evolution, used GPS collars to track the movements of 13 chacma baboons in Cape Town, South Africa. The data revealed that when one collared female gave birth, she stopped using urban space without any significant change in daily distance travelled or social interactions that would be expected with general risk-sensitive behaviour during this ...

Islands of trees in oil palm plantations can significantly increase biodiversity within five years without reducing productivity. This has been shown by an experiment, which has been running for over ten years in Indonesia as part of the Collaborative Research Centre (CRC) "EFForTS" at the University of Göttingen. An international team of researchers led by Göttingen planted experimental islands of trees in plantations on the island of Sumatra to counteract the species loss caused by the ...

For patients with solid cancers, endoscopic surgery is one of the primary treatment options to remove tumors. However, there is a high risk of cancer recurrence if even a small number of cancerous cells are left behind after surgical resection. To prevent this from happening, researchers developed fluorescence-guided surgery (FGS). In FGS, patients are injected with a fluorescent probe that preferentially binds to tumor cells, enabling surgeons to easily identify lesions with the help of specialized endoscopes that emit the necessary excitation light. Unfortunately, tumors can be highly heterogeneous, ...

Philadelphia, May 26, 2023—IgA deficiency is the most common primary immune deficiency worldwide, but its presentation has puzzled physcians and researchers. Some with the disorder present with symptoms like recurrent infections, autoimmune disease, or allergies, whereas others have no symptoms at all and only become aware of their IgA-deficient status through an incidental finding on a blood test. This variability has raised the question among researchers: Why aren’t many of those with IgA deficiency sicker? A new study by researchers at Children’s ...

HERSHEY, Pa. — The first protein-based nano-computing agent that functions as a circuit has been created by Penn State researchers. The milestone puts them one step closer to developing next-generation cell-based therapies to treat diseases like diabetes and cancer. Traditional synthetic biology approaches for cell-based therapies, such as ones that destroy cancer cells or encourage tissue regeneration after injury, rely on the expression or suppression of proteins that produce a desired action within a cell. This approach can take time (for proteins ...

By 2050, one in 10 individuals are expected to live with some form of hearing loss. Of the hundreds of millions of cases of hearing loss affecting individuals worldwide, genetic hearing loss is often the most difficult to treat. While hearing aids and cochlear implants offer limited relief, no available treatment can reverse or prevent this group of genetic conditions, prompting scientists to evaluate gene therapies for alternative solutions. One of the most promising tools used in these therapies—adeno associated virus (AAV) vectors—has galvanized the hearing-loss community in recent years. ...

Sensory cells in the vagus nerve can detect and locate food in the esophagus. Their signals help transport the food onward to the stomach. Signal failure leads to swallowing disorders, say a team led by Carmen Birchmeier at the Max Delbrück Center. They have published their findings in “Neuron.” Swallowing disorders can have many causes, and they occur more frequently in older people. But neurological diseases such as multiple sclerosis and Parkinson’s disease, and certain medications, can also prevent food moving normally from mouth to stomach. Possible consequences include malnutrition, weight loss, and dehydration. Now a team led ...

Over thousands of years some animals have specialised to live in environments where the sun never shines: giant squid with eyes the size of volleyballs see even in the darkest depths while others, like cave-dwelling olms, have lost the functionality of their eyes completely. But for animals that do not live in these extremes, how do species manage a world that suddenly becomes dark? Lakes that become turbid from algal blooms, agricultural run-off, or other environmental pollutants represent common examples of environmental disturbances that can impact the visual scene that ...

Researchers at the Niels Bohr Institute have, collaborating with the University of Münster and Ruhr-Universität Bochum, developed new technology capable of processing the enormous amounts of information quantum systems generate. Deterministic single photon light sources, creating quantum bits at extreme rates and speed are now coupled to specially designed, integrated photonic circuits, capable of processing quantum information with adequate speed and quality without degrading the susceptible quantum states. This means that the first steps have been taken towards the development of photonic quantum devices that can, for example, ...

UPTON, NY—Physicists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) have published the first observation of directed flow of hypernuclei. These short-lived, rare nuclei contain at least one “hyperon” in addition to ordinary protons and neutrons. Hyperons contain at least one “strange” quark in place of one of the up or down quarks that make up ordinary nucleons (the collective name for protons and neutrons). Such strange matter is thought to be abundant in the hearts of neutron stars, which are among the densest, most exotic objects in the universe. While blasting off to neutron stars to study ...
