Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a technique to observe how radiation damages molecules over time-frames of just one quadrillionth of a second — or a femtosecond. The technique involves dissolving organic molecules in water to simulate the state molecules are found in biological tissue. This allows the research team to

For children fearful of undergoing MRI scans, an inexpensive everyday item used as a marker, such as a jelly baby lolly or a plastic, fish-shaped soy sauce container, might make the process a little less intimidating. And thanks to a QUT study, these and other relatively cheap, common items have been shown to be visible,

A ground-breaking device to help patients with dizziness problems has moved a step forward following a successful research study. Researchers from UEA and the Norfolk and Norwich University Hospital (NNUH) have published the results of the biggest collection of continuous eye movement data after testing the effectiveness of a wearable diagnostic headset. The Continuous Ambulatory

A KAIST research team succeeded in visualizing pulmonary microcirculation and circulating cells in vivo with a custom-built 3D intravital lung microscopic imaging system. They found a type of leukocyte called neutrophils aggregate inside the capillaries during sepsis-induced acute lung injury (ALI), leading to disturbances and dead space in blood microcirculation. According to the researchers, this

Uterine fibroid embolization (UFE) effectively treats uterine fibroids with fewer post-procedure complications compared to myomectomy, according to new research presented today at the Society of Interventional Radiology’s 2019 Annual Scientific Meeting. Women who received this minimally-invasive treatment also had a slightly lower need for additional treatment than those who underwent surgery. UFE is a minimally-invasive

A team of researchers from New York University has engineered nanoscale protein micelles capable of both delivering chemotherapeutic drugs and of being tracked by magnetic resonance imaging (MRI). The innovation falls into the category of “theranostics,” meaning that it combines diagnostic capability and drug delivery, allowing researchers to administer therapy while also non-invasively monitoring the

When Katie New first suspected her son had autism, she had to wait 18 months for a diagnosis. She also had to travel nearly 100 miles from her hometown of Poplar Bluff, Missouri, to see an autism specialist in Cape Girardeau. When she had similar concerns regarding her younger child, she was able to get

Wearable devices are increasingly bought to track and measure health and sports performance: from the number of steps walked each day to a person’s metabolic efficiency, from the quality of brain function to the quantity of oxygen inhaled while asleep. But the truth is we know very little about how well these sensors and machines

Fluorescence-based biosensing and bioimaging technologies are widely used in research and clinical settings to detect and image various biological species of interest. While fluorescence-based detection and imaging techniques are convenient to use, they suffer from poor sensitivity. For example, when a patient carries low levels of antigens in the blood or urine, the fluorescent signal

The human body is an extremely complex molecular machine, the details of which can be followed through certain substances; so-called biomarkers. Unfortunately, it is not yet possible to monitor biomarkers live in patients when these are present in minuscule concentrations. Researchers at Eindhoven University of Technology have now developed a new technique that can become

The importance of the human brown adipose tissue (BAT) has become clearer during the past ten years. Using positron emission tomography, PET, it was shown that adult humans have functional BAT. Coldness is an effective activator of the BAT metabolic function but, in rodents, eating has the same effect. Now, the researchers at Turku PET

Purdue University researchers think the gap between a psychologists’ diagnosis and a patient’s self-evaluation might not be as extreme as previously perceived when both are using the same evaluation tools. The research findings are published in the Journal of Consulting and Clinical Psychology. They lessen concerns that people lack awareness of their own personality pathology.

The bombing of the Japanese cities Hiroshima and Nagasaki by the United States in 1945 was the first and only use of nuclear weapons against civilian targets. A series of studies began in its aftermath to measure the impact of the fallout, in terms of both the radiation dose to which the victims were exposed

It has been estimated that there are more than 10^100 possible materials that can be synthesised, grown, and optimised. Materials design can be a slow and laborious process and investigating the full parameter space is a formidable challenge. Machine learning and other advanced statistical techniques will almost certainly help accelerate materials discovery, design, and optimisation,
