Microdiamonds with nitrogen vacancy centers are increasingly used as biological tracers thanks to the optical fluorescence of NV centers. But the NV centers also can be spin-polarized by low-power lasers, and the polarized centers then polarize nearby carbon-13 atoms occurring naturally in the diamonds. These hyperpolarized C-13 atoms can be detected by NMR imaging. UC Berkeley chemists now demonstrate dual-mode imaging with NV-center diamonds, potentially allowing high-quality imaging 10 times deeper than with optics alone.

A new technology developed by UZH researchers enables the body to produce therapeutic agents on demand at the exact location where they are needed. The innovation could reduce the side effects of cancer therapy and may hold the solution to better delivery of Covid-related therapies directly to the lungs.

Scientists have detected new early-warning signals indicating that the central-western part of the Greenland Ice Sheet may undergo a critical transition relatively soon. Because of rising temperatures, a new study by researchers from Germany and Norway shows, the destabilization of the ice sheet has begun and the process of melting may escalate already at limited warming levels. A tipping of the ice sheet would substantially increase long-term global sea level rise.

Following the progression of breast cancer in an animal model revealed a path that transforms a slow-growing cancer type known as estrogen receptor (ER)+/HER2+ into a fast-growing ER-/HER2+ type that aggressively spreads or metastasizes to other organs.

Intact rainforests across tropical Africa continued to remove carbon from the atmosphere before and during the 2015-2016 El Niño, despite the extreme heat and drought. Theyl removed 1.1 billion tonnes of carbon dioxide per year from the atmosphere during the El Niño monitoring period. This rate is equivalent to three times the carbon dioxide emissions of the UK in 2019. Scientists were surprised by this discovery.

There are roughly 50 billion individual birds in the world, a new big data study by UNSW Sydney suggests - about six birds for every human on the planet.

A new open-access research collection published in Ecosphere reveals unexpected lessons drawn from decades of rich data from the Long Term Ecological Research (LTER) Network.

Researchers at Washington University School of Medicine in St. Louis have found that although the vast majority of people with alcohol use disorder see their doctors regularly for a range of issues, fewer than one in 10 ever get treatment to help curb their drinking.

Amid the rising toll of opioid overdoses and deaths in the U.S., several states are considering laws enabling civil commitment for involuntary treatment of patients with substance use disorders (SUDs). Most addiction medicine physicians support civil commitment for SUD treatment - but others strongly oppose this approach, reports a survey study in Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine (ASAM).

Mothers who are Hispanic or who come from rural or low socioeconomic status neighborhoods are less likely to have their child's critical heart condition diagnosed before birth, according to a new study in the journal Circulation.

The study establishes baseline observations for tropical birds in East Africa, filling in an important data gap for monitoring biodiversity and tropical ecosystem health in a warming world.

Insulin plays a critical role in the maturation, after injury, of immature olfactory sensory neurons. Applying insulin into the nasal passage could be developed as a therapy for injury caused by a host of issues.

Air quality standards recommended by the American Thoracic Society (ATS) have the potential to prevent more illness and death than standards adopted by the U.S. Environmental Protection Agency (EPA), according to research presented at the ATS 2021 International Conference.

A team of Welsh academics has developed a new method of supporting health professionals to make clinical decisions about people who may be at risk of taking their own lives.

Up to 38.6% of people with colon cancer who have a hereditary cancer syndrome--including 6.3% of those with Lynch syndrome--could have their conditions remain undetected with current universal tumor-screening methods, and at least 7.1% of people with colorectal cancer have an identifiable inherited genetic mutation, according to new data published by scientists at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

The American College of Cardiology's (ACC) Global Heart Attack Treatment Initiative (GHATI) had measurable positive impacts on care delivery for heart attacks in low- and middle-income countries, according to data from the program's first year. Results were presented at the ACC's 70th Annual Scientific Session.

Cardiologists at Beth Israel Deaconess Medical Center (BIDMC), designed the Safety Assessment of Femoropopliteal Endovascular Treatment With Paclitaxel-coated Devices (SAFE-PAD) study to provide the information necessary to make scientifically-sound regulatory decisions about the safety of these devices.

Medical devices employing AI stand to benefit everyone in society, but if left unchecked, the technologies could unintentionally perpetuate sex, gender and race biases.

An article recently published in the prestigious journal Nature Communications, written by University of Rhode Island College of Engineering Professor Stéphan Grilli and his colleagues, reveals new data on the Anak Krakatau volcano flank collapse, which was triggered by an eruption on December 22, 2018.

Two components of imagination -- constructing and evaluating imagined scenarios -- rely on separate subnetworks in the default mode network, according to research recently published in JNeurosci.
