Quantum information is a powerful technology for increasing the amount of information that can be processed and communicated securely. Using quantum entanglement to securely distribute a secret quantum state among multiple parties is known as “quantum state sharing.” An important protocol in quantum networks and cryptography, quantum state sharing works like this (in simple terms): a secret quantum state is divided into n shares and given to n players. The secret state can only be reconstructed ...

According to the U.S. Surgeon General, women should not drink alcoholic beverages during pregnancy because of the risk of birth defects in their unborn child. Now, research at Texas A&M University demonstrates that a father’s alcohol consumption before conception also links to growth defects that affect the development of his offspring’s brain, skull and face.  Research investigating fetal alcohol syndrome (FAS) exclusively examines maternal alcohol exposure. However, because men drink more and are more likely to binge drink than women, Dr. Michael Golding, an associate ...

It’s extremely difficult to study the biological basis of psychiatric disorders, in part because researchers can’t easily collect brain cells from living people to study in the laboratory. Now, University of Utah Health scientists have developed a way around that. The researchers grew three-dimensional structures, called “organoids”, derived from blood cells donated by a patient with pediatric bipolar disorder and by several family members. The approach identified significant molecular changes linked to the psychiatric condition. The results, reported in Molecular Psychiatry, suggest that structural changes in the ...

Key takeaways: American College of Surgeons research published in JAMA Surgery reveals the complexities and variations that occurred in cancer reporting in the National Cancer Database (NCDB) because of the pandemic. The number of reported cancer cases in NCDB declined by 14.4% compared with prior years, representing more than 200,000 cancer cases that were not diagnosed and/or treated at accredited facilities. Research offers guidance to centers across the country on how to interpret data from 2020 and onwards. CHICAGO: New research from the American College of Surgeons (ACS) outlines significant ways that the COVID-19 pandemic destabilized usual patterns of cancer care as reported ...

MINNEAPOLIS – Studies have shown that Mexican Americans have worse outcomes after a stroke than non-Hispanic white Americans. A new study looks at whether the language Mexican American people speak is linked to how well they recover after a stroke. The study is published in the April 12, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. “Our study found that Mexican American people who spoke only Spanish had worse neurologic outcomes three months after having a stroke than Mexican American people who spoke only English or were bilingual,” said study author ...

Archaeological sites along the Libyan shoreline are at risk of being damaged or lost due to increasing coastal erosion, according to a study published April 12, 2023 in the open-access journal PLOS ONE by Kieran Westley and Julia Nikolaus of Ulster University, UK and colleagues. The Cyrenaican coast of Eastern Libya, stretching from the Gulf of Sirte to the current Egypt-Libya border, has a long history of human occupation back to the Palaeolithic era, and it therefore hosts numerous important and often ...

The death of a parent can affect the health and well-being of children and adolescents, including higher risk of depression. A study published in PLOS ONE by Dröfn Birgisdóttir at Lund University, Lund, Sweden and colleagues suggests poor family cohesion is associated with long-term psychological symptoms among bereaved youth. Parentally bereaved children are at increased risk for mental illness including depression, anxiety, suicide attempts, and self-injurious behaviors. However, the relationship ...

New research into ancient populations that resided on the Tibetan Plateau has found that dairy pastoralism was being practiced far earlier than previously thought and may have been key to long-term settlement of the region’s extreme environment.  Professor Michael Petraglia, Director of Griffith’s Australian Research Centre for Human Evolution, was part of the international research team that set out to understand how prehistoric populations adapted to the vast, agriculturally poor highlands of the Tibetan Plateau.  The research, ...

Diffuse intrinsic pontine glioma (DIPG) is a lethal pediatric brain cancer that often kills within a year of diagnosis. Surgery is almost impossible because of the tumors’ location. Chemotherapy has debilitating side effects. New treatment options are desperately needed. Cold Spring Harbor Laboratory Professor Adrian Krainer is best known for his groundbreaking research on antisense oligonucleotides (ASOs)—molecules that can control protein levels in cells. His efforts led to Spinraza®, ...

The Tibetan Plateau, known as the “third pole”, or “roof of the world”, is one of the most inhospitable environments on Earth. While positive natural selection at several genomic loci enabled early Tibetans to better adapt to high elevations, obtaining sufficient food from the resource-poor highlands would have remained a challenge.  Now, a new study in the journal Science Advances reveals that dairy was a key component of early human diets on the Tibetan Plateau. The study reports ancient ...

Researchers from North Carolina State University have developed an electronic patch that can be applied to the leaves of plants to monitor crops for different pathogens – such as viral and fungal infections – and stresses such as drought or salinity. In testing, the researchers found the patch was able to detect a viral infection in tomatoes more than a week before growers would be able to detect any visible symptoms of disease. “This is important because the earlier growers can identify plant diseases or fungal infections, the ...

Simulated volcanic eruptions may be blowing up our ability to predict near-term climate, according to a new study published in Science Advances.  The research, led by the National Center for Atmospheric Research (NCAR), finds that the way volcanic eruptions are represented in climate models may be masking the models’ ability to accurately predict variations in sea surface temperatures in the tropical Pacific that unfold over multiple years to a decade.  These decadal variations in sea surface ...

Key Points Many federal and local government agencies send out a United States Department of Agriculture survey once a year or less to determine whether households experienced food insecurity in the last 12 months. In a new study, USC researchers found that households are more likely to accurately report food insecurity when surveyed more often and asked about their recent experiences. They also found that the USDA measure may be underreporting the true rate by as much as one-third.  Without ...

ITHACA, N.Y. – Can humans endure long-term living in deep space? The answer is a lukewarm maybe, according to a new theory describing the complexity of maintaining gravity and oxygen, obtaining water, developing agriculture and handling waste far from Earth. Dubbed the Pancosmorio theory – a word coined to mean “all world limit” – it was described in a paper published in Frontiers in Astronomy and Space Sciences. “For humans to sustain themselves and all of their technology, infrastructure and society in space, they need a ...

Permanent magnets, the kind found on refrigerators everywhere, exist because their constituent atoms behave as miniature magnets. They align and combine to form the larger magnet in a phenomenon called ferromagnetism. There are some materials where the atomic magnets instead form an alternating pattern, so the material has no net magnetization. Such antiferromagnets have attracted attention for their potential to create faster and more compact magnetic memory devices for computing. Realizing the full potential of antiferromagnetic devices will require sensing their atom-to-atom magnetic patterns, ...

DETROIT (April 12, 2023) – Henry Ford Hospital structural heart interventional cardiologists Pedro Villablanca, M.D., and Brian O’Neill, M.D., are the first in the U.S. to successfully implant the new transcatheter tricuspid valve replacement device LuX-Valve Plus™ for the treatment of patients with symptomatic tricuspid valve disease for whom traditional open-heart surgery is too high of a risk. “These are patients with severe tricuspid regurgitation who have no other options available to them in the U.S., based on the anatomy of their native valve and medical complexities,” ...

Dynamic control of terahertz (THz) waves at-will with an ultracompact device is important for THz technologies in biomedical imaging, telecommunications, detection, and beyond. However, tunable THz devices made of conventional materials are usually bulky, and they tend to have limited modulation depths and functionalities, due to weak interactions between naturally existing materials and THz waves. Metasurfaces – functional materials endowed with unparalleled flexibility to manipulate light at the deep-subwavelength scale – provide ...
