Quantum computers are better at guessing, new study demonstrates

Daniel Lidar, the Viterbi Professor of Engineering at USC and Director of the USC Center for Quantum Information Science & Technology, and first author Dr. Bibek Pokharel, a Research Scientist at IBM Quantum, achieved this quantum speedup advantage in the context of a “bitstring guessing game.”  They managed strings up to 26 bits long, significantly larger than previously possible, by effectively suppressing errors typically seen at this scale. (A bit is a binary number that is either zero or one). Quantum computers promise to solve certain problems with an advantage that increases as the ...

New discoveries about where atherosclerotic plaques rupture can lead to preventive treatments

A common cause of myocardial infarction and stroke is the rupture of atherosclerotic plaques. The exact location of plaque ruptures has previously been unknown, but now researchers at Lund University have mapped this. The research team has also identified an enzyme, a marker, that they hope will help predict who is at risk of having a myocardial infarction or a stroke due to a ruptured atherosclerotic plaque.  In atherosclerosis , fat  is accumulated in the artery walls creating atherosclerotic ...

Webb Space Telescope detects universe’s most distant complex organic molecules

CHAMPAIGN, Ill. — Researchers have detected complex organic molecules in a galaxy more than 12 billion light-years away from Earth – the most distant galaxy in which these molecules are now known to exist. Thanks to the capabilities of the recently launched James Webb Space Telescope and careful analyses from the research team, a new study lends critical insight into the complex chemical interactions that occur in the first galaxies in the early universe. University of Illinois Urbana-Champaign astronomy and physics professor Joaquin Vieira and graduate student Kedar Phadke collaborated with researchers at Texas A&M ...

Climate justice: Global North owes $170 trillion for excessive CO2 emissions, says study

Industrialised nations responsible for excessive levels of carbon dioxide emissions could be liable to pay a total of $170 trillion in compensation or reparations by 2050 to ensure climate change targets are met, say researchers.  This money, which amounts to nearly $6 trillion per year or about 7% of annual global Gross Domestic Product (GDP), would be distributed as compensation to low-emitting countries that must decarbonise their economies far more rapidly than would otherwise be required.  Financial redress for the losses and damages that climate-vulnerable countries face due to the excessive CO2 emissions of others is seen as an increasingly important ...

Availability of LGBTQ mental health services for youth

About The Study: This survey study found that 28% of youth-serving U.S. mental health facilities offered LGBTQ-specific mental health services in 2020. Although some states had relatively high levels of LGBTQ service availability as a percentage of facilities, many of these states had few facilities available to children per capita. Public mental health facilities were less likely to offer LGBTQ-specific mental health services, a concern given that the cost of care is a barrier to services. The findings suggest a need to expand availability of LGBTQ services ...

Can exercise help counteract genetic risk of disease?

New research has revealed being active could lower the risk of type 2 diabetes, even in people with a high genetic risk of developing the medical condition. The University of Sydney-led study found higher levels of total physical activity, especially moderate- to vigorous-intensity physical activity, had a strong association with a lower risk of developing type 2 diabetes. The findings were published in the British Journal of Sports Medicine. The researchers say the study demonstrates higher levels of physical activity should be promoted as a major strategy for type 2 diabetes ...

Doctors test chest pain medication to treat hot flashes

Women have long searched for remedies for the bothersome hot flashes that often come with menopause.  In a novel investigation, researchers at UC San Francisco tested the benefits of continuously wearing a nitroglycerin patch – an established treatment for chest pain from coronary artery disease – for menopausal women experiencing at least seven hot flashes a day. Unlike most treatments for hot flashes that target brain mechanisms, nitroglycerin works on blood vessels throughout the body.  The results were mixed. While ...

Scientists expand understanding of limb evolution in earliest birds

The assembly of the volant bird body plan from the ancestral bulky dinosaurian condition is an enduring topic of evolutionary biology. The body plan of volant birds demonstrates a pronounced decrease in body size and proportionate elongation of the forelimbs. Given the scaling relationship between limb and body size, changes to the former were likely clouded by changes to the entire body size. Since changes to individual limb elements provides the direct basis for natural selection, they are essential to comprehending branch- and lineage-specific evolutionary patterns across the transition from terrestrial to ...

Tracing Chile’s indigenous roots through genetics and linguistics

How do today’s indigenous communities of South America trace back to the history of human migration and contact in the continent? An international team has worked to reconstruct the legacy of Chile’s largest indigenous community, the Mapuche, in a quest to strengthen their representation in the history of the continent. It appears the Mapuche long lived in relative isolation but do bear some influences from other populations of the Central Andes and the far south of Chile. South America was the last continent ...

Refining surge protector in crops could boost yields

Awash in a rowed sea of its brethren, a corn leaf relegated to the lowest rung of its stem spends much of a June afternoon doused in shade cast by the higher-ups. Then a gust begins pushing, pulling and twisting the waxy wings in concert, cracking a window to the fireball roiling 93 million miles away. It’s a prime, precious opportunity for photosynthesis to transform the sunlight into food. Unfortunately, the photosynthetic equivalent of a surge protector — one evolved to help plants mitigate damage driven by sudden spikes of high-intensity light — is slow to reset after so much time in the shade. The gust dissipates, the moment ...
