The new compact representation of fermions outperforms all previous representations improving memory use and algorithm size each by at least 25% - a significant step towards realising practical scientific applications on near-term quantum computers.

Emotions towards and cultural importance of large carnivores are better predictors of the acceptance of management strategies by local communities than the extent of livestock depredation. This is the result of an interdisciplinary investigation led by Leibniz Institute for Zoo and Wildlife Research. They conducted 100 questionnaires with Maasai pastoralists in Ngorongoro Conservation Area, focusing on three large carnivore species (spotted hyenas, lions and leopards) and three management strategies (no action, relocation and lethal control).

Scientists uncover new properties of plasma that have wide potential applications for astrophysical and fusion plasmas.

Patients with kidney failure did not report better experience with care from more frequent face-to-face visits with kidney specialists at dialysis facilities. In fact, more frequent visits were linked with slightly lower patient-reported experiences with kidney-related care.

A single tree along a city street or in a backyard can provide measurable cooling benefits, according to a new study from American University.

A research team from the University of Göttingen and the University of British Columbia (Canada) has investigated how people in five different countries react to various usages of genome editing in agriculture. The researchers looked at which uses are accepted and how the risks and benefits of the new breeding technologies are rated by people. The results show only minor differences between the countries studied - Germany, Italy, Canada, Austria and the USA.

Researchers from Boston University School of Medicine (BUSM) and ZabBio (San Diego, CA) have developed an anti-sperm monoclonal antibody, the Human Contraception Antibody (HCA), which they found to be safe and possess potent sperm agglutination (clumping) and immobilization activity in laboratory tests.

NOR-Solidarity, an independent, add-on, randomized controlled trial to the World Health Organization (WHO) Solidarity trial, found that neither remdesivir nor hydroxychloroquine (HCQ) affected viral clearance in hospitalized patients with COVID-19. The WHO Solidarity trial showed no effect of remdesivir or hydroxychloroquine (HCQ) on mortality but did not assess antiviral effects of these drugs. The findings are published in Annals of Internal Medicine.

For the first time, the long-theorized neutron-clustering effect in nuclear reactors has been demonstrated, which could improve reactor safety and create more accurate simulations, according to a new study recently published in the journal Nature Communications Physics.

The Black Lives Matter movement has brought increasing attention to disparities in how police officers treat Black and white Americans. Now, research published by the American Psychological Association finds that disparity may exist even in subtle differences in officers' tone of voice when they address Black and white drivers during routine traffic stops.

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new way to control and shape optical singularities. The technique can be used to engineer singularities of many shapes, far beyond simple curved or straight lines. It could be used for a wide range of applications from super resolution imaging to optical trapping.

Researchers from the National Institute of Information and Communications Technology (NICT), Network Research Institute, succeeded the first S, C and L-bands transmission over long-haul distances in a 4-core optical fiber with standard outer diameter (0.125 mm). The researchers constructed a transmission system that makes full use of wavelength division multiplexing technology by combining different amplifier technologies, to achieve a transmission demonstration with date-rate of 319 terabits per second, over a distance of 3,001 km.

It's a supply and demand problem, it's a transportation problem, it's a donor problem - and that just scratches the surface. According to the Organ Procurement and Transplantation Network, every 9 minutes a new patient is added to the organ waiting list. Every day 17 people die waiting for a kidney transplant. New research in the INFORMS journal Management Science tackles the transportation part of this problem.

The American Academy of Neurology (AAN), the world's largest association of neurologists with more than 36,000 members, is issuing ethical guidance for neurologists and neuroscience professionals who care for people with Alzheimer's disease and other dementias. The new position statement is published in the July 12, 2021 online issue of Neurology®, the medical journal of the American Academy of Neurology.

States that legalize recreational marijuana experience a short-term decline in opioid-related emergency department visits, particularly among 25- to 44-year-olds and men, according to an analysis led by the University of Pittsburgh Graduate School of Public Health. The study shows that even after the temporary decline wears off, recreational cannabis laws are not associated with increases in opioid-related emergency department visits.

Having a home near a busy airport certainly has its perks. It is close to many establishments and alleviates the problem of wading through endless traffic to catch flights. But it does come at a cost -- tolerating the jarring sounds of commercial airplanes during landing and takeoff. Researchers at Texas A&M University have conducted a computational study that validates using a shape-memory alloy to reduce the unpleasant plane noise produced during landing.

UC San Diego researchers discovered that immunotoxins targeting the protein mesothelin prevent liver cells from producing collagen, a precursor to fibrosis and cirrhosis, in mouse models of human disease.

Breakthrough paper reveals multiple mechanisms for wing transparency in butterflies and moths; shows that wing transparency has evolved multiple times in lepidopterans.

Two recently published innovations by University of Florida researchers at the Department of Energy's Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) demonstrated the first successful precision breeding of sugarcane by using CRISPR-Cas9 genome editing.The work gives researchers a targeted and efficient way to develop new sugarcane varieties with higher productivity, herbicide resistance, or more oil production - key to CABBI's goals to produce fuels and chemicals from plants instead of petroleum.

A study, published in the Proceedings of the National Academy of Sciences, sampled more than 1.5 million people in 269 U.S. counties and 37 European nations. Researchers found that those who grew up in areas with higher levels of atmospheric lead had less adaptive personalities in adulthood -- lower levels of conscientiousness and agreeableness and higher levels of neuroticism.
