Telescopio Gemini Norte ayuda a explicar por qué Urano y Neptuno tienen distintos colores

Los astrónomos ahora pueden saber por qué motivo Urano y Neptuno tienen distintos colores. Mediante observaciones del telescopio de Gemini Norte, las Instalaciones del Telescopio Infrarrojo de la NASA y el Telescopio Espacial Hubble, los científicos han desarrollado un modelo atmosférico único que coincide con las observaciones en ambos planetas y que revela que el exceso de neblina en Urano se acumula en la atmósfera inactiva y estática del planeta hace que se vea de un tono más claro que el de Neptuno.

New UCI-led study finds that your genetic sex determines the way your muscle “talks” to other tissues in your body

A new University of California, Irvine-led study identifies sex-specific circuits of muscle signaling to other tissues and that the organs and processes muscle impacts are markedly different between males and females. This new discovery provides insight into how muscle functions, such as exercise, promote healthy longevity, metabolism and improve cognition.

Gemini North Telescope Helps Explain Why Uranus and Neptune Are Different Colors

Astronomers may now understand why the similar planets Uranus and Neptune are different colors. Using observations from the Gemini North telescope, the NASA Infrared Telescope Facility, and the Hubble Space Telescope, researchers have developed a single atmospheric model that matches observations of both planets. The model reveals that excess haze on Uranus builds up in the planet’s stagnant, sluggish atmosphere and makes it appear a lighter tone than Neptune.

6 skin biopsy wound care tips from dermatologists

Skin cancer is the most common form of cancer. It is estimated that one in five Americans will develop skin cancer in their lifetime. As Skin Cancer Awareness Month continues, it’s important to check your skin regularly, and if you notice a spot on your skin that is different from others or that changes, itches, or bleeds, make an appointment to see a board-certified dermatologist.

Americans More Likely to Seek Surgical Care During a Pandemic if They and Hospital Staff are Vaccinated

Americans are more likely to have surgery during a pandemic such as COVID-19 if they are vaccinated, the hospital staff are vaccinated, the surgery is urgent or lifesaving (as opposed to elective), and the surgery is outpatient (i.e., not requiring an overnight stay), according to a new study published in Vaccine.

U.S. baby formula market broken, heavily regulated, WVU global supply chain expert says

As store shelves remain largely barren of baby formula, a West Virginia University researcher said he believes the domestic shortage could have been prevented with proper supply chain planning. John Saldanha, Sears chair in global supply chain management and associate professor at the John Chambers…

University of Kentucky Study: Asymptomatic COVID-19 Could Still Cause Pregnancy Risks

According to a new University of Kentucky College of Medicine study, asymptomatic COVID-19 infection during pregnancy could still have potential long-term consequences for a developing baby.

The study led by Ilhem Messoudi, Ph.D., chair of the Department of Microbiology, Immunology and Molecular Genetics, was published in Cell Reports May 25.

The research shows that COVID-19 infection in pregnant mothers who were asymptomatic or had mild symptoms still triggered immune responses causing inflammation in the placenta.

The space between us

Tree beta diversity — a measure of site-to-site variation in the composition of species present within a given area — matters more for ecosystem functioning than other components of biodiversity at larger scales. The finding has implications for conservation planning.

UCLA neuroscientists use electrical stimulation to restore breathing in surgery patients undergoing opioid-based anesthesia

New UCLA research published in The Journal of Physiology points to a novel treatment for respiratory depression associated with opioid use that administers electrical pulses to the back of the neck, helping patients regain respiratory control following high dosage opioid use. This could offer an alternative to pharmacological treatments, which can cause withdrawal symptoms, heart problems and can negatively affect the central nervous system.

Solar-Biomass Hybrid System Satisfies Home Heating Requirements in Winter

In Journal of Renewable and Sustainable Energy, researchers in China and the United States outline a computer simulation model addressing the challenge of solar power’s inherent intermittency by adding biomass as another renewable energy source to advance a reliable, affordable heating solution while reducing carbon dioxide emissions. The proposed solar-biomass hybrid system is based on distributed multi-generation technology that integrates photovoltaic-thermal and biomass power sources.

Urban Magnetic Fields Reveal Clues about Energy Efficiency, Pollution

In Journal of Applied Physics, researchers from the United States and Germany present a comparative analysis of urban magnetic fields between two U.S. cities: Berkeley, California, and the Brooklyn borough of New York City. They explore what kinds of information can be extracted using data from magnetic field sensors to understand the working of cities and provide insights that may be crucial for preventative studies.

COVID-19 Superspreader Events Originate from Small Number of Carriers

In Physics of Fluids, researchers create a model to connect what biologists have learned about COVID-19 superspreading with how such events have occurred in the real world. They use occupancy data to test several features ranging from viral loads to the occupancy and ventilation of social contact settings. They found that 80% of infections occurring at superspreading events arose from only 4% of those who were carrying the virus into the event. The top feature driving the wide variability in superspreading events was the number of viral particles found in index cases.
