El revestimiento a base de tiza crea un tejido refrigerante

En el calor abrasador del verano, cualquier persona que pase tiempo afuera podría beneficiarse de un tejido refrigerante. Pero ahora, los investigadores han innovado con un revestimiento de microescala a base de tiza que enfría el aire debajo del tejido tratado hasta 13 grados Celsius. Presentarán sus resultados en la ACS Fall 2024.

Previously Overlooked Algae Toxin Widespread in Southern Indian River Lagoon

Pseudo-nitzschia spp., an algae that produces the neurotoxin domoic acid, can bioaccumulate within food webs causing harm to humans and animals. A molecular study of Florida’s Indian River Lagoon shows this algae was present in 87 percent of the water samples collected. All isolates showed toxicity, and domoic acid was found in 47 percent of surface water samples. As a nursery for many organisms that supports a high amount of biodiversity, the presence of domoic acid could negatively impact the lagoon system.

Expert available to discuss new report that puts globe on course for breaching benchmark high temperature

A new report from the World Meteorological Organization (WMO) shows that the world’s average temperature could breach a record 1.5 Celsius of warming compared to pre-Industrial Revolution levels. News reports call the WMO announcement a critical warning of an average world temperature limit in the face of climate. Researchers indicate the threshold could be broken as early as 2027.

Hummingbirds use torpor in varying ways to survive cold temps

Hummingbirds have the fastest metabolism of any animal. The tropical hummingbirds that live in the Andes Mountains in South America must expend considerable energy to maintain their high body temperatures in cold environments. One tool that they use to survive cold nights is called torpor, a hibernation-like state that allows them to ramp down energy consumption to well below what they normally use during the day.

Coldest Northern Hemisphere temperature, first recorded by UW–Madison, officially confirmed

Nearly 30 years after recording a temperature of minus 93.2 degrees Fahrenheit (minus 69.6 Celsius) in Greenland, the measurement has been verified by the World Meteorological Organization as the coldest recorded temperature in the Northern Hemisphere. The measurement was first recorded by a University of Wisconsin–Madison Antarctic Meteorological Research Center Automatic Weather Station in December 1991.

Rutgers Climatologist Can Discuss Role of Snow in Climate System

New Brunswick, N.J. (June 15, 2020) – Rutgers University–New Brunswick Professor David A. Robinson is available for interviews on the role of snow in the climate system, snow variability and the extent of snow cover during the satellite era. “The extent of snow on…

Rutgers Expert Can Discuss Cool, Dry May With Snow and ‘Endless Spring’

New Brunswick, N.J. (June 10, 2020) – Rutgers University–New Brunswick climatologist David A. Robinson is available for interviews on the unusually cool May in New Jersey, including  the first measurable May snow in the Garden State since 1977. While many people remark…

Rutgers Expert Can Discuss Family’s 43-Year Backyard Bird Citizen Science Project

New Brunswick, N.J. (June 8, 2020) – Rutgers University–New Brunswick Professor Kimberly Russell is available for interviews on an upstate New York family’s 43-year family tradition – a competition to predict the arrival of American robins in their backyard every spring…

Toward a low-cost, low-power wearable sensor for temperature and respiration

Engineers at the University of California San Diego are developing low-cost, low-power wearable sensors that can measure temperature and respiration–key vital signs used to monitor COVID-19. The devices would transmit data wirelessly to a smartphone, and could be used to monitor patients for viral infections that affect temperature and respiration in real time. The research team plans to develop a device and a manufacturing process in just 12 months.

Physicists test coronavirus particles against temperature, humidity

One of the biggest unknowns about coronavirus is how changing seasons will affect its spread. Physicists from the University of Utah have received a NSF grant to create individual coronavirus particles without a genome. They’ll test how the structure of the coronavirus withstands changes in humidity and temperature.

Global Cooling After Nuclear War Would Harm Ocean Life

A nuclear war that cooled Earth could worsen the impact of ocean acidification on corals, clams, oysters and other marine life with shells or skeletons, according to the first study of its kind.

New Portable Tool Analyzes Microbes in the Environment

Imagine a device that could swiftly analyze microbes in oceans and other aquatic environments, revealing the health of these organisms – too tiny to be seen by the naked eye – and their response to threats to their ecosystems. Rutgers researchers have created just such a tool, a portable device that could be used to assess microbes, screen for antibiotic-resistant bacteria and analyze algae that live in coral reefs. Their work is published in the journal Scientific Reports.
