A Northern Michigan University-led research project focusing on bobcats found evidence that human activity can exert a greater impact than environmental factors on carnivore predator-prey interactions, daily activity patterns and movement. The findings were recently published in Biodiversity and Conservation. Understanding that some animals perceive humans as "super predators" is critical for establishing successful wildlife management practices to promote functioning communities.

A giant Saguaro cactus that had lived for some 200 years was toppled by heavy rain in the southwestern US state of Arizona.

New potato varieties bred by the Texas A&M Potato Breeding Program could enter the french fry market before long, said Isabel Vales, Ph.D., Texas A&M AgriLife potato breeder in the Department of Horticultural Sciences in the Texas A&M College of Agriculture and Life Sciences.

Less than 500 miles from the North Pole, the Milne Fiord Epishelf Lake is a unique freshwater lake that floats atop the Arctic Ocean, held in place only by a coating of ice. The lake is dominated by single-celled organisms, notably cyanobacteria, that are frequently infected by unusual "giant viruses." Investigators from Université Laval, Québec, Canada have produced the first assessment of the abundance of the viruses in this lake. The research is published in Applied and Environmental Microbiology.

On its mission to the Moon, NASA's Orion spacecraft is designed to use NASA's Near Space Network and Deep Space Network to navigate. But if the craft loses communication with the ground or the Networks, crews can use a backup autonomous navigation system known as Optical Navigation (OpNav). This system analyzes images of the Moon or Earth taken from the spacecraft to determine its position relative to either of those two bodies.

Was there ever life on the moon? What about on other planets?

Sharing news articles with friends and followers on social media can prompt people to think they know more about the articles' topics than they actually do, according to a new study from researchers at The University of Texas at Austin.

Most posts in extremist online forums are made by a clique of particularly committed members, a major new study shows.

Engineers have repaired an issue affecting data from NASA's Voyager 1 spacecraft. Earlier this year, the probe's attitude articulation and control system (AACS), which keeps Voyager 1's antenna pointed at Earth, began sending garbled information about its health and activities to mission controllers, despite operating normally. The rest of the probe also appeared healthy as it continued to gather and return science data.

A University of British Columbia research team has developed a new, fast, efficient process for producing cancer-fighting immune cells in the lab. The discovery could help transform the field of immune cell therapy from an expensive, niche endeavor to something easily scalable and broadly applicable.

The James Webb space telescope has revealed dazzling new detail of a previously known slice of the cosmos 32 million light-years away, in a new picture released by NASA and the European Space Agency (ESA).

Terrorism became a more important issue for voters during the 2017 General Election because of the Manchester bombing, a new study shows.

NASA is preparing for their "Armageddon"-like mission of crashing a spacecraft into an asteroid, and they want the public to watch live.

Danielle, Earl, and Fiona have been patiently waiting their turn. Now there are signs they may come alive, possibly disrupting Labor Day weekend.

Last month, the U.S. General Accountability Office publicly released findings of an analysis showing that more than a third of public-school students still attend schools that are largely segregated.

Some Black students dream of going to them, following in the footsteps of sisters, brothers, mothers, fathers and trailblazers whose names have been etched into history.

Kidney disease affects one in nine adults globally and the incidence of kidney failure is steadily rising around the world. Being able to grow working kidney tissue in a laboratory could help accelerate medical treatments for kidney disease and restore kidney function. The kidney forms normally in humans as a result of two building blocks—metanephric mesenchyme and ureteric bud. The laboratory of Joseph Bonventre, MD, Ph.D., Chief of the Renal Unit and Founding Chief of the Engineering in Medicine Division at the Brigham... Читать дальше...

New research by a Northeastern engineering professor used recent storms and the COVID-19 pandemic to predict human movement during disasters in anticipation of more effective emergency response.

During the first COVID-19 wave, when Saumitra Das and colleagues were sequencing thousands of samples every day to check for SARS-CoV-2 variants as part of INSACOG, the Government of India's genome surveillance initiative, they were racing against time to track mutations as they appeared. "If we wanted to predict whether one of these mutations was going to be dangerous from a public health perspective, we needed an assay system," says Das, Professor at the Department of Microbiology and Cell Biology (MCB), Indian Institute of Science (IISc).

This study is led by Kefeng Zhu (Nanjing Joint Institute for Atmospheric Sciences) and Prof. Ming Xue (Key Laboratory for Mesoscale Severe Weather and School of Atmospheric Science, Nanjing University and Center for Analysis and Prediction of Storms and School of Meteorology University of Oklahoma).

Baker's yeast, Saccharomyces cerevisiae, has been extensively engineered to produce a vast variety of chemicals that are not naturally produced by yeast, including the important monomer for synthetic rubber, isoprene. However, all organisms are naturally evolved for better survival rather than maximized biosynthesis of products of human interest. S. cerevisiae is not an exception. Impaired cell growth was observed during its engineering by pathway compartmentation for improved isoprene biosynthesis.

Researchers from the Institute of Physics at the Nicolaus Copernicus University participated in research into the intensities of the overtone lines. Teams from the National Institute of Standards and Technology in the U.S. and the Physikalisch-Technische Bundesanstalt (PTB) in Germany also conducted their measurements. Theoretical calculations were carried out by a group from the University College London.

The COVID-19 pandemic offered a unique opportunity for climate change experts to relate sea level rise to the general public.

Having stronger religious beliefs is linked to higher levels of sexual satisfaction, a new study shows.

This study is led by Dr. Chen Jianfang and Dr. Li Hongliang from the Second Institute of Oceanography, Ministry of Natural Resources. Based on the field observation though two Chinese National Arctic Research Expedition (CHINARE) cruises in 2003 and 2008, the team focused the N/P uptake ratio by phytoplankton, seasonal consumption of nutrients, and export of particulate nitrogen in the Chukchi shelf and slope. Accordingly, they highlighted the overlooked contribution of the biological pump to the Pacific Arctic nitrogen deficit.
