Russians, American delayed in space to return in September

Two cosmonauts and an astronaut who were supposed to leave the International Space Station this month will be brought back to Earth in late September, doubling their time aboard the orbiting laboratory to more than a year, Russia's space agency announced Friday.

Helping plants grow as phosphorus levels in soil deplete

Phosphorus is a natural mineral that is essential for plant growth and development, and Earth's agricultural-grade phosphorus reserves are expected to be depleted in 50 to 100 years. A new discovery by researchers at Michigan State University and the Carnegie Institution for Science is changing their understanding of iron toxicity in plants caused by low phosphorus levels.

New index helps identify 55 unprotected marine protected areas

A new Paper Park Index (PPI) developed by researchers at the University of British Columbia's Sea Around Us initiative helped identify 55 marine protected areas (MPAs) across the world where enough fishing takes place to contravene the protection status officially assigned to such sites.

11 ways to improve airlines for customers

The name of the game is customer satisfaction, especially in the airline industry where companies are constantly jockeying for business by promising better service than their competitors. Now a professor at the University of Missouri has used artificial intelligence to sort through thousands of customer reviews and identify where airlines are falling short.

Improving remote operation of planetary ground robots during upcoming Mars analog mission

The Institute for Systems and Robotics and the Interactive Technologies Institute, both represented by the Laboratory of Robotics and Engineering Systems (LARSyS), are proud to announce their participation in the upcoming AMADEE-24 mission to Mars. The mission, organized by the Austrian Space Forum (OeWF), aims to advance the development of space exploration through international collaboration and...

NASA prepares for historic asteroid sample delivery on Sept. 24

NASA's OSIRIS-REx spacecraft is cruising back to Earth with a sample it collected from the rocky surface of asteroid Bennu. When its sample capsule parachutes down into the Utah desert on Sept. 24, OSIRIS-REx will become the United States' first-ever mission to return an asteroid sample to Earth.

Providing help with integrated weed management

Pesticide use must be reduced. The EU has set a target to reduce pesticide use by 50% by 2030. Therefore, a strong focus on integrated weed management must be maintained in the coming years. When it comes to weeds, the focus has mainly been on improving the efficacy of pesticides, replacing or complementing them with mechanical treatments in the field.

Using high-precision quantum chemistry to study super-efficient energy transfer in photosynthesis

Photosynthesis drives all life on Earth. Complex processes are required for the sunlight-powered conversion of carbon dioxide and water to energy-rich sugar and oxygen. These processes are driven by two protein complexes, photosystems I and II. In photosystem I, sunlight is used with an efficiency of almost 100%. Here a complex network of 288 chlorophylls plays the decisive role.

Fly around Jezero Crater on Mars in this new video

There's a reason Jezero Crater was chosen as the landing site for the Perseverance Rover: it is considered one of the likeliest places to find any evidence if Mars was ever habitable for long periods of time. In this great new flyby video from ESA, you can get a birds-eye look at Perseverance's home.

Examining emotional intelligence in the context of virtual teams

Research from a team in India published in the International Journal of Public Sector Performance Management looks at the notion of "emotional intelligence" in the context of virtual teams. While it demonstrates an obvious relationship, the literature is still in the nascent stage and so precludes solid conclusions.

Protecting little brown bats from white-nose syndrome

In a new study, researchers have found that little brown bats suffering from white-nose syndrome (WNS) greatly increased their foraging activity at artificial bug buffets. The buffets, located near hibernation sites, will help bats to increase their fat reserves before and after hibernation. This should help them to survive the disease.
