Varroa destructor is a parasitic mite that affects honeybees. It originated in Asia, but has spread to almost every region of the world. Domestic honey bees, Apis mellifera, are particularly vulnerable to this parasite, which can cause the loss of a colony in just a few months, as well as significant economic losses for beekeepers. Although chemical treatments have existed since the 1980s, they...

Food production in the Netherlands is an economic success but has led to many environmental issues, including nitrogen pollution. Recently, the policy to allow economic growth while reducing nitrogen losses was disapproved by the highest court in the Netherlands, casting the country into a nitrogen crisis. In a new article in the sustainability science journal One Earth, Jan Willem Erisman...

Australia is sweltering through another heatwave, and there will be more in the near future as climate change brings hotter, drier weather. In some parts of Australia, the number of days above 40℃ will double by 2090, and with it the tragedy of more heat-related deaths.

For those of you who live in cities, ask yourself: What it is about your urban lifestyle that makes it worth it despite the pollution, the noise and the traffic? Perhaps it's the hundreds of unique restaurants that you like to dine at. Or the density that fosters a vibrant night life and cosmopolitan cultural scene. Maybe it's the parks, the museums, the tall buildings, the mass transit.

Due to the coronavirus pandemic, the world is in an unexpected moment of global uncertainty and change. Countries, cities and communities worldwide are moving through rotating economic lockdowns and stay-at-home orders. At this time, the divides and potential benefits of digital technology are ever more apparent.

The Singapore Zoo has welcomed a lion cub named Simba to its animal kingdom following artificial insemination that officials said Tuesday was a first for the city-state.

By 2020, massive losses of large populations of corals have been observed throughout Florida and into the greater Caribbean basin. Taking into account the high mortality and the large number of susceptible species affected, this is likely the most lethal case of Stony Coral Tissue Loss Disease (SCTLD) ever recorded in modern history.

New research from Queen Mary University of London and the University of Maryland, has reignited the debate around the behavior of the giant dinosaur Spinosaurus.

Social inequality was "recorded on the bones" of Cambridge's medieval residents, according to a new study of hundreds of human remains excavated from three very different burial sites within the historic city centre.

An elderly gorilla was recovering from a serious case of COVID-19 after he was treated with cutting-edge synthetic antibodies, the San Diego Zoo said Monday.

A major winter storm is threatening to blanket parts of the middle of the country with more than a foot of snow Monday, promising to disrupt travel and even forcing the closure of some coronavirus testing sites.

Massive earthquakes are, fortunately, rare events. But that scarcity of information blinds us in some ways to their risks, especially when it comes to determining the risk for a specific location or structure.

Research from North Carolina State University shows that extreme weather events, such as hurricanes and increased precipitation, affect both the amount and the composition of picophytoplankton in the Neuse River Estuary. The work is a first step in determining how a wetter climate may affect the estuarine ecosystem.

Every living organism has DNA, and every living organism engages in DNA replication, the process by which DNA makes an exact copy of itself during cell division. While it's a tried-and-true process, problems can arise.

A team led by plant biologists at the Universities of Freiburg and Göttingen in Germany has shown for the first time that mosses have a mechanism to protect them against cold that was previously known only in flowering plants. Professor Ralf Reski at the Cluster of Excellence Centre for Integrative Biological Signalling Studies (CIBSS) at the University of Freiburg and Professor Ivo Feussner at...

An extensive review of cephalopod fauna from the Northwest African Atlantic coast was performed by researchers from the University of Vigo (Spain) and the Spanish Institute of Oceanography (IEO). The study was based on the collections gathered in 1,247 bottom trawl stations carried out during ten multidisciplinary surveys in the Canary Current Large Marine Ecosystem (CCLME).

Scientists at the University of California, Irvine and NASA's Jet Propulsion Laboratory have for the first time quantified how warming coastal waters are impacting individual glaciers in Greenland's fjords. Their work is the subject of a study published recently in Science Advances.

Employees feel significantly less job distress if they work at companies that are open and transparent about the firm's finances, including budgets and profits, a new study found.

Quantum physics allows to make statements about the behavior of a wide variety of many-particle systems at the atomic level, from salt crystals to neutron stars. In quantum systems, many parameters do not have concrete values, but are distributed over various values with certain probabilities. Often this distribution takes the form of a simple Gaussian bell curve that is encountered also in...

When it launches in the mid-2020s, NASA's Nancy Grace Roman Space Telescope will explore an expansive range of infrared astrophysics topics. One eagerly anticipated survey will use a gravitational effect called microlensing to reveal thousands of worlds that are similar to the planets in our solar system. Now, a new study shows that the same survey will also unveil more extreme planets and...

Nature is full of color. For flowers, displaying color is primarily a means to attract pollinators. Insects use their color vision not only to locate the right flowers to feed on but also to find mates. The evolutionary interaction between insects and plants has created complex dependencies that can have surprising outcomes. Casper van der Kooi, a biologist at the University of Groningen, uses an...

X-rays are usually difficult to direct and guide. X-ray physicists at the University of Göttingen have developed a new method with which the X-rays can be emitted more precisely in one direction. To do this, the scientists use a structure of thin layers of materials with different densities of electrons to simultaneously deflect and focus the generated beams. The results of the study were...

Dairy producers know early nutrition for young calves has far-reaching impacts, both for the long-term health and productivity of the animals and for farm profitability. With the goal of increasing not just body weight but also lean tissue gain, a new University of Illinois study finds enhanced milk replacer with high crude-protein dry starter feed is the winning combination.

Hernias are one of the most common soft tissue injuries. Hernias form when intra-abdominal content, such as a loop of the intestine, squeezes through weak, defective or injured areas of the abdominal wall.
