Employing a library of more than 1,000 chemicals, scientists investigated how agrochemicals affect insect populations. The scientists found that exposure to non-fatal amounts of 57 percent of the chemicals altered behavior in fruit fly larvae, while higher levels compromised long-term survival after acute exposure. These observations were worsened when the ambient temperature increased by four

New research has revealed Marri trees are critical to the survival of more than 80 species of native bee in Western Australia's South West region, which is one of the world's most biologically rich but threatened biodiversity hotspots. New Curtin-led research has revealed Marri trees are critical to the survival of more than 80 species

As the Arctic warms, polar bears now face a greater risk of contracting several pathogens than bears three decades ago, according to a new study.

Fossils from more than 600,000 years ago reveal how Southern Europe's animal community shifted between warm and cold climate fluctuations, according to a new study.

Maternal antibodies passed across the placenta can interfere with the response to the malaria vaccine, which would explain its lower efficacy in infants under five months of age, according to new research. The findings suggest that children younger than currently recommended by the WHO may benefit from the RTS,S and R21 malaria vaccines if they

Researchers have identified the first high-resolution experimentally determined structure in proteins that helps them survive harsh conditions such as radiation, heat and even the vacuum of space. A serendipitous encounter at a scientific meeting in 2019 has led to Michigan State University researchers identifying the first high-resolution experimentally determined structure in proteins that helps them

Researcher presents a new model for risk research which takes interactions into account and brings together various disciplines. LMU researcher presents a new model for risk research which takes interactions into account and brings together various disciplines. Climate disaster, pandemics, species extinction, violent conflict -- we live in a time of multiple crises. Researchers and

Bacteria and fungi from the wings of bats could play a significant role in saving them from white-nose syndrome (WNS), a fungal disease affecting the skin of wings and muzzle, which has nearly wiped out vulnerable bat populations across North America. Bacteria and fungi from the wings of bats could play a significant role in

Photosynthesis, the chemical reaction that enables almost all life on Earth, is extremely inefficient at capturing energy -- only around 1% of light energy that a plant absorbs is converted into chemical energy within the plant. Bioengineers propose a radical new method of food production that they call 'electro-agriculture.' The method essentially replaces photosynthesis with

A new report says any research into large-scale interventions in Earth's climate system must be grounded in sound ethical principles so society can make informed choices about whether to deploy them. As interest grows in geoengineering as a strategy for tackling global warming, the world's largest association of Earth and space scientists today launched an

The new mammal lived in Colorado 70 to 75 million years ago -- a time when a vast inland sea covered large portions of the state, and animals like sharks, turtles and giant crocodiles abounded. A team of paleontologists working near Rangely, Colorado, has uncovered a new (or, more accurately, very old) state resident --

Scientists have directly measured the behavioral responses of some of the most common marine mammals to military sonar. And the finding that surprised them most was that these animals were sensitive to the sounds at much lower levels than previously predicted. For the first time ever, a team including several UC Santa Cruz scientists have
