Plant diversity shapes chemical communication in ecosystems

Plant diversity shapes chemical communication in ecosystems

Researchers at the Max Planck Institute for Chemical Ecology and the University of Kiel have provided experimental evidence showing that reducing plant species diversity alters plant chemical signals across whole communities and within individual plants.

How actin wavefronts rescue T cell receptors from endocytosis

How actin wavefronts rescue T cell receptors from endocytosis

Every time our body encounters a new disease-causing agent, a crucial defense system called adaptive immunity comes into play. T cells, the top agents in this system, survey the internal environment of infected cells and start eliminating the pathogen. T cells are extremely dynamic, capable of changing their structure and makeup when making contact with other cells.

Tiny titans of recovery: Fossil burrows reveal resilient micro-ecosystem after global mass extinction

Tiny titans of recovery: Fossil burrows reveal resilient micro-ecosystem after global mass extinction

An international team of scientists from South Africa, Canada, France and the UK has uncovered fossil evidence of a tiny ecosystem that helped kick-start the recovery of Earth's oceans after a global mass extinction.

Sharks are famous for fearsome teeth, but ocean acidification could make them weaker

Sharks are famous for fearsome teeth, but ocean acidification could make them weaker

Sharks are the most feared predators in the sea, and their survival hinges on fearsome teeth that regrow throughout their lives. But changes in the ocean's chemistry could put those weapons at risk.

Honeycomb lattice sweetens quantum materials development

Honeycomb lattice sweetens quantum materials development

Researchers at the Department of Energy's Oak Ridge National Laboratory are pioneering the design and synthesis of quantum materials, which are central to discovery science involving synergies with quantum computation. These innovative materials, including magnetic compounds with honeycomb-patterned lattices, have the potential to host states of matter with exotic behavior.

Revealing the cell's nanocourier at work

Revealing the cell's nanocourier at work

An international group of researchers led by Pompeu Fabra University has discovered the nanomachine that controls constitutive exocytosis: the uninterrupted delivery of spherical molecular packages to the cell surface. This is an essential activity present in virtually all organisms to preserve cell fitness and other vital functions such as communication with the cell's exterior, cell growth and division.

Organic solvents enable chirality control in inorganic crystals

Organic solvents enable chirality control in inorganic crystals

Chirality—often described as "handedness"—is a fundamental property of nature, underlying the behavior of molecules ranging from DNA to pharmaceuticals. While chemists have long known how to separate left- and right-handed forms of organic compounds, achieving the same control in inorganic crystals has remained a major scientific challenge.

Cells use dual strategies to fine-tune inflammatory gene activation

Cells use dual strategies to fine-tune inflammatory gene activation

Inflammation has to fight pathogens fast—but it can't get out of control. Researchers at the German Cancer Research Center (DKFZ) have now deciphered in more detail how the organism masters this balancing act. Their work shows that cells use two different strategies to precisely control inflammatory genes and thus precisely regulate the inflammatory response.

New temperature record challenges extreme high-latitude warmth paradigm

New temperature record challenges extreme high-latitude warmth paradigm

Reliable predictions of how the Earth's climate will respond as atmospheric carbon dioxide levels increase are based on climate models. These models, in turn, are based on data from past geological times in which the CO2 content in the Earth's atmosphere changed in a similar way to today and the near future. The data originate from measurable indicators (proxies), the interpretation of which is used to reconstruct the climate of the past.

Nationwide racial bias shapes media reporting on gun violence, study suggests

Nationwide racial bias shapes media reporting on gun violence, study suggests

Mass shootings in white-majority neighborhoods received roughly twice the news coverage of mass shootings in neighborhoods where a majority of residents were people of color, while coverage of police-involved shootings was disproportionately high in majority-minority communities, according to new research.
