NASA's Perseverance rover has begun drilling into the surface of Mars and will collect rock samples to be picked up by future missions for analysis by scientists on Earth.

A new frog-legged beetle species, Pulchritudo attenboroughi, or Attenborough's Beauty, was announced today in the scientific journal Papers in Palaeontology. Frank Krell, Denver Museum of Nature & Science Senior Curator of Entomology, and Francesco Vitali, National Museum of Natural History of Luxembourg Invertebrate Zoology Collections Curator, worked together to identify this new species.

In the battle to save moose from winter ticks, fungi on small grains of millet could be the ultimate weapon. Morris Animal Foundation-funded researchers at the University of Vermont recently produced granular formulations of insect-killing fungi and successfully tested their efficacy against winter tick larvae under laboratory conditions. The team reported their findings in Biocontrol Science and...

Following the killing of George Floyd by a Minneapolis police officer in May of 2020, many have argued for defunding the police. But these appeals have not been guided by research into the scale or nature of issues that police handle. A new study analyzed millions of 911 calls for service across nine U.S. police agencies to determine how defunding the police might be handled.

High-angle annular dark-field scanning transmission electron microscopy can be used to determine complex conformational structures of both crystalline and amorphous polynuclear non-planar coordination molecules, as shown by scientists from Tokyo Institute of Technology (Tokyo Tech). Using iridium as a tracer metal, they were successful in determining the different conformations of a highly...

Australian researchers have revealed how the bacterium Streptococcus pneumoniae (pneumococcus) obtains the essential nutrient, manganese, from our bodies, which could lead to better therapies to target what is a life-threatening, antibiotic-resistant pathogen.

Scientists are using two bird's-eye views—remote sensing from satellites and the voices of Twitter—to synthesize the environmental impacts of sprawling infrastructure projects and how the people who live amongst them feel about the changes.

The Paraná River, one of the main commercial waterways in South America, has reached its lowest level in nearly 80 years due to a prolonged drought in Brazil that scientists attribute to climate change.

As they watch the Olympic Games in Japan, a group of University of Toronto students is learning about the origins and historical significance of such athletic competitions, which began almost 3,000 years ago.

Among the deadliest of foodborne pathogens, Listeria monocytogenes soon may become easier to track down in food recalls and other investigations, thanks to a new genomic and geological mapping tool created by Cornell food scientists.

If you are a researcher who wants to see how just a few cells in an organism are behaving, it is no simple task. The human body contains approximately 37 trillion cells; the fruit fly flitting around the overripe bananas on your counter might have 50,000 cells. Even Caenorhabditis elegans, a tiny worm commonly used in biological research, can have as many as 3,000 cells. So, how do you monitor a...

University of Minnesota Twin Cities College of Science and Engineering researchers have invented a cheaper, safer, and simpler technology that will allow a "stubborn" group of metals and metal oxides to be made into thin films used in many electronics, computer components, and other applications.

A new database of lead isotopes found in the Iberian Peninsula has been created.

A single cell can reveal much about the biological world through genomic sequencing. Scientists can compare a single, isolated cell to other samples, analyzing the differences and similarities to better understand how the organisms originated and evolved—or even to discover entirely new species.

Radioactive materials including 137Cs (cesium-137, half-life: 30.1 years) were released into the environment following the accident at Fukushima Daiichi Nuclear Power Plant. It has been about 10 years since the accident, but 137Cs remains in the environment, especially in forests. Many researchers have been studying the dynamics and transport processes of radioactive materials in the environment....

Metal-halide perovskites are a new class of semiconductor materials for LED display and solar-energy harvesting. However, the best-performing devices are often made from lead (Pb)-based perovskites, whose toxicity may cause potential environmental concerns. To resolve the toxicity problem, an effective method has been the use of tin (Sn) as a partial or full replacement of lead in the perovskite...

In the early stages of the Universe, quarks and gluons were quickly confined to protons and neutrons which went on to form atoms. With particle accelerators reaching increasingly higher energy levels the opportunity to study this fleeting primordial state of matter has finally arrived.

Three dimensional (3D) nano-networks promise a new era in modern solid state physics with numerous applications in photonics, bio-medicine, and spintronics. The realization of 3D magnetic nano-architectures could enable ultra-fast and low-energy data storage devices. Due to competing magnetic interactions in these systems, magnetic charges or magnetic monopoles can emerge, which can be utilized as...

Extreme temperature events will likely increase and cause severe damage to human society and natural ecosystem under climate change and urbanization. Compared to daytime, nighttime heat waves reduce people's ability to cool off and prevent the human body from recovery after daytime heat exposure, and therefore increasing risks of heat related illness and mortality. 

Typhonium is the largest genus in the aroid family (Araceae). It comprises of about 100 species of tuberous perennial herbs, and is most often found in wooded areas. 12 species in the genus Typhonium have been found in Myanmar.

New technology that enables more efficient and effective transfer printing for electronic devices has been developed by researchers at the Daegu Gyeongbuk Institute of Science and Technology (DGIST) in Korea.

The Mediterranean will be hit by ever fiercer heatwaves, drought and fires supercharged by rising temperatures, according to a draft United Nations assessment seen exclusively by AFP that warns the region is a "climate change hotspot".

What is the best option for individual water consumption if we take into account both health and environmental impacts? The answer to that question, according to a new study led by the Barcelona Institute for Global Health (ISGlobal), a center supported by the "la Caixa" Foundation, is that, at least in the city of Barcelona, tap water is the option that offers more overall benefits.

New analysis of two recently translated papers, first published in the 1850s, assesses the early methods used by Alfred Clebsch to describe the flow of incompressible fluids, and explores their impact on active areas of cutting-edge research
