The COVID-19 pandemic resulted in millions of deaths. Despite an unparalleled collaborative research effort that led to effective vaccines and therapies being produced in record-breaking time, a complete understanding of the structure and lifecycle of the coronavirus known as SARS-CoV-2 is still lacking.

Who were the earliest ancestors of scorpions, spiders and horseshoe crabs? A Ph.D. student from the University of Lausanne (Switzerland), with the support of a CNRS researcher, has identified a fossil that fills the gap between modern species and those from the Cambrian period (505 million years ago), solving a long paleontological mystery.

Scientific discovery doesn't always require a high-tech laboratory or a hefty budget. Many people have a first-rate lab right in their own homes—their kitchen.

The city of Alameda has indefinitely shut down the Marine Cloud Brightening Program—a study based out of the University of Washington and set up on the deck of the U.S.S. Hornet to utilize the San Francisco Bay's ideal cloudy conditions—citing concerns over health and safety.

The intricate dance of atoms fusing and releasing energy has fascinated scientists for decades. Now, human ingenuity and artificial intelligence are coming together at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) to solve one of humankind's most pressing issues: generating clean, reliable energy from fusing plasma.

Colorado Parks and Wildlife officials removed 14 massive, invasive carp from a pond at an Arvada park last week, more than 30 years after the fish were introduced as part of a national study.

Meandering through the evergreens, spring's arrival was marked by unfurling fern and flowering berry plants.

As people age, they become more prone to blood clotting diseases, when blood cells called platelets clump together when they don't need to and can cause major issues such as strokes and cardiovascular disease. For decades, scientists have studied why older people's blood cells behave in this way, using their insights to develop the myriad of blood-thinning drugs now on the market for treating the leading cause of death in the United States.

Researchers have found that 2023 was the hottest summer in the Northern Hemisphere in the past 2,000 years, almost 4°C warmer than the coldest summer during the same period.

Philadelphia-area health systems are phasing out a common anesthesia gas that hangs in the atmosphere for 14 years. Desflurane is the most potent greenhouse gas found in hospitals, which are increasingly engaged in efforts to reduce their carbon footprint.

Waste from computers and cell phones, solar panels and other discarded electronics are becoming an important source of noble metals alongside mining. Researchers at the University of Helsinki have developed sustainable dissolution methods for noble metals.

A team of archaeologists at the University of York have returned to Skipsea in East Yorkshire to excavate the remains of a medieval timber hall uncovered near the site of a Norman castle.

Though more than 8 million babies have been born through in vitro fertilization (IVF), 70% of IVF implantations fail. As IVF is becoming a more common route to pregnancy in cases of infertility, there is a need for better understanding of embryonic development at this early stage.

Twinned nanoparticles have regions of clear symmetry that share the same crystal lattice, separated by a clear boundary. Changing the twin structure can affect the properties of the nanoparticles, which makes controlling twinning to create tailored nanomaterials an active area of research.

Resistance to antibiotics has been found in the environment across Scotland, according to a new international study involving Strathclyde.

A team of physicists from the University of Alabama in Huntsville and the Advanced Propulsion Laboratory at Applied Physics, in New York, has developed a model that shows it might be possible to create a subluminal warp drive.

In a study published in PeerJ, scientists have revealed the intricate vocal patterns of Bornean orangutans, shedding new light on the complexities of their communication. Titled "Vocal Complexity in the Long Calls of Bornean Orangutans," the research, led by Dr. Wendy Erb from the K. Lisa Yang Center for Conservation Bioacoustics at the Cornell Lab of Ornithology, unveils the remarkable diversity and variability within orangutan long call vocalizations.

Star and planet formation is a messy affair. It starts with the gravitational collapse of a gigantic cloud of gas and dust, which simultaneously produces massive stars, whose intense radiation field creates a harsh environment, as well as more modest stars, like our sun, surrounded by a planet-forming disk that is rich in organic materials.

A research team from the Department of Functional Composites in Composites Research Division at Korea Institute of Materials Science (KIMS) has successfully developed electromagnetic wave absorbers based on metal-organic frameworks (MOFs) that enhance dielectric and magnetic losses in the gigahertz (GHz) frequency band. The research was published in the journal Advanced Composites and Hybrid Materials on February 5, 2024.

Researchers at Pohang University of Science and Technology (POSTECH) have achieved a breakthrough in surpassing the limitations of traditional acoustic metalenses. They have successfully developed the first wide field-of-hearing metalens. Their research has been published in Nature Communications.

Diamond is the hardest material found in nature—diamond also has the highest thermal conductivity, allowing the most heat to flow through it rapidly.

The huge, long-lasting wildfires that have become increasingly common in recent years can cause changes in soil chemistry that affect water contamination, air quality, and plant growth. But these changes are poorly monitored and rarely factor into post-fire recovery efforts or risk assessments, according to a review study published May 14 in Nature Reviews Earth & Environment.

Researchers say the discovery of very high genetic diversity in leopards found in the Highveld region of South Africa has increased the need for conservation efforts to protect leopards in the country.

Capuchin monkeys are omnivores whose diet in the wild may include buds, flowers, leaves, seeds, nuts, fruit, and berries; as well as birds, eggs, small mammals, mollusks and arthropods such as insects and spiders.

The elements in the periodic table are divided into metals, semimetals and non-metals. The distinction is based on their chemical and physical properties and is determined, in particular, by the movement of electrons and the materials' ability to conduct electrical energy: metals are excellent conductors, semimetals have limited conductivity, non-metals are insulating materials, they do not conduct electricity.
