A new study busts the long-held economic belief that humans are all motivated to want more and more, which could have important implications for sustainability policies.

Researchers have identified and reconstructed the first ancient genome of E. coli, using fragments extracted from the gallstone of a 16th century mummy.

Scientists have identified the biochemical signals that control the emergence of the body pattern in the primate embryo. This will guide work to understand birth defects and pregnancy loss in humans.

The cerebellum is essential for sensorimotor control but also contributes to higher cognitive functions including social behaviors. Researchers uncovered how dopamine in the cerebellum modulates social behaviors via its action on D2 receptors (D2R). Th…

During recent decades, the rate of infertility among women in the United States has remained largely the same, according to researchers. Their new analysis of data collected from 1995 and 2019 found that infertility is more common among women who are o…

A new study shows targeting a protein in smooth muscle cells can block and decrease buildup of atherosclerotic plaque in mouse models, according to researchers.

Researchers have developed a unique 3D printed system for harvesting stem cells from bioreactors.

A new study has unraveled the earliest evidence for domestication of a fruit tree, researchers report. The researchers analyzed remnants of charcoal from the Chalcolithic site of Tel Zaf in the Jordan Valley and determined that they came from olive tre…

Increasing frequency and size of wildfires in the United States over the past several decades affect everything from human life and health to air quality, biodiversity, and land use. The US dairy industry is not exempt from these effects. The Western s…

Researchers developed a toolkit for investigating the molecular mechanisms governing the parasitic nature of the wasp species Asobara japonica. They first used DNA and RNA-sequencing-based techniques to identify genes controlling the wasp’s body color,…

Several species of California bumble bees have gone missing in the first statewide census of the fuzzy pollinators in 40 years.

Researchers have reported that in the liverwort Marchantia polymorpha, the number of mitochondria in the spermatozoid (sperm) is controlled by autophagy during spermiogenesis.

Heatwaves are making more people in rural areas of England severely ill today than they were in the 1980s, according to new research.

To develop new drugs and vaccines, detailed knowledge about nature’s smallest biological building blocks — the biomolecules — is required. Researchers are now presenting a groundbreaking microscopy technique that allows proteins, DNA and other tiny b…

Researchers have found that more than a quarter of asthma patients are still over-using inhalers intended for rapid relief of symptoms. Overuse of these inhalers is linked to an increased risk of hospital admissions and severe asthma attacks. They also…

The violent death throes of a nearby star so thoroughly disrupted its planetary system that the dead star left behind — known as a white dwarf — is sucking in debris from both the system’s inner and outer reaches, astronomers report.

Astronomers using data from the VLA Sky Survey have discovered one of the youngest known neutron stars — possibly as young as only 14 years. The dense remnant of a supernova explosion was revealed when bright radio emission powered by the pulsar’s pow…

The reintroduction of the wild-type poliovirus or circulating vaccine-derived poliovirus (cVDPV) is a sizeable threat in Ukraine, which is considered a high-risk country for vaccine-preventable infections, including poliomyelitis, an extremely dangerou…

Plastic pollution in the ocean, which can support microbial communities, may serve as a source for novel antibiotics, according to a new student-led study conducted in collaboration with the Scripps Institution of Oceanography.

Space scientists have discovered a ‘super Jupiter’ orbiting a white dwarf, detected using direct observations with the European Space Agency (ESA)’s Gaia mission.
