Recent paleogenomic research revealed that interbreeding was common among early human species. However, little was known about when, where, and how often this hominin interbreeding took place. Using paleoanthropological evidence, genetic data, and supercomputer simulations of past climate, a team of international researchers has found that interglacial climates and corresponding shifts in vegetation created common habitats for Neanderthals and Denisovans, increasing their chances for interbreeding and gene flow in parts of Europe and central Asia.

A new study shows that the cheek teeth of proboscideans (elephants and their ancient relatives) evolved in response to dietary changes due to vegetation changes and climate change in East Africa during the last 26 million years.

A new study finds that past changes in atmospheric CO2 and corresponding shifts in climate and vegetation played a key role in determining when and where early human species interbred.

A new study finds that around 1.12 million years ago a massive cooling event in the North Atlantic and corresponding shifts in climate, vegetation and food resources disrupted early human occupation of Europe.

Researchers have discovered that nuclear spin influences biological processes, challenging long-held beliefs. They found that certain isotopes behave differently in chiral environments, affecting oxygen dynamics and transport. This breakthrough could advance biotechnology, quantum biology, and NMR technology, with potential applications in isotope separation and medical imaging.

Heat load mitigation is critical to extending the lifetime of future fusion device. Researchers have found a way to explain the rotational temperatures measured in three different experimental fusion devices in Japan and the United States. Their model evaluates the surface interactions and electron-proton collisions of hydrogen molecules.

The Neolithic burial site of Gurgy 'les Noisats' in France revealed two unprecedentedly large family trees which allowed a Franco-German team to explore the social organization of the 6,700-year-old community. Based on multiple lines of evidence, the team describes a close kin group which practiced monogamy and female exogamy, and experienced generally stable times.

A team researchers has discovered molecular crystals capable of capturing iodine -- one of the most common radioactive fission products -- and other pollutants. The versatile crystals could be used for nuclear waste management and other energy-related applications and move the world closer to a net-zero future.

New research into public attitudes towards alternative shipping fuels shows public backing for biofuel and hydrogen. The study also found that nuclear was preferred to the heavy fuel oil (HFO) currently used in the global shipping industry, although both were perceived negatively. Ammonia had the least public support.

New measurements of how particles flow from collisions of different types of particles at the Relativistic Heavy Ion Collider (RHIC) have provided new insights into the origin of the shape of hot specks of matter generated in these collisions. The results may lead to a deeper understanding of the properties and dynamics of this form of matter, known as a quark-gluon plasma (QGP).

Fifteen years of archaeological work in the Tam Pa Ling cave in northeastern Laos has yielded a reliable chronology of early human occupation of the site. The team's excavations through the layers of sediments and bones that gradually washed into the cave and were left untouched for tens of thousands of years reveals that humans lived in the area for at least 70,000 years -- and likely even longer.
