Molecular ‘catapult’ fires electrons at the limits of physics

Scientists at Cambridge University observed ultrafast charge transfer happening within a single molecular vibration, occurring on the natural timescale of atomic motion. The discovery challenges long-held theories about how solar energy systems work and reveals a new pathway to designing more efficient light-harvesting technologies.

Discovery of world’s oldest DNA breaks record by one million years

Scientists have identified two-million-year-old DNA fragments in northern Greenland's Ice Age sediment, providing insights into the past ecosystem and its potential to predict climate change. The discovery has sparked hopes that it could help academics build a picture of the DNA evolution of species still in existence today.

Fast food diet before pregnancy can impact breast milk and baby’s health, say scientists

A new study found that a fast food diet before pregnancy can negatively impact breast milk quality and baby's health, increasing the risk of conditions like heart disease and diabetes. Even short-term consumption of high sugar and fat diets affects women's health and fertility.

Placentas adapt when mothers have poor diets or low oxygen during pregnancy

Cambridge researchers have discovered that placentas can adapt to function properly despite poor diets or low oxygen during pregnancy, impacting on pregnancy outcomes and lifelong health. This adaptation helps the placenta transport sufficient oxygen and nutrients to the fetus, mitigating complications such as fetal growth restriction.

Study identifies traces of indigenous 'Taíno' in present-day Caribbean populations

Researchers have identified genetic evidence of Taíno ancestry in contemporary Puerto Ricans and other Caribbean communities, providing unprecedented insights into the genetic makeup of the region. The study's findings support claims by indigenous descendant communities that their ancestors survived European colonization.

Tiny changes in Parkinson's protein can have 'dramatic' impact on processes behind onset

Researchers have found that specific mutations in Parkinson's disease protein alpha-synuclein can dramatically affect microscopic processes leading to the condition's onset. The study suggests these tiny changes influence fibril formation and secondary nucleation, potentially contributing to the disease's development.
