Exception to laws of thermodynamics

A team of researchers led by a physics graduate student recently made the surprising discovery of what they call a 'shape-recovering liquid,' which defies some long-held expectations derived from the laws of thermodynamics. The research details a mixture of oil, water and magnetized particles that, when shaken, always quickly separates into what looks like the classically curvaceous lines of a Grecian urn.

Genes may influence our enjoyment of music

Does our ability to enjoy music have a biological basis? A genetic twin study shows that music enjoyment is partly heritable. Scientists uncovered genetic factors that influence the degree of music enjoyment, which were partly distinct from genes influencing general enjoyment of rewarding experiences or musical ability.

How calcium may have unlocked the origins of life's molecular asymmetry

Scientists have uncovered a surprising role for calcium in shaping the building blocks of life. Their study reveals that calcium ions help determine the molecular 'handedness' (chirality) of tartaric acid polymers -- an essential feature of biological molecules like DNA and proteins. This discovery sheds light on how life's uniform molecular structures may have first emerged on early Earth. In a twist on traditional theories, the researchers suggest that simple polyesters, in addition to peptides or nucleic acids, could have adopted this crucial trait on early Earth, offering a fresh perspective on life's chemical origins.

First ancient genomes from the Green Sahara deciphered

An international team has sequenced the first ancient genomes from the so-called Green Sahara, a period when the largest desert in the world temporarily turned into a humid savanna-like environment. By analyzing the DNA of two 7,000-year-old naturally mummified individuals excavated in the Takarkori rock shelter in southwestern Libya, the team showed that they belonged to a long-isolated and now extinct North African human lineage.

Thinner Arctic sea ice may affect global ocean circulation

One of the ocean currents in the Arctic Ocean is at risk of disappearing this century because of climate change, according to a new study. As a result, the North Atlantic could be flooded with freshwater which would weaken the global ocean circulation.
