New technique reveals genes underlying human evolution

One of the best ways to study human evolution is by comparing us with nonhuman species that, evolutionarily speaking, are closely related to us. That closeness can help scientists narrow down precisely what makes us human, ...

Scientists create model of an early human embryo from skin cells

In a discovery that will revolutionize research into the causes of early miscarriage, infertility and the study of early human developmentā€”an international team of scientists led by Monash University in Melbourne, Australia ...

Icy ocean worlds seismometer passes further testing in Greenland

The NASA-funded Seismometer to Investigate Ice and Ocean Structure (SIIOS) performed well in seismic experiments conducted in snowy summer Greenland, according to a new study by the SIIOS team led by the University of Arizona ...

Death enables complexity in chemical evolution

Simple systems can reproduce faster than complex ones. So, how can the complexity of life have arisen from simple chemical beginnings? Starting with a simple system of self-replicating fibers, chemists at the University of ...

Cybersecurity pioneers win mathematics Abel Prize

The Abel Prize, which honours achievements in mathematics, was awarded Wednesday to Hungarian Laszlo Lovasz and Israeli Avi Wigderson for their contributions to computer security, the Norwegian Academy of Science said.

Solar cells: Losses made visible on the nanoscale

Solar cells made of crystalline silicon achieve peak efficiencies, especially in combination with selective contacts made of amorphous silicon (a-Si:H). However, their efficiency is limited by losses in these contact layers. ...
