Newly discovered African 'climate seesaw' drove human evolution

A scientific consortium has found that ancient El Niño-like weather patterns were the primary drivers of environmental change in sub-Saharan Africa over the last 620 thousand years - the critical time-frame for the evolution of our species. The group found that these ancient weather patterns had more profound impacts in sub-Saharan Africa than glacial-interglacial cycles more commonly linked to human evolution.

Scientists discover a new genetic form of ALS in children

In a study of 11 medical-mystery patients, an international team of researchers has discovered a new and unique form of amyotrophic lateral sclerosis (ALS). Unlike most cases of ALS, the disease began attacking these patients during childhood, worsened more slowly than usual, and was linked to a gene, called SPTLC1, that is part of the body's fat production system.

New optimization approach helps design lighter carbon fiber composite materials

Carbon fibers, due to their superior strength and lightness, are popular in aerospace engineering applications. While much effort goes into improving the strength of carbon fiber composites, such as fiber-reinforced plastic, only fiber orientation optimization is considered. Now researchers have adopted a new design method that optimizes both fiber thickness and orientation, achieving weight reduction in reinforced plastic and opening doors to lighter aircrafts and automobiles.

Researchers find that oxygenation of Earth's surface is key to the evolution of large, complex multicellular organisms. If cells can access oxygen, they get a big metabolic benefit. However, when oxygen is scarce, it can't diffuse very far into organisms, so there is an evolutionary incentive for multicellular organisms to be small to ensure most of their cells can still access oxygen.
