Researchers have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than ticks, and how it gained and lost genes in the process.

Scientists have analyzed ancient DNA and compared more than 400 fossils from 17 natural history museums to figure out how and why extinct sloths got so big.

Every year, total allowable catches (TACs) and fishing quotas are set across Europe through a multi-step process -- and yet many fish stocks in EU waters remain overfished. A new analysis reveals that politically agreed-upon catch limits are not ...

Engineers developed a membrane that filters the components of crude oil by their molecular size, an advance that could dramatically reduce the amount of energy needed for crude oil fractionation.

New research shows how rapidly proliferating turf algae are waging 'chemical warfare' to inhibit the recovery of kelp forests along Maine's warming coast.

New studies reveal that both the public and healthcare providers often overlook social connection as a key factor in physical health, even though loneliness rivals smoking and obesity in health risks.

A new study proves that a type of genetic element called 'introners' are the mechanism by which many introns spread within and between species, also providing evidence of eight instances in which introners have transferred between unrelated species . ...

Earth's largest gold reserves are not kept inside Fort Knox, the United States Bullion Depository. In fact, they are hidden much deeper in the ground than one would expect. More than 99.999% of Earth's stores of gold and other precious metals lie ...

New research examining 11,700 years of bowhead whale persistence throughout the Arctic projects that sea ice loss due to climate change will cause their habitat to severely contract by up to 75 per cent.

Chemists have developed an efficient skeletal editing method for frequently used heteroaromatic structures. The technique could serve as a means to chemically modify biologically active compounds.
