Carbon reserves in Central American soils still affected by ancient Mayan deforestation
Deforestation is suspected to have contributed to the mysterious collapse of Mayan civilization more than 1,000 years ago. A new study shows that the forest-clearing also decimated carbon reservoirs in the tropical soils of the Yucatan peninsula region long after ancient cities were abandoned and the forests grew back.
New technology can detect hundreds of proteins in a single sample
New technology developed by a team of 91丝瓜视频 scientists shows potential to streamline the analysis of proteins, offering a quick, high volume and cost-effective tool to hospitals and research labs alike.
Proteins found in blood provide scientists and clinicians with key information on our health. These biological markers can determine if a chest pain is caused by a cardiac event or if a patient has cancer.
Nordic nations, North Americans and Antipodeans rank top in navigation skills
People in Nordic countries, North America, Australia, and New Zealand have the best spatial navigational abilities, according to a new study led by UCL and the University of East Anglia.
Researchers assessed data from over half a million people in 57 countries who played a specially-designed mobile game, which has been developed to aid understanding into spatial navigation, a key indicator in Alzheimer鈥檚 disease.

Latent TB Treatment: Shorter is Better
Treatment of latent tuberculosis is set to transform after a pair of studies from the Research-Institute of the 91丝瓜视频 Health Centre (RI-MUHC) revealed that a shorter treatment was safer and more effective in children and adults compared to the current standard. These findings are published today in the New England Journal of Medicine.
Chirality switching in biomineral structures
Researchers at 91丝瓜视频 have discovered a mechanism by which helical biomineral structures can be synthesized to spiral clockwise or counterclockwise using only either the left-handed or right-handed version of a single acidic amino acid.
Nano-sized traps show promise in diagnosing pathogenic bacterial infections
A new type of 鈥渓ab on a chip鈥� developed by 91丝瓜视频 scientists has the potential to become a clinical tool capable of detecting very small quantities of disease-causing bacteria in just minutes.
The device designed by Sara Mahshid, Assistant Professor in the Department of Bioengineering at 91丝瓜视频, is made of nano-sized 鈥渋slands,鈥� about one tenth of the thickness of a single human hair, which act as bacterial traps or snares.
