Lean and mean: Maximizing 5G communications with an energy-efficient relay network

Scientists at Tokyo Institute of Technology (Tokyo Tech) have developed a wirelessly powered relay network for 5G systems. The proposed battery-free communication addresses the challenges of flexible deployment of relay networks. This design is both economical and energy-efficient. Such advances in 5G communications will create tremendous opportunities for a wide range of sectors.

Discovery of new key protein in cell function paves way for new therapies

Over time, we accumulate genetic damage that accelerates the aging process, increasing the risk of carcinogenesis. DNA is continually challenged by genotoxic factors that affect its fragile structure, inhibiting cell functions. To meet this challenge, cells have evolved a number of overlapping DNA repair mechanisms that detect and repair DNA damage. Nucleotide excision repair (NER) is a major DNA repair mechanism that cells employ to remove a wide class of bulky, DNA-distorting lesions from the genome. The importance of NER defects in man is illustrated by rare syndromes that either show increased cancer predisposition or dramatic features of accelerated aging, including depletion of fat depots. However, with the exception of cancer and aging, the links between defects in NER and the rapid onset of developmental defects in humans are not well understood.

Greenhouse gas emissions from reservoirs higher than previously expected

A new study in Global Biogeochemical Cycles shows per-area greenhouse gas emissions from the world's water reservoirs are around 29% higher than suggested by previous studies, but that practical measures could be taken to help reduce that impact.

Seeds of economic health disparities found in subsistence society

No billionaires live among the Tsimane people of Bolivia, although some are a bit better off than others. These subsistence communities on the edge of the Amazon also have fewer chronic health problems linked to the kind of dramatic economic disparity found in industrialized Western societies.
