Recording the activity of large populations of single neurons in the brain over long periods of time is crucial to further our understanding of neural circuits, to enable novel medical device-based therapies and, in the future, for brain–computer i.....»»
Study tracks how wetland tree stem emissions vary by season, location, and hydrological conditions
The recent rise in atmospheric methane (CH4) has drawn increased attention to the potent greenhouse gas, which is approximately 45 times more powerful than carbon dioxide at trapping heat in the atmosphere. About 60% of global methane emissions are a.....»»
Researchers uncover molecular mechanisms behind effects of MXene nanoparticles on muscle regeneration
Tissue engineering, which involves the use of grafts or scaffolds to aid cell regeneration, is emerging as a key medical practice for treating volumetric muscle loss (VML), a condition where a significant amount of muscle tissue is lost beyond the bo.....»»

Wildlife smoke may curb movement, sociability of woodpeckers
Human-driven climate change has helped transform many forests into kindling: A 2016 study found that greenhouse-aided warming and drought had more than doubled the area of fire-susceptible forest in the western U.S. since the mid-1980s. And of the Ca.....»»
New method for incorporating structurally unusual amino acids into proteins
A team of biochemists at the Medical Research Council Laboratory of Molecular Biology at Cambridge has developed a new method to incorporate structurally unusual amino acids into proteins by using bacteria. The method is described in the journal Natu.....»»
Study finds global carbon markets overcredit cookstove greenhouse gas reductions by a factor of 10
The fastest growing type of offset on the global carbon market subsidizes the distribution of efficient cookstoves in developing countries to reduce greenhouse gas emissions, but a new study finds that the credits overestimate the stoves' carbon savi.....»»
Investigating the presence of environmental rare earth elements in activated sludge systems
The pandemic has triggered a major increase in the use of medical facilities and drugs, which has exacerbated pollution in wastewater biochemical treatment systems. Pollution from environmental rare earth elements (REE) has increased due to the wides.....»»
Researchers develop high-efficiency carbon dioxide electroreduction system for reducing carbon footprint
Global warming continues to pose a threat to human society and ecological systems, and carbon dioxide accounts for the largest proportion of the greenhouse gases that dominate climate warming......»»
Energy supply in human cells is subject to quality control, researchers discover
Researchers at the University Medical Center Göttingen (UMG) have discovered a new quality control mechanism that regulates energy production in human cells. This process takes place in mitochondria, the power plants of the cell......»»
Masimo CEO says Apple Watch users better off without blood oxygen feature, calls it unreliable
Apple on Thursday began selling revised models of the Apple Watch Series 9 and Ultra 2 in the US without the blood oxygen feature as the company faces a patent dispute with medical company Masimo. In the midst of this situation, Masimo CEO Joe Kiani.....»»
Helium is essential for research, medical equipment, but it"s nonrenewable and difficult to recycle
The next time you pick up balloons for your big party, remember the helium gas in those balloons is destined for the stars. Helium is so light that it easily escapes Earth's gravity, and all helium will eventually make its way into space. Like fossil.....»»
