西安交通大学科研团队证实T-carbon的预言和实验合成（图）
西安交通大学 科研团队 T-carbon
2017/12/12
T-carbon（又名T-碳），是中国科学院大学苏刚教授研究团队于2011年通过理论计算预言的一种新型三维碳结构，经过不懈的努力探索，近期被西安交大牛春明课题组和新加坡南洋理工大学联合研究团队在实验上成功合成，证实了苏刚研究团队的理论预言，使T-carbon成为可与石墨和金刚石比肩的碳的另一种三维新结构，从而在碳家族中增加了新成员。T-carbon的预言和实验合成是碳科学研究的一项突破性重要科学进...

Association of TCN2 rs1801198 c.776G>C polymorphism with markers of one-carbon metabolism and related diseases: a systematic review and meta-analysis of genetic association studies
cobalamin c.776G>C genetic association studies
2018/11/20
Background: Vitamin B-12 (cobalamin) deficiency may produce severe neurologic and hematologic manifestations. Approximately 20–25% of circulating cobalamin binds to transcobalamin 2 (TCN2), which is r...
Rusting pyrite ‘fool’s gold’ in glaciers a sign of increased carbon（图）
rusting pyrite fool’s gold glaciers increased carbon
2017/9/1
Some say the world will end in fire, some in ice. One more reason to hold with those who favor fire: USC scientists have found that rock and soil breakdown in glaciers generates more acidity and relea...

Two undergrads improve plant carbon-cycle models
2017/9/1
In the summer of 2012, two undergraduate students tackled a problem that plant ecology experts had overlooked for 30 years. The students demonstrated that different plant species vary in how they take...

carbon budget most likely overestimated
2017/9/1
While most climate scientists, including the Intergovernmental Panel on Climate Change, implicitly define "pre-industrial" to be in the late 1800's, a true non-industrially influenced baseline is prob...

A new CU Boulder study comparing dissolved black carbon deposition on ice and snow in ecosystems around the world (including Antarctica, the Arctic and alpine regions of the Himalayas, Rockies, Andes ...
Robert Hazen's field -- mineralogy -- might seem like the most appropriate scientific specialty for studying what's happening below Earth's surface. But, he says, that job requires partnering with sci...
Tiny Shells Indicate Big Changes to Global Carbon Cycle
Tiny Shells Indicate Big Changes Global Carbon Cycle
2017/7/20
Experiments with tiny, shelled organisms in the ocean suggest big changes to the global carbon cycle are underway, according to a study from the University of California, Davis. For the stud...
Study illuminates fate of marine carbon in last steps toward sequestration
fate marine carbon last steps toward sequestration
2017/7/20
The ocean sequesters massive amounts of carbon in the form of “dissolved organic matter,” and new research explains how an ancient group of cells in the dark ocean wrings the last bit of energy from c...
