Thus, using electrical signals as indicators and targets for cancer treatments could potentially improve the outcome for cancer patients. A team of researchers from

Climate Change Might Be Driving Albatrosses to Divorce
3minAlbatrosses do not fall in love the way humans do. When the birds couple up, it’s almost always for keeps.

8hAlkynes have many uses in industry. Until now, it was assumed that gold- or platinum-based catalysts were absolutely necessary for certain chemical reactions with alkynes. Chemists at Martin Luther University Halle-Wittenberg (MLU) have now succeeded in carrying out the same reactions with considerably less expensive materials. The team reports on its work in the Journal of the American Chemical S

Study proposes a two-step plan to combat China's waning agricultural exports
8hFor the past 17 years, China has imported more agricultural products than it has exported. Finding ways to improve the export competitiveness of its agricultural products has been a pressing challenge for China since it joined the World Trade Organization (WTO) in 2001. To date, research into the issue has largely focused on the macro perspective; little research has been conducted from a micro po
Pore-mouth catalysis boosting the formation of iso-paraffins from syngas over bifunctional catalysts
8hThe bifunctional catalysts consisting of spinel ZnAlOx and SAPO-11 zeolite can directly convert syngas (a mixture of H2 and CO) into high-quality gasoline. The selectivity of C5–C11 gasoline-range hydrocarbons can reach 79% with a high content of iso-paraffins. The formation of iso-paraffins over ZnAlOx/SAPO-11 catalyst follows a pore-mouth catalysis mechanism, which means the isomerization of lin
