Making heads or tails out of phospholipid synthesis

Most scientists agree that life on Earth began about 4 billion years ago, but they don't agree where—on land or in water. They know that about 2 billion years ago, single-celled organisms evolved into complex plants and ...

Energy harvesting goes organic, gets more flexible

Nanogenerators capable of converting mechanical energy into electricity are typically made from metal oxides and lead-based perovskites. But these inorganic materials aren't biocompatible, so the race is on to create natural ...

Towards a new generation of vegetation models

Plants and vegetation play a critical role in supporting life on Earth, but there is still a lot of uncertainty in our understanding of how exactly they affect the global carbon cycle and ecosystem services. A new IIASA-led ...

Simple self-charging battery offers power solutions for devices

A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term storage and improved ...

Organic porous structures on 2-D defect networks

NUS scientists have developed a method for self-assembly of hexagonal organic porous structures on molybdenum diselenide (MoSe2) film to create ordered nanostructures.

Researchers develop new variant of Maxwell's demon at nanoscale

Maxwell's demon is a machine proposed by James Clerk Maxwell in 1867. The hypothetical machine would use thermal fluctuations to obtain energy, apparently violating the second principle of thermodynamics. Now, researchers ...

A peptide against cannibalism

A worm whose favorite dish is – of all things—worm larvae has to take great care not to accidentally devour its own progeny. How these tiny worms of merely a millimeter in length manage to distinguish their own offspring ...

Rise of drones necessitates revision of laws of war

Today, it is almost impossible to imagine warfare without unmanned aerial vehicles, or drones. For instance, they have been deployed in the war in Iraq and Afghanistan. Are the current laws of war adequate to address the ...
