Curious and cryptic: New leaf insects discovered      (via sciencedaily.com)     Original source 

An international research team has described seven previously unknown species of leaf insects, also known as walking leaves. The insects belong to the stick and leaf insect order, which are known for their unusual appearance: they look confusingly similar to parts of plants such as twigs, bark or -- in the case of leaf insects -- leaves. This sophisticated camouflage provides excellent protection from predators as well as presenting a challenge to researchers. Genetic analysis enabled the researchers to discover 'cryptic species', which cannot be distinguished by their external appearance alone. The findings are not only important for the systematic study of leaf insects, but also for the protection of their diversity.

Quantum computer unveils atomic dynamics of light-sensitive molecules      (via sciencedaily.com) 

Researchers have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and offers an example of how advances in quantum computing are being used to investigate fundamental science.

Breakthrough in beta-lactam synthesis using nickel catalysts      (via sciencedaily.com) 

Researchers have made a significant breakthrough in the field of asymmetric synthesis of beta-lactams, which are prominent in bioactive compounds. Their innovative approach employs nickel and hydrocarbon sources that are abundant on Earth to access value-added beta-lactam products. The employment of nickel-hydride catalysis and alkenyl dioxazolone derivatives gives rise to the selective formation of four-membered lactam products.

Scientists solve mystery of why thousands of octopus migrate to deep-sea thermal springs      (via sciencedaily.com)     Original source 

Researchers used advanced technology to study a massive aggregation of deep-sea octopus gathered at thermal springs near an extinct underwater volcano off the coast of Central California. Warm water from hydrothermal springs accelerates development of octopus embryos, giving young octopus a better chance of survival. The Octopus Garden is the largest known aggregation of octopus on the planet -- the size of this nursery, and the abundance of other marine life that thrives in this rich community, highlight the need to understand and protect the hotspots of life on the deep seafloor from threats like climate change and seabed mining.

How a cup of water can unlock the secrets of our Universe      (via sciencedaily.com)     Original source 

A researcher made a discovery that could change our understanding of the universe. He reveals that there is a range in which fundamental constants can vary, allowing for the viscosity needed for life processes to occur within and between living cells. This is an important piece of the puzzle in determining where these constants come from and how they impact life as we know it.
