Light-matter interaction without interference  

Quantum dots might constitute the foundation of quantum communication. They are an efficient interface between matter and light, with photons emitted by the quantum dots transporting information across large distances. However, structures form by default during the manufacture of quantum dots that interfere with communication. Researchers have now successfully eliminated these interferences.

A single gene determines whether a fly has a good sense of sight or a good sense of smell  

Trade-offs in the sizes of visual and olfactory organs are a common feature of animal evolution, but the underlying genetic and developmental mechanisms have not been clear. A study reveals that a single DNA variant that affects the timing of sensory organ development in fruit flies could explain the size trade-off between eyes and antennae, potentially providing a quick route to behavioral changes and adaptation.

Here's how early humans evaded immunodeficiency viruses  

The cryoEM structure of a simian immunodeficiency virus protein bound to primate proteins shows how a mutation in early humans allowed our ancestors to escape infection while monkeys and apes did not. SIV's Nef protein forms a solid link between two primate proteins, tetherin and AP-2, forcing the destruction of tetherin, which normally prevents new SIV virions from budding off. A mutation in human tetherin disrupted binding, thwarting SIV budding -- until HIV evolved a work-around.

Babies Need Healthy Microbiomes. But Where Do Microbiomes Come From?  

(Credit: Odua Images/Shutterstock) A human's genes are laid down at conception. A fetus' heart, brain and other organs start to form five weeks later. At six months, an unborn child has most of its body parts. But there is one essential component missing: the helpful bacteria, often referred to as the microbiome, that will inhabit its gut, skin and other organs. Our first interactions with microbes set the stage for health throughout our lives. Babies' microbiomes have...

High-precision technique stores cellular 'memory' in DNA  

Researchers have created a technology called DOMINO to store complex 'memories' in the DNA of living cells, including human cells. This memory storage capacity can form the foundation of complex circuits that trigger a cellular event, such as producing a fluorescent protein, when a specific event or sequence of events occurs.

There are way more species of horseshoe bats than scientists thought  

Horseshoe bats are bizarre-looking animals with giant ears and elaborate flaps of skin on their noses that they use like satellite dishes. There are about a hundred different species of horseshoe bats -- and that number is only going to grow. By studying the DNA of horseshoe bat specimens in museum collections, scientists have discovered that there are probably a dozen new species of horseshoe bat that haven't been officially described yet.

Scratching the surface of how your brain senses an itch  

Light touch plays a critical role in everyday tasks, such as picking up a glass or playing a musical instrument, as well as for detecting the touch of, say, biting insects. Researchers have discovered how neurons in the spinal cord help transmit such itch signals to the brain. The findings could help contribute to a better understanding of itch and could lead to new drugs to treat chronic itch, which occurs in such conditions as eczema, diabetes and even some cancers.

Slow electrons to combat cancer  

Slow electons can be used to destroy cancer cells - but how exactly this happens has not been well understood. Now scientists have been able to demonstrate that a previously little-observed effect actually plays a pivotal role: Due to a process called interatomic Coulombic decay, an ion can pass on additional energy to surrounding atoms. This frees a huge number of electrons, with precisely the right amount of energy to cause optimal damage to the DNA of the cancer cells.
