Once upon a time, prevailing scientific opinion might have pronounced recently published research as unneeded. Now, climate change implications have heightened the need for this line of research. Flowers emit scent chemicals called volatile organic compounds (VOCs). Earlier this year, a study identified a protein that plays a key role in helping petunias emit volatiles.

An international team of bee researchers has integrated a calcium sensor into honey bees to enable the study of neural information processing including response to odors. This also provides insights into how social behavior is located in the brain.

A major new study reveals a 'traffic light' mechanism controlling genetic activity within cells -- a system which could potentially be targeted by cancer drugs already in development. The research describes how 'epigenetic' changes to the structure of DNA can act as a stop-go signal in determining whether a gene should be read. Unlike our genetic make-up, which is well understood, the world of epigenetics is still largely unexplored and referred to as the 'dark matter' of the genome.

Scientists thought a gold-throated hummingbird was a new species. DNA revealed that it's a hybrid of two different species, each with pink throats. The discovery sheds light on how birds produce feather colors and how hummingbirds evolved their dazzling hues.

Researchers describe how gut-on-a-chip devices can bridge lab models and human biology. Modeling the microbiome is particularly difficult because of its unique environmental conditions, but through creative design, gut-on-a-chip devices can simulate many of these properties, such as the gut's anaerobic atmosphere, fluid flow, and pulses of contraction/relaxation. Growing intestinal cells in this environment means that they more closely resemble human biology compared to standard laboratory cell cultures.

Biochemists have succeeded in resurrecting the ancestral genes of five detoxifying enzymes which are present in all tetrapods to show how their divergence in function has occurred.

By simulating early Earth conditions in the lab, researchers have found that without specific amino acids, ancient proteins would not have known how to evolve into everything alive on the planet today -- including plants, animals, and humans.

A new form of heterostructure of layered two-dimensional (2D) materials may enable quantum computing to overcome key barriers to its widespread application, according to an international team of researchers.

Textbooks will tell you that in dividing cells, production of new DNA peaks during the S-phase, while production of other macromolecules, such as proteins, lipids, and polysaccharides, continues at more or less the same level. Molecular biologists have now discovered that this is not true: protein synthesis shows two peaks and lipid synthesis peaks once.

Haematopoietic stem cell transplantation for the treatment of severe blood cancers is the only medical intervention that has cured two people living with HIV in the past. An international group of physicians and researchers has now identified another case in which HIV infection has been shown to be cured in the same way. The successful healing process of this third patient was for the first time characterized in great detail virologically and immunologically over a time span of ten years.

Influenza viruses are becoming increasingly resilient to medicines. For this reason, new active ingredients are needed. Important findings in this regard have been provided: for the virus to proliferate, the polymerase of the influenza A virus has to be modified many times through enzymes in the host cells. The team of researchers was able to produce a comprehensive map of types of modification. Medicines directed against the enzymes woud be resilient to rapid mutations in the virus, thus offering great potential for the future.

One of the striking aspects of the quantum world is that a particle, say, an electron, is also a wave, meaning that it exists in many places at the same time. Researchers make use of this property to develop a new type of tool -- the quantum twisting microscope (QTM) -- that can create novel quantum materials while simultaneously gazing into the most fundamental quantum nature of their electrons.

Given the growing importance of graphite in energy storage technologies, a team of esearchers has conducted a study exploring ways to reduce reliance on imports of the in high-demand mineral, which powers everything from electric vehicles (EVs) to cell phones.

Physicists have directly measured, for the first time at nanometer resolution, the fluid-like flow of electrons in graphene. The results have applications in developing new, low-resistance materials, where electrical transport would be more efficient.
