Researchers have created a radical new view of how immune cells recognise threats such as viruses. The discovery could be used to design better vaccines and to gain a deeper insight into autoimmune diseases and allergies.

Researchers have developed a super-resolution microscopy method for the rapid differentiation of molecular structures in 3D.

Most cells in the bodies of living things duplicate their contents and physically separate into new cells through the process of cell division. But across many species, germ cells, those that become eggs or sperm, don't fully separate. They remain interconnected through small bridges called ring canals and cluster together. In a new study, researchers uncover how it is that germ cells in fruit flies form these ring canals, a finding that they say will provide new insights into a widely shared feature of development and into diseases in which cell division is disrupted.

Germination is a crucial stage in the life of a plant as it will leave the stage of seed resistant to various environmental constraints (climatic conditions, absence of nutritive elements, etc.) to become a seedling much more vulnerable. The survival of the young plant depends on the timing of this transition. It is therefore essential that this stage be finely controlled. Botanists have now discovered the internal thermometer of seeds that can delay or even block germination if temperatures are too high for the future seedling. This work could help optimize plant growth in a context of global warming.

Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with unique capabilities, according to a new study.

Obese fruit flies are the experimental subjects in a study of the causes of muscle function decline due to obesity. In humans, skeletal muscle plays a crucial role in metabolism, and muscle dysfunction due to human obesity can lead to insulin resistance and reduced energy levels.

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.

Researchers have discovered a strong immunological effect of the molecule LecB -- and a way to prevent it.

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.

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.

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.

When scientists disabled a single regulatory gene in a species of sea anemone, a stinging cell that shoots a venomous miniature harpoon for hunting and self-defense shifted to shoot a sticky thread that entangles prey instead, according to a new study.

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.
