Unraveling the interactions of individual sugar molecules with cells
Sugars interact with the cell surface through sugar-binding proteins called lectins. These interactions play a fundamental role in many of the cell's biological processes. One important function is the modulation of the immune response towards an out.....»»
Beta cells: New insights into the structure, interactions and neuronal networking of primary cilia
Dysfunctions of the tiny cell processes (primary cilia) of the pancreatic beta cells could be a cause of type 2 diabetes. Little is known about the structure and function of these cilia. An international research team led by DZD researchers from the.....»»

"Wing spreading" adaptation in fruit flies offers insights into female courtship behavior
In the game of evolution, key behavioral adaptations that confer fitness in survival and reproduction, paying tremendous dividends for an individual's progeny, may seemingly arise from thin air—so much so, even familiar species like the humble frui.....»»
Chiral molecular self-assemblies that absorb light boost singlet fission process, research demonstrates
In organic molecules, an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge). They are held together by Coulombic attraction and can move within molecular assemblies. Singlet fission (SF) is a process wher.....»»
Researchers challenge longstanding theories in cellular reprogramming
A team led by researchers at the University of Toronto has discovered that a group of cells located in the skin and other areas of the body, called neural crest stem cells, are the source of reprogrammed neurons found by other researchers......»»
Courts in UK may permit companies to be convicted of crimes even when no individual employee is criminally liable
Due to loopholes that remain despite recent reforms to corporate criminal law in the UK, University of Surrey academics are calling for a new legal approach that could hold companies accountable for economic crimes, even when no single employee posse.....»»

Mathematical model decodes protein interactions to show how condensates form
Biological cells are incredibly complex mixes of proteins, nucleic acids, lipids and carbohydrates. A model developed by two RIKEN researchers helps explain why components of the same type sometimes do and sometimes don't spontaneously come together.....»»
International team discovers small molecules that regulate how fast plant leaves age
Two small molecules that are produced by the plant Arabidopsis thaliana are shown to have the opposite effect on how fast its leaves age. The molecules are peptides, short chains of amino acids. While the peptide SCOOP10 accelerates aging, SCOOP12 su.....»»
Single-molecule tracking technology streamlines drug discovery

Researchers observe stick-slip phenomenon in carbon nanotube fibers
The shapes of simple polyatomic molecules such as carbon dioxide and methane are characterized by a specific symmetry depending on the manner of linking of the atoms. Nano- to micrometer-sized particles that mimic the shapes of such polyatomic molecu.....»»
Algae-jellyfish relationship provides insight on immune health
Marine animals like jellyfish, corals and sea anemones often live with algae inside their cells in a symbiotic relationship. The animals give the algae nutrients and a place to live; in return, algae give the animals some of the food they make from s.....»»
Solar-powered animal cells: Combining chloroplasts from algae with hamster cells
Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining chloroplasts (chlorophyll containing structures in.....»»
Compact in-incubator imaging device allows real-time remote monitoring of cell growth
Unlike most cells in the human body, stem cells have the unique ability to divide indefinitely. This property makes them especially appealing to scientists exploring ways to extend human lifespans or develop new methods for repairing damaged tissues......»»
