Scientists reveal new information about the role humans have played in large-scale land loss in the Mississippi River Delta -- crucial information in determining solutions to the crisis.

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.

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.

Submarine landslides have a large tsunami potential and occurred on the central Norwegian shelf more frequently in the past than previously thought. Scientists investigate the Nyegga landslide off the coast of Norway. The submarine landslide occurred in the same area as the well-known Storegga event 8,150 years ago. The new findings suggest that approximately one-third of the seafloor material missing -- previously attributed to the Storegga event -- was removed by the Nyegga event 20,000 years ago. This raises questions about the frequency of large submarine landslides and their associated tsunami hazard.

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.

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.

Researchers have generated the first induced pluripotent stem cells (iPSCs) from bats, gaining valuable insights into the close relationship between bats and viruses.

Researchers made the stunning discovery that telomeres contain genetic information to produce two small proteins, one of which they found is elevated in some human cancer cells, as well as cells from patients suffering from telomere-related defects.

Using artificial intelligence (AI), researchers can now follow cell movement across time and space. The method could be very helpful for developing more effective cancer medications.

The behavioral disorders observed in autism are associated with a multitude of genetic alterations. Scientists have now found another molecular cause for this condition. The transcription factor MYT1L normally protects the molecular identity of nerve cells. If it is genetically switched off in human nerve cells or in mice, the functional changes and symptoms typical of autism occur. A drug that blocks sodium channels in the cell membrane can reverse the consequences of MYT1L failure and alleviate the functional and behavioral abnormalities in mice.

Scientists have created a new technology to assemble matter in 3D. Their concept uses multiple acoustic holograms to generate pressure fields with which solid particles, gel beads and even biological cells can be printed. These results pave the way for novel 3D cell culture techniques with applications in biomedical engineering.

Bee researchers have identified a new gene in honeybees, which is responsible for the dimorphic eye differentiation between males and females of the species. The researchers have now presented this gene and the evolutionary genetic conclusions they have drawn from it.
