Bird genes are multitaskers, say scientists

Scientists from the University of Sheffield have found that although male and female birds have an almost identical set of genes, they function differently in each sex through a mechanism called alternative splicing.

New method allows precise gene control by light

A novel optical switch makes it possible to precisely control the lifespan of genetic copies. These are used by the cell as building instructions for the production of proteins. The method was developed by researchers from ...

The molecules responsible for transcriptional bursting

New insights into what causes neighboring, genetically identical stem cells in mouse embryos to behave differently in terms of the proteins they produce could have implications for regenerative medicine and the early detection ...

A worm's view on immunity

All higher organisms have an immune system that constitutes a biological defense mechanism to protect the body from pathogens and foreign substances. It consists of a complex network of different organs, cell types and molecules ...

The male Y chromosome does more than we thought

New light is being shed on a little-known role of Y chromosome genes, specific to males, that could explain why men suffer differently than women from various diseases, including COVID-19.

Finding the Achilles' heel of a killer parasite

Two studies led by UT Southwestern researchers shed light on the biology and potential vulnerabilities of schistosomes—parasitic flatworms that cause the little-known tropical disease schistosomiasis. The findings, published ...

Mystery of giant proton pump solved

Mitochondria are the powerhouses of our cells, generating energy that supports life. A giant molecular proton pump, called complex I, is crucial: It sets in motion a chain of reactions, creating a proton gradient that powers ...

Histone degradation after DNA damage enhances repair

DNA damage can occur anywhere in the genome, but most DNA is wrapped around nucleosomes making it inaccessible to the repair machinery. Researchers from the Gasser group now show that DNA damage induces histone depletion, ...

Improving Asian buffalo breeds with genomics

Selective breeding of water buffalo (Bubalus bubalis) and cattle with the help of genomics could help increase livestock productivity, thereby improving food security, nutrition and incomes for millions of smallholder farmers ...

Studying gene function in animal models

Researchers from the group of Jeroen Bakkers have described a thorough way to study the function of genes in model animals such as the zebrafish. In their study, published in Nature on September 23rd, they give an example ...

A new strategy of cell entry for some types of parvoviruses

Researchers at the Institut national de la recherche scientifique (INRS), in collaboration with American scientists, have discovered a new parvovirus strategy for reaching the cell nucleus, where they reproduce. The results ...

Placing barthelonids in evolutionary context

New species of microbial life are continually being identified, but localizing them on a phylogenetic tree is a challenge. Now, researchers at the University of Tsukuba have pinpointed barthelonids, a genus of free-living ...

Unraveling the genome in 3-D space

Proper folding of extremely long chromosomal DNA molecules is crucial for the correct functioning of the cell. Scientists from the Gerlich lab at IMBA—Institute of Molecular Biotechnology of the Austrian Academy of Sciences—developed ...

Patented 'molecular heaters' to increase crop yield

Researchers at the University of Amsterdam have developed a novel class of molecules capable of raising the temperature of plants. Application of such molecular heaters allows crops to grow at lower environmental temperatures. ...
