Possible cause of male infertility linked to structural protein
Mature spermatozoa are characterized by a head, midpiece and a long tail for locomotion. Now, researchers from the University Hospital Bonn (UKB) and the Transdisciplinary Research Unit "Life & Health" at the University of Bonn have found that a loss.....»»
From chaos to order: Proteins can re-structure themselves to create important substances
The protein "MIPS" changes its internal structure when it becomes active. Its disordered active center becomes a defined structure with special functions. The protein plays a key role in the production of inositol, which is also known as vitamin B8,.....»»
New biosensor illuminates physiological signals in living animals
Eric Schreiter and Luke Lavis thought they had figured it out. In 2021, the Janelia group leaders reported that they had developed a way to combine Schreiter's engineered protein biosensors and Lavis's bright, fluorescent Janelia Fluor dyes......»»
New method developed to relocate misplaced proteins in cells
Cells are highly controlled spaces that rely on every protein being in the right place. Many diseases, including cancers and neurodegenerative disorders, are associated with misplaced proteins. In some cancers, for instance, a protein that normally s.....»»
Even the heaviest particles experience the usual quantum weirdness, new experiment shows
One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny chunks of light (photons), and low energies......»»

Study shows organonitrates in atmospheric particles vary with altitude
While atmospheric particles directly affect climate (e.g., cloud formation), sampling atmospheric particles aloft is practically challenging. Therefore, a full understanding of how particle composition is linked to environmental function remains limi.....»»
Double-edged STING: A new pathway involved in aging
A protein called STING, previously shown to control a pathway that contributes to antiviral signaling, also plays an important role in cellular stress clearance and cell survival, according to a new paper published in Molecular Cell......»»
Plant pathogen battle: A tomato protein"s dual role in defense and susceptibility
Tomatoes, a staple crop worldwide, are increasingly threatened by biotic stressors such as viruses, fungi, and bacteria, with the effects worsening under climate change. These challenges lead to reduced yields and compromised nutritional quality, hig.....»»
Beetles cooperate on tricky dung moves
Dung beetles are among the strongest animals in the world. They also possess an exceptional ability to cooperate. Research shows that female and male spider dung beetles together are able to move large dung balls across difficult obstacles. However,.....»»
New testing system uses Janus particles to rapidly and accurately detect COVID-19
The importance of testing for diseases was thrust into the limelight during the COVID-19 pandemic. Many of us have undergone a PCR (Polymerase Chain Reaction) or ELISA (Enzyme-Linked Immunosorbent Assay) test within the past four years......»»

Primates bond for their own benefit: Study underlines the decisive role that females play
Female and male primates often form close bonds, but not purely out of affection. Close relationships usually evolve when there is a clear benefit for both parties, with protection and reproductive control playing key roles......»»
An unexpected protein connection in maize growth and defense could enhance crop resilience
Maize (corn) is one of the most important staple crops in the world and has been extensively studied. Yet, many aspects of the genetic mechanisms regulating its growth and development remain unexplored......»»
Team discovers naturally occurring DNA-protein hybrids
Thanks to a serendipitous discovery and a lot of painstaking work, scientists can now build biohybrid molecules that combine the homing powers of DNA with the broad functional repertoire of proteins—without having to synthesize them one by one, res.....»»
Scientists discover how TGF-Beta sends its message even while tethered to the cell membrane
For years, scientists have thought that TGF-Beta, a signaling protein that holds sway over an astonishing array of cellular processes from embryonic development to cancer, could only do its work once it escaped a lasso-like "straitjacket.".....»»
Researchers explore the effects of the Black Lives Matter protests on racial bias
The murder of George Floyd in 2020 revived the Black Lives Matter movement, a large scale social movement that aims to highlight and reduce structural racism and inequality in the United States. The movement—and its coverage—strongly affected how.....»»
Edible insects show promise as sustainable nutritional source
As the global population grows and traditional livestock production increasingly strains environmental resources, there is a rising interest in alternative protein sources. Edible insects, particularly grasshoppers, are abundant in regions like Camer.....»»
Cyber insurance set for explosive growth
Cyber insurance is poised for exponential growth over the coming decade, but it remains a capital-intensive peril that requires structural innovation, according to CyberCube. The mid-range projection suggests that the US standalone cyber insurance ma.....»»
Organization of DNA in chromosomes can be explained by weak interactions between nucleosomes, research suggests
An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes......»»
Future foods: How non-thermal tech could transform starch consumption
Starch is a vital component of the human diet, serving as a primary energy source. However, high-glycemic starches are linked to the increasing prevalence of chronic diseases like obesity and diabetes. Traditional starch modification methods, such as.....»»
