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.....»»
New discoveries about how mosquitoes mate may help the fight against malaria
A high-pitched buzzing sound in your ear is an unmistakable sign that a female mosquito is out on the hunt—for they, not males, drink blood. Hearing that tone might make you turn to try to swat the pest. But for a male mosquito, that tone means it'.....»»
Researchers identify genes for low glycemic index and high protein in rice
A team of researchers at the International Rice Research Institute (IRRI) has identified genes and markers responsible for low glycemic index (GI) and high protein content in rice, using genetics and artificial intelligence classification methods......»»
Researchers explore design of polar crystalline solids of pure molecular materials
Harmeet Bhoday, a Missouri S&T Ph.D. student in chemistry from Chandigarh, India, was the lead author of an article titled "Perfect Polar Alignment of Parallel Beloamphiphile Layers: Improved Structural Design Bias Realized in Ferroelectric Crystals.....»»
Where are all the male teachers?
Step into any early childhood education center, and you'll encounter a whirlwind of activity: colorful art, energetic play and caring educators shaping young minds. But amid the vibrancy, there's something often missing … male educators......»»
Scientists unlock the secrets of how a key protein converts DNA into RNA
Researchers at the Department of Energy's SLAC National Accelerator Laboratory have uncovered new insights into the fundamental mechanisms of RNA polymerase II (Pol II), the protein responsible for transcribing DNA into RNA. Their study shows how the.....»»
Shedding light on the mechanism of yeast DNA repair
DNA damage is a cellular phenomenon that introduces structural abnormalities in double-stranded DNA. External factors, such as radiation or chemical agents, as well as internal factors, such as blocked DNA replication, can generate double-strand brea.....»»
Protein mutant stability can be inferred from AI-predicted structures
Researchers at the Center for Algorithmic and Robotized Synthesis within the Institute for Basic Science have taken a significant step forward in understanding the stability of proteins by leveraging the power of AI......»»
Arctic heat waves linked to sea ice loss, new study reveals
Amid global warming, heat waves are striking even the Arctic, a region once considered immune to such extreme weather events. Recent research reveals that these heat waves, particularly in the Barents-Kara Sea (BKS) during the boreal autumn, are not.....»»
Study shows an electrically-activated protein regulates spermatogenesis
Frankenstein's monster was brought to life by the judicious application of a little electricity; and a surprising number of processes in our bodies are regulated by electrical currents too. Now, researchers from Japan reveal that electricity may play.....»»
Using metal ion-linked nanostructures to improve immune response and boost breast tumor treatment
Immune checkpoint blockade (ICB) is one of the primary methods of tumor immunotherapy. However, clinical data have shown that only a portion of patients respond to ICB treatment. Since the tumor's immune-suppressive environment plays a crucial role i.....»»
Massive nationwide meat-linked outbreak kills 5 more, now largest since 2011

Chloroplast manipulation: A new strategy in pathogen warfare uncovered
A recent study has unveiled the sophisticated methods pathogens use to weaken plant defenses. It shows how a pathogen's effector protein targets the chloroplast protein StFC-II, increasing its levels in chloroplasts and reducing the plant's ability t.....»»
Uncertainty is a key factor in the relationship between work injury and mental health, research shows
Mental health and workplace injuries are known to be closely linked, but there are significant gaps in our deeper understanding of that bidirectional relationship. How does one affect the other, what moderates the relationship and what are the long-t.....»»
Simulation model shows ribosome tunnel"s impact on protein structures
Researchers at University of Tsukuba have developed a new model that simulates the internal environment of a ribosome—the cellular site of protein synthesis. Using computer simulations, they have analyzed the structures of various proteins within t.....»»
Love is blind for male fruit flies, who will choose sex over safety
Male fruit flies will become oblivious to physical danger as they become more engaged in courtship and sex, new research shows......»»
Authors propose multi-method framework for climate event attribution
At the two most recent meetings of the United Nations Framework Convention on Climate Change, delegates agreed to establish a fund to help developing nations suffering loss and damage due to events linked to climate change, such as floods, heat waves.....»»
Dual protein analysis approach provides potential way to slow cancer growth
Fighting cancer effectively often involves stopping cancer cells from multiplying, which requires understanding proteins that the cells rely on to survive. Protein profiling plays a critical role in this process by helping researchers identify protei.....»»
Dissecting caspase-2-mediated cell death: From intrinsic PIDDosome activation to chemical modulation
Caspase-2, an initiator caspase, plays a critical role in programmed cell death in response to certain cellular stresses. Its activation is facilitated by the PIDDosome, a multi-protein complex that assembles under conditions of genotoxic stress. Des.....»»
Record-breaking drought in southern China linked to Eurasian warming and tropical sea surface temperature
