Association between surgeon stress and major surgical complications

JAMA Surgery

2025-01-15
(Press-News.org)

About The Study: In this cohort study including 38 attending surgeons and 793 patients, increased surgeon stress at the beginning of a procedure was associated with improved clinical patient outcomes. The results are illustrative of the complex relationship between physiological stress and performance, identify a novel association between measurable surgeon human factors and patient outcomes, and may highlight opportunities to improve patient care.

How cryogenic microscopy could help strengthen food security

How cryogenic microscopy could help strengthen food security
2025-01-15
According to the United Nations, soil salinization affects between 20% and 40% of arable land globally, with human activity and climate change – especially rising sea levels – largely responsible for this process. While the human body needs sodium to function, this is not the case for most plants. In fact, excess salt around plants’ roots gradually blocks their access to water, stunting their growth, poisoning them and hastening their death. Ten million hectares of farmland are destroyed by soil salinization every year, posing a threat to global food security. Scientists at EPFL, ...

DNA damage can last unrepaired for years, changing our view of mutations

2025-01-15
While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that the damage has multiple chances to generate harmful mutations, which can lead to cancer. Scientists from the Wellcome Sanger Institute and their collaborators analysed family trees of hundreds of single cells from several individuals. The team pieced together these family trees from patterns of shared mutations between the cells, indicating common ancestors. Researchers uncovered unexpected ...

Could this fundamental discovery revolutionise fertiliser use in farming?

Could this fundamental discovery revolutionise fertiliser use in farming?
2025-01-15
Researchers have discovered a biological mechanism that makes plant roots more welcoming to beneficial soil microbes.  This discovery by John Innes Centre researchers paves the way for more environmentally friendly farming practices, potentially allowing farmers to use less fertiliser.   Production of most major crops relies on nitrate and phosphate fertilisers, but excessive fertiliser use harms the environment.  If we could use mutually beneficial relationships between plant roots and soil microbes to enhance nutrient uptake, ...

How one brain circuit encodes memories of both places and events

2025-01-15
CAMBRIDGE, MA -- Nearly 50 years ago, neuroscientists discovered cells within the brain’s hippocampus that store memories of specific locations. These cells also play an important role in storing memories of events, known as episodic memories. While the mechanism of how place cells encode spatial memory has been well-characterized, it has remained a puzzle how they encode episodic memories. A new model developed by MIT researchers explains how those place cells can be recruited to form episodic memories, even when there’s no spatial component. According to this model, place cells, along with grid cells found in the entorhinal cortex, act as a scaffold ...

ASU-led collaboration receives $11.2 million to build a Southwest Regional Direct Air Capture Hub

ASU-led collaboration receives $11.2 million to build a Southwest Regional Direct Air Capture Hub
2025-01-15
Arizona State University and a team of its collaborators have received $11.2 million in funding from the U.S. Department of Energy to begin developing a regional Direct Air Capture (DAC) Hub for removing carbon dioxide (CO2) from the atmosphere. The team will prepare to build a multi-site Direct Air Capture Hub located in the Four Corners area of the Southwestern United States. Additionally, the project will receive $11.2 million in matching funds from the project partners.  In May of 2022, the Biden administration announced the Bipartisan Infrastructure Law’s $3.5 billion DOE program to establish large-scale Direct Air Capture Hubs for removing carbon ...

Study finds strategies to minimize acne recurrence after taking medication for severe acne

2025-01-15
Isotretinoin, commonly referred to as Accutane, is the only approved medical treatment capable of inducing long-term remission of severe acne. Although highly effective, some individuals experience recurrence of acne after a course of treatment. A new study from researchers at Mass General Brigham examined how often acne recurs after isotretinoin and what factors might put patients at risk of acne coming back. They found that acne recurrence necessitating treatment with an oral medication such as oral antibiotics, spironolactone, or another ...

Deep learning designs proteins against deadly snake venom

Deep learning designs proteins against deadly snake venom
2025-01-15
New proteins not found in nature have now been designed to counteract certain highly poisonous components of snake venom. The deep learning, computational methods for developing these toxin-neutralizing proteins offer hope for creating safer, more cost-effective and more readily available therapeutics than those currently in use.   Each year more than 2 million people suffer snakebites. More than 100,000 of them die, according to the World Health Organization, and 300,000 suffer severe complications and lasting disability ...

A new geometric machine learning method promises to accelerate precision drug development

A new geometric machine learning method promises to accelerate precision drug development
2025-01-15
Proteins are the foundation of all life we currently know. With their virtually limitless diversity, they can perform a broad variety of biological functions, from delivering oxygen to cells and acting as chemical messengers to defending the body against pathogens. Furthermore, most biochemical reactions are only possible thanks to enzymes, a special type of protein catalysts. The molecular surface of proteins is the key to their function, such as docking small molecules or other proteins or driving ...

Ancient genomes reveal an Iron Age society centred on women

Ancient genomes reveal an Iron Age society centred on women
2025-01-15
An international team of geneticists, led by those from Trinity College Dublin, has joined forces with archaeologists from Bournemouth University to decipher the structure of British Iron Age society, finding evidence of female political and social empowerment.   The researchers seized upon a rare opportunity to sequence DNA from many members of a single community. They retrieved over 50 ancient genomes from a set of burial grounds in Dorset, southern England, in use before and after the Roman Conquest of AD 43. The results revealed that this community was centred around bonds of female-line descent.  Dr Lara Cassidy, Assistant Professor in Trinity’s Department of Genetics, led ...

How crickets co-exist with hostile ant hosts

How crickets co-exist with hostile ant hosts
2025-01-15
Researchers at Nagoya University in Japan have discovered sophisticated behavioral strategies that enable parasitic crickets to survive within ant colonies. Led by Ryoya Tanaka, the team documented how these insects successfully navigate life among potentially lethal hosts through precise evasion tactics. Their findings, published in Communications Biology, reveal remarkable adaptations that allow these cricket species to thrive in a hostile environment.  Animals that live in ant colonies, known as “ant guests”, exploit their hosts’ resources.  However, this ...
