Identifying and delineating cell structures in microscopy images is crucial for understanding the complex processes of life. This task is called “segmentation” and it enables a range of applications, such as analysing the reaction of cells to drug treatments, or comparing cell structures in different genotypes. It was already possible to carry out automatic segmentation of those biological structures but the dedicated methods only worked in specific conditions and adapting them to new conditions was costly. An international ...

AURORA, Colo. (Feb. 25, 2025) – A new study, published today in The Lancet Respiratory Medicine, tested whether a set of interventions to keep lungs expanded before, during, and after abdominal surgery could lower the risk of serious breathing problems in patients compared to the usual care at 17 academic hospitals in the U.S. The research has determined that these interventions for open abdominal surgery do not result in less severe breathing problems as compared to the usual care in those hospitals. Adult abdominal surgery patient enrollees were either given a lung expansion set of interventions or the typical care plan to follow at each hospital. ...

How can the loss of species and habitats in agricultural landscapes be stopped? Up to now, measures have mostly been implemented by individual farms. In contrast, agri-environmental measures that are planned across farms at landscape level offer greater potential for creating suitable habitats for different species as a mosaic in the landscape. However, successful landscape level approaches also require cooperation between farms and other stakeholders from local governments, politics and nature conservation. Researchers at the University of Göttingen have therefore identified ...

LA JOLLA, CA—Scientists at La Jolla Institute for Immunology (LJI) have found a potential new target for treating Parkinson's disease. Their new research reveals how a protein in brain cells may drive Parkinson's onset—and offers a possible explanation for why Parkinson's is much more common in men.  In recent years, LJI scientists have found increasing evidence that autoimmunity plays a role in the onset of Parkinson's disease. Their recent study in The Journal of Clinical Investigation shows that PINK1 appears to mark ...

WASHINGTON—The Society for Cardiovascular Angiography & Interventions (SCAI) has published an expert consensus statement that provides interventional cardiologists, cardiothoracic surgeons, and heart teams with practical guidance for selecting patients and performing alternative access transaortic valve replacement (TAVR). TAVR has seen substantial growth over the past decade, becoming a standard of care for many patients with asymptomatic aortic stenosis. However, some patients face challenges due to inadequate femoral vascular access. The new guidelines address this gap by recommending alternative access ...

The efficient architecture of our joints, which allows our skeletons to be flexible and sturdy, originated among our most ancient jawed fish ancestors, according to a study published February 25th in the open-access journal PLOS Biology by Neelima Sharma of the University of Chicago and colleagues. Synovial joints are a key feature of most vertebrate skeletons, providing more mobility and stability compared to other joint types. A synovial joint allows bones or cartilage to slide past each other with the aid of a lubricated cavity between them. These joints are present in land vertebrates and bony fish, suggesting this feature had evolved in the common ancestors of these groups, but ...

A world of microbes resides within the gut of every human being. This vast microbial community, the microbiome, which includes bacteria and viruses, has repeatedly demonstrated its ability to actively contribute to both health and disease. Researchers have learned a good deal about the bacterial communities that live in the human gut. For instance, they have discovered that these bacteria extensively metabolize the food we eat, drive normal development of the immune system and, to our detriment, include some opportunistic microorganisms that can cause disease under certain conditions. On the other hand, the contributions of viruses in the gut microbiome ...

WHAT: Lowering the body temperature of preterm infants (born at 33 to 35 weeks of pregnancy) with hypoxic ischemic encephalopathy (HIE)—a type of brain damage caused by oxygen loss—offers no benefits over standard care, according to a study funded by the National Institutes of Health (NIH). Previous studies of near-term and term infants (born after 36 weeks) with HIE found that this cooling treatment, which lowers body temperature to about 92 degrees Fahrenheit, significantly reduced the risk of death or disability by age 18 months (corrected for prematurity). However, the current findings show ...

BATON ROUGE – When faced with multiple food options and ultimately choosing one, the factors of that decision-making process may be more physiological than previously assumed. A group of scientists led by Pennington Biomedical Research Center’s Dr. Christopher Morrison recently discovered that the hormone fibroblast growth factor 21, or FGF21, plays an influential role in brain reward mechanisms like those involved in dietary choices.   The discovery was announced in the research team’s recent paper titled “FGF21 ...

Discarded food scraps, stray branches, seashells and many other natural materials are key ingredients in a new system that can pull drinkable water out of thin air developed by researchers from The University of Texas at Austin. This new “molecularly functionalized biomass hydrogels” system can convert a wide range of natural products into sorbents, materials that absorb liquids. By combining these sorbents with mild heat, the researchers can harvest gallons of drinkable water out of the atmosphere, even in dry conditions. “With ...

COLUMBUS, Ohio – Researchers have developed a battery that can convert nuclear energy into electricity via light emission, a new study suggests.  Nuclear power plants, which generate about 20% of all electricity produced in the United States, produce almost no greenhouse gas emissions. However, these systems do create radioactive waste, which can be dangerous to human health and the environment. Safely disposing of this waste can be challenging.  Using a combination of scintillator crystals, high-density materials that emit light when they absorb radiation, and solar cells, the team, led by researchers from The Ohio State University,  demonstrated that ambient ...

A novel tool for rapidly identifying the genetic “fingerprints” of cancer cells may enable future surgeons to more accurately remove brain tumors while a patient is in the operating room, new research reveals. Many cancer types can be identified by certain mutations, changes in the instructions encoded in the DNA of the abnormal cells. Led by a research team from NYU Langone Health, the new study describes the development of Ultra-Rapid droplet digital PCR, or UR-ddPCR, which the team found can measure the level of tumor cells in a tissue sample ...

WASHINGTON, Feb. 25, 2025 – Keeping work surfaces clean during meat processing is a challenge. Bacteria from meat can attach, grow, and build up to create a biofilm that is difficult to remove, even on stainless steel surfaces used in industrial facilities. It can also aggregate, clumping together into an invisible mass that is stronger than individual cells, making it harder to kill using food-grade antibacterial surface cleaners. In a paper published this week in Journal of Laser Applications, from AIP Publishing and the Laser Institute of America, researchers from the Hopkirk Research Institute, New Zealand Food Safety Science and Research Centre, ...

Barcelona, 25 February 2025 - Myeloid leukaemias are among the most aggressive blood cancers and have low survival rates. Today, leukaemia patients undergo genetic analysis to identify mutations and select the most appropriate treatment. However, even among patients with the same mutation, disease progression and response to therapy can vary significantly. A study led by ICREA researcher Dr. Alejo Rodríguez-Fraticelli at IRB Barcelona, and funded by Fundación CRIS contra el cáncer, has now revealed these differences can be explained by the fact that not all blood stem cells ...

Researchers from the Organoid group at the Hubrecht Institute have found that specific gut cells, BEST4/CA7+ cells, regulate electrolyte and water balance in response to bacterial toxins that cause diarrhea. Their findings, published in Cell Stem Cell, show that these cells greatly increase in number when exposed to the cytokine interferon-γ (IFNγ), presenting a promising target for therapeutic strategies. In the gut, a variety of cell types collaborate to keep a balance of electrolyte and water. Bacterial infections can disrupt this balance, leading ...

Working toward more effective tuberculosis (TB) vaccines, researchers at Weill Cornell Medicine have developed two strains of mycobacteria with "kill switches" that can be triggered to stop the bacteria after they activate an immune response. Two preclinical studies, published, Jan. 10 in Nature Microbiology, tackle the challenge of engineering bacteria that are safe for use in controlled human infection trials or as better vaccines. While TB is under control in most developed countries, the disease still kills over a million people a year worldwide. Spreading easily through ...
