Hodgkin’s lymphoma: Small change, big effect

Hodgkin’s lymphoma is one of the most common types of lymphoma in young adults. It is characterized by the presence of enlarged B lymphocytes, which are unusual in that they bear on their surface the identifying markers of many other immune cells – such as those found on phagocytes, dendritic cells, or T cells. Now, a team led by Stephan Mathas from the Experimental and Clinical Research Center (ECRC) has explained how these changes take place in the cells and what impact they have. The ECRC is a joint institution of the Max Delbrück Center and Charité – Universitätsmedizin Berlin. “Many different ...

How animals get their stripes and spots

Nature has no shortage of patterns, from spots on leopards to stripes on zebras and hexagons on boxfish. But a full explanation for how these patterns form has remained elusive. Now engineers at the University of Colorado Boulder have shown that the same physical process that helps remove dirt from laundry could play a role in how tropical fish get their colorful stripes and spots. Their findings were published Nov. 8 in the journal Science Advances. “Many biological questions are fundamentally ...

A fifth of European Red List flora and fauna species may be at risk of extinction

A new analysis of 14,669 threatened species of plants and animals found in Europe reveals that about one fifth face the risk of extinction, and that agricultural land-use change poses a significant threat to these species. Axel Hochkirch of the Musée National d’Histoire Naturelle, Luxembourg, and colleagues present these findings in the open-access journal PLOS ONE on November 8, 2023. The variety of species of living things—biodiversity—is declining around the world, as more and more species face the risk of extinction. Many efforts, including some by governments and nonprofit organizations, aim to reduce the loss ...

Head lice evolution mirrors human migration and colonization in the Americas

A new analysis of lice genetic diversity suggests that lice came to the Americas twice – once during the first wave of human migration across the Bering Strait, and again during European colonization. Marina Ascunce, currently at the USDA-ARS, and colleagues, report these findings in a new study published November 8 in the open-access journal PLOS ONE. The human louse is a wingless, blood-sucking parasite that lives its entire life on its host. It is one of the oldest known parasites to live on humans, and the two species have coevolved ...

Autism brain states hold the key to unlocking childhood memories

Neuroscientists have discovered a fascinating connection between the retention of early life memories and brain developmental trajectories associated with autism [Wednesday 8th November 2023]. Most of us remember little of our experiences from before two years of age. This form of memory loss, termed “infantile amnesia” refers to the seemingly complete loss of episodic and autobiographical memories formed during early life. The research team at Trinity College Dublin investigated how infantile amnesia is affected by forms of autism. The maternal immune response, sparked into life in response to infection during pregnancy, ...

Artificial bladders shine light on bugs that cause urinary tract infections

The research, published today in Science Advances, is the first to use a sophisticated human tissue model to explore the interaction between host and pathogen for six common species that cause urinary tract infections. The findings suggest that the ‘one size fits all’ approach to diagnosis and treatment currently used in most healthcare systems is inadequate. Urinary tract infection (UTI) is a growing problem, with around 400 million global cases per year and an estimated 250,000 UTI-related deaths associated with antimicrobial resistance ...

Temperature increase triggers the viral infection

Researchers at Lund University, together with colleagues at the NIST Synchrotron Facility in the USA, have mapped on an atomic level what happens in a virus particle when the temperature is raised. "When the temperature rises, the virus's genetic material changes its form and density, becoming more fluid-like, which leads to its rapid injection into the cell," says Alex Evilevitch a researcher at Lund University who led the study. Viruses lack their own metabolism and the ability to replicate independently; they are entirely dependent on a host cell to multiply. Instead, the virus hijacks the internal machinery of the infected cell ...

Molecule tested at University of São Paulo, in Brazil, proves able to mitigate heart failure

Researchers at the University of São Paulo (USP) in Brazil, partnering with Foresee Pharmaceuticals, a Taiwan and US-based biopharmaceutical company, have tested a synthetic molecule for the treatment of heart failure. The study, funded by FAPESP, was published yesterday (11/07/2023) in the European Heart Journal. The theme was also highlighted in the magazine's editorial. Heart failure is a condition in which the heart muscle cannot pump enough blood to meet the body's needs for blood and oxygen. It causes more deaths worldwide than any other disease, in the sense that other cardiovascular disorders ...

How mice choose to eat or to drink

Making decisions is hard. Even when we know what we want, our choice often leaves something else on the table. For a hungry mouse, every morsel counts. But what if the decision is more consequential than choosing between crumbs and cheese? Stanford researchers investigated how mice resolve conflicts between basic needs in a study published in Nature on Nov. 8. They presented mice that were both hungry and thirsty with equal access to food and water and watched to see what happened next. The behavior of the mice surprised the scientists. Some gravitated first ...

Plant lifecycle insights: Big data can predict climate change impact

The study is based on a new database created by the researchers which combines, for the first time, datasets on distribution and datasets on lifecycles, making it possible to establish the prevalence of different lifecycles around the globe. It uses empirical tools and big data to examine theoretical paradigms about the way in which human disturbance is affecting annual plants and their global distribution. Among other things, it was found that annuals are expected to benefit more with the rise in human population density and due to climate change, which ...

Physicists trap electrons in a 3D crystal for the first time

Electrons move through a conducting material like commuters at the height of Manhattan rush hour. The charged particles may jostle and bump against each other, but for the most part they’re unconcerned with other electrons as they hurtle forward, each with their own energy. But when a material’s electrons are trapped together, they can settle into the exact same energy state and start to behave as one. This collective, zombie-like state is what’s known in physics as an electronic “flat band,” and scientists predict that when electrons are in this state they can start to ...

Scientists tame biological trigger of deadly Huntington’s disease

Huntington’s disease causes involuntary movements and dementia, has no cure, and is fatal. For the first time, UC Riverside scientists have shown they can slow its progression in flies and worms, opening the door to human treatments. Key to understanding these advancements is the way that genetic information in cells is converted from DNA into RNA, and then into proteins. DNA is composed of chemicals called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The order of these nucleotides determines what biological instructions are contained in a strand of DNA. On occasion, some DNA nucleotides repeat themselves, ...

Disturbances in sensory neurons may alter transient pain into chronic pain

Utrecht, November 8, 2023 - Researchers from the Center for Translational Immunology at University Medical Center Utrecht (the Netherlands) have identified that a transient inflammatory pain causes mitochondrial and redox changes in sensory neurons that persist beyond pain resolution. These changes appear to predispose to a failure in resolution of pain caused by a subsequent inflammation. Additionally, targeting the cellular redox balance prevents and treats chronic inflammatory pain in rodents. Pain often persists in patients with an ...
