An enemy within: Pathogens hide in tissue
Antibiotics cure many bacterial infections. However, some patients suffer a relapse. A research group at the University of Basel has now discovered why some bacteria can survive antibiotic therapy. The team uncovered where the bacteria hide in the bo.....»»
Pathogens that cling to microplastics may survive wastewater treatment
Wastewater treatment fails to kill several human pathogens when they hide out on microplastics in the water, reports a study led by Ingun Lund Witsø of the Norwegian University of Life Sciences, published November 6, 2024 in the open-access journal.....»»
NRO chief: “You can’t hide” from our new swarm of SpaceX-built spy satellites
"A satellite is always coming over an area within a given reasonable amount of time." The director of the National Reconnaissance Office has a message for US adversaries around th.....»»
Scientists shed light on an arms race between barley and a fungal pathogen
Scientists from the Leibniz Institute of Plant Biochemistry (IPB), together with partners from the University of Cologne, have discovered a new group of defense substances in barley that are effective against a broad spectrum of fungal pathogens. One.....»»
Space Innovation Lab experiment heads to International Space Station
The first human tissue samples from Oxford's Space Innovation Lab (SIL) have been launched and are on their way to the International Space Station, where they will be used to study the effects of space microgravity on the human aging process......»»
New nanocatalyst targets tumors without oxygen
Tumors often contain areas of oxygen-deficient tissue that frequently withstand conventional therapies. This is because the drugs applied in tumors require oxygen to be effective. An international research team has developed a novel mechanism of acti.....»»
Scientists describe how mycobacteria evade the effects of antibiotics
One of the main challenges of contemporary medicine is posed by the resistance of pathogens to antibiotics. An important step in countering it has now been made by researchers from IOCB Prague, in collaboration with colleagues from the Institute of M.....»»
Scientists uncover key mechanism in pathogen defense, paving way for new antimicrobial strategies
Researchers have made a significant breakthrough in understanding how certain pathogens defend themselves against the host's immune system......»»
COVID lessons learned? UN summit mulls plan for healthy planet, and humans
The COVID-19 and Ebola outbreaks brought into stark relief the harms that can come to humans if we interfere too much with nature, placing ourselves in contact with animals carrying unknown pathogens......»»
When things get tight: How does the embryo in rapeseed react to mechanical constraints?
In 2021, the Nobel Prize in Physiology or Medicine was awarded for elucidating the biology of mechanosensors. These discoveries revealed how mechanical forces generated by touch influence tissue differentiation and morphogenesis in animals and humans.....»»
Warming lakes and rivers may spread fish pathogens
Michigan's rivers and lakes were once cold enough that fish were protected from some infection-causing parasites. As the Great Lakes ecosystem warms, a Michigan State University researcher is investigating new pathogens that may become relevant to th.....»»
Biologist finds new ways to study snake venom
Dutch biologist Mátyás Bittenbinder developed new, non-animal methods to investigate tissue-damaging snake venom. In this way, he hopes to contribute to solutions for victims. Millions of people are bitten by venomous snakes every year. Of these, 4.....»»
Polar bears" exposure to pathogens is increasing as their environment changes, blood samples suggest
As the Arctic warms, polar bears now face a greater risk of contracting several pathogens than bears three decades ago. Karyn Rode and Caroline Van Hemert of the U.S. Geological Survey report these findings in a new study published October 23, 2024,.....»»
Experiments find people assume unidentified bystanders in a war zone are combatants, acceptable collateral damage
People's bias toward sacrificing unknown bystanders appears to stem from assuming the unidentified person is an enemy, according to a study published October 23, 2024, in the open-access journal PLOS ONE by Scott Danielson from the University of Cant.....»»
Uncovering new regulatory mechanisms in embryo implantation
Implantation is the initial step in pregnancy, where the embryo attaches to and enters the endometrium, the inner tissue layer of the uterus. During this process, the cells of the endometrium change to build the right conditions for the fertilized eg.....»»
Trump’s Racist Rants against Immigrants Hide under the Language of Eugenics
Anti-immigrant rhetoric in the U.S. comes straight out of the playbook of eugenics, deeply dishonest scientism that criminality, poverty and a host of other ills were all genetically inherited.....»»
New web platform provides global mapping of freshwater crayfish and pathogens
Freshwater crayfish, keystone species of aquatic ecosystems, are now at the center of a new tool that promises to revolutionize conservation efforts. World of Crayfish (WoC), a newly launched web platform, aims to provide real-time global mapping of.....»»
Scientists develop a new method to study gene function in cells and tissue
The Gaublomme lab has developed a new optical pooled screening approach called CRISPRmap, which enables the coupling of optical properties of single cells to targeted genetic perturbations. Optical phenotypes are typically inaccessible for sequencing.....»»
Scientists discover how innate immunity envelops bacteria
The protein GBP1 is a vital component of our body's natural defense against pathogens. This substance fights against bacteria and parasites by enveloping them in a protein coat, but how the substance manages to do this has remained unknown until now......»»
Expansion technique to image nanoscale structures inside cells makes high-resolution imaging more accessible
A classical way to image nanoscale structures in cells is with high-powered, expensive super-resolution microscopes. As an alternative, MIT researchers have developed a way to expand tissue before imaging it—a technique that allows them to achieve.....»»
Targeting "selfish" bacteria could optimize inhibitors that fight antibiotic resistance
As strains of pathogens resistant to frontline antibiotics become more common worldwide, clinicians are more often turning to combination treatments that degrade this resistance as a first treatment option......»»
