Discovery of bacteria's defence against viruses becomes a piece of the puzzle against resistance

Antibiotic resistance is a global health challenge that could overtake cancer mortality within a few decades. In a new study, researchers at Umeå University, Sweden, show that the emergence of resistance can be understood in the mechanism of how bacteria build up defences against being infected by viruses. It is about genes in the bacterium that interfere with the attacking virus's ability to multiply. "A key to antibiotic resistance might be the use of viruses to kill bacteria, however, the systems that bacteria employ to defence themselves against viruses are unknown. Understanding these ...

Pre-eclampsia is associated with earlier onset and higher incidence of cardiovascular risk factors

Milan, Italy – 4 April 2025. Women who have experienced pre-eclampsia have accelerated accumulation of cardiovascular (CV) risk factors compared with women who had pregnancies without pre-eclampsia according to research presented today at ESC Preventive Cardiology 2025,1 a scientific congress of the European Society of Cardiology (ESC). Pre-eclampsia typically affects 2−5% of pregnant women and is broadly defined as the development of hypertension and high protein levels in the urine of a woman with previously normal blood pressure.2 ...

Warwick astronomers discover doomed pair of spiralling stars on our cosmic doorstep

University of Warwick astronomers have discovered an extremely rare, high mass, compact binary star system only ~150 light years away. These two stars are on a collision course to explode as a type 1a supernova, appearing 10 times brighter than the moon in the night sky. Type 1a supernovae are a special class of cosmic explosion, famously used as ‘standard candles’ to measure distances between Earth and their host galaxies. They occur when a white dwarf (the dense remnant core of a star) accumulates too much mass, is unable to withstand its own ...

Soil conditions significantly increase rainfall in world’s megastorm hotspots

Storm forecasting is traditionally based on studying atmospheric conditions but ground-breaking research that also looks at land surface conditions is set to transform early warning systems in tropical regions. This will enable communities to better adapt to the destructive impacts of climate change. The new study led by the UK Centre for Ecology & Hydrology (UKCEH) has shown that a large contrast in soil moisture levels over a range of hundreds of kilometres results in atmospheric changes that increase rainfall area and amount in several megastorm hotspots globally. This increase ranges from 10 to 30% depending on the region and size ...

Suspected fibrocartilaginous embolus in Asian small-clawed otter (Aonyx cinereus)

An 11-year-old neutered male Asian small-clawed otter fell down the stairs while sleeping, after which it developed left-sided paralysis. Initial treatment involved once daily administration of prednisolone at 0.5 mg/kg. Despite slight clinical sign improvements by day 10, paralysis persisted. MRI (T2WI) identified a well-defined, hyper-intense lesion on the left side within the spinal cord at the C2-3 intervertebral level. Based on CT and MRI findings, fibrocartilaginous embolus (FCE) was suspected. Prednisolone was then tapered and by day 23 of illness, the otter was able to walk ...

Enhancing heat transfer using the turbulent flow of viscoelastic fluids

Fluids play a crucial role in industrial processes like cooling, heating, and mixing. Traditionally, most industries would utilize Newtonian fluids—which have a constant viscosity—for such processes. However, many are now adopting viscoelastic fluids, which can behave as both liquids and elastic materials. These fluids can suppress turbulence in simple flows like straight pipes or channels, leading to reduced wall friction. This “drag reduction effect” has attracted significant interest due to its potential to enhance energy efficiency. To advance the industrial applications ...

Exercise as an anti-ageing intervention to avoid detrimental impact of mental fatigue

Retired people who habitually exercise are more able to fight the impacts of mental fatigue, new research suggests. In a paper published in the Journal of Aging and Physical Activity, a team of researchers from the University of Birmingham and the University of Extremadura in Spain worked with groups of adults to find out whether age would increase, and regular exercise would decrease the impact of mental fatigue on a series of cognitive and physical performance tests. In the first study, sedentary men between 65 and 79 performed worse in cognitive and physical tests compared to 52-64 year olds, with these ...

New guidelines aim to improve cystic fibrosis screening

All states should adopt updated screening protocols so more newborns with cystic fibrosis can be diagnosed in the first weeks of life, when interventions can have the greatest benefit, according to the Cystic Fibrosis Foundation guidelines published April 2 in the International Journal of Neonatal Screening. Current newborn screening protocols vary across states. Some states use outdated protocols that often miss cases of the inherited disease, especially in newborns with Black, Hispanic and Asian, as well as American Indian and multiracial ancestry, said ...

Picky eaters by day, buffet by night: Butterfly, moth diets sync to plant aromas

UNIVERSITY PARK, Pa. — The scent of blooming flowers and fresh plant life is not just a perk of springtime; it is a key driver in the survival and evolution of butterflies and moths. New research led by scientists at Penn State reveals how the daily cycles of plant aromas are linked to the dietary habits and evolution of the winged insects collectively known as Lepidoptera. In a recent study published in the journal Proceedings of the Royal Society B, an international team of researchers tested a new hypothesis for why some Lepidoptera have very specific diets, feeding on only a few types ...

Researchers’ 3D-printing formula may transform future of foam

From seat cushions to mattresses to insulation, foam is everywhere — even if we don’t always see it. Now, researchers at The University of Texas at Dallas have fused chemistry with technology to create a 3D-printed foam that is more durable and more recyclable than the polymer foam found in many everyday products. The research, which appears in the March 1 print edition of RSC Applied Polymers, a journal of the Royal Society of Chemistry, focused on creating a sturdy but lightweight foam that could be 3D-printed, a method that is still largely unexplored in commercial manufacturing, said the study’s co-lead author, UT Dallas doctoral student Rebecca Johnson ...

Nurture more important than nature for robotic hand

How does a robotic arm or a prosthetic hand learn a complex task like grasping and rotating a ball? The challenge for the human, prosthetic or robotic hand has always been to correctly learn to control the fingers to exert forces on an object. The sensitive skin and nerve endings that cover our hands have been attributed with helping us learn and adapt our manipulation, so roboticists have insisted on incorporating sensors on robotic hands. But–given that you can still learn to handle objects with gloves on– there must be something else at play. This mystery is what inspired researchers in the ValeroLab in the Viterbi School of Engineering ...
