Beyond photorespiration: A systematic approach to unlocking enhanced plant productivity
2025-04-04
A groundbreaking study published in Science Advances has revealed promising strategies to significantly improve crop yields by addressing photorespiration, a metabolic process that can reduce productivity by up to 36% in some crops. Researchers from the University of Groningen and Heinrich Heine University Düsseldorf, working as part of the GAIN4CROPS project (gain4crops.eu), have evaluated several alternative pathways that could help overcome this major agricultural bottleneck.
Photorespiration occurs when the enzyme RuBisCO, essential for photosynthesis, reacts with oxygen instead of carbon dioxide, resulting ...
How a small number of mutations can fuel outbreaks of western equine encephalitis virus
2025-04-04
New research shows how small shifts in the molecular makeup of a virus can profoundly alter its fate. These shifts could turn a deadly pathogen into a harmless bug or supercharge a relatively benign virus, influencing its ability to infect humans and cause dangerous outbreaks.
This is the latest finding in a series of studies led by Jonathan Abraham, associate professor of microbiology in the Blavatnik Institute at Harvard Medical School, and his team that aim to understand the risk of western equine encephalitis virus and related viruses. The work, which was supported ...

Many older adults send their doctors portal messages, but who pays?
2025-04-04
When today’s older adults were growing up, the only way to get information to your doctor or their clinic was a phone call. And getting more than a simple answer probably meant going in for an appointment.
But a new study suggests that people in their 50s and older have embraced the ability to send and receive secure medical messages with their doctors and other providers, through the digital patient portals that most health systems and medical offices now offer.
The study also suggests that some older adults – including those with very low incomes – find themselves getting billed for ...

Gender inequity in institutional leadership roles in US academic medical centers
2025-04-04
About The Study: This systematic scoping review suggests that even though emphasis has been placed on addressing gender inequities in academic medicine, considerable disparities remain at the leadership level. While certain positions and specialties have been observed to have more female leaders, niches of academic medicine almost or completely exclude women from their leadership ranks. Importantly, even female-dominated specialties, such as obstetrics and gynecology, have substantial inequity in leadership roles. It is past time for organizational and systems-level changes to ensure equitable ...
Pancreatic cells ‘remember’ epigenetic precancerous marks without genetic sequence mutations
2025-04-04
FOR IMMEDIATE RELEASE
Johns Hopkins Medicine scientists say they have found a pattern of so-called epigenetic “marks” in a transition state between normal and pancreatic cancer cells in mice, and that the normal cells may keep at least a temporary “memory” of those cancer-linked marks.
Epigenetic marks are chemical modifications that help regulate genetic expression without directly altering DNA sequence in the makeup of genes. While the genetic code is like a computer’s hardware, epigenetics involves chemical marks on top of the genetic code that act as software programing in a computer.

Discovery of bacteria's defence against viruses becomes a piece of the puzzle against resistance
2025-04-04
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 ...

Warwick astronomers discover doomed pair of spiralling stars on our cosmic doorstep
2025-04-04
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
2025-04-04
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)
2025-04-04
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
2025-04-04
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
2025-04-04
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 ...
