(Press-News.org) In a study published in Weather, researchers estimated the current chances and characteristics of extreme hot episodes in the UK, and how they have changed over the last 6 decades.
The team found that temperatures several degrees above those recorded during the UK’s heatwave in July 2022 are plausible in today’s climate, with a simulated maximum of over 45°C (113°F). The likelihood of 40°C (104°F) is now over 20 times more likely than it was in the 1960s. Moreover, the chance of 40°C will likely continue to rise as the climate warms. The investigators estimate that there is approximately a 50% chance of again exceeding 40°C in the next 12 years.
Through multiple storylines of how temperatures could evolve through the summer season, they also found that prolonged heatwaves of over a month above 28°C (82°F) are possible in southeast England today. These storylines are valuable for modeling and stress testing.
“Our findings highlight the need to prepare and plan for the impacts of rising temperatures now, so we can better protect public health, infrastructure, and the environment from the growing threat of extreme heat,” said corresponding author Gillian Kay, PhD, of the Met Office Hadley Centre.

Tumor DNA analysis for every child in the Princess Máxima Center
2025-06-18
Readouts of the full DNA of children with cancer at diagnosis have been implemented as the standard of care in a European first. By determining a child's type of cancer as precisely as possible, the Princess Máxima Center for pediatric oncology aims to offer each individual child the treatment most likely to work for them.
To determine the precise form of childhood cancer, the DNA in children’s tumor cells is analyzed at diagnosis. Since May, the Princess Máxima Center has started analyzing all children’s complete tumor DNA as standard of care, using a ...
To encourage scientific thinking, it is better to instruct than to reward
2025-06-18
People are generally very good at detecting cause-effect relationships. This ability helps us understand the world, learn, make decisions, and predict the future. In short, it helps us adapt and survive. In fact, we are so good at spotting causal patterns that sometimes we find connections that don't really exist. As a result, we fall into the so-called causal illusion, i.e., we mistakenly believe that one event causes another, when, in fact, both are unrelated. A typical example occurs in the field of health when we assume that a pseudoscientific treatment is effective (therefore, ...
Sevenfold boost in lifespan of anode-free all-solid-state batteries using MoS₂ thin films
2025-06-18
South Korean researchers have developed a technology that improves the lifespan of next-generation anode-free all-solid-state batteries (AFASSBs) by sevenfold using a cost-effective two-dimensional material.
A collaborative team led by Dr. Ki-Seok An and Dr. Dong-Bum Seo of the Korea Research Institute of Chemical Technology (KRICT), along with Prof. Sangbaek Park’s group at Chungnam National University, successfully enhanced the durability of AFASSBs by applying a molybdenum disulfide (MoS₂) sacrificial layer grown via metal–organic chemical vapor deposition ...
Ancient groundwater records reveal regional vulnerabilities to climate change
2025-06-18
Woods Hole, Mass. (June 17, 2025) — During the last ice age, storms soaked the now-arid Southwestern U.S., while today’s rainy Pacific Northwest remained relatively dry. As global temperatures rose and ice sheets retreated, those storms shifted north—reshaping the climate patterns that define both regions today.
New research published in Science Advances reveals that groundwater levels responded differently in the two regions during this dramatic shift. While the Pacific Northwest saw little change in water table depth despite increased rainfall, the Southwest experienced significant groundwater loss. The ...
New monstersaur species a ‘goblin prince’ among dinosaurs
2025-06-18
A newly discovered, raccoon-sized armored monstersaurian from the Grand Staircase-Escalante National Monument in Southern Utah, United States, reveals a surprising diversity of large lizards at the pinnacle of the age of dinosaurs. Named for the goblin prince from J.R.R. Tolkien’s “The Hobbit,” the new species Bolg amondol also illuminates the sometimes-murky path that life traveled between ancient continents.
“I opened this jar of bones labeled ‘lizard’ at the Natural History Museum of Utah, and was like, oh wow, there's a fragmentary skeleton here,” said lead author Hank Woolley ...
Father-daughter bonding helps female baboons live longer
2025-06-18
Besides humans, very few mammals receive care from their fathers. But when species do, it may benefit their children.
New research from the University of Notre Dame found that the strength of early-life father-daughter relationships predicts meaningful differences in the survival of female baboons.
Published in Proceedings of the Royal Society B, the study evaluated the impact father baboons may have when they choose to co-reside or interact with their daughters, even though baboon mothers provide all essential care. Until now, the consequences of early-life paternal relationships of offspring were mostly unknown.
“Male baboons tend ...

Published in the open-access journal Royal Society Open Science, the collaborative research led by the Natural History Museum of Los Angeles County’s Dinosaur Institute reveals hidden treasures awaiting future paleontologists in the bowels of museum ...
Puberty blockers do not cause problems with sexual functioning in transgender adults
2025-06-18
During puberty, all kinds of hormonal changes take place in the body, which lead to the development of external sexual characteristics, such as breast growth, a lower voice or body hair growth. For transgender young people, who do not identify with the gender assigned to them at birth, these are often undesirable changes, which can be very drastic. Puberty blockers can temporarily halt these developments and give young people time to explore their gender identity. Although puberty blockers have been proven to contribute to the mental well-being of transgender young people, little is known about the influence of puberty blockers on sexual satisfaction and sexual problems later ...
High levels of antihistamine drugs can reduce fitness gains
2025-06-17
For some, the word “histamine” might evoke thoughts of seasonal allergies: runny noses, scratchy throats and itchy eyes. But the molecule also influences exercise performance.
A new study from the University of Oregon underscores its beneficial role in aerobic activity and exercise recovery, showing that blocking histamine at high levels interferes with fitness gains. It remains to be seen if lower-dose, over-the-counter antihistamine drugs have the same effect.
The study was published May 30 in the Journal of Applied Physiology.
Histamine is a small signaling molecule that evolved long ...
‘Virtual ward’ bed uses 4 times less carbon than traditional inpatient bed
2025-06-17
A virtual ward bed uses 4 times less carbon than a traditional inpatient bed, so helping the NHS achieve its net zero target by 2045, finds the first study of its kind, published in the open access journal BMJ Innovations.
And they are a promising way to care for more patients effectively, with the potential to reduce the need to build more high-carbon impact hospitals, suggest the researchers.
A virtual ward, also known as "hospital at home," provides hospital-level care to patients in the comfort of their own homes, leveraging digital technology and remote monitoring.
In recent years, particularly ...
