A UC Riverside-led study has found that a smartphone app that tracks household water use and alerts users to leaks or excessive consumption offers a promising tool for helping California water agencies meet state-mandated conservation goals. Led by Mehdi Nemati, an assistant professor of public policy at UCR, the study found that use of the app—called Dropcountr—reduced average household water use by 6%, with even greater savings among the highest water users. Dropcountr works by interpreting water-use data from smart water meters, which many utilities originally ...

Scientists have found that global warming in the Middle East and North Africa is making breast, ovarian, uterine, and cervical cancer more common and more deadly. The rise in rates is small but statistically significant, suggesting a notable increase in cancer risk and fatalities over time.   “As temperatures rise, cancer mortality among women also rises — particularly for ovarian and breast cancers,” said Dr Wafa Abuelkheir Mataria of the American University in Cairo, first author of the article in Frontiers ...

How long have you been doing your current job? Have you ever thought about trying a new profession? How difficult does change seem to you? The current rapid transformation of the labor market is putting many workers to the test: they struggle to keep up and move into new roles, while at the same time companies are having difficulty finding qualified personnel. A new study has analyzed the French labor market using methods from statistical physics, and found that over 90% of jobs today function as bottlenecks: they are easily accessible, but once entered, they become traps from which ...

Milan, Italy: Pharmacogenomics studies how individuals respond to drugs based on their genetic code. Using that knowledge to guide prescribing in routine care could lead to better outcomes for patients and save money for health systems. Generating pharmacogenomic data in the laboratory is relatively straightforward, but a major challenge is making that information available to frontline healthcare professionals in a clinically relevant format and timeframe. This has meant that, to date, only a limited numbers of patients have been able to benefit from such individually optimised treatments. Dr John McDermott, ...

How does a bird learn its birdsong? Tomoko Fujii and Masashi Tanaka, from Waseda University, explored what drives a zebra finch to approach and imitate other zebra finches to learn its birdsong in a new JNeurosci paper.  The researchers explored song learning in young male zebra finches as they interacted with “tutor” adults that already knew their birdsongs. Young zebra finches preferably approached tutors that sang longer but less frequently. Fujii and Tanaka next probed the role of a brain region traditionally linked to emotions in mammals (the amygdala) in this song-learning process. To examine the ...

Background and objectives Lung Squamous cell carcinoma (LSCC) represents the second most common non-small cell lung cancer. Although studies identified adenocarcinoma-like driver mutations in LSCC using next-generation sequencing (NGS), the disease is challenging to treat due to the limited number of detectable mutations for targeted drug therapy. This study aimed to evaluate the mutation profiles of LSCC detected by NGS to assess the relationships between different driver mutations and clinicopathological parameters. Methods NGS ...

FRANKFURT. Otodus megalodon was the largest predatory fish in Earth’s history: Measuring up to 24 meters, it was longer than a truck with a trailer and weighed almost twice as much. Embedded in its jaws were triangular teeth the size of a hand, and its bite had the force of an industrial hydraulic press. It swam through the world’s oceans between 20 and 3 million years ago, frequently on the hunt for prey to satisfy a calorie demand as vast as its size: According to estimates, it required around 100,000 kilocalories per day. Science widely assumed that megalodon’s main calorie intake was in the form of ...

Toronto, ON – Climate change and extreme weather events are threatening the sexual and reproductive health (SRH) of young adolescents in Kenya, according to a new study published earlier this month in BMJ Global Health. The study reveals that food, water, and sanitation insecurities are placing young adolescents aged 10-14, especially girls, at increased risk of school dropout, transactional sex, gender-based violence, and early pregnancy. “Climate change isn’t just an environmental issue, it’s an urgent public health ...

Males are more than four times more likely to receive an autism diagnosis than females. But a new study by researchers at UC San Diego School of Medicine has found no clinical differences in autistic traits between the sexes in toddlers when they are first diagnosed with autism. The study was published in Nature Human Behavior on May 26, 2025. The findings have potential implications for early diagnosis and intervention for autistic children. Between 2002 and 2022, the researchers assessed more than 2,500 male and female toddlers between 12 and 48 months of age. Of these toddlers, 1,500 were ...

Africa's predominantly rainfed agricultural sector is highly vulnerable to erratic rainfall and the impacts of climate change. Despite having significant irrigation potential, only a small fraction of Africa’s arable land is currently equipped for irrigation. A new policy brief by the United Nations University Institute for Water, Environment and Health (UNU-INWEH) - Implementing the IDAWM Framework to Enhance Agricultural Water Management in the African Union – developed in collaboration with Centre on Climate Change & Planetary Health of London School of Hygiene and Tropical Medicine, International ...

Milan, Italy: A new, rapid testing method will greatly help the diagnosis of rare diseases in babies and children, according to research to be presented to the annual conference of the European Society of Human Genetics today (Monday). While rare genetic diseases are uncommon, as their name suggests, there are more than 7,000 types of disease caused by mutations in more than 5,000 known genes, affecting approximately 300 million individuals worldwide. Currently about half of all patients with a suspected rare disease remain undiagnosed and existing testing methods for undiagnosed conditions are typically slow, ...

Milan, Italy: Neuropathy, a disorder in which damage to nerves can impair sensation and movement, has many causes, including infection1. Now, researchers from the UK have identified distinct genetic changes in a newly-discovered neuropathy and believe that their work will provide insights into the causal mechanism and why some previously healthy people develop neuropathies after infection whereas others do not. Dr Rob Harkness, a postdoctoral research Fellow at the University of Manchester, Manchester, UK, will tell the annual ...

In recent years, the concept of "rewilding" has risen to prominence in the conservation community, but to date, most efforts have been concentrated on large protected areas far from cities—and consequently, far from urban areas suffering pronounced biodiversity losses. In a recently published BioScience article, Patrick Finnerty (University of Sydney) and colleagues make the case for "urban rewilding" as a vital approach for addressing biodiversity losses, focusing on the rapidly expanding cities that are soon expected to be home to ...

A gene that regulates the development of roots in vascular plants is also involved in the organ development of liverworts — land plants so old they don’t even have proper roots. The Kobe University discovery highlights the fundamental evolutionary dynamic of co-opting, evolving a mechanism first and adopting it for a different purpose later. When scientists discover that a gene is necessary for the development of a trait, they are quick to ask since when this gene has been involved in this and how the evolution of the gene has ...

The murder of George Floyd could have been avoided if police had responded to the concerns of bystanders reveals research led by Lancaster University. George Floyd was murdered by Minneapolis police officer Derek Chauvin on May 25 2020. For the first time, psychologists have analysed 12 videos recorded on the body-worn cameras of the attending officers, the smartphones of bystanders and local CCTV cameras from 19:55 until 20:42 (CST) on the date of his death. Their research published in American Psychologist examines the range of verbal and physical ...

Researchers at the School of Engineering of the Hong Kong University of Science and Technology (HKUST) have developed a novel elastic alloy called Ti₇₈Nb₂₂, which achieves remarkable efficiency for solid-state heat pumping and exhibits a reversible temperature change (ΔT) ability that is 20 times greater than that of conventional metals when stretched or compressed, offering a promising green alternative to traditional vapor-compression heating and cooling technologies. Nearly half of the world’s energy is consumed for heating, including district heating in the building sector and process heating in various industrial sectors. Currently, global heat ...

Children born before 37 weeks of gestation have a considerably increased risk of dying before they reach the age of five. Predicting the risk of preterm birth (PTB) and hence implementing preventive strategies is complicated by the heterogeneity of the condition, the many unknown mechanisms involved, and the lack of reliable predictive tools. Now, however, researchers have been able to show that blood cell-free RNA (cfRNA) signatures can predict PTB over four months before delivery date, the annual conference of the European Society of Human Genetics will hear ...

Lorundrostat, a novel therapy which blocks the production of aldosterone from the adrenal glands, demonstrated clinically meaningful and sustained reductions in blood pressure in 1,083 patients with uncontrolled or resistant hypertension, according to the results of a phase 3 trial announced today.  LONDON, UK – 24 May 2025 – The data from the Launch-HTN trial, announced at the 34th European Meeting on Hypertension and Cardiovascular Protection, show that lorundrostat, an aldosterone synthase inhibitor, is ...

A case in which a sperm donor was later found to be carrying a cancer-causing pathogenic variant in his gametes has highlighted the problems of regulating gamete donation at European and international level, the annual conference of the European Society of Human Genetics will hear today (Saturday). Dr Edwige Kasper, a specialist in genetic predisposition to cancer at the Rouen University Hospital, Rouen, France, will say that the lack of cross-border regulation in Europe can result in the multiple use of gametes in  families and risks inbreeding and the  abnormal  dissemination of inherited diseases. Towards ...

In biology, enzymes have evolved over millions of years to drive chemical reactions. Scientists from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) now derived universal rules to enable the de novo design of optimal enzymes. As an example, they considered the enzymatic reaction of breaking a dimer into two monomer molecules. Considering the geometry of such an enzyme-substrate-complex, they identified three golden rules that should be considered to build a functional enzyme. First, the interface of both enzyme and molecule should be located at their respective smaller end. This way, a strong coupling between both of them ...

Q: How would you summarize your study for a lay audience? Our study investigated the role of astrocytes, an abundant cell type in the brain, in regulating an immune response against glioblastoma (GBM)—a highly aggressive brain cancer. We found a subset of astrocytes that limits the immune response and can be targeted with therapeutics.   Q: What question were you investigating? GBM is a brain cancer that has remained untreatable for decades. Immunotherapies that have worked in other cancers are ineffective in GBM, potentially due to the local suppression of immune responses in the tumor microenvironment. Astrocytes are abundant ...

HOUSTON – (May 23, 2025) – More than ten years ago, researchers at Rice University led by materials scientist Boris Yakobson predicted that boron atoms would cling too tightly to copper to form borophene, a flexible, metallic two-dimensional material with potential across electronics, energy and catalysis. Now, new research shows that prediction holds up, but not in the way anyone expected. Unlike systems such as graphene on copper, where atoms may diffuse into the substrate without forming a distinct alloy, the ...
