Recurring high-energy flood events are not the exception in the Ahr valley, but the rule - over periods of centuries to millennia. This is shown by a study just published in the scientific journal "Earth Surface Processes and Landforms" under the leadership of the University of Leipzig. The river sediments examined document the summer flood of 2021 as well as at least three other flood events in the past 1,500 years, which - measured by sedimentological parameters - were of comparable magnitude.

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires precise coordination; otherwise, the embryo could develop serious complications.

A University of Bonn study has shown how a maize pest is hijacking the plant's root-building function When a maize plant is attacked by the fungus Ustilago maydis, tumor-like tissue growths occur at the site of infection. How the pathogen causes this response in its host has long been unknown. But a University of Bonn study has now shown how the fungus takes over the plant's function for forming lateral roots.

Ovarian cancer often forms secondary tumors, especially in a certain tissue in the abdominal cavity known as the omentum. Researchers from the University of Basel and University Hospital Basel have investigated what happens when the cancer "hijacks" this organ. It is hoped their findings will lead to more successful treatments.

Researchers have developed formulations for the kind of paper used in cash receipts or shipping tags using wood-based chemicals that reduces reliance on toxic bisphenols while keeping print performance. Every day, millions of people use thermal paper without thinking about it. Receipts, shipping labels, tickets, and medical records all rely on heat-sensitive coatings to make text appear.

Why does one woman spontaneously conceive twins while another never does? That question is central to the of behavioral geneticist Nikki Hubers.

An infraslow brain and body rhythm, specific to the deep sleep of mammals, has recently been identified in seven reptile and one bird species, thus demonstrating its ancestral and fundamental character.

Ceramics are one of the most important sources of information for archaeologists. Yet how these objects are produced, especially in the firing stage, has received little attention to date. The excavation of a well-preserved pottery workshop at one of the most significant archaeological sites in Iraq-s Kurdistan region now offers the opportunity for an integrated analysis of an entire local production chain.

A new study involving the Medical University of Vienna shows how the multi-resistant fungus Candida auris utilises carbon dioxide (CO2) to survive on the skin and become resistant to antifungal therapies. The research team identified several new targets that could be used in the future to curb the spread and infections caused by Candida auris.

A major review of prior research has found no evidence that menopause hormone therapy either increases or decreases dementia risk in post-menopausal women, in a new study led by UCL researchers. The findings, commissioned by the World Health Organisation (WHO) and published in The Lancet Healthy Longevity , add much-needed clarity to a hotly-debated topic, and reinforce current clinical guidance that menopause hormone therapy, also called hormone replacement therapy or HRT, should be guided by perceived benefits and risks and not for dementia prevention.

The urgency of the climate crisis demands rapid innovation. Manchester researchers are using AI to assess climate remediation techniques, generating evidence faster to accelerate the development of promising technologies. Can we find ways to lock away carbon at the scale needed to fight climate change? There are lots of promising ideas which can make significant impacts at scale, such as ocean fertilisation, ocean alkalinity enhancement, enhanced rock weathering with croplands - but field trials at scale are slow, expensive and come with potential environmental risks.

Researchers have discovered how cells help keep their protein levels steady even when their ability to make new proteins changes. The finding could shed light on how our bodies stay resilient when nutrients and other resources rise and fall. Every cell depends on proteins to function and stay healthy.

Behind the decorations and happy faces, many parents experience the holiday season under intense pressure.

This type of information leads more people to believe that an alcoholic product is not harmful to their health Are you concerned that your alcohol consumption is damaging your health, and believe that an alcoholic beverage with a nutrition facts panel is a better choice than one without?

For years, researchers have been investigating a molecular complex that plays a key role in protein synthesis. They have now discovered that this complex also contributes a crucial function in ensuring that our DNA is properly processed and "packaged". The protein factories in our cells - so-called ribosomes - have a central task: during a process known as translation, amino acids are linked together according to messenger RNA, forming a growing peptide chain that later folds into a functional protein.

A breakthrough development in nanofabrication could help support the development of new wireless, flexible, high-performance transparent electronic devices. Researchers from the University of Glasgow's James Watt School of Engineering have developed a new method of interfacial imprinting ultra-thin nanowires onto bendable, transparent polymeric substrates.

Researchers identify the role of a key enzyme in rotavirus and norovirus infection, the leading causes of acute gastroenteritis A research team led by professor Jesús Rodríguez from the University of Valencia (Department of Microbiology) has identified the decisive role of fucosidases - enzymes present both in the human intestine and in the gut microbiota - in infection by rotavirus and norovirus.

Research examining ancient sewer drain sediment suggests the Roman soldiers garrisoned at the fort of Vindolanda suffered with intestinal worms and diarrhoea - despite their toilets, baths and drinking water system. These chronic infections likely weakened soldiers, reducing fitness for duty. Helminths alone can cause nausea, cramping and diarrhoea.

Posted on: 19 December 2025 The team has uncovered that the Irish Cervical Cancer Screening programme has prevented over 5500 cancers in Ireland, that would over wise have occurred in the lifetime of women screened. The outcomes figured by the team give a solid support for the clear efficacy of cervical cancer screening in Ireland and beyond.
