Zika virus uses cells’ ‘self-care’ system to turn against host
A new study reveals the biological secret to the Zika virus’s infectious success: Zika uses host cells’ own “self-care” system of clearing away useless molecules to suppress the host proteins that the virus has employed to get into those cells in the first place.
While these cell surface proteins are valuable for viral entry, they also have roles in producing an antiviral response. Before that can happen, the virus manipulates a process cells use to keep themselves healthy to lower the…

New study analyzes air quality impacts of wildfire smoke
With wildfires increasing in frequency, severity, and size in the Western U.S., researchers are determined to better understand how smoke impacts air quality, public health, and even the weather. As fires burn, they release enormous amounts of aerosols — the vaporized remains of burning trees and homes that enter the atmosphere and the air we breathe. Now, a new study dissects these aerosols and gases to pinpoint their potential effects on our health as well as the planet’s short and…

Mitochondrial DNA mutation accumulation may not be a determining factor in aging
Mutations accumulated in mitochondrial DNA associated with aging were earlier believed to cause aging by decreasing the energy-producing function (mitochondrial respiratory function). In this study, researchers at University of Tsukuba demonstrated that mitochondrial respiratory function is not reduced even when wild-type mice accumulated the same level of mutations as premature aging model mice, indicating the need to reinvestigate the conventional theory.
The human genome is broadly…

Study quantifies the sleep loss and disruption experienced by new mothers
A new study to be presented at the SLEEP 2025 annual meeting quantifies the amount of sleep loss experienced by first-time mothers in the weeks after giving birth and is the first to identify the unique type of sleep disruption that persists throughout the first months of motherhood.
Results show that the average daily sleep duration of new mothers was 4.4 hours during the first week after giving birth compared with a pre-pregnancy sleep duration of 7.8 hours. Their longest stretch of…

Location matters: Belly fat compared to overall body fat more strongly linked to psoriasis risk
Researchers have found that central body fat, especially around the abdomen, is more strongly linked to psoriasis risk than total body fat, particularly in women. This link between central fat and psoriasis remained consistent regardless of genetic predisposition, indicating that abdominal fat is an independent risk factor.The study in the Journal of Investigative Dermatology, published by Elsevier, provides insights that could help improve early risk prediction and guide personalized…

Wilms tumors: How genes and imprinting pave the way for cancer
A research team at the Biocenter of Julius-Maximilians-Universität Würzburg (JMU), together with cooperation partners at the Wellcome Sanger Institute in Cambridge (UK), has taken a significant step towards understanding Wilms’ tumors, malignant kidney tumors in young children. Using samples from the Wilms tumor biobank, the team was able to systematically decipher the hereditary predisposition for Wilms tumors in a large cohort. The results have now been published in the journal Genome…

Boys who are overweight in their early teens risk passing on harmful epigenetic traits to future children
A new study suggests that boys who become overweight in their early teens risk damaging the genes of their future children, increasing their chances of developing asthma, obesity and low lung function.
Research published in Communications Biology is the first human study to reveal the biological mechanism behind the impact of fathers’ early teenage obesity on their children.
Researchers from the University of Southampton and the University of Bergen in Norway investigated the epigenetic…

A chip with natural blood vessels
How can we investigate the effects of a new drug? How can we better understand the interaction between different organs to grasp the systemic response? In biomedical research, so-called organs-on-a-chip, also referred to as microphysiological systems, are becoming increasingly important: by cultivating tissue structures in precisely controlled microfluidic chips, it is possible to conduct research much more accurately than in experiments involving living humans or animals.
However, there has…

Chronic renal failure: Discovery of a crucial biomarker
In a world first, Canadian scientists at the CRCHUM, the hospital research centre affiliated with Université de Montréal, have identified microRNA able to protect small blood vessels and support kidney function after severe injury.
For the four million people diagnosed with chronic renal failure in Canada — and millions more abroad — this scientific advancement could have a major impact on early diagnosis and prevention of the disease.
Previously, there was no known reliable biomarker…
