Surprising number of environmental pollutants in hedgehogs

Lead, pesticides, brominated flame retardants, plastic additives, polychlorinated biphenyls (PCBs), and heavy metals. This is what researchers at Lund University in Sweden found when they collected dead hedgehogs to investigate the environmental pollutants found in urban environments. Previous research has investigated the presence of heavy metals in hedgehogs from other urban areas in Europe and […]

How a critical enzyme keeps potentially dangerous genes in check

You may have heard of the fantastic-sounding “dark side of the genome.” This poorly studied fraction of DNA, known as heterochromatin, makes up around half of your genetic material, and scientists are now starting to unravel its role in your cells. For more than 50 years, scientists have puzzled over the genetic material contained in […]

Nature’s viny vampire: Discovering what drives parasitic Cuscuta campestris

The parasitic vine Cuscuta campestris grows by latching onto the stems and leaves of plants and inserting organs called haustorium into the host plant tissues to draw nutrients. The haustorium is formed when ion channels in the cell membrane are stimulated during coiling and induce a reaction within the cell. Further, Cuscuta campestris has many […]

Importin-9 and a TPR domain protein MpH drive periodic patterning of ciliary arrays in Tetrahymena

We explored how the number of structures is determined in an intracellular organelle series. In Tetrahymena, the oral apparatus contains three diagonal ciliary rows: M1, M2, and M3. During development, the M rows emerge by sequential segmentation of a group of basal bodies, starting with the longest and most anterior M1 and ending with the […]

Global patterns in seed plant distribution over millions of years

Why do some plants thrive in specific regions but not in others? A study led by researchers at the University of Göttingen explores the factors shaping plant distributions and how these patterns have changed over millions of years. Analyzing nearly 270,000 seed plant species worldwide, the research highlights the roles of environmental conditions and dispersal […]

Cartilage and bone development: Three paths to skeleton formation

In vertebrates, the skeleton of different regions of the body arises from different precursor cells. Researchers at the University of Basel have now discovered that these skeletal cells do not just differ in their developmental origin, but also in their gene regulation — which may be a key to the vertebrates’ evolutionary success story. From […]

We must not ignore eugenics in our genetics curriculum, says professor

To encourage scientists to speak up when people misuse science to serve political agendas, biology professor Mark Peifer of the University of North Carolina at Chapel Hill argues that eugenics should be included in college genetics curriculums. In an opinion paper publishing March 27 in the Cell Press journal Trends in Genetics, Peifer explains how […]

How elephants plan their journeys: New study reveals energy-saving strategies

A new study has revealed that African Elephants have an extraordinary ability to meet their colossal food requirements as efficiently as possible. Data from over 150 elephants demonstrated that these giants plan their journeys based on energy costs and resource availability. The findings – published today (26 March) in the Journal of Animal Ecology- could […]

Intersection of GPCR trafficking and cAMP signaling at endomembranes

GPCRs comprise the largest family of signaling receptors and control essentially every physiological process. Many biochemical reactions underlying GPCR signaling are now elucidated to atomic resolution in cell-free preparations, but how elemental signaling reactions are organized in intact cells remains less clear. Significant progress has been made toward bridging this knowledge gap by leveraging new […]

Healthy eating in midlife linked to overall healthy aging

Maintaining a healthy diet rich in plant-based foods, with low to moderate intake of healthy animal-based foods and lower intake of ultra-processed foods, was linked to a higher likelihood of healthy aging — defined as reaching age 70 free of major chronic diseases and with cognitive, physical, and mental health maintained, according to a new […]
