Phys.org / Flipping the switch on sperm motility offers new hope for male infertility
Infertility affects about one in six couples, and male factors account for roughly half of all cases—often because sperm don't swim well. Researchers from the University of Osaka have uncovered a key component of the "switch" ...
Phys.org / New lab-grown human embryo model produces blood cells
University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production of blood stem cells. ...
Phys.org / When minds align: A neural basis for flocking
When animals move together in flocks, herds, or schools, neural dynamics in their brain become synchronized through shared ways of representing space, a new study by researchers from the University of Konstanz (Germany) suggests. ...
Phys.org / Nanomaterial-based wireless sensor can monitor pressure injuries and hygiene risks in real time
A research team has co-developed a nanomaterial-based 'wireless multi-sensing platform' for the early detection of pressure injuries, which have a high prevalence among individuals with limited mobility, including the elderly ...
Phys.org / How tips for biomolecular engineering can be found in early Earth
Scientists know some of the broad strokes for how life emerged from primordial Earth, but digging into the processes that allowed for the emergence of an oxygenated atmosphere, processes like photosynthesis, the development ...
Phys.org / Chemobiological platform enables renewable conversion of sugars into core aromatic hydrocarbons of petroleum
With growing concerns over fossil fuel depletion and the environmental impacts of petrochemical production, scientists are actively exploring renewable strategies to produce essential industrial chemicals.
Phys.org / Researchers identify factors that influenced the expansion of the Patagonian ice sheet
An international research team led by the University of Bremen has investigated what influenced the expansion of the Patagonian ice sheet during the last ice age. The scientists found evidence that the advances and retreats ...
Phys.org / New link between peroxide and sulfide metabolism discovered
Peroxidases are enzymes that break down hydrogen peroxide in organisms. Since their discovery in 1998, the electron source of "peroxiredoxin 6-type" peroxidases for this reaction remained unclear. The research group of Professor ...
Phys.org / Moderate warming may not doom humid subtropical forests' carbon storage
A new study has challenged the long-standing assumption that global warming will inevitably turn humid subtropical forests into carbon sources, revealing these ecosystems may instead continue accumulating soil carbon under ...
Phys.org / Nano bone material exhibits high elasticity and strength to accelerate surgery and healing
A research team from the Department of Orthopedics and Traumatology at the University of Hong Kong's LKS Faculty of Medicine (HKUMed) has successfully developed a novel elastic calcium phosphate material that mimics the structure ...
Phys.org / New 3D model reveals geophysical structures beneath Britain
Magnetotelluric (MT) data, which contain measurements of electric and magnetic field variations at Earth's surface, provide insights into the electrical resistivity of Earth's crust and upper mantle. Changes in resistivity, ...
Phys.org / Nanobody-guided approach enables efficient fluorescent labeling of endogenous proteins
A research team led by Prof. Xu Pingyong from the Institute of Biophysics of the Chinese Academy of Sciences has developed an innovative approach to visualize and rapidly screen small peptide knockins. The new approach, termed ...
