'Surrogate sires' could create specially bred livestock, say scientists
18minTrials on mice show how sterile animals can produce sperm deriving from elite breeders Scientists have used gene-editing to create pigs, goats and cattle that can serve as so-called "surrogate sires" – male animals providing sperm that carry the genetic traits of elite donor animals – in a bid to tackle global food insecurity. For thousands of years, farmers have selectively bred livestock to cha
Virtual reality trains public to reverse opioid overdoses
22minThe United States has seen a 200% increase in the rate of deaths by opioid overdose in the last 20 years. But many of these deaths were preventable.

Boron nitride nanofilms will replace antibiotics for protection against bacterial and fungal infections
9hNUST MISIS material scientists have presented antibacterial nano-coatings based on boron nitride, which are highly effective against microbial pathogens (up to 99.99%). They can become a safe alternative to the usual antibiotics in implantology since they do not have typical negative side effects. The results of the work are published in ACS Applied Materials & Interfaces.

When methane-eating microbes eat ammonia instead
9hAs a side effect of their metabolism, microorganisms living on methane can also convert ammonia. In the process, they produce nitric oxide (NO), a central molecule in the global nitrogen cycle. Scientists from the Max Planck Institute for Marine Microbiology, Bremen (DE), and Radboud University, Nijmegen (NL), have now discovered the enzyme that produces NO, closing an important gap in our underst
Pandemic freight emissions reached 2030 target in just months. How do we make the changes stick?
