Antibiotic resistance surges in dolphins, mirroring humans

Antibiotic resistance is one of the biggest public health challenges in the world today since many common bacterial infections are developing resistance to the drugs once used to treat them, and new antibiotics aren't being ...

Microbes make chemicals for scent marking in a cat

Domestic cats, like many other mammals, use smelly secretions from anal sacs to mark territory and communicate with other animals. A new study from the Genome Center at the University of California, Davis shows that many ...

Scientists sharpen gene editing tool

Wake Forest Institute for Regenerative Medicine scientists have fine-tuned their delivery system to deliver a DNA editing tool to alter DNA sequences and modify gene function. The improved "hit and run" system works faster ...

'Yank': A new term in biophysics

Biologists and biomedical engineers are proposing to define the term "yank" for changes in force over time, something that our muscles and nerves can feel and respond to.

16 things you probably didn't know about cephalopod sex

If you've ever seen the Monterey Bay Aquarium's "Tentacles" exhibit, you know that cephalopods (squids, octopuses, and their kin) are awesome creatures. They can change the texture and color of their skin in the blink of ...

How new loops in DNA packaging help us make diverse antibodies

Diversity is good, especially when it comes to antibodies. It's long been known that a gene assembly process called V(D)J recombination allows our immune system to mix and match bits of genetic code, generating new antibodies ...

Multidrug resistance: Not as recent as we thought

Researchers from Osaka University have made the striking discovery that multidrug-resistant bacteria may have been around longer than we thought. In findings published this month in Communications Biology, the researchers ...

Method to customize microbes for better biofuel production

Scientists at the US Department of Energy's Oak Ridge National Laboratory have demonstrated a method to insert genes into a variety of microorganisms that previously would not accept foreign DNA, with the goal of creating ...

Extinction of Icelandic walrus coincides with Norse settlement

An international collaboration of scientists in Iceland, Denmark and the Netherlands has for the first time used ancient DNA analyses and C14-dating to demonstrate the past existence of a unique population of Icelandic walrus ...

Male Trinidad guppies find food thanks to females

For male Trinidad Guppies applies: if you are hungry, seek female company. A recent study led by scientists of the the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) and the Leibniz Institute for Zoo and ...

Mother cells as organelle donors

Microbiologists at LMU and UoG have discovered a recycling process in the eukaryotic parasite Toxoplasma gondii that plays a vital role in the organism's unusual mode of reproduction.

A new methodology for sequencing viruses

NUS scientists have developed a more efficient method to sequence the complete genomes of infectious diseases carried by mosquitoes directly from patient samples.

Decoding messages in the body's microscopic metropolises

A study aimed at identifying and examining the small messenger proteins used by microbes living on and inside humans has revealed an astounding diversity of more than 4,000 families of molecules – many of which have never ...
