Scientists identify gene family key to unlocking vertebrate evolution

1 day ago from Science Daily

New research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an...

Endangered wildlife, habitat burned in Washington's wildfires

1 day ago from Physorg

Entire wildlife areas have been destroyed and endangered populations of animals gravely depleted by wildfires burning in Eastern Washington.

Coconut rhinoceros beetle makes unexpected 'host shift' to Guam's cycad trees

1 day ago from Science Daily

Researchers have documented what biologists call a 'host shift' of the coconut rhinoceros beetle in Guam. The beetle, first documented as an invasive species in Guam in 2007, has been...

Building bridges: PARP enzymes bring broken DNA together

1 day ago from Science Daily

Researchers capture the structure of PARP enzymes at work, leading to a new understanding of DNA repair that may aid cancer treatments targeting the process.

Marine animals live where ocean is most breathable, ranges may shrink with climate change

1 day ago from Science Daily

New research shows that a wide variety of marine animals -- from vertebrates to crustaceans to mollusks -- already inhabit the maximum range of breathable ocean that their physiology will...

Real Neurons are Noisy. Can Neural Implants Figure That Out?

1 day ago from Science Blog

 If human eyes came in a package, it would have to be labeled “Natural product. Some variation may occur.” Because the million-plus retinal ganglion cells that send signals to the...

Scientists explain how diverse species coexist in microbial communities

1 day ago from Physorg

Diversity in many biological communities is a sign of an ecosystem in balance. When one species dominates, the entire system can go haywire. For example, the uncontrolled overgrowth of certain...

Next-gen organoids grow and function like real tissues

1 day ago from Science Daily

Bioengineers have created miniature intestines in a dish that match up anatomically and functionally to the real thing better than any other lab-grown tissue models. The biological complexity and longevity...

Mapping cavefish brains leads to neural origin of behavioral evolution

1 day ago from Physorg

For more than 1 million years, independent cavefish populations that are geographically and hydrologically isolated from one another have evolved to include about 29 different populations. Among them, the tiny...

Native stinging tree toxins match the pain of spiders and scorpions

1 day ago from Physorg

The painful toxins wielded by a giant Australian stinging tree are surprisingly similar to the venom found in spiders and cone snails, University of Queensland researchers have found.

Minnesota moose will not be listed as federally endangered species

1 day ago from Physorg

Minnesota and Midwestern moose will not be listed as a federally endangered species, putting to bed a petition that's been under review for five years.

Scientists update genome editing technology

1 day ago from Physorg

Researchers from Peter the Great St. Petersburg Polytechnic University (SPbPU) in collaboration with colleagues from the Pavlov University, ITMO University, and the University of Hamburg compared their developed carriers for...

Scientists identify gene family key to unlocking vertebrate evolution

New University of Colorado Boulder-led research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million...

COVID-19 virus uses heparan sulfate to get inside cells

1 day ago from Science Daily

Researchers discovered that the SARS-CoV-2 virus can't grab hold of cell receptor ACE2 without a carbohydrate called heparan sulfate, which is also found on lung cell surfaces -- disrupting that...

Replicating a genome starts with a twist, a pinch, and a bit of a dance

1 day ago from Physorg

The most basic activity of a living thing is to turn one copy of its genome into two copies, crafting one cell into two. That replication event begins with a...

Sharp attention explains why the early bird gets the worm

1 day ago from Physorg

Many of the characteristics related to auditory attention in birds match those of humans, according to a study from the University at Buffalo.

Research opens the way to new drugs

1 day ago from Physorg

Research by a team at Te Herenga Waka–Victoria University of Wellington's School of Biological Sciences dispels the belief that on the assembly line of enzymes there is a "proof-reading" mechanism...

Migration shapes patterns of disease transmission

1 day ago from Physorg

Long-distance animal migrations can trigger relapse of dormant infections, influencing when and where infection risk peaks, according to a new paper in Proceedings of the Royal Society B. The findings...

Coconut rhinoceros beetle makes unexpected 'host shift' to Guam's cycad trees
