Ninety-five per cent of world's fish hide in mesopelagic zone
An international team of marine biologists has found mesopelagic fish in the earth's oceans constitute 10 to 30 times more biomass than previously thought.
Classic microscopy reveals borrelia bacteria
A simple method has been found that tells people who have become seriously ill after a tick bite once and for all whether they have bacteria in their blood.
Nice organisms finish first: Why cooperators always win in the long run
Leading physicists last year turned game theory on its head by giving selfish players a sure bet to beat cooperative players. Now two evolutionary biologists at Michigan State University offer new evidence ...
Scientific study turns understanding about evolution on its head
(Phys.org) —Our understanding of how animals on the planet evolved may be wrong, according to scientists at the University.
Generosity leads to evolutionary success, biologists show
With new insights into the classical game theory match-up known as the "Prisoner's Dilemma," University of Pennsylvania biologists offer a mathematically based explanation for why cooperation and generosity have evolved in ...
Using analog computation circuits, engineers design cells that can compute logarithms, divide and take square roots
MIT engineers have transformed bacterial cells into living calculators that can compute logarithms, divide, and take square roots, using three or fewer genetic parts. Inspired by how analog electronic circuits ...
Scientists report breakthrough in DNA editing technology
Scientists at The Scripps Research Institute (TSRI) have found a way to apply a powerful new DNA-editing technology more broadly than ever before.
Mystery giant jellyfish washes up in Australia
Scientists were on Thursday working to classify a new species of giant jellyfish that washed up on an Australian beach, describing it as a "whopper" that took their breath away.
Inside the cell, an ocean of buffeting waves
Conventional wisdom holds that the cytoplasm of mammalian cells is a viscous fluid, with organelles and proteins suspended within it, jiggling against one another and drifting at random. However, a new biophysical ...
Biologists find 'missing link' in the production of protein factories in cells
Biologists at UC San Diego have found the "missing link" in the chemical system that enables animal cells to produce ribosomes—the thousands of protein "factories" contained within each cell that manufacture ...
Study shows how early Earth kept warm enough to support life
Solving the "faint young sun paradox"—explaining how early Earth was warm and habitable for life beginning more than 3 billion years ago even though the sun was 20 percent dimmer than today—may not be ...
Long-held assumption about emergence of new species questioned
Darwin referred to the origin of species as "that mystery of mysteries," and even today, more than 150 years later, evolutionary biologists cannot fully explain how new animals and plants arise.
Astrobiologists find Martian clay contains chemical implicated in the origin of life
(Phys.org) —Researchers from the University of Hawaii at Manoa NASA Astrobiology Institute (UHNAI) have discovered high concentrations of boron in a Martian meteorite. When present in its oxidized form ...
The Red Queen was right: We have to run to keep in place
Biologists quote Lewis Carroll when arguing that survival is a constant struggle to adapt and evolve. Is that true, or do groups die out because they experience a run of bad luck? Charles Marshall and Tiago ...
