Phys.org / Maybe that's not liquid water on Mars after all

Ancient Mars boasted abundant water, but the cold and dry conditions of today make liquid water on the Red Planet seem far less probable. However, the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) detected ...

Phys.org / Biodegradable mulching film can protect plants without pesticides or plastics

Whether you're a home gardener or an industrial farmer, you might be familiar with mulching films—plastic sheets laid over the soil to protect seedlings and promote crop growth. But like many other plastic materials, these ...

Phys.org / Atoms passing through walls: Quantum tunneling of hydrogen within palladium crystal

At low temperatures, hydrogen atoms move less like particles and more like waves. This characteristic enables quantum tunneling, the passage of an atom through a barrier with a higher potential energy than the energy of the ...

Phys.org / Unlocking the genome's hidden half with new DNA sequencing technology

Cornell researchers have found that a new DNA sequencing technology can be used to study how transposons move within and bind to the genome. Transposons play critical roles in immune response, neurological function and genetic ...

Phys.org / Laser-induced break-up of C₆₀ fullerenes caught in real-time on X-ray camera

The understanding of complex many-body dynamics in laser-driven polyatomic molecules is crucial for any attempt to steer chemical reactions by means of intense light fields. Ultrashort and intense X-ray pulses from accelerator-based ...

Phys.org / Mercury pollution in marine mammals is increasing, new study finds

In 2017, a new global treaty was meant to bring mercury pollution under control. But three decades of data from UK harbor porpoises show mercury is still increasing, and is linked to a higher risk of dying from infectious ...

Phys.org / Plant breeding discovery could pave way for new crop species

One of the great mysteries in plant biology is how, given the clouds of pollen released by dozens of plant species all at the same time, an individual plant can recognize which particular species' pollen grains will induce ...

Phys.org / An electric discovery: Pigeons detect magnetic fields through their inner ear

In 1882, the French Naturalist Camille Viguier was among the first to propose the existence of a magnetic sense. His speculation proved correct. Many animals—from bats, to migratory birds and sea turtles use the Earth's ...

Phys.org / Understanding intrinsically disordered protein regions and their roles in cancer

Every function in a cell is associated with a particular protein or group of proteins, typically in a well-defined three-dimensional structure. However, intrinsically disordered regions of proteins defy this structure-function ...
