Phys.org / Nitrogen fixation 'off switch' discovery could one day help crops make their own fertilizer

Nitrogen is essential for life. It's needed to build proteins, DNA and many other components of cells. Although nitrogen gas makes up almost 80% of Earth's atmosphere, most organisms cannot use it directly. Certain microbes ...

Phys.org / Layered semiconductor unlocks magnetic control of light emitted by quantum condensates

Quantum technologies are considered key technologies of the future. However, research in this field requires not only scientific expertise but sometimes also highly specialized laboratory conditions. Bose–Einstein condensates ...

Phys.org / Cows deliver healthy calves without embryonic protein long thought essential for pregnancy

For decades, scientists have believed that a protein called interferon tau (IFNT) is indispensable for pregnancy in cattle. Produced by the early embryo, it was thought to signal its presence to the mother and prevent the ...

Phys.org / New 'computational microscope' simulates DNA packaging at more than ten times previous scale

The DNA in our cells wraps around proteins called histones to form nucleosomes, which organize into chromatin. This organization helps pack genetic material into the nucleus and influences how easily genes can be read and ...

Phys.org / Tracking down cellular gene functions with AI and microscopy

A new technology promises to enable more comprehensive investigations into how individual genes determine the appearance and behavior of cells. Researchers led by professor Veit Hornung at LMU's Gene Center and professor ...

Phys.org / Mapping how a single cell becomes an entire mouse

Growing inside each of us is a cellular family tree. Every one of the 37 trillion cells in our body is generated from another cell, going all the way back to a single fertilized egg. Much like we can draw a family tree tracking ...

Phys.org / Could grass become the clothes of the future?

Producing textile fibers from wood involves extracting cellulose from a structure that is tougher and more resistant than that of grass. But what if grass offered an easier—and potentially more environmentally friendly—alternative? ...

Phys.org / Lensless imaging method enables long-term monitoring of living cells without staining

In a study led by Tampere University, researchers have developed a new lensless imaging method that produces precise quantitative data on living cells from a single image. The compact system can be placed inside a standard ...

Phys.org / Light-driven method puts notoriously reactive hydrogen atoms to work for chemical synthesis

Hydrogen is the simplest element in the periodic table, consisting of just one proton and one electron. In chemistry, however, the smallest of atoms is anything but simple. First produced by Nobel laureate Irving Langmuir ...

Phys.org / 3D-printed inserts bring single-objective light sheet microscopy to commercial sample chambers

Light sheet microscopy allows biologists to selectively light up a thin slice of a sample. This method can improve image contrast by reducing background light while remaining gentle on the sample, reducing photodamage and ...

Phys.org / A trick from tardigrades could help human blood withstand freezing

Tardigrades survive conditions that would destroy most other living things: freezing, dehydration and the vacuum of space. Researchers even put tiny tattoos on them, and the animals don't seem to mind. By learning how these ...

Phys.org / Atlantic weather pattern shaped southern Greenland's rain and snow for millennia, sediments reveal

In high-latitude coastal areas, Arctic amplification means that temperatures are rising faster than the global average. This combination of rising temperatures and changing precipitation patterns driven by the North Atlantic ...
