How microbes generate and use their energy to grow
- ScienceDaily
- 19/8/23 20:07
Researchers have shed light on how bacteria and baker's yeast generate and use their energy to grow. Knowing about cells' energy use is essential for industrial biotech processes.
Successful egg harvest breaks new ground in saving the northern white rhinoceros
- ScienceDaily
- 19/8/23 20:07
There are only two northern white rhinos left worldwide, both of them female. Saving this representative of megafauna from extinction seems impossible under these circumstances, yet an international consortium of scientists and conservationists just completed a procedure that could enable assisted reproduction techniques to do just that.
How gonorrhea develops resistance to antibiotics
- ScienceDaily
- 19/8/23 20:07
As public health officials worry about the emergence of antibiotic-resistant gonorrhea, researchers are tracing how antibiotics bind to a gonococcal protein, information that can help lead to new antimicrobials.

- ScienceDaily
- 19/8/23 20:06
Researchers have deciphered new mechanisms that enable the regeneration of nerve fibers. This could open up new treatment approaches for the brain, optic nerve, and spinal cord injuries.
Bioprinting complex living tissue in just a few seconds
- ScienceDaily
- 19/8/23 15:48
Researchers have developed an extremely fast optical method for sculpting complex shapes in stem-cell-laden hydrogels and then vascularizing the resulting tissue. Their groundbreaking technique stands to change the field of tissue engineering.
Study models new method to accelerate nanoparticles
- ScienceDaily
- 19/8/23 15:48
Researchers have modeled a method to manipulate nanoparticles as an alternative mode of propulsion for tiny spacecraft that require very small levels of thrust. The team simulated a system that uses light to generate an electromagnetic field to move the particles from a reservoir, funneled through an injector, then shot out of an accelerator to produce thrust.

Frying oil consumption worsened colon cancer and colitis in mice, study shows
- ScienceDaily
- 19/8/23 15:48
Food scientists have shown that feeding frying oil to mice exaggerated colonic inflammation, enhanced tumor growth and worsened gut leakage, spreading bacteria or toxic bacterial products into the bloodstream.
A new method for quantifying crystal semiconductor efficiency
- ScienceDaily
- 19/8/23 15:48
Scientists have found a new way to successfully detect the efficiency of crystal semiconductors.
Researchers find a way to stop lung damage due to the body's immune response
- ScienceDaily
- 19/8/23 15:17
Researchers have discovered a new way to stop harmful inflammation in the lungs due to sepsis and injury. They found a molecule, present during inflammation that binds to white blood cells allowing them to pass from the blood stream into the tissue and cause severe damage.

Addressing causes of mortality in Zambia
- ScienceDaily
- 19/8/23 15:17
Despite the fact that people in sub-Saharan Africa are now living longer than they did two decades ago, their average life expectancy remains below that of the rest of the world population. A new study looked into the importance of various causes of death in Zambia and how eliminating the most prominent of these would impact life expectancy in the country.
