Monash University researchers have validated a way to successfully detect a diverse range of bacteria (pathogens) that cause diarrhoeal disease in informal settlements.

Better protection from disease for people living in communities facing water, sanitation and hygiene challenges is essential, as microbes that cause gastrointestinal disease (enteropathogens) are responsible for 1.4 million deaths per year, predominantly in children under five, and cause impaired nutrition and development.

New Brunswick, N.J. (May 12, 2021) - A Rutgers study finds that symbiotic bacteria that colonize root cells may be managed to produce hardier crops that need less fertilizer.

The study appears in the journal Microorganisms.

Bacteria stimulate root hair growth in all plants that form root hairs, so the researchers examined the chemical interactions between bacteria inside root cells and the root cell.

Modern vaccines such as those against Sars-CoV-2 use tiny lipid spheres to transport genetic information into cells and let the body build up an immune defense against the virus. A team of scientists from Erlangen, Dresden, and London has now developed a completely new method to very efficiently deliver not only genes but also drugs and other substances into cells.

CHICAGO --- A new Northwestern Medicine study of placentas from patients who received the COVID-19 vaccine during pregnancy found no evidence of injury, adding to the growing literature that COVID-19 vaccines are safe in pregnancy.

One of the most prominent evils of rapid industrialization has been the emission of toxic pollutants into the surrounding biosphere, with often disastrous consequences for human beings. Several industrial processes, such as chemical manufacturing and printing, along with facilities such as power plants emit volatile organic compounds (VOCs) that are known to be cancer-causing and raise an important environmental issue in need of a solution.

Australian photovoltaics researchers have made a 'cool' discovery: Singlet fission and tandem solar cells - two innovative ways to generate solar power more efficiently - also help to lower operating temperatures and keep devices running for longer.

Tandem cells can be made from a combination of silicon - the most commonly used photovoltaics material - and new compounds like perovskite nanocrystals, which can have a larger bandgap than silicon and help the device to capture more of the solar spectrum for energy generation.

ORLANDO, May 10, 2021 -University of Central Florida researchers are building on their technology that could pave the way for hypersonic flight, such as travel from New York to Los Angeles in under 30 minutes.

In their latest research published in the journal Proceedings of the National Academy of Sciences, the researchers discovered a way to stabilize the detonation needed for hypersonic propulsion by creating a special hypersonic reaction chamber for jet engines.

Hamilton, ON (May 10, 2021) - It is well known that each person's gut bacteria is vital for digestion and overall health, but when does that gut microbiome start?

New research led by scientists from McMaster University and Charité - Universitätsmedizin Berlin in Germany has found it happens during and after birth, and not before.

McMaster researchers Deborah Sloboda and Katherine Kennedy examined prenatal stool (meconium) samples collected from 20 babies during breech Cesarean delivery.

ATLANTA--Gestures--such as pointing or waving--go hand in hand with a child's first words, and twins lag behind single children in producing and using those gestures, two studies from Georgia State University psychology researchers show.

Twins produce fewer gestures and gesture to fewer objects than other children, said principal researcher Seyda Ozcaliskan, an associate professor in the Department of Psychology. Language use also lags for twins, and language--but not gesture--is also affected by sex, with girls performing better than boys, Ozcaliskan said.

The use of multimode optical fibers to boost the information capacity of the Internet is severely hampered by distortions that occur during the transmission of images because of a phenomenon called modal crosstalk.

DALLAS, May 10, 2021 — Managing weight, blood pressure and cholesterol in children may help protect brain function in later life, according to new research published today in the American Hear

Researchers have successfully developed a new Strep A human challenge model, paving the way to test vaccines against the common deadly bacteria that causes sore throats, scarlet fever and skin sores.

The collaborative research effort, led by the Murdoch Children's Research Institute (MCRI) and published in The Lancet Microbe, found the model, which deliberately infected healthy adult volunteers with the bacteria in a controlled environment, was safe and would now be used to trial Strep A candidate vaccines.

The two meters of -stretched- DNA contained in human cells are continuously twisting and untwisting to give access to genetic information: when a gene is expressed to generate a protein, the two strands of DNA are separated to give access to all the machinery necessary for this expression, resulting in an excessive accumulation of coiling that needs to be resolved later.

The air in the United States and Western Europe is much cleaner than even a decade ago. Low-sulfur gasoline standards and regulations on power plants have successfully cut sulfate concentrations in the air, reducing the fine particulate matter that harms human health and cleaning up the environmental hazard of acid rain.

Nanofabrication of electronic devices has reached a single nanometer scale (10-9 m). The rapid advancement of nanoscience and nanotechnology now requires atomic-scale optical spectroscopy in order to characterize atomistic structures that will affect the properties and functions of the electronic devices.
