Researchers have found that mothers of preterm babies have highly individual breast milk microbiomes, and that even short courses of antibiotics have prolonged effects on the diversity and abundance of microbes in their milk.
A new technology that allows researchers to peer inside malignant tumors shows that two experimental drugs can normalize aberrant blood vessels, oxygenation, and other aspects of the tumor microenvironment in non-small cell lung cancer (NSCLC), helping to suppress the tumor's growth and spread, researchers report.
The U.S. Army partnered with the University of Pittsburg Medical Center to create a biocontainment unit that could help healthcare workers caring for COVID-19 patients.
A researcher developed a mathematical method that shows climate change likely caused the rise and fall of an ancient civilization. A new article outlines the technique he developed and shows how shifting monsoon patterns led to the demise of the Indus Valley Civilization, a Bronze Age civilization contemporary to Mesopotamia and ancient Egypt.
Obesity may cause a hyperactive immune system response to COVID-19 infection that makes it difficult to fight off the virus, according to a new paper.
A new study finds that over their 40-year history, fuel economy standards in the United States have helped reduce reliance on foreign oil producers, saved $5 trillion in fuel costs and prevented 14 billion metric tons of carbon from being released into the atmosphere. The standards (known as CAFE standards), first enacted to reduce foreign oil dependence, were cost-effective, fair, durable and...
A new article highlights Operation Outbreak, an educational platform and simulation intended to teach high school and college students the fundamentals of responses to pandemics.
Atoms and molecules behave in a completely different way to macroscopic objects and each brick requires its own 'instruction manual'. Scientists have now developed an artificial intelligence system that autonomously learns how to grip and move individual molecules using a scanning tunneling microscope.
An infection with the coronavirus SARS-CoV-2 can affect multiple organs. Researchers have investigated cellular factors that could be significant for an infection. They analyzed the activity of 28 specific genes in a wide range of human tissues.
A new species of freshwater Crustacea has been discovered during an expedition of the desert Lut, known as the hottest place on Earth.
A new study has revealed the size of the legendary giant shark Megalodon, including fins that are as large as an adult human.
A new technology that uses a protein's structure to predict the inner wiring that controls the protein's function and dynamics is now available for scientists to utilize. The tool may be useful for protein engineering and drug design.
Performing acts of kindness and helping other people can be good for people's health and well-being, according to new research. But not all good-hearted behavior is equally beneficial to the giver. The strength of the link depends on many factors, including the type of kindness, the definition of well-being, and the giver's age, gender and other demographic factors.
For patients who receive a heart transplant in the near future, the old adage, 'Good things come in small packages,' may become words to live by. Researchers have demonstrated in mice that they can easily deliver a promising anti-rejection drug directly to the area surrounding a grafted heart by packaging it within a tiny three-dimensional, protein gel cocoon known as a hydrogel.
Dye-sensitised solar cells could perform better thanks to improved understanding of additives in optimizing electrolytes. Researchers have determined that the molecules 4-tert-butylpyridine (tBP) and 1-methyl-benzimidazole (NMBI) can play an integral role in suppressing recombination losses and maximizing efficiency.
Biological control of insect pests - where 'natural enemies' keep pests at bay - is saving farmers in Asia and the Pacific billions of dollars, according to new research. Biological control involved the careful release of an exotic natural enemy from a pest's native habitat.
With many questions remaining around how children spread COVID-19, researchers set out to improve the understanding of how long it takes pediatric patients with the virus to clear it from their systems, and at what point they start to make antibodies that work against the coronavirus. The study finds that the virus and antibodies can coexist in young patients.
New research shows U.S. adults who experience common symptoms of anxiety and depression are at greater risk of delaying medical care and not receiving non-COVID-19 medical care amidst the pandemic.
About 6 million people in the United States are affected by chronic wounds. Now, a team of innovators has developed a wearable solution that allows a patient to receive treatment without leaving home.
Cat owners fall into five categories in terms of their attitudes to their pets' roaming and hunting, according to a new study.
People who've had COVID-19 should be swab tested again four or more weeks after symptoms first appear to minimize the risk of onward infection, suggests a large population-based study in one of Italy's former coronavirus hotspots.
Workers who have been exposed to sexual harassment in their workplace are at greater risk of suicide and attempting suicide, a new study finds.
Women who use permanent hair dye products to colour their hair at home do not experience greater risk of most cancers or greater cancer related mortality.
A lopsided merger of two black holes may have an oddball origin story, according to a new study.
