Attacking tumors from the inside

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.

Comprehensive look at US fuel economy standards show big savings on fuel and emissions

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...

Autonomous robot plays with NanoLEGO

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.

When doing good boosts health, well-being

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.

Tiny biological package gets drug right to the 'heart' of transplant rejection

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.

Natural pest control saving billions

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.

Children can have COVID-19 antibodies and virus in their system simultaneously

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.
