The chemotherapy drug called cyclophosphamide prevents graft-versus-host (GVHD) disease in people who receive bone marrow transplants. New experiments point to an immune system cell that evades the toxic effects of cyclophosphamide and protects patients from a lethal form of GVHD.

The findings could pave the way for improvements in preventing GVHD and rejection of transplanted bone marrow and new therapies to prevent or treat a relapse of the underlying cancer after a transplant.

Whistling kettles have been around for over a hundred years but science behind the mechanism of this siren sound, portent of delicious tea and cocoa (and heretical instant coffee) has never been fully described scientifically.

Ask an engineer or a physicist and you just get some hand-waving about the vibrations made by the build-up of steam escaping through two metal spout plates - everybody knows that, we whistle with our mouths too.

An automated system,  the Child Health Improvement through Computer Automation system (CHICA), helps pediatricians focus on the specific health needs of each patient in the short time allotted for preventive care and improves autism screening rates by identifying at-risk children at the 24-month visit., according to a new paper.

Nationwide children typically are not diagnosed with autism until age 4½ or 5 years. 
Approximately 1 in 88 children has been identified with an autism spectrum disorder, according to estimates from the CDC's Autism and Developmental Disabilities Monitoring Network. Once an autism diagnosis is made, it is easier for a family to obtain needed services, including early intervention to gain developmental skills.

Jupiter's Great Red Spot, a massive storm big enough to engulf the Earth two times over, is one of the solar system's most enigmatic landmarks and a mystery of fluid dynamics  – because it  should have disappeared centuries ago. 

Some new work will be presented by Pedram Hassanzadeh, a postdoctoral fellow at Harvard and Philip Marcus, a professor of fluid dynamics at Berkeley at the annual meeting of the American Physical Society's Division of Fluid Dynamics in Pittsburgh on November 25th. They think they can explain why Jupiter's Great Red Spot persists

"Based on current theories, the Great Red Spot should have disappeared after several decades. Instead, it has been there for hundreds of years," said Hassanzadeh. 

When the Supreme Court was debating the legal foundation of the Affordable Care Act in the United States, Justice Antonin Scalia challenged the Obama administration claim that the controversial individual mandate provision was Constitutionally legitimate, even under the broad 'Commerce' clause.

"Could you define the market -- everybody has to buy food sooner or later, so you define the market as food, therefore, everybody is in the market; therefore, you can make people buy broccoli," Scalia said.
