Columbia Engineering researchers have developed a new method for improving T cell manufacture by focusing on the materials involved in this process. Their study uses a polymer mesh to activate the T cells, a critical step for their production. This approach simplifies processing compared to systems in use today. In addition, making the fibers out of a mechanically soft material improved T cell growth, outperforming the current gold standard on several fronts. (Advanced Biosystems)

Since their discovery in the 1960s, scientists have sought to answer an important question: How massive can neutron stars actually become? By contrast to black holes, these stars cannot gain in mass arbitrarily; past a certain limit there is no physical force in nature that can counter their enormous gravitational force. For the first time, astrophysicists at Goethe University Frankfurt have succeeded in calculating a strict upper limit for the maximum mass of neutron stars.

Research recently published in The Journal of Physiology has found that elderly people walk at a slower speed and tire more quickly because of loss of strength and mass in leg muscles. Using computer simulations they found that these physiological changes explain the slower walking speed preferred by the elderly, and that a focus on building up these leg muscles may be the only effective way to improve elderly walking.

Strolling around or running to catch the train similarly requires us to move. However, the neuronal mechanisms in the brain that allow us to initiate and control these movements are different, a new study in the Journal Nature from University of Copenhagen and Karolinska Institutet reveals. 'Start neurons' in the midbrain are essential to take the first step to initiate locomotion and control the speed, mice models show.

Despite progress in recent decades, more than 10,000 alcohol-impaired driving fatalities occur each year in the US. To address this persistent problem, stakeholders -- from transportation systems to alcohol retailers to law enforcement -- should work together to implement policies and systems to eliminate these preventable deaths, says a new report from the National Academies of Sciences, Engineering, and Medicine.
