LOUISVILLE, Ky. - A research team at the University of Louisville has discovered that an immune checkpoint molecule they developed for cancer immunotherapy, also protects against future development of multiple types of cancer when administered by itself.

UCLA researchers and collaborators at eight other research institutions have created an extremely light, very durable ceramic aerogel. The material could be used for applications like insulating spacecraft because it can withstand the intense heat and severe temperature changes that space missions endure.

PROVIDENCE, R.I. [Brown University] -- Using an army of small satellites, researchers have shown that water levels in small lakes across northern Canada and Alaska are far more variable during the summer than previously thought. The findings, published in Geophysical Research Letters, could have implications for how scientists calculate the natural greenhouse gas emissions from these northern lakes.

Like going from a pinhole camera to a Polaroid, a significant mathematical update to the formula for a popular bioinformatics data visualization method will allow researchers to develop snapshots of single-cell gene expression not only several times faster but also at much higher-resolution. Published in Nature Methods, this innovation by Yale mathematicians will reduce the rendering time of a million-point single-cell RNA-sequencing (scRNA-seq) data set from over three hours down to just fifteen minutes.

February 14, 2019 -- A new study on the measles epidemic in China has far-reaching implications for eliminating the infection globally, according to researchers at Columbia University Mailman School of Public Health. Using a new model-inference system developed at the Columbia Mailman School, the researchers were able to estimate population susceptibility and demographical characteristics in three key locations in China, in a period that spans the pre-vaccine and modern mass-vaccination eras. Until now, the dynamics of transmitting measles here had been largely unknown.

Potentially lethal heart conditions may become easier to spot and may lead to improvements in prevention and treatment thanks to innovative new software that measures electrical activity in the organ.

The heart's pumping ability is controlled by electrical activity that triggers the heart muscle cells to contract and relax. In certain heart diseases such as arrhythmia, the organ's electrical activity is affected.

Sierra Leone has one of the highest maternal mortality ratios in the world -- for every 100,000 live births, 1360 women will die. In Norway, that number is just 5 women per 100,000 live births; in the US, it's 14, according to the United Nations Population Fund.

Why are so many women dying in Sierra Leone? The answer is simple: childbirth can be complicated and there are simply not enough health care providers to address the needs of this small West African country of 7 million people.

ANN ARBOR--In a finding that runs counter to a common assumption in physics, researchers at the University of Michigan ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away.

The approach could lead to new solid-state cooling technology for future microprocessors, which will have so many transistors packed into a small space that current methods can't remove heat quickly enough.

Ten years into the future. That's about how far UC Santa Barbara electrical and computer engineering professor John Bowers and his research team are reaching with the recent development of their mode-locked quantum dot lasers on silicon. It's technology that not only can massively increase the data transmission capacity of data centers, telecommunications companies and network hardware products to come, but do so with high stability, low noise and the energy efficiency of silicon photonics.

For the first time ever, researchers are comprehensively sequencing the human immune system, which is billions of times larger than the human genome. In a new study published in Nature from the Human Vaccines Project, scientists have sequenced a key part of this vast and mysterious system -- the genes encoding the circulating B cell receptor repertoire.
