Report calls for more integration of physical, life sciences for needed advances in biomedical research.
What if lost limbs could be regrown? Cancers detected early with blood or urine tests, instead of invasive biopsies? Drugs delivered via nanoparticles to specific tissues or even cells, minimizing unwanted side effects? While such breakthroughs may sound futuristic, scientists are already exploring these and other promising techniques.
But the realization of these transformative advances is not guaranteed. The key to bringing them to fruition, a landmark new report argues, will be strategic and sustained support for “convergence”: the merging of approaches and insights from historically distinct disciplines such as engineering, physics, computer science, chemistry, mathematics, and the life sciences.
The report, “Convergence: The Future of Health,” was co-chaired by Tyler Jacks, the David H. Koch Professor of Biology and director of MIT’s Koch Institute for Integrative Cancer Research; Susan Hockfield, noted neuroscientist and president emerita of MIT; and Phillip Sharp, Institute Professor at MIT and Nobel laureate, and will be presented at the National Academies of Sciences, Engineering, and Medicine in Washington on June 24.
The report draws on insights from several dozen expert participants at two workshops, as well as input from scientists and researchers across academia, industry, and government. Their efforts have produced a wide range of recommendations for advancing convergence research, but the report emphasizes one critical barrier above all: the shortage of federal funding for convergence fields.
“Convergence science has advanced across many fronts, from nanotechnology to regenerative tissue,” says Sharp. “Although the promise has been recognized, the funding allocated for convergence research in biomedical science is small and needs to be expanded. In fact, there is no federal agency with the responsibility to fund convergence in biomedical research.”
Helping computers learn to tackle big-data problems outside their comfort zones
Imagine combing through thousands of mugshots desperately looking for a match. If time is of the essence, the faster you can do this, the better. A*STAR researchers have developed a framework that could help computers learn how to process and identify these images both faster and more accurately1.
Peng Xi of the A*STAR Institute for Infocomm Research notes that the framework can be used for numerous applications, including image segmentation, motion segmentation, data clustering, hybrid system identification and image representation.
A conventional way that computers process data is called representation learning. This involves identifying a feature that allows the program to quickly extract relevant information from the dataset and categorize it — a bit like a shortcut. Supervised and unsupervised learning are two of the main methods used in representation learning. Unlike supervised learning, which relies on costly labeling of data prior to processing, unsupervised learning involves grouping or ‘clustering’ data in a similar manner to our brains, explains Peng.
PolyU breaks the world record of fastest optical communications for data centres
The Hong Kong Polytechnic University (PolyU) has achieved the world’s fastest optical communications speed for data centres by reaching 240 G bit/s over 2km, 24 times of the existing speed available in the market. Compared to existing alternatives in the market, the technology developed by PolyU has reduced the cost of data transmission per unit to just one-fourth, and therefore is practical for commercialisation purposes. Speedy transmission at a significantly low cost for data centres enables end users to widely use new forms of communications such as immersive videos, augmented reality and virtual reality.
On a societal level, the increased transmission speed will open up a new era for Big Data and Internet of Things (IoT) applications, driving innovation and technology advancement.
With this breakthrough, around 10,000 persons can stream 4K video at the same time, compared to only 400 persons under the current available speed.
