Drug discovery could accelerate hugely with machine learning

Drug discovery could be significantly accelerated thanks to a new high precision machine-learning model, developed by an international collaboration of researchers, including the University of Warwick. The algorithm – partly devised by Dr James Kermode from Warwick’s School of Engineering – can accurately predict the interactions between a protein and a drug molecule based on a handful of reference experiments or simulations. Using just a few training references, it can predict whether or not a candidate drug molecule will…

2017 Year in review: Software across the stack | Engineering Blog | Facebook Code

This week we’re publishing a series of posts looking back at the technologies and advancements Facebook engineers introduced in 2017. Read our previous posts from this week about data centers, connectivity, and building immersive experiences. Facebook engineers write, edit, test, and ship thousands of code changes every day. In 2017, we made several optimizations across this workflow that have helped minimize the amount of time engineers spent waiting on machines, even as the number of engineers and amount of code…

Drones, volcanoes and the ‘computerisation’ of the Earth

The Mount Agung volcano spews smoke, as seen from Karangasem, Bali. Credit: EPA-EFE/MADE NAGI The eruption of the Agung volcano in Bali, Indonesia has been devastating, particularly for the 55,000 local people who have had to leave their homes and move into shelters. It has also played havoc with the flights in and out of the island, leaving people stranded while the experts try to work out what the volcano will do next. But this has been a fascinating time…

Navigating the Engineering Interview Process at Uber & Beyond

As one of the world’s fastest growing companies, Uber is always looking for new engineers to help us make transportation safer and more reliable. To accomplish this, we are developing technologies—from machine learning algorithms and data visualization platforms, to mobile frameworks and self-driving vehicles—at an unprecedented scale. Up for the challenge? If so, your first step (after applying, of course) is to meet with our team and interview to determine if Uber is the right fit for you! Read on…

Volumetric 3-D printing builds on need for speed

Volumetric 3D printing creates parts by overlapping three laser beams that define an object’s geometry from three different directions, creating a hologram-like 3D image suspended in the vat of resin. The laser light, which is at a higher intensity where the beams intersect, is kept on for about 10 seconds, enough time to cure the object. Credit: Lawrence Livermore National Laboratory While additive manufacturing (AM), commonly known as 3-D printing, is enabling engineers and scientists to build parts in configurations…

Scientists channel graphene to understand filtration, ion transport into cells — ScienceDaily

Tiny pores at a cell’s entryway act as miniature bouncers, letting in some electrically charged atoms — ions — but blocking others. Operating as exquisitely sensitive filters, these “ion channels” play a critical role in biological functions such as muscle contraction and the firing of brain cells. To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules, particularly water, that have an affinity for the charged…

Research team develops novel program to make more cost effective runways

Credit: Texas A&M University An aircraft’s impact on the runway is likely the last thing to cross anyone’s mind when boarding a flight. The constant taking off and landing of aircraft throughout the day places stress on runway pavement, which needs to be in good condition to ensure the safety of the aircraft and its passengers. Thanks to a predictive model developed by a collaborative research team led by the Zachry Department of Civil Engineering at Texas A&M, understanding how…

The Glimmer Binary Experience | LinkedIn Engineering

Co-authors: Sarah Clatterbuck, Chad Hietala, and Tom Dale A bit over a year ago, Ember.js got a major overhaul. In a tight collaboration between LinkedIn engineers and the open source community, we replaced Ember’s rendering engine with a new library, Glimmer VM, that improved performance and significantly reduced the size of compiled templates. Glimmer treats Handlebars templates as a functional programming language and compiles them into a sequence of instructions that can be executed in the browser. These instructions, or…

In collaboration with a leading telecommunications company, M1 Ltd,…

Researchers 3-D print lifelike artificial organ models

Researchers can attach sensors to the organ models to give surgeons real-time feedback on how much force they can use during surgery without damaging the tissue. Credit: McAlpine Research Group A team of researchers led by the University of Minnesota has 3D printed lifelike artificial organ models that mimic the exact anatomical structure, mechanical properties, and look and feel of real organs. These patient-specific organ models, which include integrated soft sensors, can be used for practice surgeries to improve surgical…
