Miniature flying robots automatically inspect, analyze, and assess damage to infrastructure

Northeastern’s Jerome Hajjar and col­leagues are devel­oping a sophis­ti­cated system that uses autonomous small flying robots cou­pled with 3-​​D imaging and state-​​of-​​the art plan­ning, mod­eling, and analysis to inspect struc­tures from bridges to build­ings and auto­mat­i­cally iden­tify prob­lems, track their progress, and assess the need for follow-​​up.

Researchers challenge federal law in attempt to prevent ‘Big Data’ discrimination

Northeastern’s Alan Mis­love and Christo Wilson have been researching whether the algo­rithms e-​​commerce and other web­sites use to ana­lyze user pro­file data, web-​​browsing choices, and other online infor­ma­tion may lead to dis­crim­i­na­tion. Now the ACLU has sued the gov­ern­ment on their and others’ behalf so they can con­tinue to do so without prosecution.

Graduate’s engineering work featured on Shark Week

Carl Fiester helped design a state-​​of-​​the-​​art autonomous under­water vehicle that last year cap­tured unique footage of great white sharks’ behavior off the coast of Mexico. Ear­lier this week, the footage was fea­tured on a Shark Week show on the Dis­covery Channel.

Comfort dogs bring healing in times of tragedy

Twelve golden retrievers recently arrived in Orlando to bring com­fort to the sur­vivors and those grieving after the mass shooting at the gay night­club Pulse. Here, Northeastern’s Lisa Feldman Bar­rett, who spe­cial­izes in the psy­chology of emo­tion, explains how dogs help bring our ner­vous sys­tems back into bal­ance and, at least tem­porarily, make us feel safe.

Northeastern researchers find T-Mobile’s Binge On doesn’t live up to the hype

New research led by David Choffnes shows that what T-​​Mobile promises about free video streaming with Binge On is not what you, or con­tent providers, may actu­ally get. In many cases, sub­scribers were left with lower quality videos and unex­pected charges. More­over, because of flaws in T-Mobile’s system, the researchers found a way to make prac­ti­cally any Internet traffic free to subscribers.

Child’s play: Using virtual reality to advance physical therapy

Boston middle school stu­dents vis­ited campus last week to try out some new vir­tual reality games being designed for phys­ical therapy patients. Their game-​​playing will help researchers refine patient treat­ment and advance inter­dis­ci­pli­nary research.

World’s wind engineering experts convene at Northeastern

Northeastern’s Luca Caracoglia develops numer­ical method­olo­gies to sim­u­late how tall build­ings will respond to high winds, including hur­ri­canes. Last week he brought his exper­tise to bear as chairman and co-​​host of an inter­na­tional col­lo­quium. More than 200 engi­neering experts from around the world con­vened at North­eastern to dis­cuss how to best ana­lyze and con­struct tall build­ings, bridges, and other non-​​streamlined bodies.

Researchers reveal the hidden environmental and public health impacts of the US healthcare sector

Over the past 10 years, the U.S. health­care sector’s green­house gas emis­sions grew by more than 30 per­cent, accounting for 9.8 per­cent of the national total in 2013. “If the U.S. health­care sector were itself a country, it would rank 13th in the world for green­house gas emis­sions, ahead of the entire U.K.,” states a new paper coau­thored by North­eastern researcher Matthew Eckelman.

The ecstasy of working underwater

Think your work envi­ron­ment is hectic? Imagine trying to com­plete a task with an air tank strapped to your back as you get tossed around by ocean swells. Working under­water can be daunting, but these three divers wouldn’t trade it for anything.

Marine Science Center works to protect oceans’ ‘vital role in sustaining life on Earth’

In honor of World Oceans Day, we spoke with Marine Sci­ence Center director Geoff Trussell about ocean con­ser­va­tion and what the MSC is doing to help pro­tect our marine ecosystem.

Three ways the Northeastern community is addressing ocean plastics pollution

A big emphasis of World Oceans Day this year is bringing aware­ness to the problem of marine plastic pol­lu­tion. Mem­bers of the North­eastern com­mu­nity are already focused on this chal­lenge by building sus­tain­able skate­boards, visu­al­izing ocean plas­tics data, and building sen­sors to iden­tify microplas­tics in the sea.
