Researchers find the tipping point between resilience and collapse in complex systems

Using sta­tis­tical physics, net­work sci­en­tist Albert-​​László Barabási and his col­leagues have devel­oped the first-​​ever tool to iden­tify whether systems—be they tech­no­log­ical, eco­log­ical, or biological—are in danger of failing.

3Qs: Detection of gravitational waves ‘opens a new window to the study of the universe’

On Thursday, a team of sci­en­tists announced that they had detected grav­i­ta­tional waves, rip­ples of energy across space-​​time sparked by the merging of two black holes. North­eastern physi­cist Pran Nath dis­cusses the impact of the major break­through. Image by NASA

Physicist uses light to accelerate treatment of drug-​​resistant cancers

Assis­tant pro­fessor Bryan Spring develops pho­to­dy­namic ther­a­pies that both target malig­nant cells and halt new tumor growth. It’s a novel one-​​two punch approach to per­son­al­ized medicine.

Facebook’s new degrees of separation: Does it matter?

Last week the pop­ular social media plat­form reported that each of us is con­nected to everyone else not by six but just three and a half other people. North­eastern net­work the­o­rist Albert-​​László Barabási offers a more com­pre­hen­sive view: the number itself is a “toss up,” depending on the den­sity of the network.

Researchers’ preclinical trial upends conventional wisdom about responses to fear

North­eastern assis­tant pro­fessor of psy­chology Rebecca Shansky pro­vides insights into new treat­ments for post-​​traumatic stress dis­order with a pre­clin­ical study that dis­tin­guishes how males and females respond to trau­matic events.

A climate change agreement was reached. Now what?

The two-​​week U.N. Frame­work Con­ven­tion on Cli­mate Change ended in Paris on Sat­urday with nearly 200 nations agreeing on a plan to combat cli­mate change. Here, North­eastern pro­fes­sors dis­cuss the good, the remaining chal­lenges, and the future of this his­toric accord.

The growth of physics research, and its changing impact on our lives

Over the past cen­tury, the dis­ci­pline of physics has expanded expo­nen­tially, crossing bound­aries into areas as diverse as biology and engi­neering. Net­work sci­en­tists in the lab of Albert-​​László Barabási ana­lyzed how this growth drives tech­no­log­ical break­throughs that improve our lives.
