Team from Guangzhou Institutes of Biomedicine and Health say technique was successful in treatment of mice.
We’re currently in dire need of new weapons against infectious bacteria, especially those in a tough-to-kill class known as gram-negative bacteria. Now, researchers at Northeastern University have discovered just that, hiding in the gut of a tiny, soil-dwelling, parasitic worm. Tests on mice have so far proved promising.
For decades we’ve had the upper hand over bacteria, clearing out many infections fairly easily with antibiotics. But extensive use has led to an arms race between us and bacteria. As they evolve resistance to our best drugs, we develop new ones and use those until the bugs become resistant to those too.
But this cycle is starting to break down, and not in our favor. Developing new drugs is time and cost-intensive process, and bacteria are evolving resistances faster than we can keep up. There are now “superbugs” that are resistant to all known drugs. The situation is getting so bad that a recent report warned that superbugs could kill up to 10 million people a year by 2050, casting us back into the “dark ages of medicine.”
Cornell researchers have made a new discovery about how seemingly minor aspects of the internal structure of bone can be strengthened to withstand repeated wear and tear, a finding that could help treat patients suffering from osteoporosis. It could also lead to the creation of more durable, lightweight materials for the aerospace industry.
The team’s paper, “Bone-Inspired Microarchitectures Achieve Enhanced Fatigue Life,” was published Nov. 18 in the Proceedings of the National Academy of Sciences. Co-authors include Cornell doctoral students Cameron Aubin and Marysol Luna; postdoctoral researcher Floor Lambers; Pablo Zavattieri and Adwait Trikanad at Purdue University; and Clare Rimnac at Case Western Reserve University.

New study shows how patterns in brain activity can be an early predictor of Alzheimer’s symptoms.
Paolo Sanvito would often freeze like a statue after entering a meeting room when he was working as a manager in a multinational company. Known as freezing of gait, it’s a disabling symptom of Parkinson’s disease, a degenerative brain disorder that he suffers from.
Researchers at Northeastern have discovered a new antibiotic that could treat infections caused by some of the nastiest superbugs humanity is facing in the antibiotic resistance crisis.
For years, researchers weren’t exactly sure what to make of these extra loops of genetic material. That’s quickly changing.
