Protein involved in nematode stress response identified
When humans experience stress, their inner turmoil may not be apparent to an outside observer. But many animals deal with stressful circumstances -- overcrowded conditions, not enough food -- by completely remodeling their bodies. These stress-induced forms, whether they offer a protective covering or more camouflaged coloration, can better withstand the challenge and help the animal survive until conditions improve.

Origins of Pain
Research in mice identifies a set of neurons responsible for sustained pain and resulting pain-coping behaviors Findings point to the existence of separate neural pathways that regulate threat avoidance versus injury mitigation Study can inform new ways to gauge the efficacy of candidate pain therapies by assessing behaviors stemming from different pathways.

New interactions between Ebola virus and human proteins discovered
Several new connections have been discovered between the proteins of the Ebola virus and human host cells, a finding that provides insight on ways to prevent the deadly Ebola virus from reproducing and could lead to novel ways to fight these lethal viral infections, according to a new study.

Novel mechanisms of dengue and Zika virus infections and link to microcephaly
New insights into how dengue and Zika viruses cause disease reveal strategies the viruses use to successfully infect their host and a link to microcephaly.

New drug seeks receptors in sarcoma cells, attacks tumors in animal trials
A new compound that targets a receptor within sarcoma cancer cells shrank tumors and hampered their ability to spread in mice and pigs, a study reports. The researchers conducted a multi-year, cross-disciplinary study that went from screening potential drug candidates to identifying and synthesizing one compound, to packaging it into nanoparticles for delivery in cells, to testing it in cell cultures and finally in mice and pigs with sarcoma tumors.

Drug targets for Ebola, Dengue, and Zika viruses found in lab study
No drugs are currently available to treat Ebola, Dengue, or Zika viruses, which infect millions of people every year and result in severe illness, birth defects, and even death. Scientists may finally change that. They identified key ways the three viruses hijack the body's cells, and they found at least one potential drug that can disrupt this process in human cells.

Amyloid pathology transmission in lab mice and historic medical treatments
A study has confirmed that some vials of a hormone used in discontinued medical treatments contained seeds of a protein implicated in Alzheimer's disease, and are able to seed amyloid pathology in mice.
