We summarize the week's scientific breakthroughs every Thursday.
- Science & Society
In science, a lack of replication shouldn’t kill your reputation
The proof is science is when a study is replicated. When it’s not, do scientists suffer? A new study says researchers may overestimate the negative effects.

Anatomy of the South Korean MERS outbreak
The Middle East respiratory syndrome virus, which infected 186 people in South Korea in 2015, quickly spread within and between hospitals via a handful of “superspreaders.”

Cow bites and spacecraft injuries enliven new medical diagnostic codes
The 10th edition of International Classification of Diseases went into effect in 2015, and it included some interesting additions.
- Anthropology
Thigh bone adds to mystery over 14,000-year-old Homo species
Controversial Chinese leg fossil may point to hybrid humans 14,000 years ago.
- Health & Medicine
To treat the heart, start with the gut
Preventing gut bacteria from making certain chemical compounds reduced artery clogging in mice, researchers report.

Year in review: Not all bodies act their age
People grow old at different rates, but the underlying drivers of aging may be the same: molecular havoc wreaked inside of cells, scientists suggested in 2015.
- Neuroscience
Year in review: Alzheimer’s protein behaves like a prion
