Borrowing from both “Dracula” and “Alien,” this satellite phage evolved a short appendage that allows it to latch onto its helper’s neck like a vampire.

We don’t yet know how MiniFlayer subdues its helper, or whether MindFlayer has evolved countermeasures."

This patient was consuming a diet high in saturated fats, including red meats, eggs, and coconut oil. 2   A behavioral modification approach was appropriate because she had multiple areas for improvement in her diet and no history of diabetes, cardiovascular disease, or hypertension. However, this conservative approach may not be appropriate for patients with cardiovascular risk factors and/or genetic hypercholesterolemia. This nutritional approach is especial...
