Science

• A Tel Aviv University study argues the Qumran sect behind the Dead Sea Scrolls really did follow its unusual 364-day calendar — which divides evenly into 52 seven-day weeks — in its early years, before abandoning the system later as impractical; published in Tarbiz Quarterly for Jewish Studies by Prof. Eshbal Ratzon.
• Researchers report that cats carry a durable chemical "calling card" in their urine made of 13 branched-chain fatty acids whose mix varies cat to cat but stays consistent within one animal, tied to long-mysterious fat droplets in feline kidneys; the study is due in Current Biology.

Health & medicine
