In a rare surgery in India, a seven-year-old cat named Pillu received a pacemaker at a Pune veterinary clinic on Monday. Pillu's heart rate had dangerously dropped to the 50s, far below the normal ...

NEW YORK, May 5 (Reuters Breakingviews) - Oil fields are just as quick to make fortunes as break them. The 1901 Spindletop gusher in Texas jumpstarted the petroleum age, crashing oil prices.

Natural gas is increasingly becoming a key player in the global energy mix. For companies focused on drilling oil and natural gas, the future of natural gas looks bright. Here’s why investing in ...

The current standard in temporary pacemakers (called an “epicardial” pacemaker) involves sewing electrodes to the heart via wires, which then protrude out of the patient’s chest and connect ...
