Ending Net Neutrality

Politics Technology Law

The Federal Communications Commission (FCC) decided to remove laws that protect net neutrality. Net neutrality is the result of laws that have been in effect for 2 years that prohibit Internet service providers from speeding up or slowing down any websites you use. Without net neutrality, Internet service providers could go from being neutral gateways to gatekeepers. There are differences in opinion about whether this will be helpful for consumers or the economy. Listen to hear from the former FCC chairman about his thoughts on an open Internet.

Debate: Should Doctors Separate Conjoined Twins to Save One?

Ethics

Doctors faced an ethical dilemma recently in a case of conjoined twins. They had separate heads and torsos, but they were connected at the abdomen and the pelvis. They shared a liver and a bladder and other organs, and had just three legs in all. One of the twins had heart and lung disease so serious that she was likely to die soon, and as a result, her sister would die in the process. Listen to hear how doctors discussed what to do in this situation and then debate: Should doctors separate conjoined twins to save one of them?

What happens when human structures and nature come into conflict? Ocean Beach in San Francisco is naturally eroding, but the consequence of this shifting shoreline is that a sewage treatment plant is put in peril. Without intervention, raw sewage could be dumped into the ocean. A rock wall has temporarily stabilized the pipeline, but not without complications. Now other solutions are being considered, including construction of an artificial dune.

Clinical Trials Don’t Reflect the Diversity of America

Life Science Race Gender Genetics

American doctors rely on clinical trials to determine which drugs to use in treatment. Researchers have found that clinical trials have not been effective in creating drugs for America’s diverse population. When clinical trials are too homogeneous, they can leave important discoveries undiscovered. Patients who are diverse ethnically and racially can respond differently to medications, leading to dire consequences. Listen to learn how a lack of diversity in clinical trials affects patients and how researchers are trying to fix it.

Tsunami Warnings Get More Accurate

Earth and Space Science Weather and Climate Physical Science Forces and Newton's Laws

Tsunamis are created by tectonic plates thrusting against each other and then lifting the sea floor and dropping it down, which creates a giant wave. A 2010 earthquake in Chile was caused by a shift in the seafloor. This same shift set off tsunami detection buoys and left scientists waiting for the tsunami to hit. But it ended up being small. Listen to learn more about this quake and how tsunamis are created.

Manatees, the vegetarian aquatic mammals that inhabit the waters of Florida, depend on natural warm water springs to survive the winter. But as a consequence of greater development, those warm water sources have diminished over the years. So manatees have come to depend on the warm water discharge of power plants. But now, they face losing these man-made refuges as power plants strive to be more efficient and environmentally friendly.

An estimated 1 in 13 children have food allergies. Some are potentially life-threatening and avoiding the allergen can be challenging and stressful. The blood tests and skin prick tests rule out specific food allergies but are not as accurate when confirming food allergies. The oral food challenge, where the food is eaten under the supervision of a doctor has become the gold-standard for determining allergies.
