Is Progress Outpacing Precaution? Experts Weigh In

Illustration by An Arres.

No one expects the machinery of progress to roll backwards, but sometimes it seems that no one is watching the speedometer (or manning the brakes, assuming any exist).  Is this a fair assessment? If so, should we be worried — and what can we do about it?

In this feature, experts on technology, risk, science, policy and neuroscience discuss risk, innovation and how our values affect our conceptions of both.

Genome Map Hints at How Desert Tortoise Overcomes Natural, Human Dangers

Researchers have finished the first full genome map of the threatened Mojave desert tortoise (Gopherus agassizii), also known as Agassiz’s desert tortoise.

They hope their findings will inform conservation efforts, improve understanding of its evolutionary past and potentially contribute  to  human medicine.

For Pancreatic Cancer, Biomarker Test Offers Chance for Early Detection

When cancer is detected,  the interaction of two nanoparticles creates a bright yellow signal (photo by Fei Lu, Houston Methodist Research Institute).

Pancreatic cancer is the fourth leading cause of cancer deaths in the United States each year, in part because around four-fifths of cases go undetected until they have reached an advanced stage. But a new, biomarker-based test could soon change all that — and offer a way to monitor treatment outcomes.

Mitochondria-Linked Genetic Changes Might Give Early Hint of Alzheimer’s Disease

Long before they develop neurofibrillary tangles or beta-amyloid plaques, brains with Alzheimer’s disease begin experiencing problems in their cells’ power plants — the mitochondria — that hinder their ability to make energy for cells.

Declines in gene expression related to mitochondria can occur in subjects as young as their early 30s.

Drug Targets Offer Hope for Less Painful, More Survivable Pancreatic Cancer

Scientists have identified drug targets that could one day make pancreatic cancer less painful — and more survivable — by knocking out key molecular signals. The signals form an essential part of the process by which cancer cells invade and spread through nearby nerves, wounding nerve endings.
