More ‘heatwave’ summers will affect animals

Heatwaves similar to those experienced in Europe in 2018 can have a very negative impact on animals. A new study shows that overheated birds have smaller offspring, and that those that are born may have lower chances of survival.

What social stress in monkeys can tell us about human health

A new study examines one key stress-inducing circumstance -- the effects of social hierarchy -- and how cells respond to the hormones that are released in response to that stress.

Hypoxic dead zones found in urban streams, not just at the coast

A new study finds that hypoxic dead zones occur in nutrient-laden urban streams, not just in coastal waters. The research shows that intense storm flows can erode some stream channels to become a series of pools that trap nutrient-laden runoff. The elevated nutrient levels in the water spur greater consumption of dissolved oxygen by bacteria, causing the pools to become hypoxic until the next storm flushes them out.

Historic earthquakes test Indonesia’s seismic hazard assessment

Using data gleaned from historical reports, researchers have now identified the sources of some of the most destructive Indonesian earthquakes in Java, Bali and Nusa Tenggara, using these data to independently test how well Indonesia's 2010 and 2017 seismic hazard assessments perform in predicting damaging ground motion.

Small and isolated habitat patches crucial to species survival

Small, local patches of habitat could be playing a much bigger role in conserving biodiversity than you think, according to new research.

Ocean fertilization by unusual microbes extends to frigid waters of Arctic Ocean

Microbes that provide natural fertilizer to the oceans by 'fixing' nitrogen from the atmosphere into a form useable by other organisms are active in the cold waters of the Bering and Chukchi Seas.

How will the winds of climate change affect migratory birds?

Under future climate scenarios, changing winds may make it harder for North American birds to migrate southward in the autumn, but make it easier for them to come back north in the spring. Researchers came to this conclusion using data from 143 weather radar stations to estimate the altitude, density, and direction birds took during spring and autumn migrations over several years.

A code for reprogramming immune sentinels

For the first time, a research team has successfully reprogrammed mouse and human skin cells into immune cells called dendritic cells. The process is quick and effective, representing a pioneering contribution for applying direct reprogramming for inducing immunity. Importantly, the finding opens up the possibility of developing novel dendritic cell-based immunotherapies against cancer.

Magnetic reconnection in space: Experiment and satellite sightings

New research describes striking similarity of laboratory research findings with observations of the four-satellite Magnetospheric Multiscale Mission that studies magnetic reconnection in space.

The privacy risks of compiling mobility data

A new study finds that the growing practice of compiling massive, anonymized datasets about people's movement patterns is a double-edged sword: While it can provide deep insights into human behavior for research, it could also put people's private data at risk.
