Each year, hundreds of thousands of people visit Mendenhall Glacier—an easily accessible glacier near Juneau in Southeast Alaska.
Gray Whales Feeding Along the Pacific Northwest Coast Are Smaller Than Their Counterparts Who Travel Farther to Forage
Gray whales that spend their summers feeding off the coast of Oregon are shorter than their counterparts who travel north to the Arctic for food, new research from Oregon State University’s Marine Mammal Institute shows.
An Unexpected Way to Upcycle: Plastic Waste Transforms Into Soap
A team led by Virginia Tech researchers has developed a new method for upcycling plastics into high-value chemicals known as surfactants, which are used to create soap, detergent, and more.
Researchers engineer bacteria that can detect tumor DNA
Creating new technologically advanced sensors, scientists have engineered bacteria that detect the presence of tumor DNA in live organisms. Their innovation could pave the way to new biosensors capable of identifying various infections, cancers and other diseases.
The positional transmitter of statoliths unveiled: It keeps plants from getting lazy
Plants orient their organs in response to the gravity vector, with roots growing towards gravity and shoots growing in the opposite direction. The movement of statoliths responding to the inclination relative to the gravity vector is employed for gravity sensing in both plants and animals. However, in plants, the statolith...
New Research Confirms Land-Sea Relationship Is Major Driver of Coral Reef Health Outcomes
Climate change has long been considered as one of the greatest drivers of declining coral reefs, but the specifics of human impact have been largely unverified.
Telecommunications Cable Used to Track Sea Ice Extent in the Arctic
A telecommunications fiber optic cable deployed offshore of Oliktok Point, Alaska recorded ambient seismic noise that can be used to finely track the formation and retreat of sea ice in the area, researchers report in The Seismic Record.
Then vs. Now: Did the Horn of Africa Reach a Drought Tipping Point 11,700 Years Ago?
‘Wet gets wetter, dry gets drier’. That mantra has been used for decennia to predict how global warming will affect the hydrological cycle in different world regions.
Researchers find new pathway for HIV invasion of cell nucleus
A study has identified a new pathway that human immune deficiency virus (HIV) uses to enter the nucleus of a healthy cell, where it can then replicate and go on to invade other cells.
