Phys.org / Rising seas could weaken Chesapeake Bay's natural storm surge buffer
A hurricane does not have to make a direct hit to affect the Chesapeake Bay. Even from out at sea, a hurricane's winds, waves and rising tides can cause major flooding.
Phys.org / Jamming the flow to enable memory in quantum materials
Understanding and controlling phase transitions are fundamental to physics and central to many technological revolutions. There is currently strong interest in materials with coupled structural and electronic phase transitions, ...
Phys.org / U.S. methane emissions flatline, despite increases in oil and gas production
Methane emissions from the oil and gas sector held steady in the United States even as oil and gas production increased during a recent period of heightened regulations, according to new research from Johns Hopkins University.
Phys.org / Ancient climate shifts may explain why today's flowering plants are so diverse
The two warmest time periods on Earth in the past 140 million years drove both mass extinctions and explosions in plant diversity, according to researchers in Australia and Austria who say this could explain how flowering ...
Phys.org / Sustained pressure halts cancer cell migration and triggers death in 3D lab models
The growth and death of cancer cells in the lab are studied primarily in two-dimensional cell cultures. In a study published in the journal Developmental Cell on Oct. 14, researchers instead used three-dimensional models ...
Phys.org / Fighting off microbial invasions drains plants' iron stores, but one protein helps restore balance
Energy production in our cells, oxygen traveling in our blood and immune cells fighting infection all depend on iron, an essential mineral that enters the food chain when plants absorb it from soil. But iron is often scarce—likely ...
Phys.org / Ivy bees fight back against honeybees that drive other pollinators off flowers
Honeybees are outcompeting wild pollinators in the U.K., and new research has found evidence of their aggressive behavior, recording for the first time the extent to which they restrict access to food sources and attack and ...
Phys.org / Local DNA motion inside the cell stays nearly constant throughout interphase
Human genomic DNA is wrapped around core histone proteins to form nucleosomes, the fundamental units of chromatin. During interphase, the period between cell divisions, DNA is replicated and the nucleus becomes larger. At ...
Phys.org / Modeling study shows early tetrapods had surprisingly little ability to move their necks
A new model using sturgeon as a material analog has made it possible to estimate how the backbones of some of the first animals on land could and could not move. These results disprove a long-standing hypothesis that changes ...
Phys.org / How shark ecotourism sparks long-term conservation
People who join shark ecotourism tours are more likely to take action to protect sharks, including donating to related causes, signing petitions or speaking up online, new research from the University of Sydney shows.
Phys.org / Could a molecular ZIP code unlock treatments for untreatable diseases?
Imagine a medicine that stops seizures at their source, switches off instructions that keep a cancerous tumor growing and prevents Alzheimer's from stealing memories and wreaking havoc on the brain.
Phys.org / New DNA tool could help detect harmful algal blooms before they spread
A new study by researchers at the University of South Florida and Florida Atlantic University has demonstrated that a DNA sequencing tool can rapidly identify harmful algae in coastal waters, offering a new approach for monitoring ...
