Phys.org / Resilience bonds could serve as an insurance solution to address climate change risks
Researchers with Lehigh University's Center for Catastrophe Modeling and Resilience, led by anthropologist David G. Casagrande, have identified two urgent challenges the United States faces in adapting to climate change: ...
Phys.org / How bacteria learned to target numerous cell types
Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and bind to receptors on the surface of target cells, a molecular arms race that drives constant evolution. ...
Phys.org / New class of catalysts could dramatically change playing field in nickel catalysis
Researchers at the University of Illinois Urbana-Champaign have reported a breakthrough in nickel catalysis that harnesses a rare oxidation state of nickel that has proved challenging to control yet is highly valued for its ...
Phys.org / Nanotubes with lids mimic real biology
When water and ions move together through channels only a nanometer wide, they behave in unusual ways. In these tight spaces, water molecules line up in single file. This forces ions to shed some of the water molecules that ...
Phys.org / Biologists discover alternative systems that help cells control genes
Researchers at the School of Biological Sciences of The University of Hong Kong (HKU) have uncovered how eukaryotic cells can control gene activity even after losing one of their major gene-regulatory systems during evolution. ...
Phys.org / New formula unravels vines' parasitic nature
Twisting upwardly on trees and other plants—along with houses and even lampposts—vines are a wonder of nature. However, their marvels mask their parasitic behavior: in attaching to other life forms, vines block sunlight ...
Phys.org / Bigger is not always better: Smaller leaves optimize light use in soybeans
In efforts to better understand how soybean plants capture and use light, researchers at the University of Illinois Urbana-Champaign investigated how leaf size and shape affect light distribution within the crop canopy. Using ...
Phys.org / 'Northwest Passage' mechanism of bile acid transport reveals a voltage-dependent pathway
In a study published in Nature on January 28, a research team led by Eric H. Xu (Xu Huaqiang) from the Shanghai Institute of Materia Medica of the Chinese Academy of Sciences, along with Ma Xiong from Renji Hospital, determined ...
Phys.org / Analyzing an enigmatic enzyme with potential for new antibiotic drug discovery
An analysis of an unusual enzyme could result in a new generation of antimicrobial medicines to counter antibiotic resistance. Key details in the enzyme-driven biosynthesis of a natural molecule with potent antibiotic activity ...
Phys.org / Imaging the Wigner crystal state in a new type of quantum material
In some solid materials under specific conditions, mutual Coulomb interactions shape electrons into many-body correlated states, such as Wigner crystals, which are essentially solids made of electrons. So far, the Wigner ...
Phys.org / Two rare 5th millennium BC fetal burials in Iran reveal variable prehistoric practices
In a study conducted by Dr. Mahdi Alirezazadeh and Dr. Hanan Bahranipoor, published in Archaeological Research in Asia, two exceptionally well-preserved fetal burials from Chaparabad, Iran, dating to the mid-5th millennium ...
Phys.org / Tropical weather cycles linked to faster Arctic ice loss in autumn
When it comes to global warming and climate change, we often hear news stories about tipping points where Earth's systems shift into a new and dangerous state. One such may have been reached in the year 2000 that caused tropical ...
