Nucleo-cytoplasmic interaction in seedless cybrid citrus
Male sterility is important for seedless citrus breeding. A long juvenile phase and nucellar polyembryony leads to low efficiency of hybrid breeding in citrus. The Citrus research group in National Key Laboratory for Germplasm Innovation & Utilizatio.....»»
Nutrient uptake in citrus rootstock affected by huanglongbing
Huanglongbing (HLB) is presumably caused by the phloem-limited bacteria, Candidatus Liberibacter asiaticus (CLas), and is one of the most devastating diseases of citrus. A distinctive chlorotic mottle on fully expanded leaves is one of the identifyin.....»»
Fungi that causes pine ghost canker detected in southern California trees
Fungal pathogens that cause die-back in grape, avocado, citrus, nut and other crops has found a new host and is infecting conifer trees causing Pine Ghost Canker in urban forest areas of Southern California......»»
Writing on glass and silica indicates novel direction for chiral optical property tailoring
From fundamental physics of light-matter interaction to fabrication of targeted optical properties in highly complex optical engineering, the femtosecond (fs) laser plays a crucial role in laser manufacturing. Ultrashort light pulses can precisely de.....»»
Is kindness contagious?
Imagine that you're approaching your favorite coffee shop, when your eyes are suddenly drawn toward an interaction between two strangers happening just outside its doors. One man sits, leaning against the glass window, knees drawn to his chest, a pla.....»»
‘I want to be human.’ My intense, unnerving chat with Microsoft’s AI chatbot
Microsoft's AI chatbot, Bing Chat, is slowly rolling out to the public. But our first interaction shows it's far from ready for a full release......»»
Interaction between two filaments plays a key role in sympathetic filament eruptions
Solar sympathetic filament eruptions usually involve two or more filament eruptions that occur simultaneously or successively within a relatively short time interval with a certain causal linkage. The eruption of one filament may have an effect on an.....»»
Fishing in synchrony brings mutual benefits for dolphins and people in Brazil, research shows
By working together, dolphins and net-casting fishers in Brazil each catch more fish, a rare example of an interaction by two top predators that is beneficial to both parties, researchers have concluded following 15 years of study of the practice......»»
Mie voids could bring about control of light in air
Resonant optical phenomena in metals and dielectrics have profound applications in many fields. The nanoscale confinement allows for unpreceded control of light-matter interaction at surfaces and interfaces, manipulating and controlling the light flo.....»»
Tyre Nichols" killing by police: Why is this still happening?
Video footage was released today of the interaction between Memphis police officers and Tyre Nichols, a 29-year-old Black man who died just days after being beaten by police during a Jan. 7 traffic stop......»»
Starry tail tells the tale of dwarf galaxy evolution
A giant diffuse tail of stars has been discovered emanating from a large, faint dwarf galaxy. The presence of a tail indicates that the galaxy has experienced recent interaction with another galaxy. This is an important clue for understanding how so.....»»
"Friend or foe" bacteria kill their algal hosts when coexisting is no longer beneficial
Scientists have detailed a lifestyle switch that occurs in marine bacteria, in which they change from coexisting with algae hosts in a mutually beneficial interaction to suddenly killing them. The results are published today in eLife......»»
Solid Earth-atmosphere interaction forces during the Hunga Tonga-Hunga Ha"apai volcanic eruption
The submarine volcano eruption of Hunga Tonga-Hunga Ha'apai that occurred on January 15, 2022, generated impulsive downward reaction forces on Earth, radiating seismic waves throughout the planet. Geologists analyzed the teleseismic waves and Rayleig.....»»
Online interaction is impacting the mood and cognitive function of young people, says study
The potential for being judged online could be affecting the ability of adolescents to concentrate on everyday tasks, a study by UNSW Sydney researchers finds......»»
VividQ partners with Dispelix to improve AR interaction with 3D objects
VividQ, a Cambridge-based holographic display technology company, announced on January 17 that it is partnering with Dispelix, a Finnish waveguide supplier, to produce a breakthrough augmented reality (AR) technology that will bring AR experience to.....»»
A legume locus stimulates promiscuous interaction with soil bacteria
While promiscuity among humans is often scorned, symbiotic promiscuity can be a sign of excellent teamwork in other species. Plant growth, especially in legumes, flourishes through mutualistic interactions with soil bacteria, commonly known as rhizob.....»»
Innovation strengthens electron-triggered light emissions for quantum-based computational and communications systems
The way electrons interact with photons of light is a vital part of many modern technologies, from lasers to solar panels to LEDs. But the interaction is inherently weak because of a major mismatch in scale: the wavelength of visible light is about 1.....»»
Differential dynamics and direct interaction of bound ligands with lipids in multidrug transporter ABCG2
ABC transporters constitute a major class of multidrug resistance proteins, e.g., in cancer cells. Membrane lipids have been long known to influence the structure and functional dynamics of these proteins. However, previous structural and biochemical.....»»
Scientists find iron cycling key to permafrost greenhouse gas emissions
The interaction of elemental iron with the vast stores of carbon locked away in Arctic soils is key to how greenhouse gases are emitted during thawing and should be included in models used to predict Earth's climate, Oak Ridge National Laboratory sci.....»»
Squeezing microwave fields by magnetostrictive interaction
Squeezed states of the electromagnetic field find many important applications in quantum information science and quantum metrology. Dr. Jie Li et al. at Zhejiang University put forward a new mechanism for preparing microwave squeezed vacuum states us.....»»
Anatomy of a superorganism: Ant pupae secrete fluid as "milk" to nurture young larvae
Life in an ant colony is a symphony of subtle interactions between insects acting in concert, more like cells in tissue than independent organisms bunking in a colony. Now, researchers have discovered a previously unknown social interaction that unit.....»»
