Acoustic propulsion of nanomachines depends on their orientation
Microscopically tiny nanomachines which move like submarines with their own propulsion—for example in the human body, where they transport active agents and release them at a target: What sounds like science fiction has, over the past 20 years, bec.....»»

Sexual orientation and earnings appear to be linked, patterns differ for NZ men and women
New Zealand has made substantial progress on promoting LGBTQ+ rights over the past 20 years, including legalizing same-sex civil unions in 2004, legalizing same-sex marriage in 2013, and banning conversion practices in 2022......»»
For its final trick, Chandrayaan-3 brings its propulsion module to Earth orbit
On August 23, ISRO's Vikram lander detached from its propulsion module and made a soft landing near the moon's south pole region. The lander then deployed its Pragyan rover, and for two weeks the endearing little solar-powered rover performed marvelo.....»»
Exploring acoustic design for better, quieter prisons
Prisons are typically noisy environments, filled with clanking metal bars and echoing concrete surfaces. This level of constant noise is harmful to both prisoners and staff, but there are few guidelines for designing better, quieter facilities......»»
India reveals that it has returned lunar spacecraft to Earth orbit
India now credibly has the third most advanced deep-space program in the world. Enlarge / India's Chandrayaan-3 lunar spacecraft undergoes accoustic testing. The propulsion module can be seen at the bottom. (credit: ISRO).....»»
Low emissions and economic survival—countries in the global south aren"t getting a fair deal
In 2015, more than 140 countries signed up to the goal of achieving net-zero emissions by 2050. For countries in the global south this is a huge task. On the one hand, they have committed to low emissions. On the other their economic survival depends.....»»

Why the success of COP28 depends on climate finance
Beginning this week, leaders from more than 190 countries will gather in Dubai for COP28, the annual climate global summit. This year, the stakes have never been higher: wildfires in Maui, partly exacerbated by drought, killed at least 100 people and.....»»
Plants found to recruit distinct chemical activities of coumarins under different soil pHs
Plants have two main uptake mechanisms to obtain iron (Fe) from the soils. The type of strategy employed depends on the botanical classification of the plant. In the so-called strategy-I mechanism, plants must first reduce the trivalent iron (Fe3+) i.....»»
New automatic algorithm unveils key insights into leaf orientation and plant productivity
Maize (Zea mays L.), the most globally produced cereal, owes its enhanced productivity to genetic, agronomic, and climatic factors, with cultivars adapted to higher density playing a crucial role. Recent research has focused on maize's architectural.....»»
Human rights law demands climate change adaptation, researchers say
Continued high emissions of greenhouse gases mean the well-being of all people now depends on profound changes in policies and practices to effect climate change adaptation......»»
More is not always better, even when it comes to digital platforms
As with the business of logistics, where having multiple routes to deliver goods to the same destination raises reliability, network-dependent consumerism depends on multiple networks having a host computer with multiple connections operating in sync.....»»
NASA uses two worlds to test future Mars helicopter designs
For the first time in history, two planets have been home to testing future aircraft designs. In this world, a new rotor that could be used with next-generation Mars helicopters was recently tested at NASA's Jet Propulsion Laboratory in Southern Cali.....»»
Global view of Io"s volcanic activity suggests that tidal heating is concentrated within its upper mantle
A team of volcanologists and planetary scientists from NASA's Jet Propulsion Laboratory, California Institute of Technology, the University of Arizona, and Arizona State University has found via study of a newly created global view of Io's volcanic a.....»»
Better capturing the effect of aerosol particles on clouds and the climate
The extent to which aerosol particles affect the climate depends on how much water the particles can hold in the atmosphere. The capacity to hold water is referred to as hygroscopicity (K) and, in turn, depends on further factors—particularly the s.....»»
Acoustic diffraction-resistant adaptive profile technology for elasticity imaging
Acoustic beam shaping with high degrees of freedom is critical for ultrasound imaging, acoustic regulation, and stimulation. The ability to fully regulate the acoustic pressure profile relative to its propagation path remains to be achieved......»»
New study shows how authors" personal circumstances influence the depiction of nature in their works
Novels and poems often contain descriptions of plants or animals—sometimes more, sometimes less detailed. The extent to which flora and fauna feature in a literary work also depends on who wrote it and under what circumstances......»»
