Perseverance rover finds organic molecules in Mars’ Jezero Crater
The molecules are associated with life but can be created by other processes. So they aren't proof there was life there, but they are life's building blocks......»»
Rise in sea urchins and related damage to kelp forests impacts Oregon"s gray whales and their food, study finds
A recent boom in the purple sea urchin population off the southern Oregon Coast appears to have had an indirect and negative impact on the gray whales that usually forage in the region, a new study shows......»»
Researchers report structure for developing high-efficiency crystalline white organic light-emitting diodes
Organic light-emitting diodes (OLED) have emerged as a new generation of display technology. Organic crystalline materials possess superior thermal stability, chemical stability, and high carrier mobility, making them an ideal choice for developing l.....»»
This EV builder has given a Land Rover Defender four electric hub motors
BEDEO and Protean have been converting commercial vans to hybrid power for some time. Enlarge / The Land Rover Defender has a cult following, and if you're looking to make one electric, there's now one more option. (credit: BEDEO.....»»
Shining a light on molecules: L-shaped metamaterials can control light direction
Polarized light waves spin clockwise or counterclockwise as they travel, with one direction behaving differently than the other as it interacts with molecules. This directionality, called chirality or handedness, could provide a way to identify and s.....»»
Probing small molecule-RNA interactions by looking through the FOREST
A team of researchers has recently demonstrated the utility of employing a previously established screening system to probe the interactions between small molecules and RNA. Their study is published in Communications Chemistry......»»
Homo sapiens facilitated establishment of Bonelli"s eagle in the Mediterranean 50,000 years ago, study finds
Spanish and Portuguese scientists have unraveled the ancestral history of one of the most iconic birds of prey in the current Iberian fauna, the Bonelli's eagle (Aquila fasciata). The work, published in the journal People and Nature, integrates evide.....»»
Study shows alkyl-aromatic hybrid micelles can form from emergent umbrella-shaped molecules
Micelles assemble in water from amphiphilic molecules, composed of hydrophilic and hydrophobic frameworks. They can be found all around us, for example in soaps, detergents, and shampoos. Their main application is the water-solubilization of insolubl.....»»
Legacy of Indigenous stewardship of camas dates back more than 3,500 years, study finds
An Oregon State University study has found evidence that Indigenous groups in the Pacific Northwest were intentionally harvesting edible camas bulbs at optimal stages of the plant's maturation as far back as 3,500 years ago......»»
Appropriate exercise is an important part of crew health during space missions
Future missions to the moon and Mars must address many challenges, including preventing loss of bone and muscle tissue in astronauts. Research on the International Space Station is helping to address this challenge......»»
Illegitimate interruptions reduce productivity in the workplace, finds study

M4 iPad Pro teardown finds easier-to-access battery, glimpses of Tandem OLED design
Straightforward tablet teardown is followed by a comically difficult Pencil one. iFixit's M4 iPad Pro teardown. Right on schedule for past releases, iFixit has done a teardown of Apple's new, redesigned iPad Pro. It found that the i.....»»
Is gig work compatible with employment status? Study finds reclassification benefits both workers and platforms
As California legal challenges to the treatment and classification of so-called gig work continues apace, a Massachusetts trial over the same issues touched off this week......»»
Study finds cloudy waters may drive African fish to develop bigger eyes
Variations in water quality can impact the development of the visual system of one species of African fish, suggests a new study......»»
Seeing the color of entangled photons in molecular systems
Spectroscopy is the study of how matter absorbs and emits light and other radiation. It allows scientists to study the structure of atoms and molecules, including the energy levels of their electrons. Classical optical spectroscopy relies on the way.....»»
Alaska"s rusting waters: Pristine rivers and streams turning orange
Dozens of Alaska's most remote streams and rivers are turning from a crystal clear blue into a cloudy orange, and the staining could be the result of minerals exposed by thawing permafrost, finds new research in Communications Earth & Environment......»»
Astronomers determine Mars may face more potentially hazardous asteroids than Earth
A team of astronomers at Nanjing University has found evidence that Mars likely has more potentially hazardous asteroids in its path than Earth. In their study, posted on the arXiv preprint server, the group investigated the number of potentially haz.....»»
Gender gaps remain for many women scientists, study finds
As more women have entered the biomedical field, they're getting a bigger share of research grants, and the gender gap in research funding appears to be narrowing, but the gains have been uneven......»»
Exploring extremes in the search for life on Mars
People might assume the search for life on Mars ended when NASA's first rovers sent back images of the planet's barren, inhospitable surface. However, as scientists broaden their understanding of the extreme conditions in which life can flourish here.....»»
Study finds evidence that subduction zone splay faults compound hazards of great earthquakes
Research has provided new insight into the tectonic plate shifts that create some of the Earth's largest earthquakes and tsunamis......»»
NASA spacecraft spots dead robot on Mars surface
NASA's Mars Reconnaissance Orbiter viewed the space agency's retired InSight lander as it gradually collects dust in the Martian desert. Mars is collecting artifacts.Without the large, powerful camera aboard NASA's Mars Reconnaissance Orbiter,.....»»
