How plants adjust their photosynthesis to changing light
Photosynthesis is the central process by which plants build up biomass using light, water, and carbon dioxide from the air. Gaining a detailed understanding of this process makes it possible to modify and thus optimize it—for example, with a view t.....»»
A single atom can change the directional profile of the light emitted in scanning tunneling microscopes
Researchers from Madrid explain a phenomenon that allows the direction of light emission to be controlled at the atomic scale. The paper provides a detailed explanation of how the profile of the light collected in a scanning tunneling microscope (STM.....»»
Scientists discover all-optical nuclear magnetic resonance analog with quantum fluids of light
Researchers from Skoltech, the University of Warsaw, and the University of Iceland have demonstrated that by optical means it is possible to excite and stir an exciton-polariton condensate, which emits a linearly polarized light with a polarization a.....»»
Svalbard Global Seed Vault evokes epic imagery and controversy because of the symbolic value of seeds
Two-thirds of the world's food comes today from just nine plants: sugar cane, maize (corn), rice, wheat, potatoes, soybeans, oil-palm fruit, sugar beet and cassava. In the past, farmers grew tens of thousands of crop varieties around the world. This.....»»
Final Venus flyby for NASA"s Parker Solar Probe queues closest sun pass
On Wednesday, Nov. 6, 2024, NASA's Parker Solar Probe will complete its final Venus gravity assist maneuver, passing within 233 miles (376 km) of Venus's surface. The flyby will adjust Parker's trajectory into its final orbital configuration, bringin.....»»
Webb confirms a longstanding galaxy model
Perhaps the greatest tool astronomers have is the ability to look backward in time. Since starlight takes time to reach us, astronomers can observe the history of the cosmos by capturing the light of distant galaxies......»»
Study reveals effect of slope position on nonstructural carbohydrates in biological soil crusts
Nonstructural carbohydrates (NSCs) provide energy for metabolic processes in plants and play a key role in plant growth, defense and osmoregulation. However, the regulation of NSC in biological soil crusts across different slope positions remains unc.....»»
Dams have taken half the water from Australia"s second biggest river—and climate change will make it even worse
The largest wetland on Australia's second longest river, the Murrumbidgee in the southern Murray-Darling Basin, is drying up. This is bad news for the plants, animals and people who rely on the vast Lowbidgee Floodplain. So it's important to understa.....»»
Multi-layered site in Tajikistan"s Zeravshan Valley uncovered, offering new insights into human expansion
In an important discovery, archaeologists from the Hebrew University of Jerusalem and the National Academy of Sciences of Tajikistan have uncovered a multi-layered archaeological site in the Zeravshan Valley, central Tajikistan, shedding rare light o.....»»
Report reveals challenges facing transnational families
A new report from the University of Reading brings to light the unique and often overlooked challenges faced by families living across national borders......»»
Only 3% of South Africans can name all five national animals and plants. Why these symbols matter
Alongside a national flag, anthem and coat of arms, most countries have one or more plant and animal species that they designate as national symbols. The national animal of China, for example, is the giant panda, a nation-wide source of pride and dip.....»»
Computer modeling research reveals the changing history of a global ice sheet
Imagine that a massive ice sheet covered Canada and oozed down over a large part of the northern United States, like icing spilling down the side of a cake. That was the situation somewhere between 19,000 and 26,000 years ago. The ice sheet covered l.....»»

UN summit approves fund to share benefits of nature"s sequenced genetic data
A UN nature summit agreed in Colombia Saturday on the creation of a fund to share the profits of digitally sequenced genetic data taken from animals and plants with the communities they come from......»»
4,000-year-old town discovered hidden in Arabian oasis
The discovery of a 4,000-year-old fortified town hidden in an oasis in modern-day Saudi Arabia reveals how life at the time was slowly changing from a nomadic to an urban existence, archaeologists said on Wednesday......»»
Deep sea rocks suggest oxygen can be made without photosynthesis, deepening the mystery of life
Oxygen, the molecule that supports intelligent life as we know it, is largely made by plants. Whether underwater or on land, they do this by photosynthesizing carbon dioxide. However, a recent study demonstrates that oxygen may be produced without th.....»»
George Lucas abandoned a Star Wars twist that would have changed Obi-Wan’s story
Star Wars: Episode I — The Phantom Menace almost included a game-changing Obi-Wan twist......»»

Earth"s climate will keep changing long after humanity hits net-zero emissions. Our research shows why
The world is striving to reach net-zero emissions as we try to ward off dangerous global warming. But will getting to net-zero actually avert climate instability, as many assume?.....»»
New digital light manufacturing approach resolves common problems associated with 3D printing
A team of materials scientists, medical researchers and engineers affiliated with a large number of institutions across Australia has developed a new way to conduct digital light manufacturing that overcomes problems with current methods. In their pa.....»»
African Sahara "greening" can alter Northern Hemisphere climate, modeling study finds
Africa's Sahara Desert may be considered a vast expanse of barren sand with limited vegetation, an extreme environment for plants and animals to thrive, but life always finds a way. Indeed, vegetation growth in the desert has waxed and waned over mil.....»»
