Orchid without bumblebee on island finds wasp, loses self      (via sciencedaily.com)     Original source 

Because the bumblebee that an orchid relies on for pollination does not exist on a remote island, the plant gets pollinated by an island wasp. Researchers found that this came at the cost of being hybridized with another orchid species adapted to being pollinated by the wasp. The finding showcases how plants in ecological relationships adapt to changing circumstances.

Scientists, philosophers identify nature's missing evolutionary law      (via sciencedaily.com)     Original source 

A new article describes 'a missing law of nature,' recognizing for the first time an important norm within the natural world's workings.   In essence, the new law states that complex natural systems evolve to states of greater patterning, diversity, and complexity. In other words, evolution is not limited to life on Earth, it also occurs in other massively complex systems, from planets and stars to atoms, minerals, and more.

Climate change coping mechanism discovered in humble algae      (via sciencedaily.com)     Original source 

One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops.

What phytoplankton physiology has to do with global climate      (via sciencedaily.com)     Original source 

Phytoplankton, tiny photosynthetic organisms in the ocean, play a crucial role in the global carbon cycle and influence Earth's climate. A new study reveals how variations in the physiology of phytoplankton, particularly regarding nutrient uptake, can impact the chemical composition of the ocean and even the atmosphere. This suggests that changes in marine phytoplankton physiology can affect global climate.

NASA's Webb captures an ethereal view of NGC 346      (via sciencedaily.com)     Original source 

One of the greatest strengths of NASA's James Webb Space Telescope is its ability to give astronomers detailed views of areas where new stars are being born. The latest example, showcased here in a new image from Webb's Mid-Infrared Instrument (MIRI), is NGC 346 -- the brightest and largest star-forming region in the Small Magellanic Cloud.

Mummified feces reveals pre-Columbian cultures of the Caribbean consumed a diversity of plants      (via sciencedaily.com)     Original source 

DNA analysis of mummified feces reveals two pre-Columbian Caribbean cultures ate a wide variety of plants, like maize, sweet potato, and peanuts -- and tobacco and cotton traces were detected too, according to a new study.

'Starquakes' could explain mystery signals      (via sciencedaily.com)     Original source 

Fast radio bursts, or FRBs, are an astronomical mystery, with their exact cause and origins still unconfirmed. These intense bursts of radio energy are invisible to the human eye, but show up brightly on radio telescopes. Previous studies have noted broad similarities between the energy distribution of repeat FRBs, and that of earthquakes and solar flares. However, new research has looked at the time and energy of FRBs and found distinct differences between FRBs and solar flares, but several notable similarities between FRBs and earthquakes. This supports the theory that FRBs are caused by 'starquakes' on the surface of neutron stars. This discovery could help us better understand earthquakes, the behavior of high-density matter and aspects of nuclear physics.

Finding explanation for Milky Way's warp      (via sciencedaily.com)     Original source 

Though scientists have long known through observational data that the Milky Way is warped and its edges are flared like a skirt, no one could explain why. Now, astronomers have performed the first calculations that fully explain this phenomenon, with compelling evidence pointing to the Milky Way's envelopment in an off-kilter halo of dark matter.

Pulsars may make dark matter glow      (via sciencedaily.com)     Original source 

The central question in the ongoing hunt for dark matter is: what is it made of? One possible answer is that dark matter consists of particles known as axions. A team of astrophysicists has now shown that if dark matter consists of axions, it may reveal itself in the form of a subtle additional glow coming from pulsating stars.

The end of genes: Routine test reveals unique divergence in genetic code      (via sciencedaily.com)     Original source 

Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics. The genome of a protist has revealed a seemingly unique divergence in the DNA code signalling the end of a gene, suggesting the need for further research to better understand this group of diverse organisms.

Plants could worsen air pollution on a warming planet      (via sciencedaily.com)     Original source 

New research shows that plants such as oak and poplar trees will emit more of a compound called isoprene as global temperatures climb. Isoprene from plants represents the highest flux of hydrocarbons to the atmosphere after methane. Although isoprene isn’t inherently bad — it actually helps plants better tolerate insect pests and high temperatures — it can worsen air pollution by reacting with nitrogen oxides from automobiles and coal-fired power plants. The new publication can help us better understand, predict and potentially mitigate the effects of increased isoprene emission as the planet warms.

Scientists discover the highest energy gamma-rays ever from a pulsar      (via sciencedaily.com)     Original source 

Scientists have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy of visible light. This observation is hard to reconcile with the theory of the production of such pulsed gamma rays, as the international team reports.

Plot thickens in hunt for ninth planet      (via sciencedaily.com)     Original source 

A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity originally developed to understand the rotation of galaxies.

Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought      (via sciencedaily.com)     Original source 

For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aftermath of a catastrophe.

Understanding greenhouse gases in oil palm plantations      (via sciencedaily.com)     Original source 

The rapid spread of oil palm plantations and associated high use of fertilizer raises concerns about the emission of nitrous oxide, a powerful greenhouse gas. A new study shows that oil palms’ photosynthesis and their response to meteorological and soil conditions play an important but still widely unexplored role in the amount of nitrous oxide produced by oil palm plantations.
