Scientists detect and validate the longest-period exoplanet found with TESS      (via sciencedaily.com) 

Scientists have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which have orbital periods of 10-200 days and are at least six times Earth's radius. This recent discovery offers exciting research opportunities for the future of finding long-period planets that resemble those in our own solar system.

A global observatory to monitor Earth's biodiversity      (via sciencedaily.com)     Original source 

At a time of unparalleled rates of biodiversity loss, a new interconnected system to monitor biodiversity around the world is needed to guide action quickly enough to target conservation efforts to where they are most needed.

Unprecedented gamma-ray burst explained by long-lived jet      (via sciencedaily.com) 

While astrophysicists previously believed that only supernovae could generate long gamma-ray bursts (GRBs), a 2021 observation uncovered evidence that compact-object mergers also can generate the phenomenon. Now, a new simulation confirms and explains this finding. If the accretion disk around the black hole is massive, it launches a jet that lasts several seconds, matching the description of a long GRB from a merger.

Evolutionary imbalance explains global plant invasions      (via sciencedaily.com)     Original source 

Plant species from certain geographic regions are more successful in spreading outside their native ranges than others -- but why? Ecologists provide answers by exploring how the ecological and evolutionary histories of plants can influence their relationships with humans and their success as invaders.

Algae provide clues about 600 million years of plant evolution      (via sciencedaily.com)     Original source 

Researchers generated large scale gene expression data to investigate the molecular networks that operate in one of the closest algal relatives of land plants, a humble single-celled alga called Mesotaenium endlicherianum.

Telescopes help unravel pulsar puzzle      (via sciencedaily.com) 

With a remarkable observational campaign that involved 12 telescopes both on the ground and in space, including three European Southern Observatory (ESO) facilities, astronomers have uncovered the strange behavior of a pulsar, a super-fast-spinning dead star. This mysterious object is known to switch between two brightness modes almost constantly, something that until now has been an enigma. But astronomers have now found that sudden ejections of matter from the pulsar over very short periods are responsible for the peculiar switches.

Neptune's disappearing clouds linked to the solar cycle      (via sciencedaily.com) 

Astronomers have uncovered a link between Neptune's shifting cloud abundance and the 11-year solar cycle, in which the waxing and waning of the Sun's entangled magnetic fields drives solar activity.

Want to fight climate change? Don't poach gorillas (or elephants, hornbills, toucans, etc.)      (via sciencedaily.com)     Original source 

A new article found that overhunting of gorillas, elephants, and other large fruit-eating seed-dispersers make tropical forests less able to store or sequester carbon.

Male crested macaques more likely to respond to offspring screams recruiting support      (via sciencedaily.com)     Original source 

When infants are involved in agonistic conflicts, male crested macaques (Macaca nigra) are more likely to respond to screams from their own offspring. This is the conclusion of a recent study led by behavioral ecologists. The researchers studied the behavior of crested macaques in the Tangkoko Nature Reserve on Sulawesi, Indonesia, over a 24-month period (2008 to 2010).

Wastewater pipe dig reveals 'fossil treasure trove'      (via sciencedaily.com)     Original source 

A new article describes the 266 fossil species as one of the richest and most diverse groups of three-million-year-old fauna ever found in New Zealand. At least ten previously unknown species will be described and named in future research. Fossils of the world's oldest known flax snails, an extinct sawshark spine, and great white shark teeth have all been found in a mound of sand excavated from beneath Mangere Wastewater Treatment Plant in 2020.

How being in space impairs astronauts' immune system      (via sciencedaily.com)     Original source 

A new study has examined how T cells of the immune system are affected by weightlessness. The results could explain why astronauts' T cells become less active and less effective at fighting infection.

Mysterious Neptune dark spot detected from Earth for the first time      (via sciencedaily.com) 

Using ESO's Very Large Telescope (VLT), astronomers have observed a large dark spot in Neptune's atmosphere, with an unexpected smaller bright spot adjacent to it. This is the first time a dark spot on the planet has ever been observed with a telescope on Earth. These occasional features in the blue background of Neptune's atmosphere are a mystery to astronomers, and the new results provide further clues as to their nature and origin.

Fungi-eating plants and flies team up for reproduction      (via sciencedaily.com)     Original source 

Fungi-eating orchids were found for the first time to offer their flowers to fungi-eating fruit flies in exchange for pollination, which is the first evidence for nursery pollination in orchids. This unique new plant-animal relationship hints at an evolutionary transition towards mutualistic symbiosis.

Loss of Antarctic sea ice causes catastrophic breeding failure for emperor penguins      (via sciencedaily.com)     Original source 

Emperor penguin colonies experienced unprecedented breeding failure in a region of Antarctica where there was total sea ice loss in 2022. The discovery supports predictions that over 90% of emperor penguin colonies will be quasi-extinct by the end of the century, based on current global warming trends.

How a cup of water can unlock the secrets of our Universe      (via sciencedaily.com)     Original source 

A researcher made a discovery that could change our understanding of the universe. He reveals that there is a range in which fundamental constants can vary, allowing for the viscosity needed for life processes to occur within and between living cells. This is an important piece of the puzzle in determining where these constants come from and how they impact life as we know it.

Biodiversity protects against invasions of non-native tree species      (via sciencedaily.com) 

Researchers combined human and ecological factors to analyze the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.
