Symbiotic and pathogenic fungi may use similar molecular tools to manipulate plants      (via sciencedaily.com)     Original source 

Symbiotic and pathogenic fungi that interact with plants are distantly related and don't share many genetic similarities. Comparing plant pathogenic fungi and plant symbiotic fungi, scientists at the Sainsbury Laboratory Cambridge University (SLCU) have discovered that these remote relatives are using a similar group of proteins to manipulate and live within plants.

Forest birds with short, round wings more sensitive to habitat fragmentation      (via sciencedaily.com)     Original source 

Tropical forest birds, which tend to have wings that are short and round relative to their body length and shape, are more sensitive to habitat fragmentation than the long-, slender-winged species common in temperate forests.

Astrophysicists confirm the faintest galaxy ever seen in the early universe      (via sciencedaily.com)     Original source 

After the Big Bang, the universe expanded and cooled sufficiently for hydrogen atoms to form. In the absence of light from the first stars and galaxies, the universe entered a period known as the cosmic dark ages. The first stars and galaxies appeared several hundred million years later and began burning away the hydrogen fog left over from the Big Bang, rendering the universe transparent, like it is today. Researchers have now confirmed the existence of a distant, faint galaxy typical of those whose light burned through the hydrogen atoms; the finding should help them understand how the cosmic dark ages ended.

Study identifies boat strikes as a growing cause of manatee deaths in Belize      (via sciencedaily.com)     Original source 

The endangered Antillean manatee faces a growing threat from boat strikes in Belize, according to a new study that raises concerns about the survival of what had been considered a relatively healthy population. Belize hosts a population of around 1,000 manatees. With the growth of tourism in recent decades, however, Belize has seen a substantial increase in boat traffic, making boat strikes an increasingly important cause of manatee deaths and injuries.

NIRISS instrument on Webb maps an ultra-hot Jupiter's atmosphere      (via sciencedaily.com)     Original source 

There's an intriguing exoplanet out there -- 400 light-years out there -- that is so tantalizing that astronomers have been studying it since its discovery in 2009. One orbit for WASP-18 b around its star that is slightly larger than our Sun takes just 23 hours. There is nothing like it in our Solar System. A new study about this exoplanet, an ultra-hot gas giant 10 times more massive than Jupiter.

Study leads to milestone advances in understanding lethal bronzing of palm trees      (via sciencedaily.com)     Original source 

Scientists have identified a key chemical associated with lethal bronzing (LB) infected palm trees. LB is a bacterial disease that kills more than 20 species of palm trees in the Southern United States and Caribbean and has been devastating the Florida green industries for nearly two decades.

Protecting large ocean areas doesn't curb fishing catches      (via sciencedaily.com)     Original source 

In the first-ever 'before and after' assessment of the impact of establishing Mexico's Revillagigedo National Park on the fishing industry, a team of US and Mexican researchers found that Mexico's industrial fishing sector did not incur economic losses five years after the park's creation despite a full ban in fishing activity within the MPA.

Plants can distinguish when touch starts and stops, study suggests      (via sciencedaily.com)     Original source 

Even without nerves, plants can sense when something touches them and when it lets go, a study has found. In a set of experiments, individual plant cells responded to the touch of a very fine glass rod by sending slow waves of calcium signals to other plant cells, and when that pressure was released, they sent much more rapid waves. While scientists have known that plants can respond to touch, this study shows that plant cells send different signals when touch is initiated and ended.

Saved from extinction, Southern California's Channel Island Foxes now face new threat to survival      (via sciencedaily.com)     Original source 

Starting in the 1990s, Island Fox populations began to dwindle due to an outbreak of canine distemper and an increase in attacks by golden eagles. Some islands saw their population drop to as low as 15 individuals, but conservation efforts by the Federal government restored numbers by 2017. A new study reveals a worrying decrease in genetic diversity within the species, signaling a new threat to the Channel Islands foxes' survival. The decrease in genetic diversity reduces the foxes' ability to adapt to future challenges, such as climate change and introduced pathogens, putting their survival at risk once again. Although the foxes have low genetic diversity, they possess diverse gut microbiomes that could help them cope with environmental changes.

Light conveyed by the signal transmitting molecule sucrose controls growth of plant roots      (via sciencedaily.com)     Original source 

Researchers shows how information about the quantity of absorbed light passes from the leaves to the roots. Photosynthetic sucrose not only supplies roots with carbohydrates but also acts as a signal transmitter for light-dependent root architecture.

Quest for alien signals in the heart of the Milky Way takes off      (via sciencedaily.com)     Original source 

A graduate student is spearheading an extraordinary scientific endeavor -- a groundbreaking mission to uncover periodic signals emanating from the core of the Milky Way called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS). Such repetitive patterns could be the key to unlocking the mysteries of extraterrestrial intelligence in our galaxy.

X-ray emissions from black hole jets vary unexpectedly, challenging leading model of particle acceleration      (via sciencedaily.com)     Original source 

Black hole jets are known to emit x-rays, but how they accelerate particles to this high-energy state is still a mystery. Surprising new findings appear to rule out a leading theory, opening the door to reimagining how particle acceleration works. One model of how jets generate x-rays expects the jets' x-ray emissions to remain stable over long time scales. However, the new paper found that the x-ray emissions of a statistically significant number of jets varied over just a few years.

Researchers successfully induce primate oocytes in the lab      (via sciencedaily.com)     Original source 

The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for researchers to control the differentiation of stem cells in the lab (in vitro). Of particular interest are oocytes, which are female germ cells that develop into eggs. Understanding their development could have far-ranging impacts, from infertility treatment to conservation of endangered species. A new study has successfully induced meiotic (dividing) oocytes from the embryonic stem cells of cynomolgus monkeys, which share many physiological traits with humans. By establishing a culture method for inducing the differentiation of meiotic oocytes, the researchers aimed to shed light on germ cell development in both humans and other primates.
