How do birds flock? Researchers do the math to reveal previously unknown aerodynamic phenomenon      (via sciencedaily.com)     Original source 

How do birds fly in a coordinated and seemingly effortless fashion? Part of the answer lies in precise, and previously unknown, aerodynamic interactions, reports a team of mathematicians. Its breakthrough broadens our understanding of wildlife, including fish, who move in schools, and could have applications in transportation and energy.

Unveiling the lionfish invasion in the Mediterranean Sea      (via sciencedaily.com)     Original source 

Researchers have published a comprehensive study on the invasion of lionfish in the Mediterranean Sea, highlighting a rapid spread and the potential ecological impacts. The research shows the lionfish species Pterois miles has significantly expanded its territory in the Mediterranean since the invasion began around ten years ago. The invasive species has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.

Color variants in cuckoos: The advantages of rareness      (via sciencedaily.com)     Original source 

Every cuckoo is an adopted child -- raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of female cuckoos: a gray morph that looks like a sparrowhawk, and a rufous morph. Male cuckoos are always gray.

Eruption of mega-magnetic star lights up nearby galaxy      (via sciencedaily.com)     Original source 

While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays -- high-energy photons -- coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none. An international team realized that the burst must have been an extra-galactic flare from a magnetar, a young neutron star with an exceptionally strong magnetic field.

Squids' birthday influences mating      (via sciencedaily.com)     Original source 

The day a male spear squid hatches determines which mating tactic he will use throughout his life, according to new research. Spear squid (Heterololigo bleekeri) that hatch earlier in the season become 'consorts' which fight for mating opportunities. Those which hatch later become 'sneakers,' which use more clandestine mating tactics. Researchers found that the mating tactic determined by the birth date was fixed for the squid's whole life. Understanding how mating tactics are influenced by birth date, and the environmental conditions at that time, can help researchers consider how squid might be affected by climate change and the implications for marine resource management.

Study compares salmonella rates in backyard, commercial poultry farm samples      (via sciencedaily.com)     Original source 

Researchers find less Salmonella on backyard poultry farms. But concerns remain about the prevalance of multidrug-resistant bacteria on both large and small farms.

To find life in the universe, look to deadly Venus      (via sciencedaily.com)     Original source 

Despite surface temperatures hot enough to melt lead, lava-spewing volcanoes, and puffy clouds of sulfuric acid, uninhabitable Venus offers vital lessons about the potential for life on other planets, a new paper argues.

New compound from blessed thistle promotes functional nerve regeneration      (via sciencedaily.com)     Original source 

Blessed thistle (Cnicus benedictus) is a plant in the family Asteraceae. For centuries, it has been used as a medicinal herb as an extract or tea, e.g. to aid the digestive system. Researchers have now found a completely novel use for Cnicin. Animal models as well as human cells have shown that Cnicin significantly accelerates axon (nerve fibers) growth.

'Itinerant breeding' in East Coast shorebird species      (via sciencedaily.com)     Original source 

A study has found direct evidence of a species -- the American woodcock, a migratory shorebird from eastern and central North America -- that overlaps periods of migration and reproduction, a rare breeding strategy known as 'itinerant breeding.'

Lemur's lament: When one vulnerable species stalks another      (via sciencedaily.com)     Original source 

What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa.

Key protein regulates immune response to viruses in mammal cells      (via sciencedaily.com)     Original source 

Researchers have revealed the regulatory mechanism of a specific protein, TRBP, that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and nucleic acid medicines to treat genetic disorders.

Why can zebrafish regenerate damaged heart tissue, while other fish species cannot?      (via sciencedaily.com)     Original source 

A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light on how zebrafish heal heart tissue by comparing how this species responds to heart injury with medaka, a fish species that cannot regenerate cardiac tissue.

Fourteen years after the Gulf of Mexico oil spill, endemic fishes face an uncertain future      (via sciencedaily.com)     Original source 

The 2010 Gulf of Mexico Deepwater Horizon oil spill, the largest accidental spill in history, released almost 100 million gallons of oil, causing significant pollution. A decade later, its long-term effects remain unclear. A study investigating the impact on endemic fish species found 29 of 78 species unreported in museum collections since the spill, suggesting potential loss of biodiversity.
