Mosquitoes sense infrared from body heat to help track humans down      (via sciencedaily.com)     Original source 

While a mosquito bite is often no more than a temporary bother, in many parts of the world it can be scary. One mosquito species, Aedes aegypti, spreads the viruses that cause over 100,000,000 cases of dengue, yellow fever, Zika and other diseases every year. Another, Anopheles gambiae, spreads the parasite that causes malaria. The World Health Organization estimates that malaria alone causes more than 400,000 deaths every year. Indeed, their capacity to transmit disease has earned mosquitoes the title of deadliest animal.

Life after (feigned) death      (via sciencedaily.com)     Original source 

A new study has revealed what animals do after they have feigned death in order to avoid being killed by a predator and what the context of this behavior is.

Fisheries research overestimates fish stocks      (via sciencedaily.com)     Original source 

The state of fish stocks in the world's ocean is worse than previously thought. While overfishing has long been blamed on fisheries policies that set catch limits higher than scientific recommendations, a new study reveals that even these scientific recommendations were often too optimistic. The result? Far more global fish stocks are overfished or have collapsed than we thought.

Creature the size of a dust grain found hiding in California's Mono Lake      (via sciencedaily.com)     Original source 

Mono Lake is a beautiful but harsh environment, its salty and arsenic-laced water home to brine shrimp, alkali flies and little else. Scientists recently discovered an unsuspected resident, however, a microscopic creature -- a choanoflagelatte -- that forms colonies that harbor their own unique bacterial microbiomes. The creature, part of the sister group to all animals, could shed light on the evolution of animals' intimate interactions with bacteria and the rise of multicellular life.

Human-wildlife overlap expected to increase across more than half of land on Earth by 2070      (via sciencedaily.com)     Original source 

Human-wildlife overlap could increase across about 57% of the global lands by 2070 and could lead to more conflict between people and animals. Understanding where the overlap is likely to occur -- and which animals are likely to interact with humans in specific areas -- will be crucial information for urban planners, conservationists and countries that have pledged international conservation commitments.

To kill mammoths in the Ice Age, people used planted pikes, not throwing spears, researchers say      (via sciencedaily.com)     Original source 

Archeologists say new findings might help resolve the debate about Clovis points and reshape how we think about what life was like roughly 13,000 years ago. After an extensive review of writings and artwork -- and an experiment with replica Clovis point spears -- a team of archaeologists says humans may have braced the butt of their weapons against the ground in a way that would impale a charging animal. The force would have driven the spear deeper into the predator's body, unleashing a more damaging blow than even the strongest prehistoric hunters would have been capable of by throwing or jabbing megafauna.

Chalk-based coating creates a cooling fabric      (via sciencedaily.com)     Original source 

In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath treated fabric by up to 8 degrees Fahrenheit.

A new pandemic could ride in on animals we eat, researchers warn      (via sciencedaily.com)     Original source 

Researchers warn the animals we eat could be the gateway for a pandemic in the form of antimicrobial resistance, unleashing a wave of deadly superbugs. The World Health Organization estimates that drug-resistant diseases could cause up to 10 million deaths each year by 2050.

Quenching the intense heat of a fusion plasma may require a well-placed liquid metal evaporator      (via sciencedaily.com)     Original source 

New fusion simulations of the inside of a tokamak reveal the ideal spot for a 'cave' with flowing liquid lithium is near the bottom by the center stack, as the evaporating metal particles should land in just the right spot to dissipate excess heat from the plasma.

The power of face time: Insights from zebra finch courtship      (via sciencedaily.com)     Original source 

A new study on songbirds sheds light on the power of social interaction to facilitate learning, insights that potentially apply to human development. Researchers discovered that zebra finches deprived of early social experiences could still form strong bonds with a partner later in life. Once placed into cohabitation with a male, females that had never heard a mating song before could quickly develop a preference for his melody.

New insights on how bird flu crosses the species barrier      (via sciencedaily.com)     Original source 

The avian influenza virus needs to mutate to cross the species barrier and to infect and replicate within mammalian cells. Scientists have now deciphered the structure of the avian influenza virus's polymerase when it interacts with a human protein essential for the virus to replicate within the cell. The structure of this replication complex provides important information about the mutations that avian influenza polymerase must undergo to adapt to mammals, including humans. These results can help scientists monitor the evolution and adaptability of bird flu strains, such as H5N1 or H7N9, towards infecting other species.
