Published Photosynthesis 'hack' could lead to new ways of generating renewable energy
(via sciencedaily.com) 
Researchers have 'hacked' the earliest stages of photosynthesis, the natural machine that powers the vast majority of life on Earth, and discovered new ways to extract energy from the process, a finding that could lead to new ways of generating clean fuel and renewable energy.
Published Next epidemic could be spotted early in wastewater
(via sciencedaily.com)
Original source 
Researchers behind the UK's first pilot public health surveillance system based on analysis of wastewater say that routine monitoring at sewage treatment works could provide a powerful early warning system for the next flu or norovirus epidemic, alerting hospitals to prepare and providing public health agencies with vital health information.
Published Observing group-living animals with drones and computer vision
(via sciencedaily.com) 
New method to study the movement, behaviour, and environmental context of group-living animals using drones and computer vision.
Published New mosquito species reported in Florida
(via sciencedaily.com) 
A mosquito known only by its scientific name, Culex lactator, is the latest to establish in the Sunshine State, according to a new study.
Published Turn off porch light to aid caterpillars -- and safeguard backyard ecosystems
(via sciencedaily.com) 
Moderate levels of artificial light at night -- like the fixture illuminating your backyard -- bring more caterpillar predators and reduce the chance that these lepidoptera larvae grow up to become moths and serve as food for larger prey.
Published Researchers get to the 'bottom' of how beetles use their butts to stay hydrated
(via sciencedaily.com) 
Beetles are champions at surviving in extremely dry environments. In part, this property is due to their ability to suck water from the air with their rear ends. A new study explains just how. Beyond helping to explain how beetles thrive in environments where few other animals can survive, the knowledge could eventually be used for more targeted and delicate control of global pests such as the grain weevil and red flour beetle.
Published To ward off aging, stem cells must take out the trash
(via sciencedaily.com) 
Researchers find stem cells use a surprising system for discarding misfolded proteins. This unique pathway could be the key to maintaining long-term health and preventing age-related blood and immune disorders.
Published How the 'marsupial sabertooth' thylacosmilus saw its world
(via sciencedaily.com) 
A new study investigates how an extinct, carnivorous marsupial relative with canines so large they extended across the top of its skull could hunt effectively despite having wide-set eyes, like a cow or a horse. The skulls of carnivores typically have forward-facing eye sockets, or orbits, which helps enable stereoscopic (3D) vision, a useful adaptation for judging the position of prey before pouncing. Scientists studied whether the 'marsupial sabertooth' Thylacosmilus atrox could see in 3D at all.
Published Forest growing season in eastern U.S. has increased by a month
(via sciencedaily.com) 
The growing period of hardwood forests in eastern North America has increased by an average of one month over the past century as temperatures have steadily risen, a new study has found.
Published Fossil site is 'Rosetta Stone' for understanding early life
(via sciencedaily.com) 
Leading edge technology has uncovered secrets about a world-renowned fossil hoard that could offer vital clues about early life on Earth. Researchers who analyzed the 400 million-year-old cache, found in rural north-east Scotland, say their findings reveal better preservation of the fossils at a molecular level than was previously anticipated.
Published Indigenous Ashaninka DNA helps geneticists write new chapters of pre-colonial history in South America
(via sciencedaily.com) 
Geneticists have written new chapters in the reconstruction of pre-colonial Americas history after using DNA from the indigenous Ashaninka people from Amazonian Peru. They have discovered previously unexpected levels of genetic variation in this group and uncovered a strong hint that these people were involved in a South-to-North migration that led to the transition from an archaic to ceramic culture in the Caribbean islands.
Published Paleontologists flip the script on anemone fossils
(via sciencedaily.com) 
Billions of sea anemones adorn the bottom of the Earth's oceans -- yet they are among the rarest of fossils because their squishy bodies lack easily fossilized hard parts. Now a team of paleontologists has discovered that countless sea anemone fossils have been hiding in plain sight for nearly 50 years. It turns out that fossils long-interpreted as jellyfish were anemones. To do so, a team of scientists has simply turned the ancient animals upside down.
Published Jurassic shark: Shark from the Jurassic period was already highly evolved
(via sciencedaily.com) 
Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed. Evidence for this thesis has been provided by new fossils of a ray-like shark, Protospinax annectans, which demonstrate that sharks were already highly evolved in the Late Jurassic.
Published Ancient proteins offer new clues about origin of life on Earth
(via sciencedaily.com)
Original source 
By simulating early Earth conditions in the lab, researchers have found that without specific amino acids, ancient proteins would not have known how to evolve into everything alive on the planet today -- including plants, animals, and humans.
Published Clues about the Northeast's past and future climate from plant fossils
(via sciencedaily.com) 
A team of researchers is working to understand the details of the climate for the eastern portion of the United States from the Miocene, which unfortunately is a blank spot on paleo-climate maps. New findings suggest the future climate will be very close to the warmer, wetter, and more homogeneous climate similar to conditions experienced 5 million years ago.
Published Insect bite marks show first fossil evidence for plants' leaves folding up at night
(via sciencedaily.com) 
Plants can move in ways that might surprise you. Some of them even show 'sleep movements,' folding or raising their leaves each night before opening them again the next day. Now, researchers offer convincing evidence for these nightly movements, also known as foliar nyctinasty, in fossil plants that lived more than 250 million years ago.
Published Early Cretaceous shift in the global carbon cycle affected both land and sea
(via sciencedaily.com) 
Geologists doing fieldwork in southeastern Utah's Cedar Mountain Formation found carbon isotope evidence that the site, though on land, experienced the same early Cretaceous carbon-cycle change recorded in marine sedimentary rocks in Europe. This ancient carbon-cycle phenomenon, known as the 'Weissert Event' was driven by large, sustained volcanic eruptions in the Southern Hemisphere that greatly increased carbon dioxide levels in the atmosphere and produced significant greenhouse climate effects over a prolonged time.
Published Researchers solve a 150-year-old mystery: Aetosaur find involves juveniles
(via sciencedaily.com) 
Aetosaurs had a small head and a crocodile-like body. The land dwellers were up to six meters long and widely distributed geographically. They died out about 204 million years ago, at the end of the Triassic. In Germany, an assemblage of 24 Aetosaurus ferratus individuals, only between 20 and 82 centimeters long, was discovered in 1877. Since then, scientists have been puzzling over whether they were juveniles or small adults. A team has now solved the mystery: Bone examination of two specimens shows that they are juveniles.
Published Fossil discovery reveals complex ecosystems existed on Earth much earlier than previously thought
(via sciencedaily.com)
Original source 
About 250 million years ago, the Permian-Triassic mass extinction killed over 80 per cent of the planet's species. In the aftermath, scientists believe that life on earth was dominated by simple species for up to 10 million years before more complex ecosystems could evolve. Now this longstanding theory is being challenged by a team of international researchers.
Published A fossil fruit from California shows ancestors of coffee and potatoes survived cataclysm that killed the dinosaurs
(via sciencedaily.com)
Original source 
The discovery of an 80-million-year-old fossil plant pushes back the known origins of lamiids to the Cretaceous, extending the record of nearly 40,000 species of flowering plants including modern-day staple crops like coffee, tomatoes, potatoes and mint.
