Published First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com) Original source The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published How a plant app helps identify the consequences of climate change
(via sciencedaily.com) Original source A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.
Published Ancient large kangaroo moved mainly on four legs, according to new research
(via sciencedaily.com) Original source A type of extinct kangaroo that lived during the Pleistocene around two and a half million to ten thousand years ago, known as the 'giant wallaby', was a poor hopper, a study has found.
Published Ancient dingo DNA shows modern dingoes share little ancestry with modern dog breeds
(via sciencedaily.com) Original source A study of ancient dingo DNA revealed that the distribution of modern dingoes across Australia, including those on K'gari (formerly Fraser Island), pre-dates European colonization and interventions like the dingo-proof fence.
Published Wastewater is a viable medium for growing lettuce in hydroponic systems
(via sciencedaily.com) Original source Urban agriculture has the potential to improve food security through local, efficient, and sustainable food production. Examples of urban food systems include hydroponics, where plants grow in a nutrient solution without soil, and aquaponics, which combines hydroponics with raising fish in tanks. A new study examines the use of aquaponics wastewater as a growth medium for lettuce in a hydroponic system. This practice can potentially create a circular ecosystem for organic waste recycling and food production.
Published Climate change drives tree species towards colder, wetter regions
(via sciencedaily.com) Original source Climate change is likely to drive tree species towards colder and wetter regions.
Published Mechanism of bio-inspired control of liquid flow
(via sciencedaily.com) Original source The more we discover about the natural world, the more we find that nature is the greatest engineer. Past research implied that liquids can only be transported in fixed direction on species with specific liquid communication properties and cannot switch the transport direction. Recently, researchers have shown that an African plant controls water movement in a previously unknown way -- and this could inspire breakthroughs in a range of technologies in fluid dynamics and nature-inspired materials, including applications that require multistep and repeated reactions, such as microassays, medical diagnosis and solar desalination etc.
Published Giant salamander-like creature was a top predator in the ice age before the dinosaurs
(via sciencedaily.com) Original source Meet Gaiasia jennyae, the swamp creature with a toilet seat-shaped head. It lived 40 million years before the first dinosaurs, and it was the top predator in its ecosystem.
Published Extinct humans survived on the Tibetan plateau for 160,000 years
(via sciencedaily.com) Original source Bone remains found in a Tibetan cave 3,280 m above sea level indicate an ancient group of humans survived here for many millennia.
Published Study illuminates cues algae use to 'listen' to their environment
(via sciencedaily.com) Original source New research shows how a small group of single-celled algae are able to use chemical cues to communicate stress information. Understanding this ability, once thought unique to plants, helps illuminate the complex evolutionary history of plants and algae.
Published Choose where to plant energy crops wisely to minimise loss of biodiversity
(via sciencedaily.com) Original source In the fight to protect biodiversity and limit climate change, the world will reap what it sows.
Published Sixty-million-year-old grape seeds reveal how the death of the dinosaurs may have paved the way for grapes to spread
(via sciencedaily.com) Original source Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
Published This desert moss has the potential to grow on Mars
(via sciencedaily.com) Original source The desert moss Syntrichia caninervis is a promising candidate for Mars colonization thanks to its extreme ability to tolerate harsh conditions lethal to most life forms. The moss is well known for its ability to tolerate drought conditions, but researchers now report that it can also survive freezing temperatures as low as 196 C, high levels of gamma radiation, and simulated Martian conditions involving these three stressors combined. In all cases, prior dehydration seemed to help the plants cope.
Published Ammonites' fate sealed by meteor strike that wiped out dinosaurs
(via sciencedaily.com) Original source Ammonites were not in decline before their extinction, scientists have found.
Published Groundbreaking discovery: Zinc can make crop yields more climate-resilient
(via sciencedaily.com) Original source Climate change, drought, increased temperature and other stressors challenge agricultural sustainability. Researchers have now made an unexpected discovery: zinc plays a pivotal role in the plant response to abiotic stress. This groundbreaking discovery not only sheds light on the intricate mechanisms of plant growth but also holds promise for revolutionizing crop resilience, especially in legume-based agriculture.
Published Prehistoric 'Pompeii' discovered: Most pristine trilobite fossils ever found shake up scientific understanding of the long extinct group
(via sciencedaily.com) Original source Researchers have described some of the best-preserved three-dimensional trilobite fossils ever discovered. The fossils, which are more than 500 million years old, were collected in the High Atlas of Morocco and are being referred to by scientists as 'Pompeii' trilobites due to their remarkable preservation in ash.
Published Why the harsh Snowball Earth kick-started our earliest multicellular ancestors
(via sciencedaily.com) Original source Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human society. A new article shows how specific physical conditions -- especially ocean viscosity and resource deprivation -- during the global glaciation period known as Snowball Earth could have driven eukaryotes to turn multicellular.
Published Scientists discover genetic 'off switch' in legume plants that limits biological ability to source nutrients
(via sciencedaily.com) Original source A genetic 'off switch' that shuts down the process in which legume plants convert atmospheric nitrogen into nutrients has been identified for the first time by a team of international scientists.
Published New tool enables faster, more cost-effective genome editing of traits to improve agriculture sustainability
(via sciencedaily.com) Original source New research had the goal of reducing the time and cost it takes to bring an improved crop to the marketplace to improve agriculture sustainability.
Published Almonds, pottery, wood help date famed Kyrenia shipwreck
(via sciencedaily.com) Original source Researchers have identified the likeliest timeline of the famous Hellenistic-era Kyrenia shipwreck, discovered and recovered off the north coast of Cyprus in the 1960s.
