Published Reptile roadkill reveals new threat to endangered lizard species
(via sciencedaily.com) Original source The chance sighting of a dead snake beside a sandy track in remote Western Australia, and the investigation of its stomach contents, has led researchers to record the first known instance of a spotted mulga snake consuming a pygmy spiny-tailed skink, raising concerns for a similar-looking, endangered lizard species.
Published Interstellar signal linked to aliens was actually just a truck
(via sciencedaily.com) Original source Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.
Published The role of machine learning and computer vision in Imageomics
(via sciencedaily.com) Original source A new field promises to usher in a new era of using machine learning and computer vision to tackle small and large-scale questions about the biology of organisms around the globe.
Published New technique may help scientists stave off coral reef collapse
(via sciencedaily.com) Original source Producing coral skeleton components in the easy-to-use soft-bodied sea anemone Nematostella creates a perfect lab system for studying, and eventually helping, corals threatened by a changing climate.
Published Vitamin A may play a central role in stem cell biology and wound repair
(via sciencedaily.com) Original source Retinoic acid, the active state of Vitamin A, appears to regulate how stem cells enter and exit a transient state central to their role in wound repair.
Published New study reveals insight into which animals are most vulnerable to extinction due to climate change
(via sciencedaily.com) Original source In a new study, researchers have used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results could help to identify species most at risk today from human-driven climate change.
Published Rock weathering and climate: Low-relief mountain ranges are largest carbon sinks
(via sciencedaily.com) Original source For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such stable temperatures, Earth appears to have a 'thermostat' that regulates the concentration of atmospheric carbon dioxide over geological timescales, influencing global temperatures. The erosion and weathering of rocks are important parts of this 'thermostat.'
Published How does a virus hijack insect sperm to control disease vectors and pests?
(via sciencedaily.com) Original source A widespread bacteria called Wolbachia and a virus that it carries can cause sterility in male insects by hijacking their sperm, preventing them from fertilizing eggs of females that do not have the same combination of bacteria and virus. A new study has uncovered how this microbial combination manipulates sperm, which could lead to refined techniques to control populations of agricultural pests and insects that carry diseases like Zika and dengue to humans.
Published Shape-shifting ultrasound stickers detect post-surgical complications
(via sciencedaily.com) Original source Gastrointestinal surgeries carry risk of fluid leaks, a potentially life-threatening complication. But no existing methods can reliably and non-invasively detect these leaks. To address this unmet need, researchers developed a tiny, soft, flexible sticker that changes in shape inside the body, enabling standard ultrasound tech to detect leaks for earlier detection and intervention. After the patient has recovered, the soft, tiny sticker simply dissolves away.
Published The Malaria parasite generates genetic diversity using an evolutionary 'copy-paste' tactic
(via sciencedaily.com) Original source All modern Plasmodium falciparum, the deadliest malaria parasite in humans, are descendants of one initial infection and so are very closely related, with relatively limited genetic differences. A long-standing mystery in the field has revolved around a very few locations in the P. falciparum genome where there are 'spikes' of mutations -- far more than anywhere else. Researchers have identified two genes in which these unusual mutation spikes result from DNA being copied and pasted from one gene to another.
Published Loss of nature costs more than previously estimated
(via sciencedaily.com) Original source Researchers propose that governments apply a new method for calculating the benefits that arise from conserving biodiversity and nature for future generations.
Published First atom-level structure of packaged viral genome reveals new properties, dynamics
(via sciencedaily.com) Original source A computational model of the more than 26 million atoms in a DNA-packed viral capsid expands our understanding of virus structure and DNA dynamics, insights that could provide new research avenues and drug targets researchers report.
Published Method rapidly verifies that a robot will avoid collisions
(via sciencedaily.com) Original source A new safety-check technique can prove with 100 percent accuracy that a planned robot motion will not result in a collision. The method can generate a proof in seconds and does so in a way that can be easily verified by a human.
Published Doctors can now watch spinal cord activity during surgery
(via sciencedaily.com) Original source Scientists can make high resolution images of the human spinal cord during surgery. The advancement could help bring real relief to millions suffering chronic back pain.
Published Pinging pipes could help to identify lead water lines without excavation
(via sciencedaily.com) Original source A recent study showed that it is possible to discern the composition of a buried pipe by striking an accessible portion of it and monitoring the sound waves that reach the surface. This method could help water utility companies verify the location of lead water lines without having to break ground.
Published Earth's earliest forest revealed in Somerset fossils
(via sciencedaily.com) Original source The oldest fossilized forest known on Earth -- dating from 390 million years ago -- has been found in the high sandstone cliffs along the Devon and Somerset coast of South West England.
Published Lost tombs and quarries rediscovered on British military base in Cyprus
(via sciencedaily.com) Original source Archaeologists rediscovers 46 sites at the Eastern Sovereign Base Area at Dhekelia, Cyprus. Archaeologists located sites from archive records, a number of which were thought to have been 'lost.' They uncovered evidence of quarries and tombs likely to span from the Bronze Age, Byzantine, Hellenistic and Roman periods.
Published Children surpass a year of HIV remission after treatment pause
(via sciencedaily.com) Original source Four children have remained free of detectable HIV for more than one year after their antiretroviral therapy (ART) was paused to see if they could achieve HIV remission, according to new research. The children, who acquired HIV before birth, were enrolled in a clinical trial in which an ART regimen was started within 48 hours of birth and then closely monitored for drug safety and HIV viral suppression. The outcomes reported today follow planned ART interruptions once the children met predefined virological and immunological criteria.
Published Cracking epigenetic inheritance: Biologists discovered the secrets of how gene traits are passed on
(via sciencedaily.com) Original source A research team has recently made a significant breakthrough in understanding how the DNA copying machine helps pass on epigenetic information to maintain gene traits at each cell division. Understanding how this coupled mechanism could lead to new treatments for cancer and other epigenetic diseases by targeting specific changes in gene activity.
Published Eight new deep-sea species of marine sponges discovered
(via sciencedaily.com) Original source Despite marine sponges being widespread on our planet, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study reveals the presence of new sponge species and new records in unexplored habitats such as underwater caves or mountains around the Balearic Islands.
