Published A coral superhighway in the Indian Ocean
(via sciencedaily.com)
Original source 
Despite being scattered across more than a million square kilometers, new research has revealed that remote coral reefs across the Seychelles are closely related. Using genetic analyses and oceanographic modelling, researchers demonstrated for the first time that a network of ocean currents scatter significant numbers of larvae between these distant islands, acting as a 'coral superhighway.'
Published Scientists develop a rapid gene-editing screen to find effects of cancer mutations
(via sciencedaily.com)
Original source 
Researchers found a way to screen cancer-linked gene mutations much more easily and quickly than existing approaches, using a variant of CRISPR genome-editing known as prime editing.
Published Rainforest's next generation of trees threatened 30 years after logging
(via sciencedaily.com)
Original source 
Rainforest seedlings are more likely to survive in natural forests than in places where logging has happened -- even if tree restoration projects have taken place, new research shows.
Published Scientists propose new theory that explains sand ripples on Mars and on Earth
(via sciencedaily.com)
Original source 
Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on both planets?
Published New traffic signal would improve travel time for both pedestrians and vehicles
(via sciencedaily.com)
Original source 
Adding a fourth light to traffic signals -- in addition to red, green and yellow -- would shorten wait times at street corners for pedestrians, as well as improve traffic flow for both autonomous vehicles and human drivers. And the more autonomous vehicles there are in the traffic network, the shorter the wait times for everyone.
Published Climate policies to reduce motor vehicle emissions can improve children's health, save money
(via sciencedaily.com)
Original source 
A new study finds that policies to reduce carbon dioxide (CO2) emissions from motor vehicles combined with investments in electric vehicles and public transportation would reduce air pollution and bring large benefits to children's health. They would also save money.
Published Higher carnivorous dinosaur biodiversity of famous Kem Kem beds, Morocco
(via sciencedaily.com)
Original source 
An international team of palaeontologists applied recently developed methods to measure theropod (carnivorous) dinosaur species diversity. The newly applied method uses both traditional phylogenetic analysis, discriminant analysis as well as machine learning.
Published Range-shifting fishes are climate-change losers, according to new research
(via sciencedaily.com)
Original source 
Fish populations that experience rapid-range shift decline noticeably, up to 50 per cent over a decade. The populations affected most are those living on the northern poleward edges of their species' range. Researchers combined data from two large databases to examine the population numbers of range-shifting species. Their analysis revealed that extremely fast poleward shifting species, defined as upward of 17 kilometers per year, show marked declines in population, compared to negligible increases in populations that did not shift.
Published Pronghorn population declining due to human development
(via sciencedaily.com)
Original source 
A new article looked at 40 years of data collected on 40 pronghorn herds residing in the Wyoming Basin Shrub Steppe. Overall, 80% of the herds saw a decrease in productivity, and nearly 43% saw a significant decrease. After looking at a number of variables that could potentially contribute to the decline, the researchers identified the two most strongly associated: development of oil and gas resources and woody encroachment.
Published Ultrablack coating could make next-gen telescopes even better
(via sciencedaily.com)
Original source 
For telescopes operating in the vacuum of space, or optical equipment in extreme environments, existing coatings are often insufficient. Researchers have turned to atomic layer deposition and developed an ultrablack thin-film coating for aerospace-grade magnesium alloys. The team used alternating layers of aluminum-doped titanium carbide and silicon nitride and together the materials prevent nearly all light from reflecting off the coated surface. The coating absorbs 99.3% of light while being durable enough to survive in harsh conditions.
Published Gene flow in giraffes and what it means for their conservation
(via sciencedaily.com)
Original source 
Giraffes, with their bizarre body plan, have always held a special place in the minds of evolutionary biologists and non-experts alike. In a new study whole-genome sequencing data was used to investigate the evolutionary processes occurring within giraffes. In particular, the authors were interested in establishing whether different populations of giraffes really have been isolated from each other for extended periods of time, which is normally a requirement before new species can arise.
Published Powerful new tool ushers in new era of quantum materials research
(via sciencedaily.com)
Original source 
Research in quantum materials is paving the way for groundbreaking discoveries and is poised to drive technological advancements that will redefine the landscapes of industries like mining, energy, transportation, and medtech. A technique called time- and angle-resolved photoemission spectroscopy (TR-ARPES) has emerged as a powerful tool, allowing researchers to explore the equilibrium and dynamical properties of quantum materials via light-matter interaction.
Published Maternal obesity may promote liver cancer
(via sciencedaily.com)
Original source 
Obesity, which could reach 50% of the population in certain developed countries by 2030, is a major public health concern. It not only affects the health of those who suffer from it, but could also have serious consequences for their offspring. Scientists have studied the impact of maternal obesity on the risk of developing liver disease and liver cancer. Using an animal model, the team discovered that this risk was indeed much higher in the offspring of mothers suffering from obesity.
Published Cheetahs' unrivalled speed explained by their 'sweet spot' size, finds Imperial study
(via sciencedaily.com)
Original source 
A new study has answered a long-held question about why medium-sized land animals like cheetahs tend to be fastest.
Published India's water problems set to get worse as the world warms
(via sciencedaily.com)
Original source 
Winter storms known as western disturbances that provide crucial snow and rainfall to northern India are arriving significantly later in the year.
Published How do neural networks learn? A mathematical formula explains how they detect relevant patterns
(via sciencedaily.com)
Original source 
Neural networks have been powering breakthroughs in artificial intelligence, including the large language models that are now being used in a wide range of applications, from finance, to human resources to healthcare. But these networks remain a black box whose inner workings engineers and scientists struggle to understand. Now, a team has given neural networks the equivalent of an X-ray to uncover how they actually learn.
Published Mathematicians use AI to identify emerging COVID-19 variants
(via sciencedaily.com)
Original source 
Scientists have developed an AI framework that can identify and track new and concerning COVID-19 variants and could help with other infections in the future.
Published Cicadas' unique urination unlocks new understanding of fluid dynamics
(via sciencedaily.com)
Original source 
While most small insects and mammals urinate in droplets, cicadas urinate in jets. Researchers say the finding could be used to create better robots and small nozzles.
Published New research sets trap for potentially deadly sandfly
(via sciencedaily.com)
Original source 
Scientists have discovered the specific enzyme that a species of sandfly uses to produce a pheromone attractant, which could lead to the creation of targeted traps to control them and reduce the spread of the potentially fatal disease, Leishmaniasis.
Published Robotic interface masters a soft touch
(via sciencedaily.com)
Original source 
Researchers have developed a haptic device capable of reproducing the softness of various materials, from a marshmallow to a beating heart, overcoming a deceptively complex challenge that has previously eluded roboticists.
