Published 8 in 10 lizards could be at risk due to deforestation
(via sciencedaily.com)
Original source 
These reptiles move around tree trunks to seek warmth or shade. With trees disappearing, they would have trouble controlling their body temperature, a new study shows.
Published Plant Lavender, Marjoram and Ivy on your green wall to clean up the air
(via sciencedaily.com)
Original source 
Green walls can strip pollution from the air -- and some plants do it better than others, according to new research. Researchers planted 10 species on a custom-built 1.4m green wall.
Published Researchers invent new triple-junction tandem solar cells with world-record efficiency
(via sciencedaily.com)
Original source 
Scientists have developed a novel triple-junction perovskite/Si tandem solar cell that can achieve a certified world-record power conversion efficiency of 27.1 per cent across a solar energy absorption area of 1 sq cm, representing the best-performing triple-junction perovskite/Si tandem solar cell thus far. To achieve this, the team engineered a new cyanate-integrated perovskite solar cell that is stable and energy efficient.
Published Protecting joints from bacteria with mussels
(via sciencedaily.com)
Original source 
A collaborative team of researchers developed an implant coating triggering antibiotic release in response to bacterial infection.
Published JWST captures the end of planet formation
(via sciencedaily.com)
Original source 
The James Webb Space Telescope is helping scientists uncover how planets form by advancing understanding of their birthplaces and the circumstellar disks surrounding young stars. Scientists have imaged winds from an old planet-forming disk (still very young relative to the Sun) which is actively dispersing its gas content. Knowing when the gas disperses is important as it constrains the time left for nascent planets to consume the gas from their surroundings.
Published Less ice in the Arctic Ocean has complex effects on marine ecosystems and ocean productivity
(via sciencedaily.com)
Original source 
Most of the sunlight reaching the Arctic Ocean is reflected to space by sea ice, effectively shielding ocean ecosystems from sunlight. As the Arctic sea ice continues its downward trend, larger areas of the ocean become exposed to sunlight for longer periods, potentially allowing more primary production on the seafloor. However, according to a new study, this anticipated increase in primary production does not seem to be occurring uniformly across the Arctic Ocean.
Published Antarctica's coasts are becoming less icy
(via sciencedaily.com)
Original source 
Scientists found unexpected evidence the area of polynyas around Antarctica is increasing dramatically, and it follows an intriguing cycle, growing and shrinking roughly every 16 years.
Published New research shows migrating animals learn by experience
(via sciencedaily.com)
Original source 
Individual white storks incrementally straightened their migration routes to find more direct ways to move between destinations during the spring migration to summer breeding and nesting grounds, suggesting that experiential learning is an important part of successful migration.
Published An inside look at Beech tree disease
(via sciencedaily.com)
Original source 
A new study found differences at the cellular level of leaves from infected Beech trees -- variations that may account for tree mortality.
Published New AI model draws treasure maps to diagnose disease
(via sciencedaily.com)
Original source 
Researchers have developed an artificial intelligence model that can accurately identify tumors and diseases in medical images. The tool draws a map to explain each diagnosis, helping doctors follow its line of reasoning, check for accuracy, and explain the results to patients.
Published Scientists put forth a smarter way to protect a smarter grid
(via sciencedaily.com)
Original source 
Scientists have put forth a new approach to protect the electric grid, creating a tool that sorts and prioritizes cyber threats on the fly.
Published Modeling the origins of life: New evidence for an 'RNA World'
(via sciencedaily.com)
Original source 
Scientists provide fresh insights on the origins of life, presenting compelling evidence supporting the 'RNA World' hypothesis. The study unveils an RNA enzyme that can make accurate copies of other functional RNA strands, while also allowing new variants of the molecule to emerge over time. These remarkable capabilities suggest the earliest forms of evolution may have occurred on a molecular scale in RNA, and also bring scientists one step closer to re-creating autonomous RNA-based life in the laboratory.
Published An evolutionary mystery 125 million years in the making
(via sciencedaily.com)
Original source 
Plant biologists have uncovered an evolutionary mystery over 100 million years in the making. It turns out that sometime during the last 125 million years, tomatoes and Arabidopsis thaliana plants experienced an extreme genetic makeover. Just what happened remains unclear. But the mystery surrounds CLV3, a gene key to healthy plant growth and development.
Published 3D-printed skin closes wounds and contains hair follicle precursors
(via sciencedaily.com)
Original source 
Fat tissue holds the key to 3D printing layered living skin and potentially hair follicles, according to researchers who recently harnessed fat cells and supporting structures from clinically procured human tissue to precisely correct injuries in rats. The advancement could have implications for reconstructive facial surgery and even hair growth treatments for humans.
Published Webb unlocks secrets of one of the most distant galaxies ever seen
(via sciencedaily.com)
Original source 
Looking deeply into space and time, astronomers have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old.
Published Advances in forensic science improve accuracy of 'time of death' estimates
(via sciencedaily.com)
Original source 
Accurate 'time of death' estimates are a mainstay of murder mysteries and forensic programs, but such calculations in the real world are often complex and imprecise. In a first-of-its-kind study, researchers have discovered a group of common microbes that work together specifically to decompose flesh. These microorganisms serve as a biological clock and allow scientists to investigate the post-mortem breakdown of tissue with unprecedented precision.
Published The crow's best friend: Humans
(via sciencedaily.com)
Original source 
A new study has found that when humans are suddenly absent from the urban environment, the activity of the crows and ringneck parakeets that 'live' in the area reduces significantly. Conversely, the graceful prinias, who are generally considered shy, increased their activity.
Published Spontaneous curvature the key to shape-shifting nanomaterials
(via sciencedaily.com)
Original source 
Inspired by nature, nanotechnology researchers have identified 'spontaneous curvature' as the key factor determining how ultra-thin, artificial materials can transform into useful tubes, twists and helices.
Published Studies on coffee consumption: New biomarker proposed
(via sciencedaily.com)
Original source 
In order to record coffee consumption in nutrition and health studies, researchers usually rely on self-reporting by participants. However, this is not always reliable. It would therefore be desirable to conduct additional studies to objectively verify individual consumption using biomarkers. A research team has now validated the suitability of a specific roasted coffee compound and proposes it as a new, practical food biomarker.
Published Humans have driven the Earth's freshwater cycle out of its stable state
(via sciencedaily.com)
Original source 
New analysis shows that the global freshwater cycle has shifted far beyond pre-industrial conditions.
