Little-known microbes could help predict climate tipping points

02/06/2023
Rising temperatures could push ocean plankton and other single-celled creatures toward a carbon tipping point that fuels more warming. The carbon-eaters could become carbon-emitters. But new research shows it's also possible to detect early distress signals before they get there.

Ultrasound breaks new ground for forearm fractures in children

02/06/2023
Portable ultrasound devices could provide an alternative to x-ray machines for diagnosing forearm fractures in children in a move that could alleviate waiting times for families in hospital emergency departments (ED). Researchers compared functional outcomes in children given an ultrasound and those who received an x-ray on a suspected distal forearm fracture. The team treated 270 children, aged between five and 15 years, during the randomized trial, which included a check-up 28 days later and another check-in at eight weeks. The findings show the majority of children had similar recoveries and returned to full physical function.

Biodegradable plastic from sugar cane also threatens the environment

02/06/2023
Plastic made from cane sugar also threatens the environment. Researchers from the University of Gothenburg have found that perch change their behavior when exposed to so-called bioplastic.

Finally solved! The great mystery of quantized vortex motion

02/06/2023
Scientists investigated numerically the interaction between a quantized vortex and a normal-fluid. Based on the experimental results, researchers decided the most consistent of several theoretical models. They found that a model that accounts for changes in the normal-fluid and incorporates more theoretically accurate mutual friction is the most compatible with the experimental results.

Flat fullerene fragments attractive to electrons

02/06/2023
Researchers have gained new insights into the unique chemical properties of spherical molecules composed entirely of carbon atoms, called fullerenes. They did it by making flat fragments of the molecules, which surprisingly retained and even enhanced some key chemical properties.

Producing large, clean 2D materials made easy

02/06/2023
An international team of surface scientists has now developed a simple method to produce large and very clean 2D samples from a range of materials using three different substrates.

Researchers finds a way to reduce the overheating of semiconductor devices

02/06/2023
Scientists have identified a method for improving the thermal conductivity of thin metal films in semiconductors using surface waves for the first time in the world.

Petit-spot volcanoes involve the deepest known submarine hydrothermal activity, possibly release CO2 and methane

02/06/2023
Underwater volcanism and its hydrothermal activity play an important role in marine biogeochemical cycles, especially the carbon cycle. But the nature of hydrothermal activity at 'petit-spot' volcanoes have not been revealed at all. Now, scientists reveal that petit-spot hydrothermal activity occurs on the deepest seafloor known to date and could release carbon dioxide (CO2) and methane, which may have implications for the global carbon cycle.

New class of antibiotics to fight resistant bacteria

02/06/2023
Health professionals are in urgent need of new antibiotics to tackle resistant bacteria. Researchers have now modified the chemical structure of naturally occurring peptides to develop antimicrobial molecules that bind to novel targets in the bacteria's metabolism.

Multiple species of semi-aquatic dinosaur may have roamed pre-historic Britain

02/06/2023
Palaeontologists studying a British dinosaur tooth have concluded that several distinct groups of spinosaurs -- dinosaurs with fearsome crocodile-like skulls -- inhabited southern England over 100 million years ago.

Symbiotic and pathogenic fungi may use similar molecular tools to manipulate plants

02/06/2023
Symbiotic and pathogenic fungi that interact with plants are distantly related and don't share many genetic similarities. Comparing plant pathogenic fungi and plant symbiotic fungi, scientists at the Sainsbury Laboratory Cambridge University (SLCU) have discovered that these remote relatives are using a similar group of proteins to manipulate and live within plants.

DNA damage repaired by antioxidant enzymes

02/06/2023
In crisis, the nucleus calls antioxidant enzymes to the rescue. The nucleus being metabolically active is a profound paradigm shift with implications for cancer research.

Ticks prove resilient to extreme temperatures

02/06/2023
A recent study shows blacklegged ticks (Ixodes scapularis) are actually really good at surviving extreme cold and heat in nature. Previous lab research suggests that even short periods of especially warm or cold conditions should easily kill ticks, but the a new analysis reveals this is only the case for larval ticks in the environment.

Tiny video capsule shows promise as an alternative to endoscopy

02/06/2023
While ingestible video capsule endoscopes have been around for many years, the capsules have been limited by the fact that they could not be controlled by physicians. They moved passively, driven only by gravity and the natural movement of the body. Now, according to a new research study, physicians can remotely drive a miniature video capsule to all regions of the stomach to visualize and photograph potential problem areas. The new technology uses an external magnet and hand-held video game style joysticks to move the capsule in three-dimensions in the stomach. This new technology comes closer to the capabilities of a traditional tube-based endoscopy.

New method improves efficiency of 'vision transformer' AI systems

02/06/2023
Vision transformers (ViTs) are powerful artificial intelligence (AI) technologies that can identify or categorize objects in images -- however, there are significant challenges related to both computing power requirements and decision-making transparency. Researchers have now developed a new methodology that addresses both challenges, while also improving the ViT's ability to identify, classify and segment objects in images.

Forest protection and carbon dioxide stored in biomass

02/06/2023
A study has found that worldwide protected forests have an additional 9.65 billion metric tons of carbon stored in their above-ground biomass compared to ecologically similar unprotected areas.

PAINTing a wound-healing ink into cuts with a 3D-printing pen

02/06/2023
The body is pretty good at healing itself, though more severe wounds can require bandages or stitches. But researchers have now developed a wound-healing ink that can actively encourage the body to heal by exposing the cut to immune-system vesicles. The ink can be spread into a cut of any shape using a 3D-printing pen, and in mice, the technology nearly completely repaired wounds in just 12 days.

Reading between the cracks: Artificial intelligence can identify patterns in surface cracking to assess damage in reinforced concrete structures

02/06/2023
Researchers are trying to make the process more efficient and definitive by using artificial intelligence, combined with a classic mathematical method for quantifying web-like networks, to determine how damaged a concrete structure is, based solely on its pattern of cracking.

The 'breath' between atoms -- a new building block for quantum technology

02/06/2023
Researchers have discovered they can detect atomic 'breathing,' or the mechanical vibration between two layers of atoms, by observing the type of light those atoms emitted when stimulated by a laser. The sound of this atomic 'breath' could help researchers encode and transmit quantum information.

Quantifying mangroves' value as a climate solution and economic engine

02/06/2023
A new approach quantifies the value of mangrove forests in Belize for carbon sequestration, tourism, fisheries, and coastal protection, then uses the values to target conservation and restoration. The findings hold lessons for coastal countries looking for ways to balance climate goals under the Paris Agreement with economic development.
