Published Machine learning gives users 'superhuman' ability to open and control tools in virtual reality
(via sciencedaily.com)
Original source 
Researchers have developed a virtual reality application where a range of 3D modelling tools can be opened and controlled using just the movement of a user's hand.
Published Experiment shows biological interactions of microplastics in watery environment
(via sciencedaily.com)
Original source 
Scientists have learned over the years that when aquatic organisms such as zooplankton become exposed to microplastics, they eat poorly. Research now shows that their plastic-induced eating difficulties also limit the ability of zooplankton to control algal proliferation. When algae bloom out of control, this presents a problem because some species produce toxins. Also, algal blooms can be associated with pea-soupy, unattractive bodies of water and contribute to hypoxia, a low-oxygen condition that may lead to fish kills.
Published Video technology could transform how scientists monitor changes in species evolution and development
(via sciencedaily.com)
Original source 
New research combines microscope and video technology to analyze how different species develop, and how changes in the timings of any developments can be tracked. A detailed analysis of the Energy Proxy Traits (EPTs) that result from these processes has provided researchers with the first evidence that traditionally measured timings of developmental events are associated with far broader changes to the full set of an embryo's observable characteristics.
Published New algae species rewrites understanding of reef systems
(via sciencedaily.com)
Original source 
An international team of marine scientists has identified and officially named four species of algae new to science, challenging previous taxonomical assumptions within the Porolithon genus. The discovery has far-reaching implications for our understanding of the ecological role of these algae in the coral reef ecosystem.
Published Two fins are better than one: Fish synchronize tail fins to save energy
(via sciencedaily.com)
Original source 
They say two heads are better than one. But in the world of fish, it appears two fins are better than one. Researchers have produced a theoretical model that demonstrates the underlying mechanisms behind how fish will synchronize their fin movements to ride each other's vortices, thereby saving energy.
Published Brain implant may enable communication from thoughts alone
(via sciencedaily.com)
Original source 
A speech prosthetic developed by a collaborative team of neuroscientists, neurosurgeons and engineers can translate a person's brain signals into what they're trying to say. The new technology might one day help people unable to talk due to neurological disorders regain the ability to communicate through a brain-computer interface.
Published How salt from the Caribbean affects our climate
(via sciencedaily.com)
Original source 
Past cold periods such as the Little Ice Age were associated with reduced strength of North Atlantic currents and increased surface salinity in the Caribbean. This was accompanied by disturbances in the distribution of salt to the north leading to longer, stronger cooling phases in the northern hemisphere.
Published Photo battery achieves competitive voltage
(via sciencedaily.com)
Original source 
Researchers have developed a monolithically integrated photo battery using organic materials. The photo battery achieves an unprecedented high discharge potential of 3.6 volts. The system is capable of powering miniature devices.
Published Charged 'molecular beasts' the basis for new compounds
(via sciencedaily.com)
Original source 
Mass spectrometers are high-tech machines that play an important role in our society. They are highly sensitive analytical instruments that are indispensable in areas such as medical diagnostics, food quality control and the detection of hazardous chemical substances. A research group is working to modify mass spectrometers so that they can be used for a completely different purpose: the chemical synthesis of new molecules.
Published Predicting saltwater intrusion into groundwater using Plymouth, Mass. as test case
(via sciencedaily.com)
Original source 
As the world warms and ice sheets melt, the ocean continually rises. The greater Boston area can expect to see between one and six feet of sea level rise by 2100, according to recent estimates. To find out what this rise might mean for freshwater supplies, a team of hydrogeologists developed an innovative new model that can not only predict saltwater intrusion over the next 75 years, but also pinpoint the main sources of salt contamination today -- road salt and human development.
Published Visualizing fungal infections deep in living host tissue reveals proline metabolism facilitates virulence
(via sciencedaily.com)
Original source 
Scientists have published the first successful application of 2-photon intravital microscopy (IVM) to image the dynamics of fungal infections in the kidney of a living host. The study reveals that the opportunistic human fungal pathogen Candida albicans requires the ability to metabolize proline, an amino acid obtained from the host, to mount virulent infections.
Published Researchers develop solid-state thermal transistor for better heat management
(via sciencedaily.com)
Original source 
A team of researchers has unveiled a first-of-its-kind stable and fully solid-state thermal transistor that uses an electric field to control a semiconductor device's heat movement. The group's study details how the device works and its potential applications. With top speed and performance, the transistor could open new frontiers in heat management of computer chips through an atomic-level design and molecular engineering. The advance could also further the understanding of how heat is regulated in the human body.
Published New designs for solid-state electrolytes may soon revolutionize the battery industry

Researchers have announced a major breakthrough in the field of next-generation solid-state batteries. It is believed that their new findings will enable the creation of batteries based on a novel chloride-based solid electrolyte that exhibits exceptional ionic conductivity.
Published Making electric vehicles last
(via sciencedaily.com)
Original source 
In the realm of electric vehicles, powered by stored electric energy, the key lies in rechargeable batteries capable of enduring multiple charge cycles. Lithium-ion batteries have been the poster child for this application. However, due to limitations in energy storage capacity and other associated challenges, the focus has shifted to an intriguing alternative known as dual-ion batteries (DIBs).

Published Researchers discover new ultra strong material for microchip sensors
(via sciencedaily.com)
Original source 
Researchers have unveiled a remarkable new material with potential to impact the world of material science: amorphous silicon carbide (a-SiC). Beyond its exceptional strength, this material demonstrates mechanical properties crucial for vibration isolation on a microchip. Amorphous silicon carbide is therefore particularly suitable for making ultra-sensitive microchip sensors.
Published How a climate model can illustrate and explain ice-age climate variability
(via sciencedaily.com)
Original source 
During the last ice age, the last glacial maximum about 20,000 years ago, the climate in the North Atlantic underwent much greater multi-centennial variability than it does in the present warm period. This is supported by evidence found in ice and seafloor cores. Researchers have now shown, based on a climate model, that internal mechanisms such as temperature and salinity distribution in the ocean are driving this multi-centennial variability.
