Published Milk to the rescue for diabetics? Cow produces human insulin in milk



An unassuming brown bovine from the south of Brazil has made history as the first transgenic cow capable of producing human insulin in her milk. The advancement could herald a new era in insulin production, one day eliminating drug scarcity and high costs for people living with diabetes.
Published New high-performance solar cell material



A new study reports the discovery of an entirely new stable, earth-abundant, high-performance material for solar absorbers -- the central part of a solar cell that turns light into electricity. While identifying new solar materials is typically very time-consuming, the researchers used a unique high-throughput computational screening method to quickly evaluate around 40,000 candidate materials.
Published A simple and robust experimental process for protein engineering



A protein engineering method using simple, cost-effective experiments and machine learning models can predict which proteins will be effective for a given purpose, according to a new study.
Published Who knew that coprophagy was so vital for birds' survival?



New research explains how eating feces (known as coprophagy) shapes wild birds' digestive tracts (gut biota), enabling them to absorb lost or deficient nutrients and adjust to seasonal variations in food sources.
Published Scientists find weak points on Epstein-Barr virus



Studies of interactions between two lab-generated monoclonal antibodies (mAbs) and an essential Epstein-Barr virus (EBV) protein have uncovered targets that could be exploited in designing treatments and vaccines for this extremely common virus.
Published Have metalenses expanded their reach into the ultraviolet region?



A team achieves successful mass production of metalenses designed for application in the ultraviolet region.
Published How a natural compound from sea squirts combats cancer



Trabectedin, a promising drug derived from the sea squirt Ecteinascidia turbinata, has shown potential in combating cancers resistant to conventional treatments. However, its precise mechanism of action has remained elusive -- until now.
Published New traffic signal would improve travel time for both pedestrians and vehicles



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 Powerful new tool ushers in new era of quantum materials research



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



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 Would the highly sensitive transparent ultrasound transducer revolutionize biomedical imaging technology?



A team develops an ultrasensitive broadband transparent ultrasound transducer.
Published Researchers uncover protein responsible for cold sensation



Researchers have identified the protein that enables mammals to sense cold, filling a long-standing knowledge gap in the field of sensory biology.
Published Flexible artificial intelligence optoelectronic sensors towards health monitoring



Artificial intelligence (AI) is known for its high energy consumption, especially in data-intensive tasks like health monitoring. To address this, researchers have developed a flexible paper-based sensor composed of nanocellulose and zinc oxide (ZnO) nanoparticles that operates like the human eyes and brain. The sensor is energy-efficient, responds to optical input in real-time, and is both flexible and easy to dispose of, making it ideal for health monitoring applications.
Published Wearable tech captures real-time hemodynamics on the go



Researchers have developed a photoacoustic imaging watch for high-resolution imaging of blood vessels in the skin. The wearable device could offer a non-invasive way to monitor hemodynamic indicators such as heart rate, blood pressure and oxygen saturation that can indicate how well a person's heart is working.
Published 'Molecular Rosetta Stone' reveals how our microbiome talks to us



Researchers have uncovered thousands of previously unknown bile acids, a type of molecule used by our gut microbiome to communicate with the rest of the body.
Published Higher bacterial counts detected in single-serving milks, researchers report



Scientists have detected higher bacterial counts in commercial, paperboard single-serving containers two weeks after processing than milk packaged in larger containers from the same facilities.
Published Combined microscopy technique catches light-driven polymers in the act



Researchers have used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.
Published New study discovers how altered protein folding drives multicellular evolution



Researchers have discovered a mechanism steering the evolution of multicellular life. They identified how altered protein folding drives multicellular evolution.
Published Tiny wireless light bulbs for biomedical applications



The combination of OLEDs and acoustic antennas creates a light source that could be used for minimally invasive treatment methods.
Published Researchers develop artificial building blocks of life



For the first time, scientists have developed artificial nucleotides, the building blocks of DNA, with several additional properties in the laboratory.
