Regrowing tooth enamel: Scientists discover breakthrough gel for stronger teeth and cavity prevention

A groundbreaking study reveals a new glycerol-stabilised calcium phosphate gel that can naturally repair early enamel damage, mimicking the tooth’s own mineralisation. This innovation promises a shift from drilling and filling cavities to regenerating enamel, potentially reducing sensitivity and offering long-lasting protection. While human trials are pending, this discovery heralds a future of regenerative dentistry.

Pressure to publish is rising as research time shrinks, finds survey of scientists

About 68% of respondents said the pressure to publish their research is greater than it was two to three years ago and only 45% agreed that they have sufficient time for research (see ‘Researchers are feeling the pressure’). Another concern is uncertainty over funding — just 33% of respondents expect funding in their field to grow in the next 2–3 years. And that proportion fell to just 11% in North America, reflecting unprecedented cuts to US research funding this year.

“As a researcher based in Brazil, I strongly relate to the survey’s findings, particularly the growing pressure to publish despite limited time and resources,” says Claudia Suemoto, a gerontologist at the University of São Paulo Medical School. “The demand for productivity has indeed increased in recent years, yet opportunities for funding and access to qualified personnel remain constrained in Brazil and other low-and middle-income countries.”

Suemoto says this imbalance of high demands and restricted resources often forces researchers to do more with less, which could affect the quality and innovation of research. Comments researchers made as part of the survey indicate that the lack of time is down to factors including growing administrative and teaching demands and trying to identity and acquire funding.

A breakthrough map reveals how the brain really works

Scientists have shown that brain connectivity patterns can predict mental functions across the entire brain. Each region has a unique “connectivity fingerprint” tied to its role in cognition, from language to memory. The strongest links were found in higher-level thinking skills that take years to develop. This work lays the groundwork for comparing healthy and disordered brains.

Plasma lens can focus attosecond pulses across different ranges of XUV light

A team of researchers from the Max Born Institute (MBI) in Berlin and DESY in Hamburg has demonstrated a plasma lens capable of focusing attosecond pulses. This breakthrough substantially increases the attosecond power available for experiments, opening up new opportunities for studying ultrafast electron dynamics. The results have now been published in Nature Photonics.

Attosecond pulses—bursts of light lasting only billionths of a billionth of a second—are essential tools for observing and controlling electronic motion in atoms, molecules, and solids. However, focusing these pulses, which lie in the extreme-ultraviolet (XUV) or X-ray region of the electromagnetic spectrum, has proven highly challenging due to the lack of suitable optics.

Mirrors are commonly used, but they offer low reflectivity and degrade quickly. Lenses, though the most straightforward tool for focusing , are not suitable for focusing attosecond pulses, because they absorb the XUV light and stretch the attosecond pulses in time.

Infrared sensors gain sensitivity with ultra-thin lens for fire and threat monitoring

Researchers have developed a highly sensitive method for detecting hotspots in the environment, such as bushfires or military threats, by harnessing the focusing power of meta-optical systems.

The key to the approach is innovative lens technology thinner than a , which can collect and process from fires and other heat sources with much improved efficiency. Crucially, it does not need cryogenic cooling, unlike current sensors.

The result is that promises to enhance devices in both the civilian and military spheres, said Dr. Tuomas Haggren, lead researcher on the project.

PEGATRON Chooses Georgetown, Texas for First U.S. Manufacturing Facility

PEGATRON’s arrival marks a turning point not only for Georgetown, but for the broader Central Texas innovation corridor. The Taiwan-based technology giant, known for designing and manufacturing everything from laptops to automotive electronics, already plays a quiet but massive role in powering many of the world’s best-known tech brands.

According to PEGATRON Corporation, their focus on smart manufacturing and artificial intelligence solutions has made them one of the world’s top players in electronics and computing systems.

When Hello Georgetown first reported PEGATRON’s interest in a U.S. facility earlier this year, the discussion centered on shifting global supply chains and the growing desire to bring advanced production closer to U.S. customers. That conversation has now become reality.

Neural implant smaller than a grain of salt can wirelessly track brain

Cornell University researchers and collaborators have developed a neural implant so small that it can rest on a grain of salt, yet it can wirelessly transmit brain activity data in a living animal for more than a year.

The breakthrough, detailed Nov. 3 in Nature Electronics, demonstrates that microelectronic systems can function at an unprecedentedly small scale, opening new possibilities for neural monitoring, bio-integrated sensing and other applications.

Development of the device, called a microscale optoelectronic tetherless electrode, or MOTE, was co-led by Alyosha Molnar, professor in the school of electrical and , and Sunwoo Lee, an assistant professor at Nanyang Technological University who first began working on the technology as a postdoctoral associate in Molnar’s lab.

New Artificial Neurons Physically Replicate the Brain

A breakthrough in neuromorphic computing could lower the energy consumption of chips and accelerate progress toward artificial general intelligence (AGI). Researchers from the USC Viterbi School of Engineering and the School of Advanced Computing have created artificial neurons that closely mimic

Innovative Treatment Regrows 90% of Lost Hair

Hair loss affects millions of people worldwide. Although treatments do exist, these solutions are costly and not always effective. Looking for a more lasting and effective solution, scientists have turned their attention to understanding the molecular mechanisms that regulate hair growth, leading to a new frontier in hair regeneration: dermal exosomes.
