One glass, full color: Sub-millimeter waveguide shrinks AR glasses
Augmented-reality (AR) technology is rapidly finding its way into everyday life, from education and healthcare to gaming and entertainment. However, the core AR device remains bulky and heavy, making prolonged wear uncomfortable. A breakthrough now promises to change that. A research team has slashed both thickness and weight using a single-layer waveguide.

All of the biggest U.S. cities are sinking
A new study of the 28 most populous U.S. cities finds that all are sinking to one degree or another. The cities include not just those on the coasts, where relative sea level is a concern, but many in the interior. Furthermore, using newly granular data, the study finds that some cities are sinking at different rates in different spots, or sinking in some places and rising in others, potentially introducing stresses that could affect buildings and other infrastructure.

Music therapy helps brain-injured children
Music could provide a breakthrough in assessing consciousness levels in children who have suffered significant brain injuries, according to new research.
Discovery opens up for new ways to treat chlamydia
Researchers have discovered a type of molecule that can kill chlamydia bacteria but spare bacteria that are important for health. The discovery opens the door for further research towards developing new antibiotics against chlamydia.
Promising Parkinson's drug decoded
How well our brain functions depends heavily on the performance of our nerve cells. That is why they are regularly checked for their proper function -- defective cell components are marked, disposed of and recycled. This includes the mitochondria, the powerhouses of our cells. Impaired quality control of mitochondria plays a central role in Parkinson's disease.
Just 30 species of tree dominate world's most diverse savanna
Scientists have found that a mere 30 species of trees in the Cerrado -- the world's largest and most floristically diverse savanna -- account for nearly half of all its trees. The 'hyperdominance' by a few species could help researchers understand how this vast ecosystem functions.
Evaluating the safety and efficacy of a smallpox vaccine for preventing mpox
The recent global monkeypox (mpox) outbreak, with a new and aggressive variant, has underscored the dire need for safe, broadly effective, and accessible vaccines. The LC16m8 vaccine, an attenuated vaccinia virus strain originally developed for smallpox, is a promising option for countering the mpox virus. Exploring this potential further, researchers employed a cross-species immunological analysis to provide new insights into LC16m8's immunogenicity and safety against mpox.

Biological age predicts cardiovascular disease morbidity and mortality
Looking at your biological age -- the level of deterioration in your body -- can give a clearer picture of your heart disease risk than traditional tools alone.
HIV drugs offer 'substantial' Alzheimer's protection, new research indicates
The drugs, called NRTIs, have the potential to prevent a million cases of Alzheimer's every year, the researchers believe.
Reactivity to tumor antigens is important for TIL therapy
A team of researchers has found new insight into why some lung cancer patients do not benefit from tumor-infiltrating lymphocyte, or TIL therapy. Their findings may help improve future ways to deliver this cellular immunotherapy for metastatic non-small cell lung cancer.
Engineering an antibody against flu with sticky staying power
Scientists have engineered a monoclonal antibody that can protect mice from a lethal dose of influenza A, a new study shows. The new molecule combines the specificity of a mature flu fighter with the broad binding capacity of a more general immune system defender.
AI-designed DNA controls genes in healthy mammalian cells for first time
A recent study marks the first reported instance of generative AI designing synthetic molecules that can successfully control gene expression in healthy mammalian cells. As a proof-of-concept, the authors of the study asked the AI to design synthetic fragments which activate a gene coding for a fluorescent protein in some cells while leaving gene expression patterns unaltered. They created the fragments from scratch and dropped them into mouse blood cells, where the sequence fused with the genome at random locations. The experiments worked exactly as predicted and pave the way for new strategies to give instructions to a cell and guide how they develop and behave with unprecedented accuracy.
Vitamin supplements slow down the progression of glaucoma
A vitamin supplement that improves metabolism in the eye appears to slow down damage to the optic nerve in glaucoma. The researchers behind the study have now started a clinical trial on patients.
Building vaccines for future versions of a virus
AI model EVE-Vax provides clues about how a virus may evolve and the immune response it could provoke.
Smart home devices used to monitor domestic workers raise safety concerns
The growing use of smart home devices is undermining the privacy and safety of domestic workers. New research reveals how surveillance technologies reinforce a sense of constant monitoring and control by domestic workers' employers, increasing their vulnerability and impacting their mental wellbeing.
Non-inherited genes affect children's development
Parents' genes -- even when not directly inherited by a child -- may play a role in their educational and mental health outcomes, finds a new report.
Enhanced CAR T cell therapy offers new strategy for lymphoma

Women diagnosed with breast cancer who carry particular BRCA1 and BRCA2 genetic variants are offered surgery to remove the ovaries and fallopian tubes as this dramatically reduces their risk of ovarian cancer. Now, researchers have shown that this procedure -- known as bilateral salpingo-oophorectomy (BSO) -- is associated with a substantial reduction in the risk of early death among these women, without any serious side-effects.
Social media platform tailoring could support more fulfilling use, study finds
Redesigning social media to suit different needs of users could make their time online more focused, according to new research.
Eating ultra processed foods may speed up early signs of Parkinson's disease
People who eat more ultra processed foods like cold breakfast cereal, cookies and hot dogs are more likely to have early signs of Parkinson's disease when compared to those who eat very few ultra processed foods, according to a new study. The study does not prove that eating more ultra processed foods causes early signs of Parkinson's disease; it only shows an association.
Sleep apnea during REM sleep linked to memory-related brain changes
Obstructive sleep apnea, a condition that causes lower oxygen levels during sleep, is linked to degeneration of brain regions associated with memory through damage to the brain's small blood vessels, according to a new study. The study found the brain changes were strongly associated with the severity of drops in oxygen levels during rapid eye movement (REM) sleep. The study does not prove that sleep apnea causes this degeneration; it only shows an association.
Vaccines of the future: Harnessing the immune system for long-lasting protection
Scientists have uncovered a promising new way to enhance the effectiveness of vaccines by tapping into the potential of a specific type of immune cell, opening the door to long-lasting vaccines for viruses and enhanced cancer therapies. The study used a novel approach combined with cutting-edge mRNA vaccine technology to increase the formation of a type of T cell which has remarkable self-renewing capacity and can remember threats for years and even decades.

Using a thermal sensor smaller than a grain of sand, engineers have measured the vibrations, or phonons, within individual molecules.
Researchers identify measure of pulse rate that can predict faster cognitive decline in older adults
Healthy hearts are adaptable, and heartbeats exhibit complex variation as they adjust to tiny changes in the body and environment. Researchers have applied a new way to measure the complexity of pulse rates, using data collected through wearable pulse oximetry devices. The new method provides a more detailed peek into heart health than traditional measures, uncovering a link between reduced complexity and future cognitive decline.
