Researchers at the University of Oxford and their collaborators, including the Serum Institute of India, have developed an innovative method to identify falsified vaccines without opening the vaccine vial.
The new method, published in npj Vaccines, analyzes the vaccine vial label and its adhesive and therefore allows the vaccine vials to be retained in the supply chain. Furthermore, the study has shown that the technique can also differentiate genuine COVID-19 vaccine liquid from falsified vaccine surrogates, using a recently published method developed using non-COVID vaccines.
The World Health Organization (WHO) estimates that 10.5% of medicines worldwide in low and middle-income countries are substandard or are falsified medicines made by criminals. This threatens global health since the medicines and vaccines fail to prevent and treat the diseases for which they were intended, and they risk additional adverse health consequences if the ingredients used by criminals in the falsified products are harmful.
As their primary food source becomes less accessible, the bears enter longer fasting periods, leading to declining health and population numbers.
“A loss of sea ice means bears spend less time hunting seals and more time fasting on land,” said Louise Archer, a postdoctoral researcher and lead author of the study.
This prolonged fasting drains polar bears’ energy reserves, reducing their ability to reproduce and raise cubs. Without enough stored fat, female bears struggle to give birth and nurse their young. Over time, this energy deficit has led to a sharp population decline.
Health during pregnancy does not cause autism, according to a study of 1.1M pregnancies. Genetics and fetal complications play a much larger role, challenging long-held assumptions about autism risk factors. +.
Summary: A large study analyzing over 1.1 million pregnancies found no strong evidence that maternal health conditions during pregnancy cause autism. Instead, nearly all previously reported associations between maternal diagnoses and autism could be explained by genetic or environmental factors.
Researchers found that only fetal complications remained statistically linked to autism, suggesting these issues might be early signs rather than causes. By analyzing sibling and paternal health records, the study further ruled out many maternal conditions as contributing factors.
The findings emphasize that autism likely begins before birth due to genetic influences rather than maternal health conditions. This research may help alleviate guilt for parents and shift focus toward early diagnosis and support.
Summary: Scientists have used advanced X-ray phase-contrast tomography (XPCT) to uncover how gut health may influence Alzheimer’s disease. The study found structural changes in the gut of Alzheimer’s-affected mice, revealing abnormalities in intestinal cells, neurons, and mucus secretion.
This supports the hypothesis that harmful gut bacteria may escape into circulation, triggering brain inflammation and neurodegeneration. The findings highlight the gut-brain connection and provide a new tool for detecting early disease markers.
Researchers aim to further explore how the enteric nervous system communicates with the brain in Alzheimer’s. The study paves the way for potential new therapeutic targets based on gut health.
As the demand for digital security grows, researchers have developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate. This advance could pave the way for more secure communication channels, helping to protect sensitive data.
“From rapidly evolving digital currencies to governance, health care, communications and social networks, the demand for robust protection systems to combat digital fraud continues to grow,” said research team leader Stelios Tzortzakis from the Institute of Electronic Structure and Laser, Foundation for Research and Technology Hellas and the University of Crete, both in Greece.
“Our new system achieves an exceptional level of encryption by utilizing a neural network to generate the decryption key, which can only be created by the owner of the encryption system.”

QUT researchers are part of an international group who have explored ways in which organic transistors are being developed for use as wearable health sensors.
The currently available bioelectronic devices, such as pacemakers, that can be embedded with the human body are mostly based on rigid components.
However, the next-generation devices—which are researched and developed by bioelectronic engineers, organic chemists, and materials scientists—will use soft organic materials that allow comfortable wearability as well as efficient monitoring of health.
Check out this fascinating interview with Professor Bruce Hollis, a pioneer in vitamin D research and an expert on vitamin D deficiency.

Professor Hollis’ research has provided a new understanding of the importance of vitamin D and its full range of functions. Vitamin D has been understood as an essential nutrient for skeletal integrity and maintaining blood calcium levels. As microbiology and research developed, researchers found that many cells that had nothing to do with the skeleton could respond to vitamin D, including cancer and immune cells. Vitamin D exists in different forms inside the body. When you take a supplement or sunlight hits your skin, you’re dealing with the inactive form of vitamin D. It is then turned into a compound called 25-hydroxy vitamin D, the intermediate form of vitamin D that stays in the blood for weeks. This form is picked up in blood tests but isn’t easily accessible by the tissues that might need it. The final form of vitamin D is one of the most potent hormones, 125 di-hydroxy vitamin D. Vitamin D is converted into the active form in the kidney but can also be converted inside the cells. The vast majority of studies substantiating our information on vitamin D in the U.S. have several problems and have produced inaccurate results. There is also no agreed-upon range on “normal” vitamin D levels—or what levels are considered a vitamin D deficiency. Professor Hollis has conducted research and has seen significant results using vitamin D to prevent birth complications in women in Iran, in patients with low-grade prostate cancer, and in lactation. He also explains the importance of magnesium, a key cofactor for vitamin D metabolism. Professor Hollis wants people to understand that few physicians recommend or acknowledge the benefits of vitamin D because national organizations have yet to properly understand and recognize them.

Our psychological profiles provide clues to our future risk and severity of cognitive decline that may one day inform tailored prevention strategies, a new study suggests.
“The aim was to elucidate how various combinations of psychological characteristics are related to mental, cognitive and brain health,” explains University of Barcelona psychologist David Bartrés-Faz.
“To date, psychological risk and protective factors have been examined almost exclusively independently: this approach is limiting, as psychological characteristics do not exist in isolation.”
