UNIVERSITY PARK, Pa. — Children who are mistreated at a young age are more likely to experience a wide range of developmental delays and health problems, according to Christian Connell, Ken Young Family Professor in Healthy Children and professor of human development and family studies at Penn State. To combat these developmental problems, federal law requires that children under the age of three who are abused or neglected be evaluated for a developmental delay. Connell led a team of researchers who found that a child’s involvement with the Pennsylvania child welfare system (CWS) influenced how likely they were to be diagnosed with a developmental ...

New York City’s roads and bridges already incur millions in annual damage from oversized trucks, and a new study warns the shift to electric freight could intensify that burden. As electric trucks replace diesel models, their heavier batteries could increase the city's yearly repair costs by up to nearly 12 percent by 2050. Led by C2SMART researchers at NYU Tandon School of Engineering in collaboration with Rochester Institute of Technology (RIT) and published in Transport Policy, the study finds that oversized trucks already cause about $4.16 million in damage ...

Maternal stress during pregnancy profoundly affects fetal growth and long-term health. This comprehensive review synthesizes evidence showing that elevated cortisol, disrupted brain connectivity, and stress-induced inflammation can alter fetal brain structure, immune function, and developmental programming. The timing and type of stress exposure—ranging from natural disasters to chronic anxiety—determine specific outcomes such as preterm birth, low birth weight, and emotional dysregulation. These effects, often mediated through the hypothalamic–pituitary–adrenal (HPA) axis and epigenetic mechanisms, may extend ...

  Humanitarian organisations must go beyond reactive compliance to data protection laws if they are to continue using technology in a principled, safe, and trusted way in the digital age, experts have said. The sector must share knowledge and best practices for protecting the data of affected populations and shape the technologies it uses as they become central to the way aid is delivered around the world. In a new book, the experts highlight the risk of “scope creep”, where technologies initially created for emergency relief can be repurposed or used for other aims, potentially undermining ...

For many of us, climate change feels like a distant threat – damage that happens in the future somewhere far away to people we know little about. A new Stanford University-led study reveals how virtual reality can close that distance, enabling users to explore faraway places, develop a sense of attachment to those places, and care more about how a warming world is wreaking havoc on people’s lives. The findings, published this week in Scientific Reports, show that VR experiences significantly reduce people’s indifference to climate change-driven damages in faraway places compared to viewing static images. The findings demonstrate ...

In the summer of 1812, French emperor Napoleon Bonaparte led about half a million soldiers to invade the Russian Empire. But by December, only a fraction of the army remained alive. Historical records suggest that starvation, cold, and typhus led to their demise. In a new study publishing October 24 in the Cell Press journal Current Biology, a team of microbial paleogenomicists extracted DNA from the soldiers’ teeth and found no trace of typhus. Instead, they identified two pathogens known to cause enteric fever and relapsing fever—ailments which likely contributed to the army’s downfall.  “It’s very exciting to use a technology we have ...

Scientists from the Institut Pasteur have genetically analyzed the remains of former soldiers who retreated from Russia in 1812. They detected two pathogens, those responsible for paratyphoid fever and relapsing fever, which correlate with the symptoms described in historical accounts. The study was published as a preprint on bioRxiv on July 16, 2025. It will be published in the journal Current Biology on October 24. The famous Russian campaign led by Napoleon in 1812, also known as the "Patriotic War of 1812," ended with the retreat of the French army. Scientists from the Institut Pasteur's ...

In a paper [LINK WILL ACTIVATE WHEN EMBARGO LIFTS 11am ...

Advancing high-speed steady-state visually evoked potential (SSVEP)-based brain–computer interface (BCI) systems require effective electroencephalogram (EEG) decoding through deep learning. SSVEP-BCIs enable direct communication between the brain and external devices (e.g., spellers, prosthetics) by detecting EEG signals triggered by visual stimuli flickering at specific frequencies. They are prized for their high information transfer rate (ITR)—a key measure of BCI speed—and minimal training needs. “However, two critical barriers have hindered their performance: Data sparsity: Collecting ...

The competition is fierce. Olympic gymnast Simone Biles is pushing herself to perform stronger and more consistently. Then, her coach calls her “fat.” It’s meant as a motivation, but this time, it has the opposite effect. While some coaches might believe such comments could spur an athlete to train harder, new research involving the Binghamton University School of Management found a better way to boost an athlete’s mental toughness: transformational leadership techniques focusing on self-determination. These techniques have ...

T cells play central roles in the adaptive immune response against cancer. Their functional inactivation is a primary driver of tumor progression, making the reactivation of T cell function a main goal in immunotherapy. The review details how T cells specifically recognize and eliminate malignant cells by engaging tumor antigen peptides presented by MHC molecules. “T cells can specifically recognize tumor antigen epitopes presented by MHC molecules to clear malignant tumor cells. The targets that can be recognized by T cells in tumors mainly include two types”, the authors point out. Highly immunogenic, tumor-specific "neoantigens" derived from somatic ...

Rising seas are irreversible on human time scales and among the most severe consequences of climate change. Emissions released in the coming decades will determine how much coastlines are reshaped for centuries to come. New research shows that near-term mitigation could spare future generations around 0.6 meters of sea-level rise that would be caused by emissions between 2020 and 2090 following current policies, making today’s decisions critical not only for limiting warming but also for coastal ...

Findings from Mass General Brigham investigators highlight the intricate interplay of diverse physiological processes as the brain shifts from wakefulness to sleep A new study by investigators from Mass General Brigham used next-generation imaging technology to discover that when the brain is falling asleep, it shows a coordinated shift in activity. They found that during NREM (non-rapid eye movement) sleep, parts of the brain that handle movement and sensory input stay active and keep using energy, while ...

In the battle against mosquito-borne diseases that kill hundreds of thousands of people each year, scientists turned to an unlikely ally: a fungus that smells like flowers. Taking advantage of the mosquito’s natural attraction to flowers, an international team of researchers engineered a new strain of Metarhizium fungus that imitates a flower’s sweet scent and lures the bloodsucking bugs to their deaths.  Inspired by certain fungi that the team found emit a sweet-smelling chemical called longifolene to draw ...

Researchers have achieved a breakthrough in solar physics by providing the first direct evidence of small-scale torsional Alfvén waves in the Sun's corona – elusive magnetic waves that scientists have been searching for since the 1940s. The discovery, published today in Nature Astronomy, was made using unprecedented observations from the world's most powerful solar telescope, the U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope in Hawaii. The findings could finally explain one of the Sun's greatest mysteries ...

Winter vomiting disease is caused by the Norovirus, which is most virulent during the colder half of the year. The infection clears up after a couple of days, but the protection it provides is short-lived, meaning that the same person can fall repeatedly sick in a short space of time. But some people cannot succumb to the virus, thanks to a particular gene variant. “We wanted to trace the historical spread of the gene variant,” says Hugo Zeberg, senior lecturer in genetics at the Department of Physiology and Pharmacology, Karolinska Institutet, and researcher at the Max Planck Institute for Evolutionary Anthropology in Leipzig.   Defective gene protects against ...

New research finds that common nervous system components are present in the gastrointestinal tract where they influence tumour growth, revealing untapped opportunities for cancer treatment. GLOBAL: Australian researchers have identified two nervous system components that drive tumour growth in gastrointestinal cancers, creating promising new avenues for treatment with existing approved therapies.   Our gut contains its very own nervous system and is commonly regarded as the second brain. Key players of this system are neuropeptides, the signalling ...
