Eye washing may ease hay fever ocular symptoms and improve quality of life

Hay fever, also known as allergic rhinitis, is the condition responsible for seasonal allergies or allergic reactions to other environmental allergens, like dust mites and animal dander. Estimates vary, but somewhere around 10–30% of the population worldwide experiences hay fever at least occasionally. Symptoms include nasal congestion, headaches, itchy throat and ocular symptoms, like itchy eyes, tearing and redness. Ultimately, these symptoms disrupt daily activities and affect quality of life for hay fever sufferers.

While many medications are available to reduce symptoms, many people prefer to include preventative measures. A new study from Japan, published in Scientific Reports, describes a large-scale survey of hay fever sufferers, comparing those who use eye washing as a preventative measure. The study reports that those using eyewash experience improved symptoms.

Data-driven surgical supply lists can reduce hospital costs and waste

Researchers at University of California San Diego School of Medicine, in collaboration with Data Science Alliance, a nonprofit promoting the importance of a responsible science environment, led a study showing that hospitals could save millions of dollars and significantly reduce surgical waste by rethinking supply lists used to prepare operating rooms, without compromising patient safety.

The study, published in the November 26, 2025, online edition of JAMA Surgery, found that preference cards— hospital checklists of tools and supplies for surgeries—often include far more items than are actually needed. Over time, as these lists are copied and reused, unnecessary items accumulate, creating inefficiencies and waste, resulting in operating rooms being stocked with supplies that often go unused.

“In addition to decreasing waste per surgery, optimized surgical preference cards can save significant hours in preparation and cleanup between cases,” said Sean Perez, MD, lead author and surgical resident at UC San Diego School of Medicine. “This means that we have more time to help more patients through life-changing and life-saving operations and procedures.”

Power-Hungry Data Centers Are Warming Homes in the Nordics

When Finnish engineer Ari Kurvi takes a hot shower or turns up the thermostat in his apartment, he’s tapping into waste heat generated by a 75-megawatt data center 5 kilometers away. As its computer servers churn through terabytes of digital information to support video calls, car navigation systems and web searches, an elaborate system of pipes and pumps harvests the cast-off energy and feeds it to homes in the town of Mantsala in southern Finland.

Since it began operation about a decade ago, the data center has provided heat for the town. Last year, it heated the equivalent of 2,500 homes, about two-thirds of Mantsala’s needs, cutting energy costs for residents and helping to blunt the environmental downsides associated with power-hungry computing infrastructure. Some of the world’s biggest tech companies are now embracing heat recovery from data centers in an effort to become more sustainable.

Kurvi is one of the pioneers of this emerging technology: As an engineer and project manager for Hewlett Packard starting in the 1980s, he spent years working with humming stacks of hardware in hot server rooms during the freezing Finnish winters. That made him think that there must be a good way to put that wasted heat to use.

By pairing computer processing facilities with district heating systems, countries like Finland and Sweden are trying to limit their environmental downsides.

Patrick Soon-Shiong: The Overlooked Immune Failure Driving Cancer Mortality

Lymphopenia represents a critical, widely unaddressed problem. Modern oncology regularly intervenes to reverse anemia or neutropenia, because decades of investment created drugs capable of restoring those cell populations. But when the lymphocyte compartment collapses, physicians have had no approved way to rebuild it. As a result, the most important immunologic marker in cancer care has remained largely unacted upon. The decline of the body’s cancer-killing lymphocytes has been observed, documented, and then largely ignored. Oncology is entering a new phase. The field is beginning to recognize that defeating cancer is not merely about targeting malignant cells; it is about ensuring that the immune system remains intact enough to participate in that fight…

…Once the lymphocyte compartment collapses, no drug can compensate.

The warning has been visible for decades, printed in plain text on every CBC panel run for every cancer patient in the country. If clinicians measure it, if regulators recognize it, and if the system supports restoring it, patient survival can change at scale.

Patrick Soon-Shiong, Chairman of Chan Soon-Shiong Family Foundation, Executive Chairman at ImmunityBio, and Executive Chairman of the Los Angeles Times, shared a post on X:

Every cancer patient undergoes a complete blood count. Within that routine report is a measurement that almost never makes its way into clinical conversations, yet it carries independent prognostic weight that often exceeds imaging, molecular markers, or tumor stage. That measurement is the absolute lymphocyte count, the readout of the circulating natural killer cells and T cells responsible for controlling malignant growth. When that number drops below 1,000 cells per microliter, the body enters a state of immune failure known as lymphopenia. In that state, the cellular machinery required to restrain cancer is no longer available.

Diamond quantum sensors improve spatial resolution of MRI

This accomplishment breaks the previous record of 48 qubits set by Jülich scientists in 2019 on Japan’s K computer. The new result highlights the extraordinary capabilities of JUPITER and provides a powerful testbed for exploring and validating quantum algorithms.

Simulating quantum computers is essential for advancing future quantum technologies. These simulations let researchers check experimental findings and experiment with new algorithmic approaches long before quantum hardware becomes advanced enough to run them directly. Key examples include the Variational Quantum Eigensolver (VQE), which can analyze molecules and materials, and the Quantum Approximate Optimization Algorithm (QAOA), used to improve decision-making in fields such as logistics, finance, and artificial intelligence.

Recreating a quantum computer on conventional systems is extremely demanding. As the number of qubits grows, the number of possible quantum states rises at an exponential rate. Each added qubit doubles the amount of computing power and memory required.

Although a typical laptop can still simulate around 30 qubits, reaching 50 qubits requires about 2 petabytes of memory, which is roughly two million gigabytes. ‘Only the world’s largest supercomputers currently offer that much,’ says Prof. Kristel Michielsen, Director at the Jülich Supercomputing Centre. ‘This use case illustrates how closely progress in high-performance computing and quantum research are intertwined today.’

The simulation replicates the intricate quantum physics of a real processor in full detail. Every operation – such as applying a quantum gate – affects more than 2 quadrillion complex numerical values, a ‘2’ with 15 zeros. These values must be synchronized across thousands of computing nodes in order to precisely replicate the functioning of a real quantum processor.

The JUPITER supercomputer set a new milestone by simulating 50 qubits. New memory and compression innovations made this breakthrough possible. A team from the Jülich Supercomputing Centre, working with NVIDIA specialists, has achieved a major milestone in quantum research. For the first time, they successfully simulated a universal quantum computer with 50 qubits, using JUPITER, Europe’s first exascale supercomputer, which began operation at Forschungszentrum Jülich in September.

Microquasars emerge as the Milky Way’s most extreme particle engines

LHAASO has traced the mysterious cosmic ray “knee” to powerful micro-quasars firing ultra-energetic particles across the galaxy. LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed long-held expectations. Precise cosmic-ray measurements reveal a new high-energy component, suggesting multiple sources within the Milky Way. These findings finally tie the “knee” structure to black hole jet systems.

Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have finally clarified a decades-old puzzle in astrophysics: the unusual drop in cosmic ray counts above 3 PeV that produces what scientists call the “knee” in the cosmic ray energy spectrum.

The cause of this steep decline has remained mysterious since it was first identified nearly 70 years ago. Researchers long suspected that the feature reflects the highest energies that cosmic ray sources can reach, marking a shift in the spectrum from one power-law behavior to another.
