A multicenter clinical trial found that implanting collagen tiles during brain surgery improved tumor control and lowered the risk of recurrence by 12.1% compared to current standard of care. Patients treated with tile-based radiation therapy (TBRT) had a median overall survival of 42.5 months, more than double the 17.6 months seen wit...
Researchers at the University of Chicago Medicine discovered a new phenomenon where high doses of radiation cause growth in existing metastatic tumors. The 'badscopal effect' is attributed to increased production of amphiregulin, which weakens the immune system and makes cancer cells more resistant.
A multicenter retrospective cohort study found that postoperative adjuvant radiotherapy improves overall survival in pN2 NSCLC patients, particularly with examined lymph nodes <10 and a lymph node ratio ≤0.2 or ≥0.53. These findings suggest that ELNs and LNR are valuable for identifying patients who may benefit from PORT.
Researchers used high-resolution micro-CT scans to reveal key features in Palaeospondylus fossils, placing it as an early ancestor of tetrapods. The study resolves long-standing evolutionary mysteries, including the lack of teeth and dermal bones in the fossil record.
Researchers have successfully observed the inner structure of photonic crystals, a key material for controlling light beams, using ptychography. This breakthrough enables the creation of microprocessors for optical computers without destroying the crystal.
A new facility at Diamond Light Source allows for long-term experiments (weeks to years) in parallel, detecting phase evolution and structural changes. This addresses the need for studying slow processes like material hydration and metal-organic framework stability.
An international team of researchers has synthesized a new form of magnesium carbide with unique atomic structure. The substance retains its structure after pressure and temperature reduction, making it a promising element for synthesizing other compounds.
Researchers create pulse picking technique to enable users to select individual x-ray pulses on demand for high-resolution time-of-flight spectrometers. This allows for more precise band structure examinations in materials science.
French and American scientists used synchrotron holotomography to reveal the first fossil brain, a 300-million-year-old relative of sharks and ratfish. The discovery sheds light on brain evolution during major transitions and demonstrates the potential for microtomographic techniques in studying fossil brains.
