CNN — Ukrainian forces said they had penetrated the “first line” of Russian strongholds in the Zaporizhzhia region, in a sign that Kyiv is edging closer to Moscow’s sprawling network of fortified trenches along the southern front. The Ukrainian military claimed on Thursday that its units had advanced towards two…
CNN — A Russian official claimed Thursday that a Ukrainian sabotage operation had been foiled in Bryansk, southwestern Russia, with several Ukrainians killed or captured. Alexander Bogomaz, governor of the Bryansk region that borders both Ukraine and Belarus, said on his Telegram channel that two of the group had died…
A new blood test called p-tau217 shows promise as an Alzheimer’s disease biomarker, and when used in a two-step workflow very high accuracy to either identify or exclude brain amyloidosis, the most important and earliest pathology. That is an innovation now presented by researchers at the University of Gothenburg, together…
A robot moves a toy package of butter around a table in the Intelligent Robotics and Vision Lab at The University of Texas at Dallas. With every push, the robot is learning to recognize the object through a new system developed by a team of UT Dallas computer scientists. The…
A team of UCL-led researchers has developed a new method to determine the attention levels of drivers and their readiness to respond to warning signals when using auto-pilot mode. The research, published in Cognitive Research: Principles and Implications, found that people’s attention levels and how engrossed they are in on-screen…
From the early stages of cell mutations starting in puberty to their manifestations as breast cancer in later years, the entire process has remained shrouded in mystery. Now, a team of researchers at Kyoto University has revealed the mechanism by which breast cancer is formed in the cells of the…
A novel study from the University of South Australia has identified a range of metabolic biomarkers that could help predict the risk of cancer.

Scientists from The University of New Mexico (UNM), and Massachusetts Institute of Technology (MIT) have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which…
A team of researchers at the University of Waterloo and Dalhousie University have developed a method for forecasting the short-term progression of an epidemic using extremely limited amounts of data. Their model, the Sparsity and Delay Embedding-based Forecasting model, or SPADE4, uses machine learning to predict the progression of an…
By controlling the arrangement of multiple inorganic and organic layers within crystals using a novel technique, researchers at Duke University and Purdue University have shown they can control the energy levels of electrons and holes (positive charge carriers) within a class of materials called perovskites. This tuning influences the materials’…
Patulin is a harmful mycotoxin produced by fungi typically found in damaged fruits, including apples, pears, and grapes. In a recent breakthrough, researchers from Japan identified a new filamentous fungal strain that can degrade patulin by transforming it into less toxic substances. Their findings provide important insights into the degradation…
What is the risk of a volcano erupting? To answer this question, scientists need information about its underlying internal structure. However, gathering this data can take several years of fieldwork, analyses and monitoring, which explains why only 30% of active volcanoes are currently well documented. A team from the University…
A team of researchers from the Department of Interface Science at the Fritz Haber Institute of the Max Planck Society addressed the question: what happens to a Ga-promoted Cu surface under reaction conditions required for the synthesis of methanol?
