7 wild ways pregnancy changes your body forever

Popular Science

Hormones, shifting organs, and a growing baby can leave permanent marks. Breakthroughs, discoveries, and DIY tips sent six days a week. We've all seen the photos: a celebrity gives birth on Tuesday and looks flawless in a bikini by Thursday. Meanwhile, the rest of us are still trying to figure out what happened to our feet. The truth is pregnancy causes some surprising long-term changes to your body, regardless of whether you're a celebrity or a soccer mom.





Airports embrace AI to manage growing global passenger traffic

Al Jazeera

As global air passenger traffic is forecast to hit 10.2 billion in 2026, a 3.9 percent year-on-year increase, investments have been pouring in to improve airport infrastructure and operational efficiency and use artificial intelligence to achieve it. Working with data released by Airport Council International, a irports are relying on the increasing use of AI to embrace the rise in demand. The use of AI-powered analytics to anticipate congestion at security, immigration and boarding points is also helping to prevent delays. Resources are being allocated to shift from reactive crowd management to predictive operations. AI-powered baggage optimisation tools and biometric processing - which would allow passengers to walk through immigration without the need to present a physical passport - are also gaining traction as airports seek to improve passenger experience while maintaining operational efficiency.


More than 700 officers to police Villa-Maccabi match

BBC News

Warnings of disruption and protests have come from police as more than 700 officers prepare to mount an operation in Birmingham for Aston Villa's Uefa Europa League match against Maccabi Tel Aviv. Officers will be keeping the public safe and to tackle any crime and disorder on Thursday, West Midlands Police said, with police horses, dogs, the force's drone unit, and road policing officers out in the city. Planned protests include one by supporters of Palestine, who want the match to be called off. Last month, a decision to ban Tel Aviv fans from the event became the focus of parliamentary-level debate . The Israeli club later said supporters would not travel to Birmingham for safety reasons.


Can AI and automated planes help prevent plane crashes?

Al Jazeera

More than 100 people have been killed in air crashes this year already, including in a midair collision between a commercial airliner and a helicopter near Washington, DC, and a plane crashing into a bus on a Sao Paulo street. The fatal incidents in the first two months of the new year came after last year was declared one of the deadliest in aviation history with at least 318 deaths in 11 civilian airplane crashes, including two incidents in the last week of December. While fatal air crashes are rare, they attract extraordinary attention, often reinstilling the fear of flying. At least 25 million adults in the United States alone have a fear of flying, according to the Cleveland Clinic. The fear is often exacerbated not just by the crashes but also incidents like emergency landings, a door blowing off a plane and aircraft skidding off runways.

This paper examines third-order co-occurrence statistics of edges in natural images. The main finding is that triples of edges co-occur in ways consistent with smooth flows, elongated along the tangent direction. Better statistical models of the geometry of natural image structure are crucial to understanding biological vision as well as making progress in computer vision, and the authors are correct in their claim that to date most models have focused on 2nd-order relationships, particularly the joint distribution of pairs of edges. Thus the investigation of higher-order statistics is of great interest. Overall the methods seem sound.


Hand-Object Interaction Pretraining from Videos

arXiv.org Artificial Intelligence

Reusable sensorimotor representations have the potential to give robots access to the versatility of their sensorimotor apparatus, thereby enabling them to achieve a wide variety of goals. Similar to advancements in other AI domains [1, 2], such representations are likely to be trained with unsupervised objectives on large datasets. In this work, we study the feasibility of training such representations using human videos in the context of dexterous manipulation. Using videos as a data engine comes with several advantages: (1) they are abundant; (2) they cover a wide range of skills that we want robots to master; and (3) they reflect natural or socially acceptable behaviors that we want robots to emulate. However, training sensorimotor representations on videos is a challenging endeavor.


High-Quality and Full Bandwidth Seismic Signal Synthesis using Operational GANs

arXiv.org Artificial Intelligence

Vibration sensors are essential in acquiring seismic activity for an accurate earthquake assessment. The state-of-the-art sensors can provide the best signal quality and the highest bandwidth; however, their high cost usually hinders a wide range of applicability and coverage, which is otherwise possible with their basic and cheap counterparts. But, their poor quality and low bandwidth can significantly degrade the signal fidelity and result in an imprecise analysis. To address these drawbacks, in this study, we propose a novel, high-quality, and full bandwidth seismic signal synthesis by transforming the signal acquired from an inferior sensor. We employ 1D Operational Generative Adversarial Networks (Op-GANs) with novel loss functions to achieve this. Therefore, the study's key contributions include releasing a new dataset, addressing operational constraints in seismic monitoring, and pioneering a deep-learning transformation technique to create the first virtual seismic sensor. The proposed method is extensively evaluated over the Simulated Ground Motion (SimGM) benchmark dataset, and the results demonstrated that the proposed approach significantly improves the quality and bandwidth of seismic signals acquired from a variety of sensors, including a cheap seismic sensor, the CSN-Phidgets, and the integrated accelerometers of an Android, and iOS phone, to the same level as the state-of-the-art sensor (e.g., Kinemetrics-Episensor). The SimGM dataset, our results, and the optimized PyTorch implementation of the proposed approach are publicly shared.
