Chengdu, a bustling city, is on the brink of revolutionizing its transportation landscape by introducing Urban Air Mobility (UAM). A recent study named “A demand forecasting model for urban air mobility in Chengdu, China” conducted by a team of researchers from the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, proposes a sophisticated model to predict the future demand for UAM in Chengdu by 2030.
Urban Air Mobility refers to the use of Electric Vertical Take-Off and Landing (eVTOL) aircraft to transport people and goods across urban areas, potentially easing the notorious ground traffic congestion. As cities worldwide grapple with transportation inefficiencies, Chengdu’s initiative could serve as a blueprint for sustainable urban transit.
The study utilized a four-step forecasting method that includes trip generation, distribution, modal split, and traffic assignment to predict UAM demand. The researchers combined a nested logit (NL) model with a multinomial logit (MNL) model, overcoming the absence of historical UAM data to estimate future share rates effectively.
Key findings suggest that UAM will become a more competitive mode of transport as the travel distance increases, particularly surpassing 15 kilometers. This is due to eVTOLs’ ability to bypass traditional road traffic, significantly reducing travel time. The data indicates that for every additional kilometer, the UAM share rate could increase by 0.73%, making it a viable option for medium to long-range urban transport.
The study also highlights the importance of shared operation models for UAM. By fully implementing shared operations, where eVTOLs carry multiple passengers per trip, the UAM share rate could see a significant boost, making it an economically viable and environmentally friendly alternative to conventional road transport.
Furthermore, the research pinpoints routes within Chengdu that could benefit most from UAM, suggesting that prioritizing these routes could facilitate efficient UAM integration into the existing urban transport network. These routes predominantly cover areas with high traffic volumes and are expected to alleviate congestion significantly.
Despite its promising outlook, the integration of UAM in Chengdu faces several challenges. The success of this futuristic transportation hinges on several factors including technological advancements, regulatory approvals, public acceptance, and infrastructural developments. As UAM is still in its nascent stages globally, continuous research and adaptive strategies will be essential to its success.
The implications of this study extend beyond traffic management; they encompass economic benefits through job creation in the UAM sector and significant reductions in urban carbon emissions. As Chengdu aims to position itself at the forefront of urban transport innovation, the global community watches closely, potentially looking to replicate this model in other megacities facing similar urban mobility challenges.
This pioneering research not only maps out a feasible pathway for Chengdu's UAM adoption but also sets a benchmark for other cities aiming to integrate similar technologies into their urban landscapes. As we move towards more sustainable urban environments, Chengdu’s journey may well be a glimpse into the future of urban mobility.

Pancreatic cancer, recognized as one of the deadliest cancers, poses a persistent challenge for medical professionals globally due to its aggressive behavior and resistance to conventional therapies. The dense fibrotic tissue surrounding pancreatic tumors acts as a significant barrier, hindering the delivery of macromolecular drugs such as antibodies and nanomedicines. Therefore, addressing fibrosis is crucial in enhancing therapeutic outcomes for patients with pancreatic cancer, whose prognosis remains bleak.

DARIEN, IL – A new study to be presented at the SLEEP 2024 annual meeting found that circadian misalignment, which is highly prevalent in adolescents, is linked with carbohydrate consumption and sedentary behavior in teens.
Results show that a later sleep schedule was significantly associated with greater intake of carbohydrates, and this relationship was partially explained by irregular sleep timing. A later sleep schedule also was associated with greater sedentary behavior, even after adjusting for variables such as demographics, sleep disorders, and insufficient sleep.
“Delaying sleep schedules is normal during puberty and adolescence; however, some ...
DARIEN, IL – A new study to be presented at the SLEEP 2024 annual meeting found that it is common for foster caregivers to give melatonin to their child, and these children who have taken melatonin have worse sleep and more daytime behavioral problems.
Results show that 48% of foster caregivers reported administering melatonin to their child. Children given melatonin had poorer overall sleep quality compared to children not given melatonin, yet even after adjustment for sleep quality and other potential confounders, melatonin use was associated with increased severity of daytime behavioral problems in foster ...
Bronze cauldrons were used by the inhabitants of the Mongolian steppe around 2,700 years ago to process animal blood and milk. This is shown by a protein analysis of archaeological finds from this period.
Scattered across the Eurasian steppe, archaeologists repeatedly come across metal cauldrons from the Bronze Age during excavations. However, it was previously unclear exactly what they were used for. Now, an international study led by researchers at the University of Basel and published in the journal Scientific Reports reveals their secret: Mongolian nomads collected blood ...
Scientists have discovered genetic clues to the cause of restless leg syndrome, a condition common among older adults. The discovery could help identify those individuals at greatest risk of the condition and point to potential ways to treat it.
Restless leg syndrome can cause an unpleasant crawling sensation in the legs and an overwhelming urge to move them. Some people experience the symptoms only occasionally, while others get symptoms every day. Symptoms are usually worse in the evening or at night-time and can severely impair sleep.
Despite the condition ...
Scientists have detected what they believe to be a neutron star spinning at an unprecedentedly slow rate —slower than any of the more than 3,000 radio emitting neutron stars measured to date.
Neutron stars - the ultra-dense remains of a dead star - typically rotate at mind-bendingly fast speeds, taking just seconds or even a fraction of a second to fully spin on their axis.
However, the neutron star, newly discovered by an international team of astronomers, defies this rule, emitting radio signals on a comparatively ...
Even widespread species could be genomically vulnerable to the climate crisis, scientists warn. By studying the DNA of puddle frogs living in central African rainforests, the scientists found that areas of high environmental variation foster high genetic variation. If these varied habitats and the frogs that live there are lost, genetic variants that could have allowed the species to evolve to survive the climate crisis could be lost too. Meanwhile, populations with low genetic variation could become extinct quickly, unable to adapt.
“Generally, the more genomic variation within ...

More than 3.4 million people in the US and 65 million people worldwide have epilepsy, a neurological disorder that affects the nervous system and causes seizures. One in 26 people will develop epilepsy at some point in their lives, and 1 out of 1000 people with epilepsy die from unexpected deaths each year.
Like many conditions, epilepsy treatment starts with early detection. The World Health Organization estimates that 70% of people with epilepsy could live seizure-free if adequately diagnosed and treated.
Over the years, ...
