Climate change isn’t the only threat facing California’s birds. Over the course of the 20th century, urban sprawl and agricultural development have dramatically changed the landscape of the state, forcing many native species to adapt to new and unfamiliar habitats.

In a new study, biologists at the University of California, Berkeley, use current and historical bird surveys to reveal how land use change has amplified — and in some cases mitigated — the impacts of climate change on bird populations in Los Angeles and the Central Valley.

The study found that urbanization and much hotter and drier conditions in L.A. have driven declines in more than one-third of bird species in the region over the past century. Meanwhile, agricultural development and a warmer and slightly wetter climate in the Central Valley have had more mixed impacts on biodiversity.

“It’s pretty common in studies of the impact of climate change on biodiversity to only model the effects of climate and not consider the effects of land use change,” said study senior author Steven Beissinger, a professor of environmental science, policy and management at UC Berkeley and a researcher at the campus’s Museum of Vertebrate Zoology (MVZ). “But we’re finding that the individual responses of different bird species to these threats are likely to promote unpredictable changes that complicate forecasts of extinction risk.”

The study, publishing today in the journal Science Advances, presents the latest results from UC Berkeley’s Grinnell Resurvey Project, an effort to revisit and document birds and small mammals at sites first surveyed a century ago by UC Berkeley professor Joseph Grinnell.

Trikes. Trikes are the answer. E- trikes, with seats and canopies. Like the Edison. OK, that one isn't practucal but pretty cool. There are so many now though, take a minute and have a look.

I wonder if migraines could also be linked to high salt intake. As I have had two migraines in a short span of time in my life. Both were after having quite salty meals.

I've reduced the salt in my food since then, no more migraines have occurred.

For me they are kinda rare but when I do get them they aren’t the mean ones, usually I’ll end up in a sorta euphoria and will have an odd compulsion to eat snacks the sweeter the better and as much as I can as fast as I can, kinda like the munchies.

The first couple times it happened I thought it had something to do with diabetes because both of my grandfathers had it but nope the doctors weren’t sure.

Remember the rockhopper? They (Specialized) make really good ebikes now. Easy peas getting around. Pricey but check the specs and shop around.

Is complaining your middle name or just what you do for a job? Ahh, there it is, it should be your last name then. Like how people took on names according to their profession.

Yeah, I was wondering how they factored in quality of work, but from the abstract it sounds like they just...didn't?

There are options. The sooner we show all-route uptake, the more bike and e-commuter lanes will appear, as well as long country routes, connecting urban trails and bypasses. Start with weekend sports and work it your way. It's cheaper, quieter and healthier. For everyone.

Lazy rivers. Everybody floats to work

Using ensemble learning techniques and longitudinal data from a large naturalistic driving study, researchers at Columbia University Mailman School of Public Health, Fu Foundation School of Engineering and Applied Science, and Vagelos College of Physicians and Surgeons have developed a novel, interpretable and highly accurate algorithm for predicting mild cognitive impairment and dementia in older drivers. Digital markers refer to variables generated from data captured through recording devices in the real-world setting. These data could be processed to measure driving behavior, performance and tempo-spatial pattern in exceptional detail. The study is published in the journal Artificial Intelligence in Medicine.

The researchers used an interaction-based classification method for selecting predictive variables in the dataset. This learning model has achieved an accuracy of 96 percent in predicting mild cognitive impairment and dementia, outperforming traditional machine learning models such as logistic regression and random forests -- a statistical technique widely used in AI for classifying disease status. “Our new ensemble learning model based on digital markers and basic demographic characteristics can predict mild cognitive impairment and dementia in older drivers with excellent accuracy,” said Sharon Di, associate professor of civil engineering and engineering mechanics at Columbia Engineering and the study’s lead author.

The investigators constructed 200 variable modules using the naturalistic driving data on the driver, the vehicle and the environment captured by in-vehicle recording devices for 2977 drivers participating in the Longitudinal Research on Aging Drivers (LongROAD) project, a prospective cohort study conducted in five sites across the contiguous United States and sponsored by the AAA Foundation for Traffic Safety. At the time of enrollment, the participants were active drivers aged 65-79 years who were cognitively intact. Data used in this study came from the first three years of follow-up, spanning from August 2015 through March 2019. During the follow-up, 36 participants were diagnosed with mild cognitive impairment, 8 with Alzheimer’s disease, and 17 with other or unspecified dementia.

Some states want hundreds of hours and dollars for this- give me a break. Same with interior decorators.

When he asks if you could do a better job, what he is asking is if we have no laws because they are as you say "a farce", what is your preferable and more equitable system that would replace the function of laws and regulations in our modern society?

I'm surprised they didn't cover this form of rhetoric in your many philosophy and law degrees.

There's a significant safety & liability concern there. Hairdressers routinely apply potentially toxic and/or caustic chemicals directly to people's hair and scalp. Not to mention sharp cutting tools and very hot implements (curling irons, etc.). All in close proximity to, or even direct contact with, a person's face and neck.

Take a look on youtube electric vehicle channel: there is so much to see. Check the Aptera, the Vandersall Edison (so MG) and the Nobe with trailer, so Jetsons!

As a youth I used to get hunger migraines quite frequently. They could also be triggered by extreme stress, but that was much rarer. I would be in gym class mid-morning starving having only eaten cereal for breakfast. Then the scintillating scotoma would start, and I would end up with a migraine later in the day. Usually, they were extremely painful and confined me to bed but that was it.

As an adult, they became more infrequent but more severe. The scintillating scotoma stopped but if I went too long without eating I could "tell" I was going to get a migraine by what I craved after fasting (e.g., ice cream) and how I felt after I ate. The extreme pain would set in several hours later, followed by vomiting resulting in a vicious pain-vomit-pain cycle.

Thankfully I haven't had one in 20 years. Whenever I visit the doctor my bloodwork comes back normal. A1C, blood glucose, triglycerides, etc. I suspect it was/is metabolism related (with me anyway), specifically low blood sugar. Something that's become more regular and predictable as I've gotten older.

Glad they're getting to the bottom of it. Migraines run in my family but that didn't deter high school science teachers from telling me that I was lying about getting migraines because "only women get them."

This sounds like non-diabetic hypoglycemia.

I used to get migraines all the time until I graduated I use to think it was the super strong painkillers i took that stoppped them but maybe I just regulated my blood sugar better later on

China does have a relatively high incidence of cardiovascular disease, but they also don't have the same obesity crisis that america does. Having more risk factors like obesity and pollution significantly increases the incidences of heart attacks.

Yeah this is really interesting, I also don't have diabetes or anything but if I haven't eaten in a while I get hangry, then I start to shake and feel faint. I'm also super prone to bad headaches if I'm slightly tired or dehydrated. Never thought about it possibly being linked
