Big cars can make you feel safer. But here’s how the size of your vehicle affects others in a crash

Published

on

We see more big cars on our roads, especially large station wagon vehicles with four- or all-wheel drive, the so-called SUVs or SUVs. For every passenger automotive sold in Australia almost three SUVs were sold.

Vehicles similar to pickup trucks, large trucks, minivans and SUVs often offer greater protection for its residents than smaller cars. This is especially on account of their heavier weight and the way their structures are designed to soak up impacts. For drivers and passengers, this can mean less risk of injury in the event of a multi-vehicle collision.

However, these same characteristics increase the risk for passengers in smaller vehicles, pedestrians and cyclists. The front height of a large vehicle can compromise the passenger compartment of a smaller vehicle, and its greater mass can cause more severe impacts.

Perception of invincibility

Research shows that drivers imagine that larger vehicles are safer. This has a big impact on the decision which automotive to purchase (amongst other aspects similar to prestige and field capabilities).

Perceptions of safety can potentially reduce a driver’s risk aversion, resulting in more dangerous driving behavior, e.g adopting less cautious hand positions on the steering wheel. SUV drivers usually tend to drive with one hand (versus the hand at 10-2 o’clock), which suggests that they feel safer than other automotive drivers.

Impact on collisions

Study with Netherlands found a significant increase in the risk of death for heavier vehicles.

This has also been seen in the United States, where a study showed a rise in vehicle weight of 500 kilograms, which could mean the difference between an SUV and a sedan, correlates with a 70% greater risk of death.

Heavier vehicles cause more serious injuries.

The Standard adapted to the height of the bumper from 2003 which aimed to scale back the severity of accidents between SUVs/pickups and passenger cars. By equalizing the bumper heights of these vehicles, their bumpers would engage properly during a collision, improving the distribution of crash forces and higher protecting passengers.

But it happened mixed results. It barely reduced the risk of death in side impacts, but was less effective in frontal impacts. This suggests that further safety improvements are needed to effectively address the effects of vehicle-to-vehicle collisions.

The probability the number of SUVs causing fatalities amongst drivers of other cars has decreased from 132% more prone to collide with an SUV in the early Nineties to twenty-eight% more likely in 2016. The likely causes of this decline are the implementation bumper compliant with height standardand enhancements in vehicle design: implementation crumple zonesimproved side-impact protection and advanced safety features similar to electronic stability control.

However, we didn’t see a similar improvement for pickup trucks, suggesting that weight is a possible cause of the increased risk of fatalities.

What about pedestrians and cyclists?

Pedestrians usually tend to be fatally injured in a collision with a large vehicle than a passenger automotive.

The design of these vehicles, especially their higher front end, significantly increases the risk. Just a 10-centimeter increase in front height can make it taller risk of pedestrian death by 22%with impacts more prone to occur at critical injury points similar to the chest or head.

The research have shown correlation between the increase in sales of larger vehicles similar to SUVs and the increase in pedestrian fatalities in the United States from 2000 to 2019. Kids If the risk of death in an SUV collision is eight times greater in comparison with lighter and smaller cars.

Scientists estimate that replacing larger vehicles with smaller cars in 2019 could prevent approx This yr alone, 460 pedestrians have died in the US.

Computer simulations examined the effects of automotive accidents on the human brain of pedestrians, comparing the effects of being struck by an SUV and a sedan. SUVs exert twice the force on the brain than sedans while traveling at comparable speeds, significantly increasing the risk of serious injury even before direct head contact occurs.

Computer simulations also showed that vehicles with high noses were the cause pedestrians hitting the ground at higher speeds.

Cyclist injuries from SUV accidents They were also found to be rather more severe than those resulting from automotive accidents, with a particular increase in the severity of head injuries in collisions involving SUVs.

This difference in injury severity is attributed to the design of SUVs, which usually tend to cause cyclists to hit the ground or cause injury.

Impact on collisions on the driveway

Large vehicles increase the risk of driveway accidents, especially involving children under five, because their design often limits rear visibility.

Some eight years of study in Utah 495 vehicle and pedestrian injuries were identified, of which 128 occurred on driveways. These crashes disproportionately involved larger vehicles similar to SUVs, trucks and vans on account of their large blind spots.

Find Thoth” The public awareness campaign and similar initiatives aim to combat these incidents by promoting safety practices similar to visual inspection behind the vehicle before driving away.

The advent and adoption of technologies similar to reversing cameras and parking sensors have greatly improved visibility, reduction of dead zones by roughly 90%.

Despite these advances, the need for increased driver awareness and precautions stays critical.

Stopping the vehicle arms race

As more drivers select larger vehicles under the guise of personal safety, they might inadvertently endanger the safety of pedestrians and other road users. For every fatal accident someone avoided in a large vehicle, there have been at the very least 4.3 additional fatal accidents engaging others.

Changing the trend towards larger cars requires strong policy and (discouraging) incentives. Currently exists discussion to impose higher taxes and/or registration fees on SUVs and bigger cars, particularly because of their impact on the safety of others.

In some places like Parisheavier vehicles are discouraged by tripling parking rates for cars over a certain weight.

However, given the popularity of large vehicles, such a policy change is not going to be easy.

Jury awarded $310 million to parents of teenager who died after falling on a ride at Florida amusement park – Essence

Published

The family of Tire Sampson, the 14-yr-old who tragically died on an amusement park ride in Orlando, Florida, in 2022, has been awarded $310 million in a civil lawsuit.

Tire, who was visiting ICON Park along with his family on March 24, 2022, fell from the FreeFall drop tower. Although he was taken to a nearby hospital, he didn’t survive his injuries.

Now, greater than two years later, a jury has held the vehicle manufacturer, Austria-based Funtime Handels, responsible for the accident and awarded the Tire family $310 million. According to reports from local news stations WFTV AND KSDKthe jury reached its verdict after about an hour of deliberation.

Tyre’s parents will each receive $155 million, according to attorney spokesman Michael Haggard.

Attorneys Ben Crump and Natalie Jackson, who represented Tyre’s family, shared their thoughts on this landmark decision via X (formerly Twitter). “This ruling is a step forward in holding corporations accountable for the safety of their products,” they said in a statement.

Lawyers stressed that Tyre’s death was attributable to “gross negligence and a failure to put safety before profits.” They added that the ride’s manufacturer had “neglected its duty to protect passengers” and that the substantial award ensured it could “face the consequences of its decisions.”

Crump and Jackson said they hope the result will encourage change throughout the theme park industry. “We hope this will spur the entire industry to enforce more stringent safety measures,” they said. “Tire heritage will provide a safer future for drivers around the world.”

An investigation previously found that Tyre’s harness was locked through the descent, but he dislodged from his seat through the 430-foot fall when the magnets engaged. Tire’s death was ruled the result of “multiple injuries and trauma.”

ICON Park said at the time that it could “fully cooperate” with the authorities.

Tireless HIV/AIDS advocate A. Cornelius Baker dies

Published

By

HIV/AIDS Advocate, A. Cornelius Baker


A. Cornelius Baker, a tireless advocate of HIV and AIDS testing, research and vaccination, died Nov. 8 at his home in Washington, D.C., of hypertensive, atherosclerotic heart problems, in response to his partner, Gregory Nevins.

As previously reported, Baker was an early supporter for people living with HIV and AIDS within the Nineteen Eighties, when misinformation and fear-mongering in regards to the disease were rampant.

According to Douglas M. Brooks, director of the Office of National AIDS Policy under President Obama, it was Baker’s Christian faith that guided him toward compassion for others.

“He was very kind, very warm and inclusive – his circles, both professional and personal, were the most diverse I have ever seen, and he was guided by his Christian values,” Brooks told the outlet. “His ferocity was on display when people were marginalized, rejected or forgotten.”

In 1995, when he was executive director of the National AIDS Association, Baker pushed for June 27 to be designated National HIV Testing Day.

In 2012, he later wrote on the web site of the Global Health Advisor for which he was a technical advisor that: “These efforts were intended to help reduce the stigma associated with HIV testing and normalize it as part of regular screening.”

Baker also feared that men like himself, black gay men, and other men from marginalized communities were disproportionately affected by HIV and AIDS.

Baker pressured the Clinton administration to incorporate black and Latino people in clinical drug trials, and in 1994 he pointedly told the Clinton administration that he was bored with hearing guarantees but seeing no motion.

According to Lambda Legal CEO Kevin Jennings, yes that daring attitude that defines Baker’s legacy in the world of ​​HIV/AIDS promotion.

“Cornelius was a legendary leader in the fight for equality for LGBTQ+ people and all people living with HIV,” Jennings said in a press release. “In the more than twenty years that I knew him, I was continually impressed not only by how effective he was as a leader, but also by how he managed to strike the balance between being fierce and kind at the same time. His loss is devastating.”

Jennings continued: “Cornelius’ leadership can’t be overstated. For many years, he was one in all the nation’s leading HIV/AIDS warriors, working locally, nationally and internationally. No matter where he went, he proudly supported the HIV/AIDS community from the Nineteen Eighties until his death, serving in various positions including the Department of Health and Human Services, the National Association of Persons with Disabilities AIDS, and the Whitman-Walker Clinic . Jennings explained.

Jennings concluded: “His career also included several honors, including being the first recipient of the American Foundation for AIDS Research Foundation’s organization-building Courage Award. Our communities have lost a pillar in Cornelius, and as we mourn his death, we will be forever grateful for his decades of service to the community.”

Kaye Hayes, deputy assistant secretary for communicable diseases and director of the Office of Infectious Diseases and HIV/AIDS Policy, in her comment about his legacy, she called Baker “the North Star.”.

“It is difficult to overstate the impact his loss had on public health, the HIV/AIDS community or the place he held in my heart personally,” Hayes told Hiv.gov. “He was pushing us, charging us, pulling us, pushing us. With his unwavering commitment to the HIV movement, he represented the north star, constructing coalitions across sectors and dealing with leaders across the political spectrum to deal with health disparities and advocate for access to HIV treatment and look after all. He said, “The work isn’t done, the charge is still there, move on – you know what you have to do.” It’s in my ear and in my heart in the case of this job.

Hayes added: “His death is a significant loss to the public health community and to the many others who benefited from Cornelius’ vigilance. His legacy will continue to inspire and motivate us all.”

Baker is survived by his mother, Shirley Baker; his partner Nevins, who can be senior counsel at Lambda Legal; his sisters Chandrika Baker, Nadine Wallace and Yavodka Bishop; in addition to his two brothers, Kareem and Roosevelt Dowdell; along with the larger HIV/AIDS advocacy community.

Bovaer is added to cow feed to reduce methane emissions. Does it pass into milk and meat? And is it harmful to humans?

Published

on

By

There are growing concerns in regards to the use of feed supplements, Bowar 10to reduce methane production in cows.

Bovaer 10 consists of silicon dioxide (mainly sand), propylene glycol (food stabilizer approved by Food Safety Australia New Zealand) and lively substance 3-nitrooxypropanol (3-NOP).

There has been an enormous amount of misinformation in regards to the safety of 3-NOP, with some milk from herds fed this additive being labeled “Frankenmilk”. Others feared it could get to humans through beef.

The most significant thing is that 3-NOP is secure. Let’s clear up some major misconceptions.

Why do we want to limit methane production?

In our attempts to limit global warming, we’ve placed the best emphasis on CO₂ because the major man-made greenhouse gas. But methane is also a greenhouse gas, and although we produce less of it, it is: a much stronger greenhouse gas than CO₂.

Agriculture is the largest a man-made source of methane. As cattle herds expand to meet our growing demand for meat and milk, reducing methane production from cows is a vital way to reduce greenhouse gas emissions.

There are several ways to do that. Stopping bacteria within the stomachs of cows that produce methane one approach is to produce methane.

The methane produced by cows and sheep doesn’t come from the animals themselves, but from the microbes living of their digestive systems. 3-NO stop the enzymes that perform the last step of methane synthesis in these microorganisms.

3-NOP is not the one compound tested as a feed additive. Australian product based on seaweed, Rumin8for instance, it is also in development. Saponins, soap-like chemicals present in plants, and essential oils as well has been examined.

However, 3-NOP is currently one of the popular effective treatments.

But is not it poison?

There are concerns on social media that Bovaer is “poisoning our food.”

But, as we are saying in toxicology, it’s the dose that makes the poison. For example, arsenic is deadly 2–20 milligrams per kilogram of body weight.

In contrast, 3-NOP was not lethal on the doses utilized in safety studies, up to 600 mg 3-NOP per kg body weight. At a dose of 100 mg per kg body weight in rats, it didn’t cause any adversarial effects.

What about reproductive issues?

The effect of 3-NOP on the reproductive organs has generated numerous commentary.

Studies in rats and cows showed that doses of 300–500 mg per kg body weight caused: contraction of the ovaries and testicles.

In comparison, to achieve the identical exposure in humans, a 70 kg human would want to eat 21–35 grams (about 2 tablespoons) of pure 3-NOP every day for a lot of weeks to see this effect.

No human will likely be exposed to this amount because 3-NOP doesn’t pass into milk – is fully metabolized within the cow’s intestines.

No cow will likely be exposed to these levels either.

What about cancer?

3-NOP is not genotoxic or mutagenicwhich implies it cannot damage DNA. Thus, the results of 3-NOP are dose-limited, meaning that small doses will not be harmful, while very high doses are (unlike radiation where there is no secure dose).

Scientists found that at a dose of 300 mg per kilogram of body weight benign tumors of the small intestine of female ratsbut not male rats, after 2 years of every day consumption. At a dose of 100 mg 3-NOP per kg body weight, no tumors were observed.

Cows eat lower than 2 grams of Bovaer 10 per day (of which only 10% or 0.2 grams is 3-NOP). This is about 1,000 times lower than the appropriate every day intake 1 mg 3-NOP per kg body weight per day for a cow weighing 450 kg.

This level of consumption will likely be not the result in cancer or any of them other adversarial effects.

So how much are people exposed to?

Milk and meat consumers will likely be exposed to zero 3-NOP. 3-NOP doesn’t penetrate milk and meat: is completely metabolized within the cow’s intestines.

Farmers could also be exposed to small amounts of the feed additive, and industrial employees producing 3-NOP will potentially be exposed to larger amounts. Farmers and industrial employees already wear personal protective equipment to reduce exposure to other agricultural chemicals – and it is advisable to do that with Bovear 10 as well.

How widely has it been tested?

3-NOP has been in development for 15 years and has been subject to multiple reviews by European Food Safety Authority, UK Food Safety Authority AND others.

It has been extensively tested over months of exposure to cattle and has produced no unintended effects. Some studies actually say so improves the standard of milk and meat.

Bovaer was approved for use in dairy cattle by the European Union from 2022 and Japan in 2024. It is also utilized in many other countries, including: in beef products, amongst others Australia.

A really small amount of 3-NOP enters the environment (lower than 0.2% of the dose taken), no accumulates and is easily decomposed subsequently, it doesn’t pose a threat to the environment.

Since humans will not be exposed to 3-NOP through milk and meat, long-term exposure is not an issue.

What does Bill Gates have to do with this?

Bill Gates has invested in a distinct feed processing method for methane, Australian seaweed-based Rumin8. But he has nothing to do with Bovaer 10.

The Bill & Melinda Gates Foundation awarded research grants to the corporate producing 3-NOP for malaria control researchnot for 3-NOP.

The bottom line is that adding 3-NOP to animal feed doesn’t pose any risk to consumers, animals or the environment.
