Secretary Buttigeg makes one of his final DOT stops at CMU's Safety 21

U.S. Secretary of Transportation Pete Buttigieg visited Carnegie Mellon University in one of his final stops as Transportation Secretary. Raj Rajkumar, director of Safety21 and George Westinghouse Professor in the Department of Electrical and Computer Engineering, with Ph.D. candidates Nishad Sahu and Gregory Su, demonstrated research on the safe navigation of autonomous driving systems in designated work zones, leveraging high-definition mapping, computer perception and vehicle connectivity. “The sophistication of the safety work that’s going on goes well beyond any commercially available automated or advanced driver assistance system is really inspiring,” Buttigieg said. “We’ve got to make sure it develops the right way, we’ve got to be cautious about how it’s deployed, but you can tell a lot of thought and, of course, a lot of incredibly sophisticated research is going into that.”

What the 2025 Tax Season May Look Like According to the IRS

The 2025 tax filing season will begin on Jan. 27. The Internal Revenue Service warns it may not be functioning as adequately due to the Republican-controlled congress rescinding IRS designated funding, causing cuts in staffing and potential technological updates to become stagnant. During the Biden administration the IRS was granted extra funding as part of the Inflation Reduction Act, passed exclusively with Democratic votes. The Trump administration has introduced a new scanning technology allowing tax returns to be filed quicker, upon the cut in previous IRS funding. This online filing system will allow taxpayers to file electronically with IRS for free, cutting out any unnecessary third party. There are concerns that the cut in funding may cause Trump's IRS updates to delay. How will the cut in IRS funding affect the 2025 tax season?  Economics expert, Dr. Jared Pincin weighs in on the discussion of how fund distribution will look under Trump administration in recent interview. Trump administration has cut funding for IRS from $80 Billion to $60 Billion through 2031. During his campaign for presidency Trump promised a reallocation for funding and distribution. How will we see Trump's policies redistribute funding?   Trump's new system, Direct File, is available in 24 states with hopes to make the 2025 tax season smoother than ever. Concerns arise that Trump's cut in funding to reallocate elsewhere may make his system to be come stagnant, causing delays and longer wait times for tax payers. Will Trump's new tax filing system make the 2025 tax season smoother or another nightmare?  President-elect Trump promised stricter tariffs on manufacturing industries and more aggressive industrial policies. Rescinding IRS funding is just the beginning of Trump's reallocation of funding. How will we see the change in funding affects businesses?

Are Trump's Economic Reforms Obsolete After Biden Administration

President-elect Donald Trump campaigns were filled with promises of economic reform including strict import tariffs, strict immigration curbs, and deregulation. However, reports reveal the current economic state of the US may not be needing the president's aggressive reform. Trends reflect a strong economy with low unemployment rate; prompting concerns that Trumps policies could disrupt the economic growth. Trump will be taking office next week with a much different economic circumstances compared to his first term in 2017. Does the economic changes since Trump's first term make his reforms obsolete or even dangerous? Economics expert, Dr. Jared Pincin weighs in on the discussion of the economy during the Biden administration in a recent interview. There has been an increase of individuals getting second jobs or "side hustles" especially in the Gen Z generation. As the need for an extra income source increased the unemployment rate has decreased. Are the lowered unemployment rates just a reflection of an economy that won't allow citizens to live on one paycheck? Although the economy that Trump will be inheriting show positive changes since his first term in 2017, there are concerns that can not be ignored. Trumps expansionary policies can incite inflation if the economy is not calling for his aggressive reforms. How will Trump's administration reap the benefits of the Biden administration while preventing an economic crisis? The economy appears to be performing well, especially over the past year. These reports come in during Trump's promises of reform. Are these reforms going to strengthen the economy or are they proof of Trumps disconnect with the current economic health?

When do we blame the tools?

Two recent incidents highlight concerns about AI misuse - a man used ChatGPT to plan an attack in Las Vegas, and AI video tools were exploited to create harmful content. These events sparked debate about regulating AI and holding developers accountable for potential harm caused by their technology. Carnegie Mellon University professor Vincent Conitzer explained that “our understanding of generative AI is still limited" and that we can't fully explain its success, predict its outputs, or ensure its safety with current methods.

A look at raw milk's health risks and potential benefits as Trump administration hints at law changes

More than half of U.S. states allow the sale of raw milk directly from farms to consumers, a number that would likely increase if Robert F. Kennedy Jr. – a raw milk advocate – is confirmed to lead the Department of Health and Human Services (DHHS). Kali Kniel, a professor of microbial food safety at the University of Delaware, can discuss the dangers and potential benefits of drinking raw milk. Some have celebrated the legalization of raw milk around the country, claiming it tastes better and has some nutritional benefits. Meanwhile, the U.S. Food and Drug Administration, one of the DHHS agencies Kennedy would lead, cautions against drinking raw milk, which comes directly from cows, sheep or goats and has been banned from being sold across state lines since the 1980s. Concerns regarding raw milk have been elevated as a deadly strain of bird flu is infecting dairy farms around the country. In the following Q&A, Kniel talks about the pathogens that may be present in raw milk, ways to communicate food safety to the public and other topics. Milk and other dairy products that sit on shelves at the grocery store are pasteurized. What does this process involve and why is it important for dairy products? Pasteurization of milk is a process of heating milk and passing it between heated stainless steel plates until it reaches 161 degrees Fahrenheit. It is held at that temperature for around 15 seconds before it is quickly cooled to 39 degrees Fahrenheit. This process is intended to kill the pathogenic bacteria that could make a person sick. How does this process affect milk’s quality and nutritional value? Scientific studies have shown that pasteurization does not significantly change the nutritional value of milk. Unpasteurized milk may have more vitamin C, which does not survive the pasteurization process, but milk is not considered a good source of vitamin C, as it contains less than 10% of the Recommended Dietary Allowance (RDA), the average amount of nutrients it takes to meet a healthy person’s needs. There are no beneficial bacteria in raw milk. Milk (pasteurized or raw) is not a good source of probiotic or potentially beneficial bacteria, so for that consumers should choose yogurt and other fermented dairy products as well as other fermented products. Scientific studies using animal models have shown no difference in how calcium in raw milk and pasteurized milk is absorbed by the human body. Popularity in drinking raw milk is increasing, despite the U.S. Food and Drug Administration advising that it’s not safe to drink. What are the health risks that come with drinking raw milk? Raw milk may contain pathogenic bacteria, including Campylobacter, Salmonella, pathogenic types of E. coli, Listeria and Brucella, as well as the protozoan parasite Cryptosporidium. These are all zoonotic microbes, which means they can be transmitted from animals to humans. Often the animal does not appear ill, so it is not possible to determine if an ill animal is shedding these pathogens in its feces that can contaminate milk. Microbial testing of the finished product and environmental monitoring programs may be helpful, but do not guarantee that the raw milk is absent of these pathogens. Milk can be contaminated with these pathogens from direct contamination with feces or from environmental conditions. Cross-contamination from dairy workers can also happen, even when people are trying their best to reduce the risk of cross-contamination. The likelihood of a disease outbreak occurring associated with a person consuming raw milk is relatively high given that others may also be exposed. Unpasteurized milk will have a relatively short shelf life and may not be available for testing. Following good hygiene practices on the farm and during milking such as biosecurity around the farm, appropriately sanitizing equipment and monitoring the health of animals can reduce the chance of milk contamination, but not eliminate it. There have been numerous outbreaks of illness associated with raw milk as well as cheese made from raw milk. Persons most at risk of illness associated with drinking raw milk include children, in particular 5 years of age and under, individuals aged 65 and over, pregnant women and immunocompromised individuals. It should be noted that all outbreaks of illness associated with raw milk have included individuals under 19 years of age. Children may be most vulnerable, as they cannot voice an opinion on consumption and risk of raw milk if it is in their household. The Center for Disease Control and Prevention (CDC) collects data on foodborne disease outbreaks voluntarily reported by state, local or territorial health departments. According to the CDC from 2013 to 2018 there were 75 outbreaks of illness linked to raw milk consumption. These outbreaks include 675 illnesses and 98 hospitalizations. Most of these illnesses were caused by Campylobacter, shiga-toxigenic E. coli, or Salmonella. An increase in outbreaks has been correlated with changes in the availability of raw milk. For example, between 2009 and 2023, there were 25 documented outbreaks in the state of Utah, which has 16 raw milk retailers licensed by the Utah Department of Agriculture and Food. In all of these outbreaks, the raw milk was contaminated with the bacteria Campylobacter, which typically causes gastroenteritis symptoms like diarrhea and nausea, but may also cause chronic illness, including Guillain-Barré syndrome which can cause paralysis. How likely are these illnesses to happen from drinking raw milk? It is difficult to say. Foodborne illness is often underreported, depending on how severe people’s symptoms are. According to one study, only about 3.2% of the U.S. population drinks raw milk, while about 1.6% eats cheese made from raw milk. But compared with consumers of pasteurized dairy products, they are 840 times more likely to experience an illness and 45 times more likely to be hospitalized. The authors of this work used the CDC’s national reporting system to analyze data from 2009 to 2014. Despite health risks, why do some people still drink raw milk? Some people feel a nostalgic connection to raw milk, and others may feel that foods that are not treated with heat retain certain nutrients and enzymatic activity. I am not aware of any peer-reviewed rigorous scientific studies that indicate the nutritional benefits of consuming raw milk over time, given the risks of potential for illness, combined with a well balanced diet full of healthful food choices. It remains that raw milk is particularly risky for children to consume, as children can get sick from consuming fewer bacterial cells compared to adults. More than 900 cases of highly pathogenic avian influenza — the disease commonly known as bird flu — have been detected in dairy cattle across 16 states, and at least 40 people have been infected with the disease from close contact with dairy cows. Raw milk is being tested for the virus. With raw milk gaining interest among consumers, what are the possible consequences? Does it elevate the risk of bird flu spreading further to people? There remain clear risks of transmission of pathogenic bacteria through consumption of raw milk, and now with the potential for contamination of raw milk with avian influenza, it is even more important that consumers protect themselves by drinking pasteurized milk. The people most at risk right now are those involved with the milking process and in the handling of dairy cattle. So it is important that those individuals be aware of the risks and take appropriate precautions, including hand washing and wearing appropriate personal protective equipment like protective clothing, gloves, face shields and eye protection. As of December, the U.S. Department of Agriculture is requiring 13 states to share raw milk samples so the agency can test for bird flu viruses. How could this testing better help us understand the virus? I think it is very smart that USDA is leading the National Milk Testing Strategy, which will help us understand the extent of infected herds. Surveillance of microorganisms is an important way to assess risk so we can develop appropriate strategies to reduce and control these risks.

Expert comment available - the Government's announcement for the AI Opportunities Action Plan

Expert comment is available on the the Government's announcement for the AI Opportunities Action Plan in which it is aims to roll out AI across the UK. In a speech setting out the government's plans to use AI across the UK to boost growth and deliver services more efficiently, the Prime Minister said the government had a responsibility to make AI "work for working people". The government claims that the AI Opportunities Action Plan is backed by leading tech firms, some of which have committed £14bn towards various projects, creating 13,250 jobs. It includes plans for growth zones where development will be focused, and the technology will be used to help tackle issues such as potholes. Expert comment: "The plan is a necessary step in the right direction with appropriate investment. It should be coupled with a major training programme at business and public levels to bridge the skill gap and develop essential capabilities. "It is important to specify the role that the higher education sector will play in the delivery of such a plan particularly with regards to innovation and knowledge transfer partnerships. "The government used stated that the technology will be used to help tackle issues such as potholes, however AI should be used not only in the detection of potholes, but also in their prediction. Using predictive analytics would significantly reduce the number of cameras that must be deployed to monitor road surface conditions up and down the country." Professor Abdul Hamid Sadka, Professor of Visual Media Technologies, Director, The Sir Peter Rigby Digital Futures Institute, Aston University For further details contact Nicola Jones, Head of Press & Communications (interim) on (+44) 7825 342091 or email: n.jones6@aston.ac.uk

The Days Blur Together: Study Shows How the COVID-19 Pandemic Affected Perceptions of Time… and Our Mental Well-being

Image Credit: Petrovich9/Getty Images Plus Although time is a set duration of hours, minutes and seconds, the perception of time can vary dramatically based on the individual and especially during times of high stress and uncertainty such as disasters, recessions and most recently the COVID-19 lockdown. For example, ask anyone when a specific event occurred during the pandemic and they are likely to respond with, “That happened three months ago. Or did that happen three years ago?” While there have been studies on the feeling that there is not enough time or experiencing time as moving too slowly, Baylor University sociologists Matthew Andersson, Ph.D., and Paul Froese, Ph.D., investigated this sense of multifaceted time perceptions during the pandemic and their effects on mental well-being. Their findings – using national Gallup data collected in spring 2021 in the middle of the pandemic – were published in the journal Time & Society. “We know from existing research that people often experience time in altered ways whenever disasters strike, and we wanted to see if that was true during the pandemic as well,” Andersson said. The Baylor researchers found that Americans during the pandemic generally reported some degree of feeling rushed while also perceiving multiple types of time distortion involving slowness, quickness and days and weeks blending together. This disorientation also was frequently reported alongside other pandemic-related stressors, including economic strain, working from home, homeschooling a child and severe household conflict. Together, they complicated how people perceive time by disrupting routines and creating experiences of trauma, adding to the decline in mental well-being and an increase in feelings of loneliness. Time disorientation and mental well-being The top three findings of the study all demonstrate the connection between altered time perception and the mental states of an individual. “If time does not seem to be moving ‘normally,’ it is generally related to lower levels of mental well-being, such as increased depressive, anxiety symptoms or a lessened sense of control,” Andersson said. “We think this is because people tend to feel grounded or calm when they feel like time is moving as it should.” Secondly, the researchers found that individuals can often experience these time disorientations in multiple and contradictory ways, which can be related to even lower well-being. “Feeling rushed and feeling that time is slow are kind of opposites, but they are both related to having this sense of multifaceted blending of time,” Froese said. “We can show very clearly how these new stresses that were brought on by the pandemic created heightened senses of disorientation in terms of time.” More importantly, they found these time disorientations were affected by social, familial, physical and work situations, which created lower levels of mental well-being. “Specific forms of stress we were seeing during the pandemic, such as financial hardship, homeschooling, working from home and severe household conflict, all had relationships to experiencing different kinds of time distortions,” said Andersson. This was more evident in younger people “because it [lockdown] probably upended their daily routines in a much more dramatic way than it would have in somebody who's retired,” said Froese. Experience of time The rushed pace of industrialized society existed before the COVID-19 pandemic, but the stressors associated with the pandemic added to the feelings of time being out of control. “Our approach to capturing experiences of time rests on the assumption that individuals relate to time in complex ways,” Froese said. “We found original evidence to suggest that experiences of quickness, being rushed, slowness and indistinct boundaries of days all coincide, and that these multiple disorientations each relate to diminished mental wellbeing, to objective work and family demands, and to widespread exposures to pandemic-related stressors.” The survey was conducted as part of the Baylor Religion Survey, one of the most extensive national surveys of American religious beliefs, values and behaviors that produces unique data concerning religion, health and community in America today. The 2021 data collection by Gallup contained a section devoted to how the pandemic affected Americans’ activities, including how the pandemic changed the emotional lives of Americans. Looking to know more? We can help. Dr. Paul Froese is a professor of sociology and a research fellow for the Institute for Studies of Religion. He has been teaching and researching at Baylor since 2002. Dr. Matthew Andersson’s research focuses on health inequality as it unfolds across the life course. Specifically, he researches educational and socioeconomic inequalities in mental and physical well-being as they relate to childhood, adolescent and adulthood factors.
