NoneA multibillion-dollar plan to create “clean” hydrogen from brown coal and ship it to Japan is on the brink of collapse, according to Japanese media reports suggesting that Kawasaki Heavy Industries has withdrawn from the trial, blaming procurement delays. The controversial plan was billed as a lifeline for the Latrobe Valley’s ageing brown coal industry. Under the plan, hydrogen would be extracted from coal, creating the world’s first liquefied hydrogen supply chain.

It was also to send the super-cooled hydrogen extracted from coal in purpose-built bulk carriers out of Hastings to Kawasaki in the Asian nation’s industrial heartland. The Hydrogen Energy Supply Chain project (HESC) was a partnership between international fossil energy companies, including Kawasaki Heavy Industries Ltd (KHI), Royal Dutch Shell and AGL. Japanese outlet Nikkei reported that Kawasaki Heavy Industries had abandoned its bid to establish an international supply chain to procure hydrogen from Australia because it had become “difficult to procure hydrogen in Australia within the deadline”. “With the completion of the demonstration test by fiscal year 2030, as originally scheduled, being an absolute requirement for ensuring competitiveness, the company has changed hydrogen procurement to domestic,” Nikkei reported. “It has also downsized its hydrogen carriers and is now steering toward a more ‘realistic’ solution.” Victorian Energy Minister Lily D’Ambrosio raised doubts about the project last year at an Australian Financial Review Energy and Climate Summit, saying it was not clear that the proponents would be able to adequately capture the carbon from the coal and safely sequester it. “That is a question that is yet to be answered,” she said. The AFR reported that Kawasaki Heavy Industries’ chairman Yoshinori Kanehana told a separate event last year that his business had been focused on winning “social license” from Victorian communities and hoped to avoid “ideological divides”. Friends of the Earth gas campaigner Freja Leonard said Kawasaki Heavy Industries’ decision to withdraw indicated the project wasn’t financially or practically feasible. “It’s just an absolute nonsense to use brown coal in a climate crisis to produce hydrogen,” she said. “Hydrogen is notoriously difficult to contain. It’s incredibly expensive to produce, and any project that expects to successfully ship hydrogen from one country to another without significant leakage is doomed to failure.” A commercial-in-confidence report on the proposal compiled by the Department of Industry, Science and Resources in 2022 and released under freedom of information laws argued the plan was broadly supported in the Latrobe Valley. “There are a limited number of groups within the Latrobe Valley that do not support the use of fossil fuels and are against CCS [carbon capture and storage],” it stated. “However, the predominant sentiment in the Valley is one that supports the HESC [Hydrogen Energy Supply Chain].” Identifying challenges getting stakeholders like the local council on board, the report noted that the HESC had “revised [its] messaging”, “highlighting the carbon neutrality” the project could achieve by combining biomass with coal. This, it said, “softens the image of HESC as a coal-driven project”. Under the plan, the cooled hydrogen would have been piped more than 150 kilometres from Gippsland to the Port of Hastings and shipped to Japan. In January 2022, according to the confidential report, hydrogen was successfully generated under trial from brown coal and biomass. However, it reported cost overruns and lengthy delays to the trial.

Syra Health to Present at NobleCon20Analyzing multiple mammograms improves breast cancer risk prediction December 5, 2024 Washington University School of Medicine A new method of analyzing mammograms identified individuals at high risk of developing breast cancer more accurately than the standard, questionnaire-based method did. The new method, powered by artificial intelligence, could help diagnose cancer earlier and guide recommendations for earlier screening, additional imaging or risk-reducing medications. Facebook Twitter Pinterest LinkedIN Email A new study from Washington University School of Medicine in St. Louis describes an innovative method of analyzing mammograms that significantly improves the accuracy of predicting the risk of breast cancer development over the following five years. Using up to three years of previous mammograms, the new method identified individuals at high risk of developing breast cancer 2.3 times more accurately than the standard method, which is based on questionnaires assessing clinical risk factors alone, such as age, race and family history of breast cancer. The study is published Dec. 5 in JCO Clinical Cancer Informatics . "We are seeking ways to improve early detection, since that increases the chances of successful treatment," said senior author Graham A. Colditz, MD, DrPH, associate director of Siteman Cancer Center, based at Barnes-Jewish Hospital and WashU Medicine, and the Niess-Gain Professor of Surgery. "This improved prediction of risk also may help research surrounding prevention, so that we can find better ways for women who fall into the high-risk category to lower their five-year risk of developing breast cancer." This risk-prediction method builds on past research led by Colditz and lead author Shu (Joy) Jiang, PhD, a statistician, data scientist and associate professor of surgery in the Division of Public Health Sciences at WashU Medicine. The researchers showed that prior mammograms hold a wealth of information on early signs of breast cancer development that can't be perceived even by a well-trained human eye. This information includes subtle changes over time in breast density, which is a measure of the relative amounts of fibrous versus fatty tissue in the breasts. For the new study, the team built an algorithm based on artificial intelligence that can discern subtle differences in mammograms and help identify those women at highest risk of developing a new breast tumor over a specific timeframe. In addition to breast density, their machine-learning tool considers changes in other patterns in the images, including in texture, calcification and asymmetry within the breasts. "Our new method is able to detect subtle changes over time in repeated mammogram images that are not visible to the eye," said Jiang, yet these changes hold rich information that can help identify high-risk individuals. At the moment, risk-reduction options are limited and can include drugs such as tamoxifen that lower risk but may have unwanted side effects. Most of the time, women at high risk are offered more frequent screening or the option of adding another imaging method, such as an MRI, to try to identify cancer as early as possible. "Today, we don't have a way to know who is likely to develop breast cancer in the future based on their mammogram images," said co-author Debbie L. Bennett, MD, an associate professor of radiology and chief of breast imaging for the Mallinckrodt Institute of Radiology at WashU Medicine. "What's so exciting about this research is that it indicates that it is possible to glean this information from current and prior mammograms using this algorithm. The prediction is never going to be perfect, but this study suggests the new algorithm is much better than our current methods." AI improves prediction of breast cancer development The researchers trained their machine-learning algorithm on the mammograms of more than 10,000 women who received breast cancer screenings through Siteman Cancer Center from 2008 -- 2012. These individuals were followed through 2020, and in that time 478 were diagnosed with breast cancer. The researchers then applied their method to predict breast cancer risk in a separate set of patients -- more than 18,000 women who received mammograms through Emory University in the Atlanta area from 2013 -- 2020. Subsequently, 332 women were diagnosed with breast cancer during the follow-up period, which ended in 2020. According to the new prediction model, women in the high-risk group were 21 times more likely to be diagnosed with breast cancer over the following five years than were those in the lowest-risk group. In the high-risk group, 53 out of every 1,000 women screened developed breast cancer over the next five years. In contrast, in the low-risk group, 2.6 women per 1,000 screened developed breast cancer over the following five years. Under the old questionnaire-based methods, only 23 women per 1,000 screened were correctly classified in the high-risk group, providing evidence that the old method, in this case, missed 30 breast cancer cases that the new method found. The mammograms were conducted at academic medical centers and community clinics, demonstrating that the accuracy of the method holds up in diverse settings. Importantly, the algorithm was built with robust representation of Black women, who are usually underrepresented in development of breast cancer risk models. The accuracy for predicting risk held up across racial groups. Of the women screened through Siteman, most were white, and 27% were Black. Of those screened through Emory, 42% were Black. In ongoing work, the researchers are testing the algorithm in women of diverse racial and ethnic backgrounds, including those of Asian, southeast Asian and Native American descent, to help ensure that the method is equally accurate for everyone. The researchers are working with WashU's Office of Technology Management toward patents and licensing on the new method with the goal of making it broadly available anywhere screening mammograms are provided. Colditz and Jiang also are working toward founding a start-up company around this technology. Jiang S, Bennett DL, Rosner BA, Tamimi RM, Colditz GA.

Los Angeles Chargers rookie wide receiver Ladd McConkey, listed as questionable due to a shoulder issue, is expected to play Monday night against the visiting Baltimore Ravens, NFL Network reported. McConkey missed practice on Thursday and was limited on Friday and Saturday. Star linebacker Khalil Mack, who was questionable because of a groin injury and was a limited participant, also is expected to play, according to the report. The Chargers (7-3) made several moves Monday ahead of the game against the Ravens (7-4), placing tight end Hayden Hurst (hip) on injured reserve, activating cornerback Deane Leonard (hamstring) off IR, signing cornerback Eli Apple from the practice to the active squad, and elevating linebacker Caleb Murphy and safety Tony Jefferson for game day. McConkey, 23, has started nine of 10 games and has 43 receptions on 63 targets for 615 yards and four touchdowns. The Chargers drafted the 6-foot, 185-pound McConkey in the second round of the 2024 NFL Draft out of Georgia. Mack, 33, is a three-time first-team All-Pro, an eight-time Pro Bowl selection and the 2016 NFL Defensive Player of the Year. He has started the nine games he has played and has 26 tackles and 4.5 sacks this season. For his career, Mack has 617 tackles, 106 sacks, 141 tackles for loss, 178 quarterback hits, three interceptions -- two returned for touchdowns -- 32 forced fumbles and 13 fumble recoveries in 160 games (159 starts). He has played for the Raiders (2014-17), Chicago Bears (2018-21) and Chargers. Hurst, 31, has started two of seven games in his first season with the Chargers. He has seven receptions on 12 targets for 65 yards. A first-round pick (25th overall) by Baltimore in the 2018 NFL Draft out of South Carolina, Hurst has 202 receptions for 1,967 yards and 15 TDs in 86 games (41 starts) for the Ravens (2018-19), Atlanta Falcons (2020-21), Cincinnati Bengals (2022), Carolina Panthers (2023) and Chargers. Apple, 29, has two tackles in three games this season, his first with the Chargers. The 10th overall selection in the 2016 draft, Apple has 383 career tackles and six interceptions in 101 games (82 starts) for the New York Giants (2016-18), New Orleans Saints (2018-19), Panthers (2020), Bengals (2021-22), Miami Dolphins (2023) and Chargers. Leonard, who turned 25 last Tuesday, has four tackles in four games this season. His 21-day practice window on IR opened Wednesday. --Field Level MediaSAN JOSE, Calif. — A bid by the co-captain of San Jose State University’s women’s volleyball team to get a purportedly transgender teammate banned from the Mountain West Conference Championship has failed. Co-captain Brooke Slusser and her co-plaintiffs waited too long to seek an emergency court order barring the player from the tournament, which starts Wednesday, Colorado federal court judge S. Kato Crews ruled Monday. Slusser — along with former Spartan volleyball players Alyssa Sugai and Elle Patterson, San Jose State associate head coach Melissa Batie-Smoose, and eight players from four schools that have forfeited games against the Spartans over the player’s presence on the team — asked the court Nov. 15 for an emergency injunction. They had requested a court order banning the player from future games, including the championship, and that the conference’s policy allowing transgender players be rescinded. They also wanted Spartan wins that occurred via forfeit canceled, plus a recalculation of conference standings based on those requested changes. Crews said an emergency injunction “is an extraordinary remedy,” and should only be granted if clearly shown to be necessary to prevent an irreparable harm, and that if it were considered in a trial, would have a “substantial likelihood of success.” Teams started forfeiting against San Jose State in late September, the judge noted. The “delay” by Slusser and the others in filing the lawsuit and seeking the emergency order related to the tournament “weakens their arguments regarding irreparable harm,” Crews wrote. The player’s purported transgender status was revealed via news coverage this spring, and the plaintiffs “certainly had knowledge of this alleged player when the string of member institutions started forfeiting matches” in September, the judge added. The lawyer for Slusser and her co-plaintiffs filed an appeal of the order Monday shortly after it was released. The filing did not detail the grounds for appeal. This news organization is not naming the player, as they have not confirmed their status. Crews noted that no defendants in the lawsuit dispute that a transgender woman is on the Spartan team. Slusser and the others sued San Jose State officials , the conference and other defendants in Colorado federal court Nov. 13. For courts, temporary injunctions like those sought in this case are intended to “preserve the status quo” until a trial can provide a legal resolution, Crews said. Under accepted court precedent, that status quo should be “the last peaceable uncontested status existing between the parties before the dispute developed,” Crews wrote. That peaceable status, according to the judge, had existed after the conference’s transgender policy was ratified in 2022 and after the player began competing for the Spartans that year, the judge wrote. With regard to the policy, that status lasted until Slusser and the others filed their lawsuit, the judge wrote. With regard to the player, it was not until this past spring, at the earliest, that questions arose around their gender identity, Crews wrote. Granting the injunction would have altered the status quo because the player has been on the Spartan roster since 2022, and throughout the 2024 season, and the conference’s Transgender Participation Policy has been in effect since August 2022, the judge said. The request for an emergency injunction claimed federal Title IX education law prohibiting sex-based discrimination “protects women, not men who identify as women.” However, Crews wrote, court precedent, including from the U.S. Supreme Court, suggests Slusser and her co-plaintiffs “have failed to show a likelihood of success on the merits of these claims.” Crews also said that the requested injunction would have led to an “eleventh-hour shake-up” for the championship tournament. The Spartan team over the weekend secured the No. 2 seed spot in the six-team tournament, with a bye in the first round . Then they are scheduled to face the winner of a match between Utah State and Boise State — two of the five teams that have forfeited against San Jose State. Slusser earlier joined a similar lawsuit, in Georgia federal court, against the National Collegiate Athletic Association over its rules allowing certain transgender women to play women’s sports. ©2024 MediaNews Group, Inc.
