MATHEMATICS HELPED SWIMMER WIN GOLD MEDAL AT TOKYO

In 2014, Andrew Wilson, a dual major in applied math and physics at Emory University and a walk-on swimmer, collaborated with mathematician Ken Ono to enhance his swimming performance. Ono, known for studying abstract mathematical patterns, began analyzing acceleration data from Wilson and other swimmers to identify weaknesses. This approach led to Wilson winning a national collegiate championship and eventually earning a gold medal at the 2021 Tokyo Olympics. Ono, now at the University of Virginia, continues to use mathematics to improve swimming techniques, working with UVA’s head coach Todd DeSorbo. His methods include high-definition video, accelerometers, and force paddles to analyze swimmers’ movements and optimize their performance. Ono’s data-driven approach has contributed to numerous UVA athletes becoming Olympians. His work emphasizes the importance of precise mathematical analysis in achieving peak athletic performance, despite some skepticism from traditional coaches. (Quanta)

US-CHINA RESEARCH COLLABORATIONS DECLINE DUE TO TENSIONS

Since the pandemic, China’s research collaborations with other countries, particularly the United States, have declined. An analysis by Springer Nature using InCites data showed a drop in papers co-authored by Chinese and international researchers, with a notable 6.4% decline in US-China collaborations from 2017 to 2023. The proportion of China’s articles with international co-authors fell from 26.6% in 2018 to 19.4% in 2023, despite a rise in China’s total research output. Political tensions and restrictive policies in both countries have exacerbated this decline. The US’s China Initiative, targeting espionage in research, and China’s revised counter-espionage law have fostered a climate of fear among researchers. This has led to decreased productivity and potential brain drain. Experts warn that the decline in US-China collaborations may hinder progress on global issues like climate change and pandemics, emphasizing the need for renewed international cooperation. (Science)

BRAZILIAN SCIENTISTS WARN OF OROPOUCHE VIRUS RISKS

Brazilian scientists have raised concerns about the Oropouche virus, which has been linked to potential stillbirths and neurological defects in babies born to infected mothers. A report from Brazil’s health ministry on July 12 highlighted four cases of microcephaly and one fetal death potentially associated with the virus. Although the connection is not yet confirmed, health professionals are advised to monitor pregnant women with Oropouche. The virus, transmitted by the Culicoides paraenesis midge, has surged in Brazil, with 7,044 confirmed cases in 2024, up significantly from 2023. Research at the Evandro Chagas Institute revealed antibodies in babies with microcephaly and viral genetic material in a stillborn fetus, suggesting possible vertical transmission. However, due to limitations in test quality and the need for further research, definitive links between Oropouche infection and birth defects are not yet established. Experts like Felipe Naveca and Judith Steen suggest that rising Oropouche cases and testing could uncover more complications, similar to past outbreaks of Zika. Without vaccines or treatments, Brazil’s health ministry advises preventive measures to avoid midge bites. (Science)

MILLIONS OF SEEDS RELEASED TO RESTORE FLOOD-AFFECTED AREAS

On National Forest Protection Day, July 17, an aerial operation released about 5 million seeds to restore vegetation in flood-affected areas of Rio Grande do Sul. Using two army helicopters and one from the Federal Highway Police, teams distributed seeds across the Taquari River’s slopes and banks. The seeds were in biodegradable clumps, spread by agents from the Taquari 2 military operation, IBAMA, and SEMA. The sowing included 24 native species, such as angico and jabuticabeira, along with three forage plants to stabilize the soil. The effort also involved planting seedlings. This initiative aims to repair riparian vegetation damaged by historic floods in May, which had jeopardized soil stability, potentially leading to landslides and risks to nearby communities and highways.

X203 ANTIBODY EXTENDS MICE LIFESPAN AND IMPROVES HEALTH

Biochemist Jesús Gil and cardiologist Stuart Cook report promising results from their research on the X203 antibody, which has extended the lifespan of mice by up to 25% and improved their health markers. The antibody targets interleukin 11, a protein linked to aging and inflammation. Mice treated with X203 showed better health, including less cancer and lower cholesterol. Clinical trials for similar treatments in humans are underway, showing promising safety profiles. While enthusiasm is high, caution remains. Biologist Rafael de Cabo emphasizes the need for broader studies across various mouse strains to validate these findings. Current aging research includes interventions like rapamycin and metformin, but concrete evidence for their effectiveness in humans is still lacking. For now, conventional wisdom on extending healthy life focuses on calorie restriction and regular exercise. (El Pais)

RESEARCH BIAS IN LONELINESS STUDIES IGNORES FEMALE SUBJECTS

The pursuit of extending human lifespan is a booming industry, but its research is skewed heavily towards male subjects. Dr. Steven Austad highlights a significant issue: most longevity drugs are tested primarily on male mice, neglecting the substantial sex differences that exist. As a result, drugs effective in males often fail in females, with even fewer studies addressing the effects on mothers. For instance, a low methionine diet that extended life in male rats had adverse effects on females, demonstrating the oversight in including both sexes in research. Jennifer Garrison criticizes the longstanding bias in biomedical research, where the male body has been the default subject, overlooking crucial differences in female physiology, particularly related to reproductive cycles and childbirth. Austad calls for increased focus on understanding these sex differences to ensure that longevity treatments benefit all genders, emphasizing the need for scientific reform to address this disparity.
