U.S. LAWMAKERS RAISE ALARM OVER CHINA BIOTECH THREATS.
U.S. lawmakers are voicing concerns about America’s ability to compete with China in the biotechnology sector, emphasizing the potential threats to national security and commercial interests. As the rivalry between the two nations extends into biotechnology, there are warnings that excluding Chinese companies could harm the U.S. Biotechnology holds promise for groundbreaking advancements in medicine, agriculture, and materials. However, proposed legislation in both the House and Senate aims to restrict “foreign adversary biotech companies of concern,” specifically naming four Chinese-owned firms, raising criticism from the Chinese Embassy for alleged ideological bias. The debate highlights the broader tension in the U.S.-China relationship, affected by trade, cybersecurity, and other issues. Critics of the legislation fear it may hinder scientific progress, while supporters argue it’s essential for protecting U.S. interests and data security. The bills reflect the strategic importance both countries place on biotechnology for economic growth and national security, with both the U.S. and China investing heavily in the sector. Concerns revolve around transparency, unfair competition, and the potential misuse of genomic data by Chinese entities, underscoring the complex interplay between global scientific collaboration and geopolitical rivalry.

SENATOR ALLEGES DANGEROUS U.S.-CHINA AVIAN INFLUENZA COLLABORATION.
A U.S. Senator, Joni Ernst, has raised concerns about a U.S.-Chinese research collaboration on avian influenza, suggesting it involves dangerous “gain-of-function” experiments that could lead to pandemics. However, the U.S. Department of Agriculture (USDA), which funds the project, clarified that their funding only supports U.S.-based research, not foreign partners, and criticized the misinformation. The collaboration aims to understand avian influenza evolution, focusing on the transmission from wild birds to poultry rather than creating more transmissible viruses. The USDA emphasized that funding decisions were made before the current administration and suggested direct communication for any concerns. The Chinese and UK researchers involved also refute the concerns, highlighting the collaboration’s goal of controlling global disease transmission without any financial or material exchanges between countries. Critics of gain-of-function research argue for intensive review of experiments potentially creating more dangerous viruses, while project researchers assure that all work is conducted under strict biosecurity and containment protocols.

ALL OF US PROGRAM UNVEILS MAJOR GENETIC DISCOVERIES.
The All of Us program, managed by the US National Institutes of Health, is enhancing healthcare research by focusing on the genomes and health profiles of underrepresented groups. With analyses of up to 245,000 genomes, the program has discovered over 275 million new genetic markers, including nearly 150 linked to type 2 diabetes. This initiative addresses the critical lack of diversity in genetic research, where previously 78% of genomic study participants were of European descent. The All of Us program, which aims to collect detailed health profiles for one million U.S. residents by 2026, has enrolled 413,000 participants, 46% of whom are from minority groups. This data set, significantly enriched with genomes from African American, Hispanic, and Latin American individuals, provides a valuable resource for understanding diseases and developing targeted treatments. Early results include identifying genetic markers for type 2 diabetes and variations in pathogenic variants across different ancestries, highlighting the importance of including diverse genomes in research to improve healthcare outcomes for all populations.

PARENT’S DESPERATE QUEST LEADS TO HOPE IN GENE THERAPY.
On January 8, 2020, a parent received devastating news about their 7-month-old son, Eliot, diagnosed with Duchenne muscular dystrophy (D.M.D.), a fatal neuromuscular disease affecting boys. This story unfolds against the backdrop of a Los Angeles winter, marking a profound, life-changing moment. D.M.D. leads to progressive muscle degeneration due to a lack of dystrophin, with no cure available, only symptom management. In a quest for hope, the parent contacted Dr. Jerry Mendell, who developed an experimental gene therapy, Elevidys, offering potential to slow or halt the disease’s progression. Despite challenges and ongoing clinical trials, the FDA granted accelerated approval for Elevidys for 4- and 5-year-olds, contingent on evidence of improved motor function. Eliot’s treatment brought miraculous improvements, highlighting the therapy’s transformative potential. However, the path to broader FDA approval faces hurdles, including debates over clinical trial results and the high cost of gene therapies, which averages $1 million to $2 million, with Elevidys costing $3.2 million. The narrative underscores the broader implications for gene therapy access, regulatory flexibility, and the need for insurance coverage, advocating for a future where all affected children have the chance to live fuller lives.

EPA FINDS TOXIC PFAS IN DRINKING WATER ACROSS USA.
Recent testing by the Environmental Protection Agency (EPA) has revealed that approximately 70 million Americans are exposed to toxic PFAS chemicals in their drinking water. This figure is based on tests covering only one-third of the nation’s public water systems, suggesting that the actual number of affected individuals could exceed 200 million, or about 60% of the U.S. population, once all systems are tested. This estimate does not account for those using private wells, estimated at 8 million people. The EPA’s ongoing national assessment marks the first comprehensive effort to gauge the scale of PFAS contamination in U.S. drinking water. PFAS, a group of over 15,000 compounds used in various industries for their resistance properties, are linked to several serious health issues due to their persistence in the environment and inability to naturally degrade. The EPA plans further testing and is moving to finalize drinking water limits for six PFAS compounds, highlighting the urgent need for regulatory action to address this widespread pollution. The findings underscore the prevalence of PFAS, particularly PFOA and PFOS, at levels above proposed limits, prompting the necessity for utilities to adopt advanced filtration technologies, supported by significant federal funding and legal settlements from chemical manufacturers.

NASA TELESCOPES UNRAVEL MYSTERIES OF FAST RADIO BURSTS.
NASA’s X-ray telescopes, NICER and NuSTAR, have provided insights into the phenomenon of fast radio bursts (FRBs) by observing a dead star, specifically a magnetar named SGR 1935+2154, within our galaxy. This observation marks a significant step towards understanding the origins of these mysterious bursts, which release immense energy in a fraction of a second. The study, published in Nature, focused on the magnetar’s behavior before and after emitting a fast radio burst in October 2022, noting unusual rapid changes in its spin speed. Magnetars, a type of neutron star, are incredibly dense and have strong gravitational forces, making their surfaces volatile and capable of emitting high-energy light, including X-rays and gamma rays. The research suggests that a glitch in the magnetar’s surface, possibly caused by internal superfluid and crust interactions, could lead to the conditions necessary for producing an FRB. However, despite this observation, the exact mechanisms behind FRBs remain unclear, highlighting the need for further data to solve the mystery of their origins. (NASA)
VERY LARGE TELESCOPE SPOTS MOST LUMINOUS QUASAR EVER.
The Very Large Telescope in Chile has observed the most luminous object ever detected in the universe, a quasar named J0529-4351. This quasar, with a black hole at its core 17 billion times the mass of the Sun, consumes the equivalent of one Sun’s mass daily. Despite being recorded in data years ago, its significance was only recently acknowledged. Emitting energy over 500 trillion times more luminous than the Sun, the quasar’s light, which has traveled 12 billion years to reach Earth, illuminates the extreme processes at the heart of active galaxies. The energy originates from a vast accretion disc around the black hole, spanning seven light-years in diameter, believed to be the largest of its kind in the universe. This discovery highlights the quasar’s extraordinary characteristics and its contribution to understanding galactic cores powered by supermassive black holes. (BBC)
