Promise of Victory Over H.I.V. Fades as U.S. Withdraws Support
This was supposed to be a breakthrough year in the 44-year-long struggle against H.I.V.
Decades of research and investment produced new approaches to vaccines that were going into their first significant clinical trials.
The hunt for a cure was homing in on key mechanisms to block the virus, which can lurk dormant and near-untraceable in the body for years.
Most critically, a breakthrough preventive drug, lenacapavir, a twice-yearly injection that offers total protection from H.I.V., was to be rapidly rolled out across eastern and southern Africa. The main target: young women. About 300,000 of them were newly infected with the virus last year — half of all new infections worldwide.
Every one of these plans has been derailed by the Trump administration's slashing of foreign assistance.
There is more potential than ever before to end the H.I.V. epidemic, scientists and public health experts say. But now, H.I.V. programs across Africa are scrambling to procure drugs that the United States once supplied, replace lost nurses and lab technicians, and restart shuttered programs to prevent new infections.
'We imagined we would be in a different world right now,' said Dr. Leila Mansoor, a senior research scientist at the Centre for the AIDS Program of Research in Durban, South Africa. She had planned to spend 2025 analyzing data from one H.I.V. prevention trial, preparing for another and tracking how lenacapavir was transforming the epidemic — alongside colleagues testing new vaccines and cure strategies.

Vaccine panel appointed by RFK Jr. loses member before first meeting
ATLANTA — The influential federal vaccine panel appointed by Health Secretary Robert F. Kennedy Jr. two weeks ago lost one of its members hours before it was set to meet for the first time Wednesday. 'Dr. Michael Ross decided to withdraw from [the Advisory Committee on Immunization Practices] during the financial holdings review required of members before they can start work on the committee,' said Andrew Nixon, a spokesman for Kennedy's health department. 'The sacrifice to serve on ACIP varies from member to member, and we appreciate Dr. Ross's willingness to go through this rigorous process. We would have benefited from his service and expertise on this committee. The meeting will go as planned and there will be a quorum.'

Earth Is Pulsing Beneath Africa Where The Crust Is Being Torn Apart
A deep, rhythmic pulse has been found surging like a heartbeat deep under Africa. At the Afar triple junction under Ethiopia, where three tectonic plates meet, molten magma pounds the planet's crust from below, scientists have discovered. There, the continent is slowly being torn asunder in the early formation stages of a new ocean basin. By sampling the chemical signatures of volcanoes around this region, a team led by geologist Emma Watts of Swansea University in the UK hoped to learn more about this wild process. "We found that the mantle beneath Afar is not uniform or stationary – it pulses, and these pulses carry distinct chemical signatures," says Watts, who was at the University of Southampton in the UK when the research was conducted. "These ascending pulses of partially molten mantle are channeled by the rifting plates above. That's important for how we think about the interaction between Earth's interior and its surface." Related: Our planet's surface is in a constant state of renovation. The tectonic plates into which the planetary crust is divided aren't fixed in position, but shift and collide and even slip underneath one another. The places at which they meet are usually hotspots of geological evolution, quite literally, rampant with volcanic activity that is reshaping the surface from below. The Afar junction is the point at which the Arabian, Nubian, and Somalian plates meet, each departing in their own directions to leave a widening gap under the Afar Triangle. Eventually, the crust will become so thin here that the surface will drop below sea level, creating a new ocean basin off the Red Sea. Scientists suspect that mantle upwelling is playing a role in this continental breakup process, but our understanding of how it works is limited. We can't exactly just dig down to have a close look, so Watts and her colleagues went for the next best thing: looking at material that has been disgorged onto Earth's surface from the mantle by way of volcano. They collected 130 samples of volcanic rock from around the Afar region and the Main Ethiopian Rift, and conducted chemical analyses. They used these analyses combined with existing data to conduct advanced modeling to understand what's going on with the activity under the Triangle. The results showed distinct chemical bands or stripes that repeat across the rift system, delivered by a single, asymmetrical plume of material shaped by its environment and pushing upwards from the mantle. "The chemical striping suggests the plume is pulsing, like a heartbeat," says geologist Tom Gernon of the University of Southampton in the UK. "These pulses appear to behave differently depending on the thickness of the plate, and how fast it's pulling apart. In faster-spreading rifts like the Red Sea, the pulses travel more efficiently and regularly like a pulse through a narrow artery." If the team's model is correct, it suggests that mantle plumes and upwellings can be shaped by the dynamics of the tectonic plates above them – a finding that could be used to inform future research into the activity that is continually remodeling our planet. "We have found that the evolution of deep mantle upwellings is intimately tied to the motion of the plates above. This has profound implications for how we interpret surface volcanism, earthquake activity, and the process of continental breakup," says geophysicist Derek Keir of the University of Southampton and the University of Florence in Italy. "The work shows that deep mantle upwellings can flow beneath the base of tectonic plates and help to focus volcanic activity to where the tectonic plate is thinnest. Follow-on research includes understanding how and at what rate mantle flow occurs beneath plates." The research has been published in Nature Geoscience.

Innovodigm, AuraML, Sthyr Energy Secure Early-Stage Funding for Growth
The below Indian startups have announced their latest funding rounds. You're reading Entrepreneur India, an international franchise of Entrepreneur Media. IAN Leads INR 5.5 Cr Funding in Med-tech Innovodigm Kolkata-based med-tech startup Innovodigm has raised INR 5.5 crore in a seed funding round led by the IAN Group, which contributed INR 4.5 crore, with the remainder from PadUp Ventures. The funds will be deployed toward process optimization, infrastructure scaling, and team expansion in preparation for third-party preclinical validation and upcoming clinical trials. Founded in 2020 by Jhimli Manna and Ayan Chatterjee, Innovodigm is a deep-tech spin-off from IIT Kharagpur's Microelectronics and MEMS Lab, and is developing India's first Microneedle Array Patch (MAP) — a skin-dissolvable, painless, and waste-free vaccine delivery system. "Our MAP platform reflects India's ability to lead in affordable, scalable vaccine delivery," said Dr Manna, CEO, adding that the IAN support will help take the technology from lab to field. Padmaja Ruparel, Co-founder, IAN Group, said, "Innovodigm has the potential to fundamentally alter the vaccine distribution landscape, particularly in areas where cold-chain logistics and access are significant obstacles. The microneedle platform, in our opinion, has the potential to enable last-mile vaccination and lessen the worldwide medical waste load." The platform has earned top honors at the Nano Electronics Showcase 2025 and G20 Summit. With clinical trials set for next year, Innovodigm plans to adapt its patch for vaccines like measles, hepatitis, flu, and COVID-19, targeting underserved regions globally.
