Trump to impose $100,000 fee per year for H-1B visas, in blow to tech The Trump administration said on Friday it would ask companies to pay $100,000 per year for H-1B worker visas, prompting some big tech companies to warn visa holders to stay in the U.S. or quickly return.

I have to keep this deliberately vague, but this is a total disaster for academic research.

And imposing it so suddenly is just cruel. I’ve got friends scrambling to get back to the US before midnight tonight. Do you know how hard that is to do on 36 hours of notice?

Optimising testing and control strategies in the early stages of infectious disease outbreaks

Supervisors: Dr Emily Nixon, Professor Christl Donnelly, Dr Richard Vipond, Dr Emily Adams, Dr Chris Overton.


Subject area: Mathematics

Stipend Amount: Funded studentship

Duration: 3.5 years

Application deadline: 07 July 2025
Start date: 01 October 2025

Optimising testing and control strategies in the early stages of infectious disease outbreaks Supervisors: Dr Emily Nixon, Professor Christl Donnelly, Dr Richard Vipond, Dr Emily Adams, Dr Chris Overton. Subject area: Mathematics Stipend Amount: Funded studentship Study mode: Full-time Duration: 3.5 years Application deadline: 07 July 2025 Start date: 01 October 2025

Overview
Develop models to help make decisions early in a major disease outbreak when availability of new tests is limited, on where and how best to use them for maximum impact in controlling spread, e.g. in low versus high areas of transmission, in hospitals or in the community. These will depend on the pathogen type, its mode of transmission, reproduction number, etc.

About this opportunity
In the early stages of a major disease outbreak, the availability of suitable diagnostic tests is often limited, however, timely interventions are critical for controlling the spread of disease. In this PhD, you will develop mechanistic and statistical models to investigate the effectiveness of various diagnostic test deployment strategies for emerging and zoonotic diseases which are at risk of causing large outbreaks, such as respiratory viruses (Influenza, SARS-CoV-2, Respiratory syncytial virus), vector-borne diseases (Dengue, Tick-borne encephalitis) or viral haemorrhagic fevers (Nipah, Lassa fever and Crimean-Congo haemorrhagic fever). You will investigate the effectiveness of targeting use of tests in different settings, for example in areas of high versus low transmission, or in hospitals versus the community. The optimum strategy for diagnostic test deployment will vary depending on prevalence of disease, the sensitivity and specificity of the tests and the time it takes to receive and act on results. In addition, variation between pathogens, for example, in their mode of transmission, reproduction number and incubation period, will influence which strategy is the most effective in controlling the impact of the outbreak. These insights will inform stockpiling strategies of medical countermeasures for pandemic preparedness and in the event of a major outbreak, can be used and adapted to help inform decision making.

RFK Jr has worked for more than a decade to sow distrust in vaccines. Despite his efforts, the vast majority of Americans still support vaccines and follow federal guidance. Secretary Kennedy’s decision to remove ACIP members is another act in his crusade to prevent Americans from getting vaccines.

NIH grant cuts will axe clinical trials abroad β€” and could leave thousands without care US agency’s new policy could abruptly end studies of infectious diseases and cancer, leaving researchers scrambling for funds.

Researcher Amita Gupta has spent more than a decade planning and running a $70-million trial to study a new tuberculosis drug, enrolling ~6,000 participants in 13 countries. It might all have been for nothing.

That's because a new NIH policy has abruptly cut off billions to trials abroad. πŸ§ͺ
