A worldwide quest is under way to find new treatments to stop, slow or even prevent Alzheimer's disease. Because new drugs take years to produce from concept to market — and because drugs that seem promising in early-stage studies may not work as hoped in large-scale trials — it is critical that Alzheimer's and other dementia research continues to accelerate. To advance this effort, the Alzheimer's Association funds researchers looking at new treatment strategies and advocates for more federal funding of Alzheimer's research. Currently, there are five Alzheimer's drugs approved by the U. Food and Drug Administration FDA that treat the symptoms of Alzheimer's disease — temporarily helping memory and thinking problems — with a sixth drug available globally. However, these medications do not treat the underlying causes of the disease or slow its progression. These changes offer potential targets for new drugs to slow or stop the progress of the disease.

For years, the scientific community has been pursuing the holy grail of a complete cure for HIV , the infection linked to the deadly AIDS disease which has 35 million people worldwide since its discovery 4 decades—and to this day afflicts nearly 38 million. A great number of scientists conducting research on an HIV vaccine cure, along with scientists toiling on treatments for many other diseases, have been repurposed and put to work researching promising therapies and vaccine candidates for the novel coronavirus.

June The world has been in pandemic mode for a year and a half. The virus continues to spread at a slow burn; intermittent lockdowns are the new normal. An approved vaccine offers six months of protection, but international deal-making has slowed its distribution. An estimated million people have been infected worldwide, and 1. Around the world, epidemiologists are constructing short- and long-term projections as a way to prepare for, and potentially mitigate, the spread and impact of SARS-CoV-2, the virus that causes COVID Although their forecasts and timelines vary, modellers agree on two things: COVID is here to stay, and the future depends on a lot of unknowns, including whether people develop lasting immunity to the virus, whether seasonality affects its spread, and — perhaps most importantly — the choices made by governments and individuals. Recent models and evidence from successful lockdowns suggest that behavioural changes can reduce the spread of COVID if most, but not necessarily all, people comply. Last week, the number of confirmed COVID infections passed 15 million globally, with around , deaths. Lockdowns are easing in many countries, leading some people to assume that the pandemic is ending, says Yonatan Grad, an epidemiologist at the Harvard T.
