The Nobel medicine prize has been awarded to American psychiatrist and neurologist Karl Deisseroth and his German colleagues, Peter Hegemann and Georg Nagel, for their pioneering work in the field of optogenetics. This scientific method enables researchers to understand how specific cell types contribute to various behaviors, including movement, addiction, fear, and learning. The Nobel Assembly highlighted that the field may one day lead to significant treatments for sensory and neurological disorders, such as epilepsy and Parkinson's disease.
According to the Nobel Assembly, optogenetics has fundamentally altered the scientific understanding of the brain. By using this method, researchers have been able to reveal neural circuits governing specific feelings, memories, and behaviors relevant to psychiatric and neurological disorders. In the realm of clinical medicine, researchers are currently utilizing the method in attempts to restore sight in individuals with visual impairment. The Nobel Assembly stated that every day brings new discoveries, helping to solve one of humanity's great mysteries regarding how the brain works.
The laureates will receive their prize—a diploma, a gold medal, and a $1.2-million cheque—from King Carl XVI Gustaf at a formal ceremony in Stockholm on December 10th. This date marks the anniversary of the death in 1896 of the prize's creator, the scientist Alfred Nobel. Last year, the medicine prize was awarded to Mary Brunkow and Fred Ramsdell of the United States and Japan's Shimon Sakaguchi for their research into how the immune system is kept in check by identifying its "security guards."
The Nobel season continues with the announcement of the physics prize on Tuesday. Physicists Sir John Pendry of Britain and David Smith of the US, who pioneered the concept of the "invisibility cloak," have been viewed as possible winners for years. They demonstrated that engineered metamaterials could bend electromagnetic waves around an object, effectively concealing it from view. The chemistry prize is scheduled for Wednesday, followed by the literature prize on Thursday. For the literature award, some pundits suggest the Swedish Academy might select a woman writer, potentially from Central or Latin America, with literary critic Lina Kalmteg noting that Argentine author Samanta Schweblin, 48, could be a candidate. Other names frequently mentioned in speculation include Antiguan-American author Jamaica Kincaid, Chinese writer Can Xue, Australian authors Gerald Murnane and Alexis Wright, US writer Thomas Pynchon, and Mexican writer Cristina Rivera Garza.
The Nobel Peace Prize, the only award presented in Oslo, is scheduled for Friday. Following the controversy surrounding last year's winner, Venezuelan opposition leader Maria Corina Machado, experts suggest the jury might choose a laureate who enjoys broad consensus. Kristian Berg Harpviken, secretary of the Nobel committee, noted that there is always significant lobbying and potential pressure exerted on the committee. Potential candidates this year include a joint prize for Save the Children and Ukrainian children's rights activist Mykola Kuleba, Sudan's Emergency Response Rooms (ERR), and the Committee to Protect Journalists (CPJ) following the deadliest year on record for the profession in 2025. The Nobel season will conclude with the economics prize on October 12th.
