Google Research revealed a surprisingly simple technique to boost LLM accuracy. Repeating the input prompt can increase performance by up to 76%. The paper, released last month, detailed the findings.
Researchers discovered that duplicating prompts significantly improved results on tasks not requiring complex reasoning. This method works across major models like Gemini, GPT-4o, Claude, and DeepSeek. The study challenges complex prompting strategies developed over the past few years.
The immediate impact is a potential simplification of AI optimization. Engineers may be able to achieve better results with less complex methods. The AI community is now evaluating the implications of this discovery.
Previously, complex methods like "Chain of Thought" and multi-shot prompting were considered essential. This new research suggests a more straightforward approach may be sufficient for many tasks.
Further research will explore the limits of prompt repetition. Future studies may investigate its effectiveness on more complex reasoning tasks. The findings could reshape LLM development strategies.

Analysis of 8,000-year-old Mesopotamian pottery shards reveals surprisingly early evidence of structured mathematical thinking, predating the first written numbers by millennia. This discovery highlights the cognitive capabilities of ancient societies and prompts further investigation into the origins and evolution of mathematical reasoning, potentially influencing how AI models are trained to understand abstract concepts.
Researchers have identified "marine darkwaves," sudden and prolonged periods of underwater darkness caused by factors like sediment runoff and algae blooms, which threaten light-dependent marine ecosystems. This new framework helps scientists understand and compare these blackout events, highlighting the increasing risk to kelp forests and seagrass meadows due to declining water clarity. The study underscores the importance of understanding how these events impact marine life and the broader implications for coastal ecosystem health.
Research indicates that wildfires in Arctic Alaska have reached a 3,000-year high due to climate change, with warming temperatures drying the soil and promoting shrub growth, creating conditions for intense fires. Analysis of peat cores and satellite data confirms a significant surge in fire activity since the mid-20th century, signaling a shift towards a more hazardous fire regime in the Arctic with potential impacts on ecosystems and global climate patterns.
Researchers have identified a mechanism by which some statins induce muscle pain: by binding to a muscle protein and causing calcium leakage within cells. This discovery offers a potential pathway for developing new statins or treatments that mitigate muscle-related side effects, improving patient adherence and cardiovascular health.
A new form of neonatal diabetes has been identified, stemming from mutations in the TMEM167A gene that impair insulin production. This discovery, utilizing advanced DNA sequencing and stem cell models, not only clarifies the genetic origins of early-onset diabetes but also establishes a link between diabetes and neurological conditions, potentially reshaping our understanding and treatment of the disease.
Senate Republicans have blocked a resolution that would have mandated congressional approval for military actions in Venezuela, reversing initial bipartisan support after White House assurances. The defeat, achieved with a 51-50 vote and the Vice President's tie-breaking vote, followed President Trump's criticism of Republicans who initially supported the measure, which was prompted by the U.S. capture of Venezuelan President Nicolás Maduro. The resolution aimed to reassert congressional authority over military interventions, reflecting differing views on executive power in foreign policy.
Facing bipartisan backlash, the Trump administration has reversed its decision to cut over $2 billion in funding for mental health and addiction programs, a move that had initially shocked healthcare providers nationwide. The restored grants will ensure continued access to vital services, preventing potential disruptions in care for vulnerable populations struggling with mental health and substance use disorders. Experts emphasize that consistent funding is crucial for maintaining effective treatment and support systems during a time of increasing need.
The FBI searched a Washington Post reporter's home as part of a leak investigation concerning a Pentagon contractor suspected of mishandling classified information. While the reporter and the newspaper are not considered targets, the Justice Department's action is raising concerns about press freedom and the protection of sources, according to the Post's executive editor. The search is considered an escalation in the government's efforts to control leaks.
In Minneapolis, a DHS/ICE agent shot a Venezuelan man in the leg during an attempted arrest after the man fled a traffic stop and allegedly assaulted the officer. According to DHS, the agent was also attacked by two other individuals with a snow shovel and broom handle, prompting the use of force; the incident follows a prior fatal shooting by an ICE agent in the same city just a week prior. The injured man was hospitalized with non-life-threatening injuries, raising concerns about ICE tactics and community relations.
