From Nero's Poison to Turkish Jam: The Deadly Double Life of Cherry Laurel

2025-03-11

The author discovers a cherry laurel tree in their backyard, a plant whose fruits and leaves contain the deadly poison cyanide. Historically, it was used by Locusta, Nero's poisoner, to assassinate enemies. However, cherry laurel has also been used as a food flavoring; 19th-century British cooks used its leaves in puddings, resulting in child poisonings. Today, in Turkey, ripe cherry laurel fruits are made into jams and other foods. The article engagingly recounts the plant's transformation from ancient poison to modern food, warning against confusing cherry laurel with bay leaves to prevent accidental poisoning.

Mars' Middle Atmosphere: Gravity Waves Reign Supreme

A groundbreaking study reveals that unlike Earth, Mars's middle and upper atmosphere circulation is primarily driven by gravity waves (GWs), not Rossby waves. Analysis of long-term atmospheric data shows GWs facilitate rapid vertical transfer of angular momentum, significantly influencing north-south circulation. This contrasts with Earth's stratosphere, resembling the mesosphere instead. This finding necessitates refining existing Martian atmospheric models for improved climate and weather simulations, crucial for future missions. Future research will explore the impact of Martian dust storms on this dynamic, promising more accurate Martian weather forecasting.

The Layoff Lie: Why Companies Keep Doing It Despite the Evidence

From the airline industry's post-9/11 layoffs to the 2023 tech sector bloodbath, corporate downsizing has become commonplace. Yet, research consistently shows layoffs damage company culture, morale, and productivity, often failing to deliver promised financial gains and even increasing bankruptcy risk. This article traces the roots of this practice back to the 1980s, when shareholder value maximization became paramount, and aggressive CEO strategies popularized mass layoffs. The long-term consequences are overwhelmingly negative, highlighting the need for alternatives such as delaying purchases, reducing hours, or implementing furloughs.

Rethinking Bug Trackers: A Separation of Concerns

2025-03-10

After years of using various bug trackers, the author identifies a fundamental flaw in their data representation, leading to recurring frustrations. Three key issues are highlighted: a unified 'Fix Version' field conflating facts and plans; a two-tiered Status and Resolution system blurring the lines between code reality and future intentions; and the conflation of bug lists with to-do lists, creating awkwardness for non-bug tasks. The author proposes a 'separation of concerns' principle, suggesting a split into 'facts' and 'plans' tables. The facts table records objective bug information (existence, version, severity), while the plans table tracks intentions, timelines, and subjective priorities. This separation streamlines bug tracking, better accommodates different project types, and even allows for the complete omission of the plans table for projects focused solely on bug resolution.

Supercomputer Maps Molecular Blueprint for Repairing Damaged DNA

Scientists used the Summit supercomputer to simulate the pre-incision complex (PInC), a critical component in the nucleotide excision repair (NER) pathway. NER is a complex molecular mechanism that repairs damaged DNA in three stages: recognition, verification, and repair. Each stage involves different protein complexes. Researchers built a 3D model of PInC using various biophysical techniques and AlphaFold2 for structure prediction, and then used molecular dynamics simulations to reveal its dynamic properties and functional mechanisms. This research sheds light on genetic disorders related to NER, such as xeroderma pigmentosum and Cockayne syndrome, and provides crucial insights for developing novel treatments.

Agentic AI: Convenience at the Cost of Privacy?

Signal President Meredith Whittaker warned at SXSW that the burgeoning field of agentic AI, while offering convenience, poses significant privacy risks. AI agents, designed to handle tasks like booking tickets and sending messages, require access to a user's browser, credit card information, calendar, and messaging apps—essentially granting them root-level permissions. This exposes user data to cloud servers, blurring the lines between application and OS layers. Whittaker argued this "putting your brain in a jar" approach undermines security and privacy, even threatening privacy-focused apps like Signal. She urged the industry to address the potential dangers of agentic AI, cautioning against sacrificing privacy for convenience.

Slushies: A Warning for Parents of Young Children

Slushies: A Warning for Parents of Young Children

New research suggests children under eight should avoid slushies due to the potential for glycerol intoxication syndrome. The brightly colored icy drinks contain high levels of glycerol, a sugar substitute that prevents freezing. This can lead to symptoms including loss of consciousness, low blood sugar, lactic acidosis, and hypokalaemia. While glycerol is present in some foods, the concentration in slushies is significantly higher. A study examined 21 children (ages 2-7) who experienced symptoms like those described above after consuming slushies, requiring emergency treatment. Although all recovered, researchers urge caution, particularly as there's a lack of transparency regarding glycerol levels in slushies, making it difficult to determine a safe dose. The Food Standards Agency already advises against slushies for children under four and limits consumption for those aged five to ten. This new research reinforces the need for parents to avoid giving slushies to children under eight.

The Year-Long Cover-Up of the H5N1 Dairy Outbreak

The Year-Long Cover-Up of the H5N1 Dairy Outbreak

A year ago, the USDA and the dairy and cattle industries were in damage control mode regarding the H5N1 2.3.4.4b B3.13 outbreak. Initially, the virus was believed to spread exclusively through milk from lactating cows, leading to simplified control strategies. However, a new study reveals a different story: widespread transmission among both lactating and non-lactating cows, with respiratory spread likely the primary route. For a year, serological test results were suppressed, only recently being released. This exposes opacity in decision-making and a prioritization of economic interests over scientific truth. The study highlights the complexity and potential risks of H5N1, calling for more comprehensive control measures.

The internet is slowly forgetting: every year, a significant portion of web pages disappears forever. The Internet Archive (IA) stands as a crucial guardian of this digital memory, yet its survival faces increasing challenges. The author argues that while preserving everything is economically infeasible, the powerful information compression capabilities of Large Language Models (LLMs), despite inaccuracies, are better than complete loss. Models like DeepSeek V3 already offer a compressed view of the internet.

DeepEP: A High-Performance Communication Library for Mixture-of-Experts

DeepEP is a communication library designed for Mixture-of-Experts (MoE) and expert parallelism (EP), offering high-throughput and low-latency all-to-all GPU kernels (MoE dispatch and combine). It supports low-precision operations, including FP8. Optimized for the group-limited gating algorithm in DeepSeek-V3, DeepEP provides kernels for asymmetric-domain bandwidth forwarding (e.g., NVLink to RDMA). These kernels achieve high throughput, suitable for training and inference prefilling. SM (Streaming Multiprocessors) number control is also supported. For latency-sensitive inference decoding, low-latency kernels using pure RDMA minimize delays. A hook-based communication-computation overlap method is included, requiring no SM resources. The library is tested with InfiniBand and is theoretically compatible with RoCE.
