Scientists at EPFL used mass spectrometry imaging (MALDI-MSI) alongside liquid chromatography-mass spectrometry and single-nucleus RNA sequencing to catalog lipid molecules across coronal brain sections from adult mice. The study included comparisons between male and female mice, as well as pregnant females, sampling six specific brain regions to examine how lipid composition varies by sex and physiological state.
Walmart is selling MSI's Gaming Trio GeForce RTX 5090 for $4,299 as part of its GeForce Week promotion, a price well below the $8,000+ third-party listings currently common for the card. The RTX 5090 remains Nvidia's top gaming GPU, still selling far above its original $1,999 MSRP due to scarce supply and demand from AI workloads.
Newegg is selling the MSI Spatium M461 2TB PCIe 4.0 SSD for $299.99 using promo code SSD73852, working out to about 10 cents per gigabyte. The drive uses a Phison E21T controller with 3D NAND and NVMe 1.4 support, delivering sequential speeds up to 5,000/4,200 MBps read/write, backed by a five-year warranty and 900 TBW endurance rating.
Newegg is offering a two-item combo pairing AMD's Ryzen 7 9800X3D gaming CPU with an MSI MAG X870E Gaming Max Wifi motherboard for $578.99, down from $727.99. The deal also throws in a free Cooler Master Elite Liquid 240 AIO cooler worth $80, and the discount effectively makes this the cheapest way to get the 9800X3D.
Newegg is selling the MSI Codex R2 desktop for $1,429, a $270 discount, bundling an Nvidia GeForce RTX 5060 GPU, an Intel Core i5-14400F 10-core CPU, 32GB of DDR5 RAM, and a 2TB SSD. The build targets smooth 1080p gaming, with some headroom for 1440p when DLSS multi-frame generation is enabled.
MSI (Message Signaled Interrupts) lets a device like a GPU notify the CPU of an interrupt by writing to a memory address rather than fighting for space on a shared physical hardware line. Windows 10 and 11 default to MSI-X, an expanded version introduced with PCI 3.0 in 2010, whenever a device supports it. This approach labels each interrupt with its source, avoiding the collisions that can occur on crowded shared IRQ lines.
A Reddit user on r/pcmasterrace posted photos of two abandoned crypto mining rigs found in a basement, containing a dozen Zotac RTX 3070 graphics cards along with DDR4 memory, SSDs, power supplies and MSI Z390 motherboards. The rigs had been used for Ethereum mining during the pandemic and sat unused after home mining stopped being profitable, with the owner giving them away once asked.
Newegg is offering a high-end PC parts bundle combining AMD's Ryzen 9 9950X3D2 CPU, an 8TB Samsung 9100 Pro SSD, an MSI X870E Gaming Plus WiFi motherboard, and 32GB of V-Color DDR5-6000 memory for $2,999, down from a combined retail price of $4,288. The deal also throws in a free Cooler Master 240mm AIO cooler and a copy of Onimusha with qualifying AMD purchases. Buyers still need to add a case, power supply, and graphics card to complete the build.
Walmart is offering the MSI Cyborg 15 gaming laptop for $1,049, a $250 discount from its regular price.

MSI has launched the MEG CoreLiquid E15 360, a flagship all-in-one liquid cooler distinguished by a large curved 6.67-inch AMOLED display and a black-and-gold design. Tom's Hardware testing found it delivers top-tier thermal performance, handling over 265W of heat from AMD's Ryzen 9 9950X3D, but its $399.99 price places it well above typical budget cooling options.
Walmart is selling the MSI GeForce RTX 5060 Ti 16G Shadow 2X OC Plus for $569.99, roughly $200 cheaper than comparable listings at Amazon, Newegg, and Best Buy. The compact dual-fan card runs on a single 6+2 PCIe power connector, draws 180W, and pairs 16GB of GDDR7 memory with clock speeds up to 2,646 MHz boost.
