دانشمندان MIT موفق به توسعه روشی شدند که با ترکیب نانوذرات و یک تست ساده ادرار، امکان تشخیص زودهنگام سرطان ریه را فراهم می‌کند.
🔹 چطور عمل می‌کند؟
1️⃣ استنشاق نانوذرات حاوی بارکدهای DNA 2️⃣ تغییر این نانوذرات در حضور آنزیم‌های توموری و انتقال آنها به ادرار 3️⃣ تشخیص آسان با یک نوار کاغذی ساده مشابه تست بارداری
💡این روش:
✔️ کمتر تهاجمی ✔️ مقرون‌به‌صرفه ✔️ مناسب برای مناطق با منابع محدود

The news also helped traders look past another report showing decades-high inflation and shake off some of the volatility from recent sessions. The Bureau of Labor Statistics' February Consumer Price Index (CPI) this week showed another surge in prices even before Russia escalated its attacks in Ukraine. The headline CPI — soaring 7.9% over last year — underscored the sticky inflationary pressures reverberating across the U.S. economy, with everything from groceries to rents and airline fares getting more expensive for everyday consumers. That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future. For Oleksandra Tsekhanovska, head of the Hybrid Warfare Analytical Group at the Kyiv-based Ukraine Crisis Media Center, the effects are both near- and far-reaching. "The inflation fire was already hot and now with war-driven inflation added to the mix, it will grow even hotter, setting off a scramble by the world’s central banks to pull back their stimulus earlier than expected," Chris Rupkey, chief economist at FWDBONDS, wrote in an email. "A spike in inflation rates has preceded economic recessions historically and this time prices have soared to levels that once again pose a threat to growth." Friday’s performance was part of a larger shift. For the week, the Dow, S&P 500 and Nasdaq fell 2%, 2.9%, and 3.5%, respectively.
