After taking a pill, the drugs it contains are distributed throughout the body, reaching the tissues and cells affected by disease and performing their intended function. However, they also enter healthy cells, where they often cause more harm than good.
Amide bonds are chemical linkages essential to biology, medicine and materials chemistry. Peptide bonds, a class of amide bonds, link amino acids to form proteins. Amide bonds are also important in medicines and polymers. Efficient synthesis of amide bonds remains a major focus in green chemistry.
Quantum photonics could be a pivotal part of future quantum technology if the right materials can be created, a new review paper has found.
Could you imagine if pagers made a comeback? Sure, your smartphone would still be your notepad-flashlight-camera-personal assistant-MP3 player-wallet-social media browser. But imagine if pagers made it so easy to do that one important thing—pinging your friends and associates—that we all brought them back into our lives, or adopted them for the first time.
Researchers often use antibodies to detect specific molecules or biological markers because they are remarkably precise at recognizing their targets. However, finding the faint signals of cancer in blood samples is a challenge even for the most reliable techniques.
Cities trying to cool sweltering streets often set broad tree canopy targets. But those targets can overlook the reality that not all shade is equally useful, and not every neighborhood has room for more trees.
Meet the Milky Way’s first microblazar
The former vice president thinks this year is when we’ll get serious about climate change
The rare fossil hints that differences in plumage may explain why some Cretaceous-era birds survived an asteroid impact but others died.
Fusion-powered space travel has long held the promise of rapid trips across the solar system: Mars in weeks, Saturn in months, Pluto in years. For decades, such possibilities have remained theoretical, like something plucked out of a science fiction novel. But several companies are now working to build practical nuclear fusion propulsion engines, with significant milestones being hit. Pulsar Fusion, a U.K.-based startup, hopes to launch a demonstration mission to space in 2027, while Princeton University and Helicity Space in the U.S. are continuing their own work on fusion drives.Richard Dinan, the CEO of Pulsar Fusion, displays the Sunbird spacecraft at the company's facility in Bletchley,...
The problem when you're buying a new pair of binoculars is that you need different specs and characteristics for different purposes, and if you don't know exactly what you need, it's easy to buy a pair that's totally wrong for you. Birdwatching requires sharp, chromatic aberration-free optics, while astronomy needs large objective lenses and tripod compatibility — and a general purpose binocular should sit somewhere in the middle. We've rounded up the best options for each usage case, based on our reviews and experience, to bring you the top models on the market.Best for everything Excellent optics for the price Celestron Regal ED 10x42 The Celestron Regal ED 10x42 are an ideal all-rounder f...
