Today’s Exhibit of the Day? It’s one of the largest amethyst geodes in the world! At about 13 ft (4 m) tall and 9,000 lbs (4,082 kg), this giant weighs about as much as three compact cars. It was born when molten magma poured from the Earth’s crust some 135 million years ago. While its dazzling purple crystals might catch your eye, this geode would have originally been composed of colorless quartz—its distinctive amethyst color deriving from millenia of natural radiation, heat, and trace contaminants.
You can spot this geode, and other sparkly specimens, in the Museum’s Mignone Halls of Gems and Minerals. We're open daily from 10 am-5:30 pm! Plan your visit.

With the type of co-design used in this study — hardware and software developed in tandem — nanowire networks may ultimately serve a complementary role alongside silicon-based electronic devices. Brain-like memory and processing embedded in physical systems capable of continuous adapting and learning may be particularly well-suited to so-called “edge computing,” which processes complex data on the spot without requiring communication with far-off servers.
Superconductivity is the property of certain materials that can conduct electric currents with no resistance. This quantum phenomenon is still shrouded in mystery, and until now has been limited to very low temperatures. Yet all this could soon change.
Awwweeee 🥹💖💖💖 I am so glad I met you!
a quick “why is my life so bad” checklist
how’s your sleep schedule
have you eaten or drank anything besides sugar and caffeine
how long have you been sitting in one spot
have you gone out in public recently
have you taken a shower/brushed your teeth/groomed yourself properly
have you spent time doing an activity that doesn’t involve a screen
etc
We need to get a little uncomfortable for a minute. But it's ok. You have to be uncomfortable in order to grow.
You're going to fail. You're going to disappoint people and yourself. You're going to have moments where you're so overwhelmed that you're curled in a ball crying and frustrated. You're going to miss important milestones. You're going to drop the ball so many times things seem impossible. You're going to fail. You're going to be mean. You're going to be a bad person at points. It's life. It happens. You just need to understand that it happens. And on those days where you want to dissappear and never be seen again because everything is too much, your brain is going to amplify all these faults and failures and make them seem worse.
Babe. We all go through this. We ALL fail. We ALL make awful choices and fuck people and ourselves over. We ALL will have moments where we are the villains. Where we completely fail a lot of people in our lives due to bad decisions. It will happen. Probably multiple times. What matters is that you recognize these things and make appropriate changes in your life to help make sure that next time isn't as bad. Maybe start learning time management so you're not stressed constantly and blowing up on everyone. Maybe find a healthy outlet like painting or the gym or cooking. Find small, simple joys to make life better. It's going to suck. You're going to be the bad guy. But that's not your entire life.
It's uncomfortable and hard to sit with. Sometimes things are your fault. Sometimes you make bad choices and they fuck your life up and fuck others over at the same time. It happens. You can't change the past, but you have the power to change your future. You can change your future. Talk to people. Find yourself outlets. Learn skills. Things get better, but they only do so if you put the effort for them to do so. I love you. You're trying. And that's all you can do. And one day you'll slip backwards and feel so defeated but when that happens, you'll have many tools to help you get even further. I promise babe everything will be ok.
A crucial piece of evidence in support of a long-standing hypothesis on planet formation has been observed by the James Webb Space Telescope (JWST), meaning astronomers are confident they've got a part of the cosmic process right. JWST data processed by an international team of researchers backs up the theory of 'icy pebble drift', which is thought to be vital in bringing together the dust and rocks that eventually turn into planets like our own. Simply put, icy pebble drift works like this: as tiny, ice-covered bits of material bump together in the outer reaches of a young protoplanetary disk they lose momentum, allowing them to fall towards the star into a warmer zone where their frozen coating sublimates. It's from this ring of fine debris and water vapor that rocky planets form, effectively serving as a delivery service of building materials right across a newborn solar system.
