An engineering student expands her focus

Danielle Grey-Stewart, a senior majoring in materials science and engineering, is a fierce believer that public service and engineering go hand in hand. She aspires to be a leader in equitable science policy and plans on using her time at Oxford University, where she will be studying next year as a Rhodes Scholar, to study nature, society, and environmental governance. Despite her interest in public service, Grey-Stewart didn’t always see policy as a future career route. A passion for……

3 Questions: Phillip Sharp on the discoveries...

Some of the most promising vaccines developed to combat Covid-19 rely on messenger RNA (mRNA) — a template cells use to carry genetic instructions for producing proteins. The mRNA vaccines take advantage of this cellular process to make proteins that then trigger an immune response that targets SARS-CoV-2, the virus that causes Covid-19. Compared to other types of vaccines, recently developed technologies allow mRNA vaccines to be rapidly created and deployed on a large-scale — crucial aspects in the……

Explained: Why RNA vaccines for Covid-19 raced...

Developing and testing a new vaccine typically takes at least 12 to 18 months. However, just over 10 months after the genetic sequence of the SARS-CoV-2 virus was published, two pharmaceutical companies applied for FDA emergency use authorization of vaccines that appear to be highly effective against the virus. Both vaccines are made from messenger RNA, the molecule that cells naturally use to carry DNA’s instructions to cells’ protein-building machinery. A vaccine based on mRNA has never been approved……

AP sources: Phillies hire Dombrowski to lead...

PHILADELPHIA (AP) — The Philadelphia Phillies have hired longtime baseball executive Dave Dombrowski as president of baseball operations, according to two people familiar with the decision. The people spoke to The Associated Press on condition of anonymity Thursday night because the team hadn’t announced the move. An official announcement is expected Friday, according to one of the people. Andy MacPhail is the Phillies’ current president and has planned to retire after the 2021 season. He said in October he…

This 19th-Century Cocktail Still Fights Cold Nights...

It’s not often one needs to make a batter for a cocktail, but so it is with the Tom and Jerry, a Christmas party staple in the American Midwest. The drink begins with a frothy batter of separately beaten egg whites and yolks folded together and mixed with sugar and warm spices. When served as a party punch, the sweet batter is often ladled out of special Tom and Jerry punch bowls into matching cocktail mugs, along with hot……

Cultural Heritage Is Caught Up in the...

After being photographed with a cross in one hand and an automatic rifle in the other, Father Hovhannes became a viral sensation in Armenia. He says he never intended to become a symbol of defiance during the recent war over Nagorno-Karabakh, the region within Azerbaijan that has attempted to break away and declare itself the “Republic of Artsakh,” with the support of the Armenian government but no other forms of international recognition. “I was showing that we need both……

Knight Science Journalism Program at MIT launches...

The Knight Science Journalism (KSJ) Program at MIT has announced the publication of a new digital handbook for science editors, offered without cost to journalists around the world, and a new fact-checking site that includes a searchable database of fact-checkers and a free teaching module for university students. Both of these pioneering projects are part of a redesign of KSJ’s home website and can be found under the resources tab on the home page. Other updates include a pictorial……

SMART researchers use lysins to selectively target...

Researchers from the Antimicrobial Resistance (AMR) Interdisciplinary Research Group (IRG) at Singapore-MIT Alliance for Research and Technology (SMART), MIT’s research enterprise in Singapore, have developed a method to produce customizable engineered lysins that can be used to selectively kill bacteria of interest while leaving others unharmed. The discovery presents a promising alternative to antibiotics for treating existing drug-resistant bacteria and bacterial infections without the risk of causing resistance. Lysins are enzymes produced by bacteriophages to break open the bacteria……

One more clue to brain changes in...

Huntington’s disease is a fatal inherited disorder that strikes most often in middle age with mood disturbances, uncontrollable limb movements, and cognitive decline. Years before symptom onset, brain imaging shows degeneration of the striatum, a brain region important for the rapid selection of behavioral actions. As the striatal neurons degenerate, their “identity” proteins, the building blocks that give particular cell types their unique function, are gradually turned off. A new study from the lab of Institute Professor Ann Graybiel……

Automating material-matching for movies and video games

Very few of us who play video games or watch computer-generated image-filled movies ever take the time to sit back and appreciate all the handiwork that make their graphics so thrilling and immersive.  One key aspect of this is texture. The glossy pictures we see on our screens often appear seamlessly rendered, but they require huge amounts of work behind the scenes. When effects studios create scenes in computer-assisted design programs, they first 3D model all the objects that……

How Did Madagascar Become the World's Biggest...

It’s pretty likely that there is exactly one product from Madagascar in your home right now—no more, no less. That product is vanilla, and Madagascar is at the moment the world’s leading producer of this ubiquitous natural flavor—despite the fact that Madagascar is a very strange country to be the world’s leading producer of vanilla. Vanilla, at least the vanilla we eat, is not native to Madagascar; it originated some 10,000 miles away. Madagascar is also a chaotic place……

Ečka Kula in Ečka, Serbia

The village of Ečka is best known for its Kaštel (Castle), which is now a hotel, and its Art Colony. But just a short walk away from the Kaštel—one of the best preserved and most popular castles in Serbia, famous for the composer Franz Liszt playing piano there as a nine-year-old boy—are the ruins of an old water tower that looks like a part of a film set.  The inside is graffitied, plants are colonizing the roof, and the walls are deteriorating. The……

The Dutchman's Leap in Lerwick, Scotland

To this day, fishing and seafood represent a very significant part of Shetland’s economy. The main fish caught from the North Sea and Atlantic Ocean waters surrounding the archipelago include herring, cod, and mackerel. The first of these has been historically very popular in the Netherlands.  Between the early 17th and late 19th-centuries, Dutch fishing fleets chasing after the bountiful herring and other valuable shoals off the coast of Shetland would often dock in Lerwick during the summer. Large……

Trentino Alto Adige, now an Italian region, was contested between Italy and the Austro-Hungarian Empire during World War I, with much of the fighting concentrated in Southern Trentino. The area was located around the former border between the two powers. Here, thousands of people lost their lives in combat. Now, the remains of around 20,000 soldiers from both sides of the conflict are contained in the Sacrario Militare di Castel Dante (Castel Dante War Memorial). The war memorial is……

Nea Moni in Chios, Greece

According to legend, three monks miraculously found an icon of the Virgin Mary hanging from a myrtle branch on the island of Chios. The Nea Moni, or New Monastery, now stands on the site of this discovery, and it contains both centuries-old artwork and an ossuary filled with bones from the area’s greatest tragedy. Per the institution’s founding story, those three monks visited Constantine IX, then exiled on the nearby island of Lesbos. Told the story of the icon and a vision……
