Explainer: What is microgravity?

It's easy to assume that astronauts float in space because they are far away from the Earth's gravitational force. But look at the moon. It is much further away than the International Space Station, yet it orbits around the Earth because it is perpetually attracted by its gravitational pull. So if the Earth's gravity can affect the moon, the astronauts cannot be floating because there is no gravity where they are.

Chemistry news

A new Diels-Alder reaction

(Phys.org)—The Diels-Alder reaction is a mainstay in organic chemistry. The reaction traditionally involves a diene and a dienophile. The diene has four carbons that are sp2 hybridized to form pi bonds. The dienophile has two sp2 hybridized carbons. The diene and dienophile undergo a cycloaddition reaction to form a cyclohexene. This reaction can be tweaked to make six-membered rings with a higher oxidation state by removing hydrogens from the reactants to make sp hybridized carbons. For example, rather than an alkene and a diene reacting, the reactants could be an alkyne and an allenyne.

Creating a reduced-fat chocolate that melts in your mouth

Chocolate is divinely delicious, mouthwateringly smooth and unfortunately full of fat. But reducing the fat content of the confection makes it harder and less likely to melt in your mouth. That's why scientists are investigating additives that could reinstate chocolate's delightful properties in these lower-fat treats. Now, researchers report in ACS' Journal of Agricultural and Food Chemistry an analysis that sheds light on how adding limonene could improve lower-fat versions' texture and ability to melt.

A molecular switch to better understand signaling

In the alphabets of our genomes, a single typo can mean the difference between health and disease. The "words" are molecules, like enzymes, and one group of these called kinases are particularly important. However, it's difficult to pick apart the exact roles of misspellings in various kinases in a disease process. This week in ACS Central Science, researchers report development of a new way to determine this, both in a lab dish and in mice.

What's the right question to ask about GMOs?

I would argue that the source of a transgene and its method of introduction are irrelevant to the safety of the resulting plant. A gene is a gene — it is a sequence of DNA and, as a molecule, DNA has zero chance of harming you. The DNA can be from any organism — literally, any organism — and it is still just a sequence of the same chemical letters, A, T, G, and C. Moreover, the method of transgene introduction, be it by plant breeding or by transformation, has no effect on the action of the gene product in the cell. Either the gene is present and active, or it is not.

Study finds relationship between trade-related U.S. job losses and political polarization in Congress

In recent years economic studies have illuminated the extent to which global trade agreements, while benefitting many consumers, have also led to significant job losses in the U.S.—particularly due to jobs moving to China after 2001. Now a new study co-authored by MIT economist David Autor (along with non-MIT colleagues David Dorn, Gordon Hanson, and Kaveh Majlesi) identifies a political effect from this economic process. From 2002 through 2010, in U.S. congressional districts particularly affected by job losses due to trade, elected members of the House of Representatives becamemore ideologically extreme, with moderates consistently losing out in both parties. Autor spoke to MIT News this week about the headline-grabbing results.
