Newly Designed Nanoparticles Can Deliver Three Cancer Drugs at a Time

April 15, 2014

2 Comments

In a newly published study, MIT chemists detail how they designed nanoparticles that can deliver three cancer drugs at a time. Delivering chemotherapy drugs in nanoparticle form could help reduce side effects by targeting the drugs directly to the tumors. In recent years, scientists have developed nanoparticles that deliver one or two chemotherapy drugs, but […]

New Technique Allows Particles to Switch the Quantum State of Each Other

April 10, 2014

0 Comments

Researchers from MIT and Harvard University have developed a new technique that couples a lone atom with single light particle, allowing both the atom and photon to switch the quantum state of the other particle. Using a laser to place individual rubidium atoms near the surface of a lattice of light, scientists at MIT and […]

Study Shows Nanoparticles in Consumer Products Can Damage DNA

April 9, 2014

2 Comments

Using high-speed screening technology to analyze DNA, a newly published study found that nanoparticles commonly added to consumer products can significantly damage DNA. Thousands of consumer products — including cosmetics, sunscreens, and clothing — contain nanoparticles added by manufacturers to improve texture, kill microbes, or enhance shelf life, among other purposes. However, several studies have […]

Fermi Data Reveal New Clues to Dark Matter

April 4, 2014

1 Comment

New maps from the Fermi-LAT Collaboration show that the galactic center produces more high-energy gamma rays than can be explained by known sources, suggesting that this excess emission is consistent with some forms of dark matter. A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that […]

MIT Researchers Reverse a Rare Liver Disorder in Mice

April 3, 2014

1 Comment

In a newly published study, MIT researchers show that a new gene-editing technique, known as CRISPR, can reverse a rare liver disorder caused by a single genetic mutation. Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation. The findings, […]

New System Filters Light Waves Based on Direction

March 28, 2014

0 Comments

Researchers from MIT have produced a system that allows light of any color to pass through only if it is coming from one specific angle. Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to its color […]

Researchers Propose Using Distant Quasars to Test Bell’s Theorem

February 20, 2014

0 Comments

A team of researchers has proposed a practical scheme to use photons from causally disconnected cosmic sources to set the detectors in an experimental test of Bell’s inequality. In a new paper, MIT researchers propose an experiment that may close the last major loophole of Bell’s inequality — a 50-year-old theorem that, if violated by […]

Graphene Effectively Filters Electrons According to the Direction of Their Spin

December 26, 2013

0 Comments

New research from MIT shows that graphene can effectively filter electrons according to the direction of their spin, something that cannot be done by any conventional electronic system. Graphene has become an all-purpose wonder material, spurring armies of researchers to explore new possibilities for this two-dimensional lattice of pure carbon. But new research at MIT […]

A New Technique for Determining the Mass of Exoplanets

December 20, 2013

0 Comments

MIT researchers have developed a new technique for determining the mass of exoplanets using only their transit signal, helping researchers determine the mass of exoplanets that are not measurable in any other way. To date, scientists have confirmed the existence of more than 900 exoplanets circulating outside our solar system. To determine if any of […]

Study Shows Creation of Entanglement Simultaneously Gives Rise to a Wormhole

December 11, 2013

2 Comments

In a newly published study, an MIT physicist details how the creation of two entangled quarks simultaneously gives rise to a wormhole connecting the pair. The theoretical results support the idea that the laws of gravity holding together the universe may not be fundamental, but arise from quantum entanglement. Quantum entanglement is one of the […]

Researchers Reveal How an Expanding Universe Can Emerge Without a “Big Bang”

December 10, 2013

2 Comments

In a new study, an international team of researchers mathematically describe how an expanding universe can emerge when time and space are heated, without requiring anything like a “Big Bang”. When soup is heated, it starts to boil. When time and space are heated, an expanding universe can emerge, without requiring anything like a “Big […]

Mars “Shakes Up” Asteroid Surfaces

November 20, 2013

0 Comments

A new study from MIT researchers has found that Mars, like Earth, can “refresh” asteroid surfaces if in close enough contact. For nearly as long as astronomers have been able to observe asteroids, a question has gone unanswered: Why do the surfaces of most asteroids appear redder than meteorites — the remnants of asteroids that […]
