New Research Re-Creates Planets in the Lab

New laser-based compression experiments by Lawrence Livermore National Laboratory (LLNL), Bayreuth University, and the University of California, Berkeley, have recreated conditions of cores of super-Earths, planets with masses five times that of the Earth. Through a combination of laser-driven shock compression, a technique that uses lasers to send a strong […]

Sharks Sink in Fresh Water

Sharks rank among the most feared predators in the world, but they have a surprising weakness – most cannot tolerate fresh water. Approximately forty percent of bony fish, such as goldfish and trout, live in fresh water. Sharks, on the other hand, belong to a group of cartilaginous fish called […]

Nanoparticle Drug Stops Cancer Proliferation in Mice

Dutch researchers have synthesized an anti-metastatic drug that may be delivered in selective, tumor-targeting nanoparticles (1). Most of the time, cancer-related deaths stem from a process known as metastasis, in which mutated cells at a certain origin spread through the vasculature to  other organs.  These cells avoid the immune system, […]

Noise and Competition in Gene Expression

On January 26, Rob Brewster, a postdoctoral scholar from the California Institute of Technology, gave a seminar on his research on modeling gene expression from a biophysics perspective. His research focuses on using physical laws to create models that can predict gene expression. Any model inherently overlooks certain factors, which […]

Squids can recode their genetic makeup according to their surroundings

Adaptation, the gradual modification of a specie’s features, is a fundamental part of evolution. There is plenty of evidence to support this slow, ongoing process that modifies the genetic makeup of species. A new study published by Dr. Eli Eisenberg of Tel Aviv University, in collaboration with Dr. Joshua Rosenthal […]

Wasp Virus Turns Ladybugs into Zombie Babysitters

A study conducted in France is beginning to shed light on the mechanisms by which green-eyed wasps can interfere with the neural circuit of the ladybugs they impregnate, ensuring that the ladybugs protect the cocoons of growing wasps (1). The relationship between ladybugs, or “lady beetles” to entomologists, and the […]

New drug-delivery capsule may replace injections

Time has shown that the use of nanotechnology in the medical field is on an exponential rise. One result of this progress is an innovative and effective drug-delivery system. Researchers at MIT and Massachusetts General Hospital have devised a capsule that uses micro-needles to inject a payload of drugs into […]

Odame: Wearable Biomedical Devices to Improve Treatment of Chronic Disease

In a seminar held January 9, Kofi Odame of the Thayer School of Engineering discussed his research on wearable biomedical devices and how these devices could move the healthcare industry towards adopting a more preventative, proactive model towards treating chronic diseases. Chronic diseases account for seven out of ten deaths […]
