Ebola Free-for-All Could Trigger Bad Science and Wasted Efforts

Everybody and his uncle, it seems, has an idea of something that might work to cure people infected with the deadly virus.

When it comes to treatments for Ebola, there has been a nearly four-decade-long drought. Nothing in the medical arsenal attacks the virus directly. For the most part, p... Read More

New molecules to burst malaria's bubble

Scientists have released details of a raft of new chemicals with potent anti-malarial properties which could open the way to new drugs to fight the disease.

A new paper in PNAS is the third published recently by a group at the Australian National University (ANU). The group has collaborated w... Read More

Mapping Human Disease: ‘Not All Pathogens Are Everywhere’

Researchers at North Carolina State University have for the first time mapped human disease-causing pathogens, dividing the world into a number of regions where similar diseases occur.

The findings show that the world can be separated into seven regions for vectored human diseases – diseases ... Read More

Gut bacteria from a worm can degrade plastic

Plastic is well-known for sticking around in the environment for years without breaking down, contributing significantly to litter and landfills. But scientists have now discovered that bacteria from the guts of a worm known to munch on food packaging can degrade polyethylene, the most common pl... Read More

Tool to edit DNA revolutionizing research in Boston area

It is a fascinating quirk of nature: Simple bacteria have an immune system with a memory, which allows them to destroy invading viruses they have encountered in the past.

The phenomenon is more than just a scientific curiosity. In just two years, scientists have discovered how to repurpose th... Read More

Ebola In The Air: What Science Says About How The Virus Spreads

Here's an Ebola puzzle for you: If the virus isn't airborne, why do doctors and nurses need to wear full protective suits, with face masks, while treating patients?

After we dug through studies and talked to scientists, the answer slowly emerged.

Ebola does spread through the air. But not ... Read More

Revealed: how bacteria drill into our cells and kill them

A team of scientists has revealed how certain harmful bacteria drill into our cells to kill them. Their study shows how bacterial ‘nanodrills’ assemble themselves on the outer surfaces of our cells, and includes the first movie of how they then punch holes in the cells’ outer membranes. The rese... Read More

Wireless Electronic Implants Stop Staph, Then Harmlessly Dissolve

Researchers at Tufts University, in collaboration with a team at the University of Illinois at Champaign-Urbana, have demonstrated a resorbable electronic implant that eliminated bacterial infection in mice by delivering heat to infected tissue when triggered by a remote wireless signal. The si... Read More

Sophisticated HIV Diagnostics Adapted for Remote Areas

Diagnosing HIV and other infectious diseases presents unique challenges in remote locations that lack electric power, refrigeration, and appropriately trained health care staff. To address these issues, researchers funded by the National Institutes of Health (NIH) have developed a low-cost, elec... Read More

Pirate viruses caught in their own trap?

In order to infect a host cell and proliferate, some viruses, such as the hepatitis C virus, infiltrate the ribosomes, the molecular machines that assemble the proteins present in each of our cells. Viral proteins are thus produced to the detriment of cellular proteins. A group of scientists in ... Read More

World AIDS Day: The History of a Virus in 7 Stories

Dec. 1 has been World AIDS Day since 1988 — but though the awareness and activism around the diseases has changed drastically during the years between then and now.

To see just how much our understanding and attitudes have evolved, take a look back at TIME’s coverage of AIDS through these sev... Read More

New antimicrobial edible films increase lifespan of cheese

New coatings to apply to soft cheese have been developed by researchers. These coatings are totally edible and have an antimicrobial capacity, which increases the lifespan of the cheese. These films incorporate oregano and rosemary essential oils as antimicrobial agents, and chitosan, a by-produ... Read More

Seeking answers from a mysterious parasite

Newly tenured biologist Jeroen Saeij wants to know what makes Toxoplasma gondii so unpredictable.

Toxoplasma gondii is a common parasite often spread by cats. Most people who are infected in Europe or North America show no symptoms at all, and only a few suffer from encephalitis or ocular tox... Read More

Genomes of malaria-carrying mosquitoes sequenced

Nora Besansky, O’Hara Professor of Biological Sciences at the University of Notre Dame and a member of the University’s Eck Institute for Global Health, has led an international team of scientists in sequencing the genomes of 16 Anopheles mosquito species from around the world.

Anopheles mosq... Read More

Is the Blood of Ebola Survivors an Effective Treatment?

When the World Health Organization recently named blood transfusions from Ebola survivors as its priority experimental therapy for the disease ravaging west Africa there was only one major problem: no data indicating that such transfusions work. Blood plasma from survivors contains antibodies th... Read More

Terminal Proteins: Endless Possibilities

Although it is far from unanimous, the great majority of phages studied so far package their genomes for intercellular space travel as linear chromosomes. Why linear rather than circular? Packaging convenience, for one thing. Many phages, including all of the tailed phages, package their chromos... Read More
