Research Leads to New Understanding of How Cells Grow, Shrink

May 16, 2014 1:19 pm | Videos | Comments

For a century, biologists have thought they understood how the gooey growth that occurs inside cells causes their protective outer walls to expand. Now, researchers have captured the visual evidence to prove the prevailing wisdom wrong.

The Promise of Personalized Medicine: An Apples-to-Apples Approach

May 16, 2014 12:18 pm | Videos | Comments

In our sixth video, Andrew Wiecek wraps up the discussion by taking a look at one of the therapeutic areas that could be significantly improved by personalized medicine: cancer. The approach is similar to comparing apples to apples, he says.

Red Wine May Not Prevent Heart Disease, Prolong Life

May 16, 2014 10:39 am | News | Comments

There is bad news for those who believe drinking red wine is protecting their hearts and extending their lives. A study found that a plant compound in grapes—resveratrol—may not provide such health benefits. The nine-year study found resveratrol had no significant effect on longevity, inflammation, cardiovascular disease, or cancer.

Blood Seeking Mosquitoes

May 15, 2014 12:41 pm | by Skip Derra | Articles | Comments

Insights into controlling mosquitoes often focuses on how they are attracted to humans, which is by smelling the carbon dioxide we exhale. But once they get close to us, mosquitos often steer toward exposed areas of skin such as ankles and feet. New research has shown that an often overlooked mosquito organ, the maxillary palp, plays an important role in mosquito targeting.

Hazardous Flame Retardants Found in Child Care Settings

May 15, 2014 11:17 am | News | Comments

A new study of preschools and day care centers finds that flame retardants are prevalent indoors, potentially exposing young children to chemicals known to be hazardous.                       

Where Have All the Mitochondria Gone?

May 15, 2014 11:16 am | Videos | Comments

It’s common knowledge that all organisms inherit their mitochondria—the cell’s “power plants”—from their mothers. But what happens to all the father’s mitochondria? How—and why—paternal mitochondria are prevented from getting passed on to their offspring after fertilization is still shrouded in mystery.

Caffeine Helps Premature Babies Breathe Easier

May 15, 2014 11:12 am | News | Comments

The caffeine in coffee that might help get you going in the morning can be lifesaving for premature babies. For more than a decade, neonatologists have routinely given premature newborns caffeine as a respiratory stimulant, helping their immature lungs and brains remember to breathe.

Measles Vaccine Can Kill Multiple Myeloma Cells

May 15, 2014 11:00 am | Videos | Comments

In a proof-of-principle clinical trial, researchers have demonstrated that virotherapy— destroying cancer with a virus that infects and kills cancer cells but spares normal tissues— can be effective against the deadly cancer multiple myeloma.   

Single Episode of Binge Drinking Linked to Gut Leakage and Immune System Effects

May 15, 2014 10:52 am | News | Comments

A single alcohol binge can cause bacteria to leak from the gut and increase levels of bacterial toxins in the blood, according to a study funded by the National Institutes of Health. Increased levels of these bacterial toxins, called endotoxins, were shown to affect the immune system, with the body producing more immune cells involved in fever, inflammation, and tissue destruction.

Scientists Investigate the Role of the ‘Silent Killer’ Inside Deep-Diving Animals

May 15, 2014 10:36 am | News | Comments

Carbon monoxide is produced naturally in small quantities in humans and animals, and in recent years medical researchers have evaluated the gas as a treatment for diabetes, heart attacks, sepsis, and other illnesses. Scientists have furthered understanding of carbon monoxide’s natural characteristics and limitations by studying the gas in one of the world’s best divers: the elephant seal.

Anti-Depressant Reduces Alzheimer’s Plaque Growth by 78 Percent

May 14, 2014 2:03 pm | by Cynthia Fox | Articles | Comments

A common antidepressant can dramatically halt growth of Alzheimer’s plaque. A team from Missouri and Pennsylvania report today in Science Translational Medicine this reduction occurs in both humans and mice. It gives the drug, the selective serotonin reuptake inhibitor (SSRI) citalopram, a possible future role as a prophylactic—the first in Alzheimer’s Disease (AD), if bigger studies are supportive.

A New Approach to Treating Peanut and Other Food Allergies

May 14, 2014 1:35 pm | News | Comments

These days, more and more people seem to have food allergies, which can sometimes have life-threatening consequences. Scientists report the development of a new type of flour that someday could be used in food-based therapies to help people better tolerate their allergy triggers, including peanuts.

Microchip-Like Technology Allows Single-Cell Analysis

May 14, 2014 1:12 pm | Videos | Comments

A U.S. and Korean research team has developed a chip-like device that could be scaled up to sort and store hundreds of thousands of individual living cells in a matter of minutes. The system is similar to a random access memory chip, but it moves cells rather than electrons.

E-Cigarettes Expose People to More than ‘Harmless’ Water Vapor

Damaged Protein Could be Key to Premature Aging

May 13, 2014 2:25 pm | News | Comments

Scientists have found that the condition of key proteins in the mitochondria -the batteries of cells- could be used to predict, and eventually treat premature Aging. And restricting diet could be one way of making this happen. The researchers used interventions, like calorie restriction, a system whereby the cells are deprived of nutrients and which in previous studies has been shown to cause mice to live longer than normal.

Implanted Transistors Wrap Around Tissues

May 13, 2014 2:16 pm | Videos | Comments

Researchers from The University of Texas at Dallas and the University of Tokyo have created electronic devices that become soft when implanted inside the body and can deploy to grip 3-D objects, such as large tissues, nerves and blood vessels. These biologically adaptive, flexible transistors might one day help doctors learn more about what is happening inside the body, and stimulate the body for treatments.

Researchers Find New Molecule to Treat Asthma
