Chemicals in insecticides could affect our sense of day and night.

Insecticides may alter our circadian rhythm

University at Buffalo biologists recently discovered that toxic chemicals commonly found in insecticides have the ability to change the way our biological clocks function. The researchers believe that they have uncovered the previously unknown mechanism by which insecticides put people at higher risk for metabolic diseases like diabetes.

A serious bacterial infection rendered Benoit unable to receive a lung transplant.

Woman survives six days without lungs

It has been proven that humans can survive without appendices, gallbladder, spleen and even parts of their pancreas and liver, but the lung has always been considered an essential organ. That is, until thoracic surgeons at Toronto General Hospital of University Health Network, successfully resected the infected lungs of a dying woman.

Physical and mental birth defects may be antidepressant-associated.

Antidepressants increase risk of birth defects

Depression is becoming a more prevalent, and it has the tendency to occur especially more frequently during pregnancy. Depression during pregnancy is essentially a biological illness that acts similarly to any other kind of clinical depression by altering brain chemistry.

Research found that sugar type plays a role in determining health risk.

Sugar consumption increases health risks

Sugar comes in many different forms, including fructose, which is often found in fruit and fruit juices, and glucose, one of the simplest forms of sugar into which carbohydrates are broken down in the body.

Titanium repels blood, limiting blood contact with surface to prevent clotting.

Titanium implants tackle blood clots head-on

While medical implants such as stents, catheters and various forms of inserted tubing provide medical benefits to many patients, these implanted devices pose great issues to a vast array of those with them. More specifically implanted devices increase risks of blood clots and infections in patients who need them.


New group of stars discovered in our Milky Way

An astronomer from the Liverpool John Moores University (LJMU) Astrophysics Research Institute has found a new group of stars within our Milky Way Galaxy. The implications of this discovery could be enormous, as this sheds light on the early stages of the formation of the Milky Way Galaxy.

Chromosomes (the dense, purple clumps) may contain less DNA than previously thought.

DNA might make up only half of chromosomes

In a recent study published in the journal Molecular Cell, scientists discovered that DNA may make up only about half of the material found in chromosomes. In fact, up to 47 percent of a chromosome’s makeup may consist of a sheath, or a protective structure, surrounding DNA.

Intrafasicular multielectrode stimulation can help stimulate fatigue-resistant muscles.

Multielectrode stimulation can treat paralysis

Imagine yourself sitting comfortably in a car, gazing through the window at the oak trees gradually coming into sight and then vanishing quickly in a blur as the wheels continue in its steady, rolling motion. A flash of light blinds your eyes momentarily, fear immediately disperses across your entire body. The airbag in front bursts out shortly, and a huge mass crashes into your door.

Currently, trucks use diesel fuel, which is harmful for the environment.

New truck can run on hydrogen fuel cells

The Nikola Motor Company is developing a Class 8 truck, the Nikola One, that comes equipped with hydrogen fuel cell technology. Class 8 trucks are more commonly known as 18-wheelers, or semi-trucks, and have traditionally used diesel fuel as a form of energy.

A newly developed USB stick device only needs one drop of blood to test for HIV.

HIV tests can be performed on a USB stick

Scientists at the Imperial College London and DNA Electronics, a U.K. biotech firm, have developed a new device that could change the way doctors and patients monitor HIV levels in the bloodstream.

Mental health disorders can lead to physical diseases in teenagers.

Mental disorders tied to specific physical diseases

Scientists have known for a while that mental disorders are often observed in conjunction with physical diseases. Previous studies have primarily focused on how the two are associated in adult populations. Researchers at the University of Basel and Ruhr-University Bochum studied young individuals and are beginning to link specific mental disorders to certain physical ailments in younger populations.
