Polycyclic aromatic hydrocarbons have lingering carcinogenic effects.

Aromatic hydrocarbons increase cancer risk

Polycyclic aromatic hydrocarbons (PAHs) are naturally occurring chemicals released by the combustion of organic matter, including wood, coal, oil and gasoline. As a result of increased biofuel consumption in recent years, PAHs have become major pollutants in the atmosphere and 15 PAHs have been identified as carcinogens.

Pancreatic tumors are treatable by surgical removal only at early stages.

Studies show longer cancer survival rates

A recent clinical study conducted by the charity Pancreatic Cancer UK showed that a combination of two chemotherapy drugs helped to extend survival time  for pancreatic cancer patients. A separate research study showed an increase in survival rate for patients suffering from lung cancer. Pancreatic cancer has the worst survival rate among the commonest forms of cancer, while lung cancer has the second worst survival rate.

LSD is a psychedelic drug used to cause hallucinogenic effects and spark creativity.

Scientists unearth LSD binding mechanism

One of the most commonly known hallucinogens has actually gone misunderstood for quite some time now. Lysergic acid diethylamide, usually referred to as “LSD” or “acid”, is one of the most potent hallucinogens, and its effects can last for over 12 hours after the initial usage.

The UTL was awarded the Platinum certification for being an energy efficient building.

UTL lauded for its environmental efficiency

Trekking across campus to the Bloomberg Department of Physics or the Recreation Center, it is impossible to miss the iconic four-story-high Undergraduate Teaching Laboratories (UTL) building. Though you may have noticed its glazed-glass exterior and cells of students and staff alike conducting experiments, the UTL stands out this year for a different reason: its platinum certification from the Leadership in Energy and Environmental Design (LEED) program.

Trump’s visa ban could be a detriment to tech companies like Google.

Tech companies could be impacted by Trump’s ban

President Donald Trump’s executive order on immigration prevents non-U.S. citizens in seven Middle Eastern countries — Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen —  from setting foot in the United States.

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.
