The world’s first malaria vaccine was given a positive opinion by the European Medicines Agency--Europe’s drug regulator, comparable to the FDA--according to an announcement made today by GlaxoSmithKline, the vaccine’s maker. The positive review does not mean that the vaccine is approved for use. Rather, the WHO will now take this opinion into consideration when they come up with their own recommendation. If the vaccine gains approval from the WHO, then GlaxoSmithKline will market the drug to individual African countries.

Magnetic Nanoparticles Found to Boost Immunotherapy

15 July 2015. Researchers at Johns Hopkins University designed a process for making immunotherapy more practical as a cancer treatment by collecting cancer-fighting T-cells faster and easier with magnetic synthetic antigen nanoparticles. The team from the lab of Jonathan Schneck, professor of pathology at Johns Hopkins University medical center in Baltimore, published results of lab tests of that process in yesterday’s issue of the journal ACS Nano (paid subscription required).

A new drug has been found that fast-tracks tissue regeneration - ScienceAlert

In news that sounds like it’s come straight out of science fiction, researchers in the US have discovered a drug that rapidly repairs damage to the colon, liver and bone marrow in mice, without any adverse side effects. It even saved the lives of mice that would have otherwise died as a result of a bone transplant.

The drug hasn’t been tested on people just yet, but the team are now working on developing it for human use within the next three years, with the hope that it could drastically reduce recovery times and improve survival outcomes after surgery and injury.

Scientists observe altruism and selfishness in brain activity

Prosocial behavior is fundamental to the sustainability of society, enabling people to work in groups, to create larger and more successful social structures, and to contribute to the common welfare. However, despite the importance of altruism, science has only a limited understanding of how prosocial behaviors and selfish behaviors are represented in the brain. Additionally, individual transition between self-benefiting behavior and altruistic behavior is not well understood.

Scientists discover an enzyme that can change a person’s blood type - ScienceAlert

Scientists have discovered that a particular type of enzyme can cut away antigens in blood types A and B, to make them more like Type O - considered the 'universal' blood type, because it’s the only type that can be donated to anyone without the risk of provoking a life-threatening immune response.

Diabetes drug found in freshwater is a potential cause of intersex fish

A medication commonly taken for Type II diabetes, which is being found in freshwater systems worldwide, has been shown to cause intersex in fish -male fish that produce eggs.

Scientists told to stop wasting animal lives | Science | The Guardian

Research agencies have ordered UK scientists to improve the way they use animals in experiments. Too often poorly designed projects – to test new medicines for strokes, cancer and other conditions – have produced meaningless results and wasted animals’ lives, the organisations have warned.

In some cases, researchers – desperate to control the costs of their work – have underestimated the number of animals needed to test a new medicine. As a result, their tiny studies have lacked the power to pinpoint biological effects in the drugs under scrutiny. These unreliable...

Pancreatic cancer breakthrough: scientists turn cancer cells into normal cells

A new research study has shown that pancreatic cancer cells can be coaxed to revert back toward normal cells by introducing a protein called E47. E47 binds to specific DNA sequences and controls genes involved in growth and differentiation. The research provides hope for a new treatment approach for the more than 40,000 people who die from the disease each year in the United States.

Resistance to antibiotics found in isolated Amazonian tribe | Science/AAAS | News

When scientists first made contact with an isolated village of Yanomami hunter-gatherers in the remote mountains of the Amazon jungle of Venezuela in 2009, they marveled at the chance to study the health of people who had never been exposed to Western medicine or diets. But much to their surprise, these Yanomami’s gut bacteria have already evolved a diverse array of antibiotic-resistance genes, according to a new study, even though these mountain people had never ingested antibiotics or animals raised with drugs. The find suggests that microbes have long evolved the capability to fight...
