Best online sources for science news

There’s never been a better time to get up to speed on news of the latest science developments as science reporting has become increasingly mainstream, mainly because of all the exciting science that’s happening these days. Here are some great resources:

Conventional news sources

Many of the places you’d expect to find news have special science desks – good ones are the BBC News Science & Environment page, New Yorker’s Science & Tech section and Huffington Post Science.

Science-specific sites

There are many of these, providing constantly updated coverage of all the news in science. Get started with sites like Science Daily, which focuses on research news, New Scientist, geared more to the general population, and of course Popular Science.

Podcasts

Science podcasts offer a really great source of news in a whole range of fascinating subjects from astrophysics to neuroscience, often with a huge dose of humour in the mix. Try Star Talk Radio, You Are Not So Smart, and This Week in Science.

With websites like these to explore, as well as the host of fantastic science social media accounts you’ll find on Twitter, Facebook and Google+, you can stay abreast with all the marvellous new wonders of the universe being discovered in our fascinating age.

The Modern Scientific Method

The modern scientific method is the building block on which so much of modern world has been constructed. All the massive advances in computer science and communication technology that we have witnessed in the last few decades can be directly attributed to the use of the scientific method.

Some would argue that the formulation of the modern scientific method is one of humanity’s greatest ever inventions; with it providing the key that unlocked so many more doors of progress, in a huge variety of fields, from biology and medicine, to quantum physics and space travel.

As to who invented the modern scientific method, ancient Greek philosopher Aristotle certainly has a strong claim. While he and other Greek proto-scientists certainly contributed to the development of the method, particularly in their use of observation and measurement, their initial forays into science tend to lack the structure and precision of modern science.

It would be a fairer assessment to say that much modern scientific method was first formulated by scholars in the medieval Muslim world. Between the 10th and the 14th centuries CE, scholars in the Islamic countries of the world first began to identify and use the fundamentals of modern scientific method.

These fundamentals centre on seven basic principles, which shape the work of scientists today. These are:

  1. Making an observation of a phenomenon of the natural world.
  2. Making a clear statement of a definite problem.
  3. Formulating a sound hypothesis.
  4. Testing the ideas behind the hypothesis through properly designed experiments.
  5. Recording, assessing and analysing the results of those experiments.
  6. Interpreting and presenting the data of those experiments in a coherent and scientifically sound way.
  7. Finally, publishing the findings of this process of observation, experimentation and analysis.

These look like an uncomplicated set of steps, but their simple nature is deceptive. These seven stages have formed the basis for the bast majority of successful experiments, which in turn has led to huge breakthroughs in every area of human life.

Whether you enjoy drinking soda pop, use an asthma inhaler, or drive a car, all the technology that you are enjoying can be traced to someone, somewhere, using the scientific method.

The Biggest Modern Breakthroughs in Medical Research

The history of medicine reaches as far back as the ancient period, yet just a few major discoveries stand out in the public’s mind. From the first heart transplant through to the discovery of antibiotics, medicine has had a lot to offer over the years. While older discoveries are certainly tantalising, there are modern versions that have a lot to offer too.

The HPV Vaccine

As one of the most aggressive female cancers, cervical cancer kills millions of women each year. While vaccine therapies have been explored for decades in relation to cancer, finding one that works has proven to be a challenge for scientists. Today, girls and women aged between 13 and 26 can access a preventative vaccine that significantly reduces their risk of HPV. Not only will this benefit women in the developed world, access in the developing world can significantly enhance women’s health there.

Fecal Transplants

On the face of things, fecal transplants may sound a little gross. However, when it comes to tackling some of the world’s most stubborn bacteria, they can save lives. Clostridium difficile is a violent pathogen that primarily causes infections in a healthcare setting. Thanks to its biological makeup, it’s incredibly hard to tackle. Today, patients can receive fecal transplants that have a 90 percent cure rate, allowing them to get back to good health.

The Use of Maggots to Battle MRSA

If you’ve ever worked in healthcare, you’ll already know how MRSA strikes fear in the hearts of clinicians and patients alike. While antibiotics have acted as life savers during the 20th century, overuse has led to resistance amongst certain bacteria. Researchers at Swansea University in the UK have taken medicine back to basics by using maggots as a form of wound therapy. When maggots are applied to wounds, they secrete a substance patented as ‘Seraticin’, which is antibacterial, antifungal, and too overpowering for MRSA to resist. Fortunately for squeamish patients, researchers are now working towards bottling Seraticin so it can be used without maggots being present.

Long Lasting Contraceptive Microchips

Until 2014, the longest acting contraceptive was the copper IUD, which can give women an impressive chance of staying pregnancy free for 10 years. After more than a decade of scientific development, it looks as though the contraceptive microchip is ready to take the copper IUD’s crown. Not only does it release 30mg of levonorgestrel on a daily basis, it’s possible to turn it on and off at will. As women return to their fertile potential almost immediately after stopping the hormones, it offers contraceptive flexibility that might remain unparalleled for some time now.

HIV Cocktails

After gripping the world with fear in the 1980s and 1990s, HIV is now a condition that can be relatively well controlled. In the last year, scientists have pin pointed combinations of antiretroviral drugs that help patients fight off side-effects, reach their life expectancy, and reduce the risk of spread. Compared to the decade HIV first became evident, which saw slow and painful deaths, this is astounding progress.

With science moving at a rapid pace, the world is sure to see further breakthroughs throughout the 21st century.
