Scientists at the University of Liverpool have discovered a new process to make polymers out of sulfur which could provide a way of making plastic that is less harmful to the environment.

Sulfur is an abundant chemical element and can be found as a mineral deposit across the world. It is also a waste product from the refining of crude oil and gas in the petrochemicals industry, which generates huge stockpiles of sulfur outside refineries.

Vitamin D has been found to speed up the clearance of tuberculosis (TB) bacteria from the lungs of people with multi-drug resistant TB, according to a study of 1,850 patients receiving antibiotic treatment, led by Queen Mary University of London.

Lead researcher Professor Adrian Martineau from Queen Mary University of London said: "Multi-drug resistant TB is on the rise globally. It's notoriously difficult to treat, and it carries a much worse prognosis than standard TB.

A smaller portion of fish and chips has been embraced by takeaway owners and customers, research has found and may well be healthier for us.

Experts led by Newcastle University worked with independent fish and chip supplier, Henry Colbeck to see whether people could be encouraged to eat a healthier size portion which led to the development of the Lite-BITE® box. Its smaller dimensions ensures a smaller portion of fish and chips coming close to 600 calories compared to an average fish and chip meal containing over 1,600 calories.

Medical marijuana has gained attention in recent years for its potential to relieve pain and short-term anxiety and depression. Now, Penn State College of Medicine researchers say some cannabinoid compounds may actually inhibit the growth of colon cancer cells in the lab.

The researchers tested the effects of synthetic cannabinoid compounds on colon cancer cells in an experiment in test tubes. While the compounds most commonly associated with cannabis -- THC and CBD -- showed little to no effect, 10 other compounds were effective at inhibiting cancer cell growth.

Remote recording devices used to 'eavesdrop' on a reintroduced population of one of New Zealand's rarest birds have been heralded as a breakthrough for conservation.

Scientists from international conservation charity ZSL (Zoological Society of London), Imperial College London and conservationists from the Rotokare Scenic Reserve Trust used acoustic monitoring devices to listen in on the 'conversations' of New Zealand's endemic hihi bird, allowing them to assess the success of the reintroduction without impacting the group.

Researchers have found that the brain stores detailed information of a missing hand decades after amputation, regardless of whether amputees still experience phantom hand sensations.

Their study, published in eLife, revealed detailed hand information in the brains of amputees compared with people who had been born with a missing hand. The research could pave the way for the development of next-generation neuroprosthetics - prosthetic limbs that tap into the brain's control centre.

Many countries have passed environmental laws to preserve natural ecosystems. Although the regulations seem to have improved preservation efforts, they may have had unintended consequences in energy production, leading to more greenhouse gas emissions.

That's the conclusion of a new study by a researcher at Carnegie Mellon University that appears in the journal PLOS ONE.

Mechanical systems, such as engines and motors, rely on two principal types of motions of stiff components: linear motion, which involves an object moving from one point to another in a straight line; and rotational motion, which involves an object rotating on an axis.

Today, thousands of databases with biological data are publicly available. They include data on gene and protein sequences and detailed measurements of different cellular parameters, such as the exact quantities of all proteins produced and degraded by a given cell in various experimental conditions. Brazilian researchers explored mRNA and protein public databases and found out how gene sequence choice can predict different aspects of protein synthesis, such as protein production efficiency.

The feedback from doctors seemed almost appalling.

One woman remembers her gynecologist stating, "Well, girl, you better, because if you don't, somebody else will."

Another said, "My doctor was really excited to tell [my partner] at six weeks that I was ready to go."

Yes, we're talking sex. After childbirth.
