6 Amazing Things Before Breakfast #2

Welcome to the second post in my weekly blog series where you’ll learn 6 amazing things before breakfast. This post is a week late and I am sorry but, I was lucky enough to spend a week in Oxford for a chemistry conference and wasn’t able to post last week. You can check out my twitter @ALifeinBioMed for pictures of my trip!

So, let's learn #6AmazingThingsBeforeBreakfast …

  1. Super Slug Glue

Scientists have created a new type of glue which could be used to close up wounds in surgery, which was inspired by slug slime! The gel is made up of two layers - one that sticks to wet surfaces and one that absorbs stress (like a shock absorber), just like the slime of a type of slug called Arion subfuscus. “We are also engineering it further to make our material biodegradable, so it dissolves in the body once it has served its purpose,” says Jianyu Li at Harvard University. The material has already been tested on liver and beating hearts and is significantly better than a commercially available surgical glue, CoSeal.

  1. A Faster Way to Test your Alcohol
This story has applications in something I have a lot of experience in – alcohol.  We all know that different spirits have different tastes and this is because of the different compounds in each drink, called volatiles. Researchers from the University of Illinois at Urbana-Champaign have developed a fast, sensitive and cheap way to detect very tiny amounts of volatiles using a hand-held device. This very easy method can detect concentrations of volatiles that were previously hard to identify and has many applications including testing the quality control of spirits as well as the detection of chemical toxins in food and drink. It follows on from the work done with “electronic noses” which are less sensitive than this new method.

3)  Rush Hour Health Concerns

We all know that in rush hour, pollution increases in the air. A new study by researchers from Duke University, Emory University and the Georgia Institute of Technology have looked at the first in-car pollution measurements. Usually, any traffic pollution sensors are placed on the ground, alongside a road however, they can’t tell us how much pollution a driver is exposed too on a daily commute. “We found that people are likely getting a double whammy of exposure in terms of health during rush-hour commutes” says Professor Michael Bergin at Duke University…

4) Very Bad News for Antarctica

You might have seen this in the news but unfortunately, last week a absolutely gigantic iceberg broke off from Antarctica. It is now the largest iceberg ever recorded and, although scientists knew it was coming, this is not a good sign at all. You can watch a video of the crack in the ice appearing on LiveScience here.

5) Answering the Big Questions. Who would win in a fight between Magneto and Elastigirl?

I am so excited about The Incredibles 2 being released next year! And this next story just adds to the excitement! Physicist, Christian Binek at The University of Nebraska-Lincoln has made a breakthrough which would answer the age-old question “Who would win in a fight between Magneto and Elastigirl?” The answer – Magneto.

Binek has found that in some conditions, the magnetic properties of a material can predict its elasticity-temperature relationship. This means that, in the future, we could control how elastic a material is by subjecting them to a magnetic field or designing them with special magnetic properties.

6) Getting those Z’s in, in Space

This week The Royal Society have been asking people to nominate their favourite popular science book. The book that has inspired me the most is “Packing for Mars” by Mary Roach (you can find the book review I did here).

In the book, Mary explores the science that is happening right now to try and get humans to Mars and this next story follows on from the book perfectly. NASA’s Human Exploration Research Analog (HERA) has just completed a 45-day mission where sleep deprivation was tested. The crew were allowed to sleep for 5 hours a night, for 5 days a week and then had 2 normal, recovery days where they could get a normal amount of sleep. They were also NOT allowed to nap! This situation helped scientists learn about fatigue, how to combat it and how to predict it.

On a lighter note, the crew were asked what they did to relax in the 45-day mission confinement. To which they said, they liked to play board games and watch movies together (so cute).

I hope you’ve found these stories as interesting as I have. You can read more about them by clicking on the links.

See you next week!

6 Amazing Things Before Breakfast #1

This is the first post of my new weekly series where you will find 6 amazing new stories from the previous week - and hopefully read about them before breakfast. So grab that coffee and get comfy.

I gather so many news stories throughout the week that I think are interesting and need to be shared, however, most of them never get turned into full blog posts because frankly I just don’t have enough time at the moment.

So, inspired by #6AmazingThingsBeforeBreakfast, here are my top science news stories for the week…

  1. It’s SpongeBob SquarePants as you’ve never seen him - in the rainforests of Borneo

Read @GrrlScientist’s new article about the discovery of a new fungus called  Spongiforma squarepantsii. Found in the rainforests of Borneo by Professor Dennis Desjardin, Assistant Professor Kabir Peay and Professor Thomas Bruns, the formal description of the fungus was originally rejected by editors. Apparently, squarepantsii, which is the Latin for SpongeBob’s SquarePants was “too frivolous” but the team argued their case and the paper was published in the journal Mycologia this week (10th July 2017).

2)  Anti-aging research got skin-deep this week...

The outer part of the skin, the epidermis, is our bodies barrier to the outside world. In mouse models, older mice have a thicker epidermis than younger mice. A new paper by Wantanabe et al., published in eLife this week (11th July 2017) found that in the the distribution of COL17, a key collagen protein, changes dramatically in aged mice and human epidermis suggesting that this could be a promising new target for future anti-aging strategies.

3) A little early in the year BUT defrosting your car just got a whole lot easier!

Ever found yourself late for a meeting because your car took so long to defrost? Well, Professor Jonathan Boreyko at Virginia Technology College was fed up with waiting for his car to defrost so developed a “simple chemical recipe” which defrosts surfaces 10 times faster than normal! Metal plates were treated with the special recipe which made them super water repelling, so frost literally slides off when heat is applied. Check out these videos including an interview with Professor Boreyko…

4) Lord of the Flies, Cancer Edition

It is common for cancer cells to surround, kill and then eat another cell, called cell cannibalism, although it is not a well-studied part of cancer biology. However, new research has found a mechanism that drives this process - it is triggered when a cell divides.

One of the markers of cancer is uncontrolled cell division and this research has shown that cells which divide more (like cancer cells) are more likely to be eaten by healthy normal cells in the process of cell cannibalism. The relationship is very complicated and scientists aren’t sure whether cell cannibalism helps or hinders tumour growth, but this is a very exciting new avenue of research in the fight against cancer.

5) Measuring how “good” your good cholesterol is

Most people understand that we have good cholesterol and bad cholesterol in our bodies. High levels of bad cholesterol block blood vessels and is a main contributor to heart disease, with good cholesterol (called HDL) being the stuff which takes excess cholesterol away to the liver to be destroyed, lowering the chance for arteries to be blocked and hence, lowering the risk of heart disease.

Most doctors measure the amount of cholesterol collected by HDL however, a new test has been developed which instead measures how good HDL is at picking up excess cholesterol - basically, the test looks at how good HDL is at doing its job, rather than the end result of how much it's collected.

This simpler and faster way to measure how well HDL is doing its job is a better way to monitor and potentially prevent heart disease.

6) Reducing square-eyes from looking at your phone at night!

All our digital screens emit a high-energy blue light which can reach deep into the eye and cause damage if someone is exposed to it for a long time - which is increasingly the case nowadays.

In a first-of-its-kind study, scientists looked at if certain nutritional supplements which deposit in the eye could improve visual performance and protection for the eye when someone has a high screen-use lifestyle. The results showed that the supplement Lutemax 2020 significantly improved the symptoms associated with prolonged screen-time.

Apart from showing a nutritional-based therapy for prolonged screen exposure, the study also highlights the need for more research to be done on older and younger people, as the study was carried out on college-age students and showed a uniformed response.

I hope you’ve found these stories as interesting as I have. You can read more about them by clicking on the links.

See you next week!

Moth Eyes and Antireflective Phones

Summer is here! So that also means squinting really hard to try and read things on your phone screen outside – an annoyance I know all too well.
However, scientists at the College of Optics and Photonics (CREOL), University of Central Florida have developed a new antireflection film that could stop this problem happening. Currently, an iPhone has a surface reflection of 4.4% but this new material has only 0.23% surface reflection meaning that a lot less light will reflect off the surface making it easier to read in bright sunshine.

Seafood Poisoning, Shrimp Economies and Bacteria

Food poisoning caused by eating raw or undercooked seafood is very common. The Centers for Disease Control and Prevention (CDC) estimates that there are around 80,000 cases of seafood poisoning in the U.S. every year. What actually causes this is a bacteria called Vibrio parahaemolyticus - which sounds a bit like a Roman Gladiators name in my opinion.

Biofilms - An Update

You may remember some of my early posts about microbial biofilms (The Science Behind Cocowhite (and Product Review) and Bacteria – The Next Frontier). A biofilm is a sticky coating, made by a group of bacteria, which protects them from being killed by your immune system or by antibiotics. They are one of the biggest threats to patients when they are in hospital because they can form quickly on medical devices like artificial hips or knees and are very hard to remove – or so we thought...

The State of HIV Care in Europe

There are currently 36.7 million people living with HIV and is an important priority for all countries to address. The continuum of HIV care is a framework which helps countries to monitor how effectively they are dealing with the HIV epidemic and is part of the Dublin Declaration on Partnership to Fight HIV/AIDS in Europe and Central Asia (signed in 2004).

The continuum of HIV care has four key stages (see below). Each stage follows on from the previous one to help indicate to countries where resources and activities need to be focused on, or improved, to achieve the UNAIDS 90-90-90 targets.

The Future of Transportation

A new study, launched by MIT, will explore the future of transportation and what might affect it.

As part of the MIT Energy Initiative (http://energy.mit.edu/), a new study called "Mobility of the Future" has been launched to model the consequences of how technology, infrastructure, policy and consumer choices will affect the future of transportation. The study will mostly focus on ground transport and will have an emphasis on the movement of people.
