Don’t Be Impressed By Other People’s Skills Or Knowledge

by Katja Keuchenius in United Academics

Researchers Hays, Kornell and Bjork studied the effect of making mistakes on people’s learning in various experiments. They conclude that it can be a good thing to not yet know the answer. It makes you better remember the subject. So instead of guiding students step-by-step and avoid to let them get anything wrong, it is better to make it a bit too difficult for them.... Read more »

Getting Science Right: Investigating Casual Sex

by Katja Keuchenius in United Academics

Studies suggest that a majority of emerging adults, both men and women, will experience one or more casual sex encounters and that these encounters are associated with lowered psychological well-being, physical dangers and negative relationship outcomes. Is this trustworthy?... Read more »

The Inevitability of Sea Level Rise

by Anders Levermann in United Academics

Small numbers can imply big things. Global sea level rose by a little less than 0.2 metres during the 20th century – mainly in response to the 0.8 °C of warming humans have caused through greenhouse gas emissions. That might not look like something to worry about. But there is no doubt that for the next century, sea level will continue to rise substantially. The multi-billion-dollar question is: by how much?... Read more »

Sweet and Sour: Blood Sugar Linked to Dementia

by Rebekah Morrow in United Academics

As a junk food lover, I found this news really depressing. The New England Journal of Medicine recently published an article on a study conducted by researchers from the University of Washington. The study followed a large group of subjects (about 2,000) for an average of almost seven years to look at the effects of blood glucose levels on the chance of developing dementia.... Read more »

Novel Early Strategies to Reduce Increasing Allergic Conditions

by Guillaume Cote-Maurais in United Academics

The specific vulnerability of the immune system to recent environmental changes is reflected in the dramatic increase in virtually all inflammatory disorders, such as allergy and autoimmunity. Furthermore, clinical expression of allergy within the first months of life and detectable immune dysregulation at birth provide clear evidence of very early environmental effects. Already, approximately 30% to 40% of the world’s population is affected by one or more allergic conditio... Read more »

Scientists Plumb Blue Whales’ Secrets by Looking in Their Ears

by Josephine Lethbridge in United Academics

How do you get to know one of Earth’s most mysterious creatures? By looking at its earwax, according to a group of US researchers. Analysing the contents of blue whales’ ears, through a process similar to analysis of tree rings, led the team to construct a chemical timeline of the its life. This technique, they say, should allow significant further research both into how blue whales develop and how they respond to environmental concerns.... Read more »

Infants Give a Helping Hand, Even When You Look Like an Egg

by Dyani Lewis in United Academics

A baby’s first year of life is all take and very little give. “Change my nappy!” “Feed me!” “Me! Me! Me!”

We all start out as very demanding, seemingly thankless creatures. But collectively we make up one of the most social species on Earth. As we develop, we all acquire the abilities needed to participate in a give-and-take society.

Young children start helping their parents – and other adults – soon after their first birthday. If an adult drops something – say a clothes peg when trying to hang up the washing – the chubby fingers of an observant toddler could come to the adult’s aid.... Read more »

More than Genes? DNA Methylation in Great Apes

by Gunnar de Winter in United Academics

You’ve probably heard that human beings and chimpanzees share almost 99% of their DNA. But is this enough to explain the many differences we see between ourselves and our evolutionary cousins?*

Enter DNA methylation. When a methyl group (CH3) binds to DNA, this can alter the expression of the gene that that specific DNA sequence represents. So, two genes, identical in sequence, can be expressed differently depending on the methyl groups bound to it.

A new study, published in PLOS Genetics, has investigated the methylation patterns in the DNA of humans, chimpanzees, bonobos, gorillas and orangutans**. And indeed, the researchers found several differences in their comparative analysis.... Read more »

Natural Killer Cells Play Role in Recurrent Miscarriage

by Jo Adetunji in United Academics

Suffering a miscarriage can be a very distressing experience but for many women their next pregnancy is a normal one. For women, however, who suffer recurrent miscarriage, where they have three or more in a row, it can be utterly devastating.

More frustrating still is that in many cases – more than half – doctors are unable to find an underlying cause or offer more than just a handful of options for treatment... Read more »

Gay, bi, or hetero? Three ticking boxes for sexual orientation no longer sufficient.

by Katja Keuchenius in United Academics

Being attracted to one gender only is só last century. That’s at least the idea you get when reading Elizabeth Morgans just published review of various international studies on the sexual orientation of youth and emerging adults. It seems that many youngsters are not easily placed in a box of perfectly corresponding sexual orientation, identity, fantasy and experience. New generations are instead getting increasingly sexually flexible.... Read more »

One Day My Prince Will Bomb: Why Teenage Girls Love a Killer

by Linda Peach in United Academics

Prince Charming and the boy accused of the Boston bombings may not seem to have much in common. But thousands of teenage American girls appear to be falling in love with 19-year-old Dzhokhar Tsarnaev, and the explanation may lie in a very awkward place indeed – somewhere between the shining armour and the poisoned apple.

Tsarnaev has become the focal point for a number of fan clubs on social media, largely comprising teenage girls protesting his innocence and professing undying love. Two Facebook groups have 8,400 and 13,500 members respectively.... Read more »

Resurrecting Dinosaurs Will Remain a Jurassic Park Dream

by Michael Parker in United Academics

On the same day that the of the Jurassic Park film series has been confirmed, a study published in the journal PLOS One has detailed experiments that seem to prove once and for all that dinosaurs will never again walk the Earth.

The 1993 film, based on a book by Michael Crichton, depicts a theme park island filled with dinosaurs, resurrected from ancient DNA extracted from fossilised mosquitoes trapped in amber.

In the early 1990s, several scientists announced they had extracted DNA from insects fossilised amber as long as 130 million years ago. Insects from this time in Earth’s history, the early Cretaceous period, would have flown among dinosaurs such as flying pterosaurs, swimming plesiosaurs, giant, long-necked sauropods, among the largest creatures ever on land, feathered birds and mammals....

Youngsters Learn More From Good News than Dire Warnings

by Sunanda Creagh in United Academics

Many children and teenagers see themselves as immune to the risk of accidents and injury.

Now, new research suggests that pointing out the positive aspects of avoiding risky behaviour may be a more effective way to modify young people’s behaviour than repeated warnings about all the bad things that could happen.

The study, conducted by researchers from University College London and published in the journal Proceedings of the National Academy of Sciences today, involved a study of 52 volunteers aged nine to 26.... Read more »

Long-Lived Proteins : New Research to Characterize Aging Process

by Guillaume Cote-Maurais in United Academics

The majority of cellular proteins are rapidly degraded and replaced with newly synthesized copies, minimizing accumulation of potentially toxic damage and ensuring a functional proteome throughout a cell’s lifetime. Several studies have measured global protein turnover rates in yeast and mammals and reported an average protein half-life of 1.5 hr to 1–2 days, respectively.... Read more »
