Can this sea snail cure herpes?
|
view preview
Australian scientists are creating a new herpes-blocking drug using a protein found in the blood of abalones. If successful, it could prevent the virus from entering human cells, thereby prevent future outbreaks of cold sores.

Peanut allergies could be a thing of the past
|
view preview
New research from the University of Chicago in the US shows that a class of bacteria known as Clostridia can block peanut allergies in mice, and suggests it could be used to treat similar conditions in humans. Clostridia is one of the types of bacteria killed off by antibiotic use in early childhood, and this research supports the emerging theory that increased antibiotic use is one of the factors that has caused food allergies in kids to rise by 50% since 1997.

Is it a mushroom or an animal?
|
view preview
These weird deep-sea animals, namely, Dendrogramma enigmatica and Dendrogramma discoides, discovered off the coast of Tasmania in 1986, have just been classified - and they're like no animal alive today. The animals' mostly non-symmetrical body plan is unique, which means they’re not part of the Bilateria group, one of the main animal groupings that includes humans.

Balding? Try deliberately plucking your hair
|
view preview
While it may sound counter-intuitive, new research suggests that selectively plucking hairs in very close proximity can stimulate some startlingly dense regrowth. The team behind the study, led by researchers at the University of Southern California, demonstrated that by carefully extracting 200 hairs, one-by-one, from the back of a mouse in a specific configuration and density, they could trigger the growth of around 1,200 new hairs in the area - a five-fold increase. The biological mechanism is shown below: While it's very early days, the researchers say their findings, which were reported in the journal Cell, could pave the way for new treatments for balding, or alopecia. ...

Mosquitoes have preferences too
|
view preview
According to a new study published in the journal PLOS One, it was found that identical twins are equally attractive to mosquitoes than fraternal - or non-identical - twins. This correlation lead researchers to conclude that mosquitoes might be making preferential choices based on differences in our DNA. What causes this preferences? While it may be nice to believe that that mosquitoes are attracted to "sweeter blood", it's not true at all. Female mosquitoes - the ones that bite, in order to get protein necessary for egg development - are actually drawn to us by chemical signals related to body odour. ...

Why do our eyes move when we're dreaming?
|
view preview
Scientists have worked out why your eyes move when you’re dreaming. Scientists have known for decades that the rapid eye movements (REMs) that occur during sleep signal that we’re dreaming, but what do the individual eye motions really represent? It’s long been hypothesised that each movement of the eye reflects new visual information in our dreams, and now for the first time researchers have demonstrated that this is actually the case. According to a new study by researchers at Tel Aviv University in Israel, each flick of the eye that occurs during REM sleep accompanies the introduction of a new image in our dream, with the movement essentially acting like a reset function between individual dream "snapshots".

Weird things happen when you stare into someone's eyes
|
view preview
According to a new study conducted out of Italy, staring into another individuals eyes could induce hallucinogenic effects. The experiment is simple: get two individuals to look into each other's eyes for 10 minutes while they are sitting in a dimly lit room. The sensations that ensue resemble mild "dissociation" - a rather vague psychological term for when people lose their normal connection with reality. It can include feeling like the world is unreal, memory loss and odd perceptual experiences, such as seeing the world in black and white Healthy participants said they'd had "... a compelling experience unlike anything they'd felt before", they scored higher on a dissociative states questionnaire than control participants, and 75 per cent ...

Tiniest snails you'll ever see!
|
view preview
Angustopila dominikae is the only known specimen measuring the astounding 0.86 mm in shell height. That means ten of them could fit into the eye of a large sewing needle at the same time! Until now, the smallest known land snail was a thai species measuring about 0.9 millimeters long. Researchers believe that it probably feeds on microorganisms and may be hermaphroditic. However, because the team didn’t recover any DNA, a lot of uncertainly remains. ...

Elephants possess tumour fighting genes that prevent cancer
|
view preview
Having more cells usually puts one at a higher risk for cancer - but not for the elephant. Despite packing 100 times as many cells as humans, this towering animal can keep cancer at bay thanks to extra copies of a tumor-fighting gene. Researchers found that Asian elephants harbor 30 to 40 copies of the gene that encodes the protein p53, one of the most important mechanisms for preventing cancer and maintaining cell division. If cells have DNA damage that could spawn tumors, p53 prevents them from dividing until they make repairs or spurs them to commit suicide. In contrast, humans sport only two copies of the gene for p53, and so does elephants’ closest living relative, the rock hyrax. The extra copies probably accumulated millions of yea ...
