For the first time, scientists have introduced minuscule tracking devices directly into the interior of mammalian cells, giving an unprecedented peek into the processes that govern the beginning of development.
This work on one-cell embryos is set to shift our understanding of the mechanisms that underpin cellular behaviour in general, and may ultimately provide insights into what goes wrong in ageing and disease.
Glass frogs are well known for their see-through skin but, until now, the reason for this curious feature has received no experimental attention.
A team of scientists from the University of Bristol, McMaster University, and Universidad de Las Américas Quito, sought to establish the ecological importance of glass frog translucency and, in doing so, have revealed a novel form of camouflage.
The world's deep oceans are warming at a slower rate than the surface, but it's still not good news for deep-sea creatures according to an international study.
The research, led by University of Queensland PhD student Isaac Brito-Morales, looked at how ocean life was responding to climate change.
"We used a metric known as climate velocity which defines the likely speed and direction a species shifts as the ocean warms," Mr Brito-Morales said.
Global warming is causing species to search for more temperate environments in which to migrate to, but it is marine species - according to the latest results of a Franco-American study mainly involving scientists from the CNRS, Ifremer, the Université Toulouse III - Paul Sabatier and the University of Picardy Jules Verne (1) - that are leading the way by moving up to six times faster towards the poles than their terrestrial congeners.
The diagnosis of cancer in a child can be devastating to parents and other loved ones, but in a recent study from Denmark, having a child with cancer did not appear to impact parents' risk of separation or divorce or affect future family planning. The findings are published early online in CANCER, a peer-reviewed journal of the American Cancer Society (ACS).
Varennes, May 25 2020 - Australian and Canadian researchers led by Prof David J. Moss at Swinburne University of Technology and honorary professor at the Institut National de la Recherche Scientifique (INRS) was able to achieve world record-high data transmission over 75 km of standard optical fibre using a powerful class of micro-comb called soliton crystals.
(Vienna, Sunday, 24 May, 2020) Stroke survivors suffering from the burden of combined sleep-wake disturbances are more likely to have another stroke or serious cardio- or cerebrovascular event compared to those without sleep-wake disturbances, according to the results of a scientific study presented today at the European Academy of Neurology (EAN) Virtual Congress.
The beetles of family Erotylidae (Coleoptera: Cucujoidea) are morphologically and biologically diversified into six subfamilies, 10 tribes, and over 3,500 species. The tribe Toramini includes 4 genera and is distributed worldwide. Although, the biology of this group is poorly investigated, Leschen (2003) reported that larvae of Toramus and Loberoschema retain exuviae on their abdomen throughout larval development.
The great white shark is one of the most charismatic, but also one of the most infamous sharks. Despite its importance as top predator in marine ecosystems, it is considered threatened with extinction; its very slow growth and late reproduction with only few offspring are - in addition to anthropogenic reasons - responsible for this.
Valleytronics gives rise to valley current, a stable, dissipationless current which is driven by a pseudo-magnetic field, Berry curvature. This gives rise to valletronics based information processing and storage technology. A pre-requisite for the emergence of Berry curvature is either a broken inversion symmetry or a broken time-reversal symmetry. Thus two-dimensional materials such as transition metal dichalcogenides and gated bilayer graphene are widely studied for valleytronics as they exhibit broken inversion symmetry.
Twin-to-twin transfusion syndrome (TTTS) occurs in around 10-15% of pregnancies with twins that share the same placenta. Typically, this syndrome appears before 24 weeks' gestation due to abnormal vascular communications located on the surface of the placenta. As a result, blood circulation is not balanced between the two twins, dramatically decreasing their chances of survival.
Due to the spread of antibiotic-resistant strains of Neisseria gonorrhoeae, existing treatments for gonorrhea, the sexually transmitted infection caused by the bacterium, are no longer effective. In the absence of a vaccine, there is an urgent need to develop novel treatment options.
Magnesium dimer (Mg2) is a fragile molecule consisting of two weakly interacting atoms held together by the laws of quantum mechanics. It has recently emerged as a potential probe for understanding fundamental phenomena at the intersection of chemistry and ultracold physics, but its use has been thwarted by a half-century-old enigma--five high-lying vibrational states that hold the key to understanding how the magnesium atoms interact but have eluded detection for 50 years.
Methylation (namely addition of a methyl group) of arginine amino acid residues of proteins is a post-translational modification (PTM) catalyzed by a family of nine enzymes called Protein Arginine Methyl-Transferases (PRMTs).
Researchers from Monash, Swinburne and RMIT universities have successfully tested and recorded Australia's fastest internet data speed, and that of the world, from a single optical chip - capable of downloading 1000 high definition movies in a split second.
Published in the prestigious journal Nature Communications, these findings have the potential to not only fast-track the next 25 years of Australia's telecommunications capacity, but also the possibility for this home-grown technology to be rolled out across the world.
