How Venus Flytraps also Snap
How Venus Flytraps also Snap
Venus flytraps are known for the fact that their catching leaves close in a flash when unsuspecting prey touch highly sensitive trigger hairs twice in a row. A team of researchers from ETH Zurich and the University of Zurich has now discovered a new snap mechanism. The Venus flytrap ( Dionaea muscipula ) is perhaps the most well-known carnivorous plant.

Whale skulls are wonkier than ever
The skulls of toothed whales have become more asymmetric over time, according to a new study led by UCL and the Natural History Museum in London. The team also found that early ancestors of living whales had little cranial asymmetry and likely were not able to echolocate, in the findings published in BMC Biology .

Transplantable lab-grown organs move a step closer
Transplantable lab-grown organs move a step closer
A liver organoid developed at EPFL offers new promise in transplantation and the study of liver disease. Biologists and bioengineers at EPFL have designed a new method for growing simplified human mini-livers. Their process is a potentially important breakthrough in the quest for transplantable lab-grown tissues.

Parasitic worms use their keen senses to wriggle through their hosts
Parasitic filarial nematodes infect hundreds of millions of people, causing diseases such as river blindness and lymphatic filariasis, which can lead to elephantiasis, a severe swelling of the limbs. Mosquitoes spread the parasitic worms, which engage in sophisticated migrations within their insect and mammal hosts.

Protective Alzheimer’s gene and develop rapid drug-testing platform
A gene has been discovered that can naturally suppress the signs of Alzheimer's disease in human brain cells, in research involving UCL and led by Queen Mary University of London. The scientists have also developed a new rapid drug-screening system for treatments that could potentially delay or prevent the disease, they report in Molecular Psychiatry.

Researchers solve a 50-year-old enzyme mystery
Advanced herbicides and treatments for infection may result from the unravelling of a 50-year-old mystery by University of Queensland researchers. The research team, led by UQ's Professor Luke Guddat , revealed the complete three-dimensional structure of an enzyme, providing the first step in the biosynthesis of three essential amino acids - leucine, valine and isoleucine.

Sodium found to regulate the biological clock of mice
A new study from McGill University shows that increases in the concentrations of blood sodium can have an influence on the biological clock of mice, opening new research avenues for potentially treating the negative effects associated with long distance travel or shift work. The findings a professor in McGill's Department of Neurology-Neurosurgery, are the first to show that injecting mice with a salt solution leads to the activation of neurons associated with the brain's master circadian clock - the suprachiasmatic nucleus (SCN).

Which vaccine types are in the running against COVID-19?
The world is eagerly awaiting one or more vaccines to protect us against the SARS-CoV-2 virus. We will only be able to fully resume our lives when we are immune to the infection.

Baboons do not view researchers as neutral
Baboons who are used to researcher presence are less tolerant than we thought, according to a new study by our anthropologists. It had been widely presumed that researchers can use habituation to remove the fear that study animals have towards them, leading to animals ignoring people at close range.

License agreement creates golden opportunity for cancer diagnostic technology
A novel rapid cancer diagnostic technology with the potential to quickly and easily detect cancer has been licensed for further development. The methylscape technology which uses gold sensors to determine if 3D nanostructures of cancer DNA are present in blood or biopsy tissue was developed at The University of Queensland's Australian Institute for Bioengineering and Nanotechnology (AIBN).

Scientists pinpoint surprising new function for histones
FINDINGS UCLA scientists have identified a new function for histones, the spool-shaped proteins that regulate gene expression and help pack long strands of DNA into cells. The resulting matrix, called chromatin, provides the structural foundation for chromosomes. In a surprising finding that received more than 1,400 “likes” and more than 600 shares on Twitter within the first several days after the study was published, the researchers discovered that histones also function as enzymes that convert copper into a form that can be used by the body's cells.

Polynesians, Native Americans made contact before European arrival, genetic study finds
Deep-genome analyses conducted by Stanford Medicine researchers and their collaborators have settled a long-brewing controversy about whether ancient Polynesians and Native Americans had contact. Through deep genetic analyses, Stanford Medicine scientists and their collaborators have found conclusive scientific evidence of contact between ancient Polynesians and Native Americans from the region that is now Colombia - something that's been hotly contested in the historic and archaeological world for decades.

Scientists form spinout to launch rapid Covid-19 virus test | University of Oxford
Scientists form spinout to launch rapid Covid-19 virus test | University of Oxford
The Covid-19 pandemic demands availability of highly accessible and rapid testing around the world to detect SARS-CoV-2 and enable countries to emerge from lockdown with confidence.áScientists from the 's Department of Engineering Science and Oxford Suzhou Centre for Advanced Research (OSCAR) have developed a rapid test which detects the presence of virus which could be adapted for use in settings ranging from community care, schools, airports or home self-testing.

Deconstructing glioblastoma complexity reveals its pattern of development
Study identifies rapidly dividing cancer stem cells that can respond to new therapies Brain cancers have long been thought of as being resistant to treatments because of the presence of multiple types of cancer cells within each tumor. A new study uncovers a cancer cell hierarchy that originates from a single cancer cell type, which can be targeted to slow cancer growth.

Delirium, rare brain inflammation and stroke linked to Covid-19
Neurological complications of Covid-19 can include delirium, brain inflammation, stroke and nerve damage, finds a new UCL and UCLH-led study. Published in the journal Brain , the research team identified one rare and sometimes fatal inflammatory condition, known as ADEM, which appears to be increasing in prevalence due to the pandemic.

Analysis: How studying fruit flies might help us prevent age-related hearing loss in humans
Scientists at UCL have discovered sets of regulatory genes in fruit flies, which are responsible for maintaining healthy hearing. Professor Joerg Albert (UCL Ear Institute) explains how the findings could potentially lead to treatments for age-related hearing loss in humans. Hearing loss is a common age-related ailment, affecting nearly one in every three people over the age of 65.

Women’s egg quality dependent on metabolic factors
Increasing the levels of a chemical found in all human cells could boost a woman's fertility and help select the best eggs for IVF, according to University of Queensland research. In the world's most in-depth study of the final steps of egg maturation, the quality of a woman's eggs was found to be significantly dependent on the important metabolic coenzyme called nicotinamide adenine dinucleotide (NAD+).

The IRB discovers the activation mechanism of the "police patrol" cells of our immune system
Nearly 200 billion na´ve T cells continuously patrol the human body in a dormant state, prepared to respond to potential threats. An international group of researchers, led by Dr. Roger Geiger of the Institute for Research in Biomedicine (IRB, affiliated to USI), demonstrated how these cells sustain a constant state of preparedness.

Enzymes as double agents: new mechanism discovered in protein modification
Enzymes as double agents: new mechanism discovered in protein modification
Proteins are the workers in a cell and, as the “basic element of life”, are responsible for the most widely varying metabolic processes. In plants, for example, they take on an important function in photosynthesis. In order to be able to work purposefully, proteins change their chemical form after they have been produced in a cell - for example, through protein acetylation, when an acetyl group is transferred to the protein.
