Non-invasive brain stimulation helps to ease tremors
A team involving UCL researchers have used electrical pulses to help suppress the tremors typically found in conditions such as Parkinson's disease. In a paper published , the scientists report their new way of suppressing the brain waves underpinning tremors, without the need for invasive techniques.

Counting elephants from space
Counting elephants from space
Satellite images processed with the help of computer algorithms devised at the University of Bath are a promising new tool for surveying endangered wildlife. Last updated on Friday 22 January 2021 For the first time, scientists have successfully used satellite cameras coupled with deep learning to count animals in complex geographical landscapes, taking conservationists an important step forward in monitoring populations of endangered species.

New starfish-like fossil reveals evolution in action
New starfish-like fossil reveals evolution in action
Researchers from the University of Cambridge have discovered a fossil of the earliest starfish-like animal, which helps us understand the origins of the nimble-armed creature.

Eye tests predict Parkinson’s-linked cognitive decline 18 months ahead
Simple vision tests can predict which people with Parkinson's disease will develop cognitive impairment and possible dementia 18 months later, according to a new study by UCL researchers. The study, published in Movement Disorders , adds to evidence that vision changes precede the cognitive decline that occurs in many, but not all, people with Parkinson's.

New biomaterials can be ’fine-tuned’ for medical applications
Researchers in the UK and the United States have succeeded in ‘fine tuning' a new thermoplastic biomaterial to enable both the rate at which it degrades in the body and its mechanical properties to be controlled independently. The material, a type of polyester, has been designed for use in soft tissue repair or flexible bioelectronics by a team at the University of Birmingham in the UK and Duke University in the US.

Dinosaur-era sea lizard had teeth like a shark
New study identifies a bizarre new species suggesting that giant marine lizards thrived before the asteroid wiped them out 66 million years ago. Last updated on Monday 18 January 2021 A new species of mosasaur - an ancient sea-going lizard from the age of dinosaurs - has been found with shark-like teeth that gave it a deadly slicing bite.

Genetic factors involved in shaping the composition of the human gut microbiome, finds international research team
Human genes have an impact on shaping our gut ecosystem according to new evidence from the international MIBioGen consortium study involving more than 18,000 people. The findings, led by the University Medical Center Groningen, Netherlands and involving researchers at the University of Bristol, are published today [18 January] .

New insight into why breastfed babies have improved immune systems
Research led by the University of Birmingham and Birmingham Women's and Children's NHS Foundation Trust has revealed new insight into the biological mechanisms of the long-term positive health effects of breastfeeding in preventing disorders of the immune system in later life. Breastfeeding is known to be associated with better health outcomes in infancy and throughout adulthood, and previous research has shown that babies receiving breastmilk are less likely to develop asthma, obesity, and autoimmune diseases later in life compared to those who are exclusively formula fed.

Foraging humans, mammals and birds who live in the same place behave similarly
Foraging humans find food, reproduce, share parenting, and even organise their social groups in similar ways as surrounding mammal and bird species, depending on where they live in the world, new research has found. The study , shows environmental factors exert a key influence on how foraging human populations and non-human species behave, despite their very different backgrounds.

Following the hops of disordered proteins could lead to future treatments of Alzheimer’s disease
Study shows how to determine the elusive motions of proteins that remain disordered. The constant motion of amyloid-beta is one of the reasons it's been so difficult to target - it's almost like trying to catch smoke in your hands Michele Vendruscolo Researchers from the University of Cambridge, the University of Milan and Google Research have used machine learning techniques to predict how proteins, particularly those implicated in neurological diseases, completely change their shapes in a matter of microseconds.

Different mutations in one gene can cause different types of diseases
Leading cancer experts at the University of Birmingham have solved a long-standing question of how various types of mutations in just one gene cause different types of diseases. A team of scientists at the University's Institute of Cancer and Genomic Sciences , led by Professor Constanze Bonifer, studied a gene known as RUNX1, which is responsible for providing instructions for the development of all blood cells and is frequently mutated in blood cancers.

Mathematics explains how giant ’whirlpools’ form in developing egg cells
The swirling currents occur when the rodlike structures that extend inward from the cells' membranes bend in tandem, like stalks of wheat caught in a strong breeze, according to a study from the University of Cambridge and the Flatiron Institute. The mechanism of the swirling instability is disarmingly simple, and the agreement between our calculations and experimental observations supports the idea that this is indeed the process at work in fruit fly egg cells Raymond Goldstein Egg cells are among the largest cells in the animal kingdom.

Ancient DNA reveals secrets of Game of Thrones wolves
For fans of the TV show Game of Thrones, dire wolves are often seen as mysterious iconic legends. Now, for the first time, an international team led by Durham University and colleagues in Australia, Germany and the US, have analysed ancient DNA from dire wolves to reveal a complex history of these ice age predators.

Teeth functioned and evolved in giant mega-sharks
A pioneering study by University of Bristol researchers finds that the evolution of teeth in the giant prehistoric shark Megalodon and its relatives was a by-product of becoming huge, rather than an adaptation to new feeding habits. The iconic extinct Megalodon was the largest shark to ever roam the seas.

Climate change damage to the homes of clownfish affects their physiology
The metabolism of clownfish - or anemonefish - decreases when their sea 'homes' are damaged by climate change, according to a new study. The research - led by an international team of scientists from the University of Glasgow and CRIOBE, and published today in Functional Ecology - found that exposure to bleached coral reefs can have a negative effect on the physiology and growth of anemonefish.

Study identifies genetic changes likely to have enabled SARS-CoV-2 to jump from bats to humans
A new study, involving the University of Cambridge and led by the Pirbright Institute, has identified key genetic changes in SARS-CoV-2 - the virus that causes COVID-19 - that may be responsible for the jump from bats to humans, and established which animals have cellular receptors that allow the virus to enter their cells most effectively.

Deadly parasites create unique cellular structures to survive
Scientists have solved a key parasitic puzzle, revealing the unique and complex structures toxoplasmosis and malaria parasites make in order to survive in different hosts. The new study, led by the University of Glasgow in collaboration with the University of Stockholm, and published , details how certain parasites can create unique cellular structures to control how they create energy and thus survive in different hosts.

New COVID-19 test gives positive result in just a few minutes
A new COVID-19 test that reduces testing time from 30 minutes to less than five and delivers accurate results has been developed by researchers at the University of Birmingham. The researchers believe their method could deliver a test that is not only fast but also sufficiently sensitive. The test does not require samples to be treated at high temperatures, and it can be performed using standard laboratory equipment, making it readily deployable.
