Radiographs of Dolly's skeleton show no signs of abnormal osteoarthritis
PA267/17 Original concerns that cloning caused early-onset osteoarthritis (OA) in Dolly the sheep are unfounded, say experts at the University of Nottingham and the University of Glasgow. The team, who published last year's Nottingham Dollies research which showed that the 8 year-old Nottingham 'Dollies' had aged normally, have now published a radiographic assessment of the skeletons of Dolly herself, Bonnie (her naturally conceived daughter) and Megan and Morag (the first two animals to be cloned from differentiated cells).

Discovery of potent parasite protein may lead to new therapeutic options for inflammatory bowel conditions
A single protein from a worm parasite may one day offer new therapeutic options for treating inflammatory bowel diseases like Crohn's or Ulcerative Colitis, that avoid the potentially serious side effects of current immunosuppressant medications. The study, published today , demonstrates the discovery of a distinct new worm protein which mimics a cytokine found in humans, known as transforming growth factor-beta (TGF-β).

New mechanisms of cell death in neurodegenerative disorders
Researchers at King's College London have discovered new mechanisms of cell death, which may be involved in debilitating neurodegenerative disorders, such as Alzheimer's disease and Parkinson's disease. This novel research, published today in Current Biology , could lead to new therapeutic approaches for treating or delaying the progression of neurodegenerative conditions that are currently incurable, if the findings are expanded.

Gastric acid suppressant lansoprazole may target tuberculosis
A cheap and widely used drug, used to treat conditions such as heartburn, gastritis and ulcers, could work against the bacteria that cause tuberculosis (TB), according to new research from UCL and the London School of Hygiene & Tropical Medicine. The study, published today in PLOS Medicine , found that people who used lansoprazole, as opposed to similar drugs omeprazole or pantoprazole, were a third less likely to develop TB.

Atopic eczema: one size does not fit all
Researchers from the UK and Netherlands have identified five distinct subgroups of eczema, a finding that helps explain how the condition can affect people at different stages of their lives. Doctors and patients have long known that the itchy skin condition can affect people in many different ways.

Twisted sex allows mirror-image snails to mate face-to-face, research finds
PA 268/17 A study led by the University of Nottingham has found that differently-coiled types of Japanese land snails should in fact be considered a single species, because - against all odds - they are sometimes able to mate, a result which has implications for the classification of other snails. Although most snails have a right-handed spiralling shell, rare 'mirror-image' individuals have a shell that coils to the left.

Improved method of engineering T-cells to attack cancer
Researchers at Cardiff University have found a way to boost the cancer-destroying ability of the immune system's T-cells, offering new hope in the fight against a wide range of cancers. Using CRISPR genome editing, the team took the genetic engineering of killer T-cells one step further by removing their non-cancer specific receptors and replacing them with ones that would recognise specific cancer cells and destroy them.

’Mini liver tumours’ created in a dish for the first time
Scientists have created mini biological models of human primary liver cancers, known as organoids, in the lab for the first time. In a paper published , the tiny laboratory models of tumours were used to identify a new drug that could potentially treat certain types of liver cancer. Primary liver cancer is the second most lethal cancer worldwide.

Raising ’good’ cholesterol fails to protect against heart disease
Raising so-called 'good' cholesterol by blocking a key protein involved in its metabolism does not protect against heart disease or stroke, according to a large genetic study of 150,000 Chinese adults published in the journal JAMA Cardiology. There are two types of cholesterol in the blood: LDL-C, so-called 'bad' cholesterol, which is carried in low-density lipoproteins (LDL), and HDL-C, so-called 'good' cholesterol which is found in high-density lipoproteins (HDL).

Signalling protein found to drive heart scarring and organ failure
A part of the immune system once thought to prevent organ damage is actually a leading cause of scarring and heart failure, a study has found. Researchers at Imperial College London discovered that a protein called interleukin 11 (IL-11) plays a key role in the scarring process, which in turn causes heart, kidney and liver failure.

Amazonian streams found teeming with fish species are lacking protection
Hundreds of thousands of Amazonian streams are teeming with highly diverse populations of fish species, a new study reveals. Scientists have found that small streams, in areas of the eastern Brazilian Amazon that are a mixture of forest and farmland, contain fauna new to science, as well as very rare species.

Improving clinical trials with machine learning
Machine learning could improve our ability to determine whether a new drug works in the brain, potentially enabling researchers to detect drug effects that would be missed entirely by conventional statistical tests, finds a new UCL study published today in Brain . "Current statistical models are too simple.

It’s (not) complicated: relationships may be simpler than they seem
New research sheds light on how social networks can evolve by showing that complex social patterns observed across the animal kingdom may be simpler than they appear. Image credit: Shutterstock New Oxford University research has shed light on the complexities involved in forming social bonds, and suggests that the process is much simpler than first thought.

Antibiotic Discovery in the Abyss
Combining the innovations of synthetic biology with robotic environmental sampling, a team of University of Bristol researchers are travelling to some of the most 'extreme' environments on Earth, including Atlantic depths of 4.5km, to find new leads which could help in the global fight against antimicrobial resistance.

New DNA antenatal screening for Down’s syndrome is a ’transformational advance’
Scientists at Queen Mary University of London (QMUL) have shown for the first time that it is possible to incorporate DNA analysis into antenatal screening for three serious chromosome disorders, including Down's syndrome, in a way that is far more accurate, and safer and less stressful for mothers.

Tiny silicon probes provide high definition recording of brain activity
A team involving UCL scientists has developed a new device that could revolutionise our understanding of the brain by allowing researchers to map the activity of complex neural networks that control behaviour and decision making, in a way never before possible. The Neuropixels probes are described in a paper .

Height and weight evolved at different speeds in the bodies of our ancestors
The largest study to date of body sizes over millions of years finds a "pulse and stasis" pattern to hominin evolution, with surges of growth in stature and bulk occurring at different times. At one stage, our ancestors got taller around a million years before body mass caught up.

Sheep are able to recognise human faces from photographs
Sheep can be trained to recognise human faces from photographic portraits - and can even identify the picture of their handler without prior training - according to new research from scientists at the University of Cambridge. We've shown that sheep have advanced face-recognition abilities, comparable with those of humans and monkeys Jenny Morton Sheep can be trained to recognise human faces from photographic portraits - and can even identify the picture of their handler without prior training - according to new research from scientists at the University of Cambridge.

Mammals switched to daytime activity after dinosaur extinction
Mammals only started being active in the daytime after non-avian dinosaurs were wiped out about 66 million years ago (mya), finds a new study led by UCL and Tel Aviv University's Steinhardt Museum of Natural History. A long-standing theory holds that the common ancestor to all mammals was nocturnal, but the new discovery reveals when mammals started living in the daytime for the first time.
