eDNA expands species surveys to capture a more complete picture
- ScienceDaily
- 19/12/31 18:51
Tiny bits of DNA collected from waters off the West Coast allowed scientists to identify more species of marine vertebrates than traditional surveys with trawl nets. They also reflect environmental shifts such as unusual ocean temperatures that affect the organisms present, new research shows.

How bacteria control their cell cycle
- ScienceDaily
- 19/12/31 17:18
Researchers have demonstrated how bacteria coordinate cell division with the replication of their genetic material. In an interdisciplinary study they explain why the current concept of the bacterial cell cycle has to be rewritten.
A new breakthrough in developing effective antimalarial drugs
- ScienceDaily
- 19/12/31 17:18
Parasites in the genus Plasmodium, which cause malaria, are transmitted to humans through bites from infected mosquitoes. The parasites manage to acclimatize to these two completely different hosts because the plasticity of their genome enables them to adapt as necessary. Scientists decided to investigate the epigenetic mechanisms behind this plasticity, in particular DNA methylation. They...
Possible dementia vaccine closer after mice studies
- ScienceDaily
- 19/12/31 17:18
A vaccine to ward off dementia may proceed to clinical trials after successful animal testing. The research is looking to develop effective immunotherapy via a dual vaccine to remove 'brain plaque' and tau protein aggregates linked to Alzheimer's disease. It is showing success in begenic mice models, supports progression to human trials in years to come.
Betrayed by bile: Bile acids help norovirus sneak into cells
- ScienceDaily
- 19/12/31 17:18
Human noroviruses, the leading viral cause of foodborne illness and acute diarrhea around the world, infect cells of the small intestine by piggybacking on a normal cellular process called endocytosis that cells use to acquire materials from their environment.
From crab studies, a broader approach to identifying brain cells
- ScienceDaily
- 19/12/31 17:18
In a new study, a team tests the notion that a cell's identity can be described solely by the genes it expresses. The study advocates a more 'multimodal' approach to defining cell identity.
Combining neurologic and blood pressure drugs reduces breast tumor development in mice
- ScienceDaily
- 19/12/31 17:18
Adding a medication used to treat epilepsy, bipolar disorder and migraines to a blood pressure medicine reversed some aspects of breast cancer in the offspring of mice at high risk of the disease because of the high fat diet fed to their mothers during pregnancy. Conversely, this treatment combination increased breast cancer development in the offspring whose mothers had not been fed a high fat...
The mysterious case of the ornamented coot chicks has a surprising explanation
- ScienceDaily
- 19/12/31 17:18
The American coot is a somewhat drab water bird with gray and black feathers and a white beak, common in wetlands throughout North America. Coot chicks, however, sport outrageously bright orange and red feathers, skin, and beaks. A new study explains how the bright coloring of coot chicks fits in with the reproductive strategy of their less colorful parents.
Objective subtle cognitive difficulties predict amyloid accumulation and neurodegeneration
- ScienceDaily
- 19/12/31 17:18
Researchers report that accumulating amyloid protein occurred faster among persons deemed to have 'objectively-defined subtle cognitive difficulties' (Obj-SCD) than among persons considered to be 'cognitively normal,' offering a potential new early biomarker for Alzheimer's disease.

Novel combination of antibodies leads to significant improvement in cancer immunotherapy
- ScienceDaily
- 19/12/30 21:30
The simultaneous use of antibodies based on two differing mechanisms of action leads to a more effective destruction of tumors. This has been demonstrated by a study in animal models by medical oncologists and scientists. Patients who do not respond to current immunotherapy options could benefit most from this new treatment.
Life could have emerged from lakes with high phosphorus
- ScienceDaily
- 19/12/30 21:30
Life as we know it requires phosphorus, and lots of it. But phosphorus is scarce. A new study reports that certain types of carbonate-rich lakes, which could have formed on early Earth, have the right chemistry to keep phosphorous levels high and available to organisms.
Findings strengthen link between vitamin E acetate and vaping-associated lung injuries
- ScienceDaily
- 19/12/30 18:01
New research strengthens prior findings on the link between vitamin E acetate and EVALI (E-cigarette or vaping product use-associated lung injury).
Children who drank whole milk had lower risk of being overweight or obese
- ScienceDaily
- 19/12/30 16:48
Researchers analyzed 28 studies from seven countries that explored the relationship between children drinking cow's milk and the risk of being overweight or obese.
Many younger patients with stomach cancer have a distinct disease
- ScienceDaily
- 19/12/30 16:48
Many people under 60 who develop stomach cancer have a 'genetically and clinically distinct' disease, new research has discovered. Compared to stomach cancer in older adults, this new, early onset form often grows and spreads more quickly, has a worse prognosis, and is more resistant to traditional chemotherapy treatments, the study finds.
Learning from the bears
- ScienceDaily
- 19/12/30 16:48
Grizzly bears spend many months in hibernation, but their muscles do not suffer from the lack of movement. Researchers report on how they manage to do this. The grizzly bears' strategy could help prevent muscle atrophy in humans as well.
Scientists link La Niña climate cycle to increased diarrhea
- ScienceDaily
- 19/12/30 16:47
A study finds that spikes in cases of life-threatening diarrhea in young children are associated with La Niña climate conditions. The findings could provide the basis for an early-warning system that would allow public health officials to prepare for periods of increased diarrhea cases as long as seven months ahead of time.
How do conifers survive droughts? Study points to existing roots, not new growth
- ScienceDaily
- 19/12/30 16:47
As the world warms, a new study is helping scientists understand how coniferous forests may respond to drought. The research addresses a classic question in the field: When conditions are dry for long periods of time, do trees survive by growing new roots to tap water sources, or by relying on established roots that already go deep?
Long-dormant disease becomes most dominant foliar disease in New York onion crops
- ScienceDaily
- 19/12/30 16:47
Until recently, Stemphylium leaf blight has been considered a minor foliar disease as it has not done much damage in New York since the early 1990s. However, onion growers in New York have recently seen an increase in the dieback of their crops, and scientists were surprised to discover that SLB was the cause.
North Atlantic Current may cease temporarily in the next century
- ScienceDaily
- 19/12/30 14:48
The North Atlantic Current transports warm water from the Gulf of Mexico towards Europe, providing much of north-western Europe with a relatively mild climate. However, scientists suspect that meltwater from Greenland and excessive rainfall could interfere with this ocean current. Simulations showed that there is a 15 percent likelihood that there will be a temporary change in the current in the...

Using deep learning to predict disease-associated mutations
- ScienceDaily
- 19/12/27 16:49
A research team implemented a robust deep learning approach to predict disease-associated mutations of the metal-binding sites in a protein. This is the first deep learning approach for the prediction of disease-associated metal-relevant site mutations in metalloproteins, providing a new platform to tackle human diseases.
New insights into the earliest events of seed germination
- ScienceDaily
- 19/12/27 16:49
Plant seeds can store their energy in a dry state for years, only to suddenly release it and germinate. How is energy in the seed made available? How can energy metabolism be started early and efficiently? An international team of researchers has discovered that thiol redox switches play a key role in kick-starting the energy metabolism.
