Water formation on the moon

For the first time, a cross-disciplinary study has shown chemical, physical, and material evidence for water formation on the moon. Two teams from the University of Hawaiʻi at Mānoa collaborated on the project: physical chemists at the UH Mānoa Department of Chemistry's W.M. Keck Research Laboratory in Astrochemistry and planetary scientists at the Hawai'i Institute of Geophysics and Planetology (HIGP).

Stellar waltz with dramatic ending

Astronomers at the University of Bonn and their colleagues from Moscow have identified an unusual celestial object. It is most likely the product of the fusion of two stars that died a long time ago. After billions of years circling around each other these so-called white dwarfs merged and rose from the dead. In the near future, their lives could finally end—with a huge bang. The researchers are now presenting their findings in the journal Nature.

Formation of the moon brought water to Earth

The Earth is unique in our solar system: It is the only terrestrial planet with a large amount of water and a relatively large moon, which stabilizes the Earth's axis. Both were essential for Earth to develop life. Planetologists at the University of Münster (Germany) have now been able to show, for the first time, that water came to Earth with the formation of the Moon some 4.4 billion years ago. The Moon was formed when Earth was hit by a body about the size of Mars, also called Theia. Until now, scientists had assumed that Theia originated in the inner solar system near the Earth. However, researchers from Münster can now show that Theia comes from the outer solar system, and it delivered large quantities of water to Earth. The results are published in the current issue of Nature Astronomy.

Seven things we've learned about Ultima Thule, the farthest place visited by humans

Rocket man: LSU Mechanical Engineering alumnus Max Faget remembered 50 years after moon landing

Apollo 11 Astronaut Neil Armstrong is rightfully remembered for taking man's first steps on the moon nearly 50 years ago on June 20, 1969. Less well known, perhaps, is LSU Mechanical Engineering alumnus Maxime "Max" Faget, who designed the spacecraft responsible for that "giant leap for mankind."

Technology news

CycleMatch: a new approach for matching images and text

Researchers at Leiden University and the National University of Defense Technology (NUDT), in China, have recently developed a new approach for image-text matching, called CycleMatch. Their approach, presented in a paper published in Elsevier's Pattern Recognition journal, is based on cycle-consistent learning, a technique that is sometimes used to train artificial neural networks on image-to-image translation tasks. The general idea behind cycle-consistency is that when transforming source data into target data and then vice versa, one should finally obtain the original source samples.

The man who is aging too fast

Nobuaki Nagashima was in his mid-20s when he began to feel like his body was breaking down. He was based in Hokkaido, the northernmost prefecture of Japan, where for 12 years he had been a member of the military, vigorously practicing training drills out in the snow. It happened bit by bit—cataracts at the age of 25, pains in his hips at 28, skin problems on his leg at 30.

Using 3-D to test personalised treatments in five days

Why doesn't the same treatment work in the same way for every patient? How can a drug's performance be optimised without causing side effects due to an excessive dosage? In an attempt to answer these questions, researchers at the University of Geneva (UNIGE), Switzerland, have devised a cell co-culture platform that reproduces a patient's tumour structure in 3-D. The scientists can use it to test several drugs or their combinations at different stages of the tumour's development. They now need only five days to identify which treatment will be most effective for a particular case, and the combination can then be translated for clinical practice. These results are highly promising for the future of personalised medicine, and you can read all about the outcomes in the journal Scientific Reports.

The scandal that should force us to reconsider wellness advice from influencers

Patients who lose significant weight before a transplant are at higher risk of dying

Unexpected weight loss can be the sign of a serious health problem, especially in kidney transplant patients whose body systems are already under duress. But a new study out of Drexel University suggests that even planned and advised weight loss could also be dangerous for kidney transplant candidates if it's not closely monitored.

What happens to young adults after a first heart attack?

Heart attacks among adults younger than 50 years of age are on the rise. In fact, the proportion of very young people has been increasing, rising by 2 percent each year for the last 10 years, according to a team of investigators a Brigham and Women's Hospital who are focused on studying heart attacks among young adults. The research team is now investigating why, by evaluating both risk factors and outcomes for this population in order to help prevent heart attacks in the first place. In a paper published in the Journal of the American College of Cardiology, the team reports on the prevalence of familial hypercholesterolemia (FH), a genetic disorder that results in high cholesterol, and outcomes for patients. Investigators have found that nearly one in 10 patients who suffer a first heart attack before age 50 had FH, and many continued having elevated cholesterol levels a year after their first heart attack. Many were not on a statin therapy before their first heart attack, highlighting opportunities for prevention and more aggressive treatment for those at risk.

Insights into brigatinib's rare side effects may help more lung cancer patients benefit from the drug

Brigatinib is a next-generation ALK inhibitor that earned FDA approval in 2017 as a second-line therapy after treatment with crizotinib for ALK-positive non-small cell lung cancer. Recently, clinical trial results published in the New England Journal of Medicine and presented at the 2018 World Conference on Lung Cancer show its promise as a first-line therapy. However, while brigatinib is commonly well-tolerated, in about 3% of cases, patients report experiencing shortness of breath within hours of starting treatment. With severe symptoms or if even mild symptoms occur after stopping and then restarting the drug, the manufacturer's guidelines suggest permanently ceasing use. Now a study by researchers at Columbia University, University of California San Diego, and University of Colorado Cancer Center, published this morning in the Journal of Thoracic Oncology, offers insight into the seriousness and duration of these symptoms, and suggests an alternative treatment strategy that could allow more patients to benefit from this drug.

Widespread testing, treatment of Hepatitis C in U.S. prisons improves outcomes

At current drug prices, testing all persons entering prison for Hepatitis C, treating those who have at least 12 months remaining in their sentence, and linking individuals with less than 12 months in their sentence to care upon their release would result in improved health outcomes. Published in Clinical Infectious Diseases, researchers found that these approaches provide the best value-for-money compared to not testing or treating any prisoners, or only testing and treating prisoners at high risk of Hepatitis C (HCV). While cost-effective, however, the data also show that these approaches would place a large cost burden on the correctional system.

After GWAS studies, how to narrow the search for genes?

Genome-wide association studies (GWAS) look at large populations to find genes that contribute to common, multi-gene traits like height or obesity. These comprehensive investigations frequently turn up large numbers of tiny genetic variations that show up more often in people who are tall, obese, etc. But this association doesn't mean the variant actually helps cause the trait; it could just be going along for the ride.

New opioid speeds up recovery without increasing pain sensitivity or risk of chronic pain

Morphine and other opioid-based painkillers are very effective at treating pain initially, but studies have shown that the drugs can make patients more pain-sensitive, prolonging their discomfort and increasing their risks of developing chronic pain.

Nerve fibers in skin are involved in initiating neurofibromas in patients with disfiguring Neurofibromatosis 1

A study published today in PLOS ONE discovered the origin of severely disfiguring masses of cells, called neurofibromas, that gradually develop throughout the skin of patients afflicted with Neurofibromatosis 1 (NF1). The discovery consisted of micro-lesions that contained small pathological clusters of nerve fibers and associated Schwann cells that proliferate to form the bulk of the disfiguring neurofibromas.

Studies find no yield benefit to higher plant populations

As seed prices rise, growers must be increasingly mindful of the density and configuration of cotton in their fields. However, current cotton plant population recommendations aren't always helpful or based on the latest research. Experts often offer guidance, rather than direct answers, and discuss both seeding rates and plant population, which can be confusing. Experts also recommend seeding in excess to account for inevitable seed loss. The most common plant population recommendation is 33,000 plants per acre.

First report of powdery mildew on phasey bean in Florida could spell trouble for papaya
