NASA UFO team calls for higher quality data in first public meeting
The truth may be out there about UFOs, or what the government currently calls “unidentified anomalous phenomena” (UAPs). But finding it will require collecting data that are more rigorous than the anecdotal reports that typically fuel the controversial sightings, according to a panel of scientists,
appointed by NASA
to advise the agency on the topic, that held its first...
Revealing the secrets of freshwater streams
Beneath the surface of a freshwater stream, animals, plants, fungi, and microorganisms create complex patterns of biodiversity. Brooke Penaluna, research fisheries biologist at the USDA Forest Service Pacific Northwest Research Station, studies these dynamics, which can be complicated.
New study quantifies the power of bipartisan coalitions
After weeks of tense speculation over a looming financial catastrophe, should the U.S. default on its debts, House Majority Leader Kevin McCarthy and President Biden are finalizing terms for a bipartisan agreement to raise the debt ceiling. While it is clear that a bipartisan deal is necessary for legislative action during divided government, it is less clear whether bipartisanship is similarly...
When the media believe that a firm is really green
When firms make their environmental policies public, they can get favorable media coverage only if their narrative carefully articulates signals of conformity (actions aimed at complying with existing norms) and distinctiveness (the adoption of a recognizably uncommon behavior).
When countries cut taxes for new ideas, capital investments rise
Countries that offer tax breaks for corporate innovation realize greater economic growth than those with no such policies, according to a study from The University of Texas at Austin.
Study leads to milestone advances in understanding lethal bronzing of palm trees
Palm trees infected with lethal bronzing disease emit signals that warn nearby healthy palms of the threat. Those healthy palms produce their own defense that University of Florida scientists one day hope to harness to protect palms against the disease.
Short-lived solutions for tall trees in Chile's megadrought
For more than a decade, forests across much of Chile have been experiencing a megadrought, its effects overprinted on an already warming and drying climate. High in the Andes, stands of giant Nothofagus obliqua trees, also known as roble or southern beech, are stretching themselves to survive—and bucking a global forest trend.
Countries tussle at 'rocky' global plastic talks
Negotiators charged with hammering out a global treaty to end plastic pollution were warned there was "no time to lose" on Wednesday, after progress was slowed by two days of procedural debates that campaigners blamed on large producer countries.
Once hostile, NASA holds first public meeting on UFOs
The truth is out there—but we're going to need to look harder.
Firefighters in east Canada battle 'unprecedented' blazes
Firefighters on Wednesday faced a grueling uphill battle against wildfires in Canada's Nova Scotia province, including one threatening suburbs of Halifax.
Triple-whammy of cyclones, a 1-in-200-year event, drove Italy's deadly flooding, scientists say
A rare, triple-whammy of cyclones drove the deadly flooding that devastated much of northern Italy this month, but scientists said Wednesday that climate change doesn't seem to be to blame for the intense rainfall.
AI crop predictor aids Africa's crisis planning
An artificial intelligence (AI) tool is using satellite remote sensing and machine learning to predict agricultural yields of key crops across Africa, to help mitigate the harms of climate change and other crises, its developers say.
Social networks key to water management and sanitation in the Pacific, says study
A Griffith-led study has found that traditional and digital social networks are key to improving community water management and sanitation in the Pacific.
Improving precision of planning results in resilient forests
A new dissertation on forest industrial production systems, from researcher Per Nordin at Linnaeus University, reveals that successful regeneration measures are crucial for sustainable forestry. To ensure successful plant establishment, it is important to make decisions based on factors at regional, stand, and microenvironment levels.
Research is the first to unlock the secret of microbial slime
The slimy outer layer of fungi and bacteria known as the "extracellular matrix," or ECM, has the consistency of jelly and acts as a protective and envelope layer. But, according to a recent study in the journal iScience, led by the University of Massachusetts Amherst in collaboration with Worcester Polytechnic Institute, the ECM of some microbes only gels when oxalic acid or other simple acids are...
Exploring how we've underestimated Earth's heat storage
The increase in anthropogenic greenhouse gases in the atmosphere prevents the emission of heat into space. As a result, the Earth constantly absorbs more heat through solar radiation than it can give back off through thermal radiation.
Migratory bats tracked for the first time ever using new algorithm
For the first time ever, researchers can track the movements of bats with the help of a brand new algorithm utilizing radar technology, created by the University of Haifa and Tel Aviv University.
Leveling up scanning electron microscope measurements for chip manufacturing
Researchers from the National Institute of Standards and Technology (NIST) and KLA Corporation, a provider of inspection and measurement systems for the semiconductor and related industries, have improved the accuracy of scanning electron microscope (SEM) measurements. Used for process control applications in semiconductor manufacturing, SEMs help ensure high-yield production of functional,...
Baseball reveals that specialists excel after leaving comfort zones
Venturing out of one's comfort zone to perform a task—and then performing poorly in that task, such as a baseball pitcher trying to hit—can lead to better performance when returning to one's specialty, new research suggests.
One spacecraft could visit all of Saturn's inner large moons
If you've ever played Kerbal Space Program, you know how difficult it can be to get your spacecraft into the orbit you want. It's even more difficult in real life. This is why it's pretty impressive to see a proposal to study all of Saturn's large inner moons in one go.
NASA UFO panel says stigma, lack of data are problems when studying 'unidentified aerial phenomena'
The first public meeting of a NASA panel studying what the government calls "unidentified aerial phenomena," commonly known as UFOs, kicked off on Wednesday to discuss its findings since it formed last...
NASA researchers detect tsunamis by their rumble in the atmosphere
New hazard-monitoring technology uses GPS signals to go wave-hunting in the Pacific Ring of Fire. GUARDIAN's long-term objective is to augment early warning systems.
Gene engineered cell therapy developed to target brain metastatic melanomas

Overall survival for patients with melanoma that has spread to the brain is only four to six months. Immunotherapies, which harness the power of the immune system to attack cancer cells, have garnered excitement in recent years for their potential to revolutionize the treatment of metastatic melanomas, but results from early clinical studies indicate that the prognosis for most patients remains...
