NASA and SpaceX are going ahead with plans to bring NASA astronauts Doug Hurley and Bob Behnken home from the International Space Station for a splashdown this weekend, even though Hurricane Isaias is heading for Florida's Atlantic coast. Fortunately, SpaceX's Dragon capsule is heading for waters off Florida's other coast. NASA said weather conditions are all systems go for the...
New results achieved by combining big data captured by the Subaru Telescope and the power of machine learning have discovered a galaxy with an extremely low oxygen abundance of 1.6% solar abundance, breaking the previous record of the lowest oxygen abundance. The measured oxygen abundance suggests that most of the stars in this galaxy formed very recently.
Provider-focused P2P marketing communications increase consumers' likelihood of purchase, app download, and willingness to pay.
The first US astronauts to reach the International Space Station on an American spacecraft in nearly a decade prepared Saturday for their return home, which is tentatively on schedule for the weekend despite the arrival of Hurricane Isaias off Florida. "Now is the entry, descent and splashdown phase after we undock, hopefully a little bit later today," Doug Hurley, one of the two astronauts, said...
Emily and Laurence Alison specialise in communication and co-operation with criminal suspects. But their methods work in the home and at work, too“The more you push someone, the more they close up,” say Emily and Laurence Alison, a husband-and-wife psychology team. “The hungrier you are for information, the harder it will be to get that out of someone. But give the person a choice about what...
The tech giants’ latest machine-learning system comes with both ethical and environmental costsUnless you’ve been holidaying on Mars, or perhaps in Spain (alongside the transport secretary), you may have noticed some fuss on social media about something called GPT-3. The GPT bit stands for the “generative pre-training” of a language model that acquires knowledge of the world by...
The evolutionary biologist on data manipulation, fake news, and the importance of using science as a lie detectorCarl Bergstrom is a professor of evolutionary biology at the University of Washington in Seattle. More than a decade ago he conducted research on the role of government in pandemic planning, and has been a trenchant critic of the current response. He is the co-author with his colleague...
Scientists have discovered the tool our stone-age ancestors used to manufacture twine – a milestone in technological developmentForty thousand years ago, a stone-age toolmaker carved a curious instrument from mammoth tusk. Twenty centimetres long, the ivory strip has four holes drilled in it, each lined with precisely cut spiral incisions.The purpose of this strange device was unclear when it...
Urgent annual cash injection of £650m needed for cardiovascular conditions to match threat to nation’s health of cancerA severe deficit has emerged in the funding of major health conditions such as cardiovascular disease and mental health, according to a new study calling for an urgent cash injection.While an estimated £29 per person is invested in cancer research each year, only half as much...
Government modelling expert Graham Medley says reopening schools is a priorityCoronavirus – latest updatesSee all our coronavirus coverageThe government may have to consider closing pubs in England to control the transmission of the coronavirus and to enable schools to reopen after the summer holidays, one of the government’s top scientific advisers has said.Prof Graham Medley, who chairs the...
For better protection, you may need to ... look a little weird and shield your peepersAt first, wearing a face mask felt a bit strange. Now, over five months into North America’s battle with Covid-19, I feel naked in public without one. Will goggles – previously the purview of steampunks and snowboarders – become the next article of protective equipment to go from weird to widespread?...
Your questions answered on what type of mask to wear to cut the risk of getting Covid-19Coronavirus – latest updatesSee all our coronavirus coverageYes. Different types of mask offer different levels of protection. Surgical grade N95 respirators offer the highest level of protection against Covid-19 infection, followed by surgical grade masks. However, these masks are costly, in limited supply,...
The first US astronauts to reach the International Space Station on an American spacecraft in nearly a decade might not come home this weekend as scheduled because of Hurricane Isaias, NASA said Friday.
Forecasters declared a hurricane warning for parts of the Florida coast Friday as Hurricane Isaias drenched the Bahamas on a track for the U.S. East Coast.

The Trump administration is moving to restrict what land and water areas can be declared as "habitat" for imperiled plants and animals—potentially excluding locations that species could use in the future as climate change upends ecosystems.
More durable prosthetics and medical devices for patients and stronger parts for airplanes and automobiles are just some of the products that could be created through a new 3-D printing technology invented by a UMass Lowell researcher.
Semiconductors are important materials in numerous functional applications such as digital and analog electronics, solar cells, LEDs, and lasers. Semiconducting alloys are particularly useful for these applications since their properties can be engineered by tuning the mixing ratio or the alloy ingredients. However, the synthesis of multicomponent semiconductor alloys has been a big challenge due...

An international group of scientists published a paper, Aug. 1, 2020, in a special edition of the journal Biological Conservation that lays out an ambitious global conservation plan for parasites. A separate paper also found that the responses of parasites to environmental change are likely to be complex, and that a changing world probably will see both outbreaks of some parasites and a total loss...

Ancient sediment found in a central Texas cave appears to solve the mystery of why the Earth cooled suddenly about 13,000 years ago.
The design of novel materials with superior characteristics by entropy stabilization is a very dynamic emerging research area in materials science. However, despite recent advances in entropy-stabilized metals and insulating ceramics targeted for structural applications, there is still a dearth of high-entropy semiconductors, which poses a major obstacle for the adoption of high-entropy materials...
