| If endangered primates disappear, so will their parasites. That's actually a problem Posted: 23 Sep 2021 04:11 PM PDT People are more aware of the plight of endangered gorillas than of gorillas' gut worms, and are understandably more enamored with mouse lemurs than their mites. Half of the world's roughly 500 primate species are at risk of extinction due to human activities such as hunting, trapping and deforestation. But the demise of the world's threatened primates could also trigger even more extinctions for the parasites that lurk within them, finds a new study. |
| Earliest evidence of human activity found in the Americas Posted: 23 Sep 2021 01:13 PM PDT Footprints at White Sands National Park in New Mexico confirm human presence over at least two millennia, with the oldest tracks dating back 23,000 years. |
| Vampire bats may coordinate with ‘friends’ over a bite to eat Posted: 23 Sep 2021 12:33 PM PDT Vampire bats that form bonds in captivity and continue those 'friendships' in the wild also hunt together, meeting up over a meal after independent departures from the roost, according to a new study. |
| Decoding birds’ brain signals into syllables of song Posted: 23 Sep 2021 12:33 PM PDT Researchers can predict what syllables a bird will sing -- and when it will sing them -- by reading electrical signals in its brain, reports a new study. The work is an early step toward building vocal prostheses for humans who have lost the ability to speak. |
| More support needed for pollination services in agriculture Posted: 23 Sep 2021 10:26 AM PDT The global decline of pollinators threatens the reproductive success of 90 per cent of all wild plants globally and the yield of 85 per cent of the world's most important crops. Pollinators -- mainly bees and other insects -- contribute to 35 per cent of the world's food production. The service provided by pollinators is particularly important for securing food produced by the more than two billion small farmers worldwide. An agroecologist points out that yields could be increased if pollinators were encouraged. |
| Carbon dioxide reactor makes 'Martian fuel' Posted: 23 Sep 2021 10:26 AM PDT Engineers are developing new ways to convert greenhouse gases to fuel to address climate change and get astronauts home from Mars. |
| An estrogen receptor that promotes cancer also causes drug resistance Posted: 23 Sep 2021 09:24 AM PDT Cancer cells proliferate despite a myriad of stresses -- from oxygen deprivation to chemotherapy -- that would kill any ordinary cell. Now, researchers have gained insight into how they may be doing this through the downstream activity of a powerful estrogen receptor. The discovery offers clues to overcoming resistance to therapies like tamoxifen that are used in many types of breast cancer. |
| Engineers introduce a new approach for recycling plastics Posted: 23 Sep 2021 09:24 AM PDT Engineers have come up with a revolutionary new method for tackling plastic pollution by harnessing the inner workings of proteins. The result? A whole new way of looking at plastic recycling. |
| New York waters may be an important, additional feeding area for large whales Posted: 23 Sep 2021 08:56 AM PDT A new study finds that that some large whale species (humpback, fin and minke whales) use the waters off New York and New Jersey as a supplemental feeding area feasting on two different types of prey species. |
| Intensified water cycle slows down global warming Posted: 23 Sep 2021 08:56 AM PDT A new study shows that the intensification of global hydrological cycle drives more ocean heat uptake into the deep ocean and moderates the pace of global warming. |
| Breast cancers: Ruptures in cell nuclei promotes tumor invasion Posted: 23 Sep 2021 08:56 AM PDT When cells multiply and migrate, they can be compressed and their nucleus may break open. This phenomenon causes DNA damage. Scientists have now shown that this facilitates the spread of cancer cells in breast tumors. |
| Ancient DNA analysis sheds light on dark event in medieval Spain Posted: 23 Sep 2021 08:56 AM PDT Researchers used ancient DNA analysis to identify a member of a population expelled from medieval Spain known as the 'Segorbe Giant'. The results have shed light on the brutal political decision that led to a dramatic change in population following the Christian reconquest of Spain. |
| Adjusting fatty acid intake may help with mood variability in bipolar disorders Posted: 23 Sep 2021 08:56 AM PDT Can specific dietary guidelines help people living with bipolar disorders better manage their health? Clinical trial results showed that a diet designed to alter levels of specific fatty acids consumed by participants may help patients have less variability in their mood. |
| A new method for removing lead from drinking water Posted: 23 Sep 2021 08:56 AM PDT Engineers designed a relatively low-cost, energy-efficient approach to treating water contaminated with heavy metals such as lead. |
| Researchers translate insect defense chemicals into eerie sounds Posted: 23 Sep 2021 08:56 AM PDT Sawfly larvae protect themselves by secreting cocktails of unpleasant, volatile chemicals intended to repel predators, particularly ants. Researchers can assess the effectiveness of these defenses by staging meetups, so-called bioassays, between prey and predator. But entomologist have taken a different approach, translating the secretions' chemical composition into sounds, and measuring how humans react. |
| Deadly virus’s pathway to infect cells identified Posted: 23 Sep 2021 08:56 AM PDT Researchers have discovered how Rift Valley fever virus enters cells, pointing the way to new therapies to treat deadly Rift Valley fever. |
| Posted: 23 Sep 2021 08:55 AM PDT Poxviruses have found a unique way of translating their genes into proteins in the infected organism. Scientists of the have been able to gain atomic-level insights into the functioning of the molecular machinery involved in the process. |
| New online tool to help residents reduce the impact of traffic-related air pollution Posted: 23 Sep 2021 07:21 AM PDT Researchers have released a new online tool to help schools, hospitals and residents understand and reduce the impact of traffic-related air pollution. |
| Non-native fish are main consumers of salmon in reservoirs Posted: 23 Sep 2021 07:20 AM PDT When warmwater fish species like bass, walleye and crappie that are not native to the Pacific Northwest, but prized by some anglers, overlap with baby spring chinook salmon in reservoirs in Oregon's Willamette River they consume more baby salmon than native fish per individual, new research found. |

| An 'evolutionary rescue route' towards coexistence of competitive plant species Posted: 21 Sep 2021 02:27 PM PDT In nature, plant species having the same pollinators experience 'reproductive interference' owing to competition, and their coexistence is thought to be possible only through resource partitioning. However, recent studies have suggested that coexistence can occur without resource partitioning if the species evolve to self-pollinate. Now, researchers from Japan provide credibility to this hypothesis with simulations, establishing a novel mechanism for the coexistence of competing flowering species. |
